-# Traces/metrics → OTLP HTTP collector (+ matching auth header)
+# Type: secret | Consumer: telemetry | Purpose: optional central monitoring.
+# Setting OTEL_EXPORTER_OTLP_ENDPOINT is the on/off switch for the whole telemetry path.
+# It turns on the API's own OpenTelemetry exporter (traces, metrics, logs with trace
+# context) AND auto-includes compose.telemetry.yml, which ships every other
+# container's stdout to the same collector.
+#
+# The endpoint and token come from the monitoring stack operator
+# (github.com/CMLPlatform/monitoring). One token, two consumers: compose folds it into
+# the SDK's header format for the API, and Alloy reads it directly.
+#
+# All three values must be set together (`just deploy-secrets-check` enforces it), and
+# the endpoint must be https:// — a plaintext endpoint would ship the token and every
+# container log in cleartext with no error anywhere.
+#
+# TELEMETRY_EDGE_KEY is a second, weaker credential: the Cloudflare WAF-skip rule for
+# otlp. matches it (infra/cloudflare-zone, TF_VAR_telemetry_edge_key must carry the
+# same value), so the bearer token itself never appears in a Cloudflare ruleset
+# expression. Rotate the key together with the zone rule; the token rotates with the
+# collector, independently.
+#
+# NOTE: both values reach the api and alloy containers as plain environment variables,
+# so anyone in this host's docker group can read them via `docker inspect`. That group
+# is already root-equivalent on the host; noted so it is a decision, not a surprise.
+#
+# PROJECT — the identity every signal is labelled with, and what the central stack's
+# ProjectTelemetrySilent rule keys on — is deliberately NOT here. It lives in

-Manifest ownership, env rules, and infra review guidelines live in the [engineering configuration docs](https://docs.cml-relab.org/architecture/engineering-config/).
+
+## Tooling and Configuration
+
+Use `.tool-versions` as the source of truth for local tool versions. Do not duplicate exact versions
+in docs unless a manifest or generated file requires it.
+
+Each configuration surface has one job:
+
+- root `justfile`: repo-wide orchestration and cross-project workflows
+- subrepo `justfile`: local commands for one project
+- `pyproject.toml`: Python dependencies and Python tool configuration
+- `pnpm-workspace.yaml`: JavaScript workspace membership, package-manager policy, and shared tooling
+  catalogs
+- `package.json`: JavaScript package dependencies and script wrappers
+- env files: runtime and build-time configuration only
+- GitHub workflow YAML: CI/CD wiring; move complex logic to versioned scripts
+- `.pre-commit-config.yaml`: repository policy hooks, run by [`prek`](https://github.com/j178/prek)
+  (a drop-in replacement for `pre-commit`). `just setup` installs the git hooks; `just pre-commit`
+  runs them all
+
+Keep new settings in the smallest surface that actually needs them. If a change adds or renames env
+vars, update the examples, validation rules, and affected docs in the same PR.
+
+## Quality Controls
+
+Run the relevant subrepo checks before opening a pull request:
+
+- backend: unit or integration tests, Ruff, and `ty`
+- app: Jest, TypeScript, and lint checks
+- www: Vitest, Astro checks, and Playwright where browser behavior changes
+- docs: formatting and build smoke check
+
+For cross-repo or policy changes, also run `just ci` from the root. GitHub Actions covers dependency
+review, container scanning, repository hygiene, and release artifact checks on every push.
+
+### Accessibility
+
+Accessibility is checked automatically. Every axe scan uses the same WCAG 2.0-2.2
+A/AA rule tags and strips animations for deterministic runs. `target-size` (2.5.8)
+is the only 2.2-only rule axe-core ships and it is enforced; 2.4.11 Focus Not
+Obscured and 2.4.13 Focus Appearance have no axe rule and are checked by hand.
+
+| Surface | Runtime axe scan                                                                                    | Static lint (every PR)                           |
+| ------- | --------------------------------------------------------------------------------------------------- | ------------------------------------------------ |
+| `www/`  | landing + privacy, contrast checked; ARIA landmark snapshots: `just www/test-e2e`                   | Biome `a11y`                                     |
+| `docs/` | homepage + getting-started `<main>`, contrast checked; snapshots: `just docs/test-e2e`              | Biome `a11y`                                     |
+| `app/`  | products list + detail on the Expo web build (`color-contrast` off): `just app/test-e2e-full-stack` | Biome `a11y` + `eslint-plugin-react-native-a11y` |
+
+The `www/` and `docs/` axe scans gate every PR that touches `www/`, `docs/`, or shared files. The
+`app/` scan needs the full Docker backend, so it runs post-merge or on demand; the per-PR net for
+the app is `eslint-plugin-react-native-a11y`, which validates RN accessibility props on each lint
+run. See [validate.yml](workflows/validate.yml).
+
+These are automated checks, so a passing run is a floor, not proof of WCAG
+conformance. The `app/` scan runs against the react-native-web build, so it does
+not exercise native VoiceOver/TalkBack. Two `app/` lint rules are deferred
+pending a labelling pass (`has-valid-accessibility-descriptors`,
+`has-valid-accessibility-ignores-invert-colors`, see `../app/eslint.config.mjs`).
+
+## Security
+
+For changes that touch authentication, authorization, uploads, device flows, admin APIs, secrets, or
+personal data, include security context in the pull request and update the relevant docs if behavior
+changes. See [SECURITY.md](SECURITY.md) for the reviewer checklist.
+

 ### Backend Test Architecture
 
-Keep the backend suite organized by execution cost first, then by feature:

-- `backend/tests/unit/`: pure unit tests only, with no database session, testcontainers startup, or real app lifespan
-- `backend/tests/integration/db/`: CRUD, ORM, and persistence behavior against the real schema
-- `backend/tests/integration/api/`: HTTP endpoint behavior against the ASGI app
-- `backend/tests/integration/flows/`: a small set of cross-boundary, multi-step scenarios

-
-### Database Migrations
-
-When changing schema:
-
-1. Create a migration.
-
-   ```bash
-   cd backend
-   just migrate-create "describe the change"
-   ```
-
-1. Review the generated file in `alembic/versions/`.
-
-1. Apply it.
-
-   ```bash
-   just migrate
-   ```
-
-For Docker-based runs, you can also use `just dev-migrate` from the repo root.
-
-### Email Templates
-
-MJML source templates live in `backend/app/templates/emails/src/`. Compiled HTML lives in `backend/app/templates/emails/build/`.
-
-Do not edit compiled output directly.
-
-To rebuild email templates:
-

+- For confirmed vulnerabilities, we will coordinate a fix and responsible disclosure timeline with
+  the reporter where practical.
 
 Please include enough detail for us to reproduce the problem. That saves time for everyone.
+
+## Security Baseline
+
+Relab uses [OWASP ASVS](https://github.com/OWASP/ASVS) as the application-security baseline and the
+[OWASP Secure Product Design](https://cheatsheetseries.owasp.org/cheatsheets/Secure_Product_Design_Cheat_Sheet.html)
+lens for product decisions. Keep controls simple, reviewable, and documented near the behavior they
+protect.
+
+For the deployed security posture, trust-boundary model, egress policy, browser runtime policy, and
+supply-chain artifact posture, see
+[Security and hardening](https://docs.cml-relab.org/operations/security/).
+
+Review security-sensitive changes against this baseline:
+
+- Context: self-hosted research and data-collection platform.
+- Components: backend, app, web, docs, PostgreSQL, Redis, storage, backups, OAuth, email, YouTube,
+  and RPi camera integrations.
+- Connections: clients and devices enter through the API; PostgreSQL and Redis stay on the internal
+  data network; external providers are explicit trust boundaries.
+- Code: authorization, validation, upload checks, browser security headers, and tests live close to
+  the behavior they protect.
+- Configuration: secrets, Compose policy, HTTPS, least-privilege database roles, and secure runtime
+  defaults are source-controlled where practical.
+
+Security-sensitive areas:
+
+- authentication and OAuth
+- public read APIs
+- authenticated mutation APIs — create endpoints accept an `Idempotency-Key` header and cache the
+  response in Redis for one hour.
+  - The cache entry is scoped by authenticated user id, endpoint (parent id included), and key, so
+    a cached response can never be replayed across accounts or targets.
+  - The entry also stores a hash of the request body: reusing a key with a different payload is
+    rejected with `422` instead of replaying the earlier record.
+  - If Redis is unreachable the request fails closed with `503` rather than risking a duplicate.
+- uploads and media — the `/uploads` mount serves stored bytes with a content-hashed,
+  immutable cache policy and `Cross-Origin-Resource-Policy: same-site`. That policy is
+  relaxed to `cross-origin` for `/uploads` alone in the `dev` and `testing` environments,
+  where the API and the frontends sit on different ports of `127.0.0.1` and Chromium blocks
+  the loads. The relaxation is derived from the environment, not configured, so staging and
+  production cannot opt into it.
+- admin APIs
+- RPi camera device APIs and WebSocket relay
+- backups, secrets, logs, and telemetry
+- release and security artifacts
+
+Valuable assets include accounts, profile/privacy settings, research records, uploaded media/files,
+OAuth and YouTube tokens, RPi camera credentials, refresh-token state, database dumps, backup
+material, and runtime secrets.
+
+Public read APIs are intentionally public: the product/component catalog and its research content
+are world-readable by design, since the platform exists to publish that data. `profile_visibility`
+hides owner identity attribution only — it is not a control over the underlying research content,
+and must never be treated as one.
+
+Account privileges are three independent things, and conflating any two of them is a privilege
+escalation:
+
+- `is_verified` gates whether an account may create records at all.
+- `is_superuser` grants the `/admin` routes. It does **not** imply trust with research data.
+- `role` (`contributor` by default, `lab`) is the contributor tier. It gates non-image
+  research-file upload and selects the upload quota tier. A superuser who is not `lab` is refused
+  a research-file upload exactly like any other contributor.
+
+Roles are assigned only by a superuser through `PUT /v1/admin/users/{user_id}/role`, which records
+an audit event. `role` is deliberately absent from `UserUpdate`: fastapi-users' safe update path
+strips a fixed set of privileged fields, so any new field on that schema would flow through
+self-service `PATCH /users/me` — keeping role off the schema makes that escalation unrepresentable
+rather than filtered. New and backfilled accounts start at `contributor`, so the tier fails closed.
+
+## Automated Checks
+
+Supply-chain and code-security checks:
+
+- Dependencies: GitHub Dependency Review / Dependency Graph and Renovate.
+- Runtime images: Trivy scans and SPDX JSON SBOM artifacts.
+- Infrastructure as code: Trivy misconfiguration scans for supported repo config files, OpenTofu
+  validates Cloudflare edge config, plus Relab Compose render and deploy secret path checks.
+- Source code: CodeQL.
+- Secrets: Gitleaks.
+- GitHub Actions workflows: actionlint and Zizmor.
+- Repository hygiene: OpenSSF Scorecard.
+
+Use `just security` for local maintainer diagnosis: it runs the dependency audits and the Gitleaks
+secret scan. Trivy, CodeQL, actionlint, Zizmor, and Scorecard run in CI.
+
+Release SBOM assets are attested as files and uploaded with GitHub releases.
+
+## Maintainer Review
+
+Automated checks do not replace reviewer judgment. For changes that touch authentication,
+authorization, uploads/media, RPi camera or device flows, admin APIs, deployment, secrets,
+dependencies, or personal data, confirm:
+
+- authorization is enforced server-side, not only hidden in a client — hiding an upload affordance
+  from a client that lacks the role is a UX choice, never the control
+- input is validated at API, upload, form, and device boundaries
+- browser-rendered values stay on framework escaping paths; raw HTML sinks and dynamic URLs are
+  isolated, validated, and tested
+- logs do not include tokens, passwords, private URLs, OAuth material, or other sensitive values
+- secure defaults fail closed in production and staging
+- auth, permission, upload, and device-flow behavior has focused test coverage
+
+Filtering a route out of a public OpenAPI schema hides it from the docs, not from attackers.
+Authorization must be enforced in backend dependencies and services regardless of which schemas list
+the route.

+# Product
+
+What Relab is, who it serves, and which facts about it are settled. This covers the product as a
+whole; `app/`, `www/`, and `docs/` are surfaces of it. Per-surface strategy lives in the surface
+briefs.
+
+## Purpose
+
+Relab is a data collection and viewing platform for a PhD at Leiden University (CML), built around
+the circular economy and the 9R strategies. Users document a physical product, break it into
+components, and tag those components with materials and circularity observations. The output is a
+structured, citable research dataset about how real products are built and how recoverable their
+materials are.
+
+Success has an order, and it is load-bearing:
+
+1. PhD evidence and credibility. The platform must stand up as defensible research infrastructure.
+1. Outside contribution and a published dataset. Both are real goals. Neither outranks credibility
+   when they conflict.
+
+Proof beats conversion. A surface that recruits contributors at the cost of looking like serious
+research infrastructure has made the wrong trade. Capture accuracy also outranks capture speed.
+
+Non-goals, from `docs/.../project/use-cases.md`: not a PLM system, not mass-scale crowdsourcing,
+not an automated computer-vision pipeline, not an elastic cloud platform.
+
+## Platform
+
+Web ships. `build` is `expo export -p web`, E2E runs Playwright against that export, and the
+deployed surface is `app.cml-relab.org` behind Caddy.
+
+Native iOS and Android are configured in `app/app.json` but this repo's tooling does not build or
+release them. Native remains a live target, so design nothing that could not be carried to a phone
+build.
+
+## Users
+
+The audience is staged, in build order:
+
+1. CML lab researchers and students. Now, primary. Internal, authenticated, trained.
+1. External contributors. Near term. Public profiles at `/users/[username]`, a
+   `profile_visibility` preference, and email-verification gating already anticipate them.
+1. Repair-café visitors. Medium term. Untrained, one-off, on-site.
+1. General citizen scientists. Long term.
+
+Levels 3 and 4 are a trajectory, not a current requirement. They are recorded because they change
+what "good" means for onboarding, empty states, terminology, and error recovery. A trained lab user
+tolerates schema vocabulary that a repair-café walk-in will not.
+
+Access rules:
+
+- Signed-out visitors can browse. `/` redirects to `/products` and the list renders anonymously.
+- Verification gates creation. Unverified accounts see "Verify your email to start creating".
+- A username is required to own records.
+- `isSuperuser` grants the backend's `/admin` routes and nothing in the app. The app displays it as
+  a badge and is not planned to become an admin surface.
+
+Accounts carry a `role` of `contributor` (default) or `lab`, alongside the three booleans. `lab`
+grants non-image research-file upload and the larger upload quota. Only a superuser assigns a role,
+through `PUT /v1/admin/users/{user_id}/role`; `role` is absent from the self-service update schema.
+Existing accounts were backfilled to `contributor`, so lab members are promoted by hand after
+deploy. The enum stops at two values on purpose: a "viewer" is an unverified account and an "admin"
+is a superuser, so more rungs would give each of those two sources of truth.
+
+## Positioning
+
+Site line: "Relab | Product data and disassembly records for the circular economy."
+
+The mechanism a neighbouring product could not truthfully copy: teardown records captured by people
+with the product physically disassembled in front of them. Recursive product → component hierarchy
+of unbounded depth, photographic evidence at every node, and per-node circularity observations.
+Field-captured primary data, not scraped specifications or inferred bills of materials.
+
+Relab works downstream, at the point of failure, with the people who already open products. That
+vantage captures as-failed composition, wear, and recoverability that as-designed producer
+specifications never record.
+
+The sharpest comparison: repair groups have logged more than 400,000 records under the Open Repair
+Data Standard, but those are event-level, with no component hierarchies, no masses, no geometry.
+Relab's contribution is exactly that missing depth.
+
+**Careful with the 9R framing.** The 9R strategies motivate the project and supply its wordmark.
+They are not applied per record. The platform does not tag a record with an R-strategy and does not
+recommend one. Do not write copy implying records are classified, scored, or captured against the
+9R ladder.
+
+## Operating context
+
+**The bench.** A person with a product taken apart in front of them, hands occupied, camera in use,
+working through a hierarchy one node at a time. Capture is interleaved with disassembly, not done
+afterward from notes.
+
+**Capture-first creation.** `/products/new` opens straight into a capture screen, POSTs, then
+`replace`s to the record in edit mode. It uses `replace` so a back gesture cannot re-submit the
+form. `components/new` repeats this one level down. Nesting is uncapped; breadcrumbs truncate at 12
+ancestors.
+
+**Raspberry Pi camera rig.** An optional paired capture device, enabled per user via the
+`rpi_camera_enabled` preference. Pairing uses a 6-character code plus a camera name. Pi captures can
+return `queued`, meaning the frame is on the device but not yet uploaded. A YouTube live-streaming
+flow sits on the same device.
+
+**Connectivity is not assumed.** Save mutations pause offline and fire on reconnect. The UI shows
+"Queued — sends when online".
+
+**Screen sizes.** Phone layout is the base. Web adapts at `md` (768) and `lg` (1024); at `lg` a
+persistent `TopNav` replaces the stack header. `useBreakpoint()` is web-only, so native always reads
+as phone.
+
+## Constraints that shape design
+
+**Data model.** One entity with `role: 'product' | 'component'` and a parent link. Physical
+properties are weight, width, height, depth, with `undefined` as the deliberate "unset" sentinel.
+Circularity properties are exactly three free-text notes: Recyclability, Disassemblability,
+Remanufacturability.
+
+**Uncertainty is data, not failure.** "Likely polypropylene, unconfirmed" is a good observation, and
+contributors are told to leave a field empty rather than pick the closest wrong match. So an empty
+or unconfirmed field must never render as an error, a warning, a red state, or a completeness
+penalty. A record shown as a progress bar toward 100% would reward false precision and damage the
+dataset.
+
+**Two hardware tiers, and the low one is legitimate.** A phone or tablet plus a scale and a ruler is
+enough to contribute usefully. The Pi rig only pays off for repeatable imagery across many products.
+No surface may present it as a prerequisite.
+
+**Uploads.** Images only in-app: jpeg, png, webp, gif, bmp, 10 MB hard cap each. The backend rejects
+an upload unless extension, declared MIME type, and sniffed content agree. Uploads are sequential by
+design. Quotas are tiered by role (contributor 1,000 files / 1 GB; lab 20,000 files / 20 GB) and
+`/users/me` reports limits and usage. There is no per-product limit.
+
+**Idempotency.** Creates carry an `Idempotency-Key` minted once per draft, so a retry, a rehydrated
+draft, or a second Save press cannot double-create.
+
+**CPV taxonomy.** Product and component types come from the EU procurement taxonomy, shipped as a
+~2 MB bundled `cpv.json` loaded once per session.
+
+**Auth.** Password plus exactly two OAuth providers (Google, GitHub). MFA is TOTP with single-use
+recovery codes. OAuth-only accounts have no usable password, which changes whether unlinking a
+social login requires one.
+
+Runtime hardening lives in `app/Caddyfile`; the security baseline lives in
+[.github/SECURITY.md](.github/SECURITY.md).
+
+## Deliberately absent
+
+Recorded so nobody assumes them into existence:
+
+- **Video is URL-only.** `Product.videos` holds links. Self-hosted video is deferred, roughly a year
+  out. Do not design upload affordances for it.
+- **Non-image file upload is lab-only**, in a "Research files" block in the Media section, edit mode
+  only, base product only. No general-purpose upload affordance exists outside it.
+- **Offline queueing is web-only in practice.** `onlineManager` has no native connectivity listener
+  yet, so a native build never pauses. Tracked as a TODO in `app/src/app/_layout.tsx`.
+- **No localization.** All copy is hardcoded English. This becomes a real barrier at the repair-café
+  stage and is currently unplanned.
+- **Three documented design goals are not shipped:** the value-return-to-contributors loop, taxonomy
+  interoperability, and per-record 9R classification. Copy implying any of them is live is a factual
+  error.
+- **No published dataset release, no screenshots, no app store listing, no testimonials, benchmarks,
+  pricing, or adoption figures.** A first dataset release and the first screenshots are expected
+  soon; write about them in the present tense only once they land.
+
+**Three numbers that look alike and are not.** The pilot study produced 1,331 component records and
+3,610 images from 78 products (`docs/src/content/docs/project/index.md`); those are historical, not
+the live dataset. `www/src/lib/landing.ts` fetches live totals from `backend/app/api/stats` at build
+time; those are current. `www/src/components/BrandHero.test.ts` pins a fallback fixture whose 3610
+collides with the pilot image count by coincidence. Never conflate them.
+
+## Brand commitments
+
+- **The name is "Relab" in all text:** copy, titles, alt text, aria-labels, metadata. "R9lab" is a
+  visual wordmark device that lives only in logo artwork. Never as text, never "R-nine-lab".
+- **Never write "Reverse Engineering Lab".** This is an IP-law concern, not a style preference.
+- **The name, logo, and wordmark carry no licence.** Nominative use needs no permission.
+- **Direction: "Cyanotype & Manila — the colour of engineering documentation."** "Verdigris &
+  Copper" is the documented fallback, still pending supervisor review.
+- **The accent is data, not decoration.** Manila labels facts: R-numbers, record IDs, status pills.
+  It never fills a button and never drives a hover or pressed state. Primary blue carries all
+  interaction. This is the rule most likely to be violated by visual enthusiasm, and the one that
+  keeps the interface reading as engineering documentation.
+- **Palette is machine-enforced.** `assets/brand.css` and `assets/palette.json` are the sources;
+  `app/src/theme/__tests__/palette-sync.test.ts` fails if they drift.
+- **Type: IBM Plex superfamily** on web and docs. The Expo app stays on platform system fonts for
+  native feel and Dynamic Type, capped at 2×. It adopts the scale and palette, not the typeface.
+- **Form language "Flat & Sharp":** radius 6/8/12/9999, inline surfaces flat with a 1px hairline,
+  one `shadow-overlay` tier for things that genuinely float.
+- **Icons: `lucide-react-native` at 16/20/24.** Brand marks are vendored Simple Icons SVGs rendered
+  with `currentColor`, never recoloured to their own palette.
+- **Voice:** circularity framing, lab vernacular (products, components, materials, samples).
+
+## Principles
+
+1. **The bench beats the desk.** Any step, confirmation, or mode switch between observing and
+   recording costs real data.
+1. **The dataset is the deliverable.** Accuracy outranks speed and delight. Idempotent creates,
+   offline queueing, and unset sentinels all exist because a lost or duplicated observation is worse
+   than a slow one.
+1. **Nothing is gated that does not need to be.** Each existing gate earns its place. No new one
+   should appear without the same justification.
+1. **Vocabulary is a staged liability.** Prefer terminology that survives the audience expansion
+   over terminology that mirrors the schema.
+
+## Accessibility
+
+**Target: WCAG 2.2 AA** across www, docs, and app. Chosen over 2.1 AA because Leiden University
+public surfaces fall under the EU Web Accessibility Directive via EN 301 549.
+
+All three surfaces tag `wcag2a`/`wcag2aa`/`wcag21a`/`wcag21aa`/`wcag22a`/`wcag22aa`; www and docs
+fail on any violation, the app filters to `serious` and `critical` (RN-Web emits minor/moderate
+noise it cannot fix). axe-core 4.12 ships exactly one 2.2-only rule, `target-size` (2.5.8), and it
+is now enforced — it passes on www, docs, and the app's products and detail screens, backing up
+`MIN_TAP_TARGET = 44`.
+
+A named gap remains, narrower than before: **2.4.11 Focus Not Obscured** (sticky headers, the docs
+sidebar) and **2.4.13 Focus Appearance** (pairs with `--color-ring` on www) have no axe rule at all
+and are verified by hand.
+
+Enforced today:
+
+- axe in Playwright against the web build, gating on `serious` and `critical`. `color-contrast` is
+  disabled there because RN-Web emits noise the app cannot fix; contrast is verified instead in
+  `semantic-contrast.test.ts` and `palette-sync.test.ts` against the committed palette.
+- `MIN_TAP_TARGET = 44`, with icon-only controls keeping a ≥44px hit area.
+- `eslint-plugin-react-native-a11y` blocks: `lint:react` must pass with zero warnings.
+- `prefers-reduced-motion` via `ReduceMotion.System` on Reanimated transitions.
+- Screen-reader parity handled explicitly: `accessibilityLiveRegion` is Android-only and `aria-live`
+  is web-only, so iOS gets an `AccessibilityInfo.announceForAccessibility` call.
+
+No manual keyboard or assistive-technology pass has been run on any surface. Automated coverage is a
+floor.
+
+The public statement lives at `www/src/pages/accessibility.astro` (copy in
+`src/copy/accessibility-content.ts`), linked from the site footer. It claims partial conformance and
+names what is untested, which is the honest shape and the one the Web Accessibility Directive asks
+for.
+
+That page is the user-facing half only. The compliant artifact under the Dutch implementation
+(Tijdelijk besluit digitale toegankelijkheid overheid) is a register entry per domain, filed through
+the invulassistent at toegankelijkheidsverklaring.nl and signed by someone who can bind the
+university. **Open, and not the maintainer's alone to close:** ask Leiden's accessibility
+coordinator whether `cml-relab.org`, `app.cml-relab.org`, and `docs.cml-relab.org` are covered by an
+existing entry or need their own. A second statement that contradicts the university's is worse than
+none, so the page deliberately omits a feedback response window and an escalation body until that
+answer lands. The decree's own baseline is WCAG 2.1 AA, so the 2.2 target clears it with room.

+The RPi camera plugin's schema (`openapi.rpi-cam.json`) is published here for reference but is

+alike.
+
+Two limits that no licence changes. Personal data is governed by the GDPR regardless of the licence,
+so it is the sanitisation applied when building a release — not CC BY — that makes publication
+lawful. And CC BY grants no trademark rights: teardown photographs necessarily show brand marks and
+model numbers, which the licence covers as images without licensing the marks themselves.

+# Design System: Relab App
+
+## Overview
+
+**Creative North Star: "Cyanotype & Manila — the colour of engineering documentation"**
+
+*Mirrors assets/DESIGN.md:8 — change it there first.*
+
+The app is a field instrument, not a showcase. Its user is at a bench with a product in pieces,
+hands occupied, working down a hierarchy one node at a time. Everything here follows from that:
+the interface is a surface you write **on**, not one you look **at**. Prussian blue carries every
+action; manila marks the data. Surfaces are flat, edges are sharp, and nothing floats unless it
+genuinely floats above something else.
+
+Component character is **precise and unfussy** — controls behave like well-made lab instruments:
+exact, quiet, no ornament, no theatre. A control's job is to be unambiguous at a glance and
+forgiving under a thumb, not to reward attention. Where a decision is between expressive and
+legible, legible wins; the record outlives the session.
+
+This app diverges from its sibling web surfaces in two ways, each stated as a rule below: it
+stays on **platform system fonts** rather than IBM Plex, and it keeps the **eyebrow** type
+variant that www and docs do not use. Both are deliberate.
+
+**Key Characteristics:**
+
+- Flat base, exactly one floating tier — no ambient shadow anywhere else.
+- Blue is interaction, manila is data. The two never trade jobs.
+- 44px touch floor, monospace with tabular figures for every measurement.
+- Dark mode is parity, not an afterthought — every token is a scheme-aware pair.
+- Motion is functional and always honours `prefers-reduced-motion`.
+
+### Why brand rules are restated here rather than referenced
+
+`assets/DESIGN.md` is the estate-wide brand source, and this file is the app's. Someone building
+a screen reads this one. A rule that lives here only as a cross-reference to another document is
+a rule they will not read, and every rule below has been broken at least once in this codebase by
+someone who did not know it existed.
+
+So the five load-bearing brand rules are restated here **in full**. Each carries a
+`Mirrors assets/DESIGN.md:NN` marker, so one search over the repository lists every copy of every
+mirrored rule and the line it came from — a copy that names its source is a cache, a copy that
+does not is a fork.
+
+The duplication is deliberate. Change a mirrored rule in `assets/DESIGN.md` first, then update
+its copies. Do not consolidate them back into references.
+
+## Colors
+
+A cyanotype palette: a deep Prussian blue against near-white paper, with a single earthy manila
+accent reserved for data. Both schemes are generated from `assets/palette.json` into
+`src/theme/palette.generated.ts` and verified by `src/theme/__tests__/palette-sync.test.ts` —
+do not hand-edit either.
+
+### Primary
+
+- **Prussian Blue** (`#1F4C96` light / `#8FB8FF` dark): Every interactive element. Buttons,
+  links, focus rings, active navigation, selected state. If a thing responds to touch, it is
+  blue.
+
+### Secondary
+
+- **Slate** (`#565E71` / `#BEC6DC`): Supporting chrome and secondary labels where full
+  foreground weight would over-emphasise.
+
+### Tertiary
+
+- **Manila** (`#8F6212` / `#E3B95C`): Data labels only — R-numbers, record IDs, live and status
+  pills, strategy tags. Never an interaction colour.
+
+### Neutral
+
+- **Paper** (`#FAFBFE` / `#11141D`): Page background.
+- **Ink** (`#16202E` / `#E2E6EE`): Primary text.
+- **Card** (`#F0F3FA` / `#1A2030`): Cards, panels, list rows. Reached in code as `bg-card`.
+- **Muted Ink** (`#44474F` / `#C4C6D0`): Secondary text; meets 4.5:1 on paper in both schemes.
+- **Hairline** (`#C4C6D0` / `#44474F`): The canonical border. Dividers, card edges, input
+  strokes.
+
+### Status
+
+Scheme-aware pairs in `src/theme/tokens.ts`: success `#2E7D32`/`#7BC67E`, warning
+`#A05A00`/`#FFB74D`, danger = destructive, info `#1565C0`/`#90CAF9`, offline `#5A6675`/`#9E9E9E`,
+live = manila.
+
+### Named Rules
+
+**The Data-Label Rule.** The manila accent is a **data-label colour** — R-numbers, record IDs,
+small data labels, live/status pills, strategy tags. **Accent is for small text, never for
+mass.** It never fills a button, never drives a hover or pressed state, and never paints bars,
+big figures, or large areas. Interaction is always primary blue. *Mirrors
+assets/DESIGN.md:173-190 — change it there first.*
+
+**The One Tint Rule.** `tokens.surface.accent` — primary at 12% — is the single canonical
+selected/tinted fill: chips, history rows, toggles, active nav. The Tailwind spelling is
+`bg-primary/12`. There is exactly one tint value; `bg-primary/10` is not a second opinion, it is
+a bug.
+
+**The Primary-Strong Rule.** Pressed and hover states on filled controls use the real
+`primary-strong` shade — `#143567` light / `#BAD3FF` dark — not alpha on the primary. In Tailwind
+that is `active:bg-primary-strong` / `hover:bg-primary-strong`.
+
+`assets/brand.css` and `assets/palette.json` are separate vocabularies — web-brand and
+shadcn-shaped — reconciled by the `BRAND_PARITY` table in `scripts/sync_brand_assets.py`.
+`primaryStrong` is in both, so `just assets-check` fails if the app and web values drift.
+
+Note the dark-scheme direction: `primary-strong` is *lighter* than `primary` in dark mode
+(#BAD3FF over #8FB8FF). Pressed means more energy, not more ink.
+
+## Typography
+
+**Display / UI Font:** platform system font (San Francisco on iOS, Roboto on Android, system UI
+stack on web)
+**Data / Label Font:** platform monospace (Menlo on iOS, `monospace` elsewhere), with
+`font-variant: tabular-nums`
+
+**Character:** Neutral and native. The app borrows the *scale and palette* of the brand's IBM
+Plex system without shipping the typeface — measurements line up in monospace, everything else
+gets out of the way.
+
+### Hierarchy
+
+- **Display** (38/44): The one big number or name on a screen. Profile hero, account identity.
+- **Title** (24/30): Screen and section titles.
+- **Heading** (19/24): Subsection headers, card titles.
+- **Body** (16/26): Prose, descriptions, form values. Selectable by default.
+- **Label** (13/18, +1.3 tracking): Field labels and dense chrome.
+- **Caption** (13/18): Helper text, timestamps, secondary annotations.
+- **Data** (14/20, monospace, tabular figures): Every measurement, ID, count, and code. If it is
+  a number the user might compare to another number, it is `data`.
+- **Eyebrow** (13/18, +1.3 tracking, uppercase, muted ink): Labels a **value inside a compact
+  tag**.
+
+### Named Rules
+
+**The System-Font Rule.** The app **intentionally stays on platform system fonts** — native
+feel, Dynamic Type support, zero load cost. It adopts the brand's scale and palette, not its
+typeface. www and docs use IBM Plex; this divergence is deliberate and must not be "unified".
+*Mirrors assets/DESIGN.md:33-35 — change it there first.*
+
+Dynamic Type is capped at 2x, and the cap belongs on **every** text primitive, not just
+`AppText`: `ui/text` renders every button label plus HeroStats, ComponentRow, GoLiveDialog and
+ProductDelete, so a cap that misses it is not app-wide. Both apply it by default.
+
+**The Eyebrow-Is-A-Datum Rule.** `eyebrow` labels a **value inside a compact tag**. It is not a
+decorative kicker above a heading — a heading under an eyebrow makes the eyebrow chrome, which
+is why www and docs carry none at all. This is the Data-Label Rule wearing different clothes:
+an eyebrow names a datum, exactly as manila colours one. *Mirrors assets/DESIGN.md:175-179 —
+change it there first.*
+
+**The Ramp Rule.** Every text size comes from the eight variants above. An inline `fontSize:`
+is a defect unless it carries a comment naming the reason no ramp step fits.
+
+## Layout
+
+`PageContainer` is the scaffold: a max-width column with gutters that widen at `md` (768) and
+`lg` (1024), plus `fullBleed` and `phoneFullBleed` escape hatches for galleries and hero media.
+
+Breakpoints are **web-only by design** — `useBreakpoint()` hard-gates `isMd`/`isLg` on
+`Platform.OS === 'web'`, so a native tablet deliberately reads as phone-tier. The adaptation axis
+is viewport width on web, never operating system.
+
+The chrome swap at `lg` is the one structural change: the persistent `TopNav` app bar appears
+and the stack header hides, never both. Below `lg`, stack headers plus the bottom tab bar.
+Detail screens follow the same line — a horizontal chip row on phone, a 200px outline column at
+`lg` — rendering the *same* nav item component in both, so only the container changes.
+
+Spacing rhythm is 4/8/16 with an 8px minimum gap.
+
+## Elevation & Depth
+
+**Flat base, one floating tier.** Inline surfaces — cards, rows, inputs, chips — are flat: a 1px
+hairline border plus a `card` fill, **no shadow**. Depth comes from the hairline and the fill
+step, not from light. Shadow is reserved for surfaces that genuinely float above the page.
+
+### Shadow Vocabulary
+
+- **`shadow-overlay`** (light `0 8px 24px rgba(20,40,80,.16)`, dark `0 8px 24px rgba(0,0,0,.55)`):
+  Menus, dialogs, bottom sheets, the FAB, toasts. This is the only shadow in the system.
+
+`src/theme/tokens.ts` reads this from `designTokens.rn.shadowOverlay[scheme]`. React Native
+cannot consume the CSS string the generator emits for web, so the generator emits an RN-shaped
+variant alongside it and the app consumes that — never re-declare the values here. The Android
+`elevation` is a scheme pair (8 light / 12 dark): a dark ground needs more lift than a light one
+for the same perceived depth, matching the shadow-opacity split.
+
+### Named Rules
+
+**The Inverse-Pair Rule.** `inverseSurface` may only ever carry `inverseOnSurface` (primary
+text) and `tokens.text.inverseMuted` (secondary). Both inks assume an inverted backdrop, so
+pairing either with a same-polarity surface inverts the contrast and the text disappears — the
+failure is total, not marginal, and it is invisible to a reader of the source because each token
+name looks reasonable on its own.
+
+The rule is enforced by construction: take the ground and both inks together from
+`useInverseSurface()` (`src/theme/inverseSurface.ts`) rather than reading the tokens separately.
+Tooltips, toasts and the live-stream banner all use it. Measured on the current palette, the pair
+gives 10.5:1 dark / 11.8:1 light for primary ink and 5.4:1 / 5.8:1 for muted.
+
+**The One Tier Rule.** There is exactly one shadow. Inline surfaces get a hairline and no
+shadow; floating surfaces get `shadow-overlay`. A second elevation tier, a coloured glow, or a
+shadow stacked on an already-floating element is a defect, not an emphasis technique. *Mirrors
+assets/DESIGN.md:121-129 — change it there first.*
+
+## Shapes
+
+Flat and sharp — the geometry of an engineering document, deliberately replacing the MD3/Paper
+era of pill buttons, ambient shadows, and oversized radii the app was born in.
+
+| Token            | Value  | Use                                        |
+| ---------------- | ------ | ------------------------------------------ |
+| `radius.control` | 6px    | Buttons, inputs, chips, segmented controls |
+| `radius.card`    | 8px    | Cards, panels, list rows                   |
+| `radius.overlay` | 12px   | Dialogs, bottom sheets, menus, FAB         |
+| `radius.full`    | 9999px | Avatars and **true pills only**            |
+
+All four map through `src/constants.ts:41`. Use the token, never a literal.
+
+### Named Rules
+
+**The True-Pill Rule.** `radius.full` is for avatars and genuine pills only. A square icon
+button is not a pill — a 44×44 control with `rounded-full` is a circle pretending to be one, and
+it breaks the sharp geometry everything else maintains. *Mirrors assets/DESIGN.md:113-116 —
+change it there first.*
+
+## Components
+
+### Buttons
+
+- **Shape:** Gently squared (6px, `radius.control`), 44px minimum height.
+- **Primary:** Solid Prussian blue, white text. Pressed: `active:bg-primary/90`.
+- **Outline / Ghost / Tonal:** Blue ink, transparent or 12% tinted fill, hairline border on
+  outline.
+- **Destructive:** Solid `#BA1A1A`, white text. Never the keyboard default in a dialog.
+- **Loading:** Inline spinner tinted to the variant's foreground; the label stays.
+
+### Chips
+
+- **Style:** Two segments — a title segment in blue on `card`, and a value segment on solid
+  primary with white ink. 6px radius, 44px minimum height.
+- **Error:** Danger-tinted fill **plus** a border **plus** an alert icon **plus** ", required"
+  composed into the accessible name. Never colour alone.
+
+### Cards / Containers
+
+- **Corner:** 8px (`radius.card`).
+- **Background:** `card`. **Border:** 1px hairline. **Shadow:** none, ever.
+
+### Inputs / Fields
+
+- **Style:** Borderless by default on a `card` fill; bordered variant available. 6px radius,
+  44px minimum height.
+- **Error:** Message rendered by `FormField` with a `nativeID` linked via
+  `accessibilityLabelledBy`, so the error is programmatically associated, not merely adjacent.
+
+### Navigation
+
+- **Below `lg`:** stack header plus custom bottom tab bar.
+- **At `lg` (web):** persistent `TopNav`, stack header hidden.
+- **Items:** `min-h-11`, active `bg-primary/12` with blue ink, inactive at 70% opacity, web
+  `focus-visible:ring-2`.
+
+### Focus indicators
+
+Every interactive control takes `WEB_FOCUS_RING` from `src/constants.ts`:
+`focus-visible:outline-2 focus-visible:outline-solid focus-visible:outline-offset-2 focus-visible:outline-ring` — a 2px Prussian-blue outline, 2px clear of the control.
+
+### Named Rules
+
+**The Painted-Focus Rule.** A focus indicator is only real if it *paints*, and in this codebase
+a plausible-looking one may not. Every control here also carries a base-layer reset —
+`shadow-none` for the flat form language, `outline-none` for the resting state — and those resets
+silently disarm the usual mechanisms: a Tailwind ring compiles to a box-shadow layer that
+`shadow-none` flattens, and `outline-2` compiles to `outline-style: var(--tw-outline-style)`,
+which `outline-none` sets to `none` unconditionally. In both cases the width and colour compute
+correctly and nothing appears.
+
+So the indicator is an explicit `outline` with an explicit `outline-solid`, and: **never assert a
+focus indicator by its utility class.** Assert the computed result — `outlineStyle !== 'none'`
+while `:focus-visible` matches. `app/e2e/accessibility.spec.ts` does this; keep it. Never add a
+focus style to a control without measuring it in a browser.
+
+### Status Pill
+
+24px tall, `radius.control`, `label` type. Solid or soft variant. The **live** pill is the one
+sanctioned manila fill in the entire app — and it is a small pill, which is the entire
+justification.
+
+### Signature: the Spec Row
+
+Monospace value, manila eyebrow label, hairline separator. This is the app's most characteristic
+pattern and where the whole system is legible at once: data in mono, its label in manila, and
+nothing else competing.
+
+## Do's and Don'ts
+
+### Do:
+
+- **Do** use `tokens.surface.accent` (or `bg-primary/12`) for every selected or tinted fill.
+- **Do** use the `data` variant for every measurement, ID, count, and code — tabular figures
+  make columns of numbers comparable.
+- **Do** pair every colour-carried meaning with a second signal: an icon, a border, or text.
+- **Do** apply `MIN_TAP_TARGET` (44) to every interactive control, including icon-only ones.
+- **Do** pass `ReduceMotion.System` on every Reanimated animation. Currently 19 of 19 sites do;
+  keep it perfect.
+- **Do** keep entrance motion in the 150–300ms band, with exits deliberately shorter.
+- **Do** comment any deliberate departure from a token, naming what it departs from.
+
+### Don't:
+
+- **Don't** paint manila on anything large — no bars, no big figures, no glows, no banners. It
+  labels data; it does not decorate.
+- **Don't** use manila or any accent for hover, pressed, focus, or selection. Interaction is
+  blue.
+- **Don't** add a second shadow tier, a coloured glow, or a shadow on an inline surface.
+- **Don't** use `rounded-full` on anything that isn't an avatar or a true pill.
+- **Don't** introduce an inline `fontSize:` without a comment explaining why no ramp step fits.
+- **Don't** use MD3 `*Container` roles (`errorContainer`, `primaryContainer`, …) or the tonal
+  `elevation.level*` surfaces. They are Paper-era residue; the flat/sharp system replaces them.
+- **Don't** pair `inverseOnSurface` or `inverseMuted` with anything except `inverseSurface` —
+  take all three from `useInverseSurface()`. A same-polarity ground makes the text vanish.
+- **Don't** render an empty or unconfirmed field as an error, a warning, a red state, or a
+  completeness penalty. Uncertainty is first-class research data — "likely polypropylene,
+  unconfirmed" is a good observation. **Never add a completeness meter or a progress-to-100%
+  bar**: it would reward false precision and damage the dataset.
+- **Don't** reintroduce react-native-paper, or add a new icon family alongside
+  `lucide-react-native`.

+# Relab App
+
+The `app` subrepo contains the Expo / React Native app used for authenticated data collection.
+
+## Quick Start
+
+```bash
+just install
+just dev
+```
+
+The Expo dev server runs on <http://127.0.0.1:8011>.
+
+You will usually want the backend running as well. If the API is not on localhost, set
+`EXPO_PUBLIC_API_URL` in `.env.local`.
+
+Docker development ports are localhost-only. If you want to open the Expo app from another phone,
+tablet, or computer on your LAN, run the Expo server directly from this subrepo with `just dev`
+instead of using the Docker app service.
+
+## Stack
+
+- **Runtime:** Expo SDK 57, React 19, React Native 0.86, React Native Web.
+- **Routing:** [Expo Router](https://docs.expo.dev/router/introduction/) (file-based, typed routes).
+- **Data fetching:** [TanStack Query](https://tanstack.com/query) against a
+  FastAPI backend. Types are generated from the backend's OpenAPI schema.
+- **Client state:** React context + feature-local hooks/reducers.
+- **Forms:** React Hook Form + Zod resolvers.
+- **UI kit:** Uniwind (Tailwind v4 for React Native) + vendored react-native-reusables
+  primitives in src/components/base/.
+  Theme (colors, type scale, semantic tokens) is delivered via `AppThemeProvider`/`useAppTheme()`
+  (src/theme/); react-native-paper is not used — do not reintroduce it.
+- **Compiler:** React Compiler enabled via `babel-plugin-react-compiler`.

+```
+
+`base/` components are generic primitives (incl. vendored react-native-reusables
+under `base/ui/`); other component folders are domain-scoped. Feature logic
+lives in `src/features/`. Keep imports flowing inward (features may use `base`,
+not the reverse).
+
+Where two features share cache state, the contract gets its own neutral module
+rather than a mutual import: `features/product-entity/` holds the single-product
+query options and invalidation that `features/cameras` writes and
+`features/products` reads, so the products→cameras dependency stays one-way.
+
+`base/` holds two kinds of component. Most are generic primitives. A few are app
+chrome — `TopNav`, `HeaderRightPill`, `StaticBackground` — which read app
+context (auth session, theme mode) and are not reusable outside this app. They
+live in `base/` because `_layout.tsx` composes them into the shell; the rule
+they still keep is the import direction: chrome renders what it's given (e.g.
+`useVisibleDestinations()` from `src/navigation/`) rather than importing from
+`src/features/`.
+
+`src/components/base/ui/` is vendored react-native-reusables output — regenerate via the RNR CLI
+rather than hand-refactoring.
+
+Adoption of that kit is deliberately partial. Call sites use a vendored primitive directly when its
+look and behavior are what they want (`ui/input` in Searchbar and capture, `ui/badge` for read-only
+tags, `ui/button`, `ui/text`). The hand-rolled `base/` components that look like counterparts —
+`TextInput`, `InfoTooltip`, `Chip`, `AppDialog`, `Menu` — each carry behavior the primitive does
+not (theme-driven error states, auto-dismiss and a mobile-web modal fallback, pressable two-segment
+pills, RN-core Modal focus traps and anchor measuring). Each was assessed in August 2026 as a
+net-addition if rewritten on the primitive. Each keeps a dated `NOTE:` at the top recording that;
+re-open the question only when the primitive gains the missing behavior.
+
+## Routing
+
+`src/app/` is the Expo Router tree. Groups in parens (`(auth)`) don't affect
+the URL. Layouts (`_layout.tsx`) wrap their siblings. Typed routes are on, so
+links are type-checked against the file tree.
+
+For the full screen inventory, the sign-in and capture flows as diagrams, and
+the rules a routing change has to keep, see
+[App navigation flow](https://docs.cml-relab.org/architecture/app-flow/) in the
+docs site. This section stays as the in-tree summary.
+
+The three primary destinations are tabs: `(tabs)/(products)`,
+`(tabs)/(cameras)` and `(tabs)/(account)`, each a group holding its own Stack,
+so every tab keeps its trail while you are on another one. BottomNav is that
+navigator's `tabBar`. The products tab owns both the `/products` and
+`/components` trees — a component is a product's child, and cards, breadcrumbs
+and post-create redirects hop between them constantly; splitting them across
+navigators would make every hop a cross-navigator `replace`, which React
+Navigation resolves by swapping the whole tab navigator out and resetting every
+tab. For the same reason, a link that leaves one tab for another must use
+`navigate`, never `replace`. The root stack keeps only what sits outside the
+tabs: the entry redirect, `(auth)`, `category-selection` and `users/[username]`.
+
+Detail screens are anchored-scroll documents: sections self-register with
+SectionNavContext; chips (phone) / outline (lg web) navigate via
+useSectionNav.
+
+The account screen uses the same anchored-scroll document pattern. On web at
+lg and above, TopNav (src/components/base/TopNav.tsx) renders the persistent
+app bar from src/navigation/destinations.ts and the stack header is hidden for
+the screens it covers; phones keep the stack headers.
+
+Creation is capture-first: /products/new and components/new render
+CaptureScreen (photos/name/type), POST immediately, then land on the detail
+screen in edit mode.
+
+## Data Flow
+
+1. Runtime API helpers call the backend at `$EXPO_PUBLIC_API_URL`, appending `/v1` for application
+   routes.
+1. `just backend/openapi` exports the canonical schema to
+   [src/types/openapi.json](src/types/openapi.json); `just codegen` regenerates
+   [src/types/api.generated.ts](src/types/api.generated.ts) from it and runs
+   `scripts/redact_api.mjs` to strip JWT examples before commit.
+1. Request helpers live in [src/services/api](src/services/api); feature hooks
+   wrap them with TanStack Query, returning typed data.
+1. MSW handlers in `src/test-utils/` mock the same surface in unit/integration
+   tests so component code is identical in prod and test.
+
+Client-only state (wizard progress, transient UI) lives in feature-local
+hooks/reducers or React context. Server state stays in TanStack Query; don't
+mirror it into client state stores.
+
+### Picking an image size
+
+Read schemas carry `thumbnail_url` (the 200px list thumbnail) *and*
+`thumbnail_urls`, the API's pre-computed derivatives keyed by width — 200/800/1600, generated at
+upload, minus any width at or above the original, so the map is sparse. `resolveApiMediaUrlMap`
+resolves it through the same safety checks as any other media URL.
+
+Read schemas also carry `width_px`/`height_px` — the stored original's size after EXIF rotation,
+recorded at upload from the header the processor already parses. Every derivative is a scaled copy,
+so they all share that aspect ratio and each one's height follows from its width. Rows uploaded
+before the columns existed are null until
+`python -m scripts.maintenance.backfill_image_dimensions` measures them.
+
+With dimensions, the gallery pager hands expo-image a `source` **array** and lets it match the
+candidate to the container at the screen's scale — which becomes a real `srcset` on web. Without
+them a width-only array would leave that selection guessing, so `sourceSet` is empty and the
+explicit pick below takes over. The lightbox always picks explicitly: there, zoom decides the
+source, not the container.
+
+React Native has no `srcset`, so a view picks once from its own known layout:
+`pickThumbnailUrl(sources, layoutPt * PixelRatio.get())` takes the narrowest derivative that
+covers the need, or the widest there is. Where each surface lands today:
+
+| Surface                                          | Layout      | Source                                                                 |
+| ------------------------------------------------ | ----------- | ---------------------------------------------------------------------- |
+| `ComponentRow`, gallery filmstrip, `ProductCard` | 44–80pt     | `thumbnail_url` (200px) — already right at 3x                          |
+| Gallery pager                                    | full width  | picked in `useProductGalleryMedia`, ~1600px on a modern phone          |
+| Lightbox                                         | full screen | picked the same way, swapping to the original past `ORIGINAL_AT_SCALE` |
+
+`useProductGalleryMedia` is the single place the screen size is known, so it narrows `mediumUrl`
+and `largeUrl` there and every consumer downstream — pager, lightbox, prefetch — keeps reading the
+same two fields. Both tiers previously pointed at the raw upload, which is never downscaled on the
+way in, so opening a gallery pulled several megabytes per image and prefetched that for every
+image in the product.
+
+## Regenerating API Types
+
+The TypeScript API types are autogenerated from the backend OpenAPI schema and written to
+`src/types/api.generated.ts`.
+
+That generated OpenAPI output is the only supported frontend contract for the
+RPi camera integration. The private backend\<->plugin seam lives in the
+published `relab-rpi-cam-models` Python package and should not be imported or
+re-declared directly in frontend code.
+
+Codegen reads the committed `src/types/openapi.json` (exported by the backend
+via `just backend/openapi`), so no running backend is required:
+
+```bash
+# regenerate types from the committed schema, redact JWT examples, and format
+just codegen
+```
+
+## Common Commands
+
+```bash
+just check       # lint
+just test        # full Jest suite (unit + integration)
+just test-unit   # fast Jest unit tests
+just test-integration  # slower Jest integration tests
+just test-e2e    # Playwright browser E2E
+just test-ci     # CI-style Jest run with coverage
+just format      # format code
+just build-web   # export web build for E2E
+pnpm run lint:react            # strict React hooks/compiler + Fast Refresh ESLint pass
+pnpm run profile:compiler:web  # local web profiling with production/staging compiler transforms enabled
+```
+
+## Test Layers
+
+| Layer       | Tool             | Location                          | What it covers                                                    |
+| ----------- | ---------------- | --------------------------------- | ----------------------------------------------------------------- |
+| Unit        | Jest + jest-expo | `src/**/*.test.ts(x)`             | Pure logic, single component, MSW-mocked.                         |
+| Integration | Jest + jest-expo | `src/**/*.integration.test.ts(x)` | Multiple components wired together, realistic nav.                |
+| E2E         | Playwright       | `e2e/`                            | Full-stack against the built web export + docker-compose backend. |
+
+`just test` runs both Jest lanes. E2E requires `just build-web` and the `compose.e2e.yaml` stack.
+
+Jest integration tests run in-memory with `jest-expo` and React Native Testing Library. They are
+broader than unit tests, but they are not a substitute for device-native end-to-end coverage.
+
+**Location rule:** co-locate every Jest test in a `__tests__/` folder beside the
+code it covers; the Jest lane is chosen by the filename **suffix**, not the
+folder (`.integration.test.*` → integration lane, everything else → unit). The
+unit lane auto-mocks `expo-router` (see `config/setup.unit.ts`); the integration
+lane doesn't, so integration tests mock it locally. Root-level/cross-cutting
+tests with no single home (config, security policy, theme regressions) live in
+`src/__tests__/`.
+
+**E2E environmental failures (not code bugs):** `just test-e2e` needs the
+`compose.e2e.yaml` stack running against a clean database. A few known-failing
+specs are environmental, not regressions — do **not** edit specs to accommodate
+them:
+
+- **"Mine" empty-state / seeded-product-not-on-page-1** — the e2e Postgres has
+  accumulated test data. Fix by resetting/reseeding the e2e DB, not the spec.
+- **OAuth sign-in specs** — `compose.e2e.yaml` doesn't inject Google/GitHub OAuth
+  credentials, so those flows can't complete in CI-local runs.
+
+If a spec fails, first confirm the stack is up and the DB is freshly seeded
+before treating it as a code regression.
+
+## Timing Jest Suites
+
+To profile slow test files, run Jest with JSON output and inspect the report:
+
+```bash
+pnpm test -- --runInBand --json --outputFile=.jest-timings.json
+```
+
+## Styling And Theming
+
+Styling in `app` is built on Uniwind, with colors, type scale, and semantic tokens delivered
+through `AppThemeProvider` (see [Stack](#stack)). Uniwind reads `global.css` through its Metro
+plugin; theme variables live in `src/theme/brand.generated.css` as `@variant light`/`@variant dark`
+blocks, and `Uniwind.setTheme()` in `src/app/_layout.tsx` is what switches between them.
+
+- Import theme values from `@/theme`, not from `src/assets/themes/*`
+- Use `useAppTheme()` as the default hook for theme access
+- Prefer semantic tokens like `theme.tokens.status.live`, `theme.tokens.text.muted`, and
+  `theme.tokens.surface.accent` over raw hex or `rgba(...)` literals
+- Keep static layout in `StyleSheet.create()`
+- For theme-dependent styles, use small colocated factories like `createStyles(theme)`
+- Keep `src/app/` route-only; router helpers belong under `src/utils/router/`
+
+In practice, that means:
+
+- `src/theme/` is the only supported theme entrypoint
+- shared visual primitives should live under `src/components/base/`
+- new hard-coded color literals in app code should be treated as regressions unless they belong in
+  the theme layer, generated assets, or tests
+
+## React Performance Profiling
+
+Memoization changes in this app should be validated in a release-like build, not only in Metro dev
+mode.
+
+1. Run `pnpm run profile:compiler:web` to start Expo web with `ENVIRONMENT=production`, which keeps
+   the React Compiler enabled locally without changing the normal `dev` workflow.
+1. Open the app in a browser with React DevTools installed and record the interaction in the
+   Profiler tab.
+1. Confirm the slow interaction in the profiler before changing memoization.
+1. Re-profile after the change and keep manual `useMemo` / `useCallback` / `React.memo` only where
+   the compiled build still benefits.
+
+The default `pnpm run dev` flow keeps compiler transforms off for faster Metro feedback while you
+iterate.
+
+## Build And Deploy
+
+- **Dev (web):** `just dev`: Expo Metro on :8081.
+- **Dev (native):** `pnpm android` / `pnpm ios`.
+- **Web build:** `just build-web` runs `expo export -p web -c` → `dist/`.
+- **Runtime:** Caddy serves `dist/` with CSP templated from
+  `CADDY_API_ORIGIN`. The enforced policy keeps temporary Expo web allowances for
+  inline/eval script execution, permits product embeds only from
+  `https://www.youtube-nocookie.com`, and sends a stricter report-only policy as
+  the hardening target. See [Dockerfile](Dockerfile) and
+  [Caddyfile](Caddyfile).
+- **Native releases:** not containerised; use Expo's native build flow from a
+  developer machine.
+
+## Lint Ownership
+
+Biome is the primary formatter/linter for this app, including the React rules it supports:
+
+- hook ordering and dependency linting
+- React prop assignment safety
+- general React module/export safety where configured
+
+ESLint is intentionally narrow: it covers the React hooks and compiler checks that Biome does not
+handle, Fast Refresh export-only structure via `eslint-plugin-react-refresh`, and a small set of
+React Native accessibility rules via `eslint-plugin-react-native-a11y`. This overlap is deliberate;
+when Biome ships equivalents for these rules, remove ESLint and its plugins.
+
+The React ESLint pass is blocking, not advisory. `pnpm run lint:react` must pass with zero warnings.
+
+Key ESLint coverage includes:
+
+- `react-hooks/preserve-manual-memoization`
+- `react-hooks/static-components`
+- `react-hooks/config`
+- `react-hooks/gating`
+- `react-hooks/unsupported-syntax`
+- `react-hooks/globals`
+- `react-hooks/error-boundaries`
+- `react-hooks/set-state-in-render`
+- `react-refresh/only-export-components`
+- `react-native-a11y/*` accessibility prop checks (see `eslint.config.mjs` for the enabled rules)
+
+Beyond those accessibility rules, React Native-specific linting is intentionally minimal: Biome does
+not expose an RN-specific rule surface.

+/*
+  redact_api.mjs
+
+  Purpose: remove any example JWTs embedded by the OpenAPI -> TypeScript
+  generator from the generated frontend file `src/types/api.generated.ts`.
+
+  Why: some OpenAPI examples may contain real-looking tokens that trigger
+  gitleaks or other secret-scanning tools. This script performs a simple
+  regex replace to substitute such `access_token` example values with
+  the safe placeholder `<REDACTED_JWT>` so generated files are safe to
+  commit and publish.
+
+  Behavior:
+  - Locates `api.generated.ts` relative to the app subrepo.
+  - Replaces any value matching the pattern used for JWT-like strings
+    in `"access_token": "..."` with `"access_token": "<REDACTED_JWT>"`.
+  - Only writes the file if a change was made.
+
+  Usage:
+    # from app
+    pnpm run codegen:api:redact
+    # or directly
+    node scripts/redact_api.mjs
+*/
+const main = () => {
+  const file = resolve('src', 'types', 'api.generated.ts');

+  // missing file surfaces as ENOENT here.

+/**
+ * Local direct-connection mode for RPi cameras.
+ *
+ * When a camera is physically connected to the same machine via Ethernet or a
+ * USB-C to Ethernet adapter, the frontend can bypass the backend WebSocket relay
+ * and talk directly to the Pi's FastAPI (:8018). Preview media is served from
+ * that same port (the Pi proxies MediaMTX, which binds to loopback only).
+ *
+ * Benefits:
+ *  - LL-HLS preview latency drops from ~1.5–3 s to ~0.4–0.8 s
+ *  - Works with no internet connection
+ *  - Lower backend bandwidth usage
+ *
+ * The relay connection on the Pi keeps running in parallel, so remote users
+ * accessing the same camera via the backend continue to work unchanged.
+ *
+ * ## Auto-configuration (medium-term / zero-copy setup)
+ *
+ * When the camera is online, the hook fetches local access info through the
+ * relay (GET /cameras/{id}/local-access → Pi's /system/local-access). The Pi
+ * returns its API key and all its LAN IP addresses. The hook probes each
+ * candidate URL in parallel against the Pi's unauthenticated `/healthz`; the
+ * first that answers as an RPi cam is then checked once with the device key,
+ * which is what proves it is *this* camera (`/healthz` carries no identity).
+ * Only after that is the URL/key pair persisted and local mode activated — no
+ * manual key copying required, and the key reaches at most one candidate.
+ *
+ * If the camera is offline or the relay call fails, the hook falls back to
+ * any previously-stored URL/key or the USB gadget default address. Users can
+ * still configure manually via the returned `configure()` function.
+ *
+ * Usage:
+ *   const conn = useLocalConnection(cameraId, { isOnline });
+ *   // conn.mode: 'probing' | 'local' | 'relay'
+ *   // conn.localBaseUrl, conn.localApiKey populated when mode === 'local'

+ * `inverseSurface` is the dark-on-light / light-on-dark ground used by

+ * 1.16:1 in light: the product name was invisible in both schemes, and the

+# R9lab Design System
+
+Source of truth for brand typography and colour across the monorepo.
+Web/email primitives live in [brand.css](brand.css); the app maps the same
+palette through its MD3 theme in `app/src/theme/`. Edit here, then run
+`just assets-sync`.
+
+Direction: **Cyanotype & Manila** — the colour of engineering documentation.
+Before a product can re-enter the loop, someone has to document how it was
+made; cyanotype blue is the colour of that record, manila the tag tied to the
+part. An alternative direction (Verdigris & Copper) is preserved
+[below](#alternative-direction--verdigris--copper); open
+[design-compare.html](design-compare.html) for a side-by-side view of both.
+
+## Typography — IBM Plex superfamily
+
+Three voices, one family:
+
+| Role            | Face                  | Usage                                         |
+| --------------- | --------------------- | --------------------------------------------- |
+| Display / brand | IBM Plex Serif 600    | Headings on www/docs, logo letters, og-images |
+| UI / body       | IBM Plex Sans 400–600 | Everything else on web and email              |
+| Data / labels   | IBM Plex Mono 400     | Measurements, IDs, small data labels, code    |
+
+Type scale (web): display 38/44, title 24/30, heading 19/24, body 16/26, label 13 caps
+(+0.1em tracking, weight 400), caption 13/18, micro 12/16, data 14 mono with `tabular-nums`. Docs maps
+this scale onto Starlight's `--sl-text-h1/h2/h3` tokens; www sets it directly. The app
+adds an `eyebrow` variant — label metrics, rendered uppercase, muted (or accent) ink for
+compact tags — and caps Dynamic Type scaling app-wide at 2x so fixed layouts survive
+large accessibility text sizes. That variant is app-only: see the accent rules
+[below](#colour--type-roles-within-the-form) for why the web surfaces carry no eyebrows.
+
+The **Expo app intentionally stays on platform system fonts** (native feel,
+Dynamic Type, zero load cost). The app adopts the *scale and palette*, not the
+typeface. WOFF2 files in [fonts/](fonts/) are latin subsets for docs/www
+delivery; italic is browser-synthesized.
+
+## Colour — Cyanotype & Manila
+
+All pairings below meet WCAG 4.5:1 against their background in both schemes.
+
+| Token           | Light     | Dark      | Role                                                                                    |
+| --------------- | --------- | --------- | --------------------------------------------------------------------------------------- |
+| primary         | `#1F4C96` | `#8FB8FF` | Brand anchor, actions, links on web                                                     |
+| primary-strong  | `#143567` | `#BAD3FF` | Hover/pressed, emphasis                                                                 |
+| accent          | `#8F6212` | `#E3B95C` | Manila — highlights, live indicators, strategy tags                                     |
+| text            | `#16202E` | `#E2E6EE` | Body text (app; web uses `#E9EFF8` via --relab-brand-text)                              |
+| mutedForeground | `#44474F` | `#C4C6D0` | Secondary text (www's `--color-muted` in tokens.css is a distinct page-chrome override) |
+| muted           | `#E0E2EC` | `#44474F` | Muted surface tone behind secondary content                                             |
+| background      | `#FAFBFE` | `#11141D` | Page ground                                                                             |
+| surface         | `#F0F3FA` | `#1A2030` | Cards, panels                                                                           |
+| border          | `#C4C6D0` | `#44474F` | Hairlines, dividers (web uses `#D9DFE8`/`#24314A` via --relab-brand-divider)            |
+
+The machine sources are `brand.css` (web), `palette.json` (app), and `tokens.json` (the radius,
+shadow, type and chart tables below); this table documents them and is checked by
+`app/src/theme/__tests__/palette-sync.test.ts`.
+
+The prose names above and the JSON keys are two vocabularies — `primary-strong`/`primaryStrong`,
+`text`/`foreground`, `surface`/`card` — reconciled by the `BRAND_PARITY` table in
+`scripts/sync_brand_assets.py`. `palette.json` also carries `secondary`, `state`, `destructive`
+(`#BA1A1A`), `input` and `ring`, which this table does not restate.
+
+Web consumes these as `--relab-brand-*` custom properties (see brand.css).
+The app derives its MD3 colour roles from the same anchors: `primary` maps to
+the MD3 primary pair, `accent` to tertiary, neutrals to the blue-biased
+surface/outline ramp in `app/src/theme/themes.ts`.
+
+Status colours (success/warning/danger/info/live) are app-semantic, not brand,
+and stay as defined in `app/src/theme/tokens.ts` as scheme-aware light/dark
+pairs, contrast-tested at 4.5:1 against the page background and (for solid
+fills) against their own `onStatus` text — see `semantic-contrast.test.ts`.
+`live` wears the manila accent rather than a semantic hue: the small
+live/status pill is the one sanctioned manila fill. `info` and `link` blues
+sit near the new primary by design — blue-primary apps read links as primary
+actions.
+
+### Diagram & chart palette
+
+Categorical ramp for mermaid diagrams (`docs/src/content/docs/architecture/`),
+the www stats chart, and future app charts. Blue and manila come straight from
+the brand; verdigris and copper are borrowed from the alternative direction
+below; violet, rose, and slate round out the seven roles the diagrams need.
+The same category always wears the same hue across diagrams.
+
+| Hue             | Fill      | Stroke    | Text      |
+| --------------- | --------- | --------- | --------- |
+| Blue (primary)  | `#E3ECFA` | `#1F4C96` | `#143567` |
+| Manila          | `#F7ECD4` | `#8F6212` | `#5C3F0A` |
+| Verdigris       | `#E0F2ED` | `#0E6B5E` | `#0A4F45` |
+| Copper          | `#F9E7DE` | `#A8542F` | `#6E371F` |
+| Violet          | `#EDE6F7` | `#6D4FA3` | `#44337A` |
+| Rose            | `#FAE4EC` | `#B0316E` | `#6E2048` |
+| Slate (neutral) | `#F1F4F8` | `#5A6675` | `#16202E` |
+
+Solid single-hue marks (the www activity bars) use the primary brightened into
+the data-viz band — `light-dark(#2f6bc7, #6fa8ff)` — because the brand blues
+are tuned for text/links, not large fills. If the palette direction ever
+changes, this table and `--color-chart-mark` in `www/src/styles/tokens.css`
+are the only places to update.
+
+## Form language — Flat & Sharp
+
+The palette and type above set the brand; this sets the **shape**. Direction:
+**flat & sharp** — the geometry of an engineering document. It replaces the
+MD3/Paper-era look (pill buttons, ambient drop shadows, oversized radii) the
+app carried over from its react-native-paper origins. It reads crisp/technical
+on desktop and stays ergonomic on mobile.
+
+### Radius
+
+| Token            | Value | Applies to                                 |
+| ---------------- | ----- | ------------------------------------------ |
+| `radius-control` | 6px   | buttons, inputs, chips, segmented controls |
+| `radius-card`    | 8px   | cards, panels, list rows                   |
+| `radius-overlay` | 12px  | dialogs, bottom sheets, menus, FAB         |
+| `radius-full`    | 9999  | avatars, true pills only                   |
+
+Large surfaces stay a step softer than small controls, so sharp corners never
+read brittle on a phone. In the app these map through `app/src/constants.ts`.
+
+### Elevation — flat base, one floating tier
+
+Inline surfaces (cards, rows, inputs) are **flat**: a 1px hairline `border` +
+`surface` fill, **no shadow**. Shadow is reserved for surfaces that actually
+float, as a single tier:
+
+| Token            | Light                           | Dark                         | Use                                    |
+| ---------------- | ------------------------------- | ---------------------------- | -------------------------------------- |
+| `shadow-overlay` | `0 8px 24px rgba(20,40,80,.16)` | `0 8px 24px rgba(0,0,0,.55)` | menus, dialogs, sheets, FAB, snackbars |
+| `scrim`          | `rgba(12,18,32,.50)` (45–55%)   | `rgba(0,0,0,.55)`            | behind modals / sheets                 |
+
+Android takes a native elevation instead of the web shadow: `elevationAndroid` in `tokens.json`,
+8 light / 12 dark.
+
+This single tier removes the "everything floats" MD3 tell while keeping
+overlays legible on mobile.
+
+### Density, touch, motion
+
+- **Touch floor 44/48px**, 8px minimum gaps, 4/8px spacing rhythm. Sharpness
+  comes from tighter section spacing and hairlines, never smaller tap targets.
+- **Motion is functional**: 150–300ms, ease-out entering, exits as faster
+  plain fades (shorter than their entrance); press feedback via
+  opacity/state-layer with no layout shift; overlays animate from their
+  trigger; `prefers-reduced-motion` respected.
+- **Dark mode in parity**: desaturated tonal surfaces, borders visible in both
+  schemes, scrim strong enough to isolate overlays.
+
+### Icons — Lucide
+
+One icon family: **`lucide-react-native`** — consistent 2px stroke, sharp
+corners, outline style throughout. It is the technical/blueprint counterpart to
+the flat-&-sharp geometry, replacing the mixed-weight `@expo/vector-icons`
+(MaterialCommunityIcons) set. Sizes are tokens (`icon-sm` 16, `icon-md` 20,
+`icon-lg` 24); icon-only controls keep a ≥44px hit area.
+
+Brand marks are the one exception: GitHub, Google, YouTube, and LinkedIn are
+vendored monochrome SVGs in `assets/icons/brand/` (Simple Icons, CC0-1.0),
+rendered filled with `currentColor` at the same size tokens as Lucide glyphs.
+Lucide stays the only family for non-brand glyphs; never recolor a brand mark
+into its own brand palette.
+
+### Colour & type roles within the form
+
+Primary blue carries **all interaction** — actions, links, and every
+hover/pressed/selected state. Interaction states use a subtler shade of the
+primary (`primary-strong` for filled controls; a primary tint / state-layer for
+ghost/tonal/outline buttons) — **never the accent.** `tokens.surface.accent`
+(primary at 12% opacity) is the canonical selected/tinted fill — chips, history
+rows, toggles. MD3's `*Container` roles are retired from app call sites in
+favour of it.
+
+The **manila accent is a data-label colour** — R-numbers, record IDs, small data
+highlights, live/status pills, and strategy tags. It marks a *datum*, never a
+section. Decorative kickers above a heading are not a use for it, and on the web
+they are not a use for anything: a mono uppercase label that only restates the
+heading under it is chrome, so www and docs carry no eyebrows at all. The app's
+`AppText variant="eyebrow"` stays, because there it labels a value inside a
+compact tag rather than announcing a section.
+
+The accent never fills a button or drives a hover/pressed state. Lean on the mono
+voice (IBM Plex Mono on web, platform monospace in the app) for IDs, counts, and
+measurements — the "lab instrument" register.
+
+**Accent is for small text, never for mass.** Bars, big figures, and other
+large elements stay ink — including single-series chart bars and the hero/tile
+stat numbers. Manila reads as a highlight because it is scarce and small; at
+size it competes instead of accenting. When in doubt on something large, use
+ink. (In the categorical diagram ramp above, manila encodes a category rather
+than emphasis, so these size rules do not apply there.)
+
+Dialogs: destructive actions render filled-destructive; keyboard submit never
+targets a destructive or cancel action.
+
+## Logo
+
+The mark is a **font-derived 9, vertically squished** so it reads as a loop
+(and as a mirrored "e" — the wordmark whispers "Relab"). Letters are IBM Plex;
+the flask emblem is retired, replaced by a plain ring in the ringed lockup.
+Three candidate fonts for the 9 are generated side by side; **Titillium** is
+the promoted canonical mark (was Varela), with Petrona and Varela kept as
+alternates in `logo-src/candidates/` — see [logo-src/](logo-src/README.md).
+Promote another via `make_r9lab.py --promote <name>` + `just assets-sync`.
+Colours
+follow the palette above; og-images and all PNG derivatives regenerate from
+the same pipeline.
+
+## Voice
+
+The brand is always read and pronounced **"Relab"**, and that is how it is
+written in running copy, alt text, and aria-labels. The `R9lab` spelling is a
+purely visual device — the squished 9 reads as a mirrored "e" while hinting at
+the 9R framework of circular-economy strategies (the framework itself spans
+R0–R9) — and lives only in the wordmark artwork itself. Never "R-nine-lab".
+
+Circularity framing, lab vernacular (products, components, materials,
+samples); never "reverse engineering" in new copy.
+
+## Alternative direction — Verdigris & Copper
+
+Runner-up palette, kept as a fallback pending supervisor review; typography is identical.
+Story: copper is the most recovered material in the industrial stream, and
+verdigris is what it wears when it comes back. The green-teal primary is a
+half-step from the original teal (`#006783`) — lowest migration cost of the
+directions considered. All pairings meet WCAG 4.5:1 in both schemes.
+
+| Token          | Light     | Dark      | Role                                 |
+| -------------- | --------- | --------- | ------------------------------------ |
+| primary        | `#0E6B5E` | `#5FD4BE` | Brand anchor, actions                |
+| primary-strong | `#0A4F45` | `#9CE8D8` | Hover/pressed, emphasis              |
+| accent         | `#A8542F` | `#E89C77` | Copper — highlights, live indicators |
+| text           | `#14231E` | `#E8F2EC` | Body text                            |
+| muted          | `#5C6B65` | `#8FA39A` | Secondary text                       |
+| background     | `#F6F9F7` | `#0D1613` | Page ground                          |
+| surface        | `#FFFFFF` | `#15211C` | Cards, panels                        |
+| border         | `#D8E2DC` | `#263831` | Hairlines, dividers                  |
+
+Drop-in `brand.css` block if this direction is adopted:
+
+```css
+:root {
+  --relab-brand-primary: light-dark(#0e6b5e, #5fd4be);
+  --relab-brand-primary-strong: light-dark(#0a4f45, #9ce8d8);

+# Shared Brand Assets
+
+This directory is the source of truth for the shared Relab brand assets
+used across the monorepo.
+
+Edit the files here, then run:
+
+```bash
+just assets-sync
+```
+
+That regenerates the consumer copies in `app/`, `docs/`, `www/`, and
+`backend/`. Do not hand-edit copied consumer files unless the sync mapping
+itself changes. Use:
+
+```bash
+just assets-check
+```
+
+to verify that committed consumer files still match the canonical sources.
+
+The logo is the R9lab mark — a font-derived, vertically squished 9 — generated
+from the sources in [logo-src/](logo-src/README.md). `r9lab-logo.svg` is the
+wide ringed wordmark; square favicons and app icons render from
+`r9lab-mark.svg`.
+
+The sync script uses ImageMagick (`magick`, or `convert` on IMv6) to generate
+the PNG and `.ico` derivatives from the SVG sources.
+
+Current shared assets:
+
+- `brand.css`
+- `images/bg-light.jpg`
+- `images/bg-dark.jpg`
+- `r9lab-*.svg` / `r9lab-*.png` — mark, logo, wordmark, and og-image variants,
+  light and dark (see [logo-src/](logo-src/README.md))
+- `fonts/ibm-plex-*.woff2`
+- `icons/brand/{github,google,youtube,linkedin}.svg` — monochrome brand marks
+  (Simple Icons, CC0-1.0); `just assets-sync` copies them to
+  `docs/src/assets/icons/brand/` and `www/src/assets/icons/brand/`.
+
+Typography ownership (see [DESIGN.md](DESIGN.md) for the full design system):
+
+- The IBM Plex superfamily is the custom web/email typeface: Sans
+  (`--relab-brand-font`, UI/body), Serif (`--relab-brand-font-display`,
+  display/brand), Mono (`--relab-brand-font-mono`, data/labels).
+- WOFF2 files are for docs/www web delivery; italic is browser-synthesized when needed.
+- The Expo app uses platform system fonts (see [DESIGN.md](DESIGN.md)).
+
+Brand primitive ownership:
+
+- `brand.css` owns web font declarations and light/dark brand color anchors.
+- Synced CSS exposes brand variables as `--relab-brand-*` for docs and www.
+- Consumer subrepos keep layout, spacing, component styles, shadows, radii, and
+  app-specific theme behavior local.
+
+Generated consumer output groups:
+
+- Background images: copied to the app, docs, and www image asset folders.
+- Regular IBM Plex Sans web fonts: copied to the docs and www `public/fonts` folders.
+- Brand CSS: copied to docs and www style folders.
+- SVG logos, wordmarks, and favicons: copied from the `r9lab-*` SVGs to docs and www public image
+  folders; favicons use the square mark.
+- PNG outputs: generated for Expo app metadata, the www social preview logo, and docs/www Apple
+  touch icons.
+- `.ico` fallback favicons: generated at the docs/www public root for legacy browser support and in
+  backend static storage for `/favicon.ico` support.
+- Brand icon SVGs: copied from `icons/brand/` to the docs and www icon asset folders.

+# r9lab logo — source & generators
+
+The mark is a **font-derived 9, vertically squished** so it reads as a loop (a
+mirrored "e" — the wordmark quietly says "Relab"). The R/l/a/b letters come
+from IBM Plex. Output SVGs are self-contained — glyphs are outlined, so no
+font is needed to render them. Colours are the Cyanotype palette from
+[../DESIGN.md](../DESIGN.md): `#1f4c96` light / `#8fb8ff` dark for the 9 and
+ring, ink `#16202e` / `#e9eff8` for the letters.
+
+## Generate
+
+Needs [`uv`](https://docs.astral.sh/uv/). Run from this directory:
+
+```sh
+# regenerate every candidate set into candidates/<name>/
+uv run --with fonttools --with brotli python3 make_r9lab.py
+
+# additionally copy one candidate onto the canonical ../r9lab-*.svg + ../logo.svg
+uv run --with fonttools --with brotli python3 make_r9lab.py --promote titillium
+```
+
+After promoting, run `just assets-sync` from the repo root to regenerate the
+PNG/ico derivatives and consumer copies.
+
+## Candidates
+
+Three candidate fonts for the 9; **titillium** is the promoted canonical mark,
+with petrona and varela kept as alternates. Tuned values live in `CANDIDATES`
+in `make_r9lab.py`:
+
+| Candidate   | 9 from            | Letters            | Notes                             |
+| ----------- | ----------------- | ------------------ | --------------------------------- |
+| `varela`    | Varela 400        | IBM Plex Sans 500  | outline-stroked to fake a 500 cut |
+| `petrona`   | Petrona 600       | IBM Plex Serif 600 | serif-blend variant               |
+| `titillium` | Titillium Web 600 | IBM Plex Sans 600  |                                   |
+
+Each `candidates/<name>/` holds light + `-dark` SVGs for five variants:
+
+| File            | What                                                |
+| --------------- | --------------------------------------------------- |
+| `mark.svg`      | the squished 9 alone — favicons, app icons          |
+| `mark-ring.svg` | the 9 in a plain ring (loop emblem)                 |
+| `wordmark.svg`  | pure-text `R9lab` lockup                            |
+| `logo.svg`      | ringed wordmark — `(R9) lab`, the primary wide logo |
+| `og.svg`        | 1200×630 social card (wordmark + tagline)           |
+
+Promoting only copies SVGs; every PNG/ico derivative (consumer copies, the
+canonical `../r9lab-*.png` companions the root README embeds, and the og
+cards) is rendered by `scripts/sync_brand_assets.py` — hence the
+`just assets-sync` step.
+
+Font subsets (latin) are checked in under `fonts/candidates/` with their OFL
+licence texts (`OFL-*.txt`).

+# Product screenshots
+
+**These images show seeded demonstration records, not real teardowns.**
+
+Everything visible here — "Dell XPS 13", "iPhone 12", their brands, dimensions, owners and
+photos — comes from the test fixture at `backend/data/seed/dummy_data.json`, loaded into a
+throwaway E2E database. The accounts (`relab_demo` / `e2e-admin@example.com`, `alice`, `bob`)
+are test accounts. No record in these screenshots describes a product anyone actually
+disassembled, weighed or measured.
+
+Use them only to show what the interface looks like: READMEs, docs, slides about the software,
+issue reports. **Never** use them as evidence of research output, dataset contents, coverage or
+results, and never place them where a reader could reasonably take them for real data. If a
+figure needs real teardown data, capture it from real records and say so.
+
+Captured: **2026-08-18**.
+
+## Files
+
+20 PNGs, named `<surface>-<width>-<scheme>.png`:
+
+| Surface               | What it shows                            |
+| --------------------- | ---------------------------------------- |
+| `products`            | The product list, welcome card dismissed |
+| `product-detail`      | "Dell XPS 13" in view mode               |
+| `product-detail-edit` | The same record with `?edit=1`           |
+| `product-new`         | The capture screen at `/products/new`    |
+| `account`             | The account screen                       |
+
+Widths `390` (mobile, 390x844 viewport) and `1440` (desktop, 1440x900 viewport), each in
+`light` and `dark`. Pages whose content is taller than the viewport were captured with the
+viewport extended to the full content height, so those files are taller than 844/900 px.
+
+`product-new` is a viewport-height capture: the screen fits without scrolling.
+
+**What is here, and why only six.** These regenerate in one command (below), so the committed
+set is deliberately small rather than a full matrix — every PNG is permanent weight in git
+history. Six cover the ground that matters:
+
+| File                        | Why it earns a place                                                           |
+| --------------------------- | ------------------------------------------------------------------------------ |
+| `products-390-light`        | The app's home on the primary form factor                                      |
+| `products-390-dark`         | Dark mode is a stated design principle, not an afterthought; this is the proof |
+| `products-1440-light`       | The `lg` chrome swap — persistent top bar, multi-column grid                   |
+| `product-detail-390-light`  | The Spec Row, the app's signature pattern                                      |
+| `product-detail-1440-light` | The `lg` detail layout: section outline column instead of chips                |
+| `product-new-390-light`     | The capture screen — the product's core act                                    |
+
+Regenerate any other combination (account, edit mode, the 1440 dark variants) with the steps
+below rather than committing them.
+
+**Known limitation of tall captures.** Extending the viewport to content height moves anything
+positioned fixed or sticky — the save FAB, the docked save bar, the offline banner — to the
+bottom of the *expanded* frame rather than where a user would see it. If the position of floating
+chrome matters, use a viewport-height capture.
+
+**Two caveats about the seeded content.** "Dell XPS 13" has no photo in the fixture, so the detail
+hero shows a placeholder; "iPhone 12" is the seeded record that has one. And the signed-in test
+account owns nothing, so any account view reads `0 PRODUCTS / 0 PHOTOS`.
+
+## Regenerating
+
+From the repository root:
+
+```bash
+just _e2e-backend-up                 # Postgres + Redis + API, seeded from dummy_data.json
+just app/build-web                   # static Expo web export into app/dist
+cd app && pnpm exec serve dist -l 18011 --single --no-clipboard
+```
+
+Read the port from the server's own stdout — `serve` silently falls back to a random port when
+it cannot bind. Use `localhost`, never `127.0.0.1`: the session cookie is `SameSite=Lax` and is
+dropped cross-site (see `app/playwright.config.ts`).
+
+Then drive Chromium with Playwright: sign in with the seeded credentials in `app/e2e/helpers.ts`,
+dismiss the products welcome card, and screenshot each surface at both viewports with
+`colorScheme` set to `light` and `dark` (the app's theme mode defaults to `auto`, which follows
+`prefers-color-scheme`).
+
+Tear the stack down when finished:
+
+```bash
+docker compose -p relab_e2e -f compose.e2e.yaml down -v --remove-orphans
+```

+The backend provides the API, authentication flows, product and component data model, media

+[FastAPI](https://fastapi.tiangolo.com/), PostgreSQL, Redis, and `uv`.
 
 ## Quick Start
 
 ```bash
 just install
-cp .env.dev.example .env.dev
-./scripts/local_setup.sh
+cd .. && just deploy-secrets-template dev && just dev-db && just dev-migrate
+cd backend
 just dev
 ```
 
-The API is then available at <http://localhost:8000>.
+The API is then available at <http://127.0.0.1:8010>. Use Docker Compose for local PostgreSQL and
+Redis. Redis is required at backend startup and backs auth, rate limiting, runtime relay state, and
+endpoint caching. Create `.env.dev` only when you need backend-only non-secret overrides; local
+backend secrets live in `../secrets/dev/`.

-Taxonomy imports are intentionally opt-in for the migrations image. If you want `SEED_CPV_*` or `SEED_HS_CATEGORIES`, rebuild `backend/Dockerfile.migrations` with `BACKEND_MIGRATIONS_INCLUDE_TAXONOMY_SEED_DEPS=true` so the optional `seed-taxonomies` dependency group is available.
+`dummy_data.json` seeds one full teardown: the Dell XPS 13 carries a nested component tree and a
+photograph per part, which is what gives dev and CI a product whose parts have images at all. Seed
+photographs must stay wider than 800px — `generate_thumbnails` skips any width at or above the
+original's, so a narrower file yields the 200px derivative alone and every consumer loses its
+`srcset`. [tests/integration/db/test_dummy_seed.py](tests/integration/db/test_dummy_seed.py) holds
+that line.
 
-The main [`backend/Dockerfile`](Dockerfile) is multi-target: the default `runtime` stage builds the slim production image, and `--target dev` produces the hot-reload dev image used by `compose.dev.yaml`.

-## Current Backend Shape
+The main [`backend/Dockerfile`](Dockerfile) is multi-target: the default `runtime` stage builds the
+slim production image, and `--target dev` produces the hot-reload dev image used by
+`compose.dev.yaml`.
 
-The backend is intentionally moving toward explicit, domain-owned seams instead of broad internal registries.
+## Backend Architecture
 
-- Routers should stay thin orchestration layers.
-- Domain read paths should prefer small local `select(...).where(...)` helpers over generic query-builder indirection.
-- The shared CRUD/query kernel is intentionally small: keep `require_model`, `require_models`, `page_models`, `exists`, and persistence helpers. Older convenience helpers such as `QueryOptions`, `build_query`, and `list_models` are retired.
-- Recursive endpoints such as `/products/tree` and `/categories/tree` remain supported public APIs, but they should use bounded tree loaders plus pure serialization, never lazy ORM traversal during response assembly.
+The backend uses explicit, domain-owned seams rather than broad internal registries.
 
-Two examples of the preferred shape:
+- Routers are thin orchestration layers.
+- Domain read paths use small local `select(...).where(...)` helpers rather than generic
+  query-builder indirection.
+- The shared CRUD/query kernel is small: `require_model`, `require_models`, `page_models`, `exists`,
+  and persistence helpers.
+- Recursive endpoints such as `/v1/categories/tree` and `/v1/products/{product_id}/components/tree`
+  use bounded tree loaders plus pure serialization, not lazy ORM traversal during response assembly.
+- Query parameters stay in SQLAlchemy expressions so user values become bind parameters. Dynamic
+  identifiers such as sort or facet fields go through explicit allowlists before SQL is built. Raw
+  SQL stays static; runtime values are bound separately.
 
-- `app/api/data_collection/crud/products.py` is now the stable product-domain entrypoint, with tree reads in `product_tree_queries.py` and mutations in `product_commands.py`.
-- `app/api/file_storage/crud/` is split by concern; avoid reintroducing a broad `file_storage.crud` compatibility surface.
+Key reference points for the domain shape:
+
+- Product reads live in `app/api/data_collection/routers/product_read_routers.py`, tree queries in
+  `crud/product_tree_queries.py`, and mutations in `crud/product_commands.py`.
+- `app/api/file_storage/crud/` is split by concern.
 
 ## RPi Camera Contract Boundary
 
-The Raspberry Pi camera integration has two intentional contract layers:
+The Raspberry Pi camera integration has two contract layers:
 
 - **Public/frontend contract**: backend routes and OpenAPI remain the only app-facing API surface
-- **Private device seam**: `relab-rpi-cam-models` owns the backend\<->plugin transport DTOs for pairing, relay envelopes, local-access bootstrap, and direct upload acknowledgements
+- **Public device/plugin contract**: `/openapi.device.json` documents the supported device
+  integration surface, with the human reference hosted by the docs site
+- **Private device seam**: `relab-rpi-cam-models` owns the backend\<->plugin transport DTOs for
+  pairing, relay envelopes, relay allowlist policy, local-access bootstrap, and direct upload
+  acknowledgements
+
+Frontend code should keep consuming backend-generated OpenAPI types rather than importing private
+device-seam DTOs directly.
+
+## Email Delivery
+
+Transactional email templates are authored as MJML in
+[app/templates/emails/src/](app/templates/emails/src/) and compiled to committed HTML templates in
+[app/templates/emails/build/](app/templates/emails/build/):
+
+```bash
+just compile-email
+```
+
+Runtime code should send mail through `app/api/auth/services/email/`. Templates are rendered once
+before provider dispatch, so SMTP and Microsoft Graph receive the same internal message shape.
+
+### Google SMTP / Workspace SMTP Relay
+
+Use the default provider:
+
+```env
+EMAIL_PROVIDER=smtp
+SMTP_HOST=smtp.gmail.com
+SMTP_USERNAME=sender@example.com
+EMAIL_FROM=Relab <sender@example.com>
+EMAIL_REPLY_TO=relab@example.com
+```
+
+Store the SMTP password in `../secrets/<env>/smtp_password`. For a personal/free Google account, use
+an app password when available. For Workspace, prefer the Workspace SMTP relay when the domain
+policy allows it. Keep SPF, DKIM, and DMARC aligned for the sending domain. Google references:
+[send email with SMTP](https://support.google.com/a/answer/176600) and
+[email authentication](https://support.google.com/a/answer/10583557).
+
+### Microsoft Entra + Graph
+
+Use Graph when sending from a Microsoft 365 mailbox:
+
+```env
+EMAIL_PROVIDER=microsoft_graph
+EMAIL_FROM=Relab <relab@example.edu>
+EMAIL_REPLY_TO=relab@example.edu
+MICROSOFT_GRAPH_TENANT_ID=00000000-0000-0000-0000-000000000000
+MICROSOFT_GRAPH_CLIENT_ID=00000000-0000-0000-0000-000000000000
+MICROSOFT_GRAPH_SENDER_USER=relab@example.edu
+```
+
+Store the Graph client secret in `../secrets/<env>/microsoft_graph_client_secret`. Create a
+dedicated mailbox, register an Entra app, grant Microsoft Graph application permission `Mail.Send`,
+and restrict the app to that mailbox with an application access policy before production use.
+Microsoft references:
+[send mail with Graph](https://learn.microsoft.com/en-us/graph/api/user-sendmail),
+[client credentials](https://learn.microsoft.com/en-us/entra/identity-platform/v2-oauth2-client-creds-grant-flow),
+and
+[application access policies](https://learn.microsoft.com/en-us/graph/auth-limit-mailbox-access).
 
-Frontend code should keep consuming backend-generated OpenAPI types rather than importing private device-seam DTOs directly.
+Recurring newsletter delivery is not part of the runtime API. Any future implementation requires a
+real sender workflow, unsubscribe handling, and preference-center support before it should be wired
+into the API.

+"""Split base products and components at the DB level.
+
+Base products and components share the ``product`` table, discriminated by
+``parent_id``. Before this migration the role distinction was enforced only
+in application code.
+
+After this migration:
+- Base products have ``parent_id IS NULL`` and ``amount_in_parent IS NULL``.
+- Components have    ``parent_id IS NOT NULL`` and ``amount_in_parent IS NOT NULL``.
+A CHECK constraint enforces the role shape. ``owner_id`` remains NOT NULL on
+every row (components denormalize their root base product's owner so
+ownership checks, stats, and per-owner listings stay O(1) with existing
+indexes); Pydantic read schemas decide which role's fields get exposed.

-(PKCE, no backend redirect required) and exchange them for app sessions.
-
-Currently supported:
-  POST /auth/oauth/google/bearer/token  — returns bearer + refresh tokens
-  POST /auth/oauth/google/cookie/token  — sets httpOnly session cookies
-
-GitHub keeps using the backend-mediated flow (its OAuth token exchange requires
-a client secret and cannot be done client-side).

+"""Revocable opaque access tokens.
+
+fastapi-users' :class:`RedisStrategy` stores each access token as its own Redis key
+holding a bare user id, with no issue time and no user -> token index. So a global
+revocation ("log out all devices", password reset, deactivation, refresh-token reuse)
+can only reach *refresh* tokens; every already-issued access token stays valid until it
+expires on its own. That violates ASVS V7.4.1 and — for the deactivate/delete paths —
+V7.4.2, which is Level 1.
+
+This module makes access tokens revocable by stamping each one with an issue time and
+recording a per-user revocation epoch: a token is refused when it was issued before the
+epoch. Compared with keeping a per-user set of live tokens, this is O(1) to revoke and
+has no enumerate-then-delete race, which is the pattern used by e.g. Firebase's
+``tokensValidAfterTime`` and Django's session auth hash.
+
+The epoch lives in Redis rather than on the user row deliberately: losing Redis also
+loses every access token it governs, so the failure mode is fail-closed, and keeping it
+here means the Redis-only refresh-reuse path can revoke without a database session.

+The stored entry also carries a hash of the request body, so reusing a key for a *different*

 """Shared utilities for PostgreSQL full-text (tsvector) and trigram search.

---------------------------
+Usage in a filter class
+-----------------------
 1.  Add a ``search_vector`` computed column to the model (see
     ``app.api.data_collection.models.Product`` for the pattern).
-2.  Subclass ``TSVectorSearchMixin`` *before* ``Filter`` in the MRO.
-3.  Implement ``_search_vector_col`` and ``_trigram_cols`` as classmethods.
-4.  Remove ``search_model_fields`` from the inner ``Constants`` class so
-    fastapi-filter does not generate its own ILIKE queries for ``search``.
+2.  Implement ``search_vector_column`` and ``trigram_columns`` on the filter class.
+3.  Let ``app.api.common.crud.filtering`` apply the search clause.
 
 Example:
-    class MyFilter(TSVectorSearchMixin, Filter):
-        search: str | None = None
-        order_by: list[str] | None = None

 ## Recommended Baseline Inputs
 
 - Use `just docker-ci-perf-baseline` so the database is seeded with stable sample products before the k6 run starts.
-- `live_probe` and `product_tree_read` are the baseline scenarios and should always remain runnable.
-- `resized_image` is opportunistic rather than required. The Docker CI helper will try to discover a usable image automatically, but the baseline must still run cleanly if no image is available.
-- Use `/products/tree?recursion_depth=2` as the default product-read baseline unless you intentionally want a deeper tree.
+- `live_probe` and `product_list_read` are the baseline scenarios and must stay runnable.
+- `media_url_read` is opportunistic rather than required. The baseline must still run cleanly if no media URL is provided.
+- Use `/v1/products?size=20` as the default product-read baseline unless you intentionally want a different page size.
 - Reuse the CI superuser from `backend/.env.test` for login measurements unless you explicitly need another account.
 
 ## Recording Results
 
-`just perf-baseline` writes a raw `k6` summary export to `reports/performance/latest-k6-summary.json`.
-
-After a meaningful run, save a short dated markdown summary in `reports/performance/` so the numbers are easy to review in PRs.
-
-The current thresholds are provisional and were first calibrated from a dockerized baseline captured on `2026-03-30`. Recalibrate them after the first canonical CI-stack baseline capture.
-
-## Make CI The Baseline
-
-Use this flow to replace the historical docker-dev baseline with a canonical CI-stack baseline.
-
-For local work, use the Docker CI stack only to validate the mechanics:
-
-1. Run the baseline:
-   `just docker-ci-perf-baseline`
-
-Then use GitHub Actions as the calibration source of truth:
-
-1. Run the `Performance Baseline` workflow with `workflow_dispatch`.
-1. Download the `backend-perf-baseline-artifacts` artifact from that run.
-1. Replace `reports/performance/latest-k6-summary.json` locally with the artifact copy from GitHub.
-1. If those GitHub CI numbers should become the new regression baseline, use the maintainer-only perf helpers in `backend/justfile` to write a dated report and refresh thresholds.
-1. Rerun the workflow or a local Docker CI smoke run to confirm the refreshed thresholds behave as expected.
-1. Commit the new dated CI report and the updated thresholds in `perf/k6-baseline.js`.
-
-Treat that new CI report as the canonical baseline and keep older docker-dev reports only as historical context.
-
-## Notes On What We Measure
-
-- `/products/tree` is intentionally part of the baseline because it is a supported public hierarchical read, not just an internal implementation detail.
-- Tree performance should reflect the explicit bounded tree loader, not ORM lazy-loading side effects.
-- Do not make the perf workflow depend on embedded image data in `/products`; the baseline must stay useful even when no seeded image is present.
+`just perf-baseline` writes a raw `k6` summary export to `reports/performance/latest-k6-summary.json` (gitignored — local only).
 
-## Maintainer Note
+To recalibrate thresholds, run the `Performance Baseline` workflow with `workflow_dispatch`, download the `backend-perf-baseline-artifacts` artifact, then use the maintainer-only perf helpers in `backend/justfile` to refresh thresholds in `perf/k6-baseline.js`. Commit the updated thresholds. Include key numbers in the PR description rather than committing dated report files.
 
-Report writing and threshold refresh are maintenance operations, not routine commands. They stay available as hidden backend `just` recipes so the public task surface can stay small and stable.
+Threshold refresh is a maintenance operation, not a routine command. The helper recipes are hidden in `backend/justfile` to keep the public task surface small.

-## Notes
-
-- This capture predates the switch to using the Docker CI stack as the canonical perf target.
-- The initial placeholder thresholds were too aggressive for this environment and failed on the first capture.
-- Thresholds were recalibrated to modest headroom above this baseline so the suite catches obvious regressions without failing by default on a known-good Docker environment.
-- Product tree and image IDs came from existing seeded/sample dockerized data.
-- Future dated reports should use `just docker-ci-perf-baseline` from the repo root or `just perf-ci` from `backend/`.

+Using Creative Commons Public Licenses
+
+Creative Commons public licenses provide a standard set of terms and
+conditions that creators and other rights holders may use to share
+original works of authorship and other material subject to copyright
+and certain other rights specified in the public license below. The
+following considerations are for informational purposes only, are not
+exhaustive, and do not form part of our licenses.
+
+     Considerations for licensors: Our public licenses are
+     intended for use by those authorized to give the public
+     permission to use material in ways otherwise restricted by
+     copyright and certain other rights. Our licenses are
+     irrevocable. Licensors should read and understand the terms
+     and conditions of the license they choose before applying it.
+     Licensors should also secure all rights necessary before
+     applying our licenses so that the public can reuse the
+     material as expected. Licensors should clearly mark any
+     material not subject to the license. This includes other CC-
+     licensed material, or material used under an exception or

+
+     Considerations for the public: By using one of our public
+     licenses, a licensor grants the public permission to use the
+     licensed material under specified terms and conditions. If
+     the licensor's permission is not necessary for any reason--for
+     example, because of any applicable exception or limitation to
+     copyright--then that use is not regulated by the license. Our
+     licenses grant only permissions under copyright and certain
+     other rights that a licensor has authority to grant. Use of
+     the licensed material may still be restricted for other
+     reasons, including because others have copyright or other
+     rights in the material. A licensor may make special requests,
+     such as asking that all changes be marked or described.
+     Although not required by our licenses, you are encouraged to
+     respect those requests where reasonable. More considerations

+
+By exercising the Licensed Rights (defined below), You accept and agree

+Attribution 4.0 International Public License ("Public License"). To the
+extent this Public License may be interpreted as a contract, You are
+granted the Licensed Rights in consideration of Your acceptance of
+these terms and conditions, and the Licensor grants You such rights in
+consideration of benefits the Licensor receives from making the
+Licensed Material available under these terms and conditions.
+
+
+Section 1 -- Definitions.
+
+  a. Adapted Material means material subject to Copyright and Similar
+     Rights that is derived from or based upon the Licensed Material
+     and in which the Licensed Material is translated, altered,
+     arranged, transformed, or otherwise modified in a manner requiring
+     permission under the Copyright and Similar Rights held by the
+     Licensor. For purposes of this Public License, where the Licensed
+     Material is a musical work, performance, or sound recording,
+     Adapted Material is always produced where the Licensed Material is
+     synched in timed relation with a moving image.
+
+  b. Adapter's License means the license You apply to Your Copyright
+     and Similar Rights in Your contributions to Adapted Material in
+     accordance with the terms and conditions of this Public License.
+
+  c. Copyright and Similar Rights means copyright and/or similar rights
+     closely related to copyright including, without limitation,
+     performance, broadcast, sound recording, and Sui Generis Database
+     Rights, without regard to how the rights are labeled or
+     categorized. For purposes of this Public License, the rights
+     specified in Section 2(b)(1)-(2) are not Copyright and Similar
+     Rights.
+
+  d. Effective Technological Measures means those measures that, in the
+     absence of proper authority, may not be circumvented under laws
+     fulfilling obligations under Article 11 of the WIPO Copyright
+     Treaty adopted on December 20, 1996, and/or similar international
+     agreements.
+
+  e. Exceptions and Limitations means fair use, fair dealing, and/or
+     any other exception or limitation to Copyright and Similar Rights
+     that applies to Your use of the Licensed Material.
+
+  f. Licensed Material means the artistic or literary work, database,
+     or other material to which the Licensor applied this Public
+     License.
+
+  g. Licensed Rights means the rights granted to You subject to the
+     terms and conditions of this Public License, which are limited to
+     all Copyright and Similar Rights that apply to Your use of the
+     Licensed Material and that the Licensor has authority to license.
+
+  h. Licensor means the individual(s) or entity(ies) granting rights
+     under this Public License.
+
+  i. Share means to provide material to the public by any means or
+     process that requires permission under the Licensed Rights, such
+     as reproduction, public display, public performance, distribution,
+     dissemination, communication, or importation, and to make material
+     available to the public including in ways that members of the
+     public may access the material from a place and at a time
+     individually chosen by them.
+
+  j. Sui Generis Database Rights means rights other than copyright
+     resulting from Directive 96/9/EC of the European Parliament and of
+     the Council of 11 March 1996 on the legal protection of databases,
+     as amended and/or succeeded, as well as other essentially
+     equivalent rights anywhere in the world.
+
+  k. You means the individual or entity exercising the Licensed Rights
+     under this Public License. Your has a corresponding meaning.
+
+
+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part; and
+
+            b. produce, reproduce, and Share Adapted Material.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material (including in modified
+          form), You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+
+       3. If requested by the Licensor, You must remove any of the
+          information required by Section 3(a)(1)(A) to the extent
+          reasonably practicable.
+
+       4. If You Share Adapted Material You produce, the Adapter's
+          License You apply must not prevent recipients of the Adapted
+          Material from complying with this Public License.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database;
+
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material; and
+
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
+     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is
+     deemed unenforceable, it shall be automatically reformed to the
+     minimum extent necessary to make it enforceable. If the provision
+     cannot be reformed, it shall be severed from this Public License
+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.

-# RELab Backups
+# Relab Backups
 
-These scripts back up RELab data locally and can optionally sync it to remote storage.
+Relab uses one restic-based backup workflow for production and staging.
 
-Two kinds of data are covered:
+The backup container creates:
 
-- PostgreSQL backups
-- uploaded files and images
+- a logical PostgreSQL dump with `pg_dump` using `DATABASE_BACKUP_USER`
+- a restic snapshot of that dump tagged `postgres`
+- a restic snapshot of uploaded files tagged `user-uploads`
 
-## Important Note
+The restic repository is encrypted with `RESTIC_PASSWORD` / `RESTIC_PASSWORD_FILE`.
 
-By default, these scripts target services reachable from the host. If your stack runs in Docker, make sure the scripts point at the right database host and upload storage path. Do not assume the defaults match your deployment.
+## Runtime
 
-## Local Backups
-
-Set the root backup directory in the root `.env` file:
-
-```env
-BACKUP_DIR=/path/to/local/backups
-```
-
-The scripts create:
-
-- `$BACKUP_DIR/postgres_db`
-- `$BACKUP_DIR/user_upload_backups`
-
-### Manual Use
-
-Run from `backend/scripts/backup/`:
+The deploy overlay exposes the `relab-backup` service behind the `backups` profile:
 
 ```bash
-./backup_user_uploads.sh
-./backup_pg_database.sh
+just prod-up YES backups
+just staging-up YES backups
 ```
 
-### Automated Use
-
-From the repo root:
+Backups are stored under:
 
-```bash
-docker compose -f compose.yaml -f compose.deploy.yaml --profile backups up -d
+```text
+$BACKUP_HOST_DIR/restic
 ```
 
-This starts:
-
-- `uploads-backup` for user uploads
-- `postgres-backup` for PostgreSQL dumps
+For the Compose backup service, `BACKUP_HOST_DIR` is read from the host-local root
+`.env` file and defaults to `./backups`. Manual shell helpers such as
+`just restore-check` use already-exported environment variables instead
+of parsing `.env`; export `BACKUP_HOST_DIR` first when you need a non-default path.
+Non-secret prod/staging Compose interpolation lives in `deploy/env/*.compose.env`;
+do not put real secrets under `deploy/`.
 
-Schedules and retention settings live in [compose.deploy.yaml](../../../compose.deploy.yaml).
+## Required Secrets
 
-## Remote Sync
+The deploy Compose overlay declares the required backup secret files. Use
+`just deploy-secrets-template prod` or `just deploy-secrets-template staging` to
+create missing files, then replace the placeholder values. `just deploy-secrets-check` verifies that rendered Compose secrets point at the expected `secrets/<env>/` files.
 
-You can sync local backups to remote storage with either `rsync` or `rclone`. Both sync scripts include safety checks to reduce the chance of pushing an empty local directory over a valid remote backup set.
+## Restore Smoke Test
 
-### rsync
-
-Use this for SSH-accessible servers or local-network targets.
-
-Add to the root `.env`:
-
-```env
-BACKUP_RSYNC_REMOTE_HOST=user@hostname
-BACKUP_RSYNC_REMOTE_PATH=/path/to/remote/backup
-```
-
-Manual run:
+From the repo root, restore the latest database dump into a disposable Postgres container:
 
 ```bash
-./backend/scripts/backup/rsync_backup.sh
+just restore-check prod
 ```
 
-### rclone
+The smoke test restores the latest `postgres` snapshot, runs `pg_restore`, and verifies `SELECT 1` plus the `public.alembic_version` table.
 
-Use this for cloud or remote object storage.
+## Optional Offsite Copy
 
-Add to the root `.env`:
+Keep the local restic repository as the primary fast restore point. For offsite storage, copy restic snapshots to a second restic repository:
 
-```env
-BACKUP_RCLONE_REMOTE=myremote:/backup/relab
-BACKUP_RCLONE_MULTI_THREAD_STREAMS=16
+```bash
+RESTIC_OFFSITE_REPOSITORY=rclone:relab-webdav:relab/staging/restic just backup-offsite-copy staging
 ```
 
-Manual run:
+For WebDAV, configure an rclone remote in:
 
-```bash
-./backend/scripts/backup/rclone_backup.sh
+```text
+secrets/staging/rclone.conf
 ```
 
-## Cron Examples
+Production uses `secrets/prod/rclone.conf` and a separate repository path, for example:
 
-```cron
-30 3 * * * /path/to/relab/backend/scripts/backup/rsync_backup.sh >> /var/log/relab/rsync_backup.log 2>&1
-30 3 * * * /path/to/relab/backend/scripts/backup/rclone_backup.sh >> /var/log/relab/rclone_backup.log 2>&1
+```env
+RESTIC_OFFSITE_REPOSITORY=rclone:relab-webdav:relab/prod/restic
 ```
+
+Do not mirror the raw repository directory with separate rsync/rclone scripts. The supported offsite path is `restic copy`, with rclone acting only as restic's transport for WebDAV and other remotes.

+                             rule that excluded it; NOT part of the published archive
+
+Two deliberate departures from the April 2026 pipeline, which emitted a PostgreSQL dump:
+tabular data plus an image tree (a ``.sql.zst`` forces a reuser to stand up Postgres
+before they can look at anything, which is a poor front door for a computer-vision
+dataset), and the reference tables are *frozen* into the release rather than dropped
+(records pointing at absent material/producttype rows lose their meaning).
+
+The tabular data is Parquet with explicitly declared column types. CSV cannot tell a null
+mass from an empty string, or an integer count from a float, and for LCA numbers that
+ambiguity is where a silent unit or precision error enters someone else's analysis. Types
+are declared rather than inferred: a column that happens to be all-null in one release and
+populated in the next would otherwise change type between versions, which is the very
+reproducibility failure the frozen reference tables exist to prevent.
+
+The verification pass at the end is not optional and fails the build rather than warning.
+
+Scope is decided by consent: a record is in scope when its owner accepted the contributor
+terms. ``--owner`` narrows within that set, never past it, and every exclusion is counted,
+logged and listed in ``review/excluded-records.csv``.
+
+Run with: python -m scripts.build_dataset_release --out <dir>
+Or, to see what a release would contain without writing one:
+    python -m scripts.build_dataset_release --inventory

+
+## Scope
+
+Release {meta.version} contains lab-authored records only: teardowns carried out in house at
+CML. Records contributed through the public platform by other accounts are out of scope and
+are not included.
+
+- Records: {stats.records}
+- Images: {stats.images}
+- Distinct contributors: {stats.owners}
+- Collection period: {stats.collection_period}
+- Schema version: {SCHEMA_VERSION}
+- Pseudonym salt fingerprint: `{meta.pseudonym_salt_fingerprint}`
+
+## Contents
+
+| Path | What it holds |
+| --- | --- |
+| `records.parquet` | One row per record (a product or one of its components). |
+| `record_materials.parquet` | Bill-of-materials rows linking records to `reference/materials.parquet`. |
+| `images/` | Photographs, named by the SHA-256 of their own bytes. |
+| `manifest.csv` | Image file to record id, with checksum and pixel dimensions. |
+| `reference/` | Frozen taxonomy, categories, materials, product types and units. |
+| `croissant.json` | MLCommons Croissant description of this release. |
+| `SHA256SUMS` | Checksums for every file above. |
+
+## Format
+
+The tables are Apache Parquet with explicitly declared column types, so a missing mass
+reads as null rather than as zero or an empty string, and integer counts stay integers.
+Read one with any Arrow-aware tool:
+
+```python
+import pyarrow.parquet as pq
+
+records = pq.read_table("records.parquet")
+```
+
+`manifest.csv` and `SHA256SUMS` are deliberately plain text: they are operational files for
+looking up a path or a checksum by hand, not dataset tables.
+
+The reference tables are frozen into the release rather than referenced remotely: a record
+that points at a material or product type which is no longer in the live database would
+otherwise lose its meaning.
+
+Owner identity is replaced by a stable pseudonym (`owner-<16 hex>`). The same person keeps
+the same pseudonym across releases and cannot be re-identified from the release alone. The
+salt fingerprint above identifies which salt generation produced them: two releases sharing
+a fingerprint have comparable pseudonyms, and one that differs does not. It is derived from
+the salt but does not reveal it.
+
+## Known biases
+
+- **Product class.** Power tools only. Nothing here generalises to other product categories.
+- **Geography.** Collected in the Netherlands, from Dutch second-hand and waste streams.
+- **Sample size.** Small n. Treat aggregate figures as indicative, not representative.
+- **Capture setup.** Photographs come from a small number of teardown benches and cameras,
+  so background and lighting are far more uniform than in the field.
+
+## Licence
+
+All records and images are licensed under {meta.licence_name} ({meta.licence_url}).
+The full text is in `LICENSE.txt`.
+
+### Trademarks are not licensed
+
+Teardown photographs of power tools show brand marks, logos and model numbers — that is
+unavoidable in the subject matter. The licence covers the images and the data. It grants no
+rights in the trademarks visible in them; CC BY 4.0 says so in section 2(b)(2). Research,
+analysis, model training and publication of results are unaffected. If you intend to use
+the images in a way that suggests endorsement by or affiliation with a brand, that is a
+trademark question and you need to consider it separately from this licence.
+
+### Personal data is not governed by the licence
+
+An open licence grants copyright and database rights. It says nothing about data
+protection. What makes this release publishable is the sanitisation and pseudonymisation
+step, not {meta.licence_name}.
+
+The release carries no account identifiers. Contributor identity appears only as a stable
+pseudonymous code, and contributors are credited collectively rather than individually.
+Re-identifying contributors, or combining this release with other sources in order to do so,
+falls outside both the licence and the GDPR basis on which the release was published.
+
+## Attribution

+## Citation

+"""Backfill ``width_px``/``height_px`` on Image rows that predate the columns.
+
+Dimensions are recorded at upload from the header the processor already parses,
+so only rows written before that landed are NULL. Until this runs, clients get
+no aspect ratio for those images and fall back to picking a derivative by width
+alone.
+
+Reading is cheap: Pillow's ``open`` parses the header without decoding pixels,
+so this is one header read per image rather than a full decode. Rows whose file
+is missing, unreadable, or remote (S3) are left NULL and logged, never failed on;
+they are re-selected on the next run, so a deployment with such rows sees the
+same warnings each time.
+
+Rows are measured in batches with a commit per batch, so an interrupted run
+keeps everything measured so far and the next run picks up where it stopped:
+the ``IS NULL`` predicate advances the cursor by itself.

+"""Deposit a built dataset release to Zenodo as a DRAFT.
+
+Publication is irreversible: a published Zenodo record cannot be withdrawn, only
+tombstoned, and its files can never be changed. So this script creates or versions a
+*draft* deposit and stops there. Publishing is a second, explicit invocation with
+``--publish``, and it prompts before it sends anything.
+
+The token is read the way the rest of the backend reads secrets: from
+``secrets/<ENVIRONMENT>/zenodo_token`` (or ``/run/secrets`` in a container), with
+``ZENODO_TOKEN`` as an override for a one-off run. It needs the
+``deposit:write`` scope, plus ``deposit:actions`` to publish.
+
+Typical run, after ``just release-build``::
+
+    uv run python -m scripts.zenodo_deposit --dir dist/dataset-v1.0
+    # to resume an interrupted upload into the same draft, add --deposition 1234567
+    # inspect the draft in the Zenodo web UI, then:

+# Backend Tests
+
+This directory is split into a few tiers so we can keep fast unit tests separate from persistence, runtime, and end-to-end coverage.
+
+## Tiers
+
+### `tests/unit/`
+
+Use this tier for isolated fast tests only.
+
+- No Docker or database startup
+- No real app lifespan unless the behavior is fully mocked and still isolated
+- Prefer local stubs, parametrization, and function-based tests
+- Prefer small behavior-focused files over domain-sized catch-all modules
+- Patch the owning module seam directly
+  - example: patch `product_commands` or `product_tree_queries`, not a broad legacy facade
+- Keep helper modules private and local to one test area when possible; avoid recreating package-level test registries
+
+### `tests/integration/api/`
+
+Use this tier for request/response behavior against the ASGI app with real routing, dependency overrides, and database-backed state when needed.
+
+- Preferred fixtures: `api_client`, `api_client_user`, `api_client_superuser`, `db_session`
+- Keep each test focused on one endpoint behavior
+- Avoid multi-step CRUD stories here; move those to `tests/integration/flows/`
+- Prefer small behavior-focused files such as `*_public_*`, `*_membership_*`, `*_callbacks_*` over one large endpoint catch-all module
+- Keep fixture/plugin modules separate from pure helper modules so pytest plugin loading stays explicit and warning-free
+
+### `tests/integration/db/`
+
+Use this tier for database-backed tests that exercise ORM models, CRUD, queries, and migrations without going through HTTP routing.
+
+- Allowed fixtures: `db_session`, seed/data fixtures, factories
+- Not required by default: `api_client`, app lifespan, routing stack
+- Goal: verify persistence and query behavior with a real database
+
+### `tests/integration/core/`
+
+Use this tier for runtime-adjacent integration coverage that does not belong to HTTP request tests or direct persistence tests.
+
+- Good fits include lifespan, logging, cache wiring, file cleanup, database operations, and migration behavior that touches the app runtime
+- Keep these tests focused on one subsystem at a time
+- Prefer explicit fixtures over broad startup behavior unless the runtime path itself is under test
+
+### `tests/integration/flows/`
+
+Flow tests cover a small number of multi-step scenarios that cross feature boundaries.
+
+Use this tier only when a single test needs to prove an end-to-end journey such as authenticate -> mutate -> fetch, or camera setup -> record -> persist.
+
+Keep these tests sparse and slower than the unit and API tiers on purpose.

-# API Integration Tests
-
-Use this tier for request/response behavior against the ASGI app with real routing, dependency overrides, and database-backed state when needed.
-
-- Preferred fixtures: `api_client`, `api_client_user`, `api_client_superuser`, `db_session`
-- Keep each test focused on one endpoint behavior
-- Avoid multi-step CRUD stories here; move those to `tests/integration/flows/`
-- Move multi-step scenarios to `tests/integration/flows/`
-- Prefer small behavior-focused files such as `*_public_*`, `*_membership_*`, `*_callbacks_*` over one large endpoint catch-all module
-- Keep fixture/plugin modules separate from pure helper modules so pytest plugin loading stays explicit and warning-free

-# Unit Tests
-
-Use this tier for isolated fast tests only.
-
-- No Docker or database startup
-- No real app lifespan unless the behavior is fully mocked and still isolated
-- Prefer local stubs, parametrization, and function-based tests
-- Prefer small behavior-focused files over domain-sized catch-all modules
-- Patch the owning module seam directly
-  - example: patch `product_commands` or `product_tree_queries`, not a broad legacy facade
-- Keep helper modules private and local to one test area when possible; avoid recreating package-level test registries

+# Production cutover: `main` → the MVP release
+
+One-time runbook for upgrading the production host from the `main` revision to
+the current release. Written 2026-08-03.
+
+Supersedes `secrets/prod/PROD_MIGRATION_PLAYBOOK.md`. That playbook described
+the role-hardening, encryption, and restic work as if it were being applied in
+May — but none of it exists on `main`, so **prod never received it**. Those
+steps are folded into this document instead (5, 8a, and 10).
+
+This file is committed deliberately: it contains no secrets, and the previous
+playbook lived under `secrets/`, which is gitignored and therefore never reached
+the deploy host.
+
+Prod's Alembic revision is `6f2b9e4a1c3d`.
+
+> **Every revision literal and migration count below is a historical observation,
+> not a current fact.** Written 2026-08-03 (head `f1a2b3c4d5e6`, 20 migrations);
+> as of 2026-08-18 the head was `c4f7b1e93a20` and prod had 27 to apply. Re-derive
+> before the window:
+>
+> ```bash
+> cd backend
+> uv run alembic heads                            # the revision step 9 must find
+> uv run alembic history -r 6f2b9e4a1c3d:head     # prod's revision + each pending one
+> ```
+>
+> That range includes prod's own revision, so one fewer migration runs than lines
+> printed. Only the *count* moves: the path is still forward-only and still one
+> transaction.
+
+Prod's *code* is not literally at `main` — it sits on a pre-rewrite lineage of
+the working branch from April (step 0). For deployment purposes the two are
+equivalent, and that was checked rather than assumed: prod's tip and `main`
+declare the **same** Compose services (`api`, `app-site`, `docs-site`,
+`web-site`, `migrator`, `postgres`, `redis`, `cloudflared`, `postgres-backup`,
+`uploads-backup`), the **same** volumes (`database_data`, `user_uploads`,
+`cache_data`), the same `relab_prod` project name, the same `backend/.env.prod`
+config mechanism, and the same migration lineage. Everything below that is phrased
+as "on `main`" therefore applies to the host as it actually is.
+
+## What makes this cutover different
+
+This is not a routine deploy. The deployment layout itself changed:
+
+- Backend configuration moves out of a hand-maintained `backend/.env.prod` into
+  16 files under `secrets/prod/`. **`backend/.env.prod` is no longer read at
+  all**, and `main` had no secret-file mechanism whatsoever, so these files
+  likely do not exist on prod yet and must be created from the values currently
+  in `backend/.env.prod`.
+- Three least-privilege database roles are expected to exist. `main` has no
+  role-hardening script at all, and the scripts that create them only run on an
+  empty Postgres volume — **so they must be created by hand on prod.**
+- OAuth tokens and YouTube broadcast keys are stored **in plaintext** on `main`
+  (it has no `data_encryption_key`). They need a one-time encryption pass.
+- Five services were renamed, so the old stack must be stopped from the *old*
+  checkout or it leaves orphaned containers running.
+- Backups become an encrypted restic repository. `main` has no restic tooling,
+  so this is first-time setup, not a re-enable.
+- ClamAV is new, needs 3–4 GiB, and is now behind the `scanning` profile.
+
+The staging host has its own state and outstanding work; see
+[CUTOVER-STAGING.md](CUTOVER-STAGING.md). Staging shares `compose.deploy.yaml` with prod, so
+anything unfinished there is also unrehearsed here.
+
+Read sections 0 and 1 fully before touching anything. Steps 2–6 are preparation
+and can be done ahead of the window; the outage starts at step 7.
+
+______________________________________________________________________
+
+## 0. Establish what prod actually is — do this first
+
+This section was run on 2026-08-03 and its findings are recorded below. Re-run
+it on the day of the cutover rather than trusting them — the host can move.
+
+On the deploy host:
+
+```bash
+cd /path/to/relab
+git status                        # dirty tree? uncommitted hotfixes?
+git log --oneline -5              # what revision is actually deployed
+git fetch origin
+git log --oneline origin/main..HEAD   # see the caveat below before reading this
+
+# Actual Alembic revision (the real input to the migration plan)
+docker compose -p relab_prod exec -T postgres \
+  psql -U "$PGSUPERUSER" -d relab_db -c 'SELECT version_num FROM alembic_version;'
+
+# Which config mechanism is live
+ls -la backend/.env.prod 2>/dev/null   && echo 'env-file config (main-era)'
+ls -la secrets/prod/ 2>/dev/null        && echo 'secret files already present'
+
+# Cluster superuser and whether the least-privilege roles exist
+docker compose -p relab_prod exec -T postgres psql -U "$PGSUPERUSER" -d relab_db -c '\du'
+```
+
+### What this found (checked 2026-08-03)
+
+Prod is **not** at `main`. It sits on a pre-rewrite lineage of the working
+branch, tip `2abd707e` dated **2026-04-24** — roughly three months of drift, and
+older than the `frontend-app/` → `app/` rename.
+
+The working branch history was rewritten at some point, so prod's commits will
+never appear in `origin`: the same release commit exists twice under different
+hashes (`5e13df20` on prod vs `39c58600` on `main`). That makes
+`origin/main..HEAD` misleading — it lists ~70 commits that are mostly a rewrite
+artifact, not genuine local work. Comparing by content instead:
+
+- The six commits after prod last merged `main` are all 2026-04-24, and their
+  content is already in the release. The one functional change among them, the
+  `numColumns` paging fix (`83b2dda0`), survives verbatim in
+  `app/src/features/products/screenData.ts`. The rest (CI workflow
+  consolidation, biome schema paths, an Expo Dockerfile env fix, linting) are
+  superseded by later work.
+- **Nothing needs porting off the prod host.** Verify this again before the
+  window rather than trusting this paragraph, but that was the finding.
+
+The old lineage is preserved locally as the branch `backup/pre-rewrite-working`,
+which is **not on origin**. Push it before the cutover, so the only copies are
+not one laptop and one production host:
+
+```bash
+git push origin backup/pre-rewrite-working
+```
+
+Because the histories diverged, do not try to `git pull` or merge on prod — it
+will conflict across the directory rename. Tag the current state, then check the
+release out cleanly:
+
+```bash
+git tag prod-pre-mvp-$(date +%Y%m%d) && git push origin --tags   # if origin is reachable
+git checkout <release-branch> && git pull --ff-only
+```
+
+### The reassuring part: the schema plan is unaffected
+
+Prod's Alembic revision is `6f2b9e4a1c3d`, and the migration surface at prod's
+April tip is **identical to `main`** — 20 files, no extras. So despite the code
+drift, the database is exactly where this runbook assumes, and the forward-only
+path applies unchanged — it is simply longer now (27 migrations to
+`c4f7b1e93a20`, re-derive on the day). That path was verified by replaying it
+against a seeded scratch database at `6f2b9e4a1c3d`.
+
+The four answers that drive the rest of this document:
+
+| Question                                 | Answer as of 2026-08-03                                                                                      |
+| ---------------------------------------- | ------------------------------------------------------------------------------------------------------------ |
+| Alembic revision                         | `6f2b9e4a1c3d` — matches `main`, so the forward-only plan applies unchanged (27 migrations as of 2026-08-18) |
+| `backend/.env.prod` present?             | Yes — it is the **source** for the secret files created in step 4                                            |
+| `secrets/prod/` present?                 | No — step 4 creates all 16 from scratch                                                                      |
+| Superuser name, `relab_*` roles present? | Custom name from `backend/.env.prod`; no `relab_*` roles, so step 5 is required                              |
+
+Re-confirm these on the day rather than trusting the table: it records one
+observation, and anything could change in between.
+
+`$PGSUPERUSER` throughout this document is whatever that `\du` reports — on
+`main` it came from `backend/.env.prod`, so it is **not** necessarily `postgres`.
+
+## 0a. Rehearse, and confirm the release gates — before the window
+
+Three checks that are easy to skip because none of them touch the prod host, and
+all three are cheaper to fix now than mid-outage.
+
+### Rehearse the whole thing on staging
+
+The running staging stack was deployed from an older, structurally different
+compose file, so it has **never exercised this release's deploy path** — not the
+secret-file layout, not the least-privilege roles, not restic. Staging shares
+`compose.deploy.yaml` with prod, driven by the host's root `.env`, so a full
+`staging-*` pass is a genuine rehearsal of steps 4 through 10:
+
+```bash
+just staging-build
+just staging-up YES scanning
+just staging-migrate YES
+just backup staging          # initializes the repo; the smoke test needs a snapshot
+just restore-check staging
+```
+
+Every step below that surprises you on staging would have surprised you on prod.
+Do this even if staging's data is uninteresting — what is being rehearsed is the
+*procedure*, not the data.
+
+### Confirm the CI gate actually blocks merges
+
+`just ci` runs in `.github/workflows/validate.yml`, whose terminal job is
+`validate-result`. Branch protection is **not** stored in the repository, so
+whether that job is a required check cannot be verified from the code:
+
+```bash
+gh api repos/:owner/:repo/branches/main/protection \
+  --jq '.required_status_checks.contexts'
+```
+
+`validate-result` must appear. If the call 404s, there is no protection at all
+and every gate in this release is advisory. Record the answer as launch
+evidence.
+
+### Read what release-please proposes
+
+`CHANGELOG.md` is frozen at `v0.2.0` (2026-04) while `release-please` owns
+versioning from conventional commits on push to `main`. With
+`bump-minor-pre-major: true` and several months of commits, the proposed bump is
+worth reading rather than trusting after the fact — it also rewrites version
+strings into nine `extra-files`, including `CITATION.cff`, `app/app.json`, and
+every `package.json`:
+
+```bash
+gh pr list --label 'autorelease: pending' --state open
+```
+
+Confirm the version and changelog match this release's actual scope **before**
+merging that PR.
+
+## 0b. Abort rule
+
+Do not remove the old volume, the old backup directory, or `backend/.env.prod`
+until all of the following hold:
+
+- the post-upgrade verification in step 9 passes,
+- an upload, an OAuth login, and a product page have been exercised by hand,
+- `just restore-check prod` succeeds.
+
+The migration runs as a **single transaction** (`backend/alembic/env.py` never
+sets `transaction_per_migration`), so any failure during step 8 rolls the schema
+back to `6f2b9e4a1c3d` untouched — no partial state, no `alembic stamp` repair.
+One statement escapes that transaction by necessity (a `CONCURRENTLY` index
+drop); see "The seven migrations added after this runbook was written" in §3 for
+what that does and does not change. It is idempotent, so a retry is still clean.
+The irreversible risks are the *data* losses flagged in step 3, which the
+pre-upgrade dump is the only recovery path for.
+
+______________________________________________________________________
+
+## 1. Preparation on the deploy host (no downtime)
+
+```bash
+cd /path/to/relab
+git fetch origin
+git status                 # confirm a clean tree before switching
+```
+
+Record the current state while the old stack is still running:
+
+```bash
+docker ps -a --format '{{.Names}}\t{{.Image}}' | tee ~/relab-cutover/containers-before.txt
+docker volume ls | grep relab | tee ~/relab-cutover/volumes-before.txt
+```
+
+Volumes are **not** renamed in this release — `relab_prod_database_data`,
+`relab_prod_user_uploads`, and `relab_prod_cache_data` carry over untouched, and
+the project name is still `relab_prod`. No volume migration is needed.
+
+### 1a. Decide whether to run ClamAV
+
+`clamav` sits behind the `scanning` Compose profile. It needs 3–4 GiB of RAM,
+and its first start downloads virus signatures into a fresh `clamav_db` volume,
+which can take several minutes during which the API stays unhealthy.
+
+```bash
+free -g
+```
+
+**With enough RAM** — run it, and pass the profile on every up/down:
+
+```bash
+just prod-up YES scanning
+```
+
+`up` starts no backup service — a systemd timer owns that (§10), so `scanning` is
+normally the only profile you pass here.
+
+**Without** — omit the profile *and* disable scanning in the root `.env`, or
+uploads fail closed:
+
+```env
+MALWARE_SCAN_ENABLED=false
+```
+
+`prod-up` enforces this pairing: it refuses to start when `MALWARE_SCAN_ENABLED`
+is anything but `false` while the `scanning` profile is off. Whichever way you
+decide here, the rest of this runbook's `prod-up` commands assume it — keep the
+`scanning` profile on every one of them, or drop it from every one.
+
+Running without scanning means uploaded files are not checked for malware on a
+platform that accepts uploads from external contributors. Treat it as an
+explicit, temporary accepted risk, not a default.
+
+______________________________________________________________________
+
+## 2. Take the backup that everything else depends on
+
+```bash
+mkdir -p ~/relab-cutover
+docker compose -p relab_prod exec -T postgres \
+  pg_dump -U "$PGSUPERUSER" -d relab_db --format=custom \
+  > ~/relab-cutover/prod-pre-mvp.dump
+
+docker run --rm \
+  -v relab_prod_user_uploads:/uploads:ro \
+  -v ~/relab-cutover:/out \
+  alpine:3.22 tar -C /uploads -czf /out/user_uploads-pre-mvp.tar.gz .
+
+ls -lh ~/relab-cutover        # both must be non-empty
+```
+
+`$PGSUPERUSER` is whatever your cluster was initialized with — see step 5, this
+is very likely **not** `postgres`.
+
+Also preserve the old backup directory: the release replaces the plain-copy
+backup services with an encrypted **restic** repository, and the old dumps are
+not readable by the new tooling.
+
+```bash
+cp -a "${BACKUP_DIR:-./backups}" ~/relab-cutover/old-backups
+```
+
+______________________________________________________________________
+
+## 3. Pre-flight data checks (read-only, run against live prod)
+
+Run these *before* the window. Each one exists because a migration either aborts
+or destroys data. Record every number — step 9 compares against them.
+
+```bash
+docker compose -p relab_prod exec -T postgres psql -U "$PGSUPERUSER" -d relab_db
+```
+
+```sql

+```
+
+### The quota lockout (query E) — expect this to bite
+
+The release adds a per-user upload ledger. `upload_file_count` is backfilled
+**accurately** from real rows, and enforcement is
+`User.upload_file_count < file_limit`. Since 2026-08-18 the limit is not one
+number: it is **tiered by the account's role**, and every account is created and
+backfilled as `contributor`.
+
+| Role          | Files  | Storage  | Root `.env` overrides                                               |
+| ------------- | ------ | -------- | ------------------------------------------------------------------- |
+| `contributor` | 1000   | 1024 MB  | `MAX_UPLOAD_FILES_PER_USER`, `MAX_UPLOAD_BYTES_PER_USER_MB`         |
+| `lab`         | 20 000 | 20480 MB | `MAX_UPLOAD_FILES_PER_LAB_USER`, `MAX_UPLOAD_BYTES_PER_LAB_USER_MB` |
+
+`media_count` in query E counts **files and images**, not products, across base
+products and components alike.
+
+With ~3,610 images concentrated in the lab account, that account lands far above
+the contributor limit of 1000 and is **blocked from all further uploads** the
+moment the app restarts, returning `413 Upload quota exceeded`. Nothing is
+deleted and no existing file is affected — only new reservations fail.
+
+**The fix is step 8b: promote that account to `lab`, not raise the contributor
+tier.** Raising the contributor ceiling to cover one lab account hands the same
+ceiling to every external contributor, which is the opposite of what the role
+model exists to do. Raise the *lab* tier instead if 20 000 is genuinely too low:
+
+```env
+MAX_UPLOAD_FILES_PER_LAB_USER=50000
+```
+
+A lab value below its contributor counterpart is refused at settings validation,
+so the stack will not start on an inverted pair rather than silently downgrading
+lab accounts.
+
+Related: `upload_size_bytes` is added with a default of `0`, so every
+pre-existing file counts as zero bytes until backfilled. Step 8 now runs
+`just backfill-upload-sizes` right after the migration to populate it from the
+real files on disk/storage — until that runs, `upload_total_bytes` reads 0 for
+every user and byte-based quota is meaningless. Leave
+`MAX_UPLOAD_BYTES_PER_USER_MB` high enough that it cannot bite in the gap
+between migrate and backfill.
+
+### The seven migrations added after this runbook was written
+
+`f1a2b3c4d5e6` (the original target) to `c4f7b1e93a20` (the head) adds seven
+revisions that §3's queries above were never written against. They were audited
+on 2026-08-18; the summary is reassuring, with three caveats worth knowing
+before the window rather than during it.
+
+| Revision       | What it does                         | Aborts on data? | Drops data? |
+| -------------- | ------------------------------------ | --------------- | ----------- |
+| `bfd99abac57f` | Adds two nullable terms columns      | No              | No          |
+| `c3e7b1a90d24` | Drops a redundant index CONCURRENTLY | No              | No          |
+| `d4b8e1c60a72` | `pg_trgm` + search/thumbnail indexes | No              | No          |
+| `34345aa9c369` | Adds `image.width_px`/`height_px`    | No              | No          |
+| `7c1f3b6a52d8` | Validates the dimensions CHECK       | No (see below)  | No          |
+| `b7e2d9a4c1f0` | Trigram index on `producttype`       | No              | No          |
+| `c4f7b1e93a20` | Adds `user.role` + its CHECK         | No              | No          |
+
+**None of the seven aborts on bad data and none drops data**, so §3 needs no new
+data query for them — only query H, above, for lock contention.
+
+`7c1f3b6a52d8` looks like an exception because `VALIDATE CONSTRAINT` does abort
+on a violating row. It cannot here: `width_px`/`height_px` are added nullable two
+revisions earlier and nothing in the chain backfills them, so every row is NULL
+and the constraint (`IS NULL OR > 0`) is trivially satisfied. Its 15-minute
+statement ceiling is for the table scan, which is nothing at prod's row count.
+
+`d4b8e1c60a72` runs `CREATE EXTENSION IF NOT EXISTS pg_trgm` as `relab_migrator`,
+which is `NOSUPERUSER`. That works, and was checked rather than assumed: `pg_trgm`
+is a **trusted** extension in the pinned `postgres:18` image, and step 5's role
+script grants `CREATE ON DATABASE` to the migrator — a trusted extension needs
+only that, not the SUPERUSER attribute (which role membership never confers).
+
+**Correction to §0b's abort rule.** `c3e7b1a90d24` drops its index inside an
+`autocommit_block()`, because `CONCURRENTLY` cannot run in a transaction. So the
+run is no longer strictly all-or-nothing: if a later migration fails, that one
+index stays dropped while `alembic_version` rolls back. The practical impact is
+nil — the drop is `if_exists=True`, so a retry is clean, and the index was
+redundant — but "the migration runs as a single transaction" is now approximate,
+and a post-failure schema may differ from the pre-run one by exactly that index.
+
+**A consequence that outlives the cutover: nobody has accepted the contributor
+terms — but the app now asks.** `bfd99abac57f` adds
+`terms_accepted_version`/`terms_accepted_at` deliberately without a backfill —
+stamping a value would fabricate evidence of a licence grant nobody made. Until
+2026-08-18 acceptance was recorded only at registration, with no way for an
+existing account to accept later, which left every pre-existing contributor
+permanently unable to consent and their records permanently unpublishable
+(`scripts/build_dataset_release.py::check_owner_selection` refuses them).
+
+That gap is now closed: the app prompts on the next login after this deploy, and
+`POST /v1/users/me/accept-terms` records the grant server-side. Declining is free
+and changes nothing, so **expect the backlog to clear gradually rather than at
+once** — a contributor who has not logged in since the cutover has still granted
+nothing. Before building a release, check who is covered:
+
+```sql
+SELECT count(*) FILTER (WHERE terms_accepted_version IS NOT NULL) AS accepted,
+       count(*) FILTER (WHERE terms_accepted_version IS NULL)     AS not_yet
+FROM "user";
+```
+
+Nothing here blocks the cutover. It blocks a dataset release naming any account
+still in the `not_yet` column.
+
+______________________________________________________________________
+
+## 4. Migrate secrets to the new layout
+
+The release reads secrets as **files** under `secrets/prod/`, via
+pydantic-settings `secrets_dir`. `backend/.env.prod` is no longer loaded.
+
+Which path applies depends on what step 0 found.
+
+**If `secrets/prod/` does not exist on the host** (expected — `main` had no
+secret-file mechanism at all), you are creating all 16 from scratch, and the
+values must come out of the live `backend/.env.prod`. Generate the scaffolding
+first, then overwrite the carried-over ones by hand:
+
+```bash
+just deploy-secrets-template prod    # creates all 16 at 0644 with fresh values
+```
+
+The directory is `0700` and the files are `0644`: the containers run as uid 1001
+and must be able to read the mounted files, while the directory keeps them
+private from other users on the host.
+
+Then, for each row below, replace the generated file's contents with the value
+already in `backend/.env.prod`. **Carrying these across matters** — a fresh
+value is not equivalent:
+
+| `backend/.env.prod` variable    | `secrets/prod/` file            | Why it must be carried over                                                                                |
+| ------------------------------- | ------------------------------- | ---------------------------------------------------------------------------------------------------------- |
+| `FASTAPI_USERS_SECRET`          | `auth_token_secret`             | Signs password-reset and verification links; a new value invalidates every link already in someone's inbox |
+| `SUPERUSER_PASSWORD`            | `bootstrap_superuser_password`  | Your documented emergency admin password                                                                   |
+| `POSTGRES_PASSWORD`             | `postgres_password`             | Must match the existing cluster or nothing connects                                                        |
+| `REDIS_PASSWORD`                | `redis_password`                | Must match the running cache                                                                               |
+| `OAUTH_STATE_SECRET`            | `oauth_state_secret`            | Invalidates in-flight OAuth logins if changed                                                              |
+| `CACHE_SIGNING_SECRET`          | `cache_signing_secret`          | Invalidates signed cache entries if changed                                                                |
+| `GOOGLE_OAUTH_CLIENT_SECRET`    | `google_oauth_client_secret`    | Real credential, cannot be invented                                                                        |
+| `GITHUB_OAUTH_CLIENT_SECRET`    | `github_oauth_client_secret`    | Real credential                                                                                            |
+| `MICROSOFT_GRAPH_CLIENT_SECRET` | `microsoft_graph_client_secret` | Real credential                                                                                            |
+| `EMAIL_PASSWORD`                | `smtp_password`                 | Real credential                                                                                            |
+
+Write them without leaving values in shell history:
+
+```bash
+install -m 644 /dev/null secrets/prod/auth_token_secret
+printf '%s\n' 'VALUE_FROM_ENV_PROD' > secrets/prod/auth_token_secret   # repeat per row
+```
+
+The three `database_*_password` files and `restic_password` are new — the
+generated random values are correct, and the database ones are consumed by the
+roles you create in step 5. `data_encryption_key` is also new; keep the
+generated value and **record it**, because step 6a encrypts existing data with
+it and the data is unreadable without it.
+
+**If `secrets/prod/` already exists** with the old names, the delta is just two
+renames — copy, do not regenerate:
+
+```bash
+cp secrets/prod/fastapi_users_secret secrets/prod/auth_token_secret
+cp secrets/prod/superuser_password   secrets/prod/bootstrap_superuser_password
+```
+
+Fill any remaining gaps and verify:
+
+```bash
+chmod 700 secrets/prod              # one-time: the directory carries the privacy
+chmod 644 secrets/prod/*            # one-time: uid 1001 in the containers must read these
+just deploy-secrets-template prod   # creates only what is missing, 0644
+just env-inventory                  # the 16 expected names
+just deploy-secrets-check
+```
+
+`deploy-secrets-template` now generates real random values rather than
+`replace-me-*` placeholders, except for external identity credentials
+(`*_oauth_client_secret`, `microsoft_graph_client_secret`) which it cannot
+invent — those are created **empty** instead. Empty is valid for a provider
+you aren't using: an empty *optional* input passes `env-inventory`/env-policy,
+an empty *required* one still fails loudly, and the runtime accepts empty for
+unused providers. **Fill in by hand** whichever providers you actually use.
+`deploy-secrets-check` still rejects carried-over legacy placeholder values:
+the current `replace-me-*` marker and the May-era `placeholder-<env>-<name>`
+scaffolding (a dozen of the latter were found lurking on the staging host on
+2026-08-12 — old trees can carry them).
+
+Leave the two old files (`fastapi_users_secret`, `superuser_password`) in place
+until the cutover is verified, then delete them.
+
+______________________________________________________________________
+
+## 5. Create the database roles by hand — do not skip
+
+The release connects as three least-privilege roles (`relab_app`,
+`relab_migrator`, `relab_backup`) instead of the cluster superuser.
+`deploy/postgres/initdb/10-relab-roles.sh` creates them, but
+`/docker-entrypoint-initdb.d` scripts **only run when the data directory is
+empty**. Prod's volume is populated, so they will never run and the API will
+fail to connect.
+
+First establish what your cluster actually is — staging, for reference, has a
+single login role `cml_test_admin` and no `postgres` role at all:
+
+```bash
+docker compose -p relab_prod exec -T postgres \
+  psql -U "$PGSUPERUSER" -d relab_db -c "\du"
+```
+
+> **If the superuser is not named `postgres`:** `compose.deploy.yaml` defaults
+> `POSTGRES_USER` to `postgres`. Do not expect the healthcheck to catch the
+> mismatch — `pg_isready` treats a `FATAL: role does not exist` response as
+> "server accepting connections", so the container reports **healthy** while
+> the role script and every real client fail (observed on staging 2026-08-12).
+> Resolve it before the window — set `POSTGRES_SUPERUSER=<role>` in the host's
+> root `.env` (or create a `postgres` superuser role in the cluster). This is a
+> genuine mismatch that the stack will not surface on its own.
+
+Then run the role script against the live database. It is idempotent and
+already mounted inside the container, so run it directly rather than
+transcribing it — hand-copying is how the per-role timeouts at the bottom get
+missed:
+
+```bash
+docker compose -p relab_prod exec -T postgres bash /docker-entrypoint-initdb.d/10-relab-roles.sh
+```
+
+It reads the role names from the container environment and the passwords from
+the mounted `secrets/prod/database_*_password` files, so there is nothing to
+fill in. Replayed against a populated database it will:
+
+- create only the roles that do not exist yet, leaving any existing role's
+  password untouched;
+- grant on the tables and sequences that **already exist**, which
+  `ALTER DEFAULT PRIVILEGES` alone does not cover;
+- apply `statement_timeout`, `lock_timeout` and
+  `idle_in_transaction_session_timeout` to `relab_app`.
+
+No downtime is needed: `ALTER ROLE ... SET` applies to new sessions, so restart
+the API afterwards (or wait out the 30-minute connection recycle) for the
+timeouts to take effect on the pool.
+
+**Then grant the migrator ownership rights — the grants above are not enough.**
+On an adopted cluster every existing table (including `alembic_version`) is
+owned by `$PGSUPERUSER`, and Postgres requires *ownership*, not grants, for the
+DDL the migrations run. The role script cannot know this (on a fresh cluster
+the migrator owns everything it creates), so do it by hand:
+
+```bash
+docker compose -p relab_prod exec -T postgres \
+  psql -U "$PGSUPERUSER" -d relab_db -c "GRANT \"$PGSUPERUSER\" TO relab_migrator;"
+```
+
+Role *membership* confers ownership rights on the superuser's objects without
+conferring the SUPERUSER attribute (attributes are never inherited). Without
+this, step 8's migration fails immediately with
+`permission denied for table alembic_version` — found live in the staging
+rehearsal on 2026-08-12; the §0 scratch replay never caught it because a
+scratch database is created fresh, where the migrator owns what it makes.
+
+Verify all three roles exist and can log in before continuing.
+
+______________________________________________________________________
+
+## 6. Update the root `.env`
+
+Backend settings that used to live in `backend/.env.prod` are now split: secrets
+into `secrets/prod/`, non-secret public URLs into the committed
+`deploy/env/prod.compose.env` (do not edit it), and operator inputs into the
+root `.env`.
+
+**Required — the stack will not render without these:**
+
+```env
+CLOUDFLARE_TUNNEL_TOKEN=…   # renamed from TUNNEL_TOKEN, same value
+EMAIL_PROVIDER=smtp         # or microsoft_graph
+EMAIL_FROM=…
+EMAIL_REPLY_TO=…
+BOOTSTRAP_SUPERUSER_EMAIL=…
+GOOGLE_OAUTH_CLIENT_ID=…    # carry from backend/.env.prod — the app refuses to
+GITHUB_OAUTH_CLIENT_ID=…    # boot in prod/staging when either is empty
+```
+
+The OAuth client *IDs* are non-secret and live here; the client *secrets* went
+to `secrets/prod/` in step 4. Found live in the staging rehearsal: with the IDs
+absent, `prod-migrate`'s `create_superuser` (and the API itself) fail at
+settings validation after the migrations have already applied.
+
+**Carry across from `backend/.env.prod`,** noting the renames:
+
+| old                                            | new                                                      |
+| ---------------------------------------------- | -------------------------------------------------------- |
+| `EMAIL_HOST` / `EMAIL_PORT` / `EMAIL_USERNAME` | `SMTP_HOST` / `SMTP_PORT` / `SMTP_USERNAME`              |
+| `SUPERUSER_EMAIL` / `SUPERUSER_NAME`           | `BOOTSTRAP_SUPERUSER_EMAIL` / `BOOTSTRAP_SUPERUSER_NAME` |
+| `BACKUP_DIR`                                   | `BACKUP_HOST_DIR`                                        |
+
+`LOKI_URL` has no replacement: **delete it.** Container logs no longer go to Loki
+directly — see the telemetry note below.
+
+**Upload quotas are now a pair of tiers, not one ceiling.** If the host's `.env`
+carries a raised `MAX_UPLOAD_FILES_PER_USER` from an earlier attempt at the
+lockout, reconsider it: that variable is now the *contributor* tier and applies
+to every external contributor. The lab account is covered by promotion (step 8b)
+and `MAX_UPLOAD_FILES_PER_LAB_USER` instead. A lab tier below its contributor
+counterpart fails settings validation and the stack will not start.
+
+Log labels changed with the collection path: what used to be Loki's
+`service,env,host` label set is now the OpenTelemetry resource attributes
+`service.name`, `env` and `project`. Existing Grafana queries filtering on
+`host=` need updating.
+
+> **Telemetry is one switch and two credentials now, not a pile of them.** Set
+> `OTEL_EXPORTER_OTLP_ENDPOINT=https://otlp.cml-relab.org`, `OTLP_AUTH_TOKEN`
+> (a bearer token from the monitoring stack operator) and `TELEMETRY_EDGE_KEY`
+> (the WAF-skip header value, below). The endpoint switch turns
+> on the API's own OpenTelemetry exporter **and** auto-includes
+> `compose.telemetry.yml`, a Grafana Alloy agent that forwards every other
+> container's stdout to the same endpoint. **Then run `./bootstrap.sh relab prod` on
+> the monitoring host as part of this step** — telemetry flowing and telemetry being
+> *watched* are two different things, and only the second one survives this host going
+> quiet. `just deploy-secrets-check` fails if
+> the endpoint is set without both credentials.
+>
+> Compose derives `OTEL_EXPORTER_OTLP_HEADERS` from the token, so the SDK's
+> percent-encoded header format is not something to get right by hand.
+>
+> `LOKI_PUSH_URL` and the Loki Docker-driver overlay are **gone**. Delete both
+> `LOKI_URL` and `LOKI_PUSH_URL` from the host's `.env`; nothing reads them. The
+> monitoring stack (github.com/CMLPlatform/monitoring) publishes only `grafana.`
+> and `otlp.` and deliberately exposes no Loki push hostname, because Loki has no
+> authentication of its own.
+>
+> Alloy also ships host metrics — CPU, memory, disk, network and `hwmon`
+> temperatures and fan speeds — over the same endpoint, so this host does not need
+> a separate host-monitoring agent. What it deliberately does NOT replace is the
+> per-job dead-man's switch: see "Alerting is two mechanisms" under Known
+> post-launch gaps, and [DEPLOY-PROD.md](DEPLOY-PROD.md) Part 1.5 for the standing
+> configuration.
+>
+> The Cloudflare firewall rule `relab_telemetry_ingress_skip_managed_security`
+> matches a separate `X-Telemetry-Key` header (never the bearer token —
+> ruleset expressions are readable through the Cloudflare API). Set
+> `TELEMETRY_EDGE_KEY` in this host's `.env` and supply the same value to
+> OpenTofu as `TF_VAR_telemetry_edge_key`. Rotate that pair together, or
+> telemetry keeps working while quietly losing its bot-product exemption; the
+> bearer token rotates independently with the collector.
+>
+> A wrong token shows up as `Failed to export logs batch code: 401, reason: Unauthorized` in the
+> API's own container log — the one telemetry failure that is loud rather than silent.
+
+**Delete these stale names:** `APP_ENV`, `COMPOSE_PROJECT_NAME`, `BUILD_MODE`,
+`CSP_API_ORIGIN`, `WEB_CONCURRENCY`, `BACKEND_API_URL`, `FRONTEND_APP_URL`,
+`DOCS_URL`, `OAUTH_ALLOWED_REDIRECT_URIS`, and any `RELAB_*_IMAGE` overrides
+(the release always builds locally and silently ignores them).
+
+Check it:
+
+```bash
+just env-policy-check
+just compose-config
+```
+
+### Two renames that have no code migrating them
+
+Both are one-time and manual on purpose: a shim carried in the repo for a
+transition that happens once outlives the transition and is never removed.
+
+**1. The WAF header — deploy the hosts, then apply OpenTofu. In that order.**
+
+The skip rule now matches `X-Telemetry-Key`; the hosts used to send
+`X-Relab-Telemetry-Key`. `infra/cloudflare-zone` is zone-global, so a single
+`tofu apply` lands on prod and staging together. Apply it while a host still sends
+the old name and that host's exports are bot-challenged — and a challenged export is
+dropped with no error anywhere, which is the failure this whole section exists to
+avoid. So:
+
+1. `just prod-up YES` and `just staging-up YES` on both hosts, on this release.
+2. Confirm both are sending: on the monitoring host,
+   `count({project="relab"})` is non-zero for `env="prod"` and `env="staging"`.
+3. Only then `just cloudflare-zone-apply YES`.
+
+Rolling back the deploy after step 3 reintroduces the old header and silently
+loses telemetry; roll the zone back with it.
+
+**2. The ping variables — rename them on each host before the next job fires.**
+
+`run_scheduled.sh` is vendored and carries no project prefix, so it reads `PING_*`
+where the units' env file still says `RELAB_PING_*`. An unset variable disables
+pinging *silently*, which is precisely what the dead-man's switch exists to prevent.
+On each host:
+
+```bash
+sudo sed -i 's/^RELAB_PING_/PING_/' /etc/relab/relab.env
+just timers-install prod        # re-render the units; warns if any URL is still unset
+just watchdog prod              # check 3b confirms all three resolve
+```
+
+`just timers-install` warns about missing *and* empty `PING_*` names, so a host
+skipped here reports itself the next time it is touched — and healthchecks.io fires
+its own "no ping received" alarm within the job's period regardless.
+
+______________________________________________________________________
+
+## 7. Stop the old stack — from the old checkout
+
+Five services were renamed (`docs-site`→`docs`, `app-site`→`app`,
+`web-site`→`www`, and `uploads-backup`+`postgres-backup`→`backup`). The new
+compose files do not know the old names, so stopping the stack from the old
+checkout is still the clean path.
+
+**Stop first, then switch:**
+
+```bash
+just prod-down YES backups          # still on the old revision
+docker ps -a | grep relab_prod      # must be empty of running containers
+```
+
+Only then:
+
+```bash
+git checkout <release-branch> && git pull --ff-only
+```
+
+If you switched too early, `just prod-down YES` now passes `--remove-orphans`
+and clears the renamed containers for you; verify with
+`docker ps -a | grep relab_prod`.
+
+______________________________________________________________________
+
+## 8. Build, start, migrate
+
+Images are built locally and pinned to `:prod-local` with no registry pull — a
+stale image silently runs the *old* code, so the rebuild is mandatory:
+
+```bash
+just prod-build
+```
+
+Confirm no seeding is enabled (`SEED_DUMMY_DATA`, `SEED_CPV_CATEGORIES`,
+`SEED_CPV_PRODUCT_TYPES`, `SEED_HS_CATEGORIES` unset or false) — the taxonomy
+seeds are not gated on an empty database.
+
+```bash
+just prod-up YES scanning   # drop `scanning` if you decided against ClamAV in 1a
+just prod-migrate YES
+```
+
+`prod-up` starts the database, cache, and (with the profile) ClamAV; expect the
+API to stay unhealthy for a few minutes on first boot while virus signatures
+download.
+`prod-migrate` runs every pending migration in one transaction, then always runs
+`create_superuser` (which only creates when absent — it will not reset your
+existing superuser's password).
+
+If the migration aborts, prod is untouched at `6f2b9e4a1c3d`. Fix the data
+(almost certainly a query-A email, or a query-G quantity/amount_in_parent row),
+and re-run.
+
+This two-command order means the API serves against the *old* schema between
+`prod-up` and `prod-migrate`. That is fine here — the cutover is a full outage
+behind a closed tunnel — but it is not fine for a routine release. For those,
+start the stack with the `migrations` profile instead and the API waits for the
+migrator to exit 0 before it starts:
+
+```bash
+just prod-up YES scanning migrations   # migrate, then serve, in one step
+```
+
+The dependency is declared `required: false`, so a profile-less `prod-up`
+behaves exactly as it always has. If the migration fails, the migrator exits
+non-zero and the API never starts — the schema and the code stay in step.
+
+Once the migration succeeds, backfill the byte-quota ledger (see the quota
+lockout note above; wraps the same script as `just backfill-upload-sizes`,
+which only exists locally, not in the container):
+
+```bash
+docker compose -p relab_prod --env-file .env --env-file deploy/env/prod.compose.env \
+  -f compose.yaml -f compose.deploy.yaml \
+  --profile migrations run --rm --entrypoint python \
+  migrator -m scripts.maintenance.backfill_upload_sizes
+```
+
+______________________________________________________________________
+
+## 8a. Encrypt the previously plaintext columns
+
+Only if step 0 found prod at `main` (or any revision without
+`DATA_ENCRYPTION_KEY`). `main` stores OAuth access/refresh tokens and YouTube
+broadcast keys as plaintext; the release expects them AES-256-GCM encrypted
+under `secrets/prod/data_encryption_key`. Until this runs, OAuth refresh and
+any YouTube flow will fail to read their stored values.
+
+Dry run first:
+
+```bash
+docker compose -p relab_prod --env-file .env --env-file deploy/env/prod.compose.env \
+  -f compose.yaml -f compose.deploy.yaml \
+  --profile migrations run --rm --entrypoint python \
+  migrator -m scripts.maintenance.migrate_encryption_v1_to_v2 --dry-run
+```
+
+If it reports no errors, run it for real by dropping `--dry-run`. It is a
+one-time pass tied to the key created in step 4 — losing that key makes the
+encrypted columns unrecoverable.
+
+______________________________________________________________________
+
+## 8b. Promote the lab accounts — before anyone tries to upload
+
+The role model (added 2026-08-18) backfills **every** existing account to
+`contributor`, deliberately: the migration cannot know who the lab is, and
+guessing high would hand lab storage to every external contributor. So until
+this step runs, the account holding the bulk of prod's media is over its tier
+and cannot upload (see the quota lockout note in step 3).
+
+Find who is affected. This reads the ledger *after* the backfill, so it is the
+authoritative list rather than query E's estimate:
+
+```bash
+docker compose -p relab_prod --env-file .env --env-file deploy/env/prod.compose.env \
+  -f compose.yaml -f compose.deploy.yaml \
+  --profile migrations run --rm --entrypoint python \
+  migrator -m scripts.maintenance.list_accounts_over_contributor_quota
+```
+
+It logs one line per account that is over the quota its current role grants,
+**by id only** — no email or username reaches those logs. An empty report means
+nothing is locked out and this step is a no-op.
+
+Promote through the admin API, which audit-logs the change. As a superuser with
+a bearer token:
+
+```bash
+curl -fsS -X PUT https://api.cml-relab.org/v1/admin/users/<user_id>/role \
+  -H "Authorization: Bearer $TOKEN" \
+  -H 'Content-Type: application/json' \
+  -d '{"role": "lab"}'
+```
+
+If the tunnel is still closed at this point in the window, the same change by
+SQL is acceptable — it skips the audit event, so note in the launch record that
+it was done this way and why:
+
+```sql
+UPDATE "user" SET role = 'lab' WHERE id = '<user_id>';
+```
+
+Re-run the report; it must come back empty before you proceed. Then confirm the
+tiers are what you intended:
+
+```sql
+SELECT role, count(*), max(upload_file_count) AS max_files, max(upload_total_bytes) AS max_bytes
+FROM "user" GROUP BY role;
+```
+
+`role` accepts only `contributor` and `lab` — a `ck_user_role_valid` check
+constraint rejects anything else, so a typo in the SQL form fails loudly rather
+than creating a third tier nothing enforces.
+
+______________________________________________________________________
+
+## 9. Verify before declaring success
+
+```sql
+SELECT version_num FROM alembic_version;      -- must equal `alembic heads` for
+                                              -- the release checkout, NOT the
+                                              -- stale f1a2b3c4d5e6 above
+
+-- Compare against the step 3 baseline (query F).
+SELECT (SELECT count(*) FROM product WHERE parent_id IS NULL)     AS base_products,
+       (SELECT count(*) FROM product WHERE parent_id IS NOT NULL) AS components,
+       (SELECT count(*) FROM image)                               AS images,
+       (SELECT count(*) FROM file)                                AS files,
+       (SELECT count(*) FROM "user")                              AS users,
+       (SELECT count(*) FROM oauthaccount)                        AS oauth_links;
+
+-- Circularity notes: 'populated' must equal query C, and no empty objects.
+SELECT count(*) FILTER (WHERE circularity_properties IS NOT NULL)   AS populated,
+       count(*) FILTER (WHERE circularity_properties = '{}'::jsonb) AS empty_objects
+FROM product;
+SELECT id, jsonb_pretty(circularity_properties) FROM product
+WHERE circularity_properties IS NOT NULL LIMIT 5;   -- comments/refs should be folded in
+
+-- Email canonicalization complete and unique: all three equal.
+SELECT count(*), count(email_canonical), count(DISTINCT email_canonical) FROM "user";
+
+-- No orphaned media.
+SELECT count(*) FROM image i WHERE i.parent_type='PRODUCT'
+  AND NOT EXISTS (SELECT 1 FROM product p WHERE p.id = i.parent_id);   -- 0
+
+-- Quota ledger: file counts real, bytes real once step 8's backfill has run.
+SELECT sum(upload_file_count), sum(upload_total_bytes), max(upload_file_count) FROM "user";
+
+-- Roles: every account is `contributor` unless step 8b promoted it, and nobody
+-- is left above the tier they now hold (this must return 0 rows).
+SELECT role, count(*) FROM "user" GROUP BY role;
+SELECT id, role, upload_file_count FROM "user"
+WHERE (role = 'contributor' AND upload_file_count > 1000)
+   OR (role = 'lab'         AND upload_file_count > 20000);
+-- Compare the thresholds against the host's own MAX_UPLOAD_FILES_PER_* values
+-- if they were overridden in the root .env.
+
+ANALYZE product; ANALYZE "user"; ANALYZE image; ANALYZE file;
+```
+
+The `ANALYZE` matters more than it looks: the release adds trigram, composite
+and partial indexes that the planner will not choose until it has statistics
+for them. Confirm they are actually used rather than assuming — on real data,
+not on the empty dev database where every plan is a sequential scan anyway:
+
+```sql
+-- Trigram search must reach the index, not fall back to a scan. A Seq Scan here
+-- means a query is comparing a wrapped column (lower(name)) against an index
+-- built on the bare one.
+EXPLAIN SELECT id FROM product WHERE name % 'drill';
+
+-- The product thumbnail subquery must read one index entry, with no Sort node
+-- above the image scan.
+EXPLAIN SELECT p.id, (SELECT i.file FROM image i
+                      WHERE i.parent_type='PRODUCT' AND i.parent_id=p.id
+                      ORDER BY i.created_at LIMIT 1)
+FROM product p ORDER BY p.id LIMIT 50;
+```
+
+Then re-measure the API itself against the prod-shaped dataset, since the
+list-endpoint work only shows up at real row counts. Needs `k6` on the host,
+and the run is read-only — two virtual users against public GET paths:
+
+```bash
+cd backend
+BASE_URL=https://api.cml-relab.org just perf-baseline
+```
+
+It writes `backend/reports/performance/latest-k6-summary.json`. Record the
+`product_list_read` p95 next to the counts from the step 3 baseline — that is the
+reference point for the next release that touches a read path, and the only
+place these numbers exist for prod-shaped data.
+
+Then exercise the real paths:
+
+```bash
+curl -fsS https://api.cml-relab.org/live
+curl -fsS https://api.cml-relab.org/health
+```
+
+Every public origin, not just the API — a healthy API behind a broken tunnel
+route still reads as a failed launch to everyone else:
+
+```bash
+curl -fsS -o /dev/null -w '%{http_code} %{url_effective}\n' \
+  https://api.cml-relab.org/live \
+  https://api.cml-relab.org/health \
+  https://app.cml-relab.org/ \
+  https://cml-relab.org/ \
+  https://docs.cml-relab.org/
+```
+
+No container may be restarting or unhealthy — the API in particular reports
+`unhealthy` whenever Postgres or Redis is unreachable, which is the failure this
+catches before a user does:
+
+```bash
+docker compose -p relab_prod ps --format '{{.Service}}\t{{.Status}}'
+```
+
+Two host-level checks that nothing else covers:
+
+```bash
+# Log rotation. Docker's default is UNBOUNDED json-file logging; the per-service caps
+# in compose.deploy.yaml are the rotation control the repo enforces, with the host
+# daemon.json log-opts (DEPLOY-PROD.md Part 1.0) as an optional fallback for
+# containers outside the stack. Every service must report max-size — a service
+# without it fills the disk on its first crash loop.
+docker compose -p relab_prod ps -q | xargs docker inspect \
+  --format '{{.Name}} {{json .HostConfig.LogConfig.Config}}' \
+  # every line must show "max-size":"10m"; an empty {} is a finding, not noise
+
+# Telemetry actually leaving the host. Alloy fails loudly on a bad token or a
+# challenged edge (the WAF-skip rule matches TELEMETRY_EDGE_KEY — if the zone rule
+# and the host .env disagree, exports are bot-challenged and dropped). Zero matches
+# is the pass condition.
+docker logs --since 10m "$(docker compose -p relab_prod ps -q alloy)" 2>&1 \
+  | grep -Ei 'error|failed|401|403' || echo "alloy: no export errors"
+```
+
+By hand: log in with Google **and** GitHub (the GitHub client changed in this
+release), open a product with images, and **upload one image as the lab account
+that owns the bulk of the media** — any other account has a near-empty ledger
+and would pass the quota check without proving anything. If that account was
+promoted in step 8b, also confirm the "Research files" block is visible on one
+of its records: it renders only for `lab`, so its absence means the promotion
+did not take.
+
+### Go / no-go
+
+There is no automated gate and nothing pages anyone, so this is a deliberate
+decision a human makes, once, out loud. **Go** requires all of:
+
+- `alembic_version` equals the release checkout's `alembic heads`, and every
+  count above matches the step 3 baseline,
+- all five origins return 2xx and no container is restarting or unhealthy,
+- both OAuth providers, a product page, and one image upload **by the lab
+  account** work by hand,
+- the over-quota report from step 8b comes back empty.
+
+Anything unresolved is **no-go**: roll back with §12 and retry in a later
+window. Do not launch "mostly working" and fix forward — the pre-upgrade dump
+gets less useful the longer prod accepts writes on the new schema.
+
+______________________________________________________________________
+
+## 10. Set up backups
+
+The full procedure — repository, timer, offsite credential, monitoring crons — is
+**[DEPLOY-PROD.md](DEPLOY-PROD.md) Part 1**. It is standing host setup, not cutover
+work, and it stays after this runbook is deleted. Do it now, then come back.
+
+Only two things are specific to this cutover:
+
+- **This is first-time setup, not a re-enable.** `main` has no restic tooling at all,
+  so there are no pre-existing snapshots and nothing to migrate. The old plain-copy
+  backup directory was preserved in §2; it is not readable by the new tooling, so keep
+  it until §0b's abort conditions are all satisfied.
+
+- **Retire the old backup container if the host ever ran one.** Compose does not remove
+  a container whose profile went away, so it would keep running beside the new timer:
+
+  ```bash
+  docker compose -p relab_prod --env-file .env --env-file deploy/env/prod.compose.env \
+    -f compose.yaml -f compose.deploy.yaml --profile backups rm -sf backup
+  ```
+
+- **Reclaim `/var` once the old directory is genuinely dead.** The plain-copy backups
+  are the largest thing on that filesystem and they are not small: as of 2026-08-27 the
+  host carried 25.5 GB under `/var/backups/relab` — 9 daily, 4 weekly and 6
+  monthly `user_uploads` tarballs at ~1.5 GB each — against 12.1 GB free on an 86 GB
+  `/var`. The daily tier grows 1.5 GB a day and showed no sign of pruning, so the
+  headroom is a matter of days, and a full `/var` takes Docker, Loki, Tempo and
+  Prometheus down together on that host.
+
+  These are full tarballs, not incrementals, which is most of why they are that large;
+  restic dedup should collapse the same history to a fraction. Delete the old directory
+  only when all of these hold, in order:
+
+  1. `just restore-check prod` passes against a restic snapshot;
+  1. every §0b abort condition is satisfied, so there is no path back that needs the
+     old copies;
+  1. at least one restic snapshot has been verified **offsite** — the point of the
+     migration is that the backup does not share a disk with the thing it protects.
+
+  Until all three hold, keep them and free space elsewhere instead.
+
+Do not declare this step done until `just restore-check prod` passes — §0b
+depends on it.
+
+______________________________________________________________________
+
+## 11. Cloudflare — prod is still unadopted; do nothing for prod
+
+**Do not run `just cloudflare-apply prod`** during or after this cutover.
+
+Live traffic depends only on `CLOUDFLARE_TUNNEL_TOKEN` being set in the root
+`.env` for the `cloudflared` service. It does not depend on this Terraform, and
+importing does not change or reissue that token.
+
+`just cloudflare-check` remains safe at any time — it verifies a throwaway copy
+of each root, so it needs no credentials, no network, and no state access.
+
+### What is adopted, as of 2026-08-19
+
+| Root                     | Workspace | Status                                                                                                   |
+| ------------------------ | --------- | -------------------------------------------------------------------------------------------------------- |
+| `infra/cloudflare-zone/` | `default` | **Adopted and applied.** TLS settings, cache and firewall rulesets imported; rate-limit ruleset created. |
+| `infra/cloudflare/`      | `staging` | **Adopted and applied.** Its tunnel now answers to `relab-staging`, renamed from `cml-relab-test`.       |
+| `infra/cloudflare/`      | `prod`    | **Nothing.** No workspace, no state.                                                                     |
+
+Confirm rather than trust this table — it records one day's observation:
+
+```bash
+just cloudflare-plan staging     # a plan, not an apply
+just cloudflare-zone-plan
+```
+
+### Three things the staging adoption taught, that prod will meet too
+
+- **The live tunnels carry their original names.** Staging's was
+  `cml-relab-test` while the module computes `relab-${environment}`, so applying
+  **renames** it, and staging's apply did exactly that. The rename is safe — the
+  tunnel id is unchanged and `cloudflared` authenticates by id and secret, not
+  name — but it is a real change. Prod's tunnel is `cml-relab-prod`
+  (`9f5762a9-…`), so adopting prod will rename it to `relab-prod`. The account
+  also holds tunnels this repo does not manage (`cml-monitoring`, the `ssh-…`
+  and `cml-rpi5-…` ones); leave them alone.
+
+- **Zone-scoped resources are shared.** prod and staging share
+  `cml-relab.org`, so the TLS settings and the three entrypoint rulesets affect
+  both environments at once. They now live in `infra/cloudflare-zone/` with a
+  single owner, which is why prod's own import list is just six per-environment
+  resources. The zone was found at TLS 1.0 and is now at 1.2, for every hostname
+  including prod's.
+
+- **This zone's Cloudflare plan is restrictive, and it fails at apply time.**
+  The `http_ratelimit` phase allows one rule, a 10s counting period and a 10s
+  mitigation timeout, and neither the `matches` operator nor `http.host` may be
+  used in it. Each of those refusals landed *partway through* an apply, after
+  earlier resources had already changed. They are asserted in
+  `infra/cloudflare-zone/tests/` now, so `just cloudflare-check` catches a
+  regression instead of an apply doing it live.
+
+### Adopting prod, as separate work outside any window
+
+No `prod` workspace exists, so a plan today would show every resource as a
+*create*: duplicate DNS records, a **second** tunnel whose id does not match the
+live `CLOUDFLARE_TUNNEL_TOKEN`, and a replacement for the rulesets that protect
+prod right now.
+
+Generate the import blocks rather than writing them by hand:
+
+```bash
+cd infra/cloudflare
+./generate-imports.sh edge prod > imports.tf
+cat imports.tf                       # review before running anything
+just cloudflare-plan prod            # must show 0 to add, 0 to destroy
+```
+
+If it reports no tunnel by the expected names, it lists every tunnel in the
+account with its id and connection count; re-run with
+`RELAB_TUNNEL_NAME='<name>'` once you know which one serves prod.
+
+Delete `imports.tf` once the apply succeeds — import blocks re-run on every plan
+until removed, and they make `tofu test` unusable while present.
+
+`infra/cloudflare/README.md` carries the token scopes, where state lives, the
+state-encryption rules, and the full import workflow.
+
+______________________________________________________________________
+
+## 12. Rollback
+
+If verification fails and the release cannot be trusted:
+
+1. `just prod-down YES backups` from the release checkout.
+
+1. `git checkout main`.
+
+1. Restore the database from `~/relab-cutover/prod-pre-mvp.dump`:
+
+   ```bash
+   docker compose -p relab_prod exec -T postgres \
+     pg_restore --clean --if-exists --no-owner -U "$PGSUPERUSER" -d relab_db \
+     < ~/relab-cutover/prod-pre-mvp.dump
+   ```
+
+1. Restore uploads from `user_uploads-pre-mvp.tar.gz` if anything wrote to them.
+
+1. `just prod-up YES scanning` on `main` (drop `scanning` if you disabled
+   it in 1a; the backup service is timer-driven, not part of `up`).
+
+`just prod-build` also tags each image it builds with the commit it was built
+from (`relab-backend:prod-<sha>` alongside `relab-backend:prod-local`), so
+rolling back to the previous build needs no rebuild — per image:
+
+```bash
+docker tag relab-backend:prod-<oldsha> relab-backend:prod-local
+just prod-up YES scanning   # drop `scanning` only if you disabled it in 1a
+```
+
+The schema has no scripted down-migration path for the dropped data: the
+`downgrade()` functions restore column *shape* but not content. The dump from
+step 2 is the real recovery mechanism, which is why step 0 forbids deleting it
+early.
+
+## Known post-launch gaps
+
+Accepted risks, not blockers — but they are accepted by a person, not by
+default. Owner: the deploy operator, who is also the one making the go/no-go
+call in §9. Do not discover these by surprise:
+
+- **No scripted schema rollback.** All 40 migrations define `downgrade()`, and
+  `test_migrations_downgrade_upgrade` proves the newest one round-trips — but on
+  an empty schema, one step only. Nothing tests a multi-step downgrade or data
+  preservation, and a downgrade that re-adds a dropped column re-adds it empty.
+  The §2 dump is the only data rollback; §12 is the only rehearsed path.
+
+- **Rate-limit buckets reset once at this deploy.** The rate-limiter's HMAC
+  signing key moved to `cache_signing_secret`, so every existing bucket key
+  changes and in-flight windows restart from zero. Harmless (limits are
+  short-lived), but do not read a post-deploy lull in 429s as a real change in
+  traffic.
+
+- **Alerting is two mechanisms, deliberately.** Everything observable — container logs,
+  host metrics, application traces — goes to the central Grafana stack. One thing does
+  not: a per-job dead-man's switch that pushes from this host to healthchecks.io, so a
+  dead host, a dead collector or a broken tunnel still produces an alarm rather than
+  silence that looks like health. `just watchdog prod` is the local check whose exit
+  code that ping reports. Setup for both is standing configuration that outlives this
+  runbook — see [DEPLOY-PROD.md](DEPLOY-PROD.md) Parts 1.2, 1.4 and 1.5.
+
+- **This cutover is start-then-migrate.** The §8 commands bring the API up
+  against the old schema before `prod-migrate` runs. Harmless here because you
+  are taking a full outage. For routine releases, pass the `migrations` profile
+  to `prod-up` instead and the API waits for the migrator to exit 0 (see §8) —
+  that closes the window but is still not a zero-downtime deploy, since the API
+  is down for the length of the migration.

+# Staging cutover: `main` → the MVP release
+
+The one-time migration of the **staging** host, and what is still owed on it.
+Prod equivalent: [CUTOVER-PROD.md](CUTOVER-PROD.md). Standing setup and routine
+releases live in [DEPLOY-STAGING.md](DEPLOY-STAGING.md), which outlives this file —
+this one is deleted once the outstanding items below are done.
+
+Staging is further along than prod — it already runs the release layout, so most of
+CUTOVER-PROD's steps are done here. What remains is listed under **Outstanding**.
+Staging shares `compose.deploy.yaml` with prod, so anything unfinished here is also
+unrehearsed for prod.
+
+State below verified **2026-08-19**. Re-check rather than trusting it.

+| Local repo       | `${BACKUP_HOST_DIR}/restic`, 18 snapshots after the first working prune                              |
+| Offsite          | `rclone:surfdrive_staging:` — a SURFdrive share link scoped to staging's folder                      |
+| Credential       | `secrets/staging/rclone.conf`, remote `surfdrive_staging` (share token, not an account app password) |
+| Watchdog         | Host cron, daily at 08:30                                                                            |
+
+The backup path was rebuilt on 2026-08-19 after a failed offsite copy put the old
+long-running container into a 19-hour restart loop: it re-ran a full backup every
+~15 s, and every monitor read green throughout because the only check was snapshot
+*age*, which a crash loop makes look better than healthy. Backups are now a
+systemd one-shot, so a failure is recorded rather than retried instantly.
+
+## Outstanding
+
+### 1. Install the scheduled-job timers
+
+The host currently runs an older single backup unit plus a daily watchdog cron. Both are
+superseded by three systemd timers — backup, watchdog, and monthly restore verification
+— installed in one step:
+
+```bash
+just timers-install staging
+```
+
+Then fill in `/etc/relab/relab.env` with three healthchecks.io URLs (one per job; a
+shared check cannot tell you which job went quiet), and **remove the old watchdog line
+from `crontab -e`** — the timer replaces it, and leaving both means duplicate pings.
+
+Verify:
+
+```bash
+systemctl list-timers 'relab-*@staging.timer' --all
+just watchdog staging
+```
+
+### 2. Commit the working tree
+
+`just watchdog staging` currently exits non-zero on `deploy checkout has uncommitted changes` — correctly. That alert stays red, and masks real ones, until the backup rework
+is committed.
+
+### 3. Prod's share-link credential
+
+Staging now uses a SURFdrive share link scoped to its own folder, so staging cannot
+reach prod's repository. Prod needs the same treatment before it deploys: its own
+share link, remote named `surfdrive_prod`, per
+[DEPLOY-PROD.md](DEPLOY-PROD.md) Part 1.3. `just deploy-secrets-check` reports it as
+missing until then, and backups run local-only in the meantime.
+
+### 4. Confirm a timer-driven run of each job
+
+The backup timer has already fired successfully through systemd (`Result=success`).
+The watchdog and restore-check timers are new and have not:
+
+```bash
+systemctl list-timers 'relab-*@staging.timer' --all
+for j in backup watchdog restore-check; do
+  printf '%s: %s\n' "$j" "$(systemctl show relab-$j@staging.service -p Result --value)"
+done
+```
+
+## Not yet rehearsed
+
+- **Prod runs on a different machine**, so nothing here exercises the prod half of
+  CUTOVER-PROD. Every step verified on this host is verified for the *procedure*
+  only; none of it has run against prod's data, volumes, or secrets.
+- **`secrets/prod/rclone.conf` is still a placeholder.** `just deploy-secrets-check`
+  reports it. Prod backups will run locally and skip the offsite copy with a warning
+  until it is written — deliberately, so an unconfigured credential does not leave
+  the alert permanently red.
+- **A full rebuild from an empty volume** has not been done since the rework. See
+  the last section of [DEPLOY-STAGING.md](DEPLOY-STAGING.md); staging is the only
+  host where that test is cheap.

+# Operating the production host
+
+Everything needed to run prod: one-time host setup, the routine release loop, and
+recovery. Self-contained — nothing here depends on the cutover runbooks, which are
+deleted once the MVP migration is done.
+
+Staging equivalent: [DEPLOY-STAGING.md](DEPLOY-STAGING.md). Rehearse there first.
+
+______________________________________________________________________
+
+## Part 1 — First-time host setup
+
+Once per machine, not per release. `just watchdog prod` reports each of these as a
+distinct alert if it is missing, so an incomplete setup is not silent.
+
+### 1.0 Docker daemon log rotation (fallback)
+
+The Compose files cap every stack service's logs (`max-size: 10m`, `max-file: 3`),
+and that is the control the repo can enforce. Set the same defaults host-wide as a
+fallback, so a container started OUTSIDE the stack — a debug `docker run`, a future
+second project — cannot fill the disk either. Merge into `/etc/docker/daemon.json`
+(CML hosts already have one for the nvidia runtime; add the key, don't replace the
+file) and restart dockerd in a maintenance moment — daemon defaults apply only to
+containers created afterwards:
+
+```json
+"log-driver": "json-file",
+"log-opts": { "max-size": "10m", "max-file": "3" }
+```
+
+Skipping this loses nothing for the stack itself; the compose caps stay authoritative.
+
+### 1.1 Backup repository
+
+Create the bind-mount directory **before** first use. If Docker creates it, it comes
+up root-owned and the backup container (uid 1001) cannot initialize the repository:
+
+```bash
+mkdir -p "${BACKUP_HOST_DIR:-./backups}/restic"
+sudo chown -R 1001:1001 "${BACKUP_HOST_DIR:-./backups}"
+
+just backup prod             # initializes the repo and takes the first snapshot
+just restore-check prod   # needs that snapshot to exist
+```
+
+The repository is encrypted with `secrets/prod/restic_password`. **Never rotate it** —
+every later snapshot depends on it.
+
+`BACKUP_HOST_DIR` is one value shared by every stack on the host, so two environments
+co-located on one machine would share a restic directory. It fails closed rather than
+corrupting, but only one of them gets backups. Give each host a single environment.
+
+### 1.2 Scheduled jobs
+
+Three jobs run on a schedule: the nightly backup, an hourly watchdog, and a monthly
+restore verification. All three are systemd timers — one mechanism, one place to look
+(`systemctl list-timers`), and catch-up after downtime where it matters.
+
+```bash
+just timers-render            # inspect what will be installed
+just timers-install prod      # render, install, enable, start (needs sudo)
+```
+
+`docker compose up` does **not** start backups; the backup service is a one-shot that
+the timer runs and that exits. The committed units carry placeholders — the installer
+substitutes this checkout, the deploy user, and the `just` location, the last because
+systemd runs without a login `PATH`.
+
+| Job                        | When             | Catch-up                                                 |
+| -------------------------- | ---------------- | -------------------------------------------------------- |
+| `relab-backup@prod`        | 02:30 daily      | yes — a night missed while the host was off runs at boot |
+| `relab-watchdog@prod`      | hourly           | no — a missed check self-heals within the hour           |
+| `relab-restore-check@prod` | 03:40 on the 1st | yes — this is why it is a timer and not cron             |
+
+That last row is the reason not to use cron here: a monthly job skipped because the host
+was down on the 1st would not run again for two months, and it is the only check that
+proves a snapshot actually restores rather than merely exists.
+
+### How a failed job reaches you
+
+The installer seeds `/etc/relab/relab.env` (mode 0600, never committed) with one
+dead-man's-switch URL per job. Fill them in from healthchecks.io — one check per job,
+because sharing a URL lets the hourly job's pings mask the monthly job's silence:
+
+```ini
+PING_BACKUP=https://hc-ping.com/...          # period 1 day
+PING_WATCHDOG=https://hc-ping.com/...        # period 1 hour
+PING_RESTORE_CHECK=https://hc-ping.com/...   # period 35 days
+```
+
+Each job pings on success, and on failure pings `/fail` with its own output as the body,
+so the alert carries the reason. An empty URL disables that job's ping without failing
+the job.
+
+**Why this exists when everything else goes to Grafana.** Every other signal — container
+logs, host metrics, application traces — leaves this host through Alloy to the central
+collector. That means a dead host, a dead collector, a broken tunnel and an expired token
+all look identical from Grafana: silence. The ping is a push *from* the host *to* an
+outside endpoint, so it is the one mechanism that still reports when the observability
+pipeline is itself the thing that broke. Its absence is the alarm, which is the failure
+mode neither `MAILTO` nor a dashboard can report.
+
+Keep it minimal on purpose. It carries no credentials beyond the URL, has nothing to
+operate, and is not a second monitoring system — it answers exactly one question: *did
+this job run and succeed?* Everything else belongs in Grafana.
+
+Note the failure body puts job output — hostnames, paths, restic summaries — in a third
+party's hands. That is the deliberate trade for an alert that names its own cause.
+
+The deploy user needs docker-group membership, which is root-equivalent: these units run
+a writable git checkout as unattended, scheduled, root-level jobs. Treat that directory
+as privileged.
+
+### 1.3 Offsite copy
+
+SURFdrive over WebDAV, reached with a **share-link credential scoped to one folder**,
+not an account app password. App passwords grant whole-account access, so two of them
+would give staging delete authority over production's only off-host copy. A share link
+cannot leave its folder. Verified working on SURFdrive 2026-08-19.
+
+In SURFdrive: create prod's folder, share it as a link with **edit** permission, set a
+share password, leave expiry **off** (an expiring link stops backups silently). The
+token is the last path segment of the share URL.
+
+Then write `secrets/prod/rclone.conf` (`just deploy-secrets-template prod` seeds a
+placeholder). The remote **must** be named `surfdrive_prod`:
+
+```ini
+[surfdrive_prod]
+type = webdav
+url = https://surfdrive.surf.nl/public.php/webdav
+vendor = nextcloud
+user = <share token — the token only, NOT the full share URL>
+pass = <output of: rclone obscure '<share password>'>
+```
+
+Three details fail differently, and two fail **quietly**:
+
+- `pass` must be obscured (`rclone obscure`), not plaintext. Fails loudly.
+- `user` is the token alone. The full share URL gives a 401.
+- `RESTIC_OFFSITE_REPOSITORY` is `rclone:surfdrive_prod:` with an **empty path**,
+  because a share link's WebDAV root *is* the shared folder. Appending a path creates a
+  second empty repository nested inside the real one and backs up into it — succeeding,
+  and reporting success, while the real archive sits untouched one level up.
+
+The remote *name* carries the environment because the path no longer can. If staging's
+`rclone.conf` reaches this host, `rclone:surfdrive_prod:` fails with "remote not found"
+instead of writing prod snapshots into staging's repository. The value is committed in
+`deploy/env/prod.compose.env`; never set it in the root `.env`, which is shared by every
+stack on the host.
+
+```bash
+just deploy-secrets-check   # reports if the remote is still undefined
+```
+
+Until the remote is defined, each run logs a loud WARNING, **skips the offsite copy and
+still succeeds** — deliberately, so a missing credential does not leave the alert
+permanently red, which is the same as no alert. For an on-demand copy outside the
+nightly cycle: `just backup-offsite-copy prod`.
+
+> If you add periodic `restic check --read-data-subset`: there is **no official cadence
+> recommendation** for it. The commonly repeated "1/12 monthly" is forum folklore, not
+> upstream guidance. Pick a cadence, write down why you picked it, and treat the number
+> as arbitrary-but-declared rather than authoritative.
+
+**This does not give immutability.** restic must delete in order to prune, so no
+credential arrangement makes the offsite copy append-only. A compromised share token can
+erase prod's off-host backups, leaving the local repository as the only copy. Object-lock
+storage (B2, Wasabi, S3) or a restic REST server with `--append-only` is the only real
+defence; WebDAV is neither.
+
+### 1.4 What the watchdog checks
+
+`just watchdog prod` — run hourly by the timer above, and worth running by hand after
+any change — checks every stack service (running, and healthy where a healthcheck
+exists), newest snapshot age, all three scheduled-job timers (installed, enabled,
+active, last run not failed), that the `PING_*` URLs are actually filled in, and
+deployment drift (uncommitted changes, or commits that exist nowhere else). It exits
+non-zero with one `ALERT[...]` line per problem.
+
+Its exit code is what the hourly dead-man's switch reports, so a failing check surfaces
+as a missed or failed ping rather than as a line nobody reads.
+
+**Do not delete the service-health, snapshot-age or timer checks until the central
+monitoring stack's `ProjectTelemetrySilent` and container-lifecycle rules are live and
+verified for this environment** — live meaning bootstrap has been run for it (§1.5
+below), not merely that the stack has the rules. Until then this script is the only
+detector for those failures; deleting a weak local signal before its central replacement
+exists trades a weak signal for none. See CMLPlatform/monitoring, ADR 0002.
+
+### 1.5 Telemetry
+
+Set these four in the host's root `.env` — endpoint and token from the monitoring stack
+operator (github.com/CMLPlatform/monitoring), the edge key shared with whoever runs
+`infra/cloudflare-zone` (`TF_VAR_telemetry_edge_key` must carry the same value):
+
+```env
+OTEL_EXPORTER_OTLP_ENDPOINT=https://otlp.cml-relab.org
+OTLP_AUTH_TOKEN=<bearer token>
+TELEMETRY_EDGE_KEY=<edge key>
+OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf
+```
+
+The endpoint is the on/off switch for the whole telemetry path. Setting it turns on the
+API's own OpenTelemetry exporter **and** auto-includes `compose.telemetry.yml`, a
+Grafana Alloy agent that ships two things the API cannot report about itself:
+
+- **container stdout** from every other service — postgres, redis, cloudflared, the
+  three frontends, the backup one-shot — as logs, labelled by Compose service name;
+- **host metrics** — CPU, memory, load, disk, network, and `hwmon` temperatures and fan
+  speeds. That last one is not decoration: the incident that produced these runbooks was
+  a backup crash-looping for 19 hours, noticed by ear from fan noise while every monitor
+  read green.
+
+**Then run `./bootstrap.sh <project> <env>` on the monitoring host — in the same change,
+not afterwards.** Setting the endpoint above starts telemetry flowing; bootstrap is what
+creates the rule that notices when it *stops*. A host can ship perfect telemetry and be
+completely unmonitored, because the detector for its silence lives on the other side.
+Skipping this is the one failure this whole design exists to prevent, and it leaves no
+trace on this host — nothing here can tell you the safety net is missing.
+
+The arguments must match `PROJECT` and `ENVIRONMENT` from
+`deploy/env/<env>.compose.env`, since those are the label values the rule matches on.
+Bootstrap also prints the `.env` block and the commands that vendor the agent files at a
+pinned tag, so run it before wiring this host rather than after.
+
+One token, two consumers: Compose folds it into the SDK's percent-encoded header format
+for the API, and Alloy reads it directly. There is no separate Loki push hostname — the
+monitoring stack does not publish one, because Loki has no authentication of its own.
+
+Alloy never touches the Docker socket: a `docker-socket-proxy` container holds it and
+exposes only the read-only endpoints discovery and log tailing need (containers, events,
+info, version, ping) over an internal network, with POST refused — nothing behind the
+proxy can start or exec a container. Alloy does mount the host's `/proc`, `/sys` and `/`
+(read-only) for node metrics, running as root with the capability set dropped to
+`SYSLOG` + `DAC_READ_SEARCH`. The `/rootfs` read access is still a real grant, but it is
+no more than a host-installed node_exporter running as root already has, and it is worth
+knowing rather than discovering.
+
+On a host with an NVIDIA card, add `GPU_METRICS=1` as well. That is the entire GPU
+setup: the deploy recipes then include `compose.telemetry.gpu.yml`, Alloy discovers the exporter
+over the Compose network and scrapes it, and utilisation, VRAM, temperature, power,
+throttle reasons and XID faults start arriving under the same `host_name`. Nothing else
+changes — a GPU host is one extra overlay, not a different design.
+
+Verify the whole path end to end with a real job, which is also the fastest way to prove
+discovery, labelling and export at once:
+
+```bash
+just backup prod
+```
+
+Then look for `service.name=backup` and the line `Backup run completed` in Grafana.
+
+______________________________________________________________________
+
+## Part 2 — Routine release
+
+```bash
+cd /path/to/relab
+git fetch origin && git checkout main && git pull --ff-only
+
+just prod-build                        # add `scanning` if ClamAV is enabled
+just prod-up YES scanning migrations   # migrator runs, THEN the API starts
+```
+
+Before you start: CI green on `main`, you know whether the release contains migrations
+(`cd backend && uv run alembic history -r <current>:head`), and you have a fresh backup
+(`just backup prod`).
+
+The `migrations` profile is the routine path: the API waits for the migrator to exit 0,
+so a failed migration leaves the old API serving rather than starting a new one against
+a schema that never changed. Without it you get a two-step that briefly serves against
+the old schema — acceptable during a planned outage, not for a routine release.
+
+Drop `scanning` only if `MALWARE_SCAN_ENABLED=false` in the root `.env`; `prod-up`
+refuses to start on the mismatch rather than failing uploads closed at runtime.
+
+### Verify
+
+```bash
+just watchdog prod
+just prod-logs        # ^C once it looks clean
+```
+
+Then exercise by hand what automation cannot: one upload, one OAuth login, one product
+page. Those three cover the paths most likely to break silently.
+
+______________________________________________________________________
+
+## Part 3 — Recovery
+
+Migrations run in a single transaction, so a failed migrate leaves the schema untouched
+at its previous revision. Fix forward where possible.
+
+Code-only rollback, when the release added no migrations (or the new schema still suits
+the old code). Every `just prod-build` also tags the result with the commit sha, so
+rolling back is a `docker tag` rather than a rebuild:
+
+```bash
+docker images 'relab-*' --format '{{.Repository}}:{{.Tag}}' | grep prod-   # find the sha
+for svc in backend www docs app; do
+  docker tag "relab-$svc:prod-<sha>" "relab-$svc:prod-local"
+done
+just prod-up YES scanning
+```
+
+Or rebuild from the previous source, which is slower but needs no tag bookkeeping:
+
+```bash
+git checkout <previous-tag>
+just prod-build && just prod-up YES scanning
+```
+
+Otherwise the backup is the recovery path:
+
+```bash
+just restore-check prod    # proves the snapshot loads, into a scratch DB
+```
+
+For a real restore, stop the stack, restore the dump into the live database, and bring
+it back up — rehearse this before you need it, using the smoke test as the template.
+
+Do not run `just cloudflare-apply prod` as part of a deploy. The edge is managed
+separately, and prod's adoption state is its own decision.

+# Operating the staging host
+
+Everything needed to run staging. Self-contained — nothing here depends on the
+cutover runbooks, which are deleted once the MVP migration is done.
+
+Staging shares `compose.deploy.yaml` with production, so this doubles as the
+rehearsal for [DEPLOY-PROD.md](DEPLOY-PROD.md): a step that has only ever run on prod
+has never actually been tested.
+
+______________________________________________________________________
+
+## Part 1 — First-time host setup
+
+Identical in shape to [DEPLOY-PROD.md](DEPLOY-PROD.md) Part 1, with `staging`
+substituted for `prod` throughout. Read that section for the reasoning — the failure
+modes, the ownership traps, and the three quiet ways an offsite credential can be
+wrong are the same. In short:
+
+```bash
+mkdir -p "${BACKUP_HOST_DIR:-./backups}/restic"
+sudo chown -R 1001:1001 "${BACKUP_HOST_DIR:-./backups}"
+just backup staging
+just restore-check staging
+
+just timers-install staging   # backup + watchdog + restore-check timers
+```
+
+Then fill in `/etc/relab/relab.env` with staging's own healthchecks.io URLs. Do not
+reuse prod's — a shared check cannot tell you which host went quiet. See
+[DEPLOY-PROD.md](DEPLOY-PROD.md) Part 1.2 for why the ping exists alongside Grafana.
+
+Set telemetry the same way as prod ([DEPLOY-PROD.md](DEPLOY-PROD.md) Part 1.5):
+`OTEL_EXPORTER_OTLP_ENDPOINT`, `OTLP_AUTH_TOKEN`, `TELEMETRY_EDGE_KEY` and
+`OTEL_EXPORTER_OTLP_PROTOCOL` in the root `.env`. Staging and prod may share the collector; they are
+separated by the `env` resource attribute, which Compose derives from `ENVIRONMENT`, so nothing
+needs configuring for that beyond using the right host's `.env`.
+
+That separation cuts both ways: staging needs **its own** `./bootstrap.sh relab staging`
+run on the monitoring host. Prod's rule matches `env="prod"` and will not notice staging
+going quiet. As on prod, run it in the same change that turns telemetry on — this host
+cannot tell you the rule is missing.
+
+Staging's offsite remote is named `surfdrive_staging` and its committed repository is
+`rclone:surfdrive_staging:` — a SURFdrive share link scoped to staging's own folder, so
+staging cannot reach prod's. The remote name is the only committed thing distinguishing
+the two, which is what makes a misplaced `rclone.conf` fail loudly.
+
+______________________________________________________________________
+
+## Part 2 — Routine release
+
+```bash
+cd /path/to/relab
+git fetch origin && git checkout main && git pull --ff-only
+
+just staging-build
+just staging-up YES scanning migrations
+```
+
+Add `scanning` only if `MALWARE_SCAN_ENABLED` is not `false` in the root `.env` —
+`staging-up` refuses to start on the mismatch. Staging is also the reasonable place to
+run *without* ClamAV if the host is short on RAM; it needs 3–4 GiB.
+
+Backups are not started by `up`; they run from `relab-backup@staging.timer`.
+
+### Verify
+
+```bash
+just watchdog staging
+just staging-logs
+```
+
+______________________________________________________________________
+
+## How staging differs from prod
+
+These are the reasons the two documents are not one:
+
+- **`just staging-migrate` seeds dummy data.** `prod-migrate` does not. Never point a
+  staging recipe at prod.
+- **No outage discipline.** Staging can be torn down and rebuilt at will; prod cannot.
+- **The data is disposable, the procedure is not.** What is being rehearsed here is the
+  sequence of commands, not the rows.
+- **Cloudflare is adopted for staging** (prod was not, as of 2026-08-19). Edge changes
+  go through `just cloudflare-plan staging` before apply, never as part of a deploy.
+- **Backups still matter.** Staging's repository and offsite copy exist and are
+  monitored. A backup path that only works in prod has not been rehearsed.
+
+## Rebuilding from scratch
+
+The one host where this is cheap, and the honest test of whether the deploy path works
+on a clean machine:
+
+```bash
+just staging-down YES scanning
+docker volume rm relab_staging_database_data   # destroys staging data — intended
+just staging-up YES scanning migrations
+```
+
+If that needs an undocumented manual step, prod will need it too — write it into
+[DEPLOY-PROD.md](DEPLOY-PROD.md) rather than remembering it.

+steps they describe (`backend/justfile`'s `backfill-upload-sizes` goes with them).

+Rehearse on staging before prod. The two hosts share `compose.deploy.yaml`, so a
+step that has only ever run on prod has never actually been tested.

+- `systemd/` — the three scheduled-job units (backup, watchdog, monthly restore
+  check). Render with `just timers-render`, install with `just timers-install <env>`;
+  the committed files carry placeholders, not any real host's paths.
+- `alloy/` — the Grafana Alloy agent config that ships container logs and host metrics
+  to the central collector. Loaded by `compose.telemetry.yml`, which the deploy
+  recipes include automatically when `OTEL_EXPORTER_OTLP_ENDPOINT` is set.
+- `env/` — committed, non-secret, per-environment Compose variables. Host-local
+  operator inputs live in the gitignored root `.env`; runtime secrets live in
+  `secrets/<env>/`.
+
+Four files are **vendored** from [CMLPlatform/monitoring](https://github.com/CMLPlatform/monitoring)
+and must stay byte-identical to it, because a fix upstream is meant to reach every
+project host unchanged. Everything project-specific arrives as an environment variable;
+if onboarding ever needs one of these edited, that is a bug to report upstream.

+
+```sh
+git -C ../monitoring checkout v0.2.0    # or the newer tag being adopted
+diff -u ../monitoring/templates/compose.telemetry.yml compose.telemetry.yml
+```
+
+Public self-hosting documentation is a different audience and lives in the docs
+subrepo (`docs/src/content/docs/operations/`). These four are for operating *this*
+deployment.

+// SHARED AGENT CONFIG — vendored from the central monitoring repo at a pinned tag.
+// Do not edit it per project: every deployment-specific value arrives as an environment
+// variable (PROJECT, ENVIRONMENT, COMPOSE_PROJECT_NAME, OTEL_EXPORTER_OTLP_ENDPOINT,
+// OTLP_AUTH_TOKEN, TELEMETRY_EDGE_KEY). If you find yourself editing this file to
+// onboard a project, that is a bug in the template — report it upstream instead, so the
+// next project does not hit the same wall.
+//
+// Ship this host's telemetry to the department OpenTelemetry collector: container
+// stdout/stderr as logs, and host resource metrics.
+//
+// An instrumented application sends its own traces and metrics over OTLP directly.
+// Everything else in the stack — databases, caches, proxies, frontends, batch jobs —
+// only writes to stdout, so this agent picks those up and forwards them on the
+// same OTLP endpoint with the same token. Nothing new is published at the edge: the
+// monitoring stack exposes `otlp.` and deliberately does not expose Loki, which has no
+// authentication of its own.
+
+// The host's own name, read from its /etc/hostname through the rootfs mount rather than

+# Design System: Relab Docs
+
+## Overview
+
+**Creative North Star: "Cyanotype & Manila — the colour of engineering documentation."** Same
+north star as `www/`, carried by inheritance rather than restated invention. See the [Named
+Rule](#named-rules) below on how that inheritance actually works.
+
+This is a **Starlight** site, and that fact governs almost everything about how its visual system is
+built. Starlight ships a complete, opinionated design system of its own (typography scale, color
+roles, sidebar chrome, code blocks, search UI) expressed as CSS custom properties (`--sl-color-*`,
+`--sl-text-h1/h2/h3`, `--sl-font-mono`, `--sl-content-width`, and dozens more).
+
+Relab's docs site does not re-author that system. It authors a **thin brand layer** (`brand.css`
+and `tokens.generated.css`, ~123 lines combined), loaded before Starlight's own styles in
+`customCss`. That layer then overrides a **deliberately short list** of Starlight's own tokens to
+pull the site onto brand. Everything else Starlight defines is **unmodified Starlight default**,
+not a Relab decision: spacing rhythm, sidebar layout mechanics, search modal, table styling, code
+block chrome (Expressive Code), badge/aside components, right-hand table-of-contents behavior.
+
+A reader auditing this file should read the frontmatter and the `### Relab-authored vs. Starlight-default` note under each section as the actual boundary. What's listed there was chosen;
+anything else in the rendered page is upstream Starlight, un-revisited.
+
+**On the duplicated brand rules below — the duplication is deliberate.** Several rules here
+(accent, eyebrows, elevation, radius, the typeface split) are restated in full from
+`assets/DESIGN.md` and also appear in `www/DESIGN.md` and `app/DESIGN.md`. That is not sloppiness
+and must not be "helpfully" deduplicated into a citation.
+
+The reason is mechanical. Whoever edits a component reads the design file next to it and does not
+open a second one, so a rule that lives only as a cross-reference is a rule nobody follows.
+`assets/DESIGN.md` is worse than inconvenient here: it sits at a path no design tooling looks in,
+which searches a subrepo root and the repo root only. A pointer to it is enforced by nothing.
+
+Each restatement therefore carries a `Mirrors assets/DESIGN.md:NN` marker.
+Run `rg "Mirrors assets/DESIGN.md"` to list every copy across the repo and check them against
+source in one command. `assets/DESIGN.md` remains the place to change a rule first.
+
+The four re-skin points that do the entire job are page background (`--sl-color-bg`,
+`--sl-color-bg-sidebar`, `--sl-color-bg-nav`) and the accent/interaction triad
+(`--sl-color-accent-low/DEFAULT/-high`, mapped to primary blue, **not** manila — see the Named
+Rule). The other two are the heading size ramp (`--sl-text-h1/h2/h3/h4`, pulled down from
+Starlight's stock landing-page-sized defaults to the brand's reference-document scale) and the
+mono font family (`--sl-font-mono`).
+
+**Three** Starlight component slots are swapped for custom `.astro` files, per `astro.config.mjs`:
+`SiteTitle` and `SocialIcons`, because their content (the wordmark, the "Open app" CTA) has no
+Starlight token to hook into. The third, `Head`, injects the font preload and favicon links.
+
+Two third-party renderers — mermaid and Scalar's API reference — live inside this system as
+embedded apps with their own theming surface. See [Elevation & Depth](#elevation--depth) and
+[Components](#components) for how (and how incompletely) each is wired to the brand.
+
+**Key Characteristics:**
+
+- A brand layer of custom properties sits *underneath* Starlight's own token layer; only a
+  short, named list of `--sl-*` tokens is overridden, everything else is Starlight's own design.
+- No Tailwind. `base.css` states this explicitly: Tailwind's preflight reset previously stripped
+  list bullets/indent from every markdown list, so docs styles with plain CSS and Starlight's
+  own `sl-*` utility classes only.
+- Reading measure is prioritized over Starlight's stock width: `--sl-content-width` is narrowed
+  from Starlight's default 54rem to 45rem, a measured 72 characters per line. Only wide mermaid
+  diagrams are allowed to break out of that column.
+- The categorical 7-hue diagram palette from `assets/DESIGN.md` is real and consistently used
+  across every architecture diagram, but it reaches mermaid as **literal duplicated hex per
+  diagram**, not as a live token reference. Mermaid's diagram-source language cannot consume
+  `var(--relab-chart-*)`, so the generated tokens exist as documentation-of-record for values
+  that are hand-copied into each `.mdx` file's `classDef` lines.
+
+## Colors
+
+The palette is identical to `www/`'s: cyanotype blue for structure and interaction, manila
+reserved for data labels. Docs consumes it as plain CSS custom properties (`--relab-brand-*`),
+generated into this repo by `scripts/sync_brand_assets.py` from `assets/tokens.json` /
+`assets/palette.json` — byte-identical to `www/src/styles/tokens.css`'s copy. **Do not hand-edit
+these values here**; change `assets/palette.json` (or `tokens.json` for the radius/shadow/chart
+values) and run `just assets-sync`.
+
+### Primary
+
+- **Cyanotype Blue** (`light-dark(#1f4c96, #8fb8ff)`, `--relab-brand-primary`): brand anchor.
+  Mapped onto Starlight's own `--sl-color-accent`, so it carries every link, active nav item,
+  and focus ring the framework renders — not just Relab-authored chrome.
+- **Cyanotype Blue, Strong** (`light-dark(#143567, #bad3ff)`, `--relab-brand-primary-strong`):
+  hover/pressed states; mapped to `--sl-color-accent-high`.
+- **Cyanotype Blue, Soft** (`light-dark(rgba(31,76,150,.08), rgba(143,184,255,.14))`,
+  `--relab-brand-primary-soft`): tinted fills — the active sidebar-link background and the
+  `.relab-card-grid` item background; mapped to `--sl-color-accent-low`.
+- **Active sidebar-link ink** (`rgb(18,49,75)` light / `rgb(234,247,255)` dark,
+  `components.css:60,71`): the one place in docs that hand-authors a colour rather than deriving
+  it. Deliberately tuned rather than drift: the nearest token, `--relab-brand-primary-strong`, is
+  close but does not match. The pair was picked for contrast against the tinted active-row
+  background above (measured 4.49:1 → 10.92:1 light, 8.57:1 dark). Recorded here with values so an
+  audit does not have to re-derive the intent; the detector flags both and the findings are
+  expected.
+
+### Secondary
+
+- **Manila** (`light-dark(#8f6212, #e3b95c)`, `--relab-brand-accent`): the data-label colour.
+  In docs' own custom CSS it appears in exactly one place — `.rung-num` in `NineRLadder.astro`,
+  labelling each R-strategy's number. It is intentionally **not** mapped to any Starlight
+  interaction token (see the Named Rule below).
+
+### Neutral
+
+- **Ink** (`light-dark(#16202e, #e9eff8)`, `--relab-brand-text`): body text color, set directly
+  on `body` in `base.css`.
+- **Page Ground** (`light-dark(#fafbfe, #11141d)`, `--relab-brand-background`): mapped to
+  `--sl-color-bg`, replacing a previous fixed-background photograph + blur treatment that taxed
+  reading contrast on every page load.
+- **Surface** (`light-dark(#f0f3fa, #1a2030)`, `--relab-brand-surface`): the card/panel tone,
+  matching the app's card and popover keys. New on web and not yet mapped to any Starlight token;
+  it used to be the (misnamed) page-ground value, so pair text contrast against Page Ground for
+  body copy and against Surface only inside cards.
+- **Divider** (`light-dark(#d9dfe8, #24314a)`, `--relab-brand-divider`): hairlines — the
+  colophon's top rule, `NineRLadder`'s tier and rung borders (via `--sl-color-hairline` with this
+  as fallback).
+- **Chrome Wash**: `--sl-color-bg-sidebar` / `--sl-color-bg-nav` are not a Relab token directly.
+  They're `color-mix(in srgb, var(--relab-brand-primary) 5%, var(--relab-brand-background))` — a
+  computed one-liner replacing Starlight's stock neutral grey (`#f6f7f9`/`#23262f`), which read
+  as a mismatched band once the page ground went flat.
+
+### Diagram & chart palette
+
+A 7-hue categorical ramp, each hue as a fill/stroke/text triplet, generated into
+`tokens.generated.css` (`--relab-chart-<hue>-fill/-stroke/-text`) and used across every mermaid
+diagram under `src/content/docs/architecture/*.mdx`. This is the same ramp defined in
+`assets/DESIGN.md`. Blue and manila are the brand primaries; verdigris and copper are borrowed
+from the alternative brand direction. Violet, rose, and slate fill out the seven roles diagrams
+need.
+
+| Hue             | Fill      | Stroke    | Text      |
+| --------------- | --------- | --------- | --------- |
+| Blue (primary)  | `#e3ecfa` | `#1f4c96` | `#143567` |
+| Manila          | `#f7ecd4` | `#8f6212` | `#5c3f0a` |
+| Verdigris       | `#e0f2ed` | `#0e6b5e` | `#0a4f45` |
+| Copper          | `#f9e7de` | `#a8542f` | `#6e371f` |
+| Violet          | `#ede6f7` | `#6d4fa3` | `#44337a` |
+| Rose            | `#fae4ec` | `#b0316e` | `#6e2048` |
+| Slate (neutral) | `#f1f4f8` | `#5a6675` | `#16202e` |
+
+Confirmed by direct inspection of `system-design.mdx`, `rpi-cam.mdx`, and `datamodel.mdx`: each
+assigns the hues by semantic category (`actor`=blue, `backend`=manila, `frontend`=verdigris,
+`external`=copper, `datastore`=violet, `hardware`=rose, `auth`/neutral nodes=slate). The mapping
+is applied via `classDef ... fill:#…,stroke:#…,color:#…` lines whose hex values are copy-pasted
+verbatim from this table. Mermaid's diagram-source grammar has no way to reference a CSS custom
+property. So the tokens in `tokens.generated.css` and the literals inside each `.mdx` are two
+copies of the same source of truth, kept in sync by hand rather than by the build.
+
+Separately, mermaid's own **chrome** (diagram background, node fill for un-classed nodes, line
+color) is themed by `src/scripts/mermaid.ts` through Mermaid's JS `themeVariables` API. It uses a
+small set of **hand-tuned hex values that are not derived from the chart ramp or from
+`brand.css`**. The file's own comment says so: *"hand-tuned surfaces; if brand.css primary
+changes, retune these (no machine link)."*
+
+This is a real, named drift risk. `mermaid.ts`'s `primaryBorderColor`/`primaryTextColor` do read
+live from `--relab-brand-primary`/`-text` (via `resolveLightDark`, because Mermaid's `khroma`
+color parser can't parse `light-dark()`). But the
+background/`primaryColor`/`lineColor`/`tertiaryColor` values are separately hand-picked hex with
+no update path if the brand primary ever moves.
+
+### Named Rules
+
+**The Accent-Is-Data Rule.** Manila (`--relab-brand-accent`) marks a *datum*, never a section or
+an interactive affordance. In docs it appears in exactly one custom-CSS location — the R-number
+in `NineRLadder.astro` — and nowhere else in `brand.css`/`base.css`/`components.css`. It is never
+mapped to `--sl-color-accent`; doing so would turn every Starlight link and active nav item
+manila, which `assets/DESIGN.md` explicitly forbids. `base.css` states this reasoning inline.
+The accent never fills a button and never drives a hover/pressed state; primary blue carries all
+interaction. Accent is for small text, never for mass — bars and big figures stay ink.
+*Mirrors assets/DESIGN.md:173 — change it there first.*
+
+**The No-Eyebrow Rule.** Docs carries no eyebrows/kickers, same as `www/`. A mono uppercase label
+that only restates the heading beneath it is chrome, not data; the app's `eyebrow` text variant
+is the one sanctioned exception, and it is app-only. No component in this subrepo uses an eyebrow
+pattern — confirmed by inspection of all four custom `.astro` components and `components.css`.
+The app's exception is the same principle, not a contradiction. There, an eyebrow labels a *value*
+inside a compact tag — the Accent-Is-Data Rule wearing different clothes, rather than announcing a
+section. *Mirrors assets/DESIGN.md:175 — change it there first.*
+
+## Typography
+
+**Display Font:** IBM Plex Serif 600 (with Georgia, serif fallback)
+**Body Font:** IBM Plex Sans 400–600 (with sans-serif fallback)
+**Label/Mono Font:** IBM Plex Mono 400 (with monospace fallback)
+
+**The Expo app deliberately diverges.** `app/` stays on platform system fonts — native feel,
+Dynamic Type support, zero load cost — and adopts only the *scale and palette*, not the typeface.
+This is intentional, not drift: do not "unify" the app onto IBM Plex.
+*Mirrors assets/DESIGN.md:33 — change it there first.*
+
+**Character:** A serif/sans/mono superfamily split by role rather than by hierarchy weight. The
+serif marks "this is a heading," the sans carries reading prose, and the mono marks "this is
+data" (R-numbers, tier labels, ladder-end captions, the colophon). All three ship as self-hosted
+WOFF2 latin subsets, preloaded for the sans weight range used above the fold.
+
+Docs does not set its own type scale. It maps the shared web scale from `assets/DESIGN.md` onto
+**Starlight's own heading tokens** (`--sl-text-h1/h2/h3/h4`), leaving Starlight's `--sl-text-*`
+tokens for everything else (body, small, code) untouched. Starlight's stock ramp rendered
+54px/35px/29px against a 16px body — roughly 1.45× the brand's own scale, which read as a landing
+page inside a reference site. So `base.css` overrides just the four heading steps:
+
+### Hierarchy
+
+- **H1** (600, 2.375rem / 38px, `--sl-text-h1`): page title. Matches the brand's "display 38"
+  step exactly.
+- **H2** (600, 1.5rem / 24px, `--sl-text-h2`): major section heading. Matches brand "h2 24".
+- **H3** (600, 1.1875rem / 19px, `--sl-text-h3`): subsection heading. Matches brand "heading 19".
+- **H4** (600, 1.0625rem / 17px, `--sl-text-h4`): the brand scale has no fourth heading step, so
+  this value is interpolated between H3 and Starlight's stock body size — not sourced from
+  `assets/DESIGN.md`.
+- **Body**: left as Starlight's own default (`--sl-text-base`, 16px) — a Relab-adopted value in
+  spirit (matches the brand's body step) but not an override; Starlight's stock value happened to
+  already match.
+
+All four heading selectors additionally get `font-family: IBM Plex Serif, Georgia, serif` and
+`letter-spacing: -0.01em` in `base.css`, applied to `h1, h2, h3, h4, .site-title, .hero` as a flat
+selector list. This is not routed through a `--sl-font-headings` token, because Starlight does not
+expose one for headings the way it does for body/mono.
+
+**Relab-authored vs. Starlight-default:** the four heading *sizes* and the heading *font-family*
+are Relab decisions (`base.css`). Body size, label size, code font size, and every other
+`--sl-text-*` step are unmodified Starlight defaults. `--sl-font-mono` is repointed to
+`--relab-brand-font-mono`. `--sl-font` (the body/UI font Starlight itself defines) is **not**
+overridden through Starlight's token — instead `base.css` sets `font-family` directly on
+`html, body`, which wins by source order/specificity but bypasses the token. As a result, a future
+Starlight component that reads `--sl-font` directly (rather than inheriting from `body`) would
+not pick up the brand sans.
+
+## Layout
+
+Single-column reading layout inherited from Starlight's docs template: fixed sidebar, header, and
+a centered content column. The one deliberate change is content width: `--sl-content-width` is
+set to `45rem`, narrower than Starlight's stock `54rem`, because continuous prose at Starlight's
+default measure sits well past comfortable reading width. **Measured in the browser: 720px at 16px
+IBM Plex Sans renders 72 characters per line**, squarely in the 45-75 range. An earlier draft of
+this file estimated ~86ch from the rem value alone and undersold the decision. That estimate was
+wrong because a rem-to-character conversion assumes an average glyph width this typeface does not
+have. Trust the measurement, not the arithmetic. Mermaid diagrams are the sole content type
+allowed to exceed this column: on viewports ≥72rem, `.relab-mermaid` breaks out to
+`calc(100% + 4.5rem)` with `-2.25rem` inline margins. Below that breakpoint the column is
+already full-width, so no break-out happens (avoiding induced horizontal scroll). The header grid
+gets one density tweak at ≥50rem (`grid-template-columns: minmax(max-content, auto) minmax(14rem, 1fr) auto`) to keep the widened `SiteTitle` wordmark, search box, and `SocialIcons`/CTA cluster
+proportioned. Everything else in the layout — sidebar width, TOC column, mobile nav collapse
+breakpoints, header height (`--sl-nav-height`) — is unmodified Starlight default.
+
+## Elevation & Depth
+
+**Flat, with no floating tier defined in docs' own CSS.** Unlike `www/` and the app, docs has no
+dialog, sheet, or menu of its own, so it never reaches for `--relab-radius-overlay` or
+`--relab-shadow-overlay`. `tokens.generated.css` still ships those values, since they're generated
+for the whole monorepo. But `base.css` says outright it "only uses the two tiers docs actually
+uses" (`--radius-control`, `--radius-card`): "it has no floating surface of its own, so no
+overlay."
+
+The monorepo rule this inherits: inline surfaces (cards, rows, inputs) are flat — a 1px hairline
+border plus a surface fill, no shadow. Shadow is reserved for one tier, `shadow-overlay`, on
+surfaces that genuinely float. Docs simply never reaches that tier.
+*Mirrors assets/DESIGN.md:123 — change it there first.*
+
+Depth in the rendered page comes entirely from Starlight's own component chrome (search modal,
+mobile nav drawer), which docs does not restyle. The one visual "frame" docs authors itself —
+`.relab-mermaid` — is a bordered, tinted panel, not a shadowed one: 1px `color-mix()` border,
+tinted background, `border-radius: var(--radius-card)`, no box-shadow.
+
+## Shapes
+
+The full scale is control 6px, card 8px, overlay 12px, full 9999 (avatars and true pills only).
+*Mirrors assets/DESIGN.md:113 — change it there first.*
+
+Same flat-&-sharp scale as the rest of the monorepo, but docs only draws from the bottom two rungs —
+it has no overlay-tier surface. `--radius-control` (6px) sizes the site-title logo image and the
+sidebar active-link box-shadow inset; `--radius-card` (8px) sizes `.relab-card-grid` items and the
+`.relab-mermaid` frame. Borders throughout are 1px hairlines in `--relab-brand-divider` or a
+`color-mix()` tint of primary — never a heavier rule weight. `NineRLadder`'s staircase geometry (see
+[Components](#components)) is the one place docs draws a genuinely custom shape: each rung's
+`border-left` + `border-bottom` pair chains into a continuous descending flight, with no extra
+structural elements.
+
+## Components
+
+### Navigation (Starlight-inherited, lightly re-skinned)
+
+Sidebar link styling, mobile collapse, and the search trigger are unmodified Starlight
+components. The one custom override is the **active-page state**
+(`.sidebar-pane a[aria-current="page"]`, `components.css`): a `color-mix()`-tinted primary
+background (14% light / 22% dark) with a matching inset box-shadow ring and bold text. This
+replaces whatever Starlight's stock active-link treatment would otherwise render. Header layout
+comes from two swapped component slots (not token overrides):
+
+- **`SiteTitle`** (`src/components/SiteTitle.astro`): the R9lab wordmark, theme-swapped via two
+  `<img>` elements toggled by Starlight's `dark:sl-hidden`/`light:sl-hidden` utility classes
+  (there is no CSS-only single-asset swap for an `<img src>`). It also adds a "Docs" text cue,
+  separated by a 1px vertical rule in `--sl-color-gray-5`. The rule's text color was tuned from
+  `gray-3` (4.49:1 in dark mode, just under WCAG AA) to `gray-2` (10.92:1 light / 8.57:1 dark).
+- **`SocialIcons`** (`src/components/SocialIcons.astro`): repurposed to render the GitHub icon
+  plus a promoted **primary CTA button** ("Open app") for the `external`-typed social link. It's
+  filled `--relab-brand-primary`, with `--radius-control` corners and
+  `--relab-brand-primary-strong` on hover, and drops below 30rem viewport width to keep the
+  collapsed header uncluttered.
+
+### Cards (Relab-authored)
+
+`.relab-card-grid` (`components.css`): an auto-fit CSS grid (`minmax(15rem, 1fr)`) of plain `<li>`
+cards used for the landing-page section links. **Shape:** `--radius-card` (8px). **Background:**
+`color-mix(in srgb, var(--relab-brand-primary) 4%, transparent)` — a near-imperceptible primary
+tint, not the flat `--relab-brand-surface` token. **Border:** 1px, `color-mix()` primary at 18%.
+No hover state is defined in CSS — cards are plain links, not interactive surfaces with their own
+affordance.
+
+### Colophon (Relab-authored, signature pattern)
+
+`.relab-colophon` (`components.css`, content generated by `Colophon.generated.astro`) sets
+research metadata (affiliation, authors, citation DOI, license, funding, contact) in mono at
+13px/1.6, with one hairline rule above and deliberately **no cards and no icons**. The
+component's own comment frames it as replacing a shields.io badge row that loaded four
+third-party images and read as README furniture rather than reader-facing content.
+
+### NineRLadder (signature custom component)
+
+`src/components/NineRLadder.astro` — the 9R framework drawn as a literal descending staircase,
+one figure per page (`architecture` docs), not a reusable widget. Ten rungs across three grouped
+tiers (make/extend-life/materials-only), each `<li class="rung">` indented by
+`calc(var(--step) * var(--stair))` where `--step` is the strategy's own rank (0–9). The indent
+alone draws the staircase, no chart library. Deliberately **no bar or width encoding "value
+retained"**: the component's own comment states the 9R order is ordinal. A bar would invent a
+magnitude the source taxonomy (Potting et al. 2017) never measured. Rung numbers (`R0`…`R9`) are
+set in mono and colored with the **manila accent** — the ladder's one and only accent use in the
+entire component, consistent with the Accent-Is-Data Rule. Responsive: the stair unit itself
+shrinks from `1.15rem` to `0.5rem` under 50rem rather than switching to a different layout.
+
+### Mermaid diagrams (third-party, partially themed — drift risk)
+
+Rendered client-side via `mermaid` + `@mermaid-js/layout-elk`, orchestrated by
+`src/scripts/mermaid.ts`. **Chrome** (background, un-classed node fill, line color) is themed via
+Mermaid's `themeVariables`, partly live (`primaryBorderColor`/`primaryTextColor` resolve
+`light-dark()` brand tokens at runtime). The rest is partly hand-tuned hex with **no update
+path** if the brand primary changes (see Colors § Diagram & chart palette). **Content** (the
+actual node/edge
+categorical colors) is themed via literal hex `classDef` lines duplicated by hand from the chart
+ramp, not through this component at all. That theming lives in the `.mdx` content files.
+The wrapping frame (`.relab-mermaid`: border, radius, background tint, horizontal scroll for
+overflow) is fully Relab-authored in `components.css`.
+
+### API reference pages (third-party, **not themed**)
+
+`src/pages/api/*` use `@scalar/api-reference`, rendered through `api-reference-page.astro` +
+`src/scripts/api-reference.ts`. Scalar ships its own `style.css`, imported unmodified. **No
+Relab CSS variable, theme override, or custom Scalar theme option is passed at all.** The
+`api-reference` config object only sets functional options (`baseServerURL`, `hideClientButton`,
+`persistAuth: false`, `telemetry: false`), none of them visual. The interactive reference surface
+therefore renders in Scalar's own vendor default theme, visually disconnected from the rest of
+docs. The only Relab-authored chrome on these pages is the wrapping shell
+(`api-reference-page.astro`'s own `<style>` block). It is the sticky switcher nav between
+Public/Device/RPi-camera API references, built from the same brand primitives
+(`--relab-brand-primary`, `--radius-control`) as the rest of the site. It also sets the
+`<meta name="theme-color">` tag, whose value is parsed at build time out of `brand.css`'s raw
+text via a regex match on `--relab-brand-theme-color`, rather than read as a token.
+
+## Do's and Don'ts
+
+### Do
+
+- **Do** treat `tokens.generated.css` as read-only. It's generated from `assets/tokens.json` by
+  `scripts/sync_brand_assets.py` and is byte-identical to `www/`'s copy; edit the source JSON and
+  run `just assets-sync`.
+- **Do** map new Starlight interaction states (if any get overridden) onto the primary blue
+  family, never manila — Starlight's `accent` token is its *interaction* color, not Relab's
+  *data-label* accent, and the two must not collide.
+- **Do** keep the manila accent scarce and small when it does appear (the R-number in
+  `NineRLadder`, per the app-wide "accent is for small text, never for mass" rule) — nothing in
+  docs currently uses it any other way.
+- **Do** reuse the categorical chart ramp's fixed hue-to-category mapping (actor=blue,
+  backend=manila, frontend=verdigris, external=copper, datastore=violet, hardware=rose,
+  neutral=slate) when adding a new architecture diagram, and copy the literal hex from the table
+  above rather than inventing new values. The mapping's consistency across diagrams is the point.
+- **Do** let mermaid diagrams break out of the prose column on wide viewports rather than
+  widening the whole column to fit them; keep the reading measure narrow for prose.
+
+### Don't
+
+- **Don't** add eyebrows/kickers to any docs heading or section — the No-Eyebrow Rule applies to
+  both `www/` and `docs/`; it is app-only.
+- **Don't** point `--sl-color-accent` at `--relab-brand-accent` (manila) — it was deliberately
+  left pointed at primary blue specifically to avoid this.
+- **Don't** assume the mermaid diagram content colors are live-bound to `tokens.generated.css` —
+  they are hand-copied literals in each `.mdx` file; changing the generated token alone will not
+  update rendered diagrams.
+- **Don't** assume the Scalar API reference pages inherit brand theming — they currently render
+  in Scalar's unmodified vendor default theme; only the wrapping shell nav is on-brand.
+- **Don't** reach for Tailwind utility classes in docs — the subrepo deliberately ships none;
+  Tailwind's preflight reset previously broke markdown list rendering here.
+- **Don't** add a floating/shadowed surface to docs without also adding `--radius-overlay` and
+  `--shadow-overlay` usage deliberately. Docs currently has no floating tier at all, and
+  introducing one silently (e.g. a shadow with no radius-scale backing) would break the
+  flat/one-floating-tier discipline the rest of the monorepo holds.

+title: API reference
+description: Choose an interactive Relab API reference generated from the committed OpenAPI schemas.
+---
+
+The Relab API references are interactive views of the generated OpenAPI schemas committed with the
+docs site. Use them for endpoint details, request and response models, authentication requirements,
+and schema downloads.
+
+Three references are published, one per audience:
+
+- [Public API](/api/public/) is the application API, covering platform data, accounts,
+  authentication, media, and public research records. This is the one to use unless you are building
+  a device integration.
+- [Device API](/api/device/) is the backend-facing integration API for pairing devices and Relab
+  plugins with the platform.
+- [RPi camera API](/api/rpi-cam/) is the local camera service API, for status checks, capture
+  workflows, and camera-device integration.
+
+## Licensing
+
+The public and device schemas, and the client types generated from them, are published under
+Apache-2.0 rather than the platform's AGPL. Generating a client from either one carries no copyleft
+obligation into your own code, and Apache-2.0 adds a patent grant. The RPi camera schema comes from
+a separate repository and is not covered by that carve-out. See [Licensing](/project/licensing/) for
+the reasoning and for the terms covering the platform itself and its dataset releases.
+
+For practical scripting guidance, start with the [API interaction guide](../user-guides/api/). For
+implementation architecture, see [API structure](../architecture/api/).

+Routes are organized by domain, not by HTTP verb. The same API serves the research app, the public web frontend, and external tooling. Public and authenticated surfaces are separated in practice, but the cleanest source of truth is the live OpenAPI docs.
 
-The RELab backend exposes a REST-style API used by the Expo app, the public web frontend, and selected operational tooling. Public and authenticated surfaces are separated in practice, but the cleanest source of truth is the live OpenAPI docs.
+For live schemas and request models, start from the [API reference overview](/api-reference/). For practical usage guidance, see the [API interaction guide](../../user-guides/api/).
 
-For the live schema and request models, use the [interactive API documentation](https://api.cml-relab.org/docs). For practical usage guidance, see the [API Interaction Guide](../../user-guides/api/).
+There are three distinct surfaces: the public app API is the contract for the
+frontend and external clients, the device API handles Pi-originated HTTP
+callbacks, and a small private DTO seam covers backend device integration plus
+the RPi camera plugin.
 
-## Route Organisation
+## Route organization
 
-### Authentication & User Management
+### Authentication and user management
 
-- `/auth/*` — login, logout, refresh, registration, verification, password reset, and OAuth
-- `/users/*` and `/organizations/*` — authenticated user and organization operations
-- `/admin/users/*` and `/admin/organizations/*` — superuser administration
+- `/v1/auth/*` — login, logout, refresh, registration, verification, password reset, and TOTP MFA setup/challenge flows
+- `/v1/oauth/*` — Google, GitHub, and YouTube account authorization, callbacks, token exchange, and account linking
+- `/v1/users/*` — authenticated user self-management
+- `/v1/profiles/{username}` — username-addressed public profile reads
+- `/v1/admin/users/*` — superuser user administration
 
-### Data Collection
+### Data collection
 
-- `/products/*` — product creation, reads, updates, search, and parent-child component relations
-- `/users/me/products/*` and `/users/{user_id}/products/*` — user-scoped product access
+- `/v1/products/*` — base-product creation, reads, updates, search, owner filters, base-product media, videos, bill-of-materials, and parent-scoped component lists
+- `/v1/products/facets` and `/v1/products/suggestions/*` — filter facets and brand/model autocomplete suggestions for product search
+- `/v1/components/*` — stable component reads, updates, component-scoped media, and component bill-of-materials
+- `/v1/products?owner=me` and `/v1/users/{user_id}/products/*` — user-scoped product access
 
-### Reference Data
+### Reference data
 
-- public `/taxonomies`, `/categories`, `/materials`, `/product-types`, and `/units` endpoints for reference lookups
-- `/admin/*` variants for controlled management of background data
+- public `/v1/taxonomies`, `/v1/categories`, `/v1/materials`, `/v1/product-types`, and `/v1/units` endpoints for reference lookups
+- `/v1/admin/*` variants for controlled management of reference data
+
+### Statistics
+
+- `/v1/stats/totals`, `/v1/stats/series`, and `/v1/stats/categories` — aggregate public totals, time series, and category breakdowns for dashboards and reporting
 
 ### Media
 
-- `/images/*` and related file-storage endpoints for uploads, linked media, and retrieval
+- image/file payloads expose generated `/uploads/*` media URLs, including precomputed thumbnails when available
+- base-product media remains under `/v1/products/{id}/images` and `/v1/products/{id}/files`
+- component media uses `/v1/components/{id}/images` and `/v1/components/{id}/files`
+- hyperspectral datasets use file routes, not image routes, so raw ENVI, HDF5, NITF, and GeoTIFF data is stored without image rewriting
+- videos are base-product-only under `/v1/products/{id}/videos`
+
+## Product and component resources
+
+Base products and components share the same database table, but they are separate API resources:
+
+- base products are addressed through `/v1/products/{id}`
+- components are addressed through `/v1/components/{id}`
+- new components are created in parent context: use `POST /v1/products/{id}/components` for a base-product parent and `POST /v1/components/{id}/components` for a component parent
+- direct children and bounded base-product subtrees are listed with `/v1/products/{id}/components` and `/v1/products/{id}/components/tree`
+- bill-of-materials routes follow the addressed resource: `/v1/products/{id}/materials` for base products and `/v1/components/{id}/materials` for components
+
+Product and component entry is progressive. A record can be created before its full component tree or bill of materials is known; completeness checks belong to later curation and audit workflows, not to create-time validation.
+
+Product- and component-create requests (`POST /v1/products`, `POST /v1/products/{id}/components`, `POST /v1/components/{id}/components`) accept an optional `Idempotency-Key` header so a client can safely retry a request whose response was lost after the server had already committed it. The first request with a given key is processed normally; a retry with the same key returns the original response instead of creating a duplicate record.
+
+A key is only replayed when everything about the retry matches the original:
+
+- the same authenticated user, so a key cannot be replayed across accounts
+- the same target, including the parent id: the same key on `POST /v1/products/1/components` and `POST /v1/products/2/components` are two separate requests
+- the same request body — reusing a key with a different payload returns `422`, rather than silently returning the earlier record
+
+A retry that arrives while the first request is still running returns `409`. If the idempotency store is unreachable the request fails closed with `503` instead of risking a duplicate create. Stored responses expire after one hour.
+
+Owner attribution is viewer-aware. Public profiles show product owner names to everyone, community profiles show them only to signed-in users, and private profiles show them only to the owner and admins. Hidden owner identity is returned as `null` rather than exposing a username or owner id.

+
+Routes live in `app/src/app/` as an Expo Router file tree. Segments in parentheses are groups:

+is served at `/products`.
+

+    Tabs --> Account
+```
+
+| Route | What it is |
+| ----- | ---------- |
+| `/` | Entry redirect. Renders nothing and sends you to `/products`. |
+| `/login` | Password and OAuth sign-in. Accepts a `redirectTo` parameter. |
+| `/new-account` | Password registration. |
+| `/forgot-password`, `/reset-password` | Password reset request and completion. |
+| `/mfa` | Second factor, reached only from a sign-in that needs one. |
+| `/verify` | Email verification landing page, opened from a link. |
+| `/onboarding` | Username choice, for accounts created without one. |
+| `/products` | Product list. The app's home. |
+| `/products/new` | Capture screen for a new top-level product. |
+| `/products/[id]` | Product detail, also the edit surface. |
+| `/products/[id]/components/new` | Capture screen for a component of that product. |
+| `/components/[id]` | Component detail. Same screen family as a product. |
+| `/components/[id]/components/new` | Capture screen for a nested component. |
+| `/cameras` | Paired camera list. |
+| `/cameras/add` | Pairing a new Raspberry Pi camera. |
+| `/cameras/[id]` | Camera detail, live view and streaming controls. |
+| `/account` | The signed-in account: profile, preferences, integrations, sign-out. |
+| `/category-selection` | Category and product-type picker. Presents over whichever screen opened it. |
+| `/users/[username]` | Public contributor profile. |
+
+Three things about that tree are load-bearing:
+
+- **Each tab is a group holding its own Stack.** A tab keeps its navigation trail while you are
+  on another one, which is why `(products)`, `(cameras)` and `(account)` are groups rather than
+  plain screens.
+- **The products tab owns both `/products` and `/components`.** A component is a product's
+  child, so cards, breadcrumbs and post-create redirects hop between the two trees. Splitting
+  them across navigators would make every hop a cross-navigator replace.
+- **`/category-selection` and `/users/[username]` sit on the root stack, not in a tab.** More
+  than one tab reaches them, so they should not join any single tab's trail.
+
+Accounts with the Raspberry Pi integration switched off do not see the cameras destination. The
+tab still exists; `useVisibleDestinations` in `src/navigation/destinations.ts` filters the
+navigation chrome.
+
+## Getting in
+
+The app gates nothing behind a splash or a login wall. `/` redirects to `/products`, and the
+product list renders for signed-out visitors. Each action asks for an account only when it
+needs one.
+
+```mermaid
+---
+config:
+    layout: elk
+---
+graph LR
+    accTitle: Sign-in and session gating
+    accDescr: An action needing an account sends you from the product list to the login screen, carrying a redirectTo parameter. Sign-in passes through the MFA screen when a second factor is enabled, then through onboarding when the account has no username, and lands on the redirect target, or the product list when there is none.
+
+    Products["/products"] --> Login["/login"]
+    Login --> Mfa{"MFA?"}
+    Mfa -->|Yes| MfaScreen["/mfa"]
+    Mfa -->|No| Username
+    MfaScreen --> Username{"Username?"}
+    Username -->|No| Onboarding["/onboarding"]
+    Onboarding --> Target
+    Username -->|Yes| Target["redirectTo<br/>or /products"]
+```
+
+**The auth gate** is `useRequireAuth(redirectTo)`. It replaces the current route with `/login`
+and carries the caller's own path as `redirectTo`, so the person lands back where they were
+going.
+
+It holds that redirect back in three cases:
+
+- while the session is still restoring, so a slow restore cannot flash a signed-in user to the
+  login screen;
+- on any screen that is not focused, because tab groups keep screens mounted off-focus and a
+  stale redirect would fire after that screen had already navigated elsewhere;
+- during sign-out.
+
+**`redirectTo` is validated, not trusted.** `getSafeRedirectTarget` accepts only a path
+beginning with a single `/`, and re-resolves it to confirm it cannot escape the app's origin.
+Anything else — an absolute URL, a protocol-relative `//host` — is dropped and the sign-in falls
+back to `/products`. Treat that function as the boundary: a new caller passing a
+`redirectTo` from anywhere external must go through it.
+
+**Two separate checks enforce onboarding, deliberately.** `routeAuthenticatedUser` sends a
+fresh sign-in to `/onboarding` when the account has no username. A root-level effect in
+`_layout.tsx` then re-checks on every path change, because an account can reach a signed-in
+state without passing the sign-in screen at all: an OAuth callback, or a restored session. An
+account needs a username before it can own records. That same effect bounces you off
+`/onboarding` once a username exists, so nobody can revisit the screen.
+
+## Recording a product
+
+Record creation is capture-first: photograph and name the product, save it straight away, then
+fill in the detail on the record that now exists. An interrupted lab session therefore loses at
+most the photographs and the name, never a part-filled form.
+
+```mermaid
+---
+config:
+    layout: elk
+---
+graph LR
+    accTitle: Capture-first record creation
+    accDescr: The new product route renders the capture screen, which takes photos, a name and a type. Saving posts the record immediately, then replaces the route with the detail screen in edit mode. Adding a component repeats the same path from the detail screen.
+
+    New["/products/new"] --> Capture["Capture screen:<br/>photos, name, type"]
+    Capture --> Picker["/category-selection"]
+    Picker --> Capture
+    Capture --> Save["POST the record"]
+    Save --> Detail["/products/[id]<br/>edit mode"]
+    Detail --> Component["components/new"]
+    Component --> Capture
+```
+
+The move into the detail screen is a `replace`, not a `push`. The capture screen has served its
+purpose, and leaving it in the back stack would make "back" from a saved record return to a
+form for creating that record again. Leaving the capture screen with unsaved input prompts
+first; the flag that permits a discard also permits the post-save replace.
+
+Adding a component runs the identical path one level down, from `/products/[id]` or
+`/components/[id]`. Nesting is not capped, but the breadcrumb trail is: `useAncestorTrail` walks
+at most 12 ancestors before it stops, so a deeper record shows a truncated trail rather than a
+complete one.
+
+## Rules a routing change has to keep
+
+**Crossing tabs uses `navigate`, never `replace`.** React Navigation resolves a replace that
+targets another navigator by swapping the whole tab navigator out, which resets every tab's
+trail. Within one tab's stack, `replace` is fine and is what the capture flow uses.
+
+**The category picker returns; it does not redirect.** The capture screen and a detail screen's
+type field both push it, and both expect it to come back with a selection. It sits on the root
+stack so that either caller can reach it without joining that caller's tab trail.
+
+**Public profiles come back to `/products`.** `/users/[username]` sits outside the tabs, so its
+header back button navigates to `/products` rather than popping. A shared link can open the
+route with nothing to pop back to.
+
+**Detail screens are anchored-scroll documents.** Sections self-register and the chips (phone)
+or outline (large web) scroll to them. They are not sub-routes, so adding a section does not add
+a route.

-Bearer tokens for API clients, cookies for browser sessions. Both are supported, and Redis is part of the production auth path.
-</div>
+Relab supports bearer tokens for API clients and httpOnly cookies for browser sessions. Redis backs auth token storage, MFA challenge state, and rate limiting.

+Authentication is built on [FastAPI-Users](https://fastapi-users.github.io/fastapi-users/latest/) with Relab-specific refresh-token, session-cookie, OAuth, and validation logic.

-- `cookie` for browser-based sessions that rely on the `auth` cookie
+The API exposes two login transports:
 
-In development and tests, the access-token strategy can fall back to signed JWTs if Redis is unavailable. Outside development, Redis is expected to be present. Access tokens are short-lived and refresh tokens are handled separately.
+- bearer tokens for native apps, scripts, and API clients
+- session cookies for browser-based clients
 
-## Supported Flows
+## Supported flows
 
-- Email/password login
-- Cookie-based login for web sessions
-- Bearer-token login for programmatic clients
-- Refresh-token rotation
-- Logout and token revocation
-- Password reset
-- Email verification
-- OAuth login and account linking for Google and GitHub
-- Client-side PKCE OAuth for Google on web (no backend redirect required)
-- Disposable email validation during registration
+- Email/password login with optional TOTP MFA completion for accounts that enable it
+- Refresh-token rotation and logout revocation
+- Password reset and email verification
+- Google and GitHub OAuth login with the same optional TOTP MFA completion step
+- OAuth account linking for existing users
+- Disposable email checks during registration
+
+## Security controls
+
+Password validation follows the project baseline from the [OWASP Authentication Cheat Sheet](https://cheatsheetseries.owasp.org/cheatsheets/Authentication_Cheat_Sheet.html). Passwords must be 12 to 128 characters, must not contain the username or email address, and are checked against a committed ASVS-sized common-password fallback that is seeded into Redis when available. New and reset passwords are also checked with Have I Been Pwned using the k-anonymity range API. Stored passwords use the backend-owned Argon2id profile; Relab does not store reversible passwords.
+
+The breach check fails open if Have I Been Pwned is unavailable. The frontend keeps standard password inputs and does not block paste, so password managers work normally.
+
+Changing `email` or `password` through `PATCH /v1/users/me` requires `current_password`. Username, profile, and preference updates do not. Email changes mark the account unverified, send a verification email to the new address, and send a security notification to the previous address. Password changes send a security notification to the account email address.
+
+TOTP MFA is optional account hardening:
+
+- Accounts without TOTP receive bearer tokens or session cookies after a successful password or OAuth login.
+- Accounts with TOTP receive a short-lived challenge token and must submit a current one-time code before the API issues credentials.
+- Sensitive backend routes can require confirmed MFA via the MFA dependency.
+- TOTP seeds and pending challenge tokens are generated with cryptographically secure randomness.
+- Accepted TOTP counters are recorded briefly to prevent replay within the allowed clock window.
+- Administrators can reset a user's MFA enrollment after identity-proofed recovery, but cannot choose a replacement factor.
+
+Forgot-password responses do not reveal whether an account exists. The API returns the same accepted response for known, unknown, and inactive accounts and pads the response to a small minimum duration to reduce timing-based account enumeration. Login failures use the same bad-credentials response for unknown, invalid, and inactive accounts.
+
+Rate limits use the existing Redis-backed `limits` integration:
+
+- login by transient client-IP bucket and by a keyed digest of the submitted identifier
+- forgot-password requests by transient client-IP bucket and by a keyed digest of the submitted email address
+- reset-password submissions, registration, and email verification requests by transient client-IP bucket
+
+Password reset uses side-channel email links. Reset tokens are valid for one hour and are invalidated after a successful password change because they include a fingerprint of the previous password hash. A successful reset revokes existing refresh tokens and sends a confirmation email without credentials, reset tokens, or reset links. The web app is served with `Referrer-Policy: no-referrer`; the app also removes the token from browser history after loading the reset page.
+
+Auth logs record successful logins and rate-limit events. They do not include plaintext passwords, reset tokens, verification tokens, refresh tokens, full verification/reset URLs, or full email addresses.
+
+## Token handling
 
 ```mermaid
 sequenceDiagram
+    accTitle: Login and token issuance flow
+    accDescr: A user submits bearer or session login credentials to the API, which validates them against the database, updates last-login metadata, creates access and refresh tokens in Redis, and returns bearer JSON tokens or browser cookies.

-    end
+    API->>TokenStore: Create access and refresh tokens
+    API-->>User: Bearer JSON tokens or browser cookies
 ```
 
-## Session Handling
+Access tokens are short-lived: the application access-token lifetime is 15 minutes. Auth flows require Redis and fail closed when Redis-backed token state is unavailable.
+
+Successful login updates `last_login_at` without storing full login IP addresses on user accounts. Client IP addresses may still be processed transiently for Redis-backed rate limiting. Login also creates a refresh token. Browser sessions receive refresh and access cookies; bearer clients receive tokens in the response body.
+
+Refresh-token rotation uses dedicated endpoints:
+
+- `POST /v1/auth/bearer/refresh` for bearer clients
+- `POST /v1/auth/session/refresh` for browser sessions
 
-Login also:
+Refresh tokens have a 30-day inactivity lifetime and a 30-day absolute session lifetime. Each successful refresh rotates the refresh token, but rotation preserves the original absolute expiry, so activity cannot extend a session beyond 30 days. Relab allows multiple concurrent sessions per account within that lifetime. Users can end all of them from the profile screen with "Sign out everywhere"; a per-device session inventory is not provided.
 
-- updates `last_login_at` and `last_login_ip`
-- creates a refresh token when Redis is available
-- sets the `refresh_token` cookie for browser sessions
+Token revocation events:
 
-Refresh-token rotation happens through dedicated endpoints:
+- **Bearer logout:** revokes the submitted refresh token.
+- **Session logout:** clears auth cookies, asks the browser to clear local session data, and blacklists the refresh token when one is present.
+- **Revoke all** (`POST /v1/auth/sessions/revoke-all`): revokes every refresh *and* access token for the account and clears browser session state.
+- **Password reset, password change, email change, account deactivation, and account deletion:** all revoke every refresh and access token for the affected account.
 
-- `POST /auth/refresh` for bearer-style clients
-- `POST /auth/cookie/refresh` for browser sessions
+Access tokens carry their issue time, and each revocation records a per-user epoch in Redis; a token issued before that epoch is refused on its next request. Revocation is therefore immediate rather than bounded by the 15-minute token lifetime, and costs one write regardless of how many sessions the account has. Refresh state is always purged before the epoch is stamped, so a refresh racing the revocation cannot mint a token that outlives it.
 
-Logout clears the access cookie, deletes the refresh cookie, and blacklists the refresh token when present.
+Refresh tokens are random bearer secrets. Redis stores them under SHA-256 fingerprints rather than raw token values, so storage keys are not usable credentials if exposed. OAuth provider tokens that must remain reversible, such as Google/YouTube access and refresh tokens, are encrypted before database storage with AES-256-GCM using the backend `DATA_ENCRYPTION_KEY`.
+
+Encryption does not replace authorization: authenticated API handlers check resource ownership and route-level permissions before returning or mutating data.
+
+Authorization is enforced in the backend route layer, not by client-side UI state. FastAPI dependencies separate public reads, authenticated self-service, verified-user writes, owner-scoped resources, device assertions, and superuser-only admin routes. Client request bodies cannot set account-control or ownership fields, and product owner identity is redacted from viewers who cannot see the owner's profile.
 
 ## OAuth
 
-OAuth login is available for Google and GitHub. Each provider supports:
+OAuth login is available for Google and GitHub. Both providers support session-cookie callbacks, bearer-token callbacks, and account linking. Google accounts may be linked by verified email. GitHub linking requires explicit association. OAuth login creates Relab-owned access and refresh sessions; Relab does not claim IdP-wide logout or coordinated provider session termination.
+
+### Backend-mediated flow
+
+Google and GitHub use the backend-mediated flow on all platforms.
 
-- a token-based callback flow
-- a cookie-based callback flow
-- account linking for existing users
+Callbacks use a CSRF cookie and signed state token. Frontend redirect targets must exactly match the backend allowlist derived from `APP_PUBLIC_URL` (`/login` and `/account`) plus the fixed native app redirects (`relab-app://login` and `relab-app://account`). Entries are normalized as `scheme://host/path` and must not contain credentials, query strings, or fragments. Provider callback URLs are versioned under `/v1/oauth` and must be registered with each provider:
 
-Google accounts may be auto-linked by email because Google verifies ownership. GitHub linking is stricter and requires explicit association.

+- `https://api.cml-relab.org/v1/oauth/github/session/callback`
+- `https://api.cml-relab.org/v1/oauth/github/associate/callback`
 
-### Backend-mediated flow (GitHub all platforms, Google on native)
+The public backend origin comes from `API_PUBLIC_URL`; production uses `https://api.cml-relab.org`. Bearer callback routes use the same pattern, such as `/v1/oauth/google/token/callback`, when enabled for a client.
 
-OAuth callbacks use a CSRF cookie and a signed state token. Redirect targets are restricted by allowlists in the auth settings.
+Frontend OAuth callback results are carried only in the URL fragment: `#status=success`, `#status=error&error=<code>`, or `#status=mfa_required&mfa_handoff=<one-time-handoff>`. The app handles the fragment, clears it from browser history, and never receives Relab access tokens through callback URLs. When OAuth login needs MFA, the app claims the one-time handoff through the API, stores the returned pending MFA challenge in app runtime/session storage, and routes immediately to the MFA screen. The MFA challenge token itself is never placed in query strings or URL fragments.

-### Client-side PKCE flow (Google on web)
-
-The web frontend uses `expo-auth-session` to run a PKCE flow directly with Google, then exchanges the resulting ID token for a session via a dedicated backend endpoint. No backend redirect is involved, so there is no dependency on any third-party auth proxy.

+Someone drew the diagram above by hand, and it simplifies on purpose. `backend/scripts/generate/export_datamodel.py` generates the per-context diagrams below from the ORM metadata, so they list every column and every foreign key the database really has. `just check` fails when they fall behind the models.
 
 ## User management
 
-This part covers user accounts, organisations and membership, linked OAuth accounts, and ownership and access control. It is kept separate from the research entities so auth concerns do not leak into the product model more than necessary.

-## Background data
+`hashed_password` and `mfa_totp_secret` appear in no read schema, so no response ever carries them, and the TOTP secret is encrypted at rest on top of that. `profile_stats` is a cached aggregate that `profile_stats_computed_at` stamps, rather than a figure recomputed per request. `upload_file_count` and `upload_total_bytes` hold the per-account upload quota ledger.

+## Reference data
 
 This part contains the shared reference layer used to keep records more consistent: taxonomies, categories and subcategories, materials, product types, and units.
 
 These records are shared across users and products. They are not the research record itself, but they make the research record easier to search, compare, and reuse.

+
+`materialproductlink` records how much of a material sits in a product. It belongs to data collection rather than here, because it carries a measurement rather than a classification, so it appears in the next diagram.
 
 ## Data collection
 
-The data collection model is centred on `Product`, which is used both for top-level products and nested components. That makes it possible to represent a disassembly tree without separate tables for products and parts.
+The data collection model is centered on `Product`, which is used both for top-level products and nested components. That makes it possible to represent a disassembly tree without separate tables for products and parts.
 
 Important characteristics:
 
 - a product can have a parent product, enabling component hierarchies
-- physical and circularity-related properties are stored separately from the core product record
+- physical measurements are first-class product fields
+- circularity notes are stored on the product as nullable JSON with optional `recyclability`, `disassemblability`, and `remanufacturability` fields
 - ownership is attached to the user level
 - materials, product types, and media can be linked without making every field mandatory

 ## File storage and media
 
-Media is treated as part of the record, not as decoration. In practice, images often carry a large part of the evidential value of a product record. Files and images support polymorphic associations, allowing them to be linked to products, materials, or product types. Videos are currently linked via URLs rather than stored directly.

+`video` sits in this context even though a video attaches to a product. The platform stores a URL and its metadata, which makes the row a media reference like the other two.
+
+## Camera plugin
+
+The Raspberry Pi camera integration owns two tables. `camera` holds a paired device and the relay credential that authenticates it; `recording_session` links a live broadcast to the video row it produces. [RPi camera plugin](/architecture/rpi-cam/) covers the pairing and streaming path these tables support.

-<div class="relab-section-intro">
-RELab runs as a self-hosted Docker Compose stack sized for a single VPS.
-</div>
-
-## Compose Service Topology
-
-The deployed stack is defined entirely in Docker Compose. Core services run in all environments. Some deployments also enable additional operational services such as migrations, backups, the Cloudflare tunnel, and optional log/trace shipping to an external monitoring stack.
-

-    Cloudflared -->|proxies inbound traffic| Backend
-    Backend -->|OTLP traces/metrics| OTel
-    Backend -->|container logs via Docker driver| Loki
-```
-
-Backup services are enabled through Compose profiles. Telemetry is opt-in through host-level environment variables: `LOKI_URL` enables the optional Loki logging overlay, and `OTEL_EXPORTER_OTLP_ENDPOINT` enables backend OTLP export.
-
-For formal architecture views of the platform as a whole, see [C4 Architecture Diagrams](../c4-diagrams/).
-
-## Storage and Backups
-
-- PostgreSQL stores the primary application state.
-- Uploaded files and images are stored on disk and served by the backend.
-- Database dumps and user-uploaded files are backed up regularly to cloud storage.
-- Alembic migrations move schema state forward in a controlled way.
-
-## Quality Controls
-
-- backend: unit and integration tests, linting, and type checking
-- frontend-app: Jest tests for app logic and UI components
-- frontend-web: Vitest and Playwright coverage for the public site
-- docs: formatting, spelling checks, and build smoke tests
-
-The repository also includes dependency maintenance, container scanning, performance baselines, and repository-level checks through GitHub Actions.
-
-## Operational Considerations
-
-- Redis is used both for caching and parts of the authentication and token flow. Partial Redis outages have user-facing effects.
-- Uploaded media is part of the research record and should be treated as primary data, not as disposable assets.
-- Production secrets and origin/host configuration matter; the backend enforces stricter checks outside development.
-- Telemetry is optional. When enabled, the backend exports OTLP traces and metrics to an external collector, while Docker ships container logs to Loki through the optional overlay.
-- The Compose-based setup is easy to reason about, but scaling and secret rotation are less automated than in a larger platform setup. That trade-off is deliberate.

-title: Engineering Configuration
-description: Version policy, manifest ownership, and configuration rules for the RELab repo.
-owner: docs
-status: reviewed
-lastReviewed: '2026-04-23'
----
-
-This page documents the supported configuration contract for RELab itself: runtime versions, manifest ownership, environment files, task runners, and the review rules for infra/meta changes.
-
-## Version Policy
-
-- Python: `3.14` is the supported repo-wide version.
-- Node.js: `22.x` is the supported repo-wide version.
-- pnpm: `10.x` is the supported package-manager contract for frontend projects.
-- `uv` is the supported Python package and environment manager.
-
-The source-of-truth files are:
-
-- root `pyproject.toml`
-- root `.python-version`
-- per-project manifests in `backend/`, `docs/`, `frontend-app/`, and `frontend-web/`
-
-## Manifest Ownership
-
-- Root `justfile`: repo-wide orchestration and cross-project workflows.
-- Per-project `justfile`: local adapter for one subproject only.
-- `pyproject.toml`: Python dependencies, dependency groups, and Python tool configuration.
-- `package.json`: frontend dependencies, runtime/tooling engine policy, and thin script wrappers.
-- Env files: runtime and build-time configuration only. They should not carry procedural logic.
-- GitHub workflow YAML: CI/CD wiring only. If logic is complex, move it to a versioned script or reusable action.
-
-## Environment Model
-
-RELab uses four distinct configuration surfaces:
-
-- root `.env`: host-local secrets and operations settings used by Compose interpolation, backups, ingress, and optional telemetry shipping
-- root `.env.<env>.compose`: committed, non-secret per-environment Compose settings (`prod` and `staging`)
-- backend `.env.{dev,staging,prod,test}`: backend runtime settings
-- `frontend-app/.env.*`: build-time public Expo settings
-- `frontend-web/.env.*`: build-time public Astro settings
-
-Rules:
-
-- committed `*.example` files are the authoritative templates for human-managed environments
-- committed `.env.<env>.compose` files are the authoritative non-secret deploy defaults for their environment
-- committed test env files are allowed only when their values are intentionally non-secret
-- production/staging examples must leave secret values blank
-- Compose may override hostnames such as `DATABASE_HOST` or `REDIS_HOST`, but the variables still belong in the backend contract
-- public frontend variables must stay framework-native: `EXPO_PUBLIC_*` for Expo and `PUBLIC_*` for Astro
-
-### Telemetry variables (prod/staging only)
-
-Telemetry connection settings now live in one place only: the host's root `.env`. The deploy overlay reads them from there; the committed `.env.prod.compose` / `.env.staging.compose` files do not duplicate them, and dev/CI ignore them.
-
-- `LOKI_URL`: push endpoint for a central Loki instance. When set to a non-empty value, the root `justfile` auto-includes `compose.logging.loki.yaml`, which overlays the Loki Docker log driver onto every service. Hosts without this variable keep Docker's default `json-file` driver. Install the driver plugin once per host before setting the variable:
-
-  ```bash
-  docker plugin install grafana/loki-docker-driver:latest --alias loki --grant-all-permissions
-  ```
-
-- `OTEL_EXPORTER_OTLP_ENDPOINT`: OTLP HTTP endpoint for traces and metrics. The backend exports when set; leaving it empty disables OTLP cleanly.
-
-- `OTEL_EXPORTER_OTLP_HEADERS`: optional OTLP auth headers passed through to the backend container when your collector requires them.
-
-See [Engineering Operations → Telemetry](../engineering-ops/#telemetry) for the full flow.
-
-## Local Workflow
-
-Preferred path:
-
-```bash
-cp .env.example .env
-cp backend/.env.dev.example backend/.env.dev
-just setup
-just dev
-just ci
-```
-
-Focused work is still supported from subproject directories, but the root `justfile` is the primary interface and the root full-stack devcontainer is the primary onboarding path.
-
-## Pre-commit vs CI
-
-Keep in pre-commit:
-
-- formatting and policy checks that are fast and deterministic
-- lockfile integrity checks
-- secret scanning and obvious file hygiene issues
-
-Keep in CI:
-
-- multi-project validation
-- Compose rendering
-- environment contract auditing
-- browser E2E and container/image checks
-- expensive audits or checks that require broader system context
-
-## Infra Review Checklist
-
-Before merging an infra/meta change, check:
-
-- does this add a new config surface that could live in an existing manifest instead?
-- does this duplicate an existing `just`, `package.json`, or workflow contract?
-- does this introduce environment-specific drift across dev/staging/prod/test?
-- does it keep the single-server Compose deployment model understandable?
-- if it changes env vars, are the example files, docs, and validation rules updated together?

-title: Engineering Operations
-description: The supported engineering, validation, and deployment path for RELab.
-owner: docs
-status: reviewed
-lastReviewed: '2026-04-23'
----
-
-This page documents the supported engineering and delivery path for RELab as of 2026. The goal is a lean self-hosted platform that stays easy to understand and operate on one server.
-
-## Delivery Model
-
-- Docker Compose is the only supported runtime for staging and production.
-- `compose.yaml` is the shared base topology.
-- `compose.dev.yaml`, `compose.ci.yaml`, and `compose.deploy.yaml` are the supported environment overlays (dev, CI, long-lived deploys). `compose.e2e.yaml` is a standalone full-stack E2E harness.
-- A single `compose.deploy.yaml` covers **both prod and staging**. The host-level root `.env` provides secrets and optional telemetry endpoints; the committed `.env.prod.compose` / `.env.staging.compose` files provide the non-secret environment selection and build/runtime knobs.
-- Docker Compose on the server remains the source of truth for deploy and runtime operations.
-- GitHub Actions currently handle validation, security checks, release management, and the backend performance baseline.
-
-## Canonical Local Commands
-
-Use the root `justfile` as the primary interface:
-
-```bash
-just setup
-just ci
-just test
-just test-integration
-just security
-just docker-smoke
-```
-
-These commands are the supported local mirrors of CI behavior.
-The configuration contract behind them is documented in [Engineering Configuration](../engineering-config/).
-
-## CI and Release Lanes
-
-- `Validate`: PR and push validation, Compose rendering checks, workflow linting, targeted subsystem tests, and full-stack E2E when backend or app changes justify it.
-- `Security`: secret scanning, dependency audits, image scanning, and SBOM generation.
-- `Release Please`: versioning, changelog updates, and release PR/tag management.
-- `Ops`: backend performance baselines only.
-
-## Deploy Flow
-
-The supported deploy path is intentionally simple and applies to both staging and production.
-
-**One command, one compose file, one checkout. The host's root `.env` supplies secrets and optional telemetry; the committed `.env.<env>.compose` file supplies the environment shape.**
-
-### First-time host setup (common to prod and staging)
-
-```bash
-git clone git@github.com:CMLPlatform/relab.git
-cd relab
-
-# 1. Root .env — compose interpolation (tunnel token, backup paths, deploy target)
-cp .env.example .env
-$EDITOR .env
-
-# 2. Backend runtime env — FastAPI settings, DB URLs, secrets
-cp backend/.env.prod.example backend/.env.prod          # on a prod host
-# OR
-cp backend/.env.staging.example backend/.env.staging    # on a staging host
-$EDITOR backend/.env.{prod,staging}
-```
-
-### On a prod VM
-
-Use the prod compose env file alongside the host's root `.env`:
-
-```bash
-just prod-up YES
-# or equivalently:
-#   docker compose --env-file .env --env-file .env.prod.compose \
-#     -f compose.yaml -f compose.deploy.yaml up --build -d
-```
-
-Brings up project `relab_prod` with `ENVIRONMENT=prod` and `WEB_CONCURRENCY=4`. Then `just prod-migrate YES`, verify `/live` and `/health`, and use `just prod-logs` / `just prod-down YES` as needed.
-
-### On a staging VM
-
-Use the staging compose env file alongside the same host-level `.env` pattern:
-
-```bash
-just staging-up YES
-# or equivalently:
-#   docker compose --env-file .env --env-file .env.staging.compose \
-#     -f compose.yaml -f compose.deploy.yaml up --build -d
-```
-
-Brings up project `relab_staging` with `ENVIRONMENT=staging` and `WEB_CONCURRENCY=2`. Then `just staging-migrate YES`, verify health, and iterate.
-
-### Upgrading either host
-
-```bash
-git pull
-just prod-up YES      # prod host
-just staging-up YES   # staging host
-```
-
-### Optional profiles
-
-- Backups: append `--profile backups` to the `up` command (or use `just prod-backup-up YES`).
-- Telemetry: see [Telemetry](#telemetry) below.
-
-## Telemetry
-
-Logs, traces, and metrics from prod and staging ship to a **central monitoring stack** (Grafana + Loki + Tempo + Prometheus) that lives outside this repo. Dev and CI never ship telemetry. The host's root `.env` is the single place where operators set the Loki and OTLP connection settings used by deploys.
-
-### Logs → Loki
-
-Logs use the [Loki Docker log driver](https://grafana.com/docs/loki/latest/send-data/docker-driver/) rather than an in-cluster agent. To enable on a host:
-
-1. Install the driver plugin (once per host):
-
-   ```bash
-   docker plugin install grafana/loki-docker-driver:latest --alias loki --grant-all-permissions
-   ```
-
-1. Set `LOKI_URL` in the host's root `.env` (the push endpoint of your central Loki).
-
-The root `justfile`'s `prod_compose` / `staging_compose` recipes auto-include [`compose.logging.loki.yaml`](../../../../../compose.logging.loki.yaml) when `LOKI_URL` is set. Hosts without `LOKI_URL` keep Docker's default `json-file` driver — no action required.
-
-Logs carry labels for `service`, `env`, and `host`. Keep label cardinality low: use LogQL filters (`| json | user_id = "…"`) for high-cardinality fields rather than adding them as labels.
-
-### Traces and metrics → OTLP
-
-The FastAPI backend exports OTLP when `OTEL_EXPORTER_OTLP_ENDPOINT` is set in the host's root `.env`. Leave it unset to disable. If your collector requires auth, also set `OTEL_EXPORTER_OTLP_HEADERS` in that same root `.env`; `compose.deploy.yaml` passes the endpoint through to the backend container and the OTEL SDK reads the headers from the container environment.
-
-### Hosting the monitoring stack
-
-The central stack is maintained as its own project (see the monitoring repo). It's meant to be reachable from prod/staging hosts over a private network (Cloudflare Tunnel, Tailscale, WireGuard) — never over the public internet.
-
-### Dev-laptop shortcut
-
-The root `justfile` defines a `staging_compose` recipe that uses `--env-file .env.staging.compose` alongside the host's root `.env`, so a dev laptop can spin up a staging-shaped stack without rewriting `.env`. See `just --list` for the `staging-*` recipes.
-
-## Secrets and Host Expectations
-
-The server is expected to have:
-
-- a checked-out copy of the RELab repo in the deployment directory you operate from
-- Docker Compose available
-- environment-specific `.env` files already provisioned outside the repository
-- separate staging and production backend env files populated from `backend/.env.staging.example` and `backend/.env.prod.example`
-
-## Maintainer Notes
-
-Some internal `just` recipes still exist for occasional maintenance work such as backup profiles, smoke-test breakdowns, reset flows, or perf threshold refresh. They are intentionally hidden from the default interface and are not part of the supported day-to-day contributor or operator path.
-
-## Backups and Recovery
-
-- If you operate backup profiles on the server, treat them as explicit operational services rather than part of the default deploy path.
-- Migrations are idempotent and should be run explicitly during deploys.
-- Roll back application code by redeploying a prior known-good git ref or commit.
-- Roll back schema only with a reviewed migration plan; do not assume every migration is safely reversible in production.

-lastReviewed: '2026-04-23'
----
-
-## Hosted Use
-
-If you just want to use RELab, start here:
-
-[app.cml-relab.org](https://app.cml-relab.org)
-
-No local setup is required.
-
-## Self-Hosting
-
-Self-hosting makes sense for evaluation, institutional deployment, offline use, or local development. If your main goal is contributing code, [CONTRIBUTING.md](https://github.com/CMLPlatform/relab/blob/main/.github/CONTRIBUTING.md) is the better starting point.
-
-This page is about running the stack. For manifest conventions, tooling policy, and contributor workflow, use the engineering and contributing docs instead.
-
-### Prerequisites
-
-- [Docker Desktop](https://docs.docker.com/get-started/get-docker/)
-- [`just`](https://just.systems/man/en/) is optional but recommended
-
-## Local Docker Setup
-
-1. Clone the repository.
-
-   ```bash
-   git clone https://github.com/CMLPlatform/relab
-   cd relab
-   ```
-
-1. Install local tooling if you plan to modify code.
-
-   ```bash
-   just setup
-   ```
-
-1. Configure the backend environment.
-
-   ```bash
-   cp backend/.env.dev.example backend/.env.dev
-   ```
-
-1. Run the first migration pass.
-
-   ```bash
-   just dev-migrate
-   ```
-
-   If you also need CPV or HS taxonomy seeding in the migration container:
-
-   ```bash
-   BACKEND_MIGRATIONS_INCLUDE_TAXONOMY_SEED_DEPS=true docker compose --profile migrations up --build migrator
-   ```
-
-1. Start the stack.
-
-   ```bash
-   just dev
-   ```
-
-   If you do not want file watching, use `just dev-up` instead.
-
-1. Open the local services.
-
-   - Platform: <http://127.0.0.1:8010>
-   - API: <http://127.0.0.1:8011>
-   - Docs: <http://127.0.0.1:8012>
-   - App frontend: <http://127.0.0.1:8013>
-
-1. Verify the backend is healthy.
-
-   ```bash
-   curl http://127.0.0.1:8011/health
-   ```
-
-1. Run checks if needed.
-
-   ```bash
-   just ci
-   just test
-   ```
-
-## Production / Staging Deployment
-
-Deploys use a single compose overlay, `compose.deploy.yaml`. The host's root `.env` decides whether the stack comes up as prod or staging — one file, one command, no extra flags. Cloudflare Tunnel remains the supported ingress path. The current operational path is manual on the server: pull the repo, run the deploy stack, run migrations, verify health.
-
-1. Configure a Cloudflare tunnel.
-
-   - Set up a domain and a remotely managed tunnel in Cloudflare.
-   - Forward traffic to `app-site:8081`, `web-site:8081`, `api:8000`, and `docs-site:8000`.
-
-1. Copy `.env.example` to `.env` and fill in values.
-
-   ```bash
-   cp .env.example .env
-   ```
-
-   - **Prod host**: set `TUNNEL_TOKEN=<prod token>`; leave the commented "staging overrides" block commented. Defaults resolve to `ENVIRONMENT=prod`, `WEB_CONCURRENCY=4`, project `relab_prod`.
-   - **Staging host**: uncomment the staging block (`APP_ENV=staging`, `COMPOSE_PROJECT_NAME=relab_staging`, `WEB_CONCURRENCY=2`, `BUILD_MODE=staging`, `PUBLIC_SITE_URL=…`, `CSP_API_ORIGIN=…`) and set `TUNNEL_TOKEN=<staging token>`.
-
-1. Configure the backend runtime environment for this host.
-
-   ```bash
-   cp backend/.env.prod.example backend/.env.prod          # on a prod host
-   # OR
-   cp backend/.env.staging.example backend/.env.staging    # on a staging host
-   ```
-
-1. Start the stack.
-
-   ```bash
-   just prod-up YES
-   ```
-
-   In the current setup, deployment is done directly on the server.
-
-1. Run migrations.
-
-   ```bash
-   just prod-migrate YES
-   ```
-
-   If you also need taxonomy seeding in the migration container:
-
-   ```bash
-   BACKEND_MIGRATIONS_INCLUDE_TAXONOMY_SEED_DEPS=true docker compose -p relab_prod -f compose.yaml -f compose.deploy.yaml --profile migrations up --build migrator
-   ```
-
-1. Manage the running stack.
-
-   ```bash
-   just prod-logs
-   just prod-down YES
-   ```
-
-### Optional: central telemetry
-
-If you run a central monitoring stack (Grafana + Loki + Tempo + Prometheus), prod and staging can ship to it without any code changes:
-
-1. Install the Loki Docker driver plugin on the host (once):
-
-   ```bash
-   docker plugin install grafana/loki-docker-driver:latest --alias loki --grant-all-permissions
-   ```
-
-1. Set `LOKI_URL` (and optionally `OTEL_EXPORTER_OTLP_ENDPOINT`) in the host's root `.env`. The `prod-up` / `staging-up` recipes auto-include `compose.logging.loki.yaml` when `LOKI_URL` is non-empty. Hosts without the variable keep Docker's default `json-file` driver.
-
-See the [engineering ops telemetry section](/architecture/engineering-ops/#telemetry) for the full flow.
-
-## Staging Deployment
-
-Staging is a first-class operational environment and follows the same manual server-side flow as production.
-
-1. Configure the backend staging environment.
-
-   ```bash
-   cp backend/.env.staging.example backend/.env.staging
-   ```
-
-1. Start the staging stack.
-
-   ```bash
-   just staging-up YES
-   ```
-
-1. Run migrations.
-
-   ```bash
-   just staging-migrate YES
-   ```
-
-1. Manage the running stack.
-
-   ```bash
-   just staging-logs
-   just staging-down YES
-   ```
-
-## Raspberry Pi Camera Plugin
-
-If you want camera-assisted capture, see the external plugin repository:
-
-[Raspberry Pi Camera Plugin](https://github.com/CMLPlatform/relab-rpi-cam-plugin)
-
-The plugin uses **WebSocket relay** — the RPi connects outbound to the backend, so no public IP or port forwarding is needed. The quickest setup is **automatic pairing**: set `PAIRING_BACKEND_URL` on the RPi, boot it, and enter the displayed pairing code in the app. See the [plugin install guide](https://github.com/CMLPlatform/relab-rpi-cam-plugin/blob/main/INSTALL.md) and the [platform camera guide](/user-guides/rpi-cam/) for details.
-If the Pi is headless, you can read the pairing code either from its local `/setup` page or from the `PAIRING READY` log line over SSH, `docker compose logs`, or `journalctl`.

-## Key Design Decisions
+## Key design decisions
+
+- Pairing, relay orchestration, capture storage, and YouTube coordination stay in the main backend, which acts as the control plane.
+- There are two contract layers: a public app-facing API plus a smaller private device contract for pairing, relay, and uploads (see [Protocol boundaries](#protocol-boundaries)).
+- After pairing, the app can switch to LAN-direct access with a device-local API key, for lower-latency preview and capture when the device is reachable locally.
+- Cameras pair through a short-lived code and receive runtime relay credentials from the backend. Operators do not manually copy long-lived API keys in the normal path.
+- Captured images are stored in Relab's file storage and linked to the originating product or component record automatically.
+- YouTube streaming is optional and mediated through the backend's OAuth connection to YouTube. The device streams directly to YouTube once authorized.
+
+## Protocol boundaries
+
+The plugin uses three separate contracts:
+
+- **App REST API**: `/v1/plugins/rpi-cam/cameras/*` for app-facing camera CRUD, status, capture commands, telemetry, local-access bootstrap, and stream controls.
+- **Device REST API**: `/v1/plugins/rpi-cam/device/cameras/*` for Pi-originated callbacks such as image upload, preview thumbnail upload, and self-unpair. These routes authenticate with short-lived device assertions rather than a user session.
+- **Device WebSocket protocol**: `/v1/plugins/rpi-cam/ws/connect` for the persistent outbound relay tunnel from the Pi to the backend. It is a non-browser endpoint: the Pi authenticates with a short-lived bearer device assertion, production pairing returns a `wss://` URL, browser `Origin` handshakes are rejected, WebSocket compression is disabled, and frame/queue sizes are bounded.
+
+OpenAPI covers the HTTP routes; see the [API reference overview](/api-reference/). The WebSocket tunnel is a separate protocol contract and is not part of the generated REST clients.
+
+### WebSocket relay envelope
+
+The backend sends command envelopes to the device:
+
+```json
+{
+  "id": "request-id",
+  "method": "POST",
+  "path": "/captures",
+  "params": {},
+  "body": {
+    "product_id": 123,
+    "description": "Front panel"
+  },
+  "headers": {}
+}
+```
+
+The device replies with a matching response envelope. The shared model package owns the exact envelope schema so the backend and plugin stay in lockstep.
+
+The relay allowlist lives in the shared `relab_rpi_cam_models` package and is
+enforced by both the backend and the plugin, so there is a single route list to
+maintain.
+
+Captured image bytes do not travel through the WebSocket. After a capture command succeeds, the Pi uploads the file and metadata directly to `/v1/plugins/rpi-cam/device/cameras/{camera_id}/image-upload`.
 
-- **Backend as control plane**: Pairing, relay orchestration, capture storage, and YouTube coordination stay in the main backend.
-- **Two contract layers**: backend OpenAPI remains the public app-facing contract, while a smaller shared private device contract covers pairing payloads, relay envelopes, local-access bootstrap, and Pi-initiated upload acknowledgements.
-- **Optional local direct mode**: After pairing, the app can switch to LAN-direct access for lower-latency preview and capture when the device is reachable locally.
-- **Relay-first registration**: Cameras pair through a short-lived code and receive runtime relay credentials from the backend; operators do not manually copy long-lived API keys in the normal path.
-- **Media storage**: Captured images are stored in RELab's file storage and linked to the originating product or component record automatically.
-- **Optional YouTube integration**: Streaming is mediated through the backend's OAuth connection to YouTube. The device streams directly to YouTube once authorised.
+### Device callback routes
 
-## Contract Ownership
+Pi-originated HTTP callbacks are plugin-scoped, keeping device routes namespaced to the camera plugin:
 
-- **Frontend -> backend** uses only backend-owned public routes and schemas.
-- **Backend -> plugin** uses a smaller private device seam: pairing register/poll payloads, relay command/response envelopes, local-access info, and direct upload/self-unpair acknowledgements.
-- **Shared models** exist to keep that private seam typed and versioned without leaking plugin implementation details into the frontend contract.
+- `POST /v1/plugins/rpi-cam/device/cameras/{camera_id}/image-upload`
+- `POST /v1/plugins/rpi-cam/device/cameras/{camera_id}/preview-thumbnail-upload`
+- `DELETE /v1/plugins/rpi-cam/device/cameras/{camera_id}/self`

+## Security architecture
 
-## Backend Domain Structure
+Relab is a single backend application, not a microservice fleet: authorization lives in FastAPI route dependencies, public traffic enters through Cloudflare Tunnel, and PostgreSQL and Redis stay on internal networks. The full trust-boundary model, asset inventory, and hardening posture are documented in [Security and hardening](/operations/security/).
 
-The backend is organised mainly by domain rather than by HTTP verb alone:

-## Runtime Behavior
-

-- initializes Redis and API caching
-- creates storage directories for uploads
-- mounts static and upload-backed routes
-- prepares shared outbound HTTP clients
-- starts background cleanup infrastructure
-
-## Design Priorities
+## Design priorities
 
 - keep the data model explicit and inspectable
 - support authenticated data entry from a dedicated app
 - allow public and private API surfaces to coexist
 - preserve a path toward dataset publication and external reuse
-- support FAIR-style reuse through open interfaces and documented structure
-- keep the data model suitable for later benchmarking and AI-assisted enrichment
-- avoid unnecessary infrastructure complexity for a PhD-scale project
+- keep identifiers and exports stable enough to link with other datasets
+- avoid infrastructure complexity that isn't justified by the project scale
+
+Relab is a modular monolith, and stays one until a real deployment or runtime
+boundary justifies a split. The backend is organized around explicit bounded
+contexts: identity and access, data collection, reference data, media and
+storage, statistics, and device integration.

-## Research Motivation
-
-Primary product data — material makeup, component structure, circularity-relevant properties — is still hard to obtain for many durable goods. RELab takes a bottom-up approach: instead of relying on producer-controlled information flows, the platform lets repairers, refurbishers, dismantlers, recyclers, and citizen scientists contribute structured observations directly, and is designed to interoperate with existing industrial-ecology databases rather than stand alone.

+title: Deployment and operations
+description: The self-hosted Relab deployment topology and its operational trade-offs.
+---
+
+Relab runs as a self-hosted Docker Compose stack sized for a single VPS.
+
+## Compose service topology
+
+The deployed stack is defined entirely in Docker Compose. Core services run in all environments. Some deployments also enable additional operational services such as migrations, backups, the Cloudflare tunnel, and optional log/trace shipping to an external monitoring stack.
+
+```mermaid
+---
+config:
+    layout: elk
+---
+graph TD
+    accTitle: Deployment Compose service topology
+    accDescr: The core services are the FastAPI backend, PostgreSQL, Redis, ClamAV, user media storage, the Expo app, the Astro landing page, and the Starlight docs site. They run alongside optional operational services for migrations, backups, the Cloudflare tunnel, and OTLP telemetry export from both the backend and an Alloy log collector. The backend is the hub, talking to the database, cache, malware scanner, and external monitoring collector.

+    Backend -->|scan uploads| ClamAV
+    Backend -->|OTLP traces/metrics/logs| OTel
+    Alloy -->|container stdout via OTLP| OTel
+```
+
+Backup services are enabled through Compose profiles. Telemetry is opt-in through one host-level environment variable: `OTEL_EXPORTER_OTLP_ENDPOINT` enables the backend's OTLP export and auto-includes the Alloy overlay that ships every other container's stdout.
+
+## Supported delivery path
+
+- Docker Compose is the runtime for staging and production.
+- `compose.yaml` is the shared base topology.
+- `compose.dev.yaml`, `compose.ci.yaml`, and `compose.deploy.yaml` are the supported environment overlays.
+- The same `compose.deploy.yaml` is used for prod and staging. Committed `deploy/env/*.compose.env` files select the environment and public origins; Compose maps those values to backend, app, docs, and www variable names at each service boundary. Docker Compose reads the host-level root `.env` for host-local operator inputs such as tunnel tokens, OAuth client IDs, email sender metadata, the initial superuser identity, telemetry endpoints, and backup paths. Manual shell helpers use exported environment variables instead of parsing `.env`.
+- GitHub Actions validate changes, run security checks, and maintain release automation, but deploys are still operated from the server checkout.
+- Cloudflare DNS and Tunnel public hostname configuration lives in `infra/cloudflare/`. Compose still owns the runtime services; OpenTofu owns only the public edge.
+
+Docker development and E2E ports bind to localhost by default. For Expo testing from another device over a LAN, run the Expo dev server directly from `app/` on the host instead of using the Docker app service.
+
+The root `justfile` is the supported local interface for full-stack checks:
+
+```bash
+just setup
+just ci
+just test
+just test-integration
+just security
+just docker-smoke
+```
+
+Focused subrepo work should use the subrepo `justfile`.
+
+## Cloudflare edge as code
+
+Relab manages public hostnames through OpenTofu in `infra/cloudflare/`. The
+configuration is intentionally narrow: DNS records, separate prod/staging
+Cloudflare Tunnels, Tunnel ingress rules, and a final `http_status:404` catch-all
+for unknown hostnames. It does not manage app secrets, Compose services,
+PostgreSQL, Redis, storage, backups, or host deployment.
+
+The current origins point at Compose services such as `http://api:8000` and
+`http://app:8081`.
+
+Use separate prod and staging OpenTofu workspaces/state. Before applying this to
+an existing Cloudflare account, import the current DNS records and tunnels, then
+run `just cloudflare-plan staging` or `just cloudflare-plan prod` until the plan
+shows only intentional drift. Apply with `just cloudflare-apply <env> YES` after
+reviewing the plan. Export Cloudflare/OpenTofu credentials as environment variables before running
+these commands. Do not commit Cloudflare tokens, tunnel tokens, or state files.
+
+Public hostname changes should start in `infra/cloudflare/`. Do not add wildcard
+DNS records unless there is a concrete operational need and the blast radius has
+been reviewed.
+
+## Network segmentation policy
+
+The deploy stack keeps segmentation intentionally small: public-facing services use the `edge` network, data services use the internal `data` network, upload scanning uses the private `scanning` network, and only the API bridges the networks it needs. This follows the OWASP network segmentation model at Compose scale without adding extra proxies, VLANs, or host firewall rules to the repo.
+
+| Service group | Compose networks | Host ports in prod/staging |
+| --- | --- | --- |
+| `cloudflared`, `docs`, `app`, `www` | `edge` only | none |
+| `api` | `edge`, `data`, `scanning` | none |
+| `postgres`, `redis`, `migrator`, `backup` | `data` only | none |
+| `clamav` (`scanning` profile only) | `scanning` only | none |
+
+`just compose-config` validates that the supported Compose overlays render for dev, prod, and staging.
+`just deploy-secrets-check` validates that rendered Compose secrets point at the expected `secrets/<env>/` files, that the directory and file modes are correct (directory `0700`, files `0644`, with remediation printed on mismatch), and that no secret is left at a placeholder value.
+
+## Backend egress
+
+Backend outbound HTTP is restricted to `OUTBOUND_HTTP_ALLOWED_URLS`. See
+[Security and hardening](/operations/security/#backend-egress) for the policy
+model.
+
+## Transport security
+
+Production and staging are HTTPS-only behind Cloudflare Tunnel. The Cloudflare
+edge configuration in `infra/cloudflare/` enforces TLS 1.2 or newer, enables TLS
+1.3, redirects HTTP requests to HTTPS before they reach the tunnel, and owns
+Relab-specific Cloudflare rate limiting policy for auth, upload, and RPi camera
+traffic.
+
+Every deployed browser-facing origin emits:
+
+```http
+Strict-Transport-Security: max-age=63072000; includeSubDomains
+```
+
+Static frontends set this in Caddy; the API sets it from FastAPI in `prod` and `staging`. `preload` is omitted; the full `cml-relab.org` subdomain inventory has not been verified for preloading.
+
+PostgreSQL and Redis stay on the private Compose `data` network, so
+`DATABASE_TLS=false` and `REDIS_TLS=false` are intentional defaults. If either
+service moves off that trusted network, enable validating TLS with
+`DATABASE_TLS=true` or `REDIS_TLS=true`; set the matching CA file variable for
+private CAs. See [Security and hardening](/operations/security/) for the broader
+trust-boundary model.
+
+Supported browsers must implement HTTPS, HSTS, Content Security Policy, host-prefixed secure cookies, SameSite cookies, CORS preflight enforcement, and the modern cross-origin isolation headers used by Relab (`Cross-Origin-Opener-Policy` and `Cross-Origin-Resource-Policy`). Unsupported browsers are not given a fallback security mode; they may fail to authenticate, fail to load protected media, or be blocked by browser policy.
+
+## Deploy flow
+
+For a new host, clone the repo, create the root `.env`, review the relevant `deploy/env/*.compose.env` file, create secret files, validate the render, then start the deploy stack and run migrations:
+
+```bash
+cp .env.example .env
+# Fill required values in .env.
+just deploy-secrets-template prod
+# Replace every placeholder under secrets/prod/.
+just compose-config
+just deploy-secrets-check
+just prod-up YES scanning
+just prod-migrate YES
+```
+
+Staging follows the same pattern with the staging env files and `staging-*` recipes. Upgrades are intentionally boring: pull a known-good revision, bring the stack up again, run migrations, and verify `/live` and `/health`. The `/live` endpoint is the shallow backend process check used by Compose, while `/health` is the operator-facing readiness check that verifies PostgreSQL and Redis.
+
+ClamAV malware scanning is enabled by default: `MALWARE_SCAN_ENABLED=true` ships in `.env.example`, and `deploy_ops.sh` refuses to bring the stack `up` when that flag is anything but `false` unless the `scanning` Compose profile is also passed. `up` starts no backup service — the backup is a one-shot owned by a systemd timer (see the install guide's "Scheduling backups") — so `scanning` is normally the only profile you pass: `just prod-up YES scanning` or `just staging-up YES scanning`. To opt out, set `MALWARE_SCAN_ENABLED=false` in the root `.env` and omit the `scanning` profile. Uploaded files are then stored without a malware scan; treat that as an explicit, temporary accepted risk, not a default. When scanning is enabled, the `clamav` service keeps its signature database in the persisted `clamav_db` volume; first boot with an empty volume can wait several minutes while signatures download. Budget roughly 3-4 GiB of RAM for ClamAV so default signature reload and database testing behavior can stay enabled.
+
+The database role hardening is a breaking fresh-volume change. For an existing host, take a verified dump first, stop the stack, recreate the Postgres volume, start Postgres so `/docker-entrypoint-initdb.d` creates the least-privilege roles, run migrations, then restore the dump through the migration/admin path.
+For local rehearsal, use staging instead of production: `just staging-up YES`, `just staging-migrate YES`, `just backup staging` to seed the first snapshot, then `just restore-check staging`.
+
+## Storage and backups
+
+- PostgreSQL stores the primary application state.
+- Uploaded files and images are stored on disk and served by the backend.
+- Database dumps and user-uploaded files are backed up into an encrypted local restic repository under `BACKUP_HOST_DIR`.
+- Optional offsite copies use `restic copy`; WebDAV is supported through restic's rclone backend. When `RESTIC_OFFSITE_REPOSITORY` is set in `deploy/env/<env>.compose.env` (per environment — the root `.env` is shared by every stack on the host, so a value there would send production snapshots to staging's offsite repository), each backup cycle copies snapshots offsite at the end automatically. Backup cycles are driven by a host systemd timer (`deploy/systemd/relab-backup@.timer`), not by `up` — starting the stack does not schedule anything. The offsite step is skipped with a warning, rather than failing the run, while `secrets/<env>/rclone.conf` does not define the remote the repository names. `just backup-offsite-copy <env>` remains available as an ad-hoc, on-demand copy outside that cycle.
+- Alembic migrations move schema state forward in a controlled way.
+- `just restore-check staging` or `just restore-check prod` restores the latest database dump into a disposable Postgres container and verifies that it can be read.
+
+The deploy stack runs app-owned services with dropped Linux capabilities, `no-new-privileges`, PID/file descriptor limits, and read-only root filesystems where supported. The backup container runs as UID/GID `1001`; make sure the host restic directory under `BACKUP_HOST_DIR` is writable by that ID. On a first-time host, create it yourself before starting the stack. Docker creates missing bind-mount directories root-owned, and the backup container cannot then initialize the restic repository:
+
+```bash
+mkdir -p "${BACKUP_HOST_DIR:-./backups}/restic"
+sudo chown -R 1001:1001 "${BACKUP_HOST_DIR:-./backups}"
+```
+
+CI checks Dockerfile misconfigurations with Trivy and validates Cloudflare edge IaC with `just cloudflare-check`.
+Root deployment validation renders the supported Compose overlays with `just compose-config` and checks rendered secret file paths with `just deploy-secrets-check`.
+
+## Secrets and encrypted fields
+
+Most Relab data is protected by access control, not application-level encryption. Passwords are hashed, not encrypted. Public research records, uploaded media, public RPi camera keys, request IDs, and cache keys are not application-encrypted.
+
+`deploy/env/variables.toml` is the source-controlled runtime secret inventory. It lists the secret files Compose should render under `secrets/<env>/` and keeps the future Infisical path template beside that contract. Use `just env-inventory` from the repo root when onboarding a host or reviewing secret-file changes.
+
+The backend uses `DATA_ENCRYPTION_KEY` only for reversible sensitive values it must recover later, such as OAuth provider tokens and active YouTube broadcast keys. Cache payload signing uses the separate `CACHE_SIGNING_SECRET`, and OAuth state uses `OAUTH_STATE_SECRET`, so each key has one purpose. Keep these application secrets in gitignored Compose secret files under `secrets/<env>/`, not in committed files or backend env files.
+
+Backend app secrets, database role passwords, the Redis password, the restic repository password, and optional rclone config live in gitignored Compose secret files under `secrets/<env>/`. Required files are declared by the rendered Compose overlays; use `just deploy-secrets-template dev`, `just deploy-secrets-template staging`, or `just deploy-secrets-template prod` to create missing files and `just deploy-secrets-check` to verify that Compose points at the expected root secret files. The application role, migration role, and backup role are separate PostgreSQL users; the application role is not the schema owner.
+
+Keep configuration ownership narrow: `infra/cloudflare/` contains public edge
+configuration, `deploy/` contains committed non-secret runtime identity, the
+root `.env` contains host-local operator inputs, `secrets/`
+contains uncommitted operator-owned secret material, and `scripts/` contains
+repo-wide operational helpers that are too large for the root `justfile`.
+Backend dotenv files are local/test inputs only; prod and staging do not use
+backend `.env.<env>` files.
+
+### Rotation and break-glass
+
+For ordinary app secret rotation, replace the file under `secrets/<env>/`, restart the affected service, and verify `/live` and `/health`. For `AUTH_TOKEN_SECRET`, expect existing login/reset/verification tokens to become invalid. For OAuth or email provider secrets, rotate the upstream credential first, update the matching file, then restart `api`.
+
+Database role password rotation has two steps: change the PostgreSQL role password, then update the matching file under `secrets/<env>/` and restart the affected service (`api`, `migrator`, or `backup`). Redis rotation requires restarting both `redis` and consumers such as `api`.
+
+`DATA_ENCRYPTION_KEY` is break-glass material, not a routine restart-only secret. Rotating it requires a planned data re-encryption path and backup-retention review because older encrypted values and backups depend on the previous key.
+
+If a real secret is exposed outside the intended host, treat it as compromised: revoke or rotate it upstream, update the host file or root `.env` value, restart affected services, run health checks, and preserve enough incident notes to know what was exposed and when. Existing encrypted backups should be treated as depending on the old key until their retention window passes.
+
+## Telemetry
+
+Prod and staging can ship logs, traces, and metrics to a central monitoring stack outside this repo. Dev and CI do not ship telemetry.
+
+- `OTEL_EXPORTER_OTLP_ENDPOINT` is the switch for the whole telemetry path: the backend's OTLP traces, metrics and logs, plus the `compose.telemetry.yml` overlay.
+- `OTLP_AUTH_TOKEN` is the collector's bearer token. One operator input, two consumers: Compose folds it into the SDK's header format for the backend, and Alloy reads it directly.
+- `TELEMETRY_EDGE_KEY` is a second, weaker credential sent as an `X-Telemetry-Key` header. The Cloudflare WAF-skip rule for the telemetry hostname matches it instead of the bearer token, so the token never appears in a ruleset expression readable through the Cloudflare API. All three must be set together; `just deploy-secrets-check` enforces the pairing.
+- `OTEL_EXPORTER_OTLP_PROTOCOL` defaults to `http/protobuf`, pinned because the collector is reached through a tunnel that routes HTTPS only.
+
+Hosts without those variables keep the simpler local-only behavior. Keep monitoring endpoints private through a tunnel or private network; do not expose the monitoring stack directly to the public internet.
+
+## Operational considerations
+
+- Redis is used both for caching and parts of the authentication and token flow. Partial Redis outages have user-facing effects.
+- Uploaded media is part of the research record and should be treated as primary data, not as disposable assets.
+- Production secrets and origin/host configuration matter; the backend enforces stricter checks outside development.
+- Telemetry is optional. When enabled, the backend exports OTLP traces, metrics and logs to an external collector, and a Grafana Alloy agent forwards the remaining containers' stdout to the same endpoint. Nothing needs a Loki push hostname exposed, which matters because Loki has no authentication of its own.
+- The Compose-based setup is easy to reason about, but scaling and secret rotation are less automated than in a larger platform setup. That trade-off is deliberate.
+- Scheduled work (backup, watchdog, monthly restore verification) runs from systemd timers installed by `just timers-install <env>`; execution is deliberately local, since a backup needs the host's own volumes. Detection is not: each job pings a per-job dead-man's switch on success and reports its own output on failure, which is the one signal that does not travel through the same collector as everything else — so it still arrives when the telemetry path is itself what broke. `just watchdog <env>` remains as a local triage command that exits non-zero with an `ALERT[...]` line per failure.

+title: Installation and self-hosting
+description: Run Relab locally or self-host the stack in production or staging.
+---
+
+## Hosted use
+
+If you just want to use Relab, start here: [app.cml-relab.org](https://app.cml-relab.org).
+
+No local setup is required.
+
+## Self-hosting
+
+Self-hosting makes sense for evaluation, institutional deployment, offline use, or local
+development. This page is about running the stack. If your main goal is contributing code,
+[CONTRIBUTING.md](https://github.com/CMLPlatform/relab/blob/main/.github/CONTRIBUTING.md) covers
+tooling policy and contributor workflow.
+
+### Prerequisites
+
+- [Docker Desktop](https://docs.docker.com/get-started/get-docker/)
+- [`just`](https://just.systems/man/en/) is optional but recommended
+- Contributing code additionally requires [`uv`](https://docs.astral.sh/uv/), Node 26.x, and pnpm
+  11.x. See step 2 below and
+  [CONTRIBUTING.md](https://github.com/CMLPlatform/relab/blob/main/.github/CONTRIBUTING.md)
+
+## Local Docker setup
+
+1. Clone the repository.
+
+   ```bash
+   git clone https://github.com/CMLPlatform/relab
+   cd relab
+   ```
+
+1. Install local tooling if you plan to modify code.
+
+   ```bash
+   just setup
+   ```
+
+1. Create local backend secrets.
+
+   ```bash
+   just deploy-secrets-template dev
+   ```
+
+   Create `backend/.env.dev` only when you need backend-only local overrides such as OAuth, email,
+   or bootstrap settings. Replace values under `secrets/dev/` only when you need real local

+
+1. Start the containerized database/cache and run the first migration pass.
+
+   ```bash
+   just dev-db
+   just dev-migrate
+   ```
+
+   To seed sample data during migrations, run `SEED_DUMMY_DATA=true just dev-migrate`.
+
+   If you also need CPV or HS taxonomy seeding in the migration container:
+
+   ```bash
+   BACKEND_MIGRATIONS_INCLUDE_TAXONOMY_SEED_DEPS=true just dev-migrate
+   ```
+
+1. Start the stack.
+
+   ```bash
+   just dev
+   ```
+
+   If you do not want file watching, use `just dev-up` instead.
+
+1. Open the local services.
+
+   - API: <http://127.0.0.1:8010>
+   - App frontend: <http://127.0.0.1:8011>
+   - Docs: <http://127.0.0.1:8012>
+   - Landing site: <http://127.0.0.1:8013>
+
+1. Verify the backend is healthy.
+
+   ```bash
+   curl http://127.0.0.1:8010/health
+   ```
+
+1. Run checks if needed.
+
+   ```bash
+   just ci
+   just test
+   ```
+
+## Production and staging deployment
+
+Deploys use a single compose overlay, `compose.deploy.yaml`. Prod and staging are selected by
+committed non-secret Compose env files under `deploy/env/`, while each host keeps host-local
+interpolation values in the gitignored root `.env`. Cloudflare Tunnel remains the supported ingress
+path. The operational path is manual on the server: pull the repo, run the deploy stack, run
+migrations, verify health.
+
+1. Configure a Cloudflare tunnel.
+
+   - Set up a domain and a remotely managed tunnel in Cloudflare.
+   - Forward traffic to `app:8081`, `www:8081`, `api:8000`, and `docs:8000`.
+   - Public DNS and Tunnel ingress are managed in `infra/cloudflare/`.
+     For an existing Cloudflare account, import the current resources before
+     applying OpenTofu changes.
+
+1. Copy `.env.example` to `.env` and fill in the operator checklist.
+
+   ```bash
+   cp .env.example .env
+   ```
+
+   The root `.env` holds host-local values that Compose must interpolate. It can contain two types
+   of values:
+
+   - **Non-secret** values, such as OAuth client IDs, email sender metadata, the initial superuser
+     email, the backup host directory, and optional telemetry endpoints.
+   - **Secret** values only when a host helper or Compose interpolation requires them, such as
+     `CLOUDFLARE_TUNNEL_TOKEN` or optional authenticated telemetry URLs/headers.
+
+   For prod or staging, fill the required non-secret backend deploy inputs in `.env`:
+   `GOOGLE_OAUTH_CLIENT_ID`, `GITHUB_OAUTH_CLIENT_ID`, `EMAIL_PROVIDER`, email sender fields, and
+   `BOOTSTRAP_SUPERUSER_EMAIL`. Use the prod or staging Cloudflare tunnel token for
+   `CLOUDFLARE_TUNNEL_TOKEN`. Compose requires the shared email identity values; backend startup
+   validation enforces provider-specific settings. With `EMAIL_PROVIDER=smtp`, fill `SMTP_HOST`,
+   `SMTP_USERNAME`, and `secrets/<env>/smtp_password`. With `EMAIL_PROVIDER=microsoft_graph`, fill
+   the Microsoft Graph tenant/client/sender values and
+   `secrets/<env>/microsoft_graph_client_secret`.
+
+   Also review the upload ceilings and scanning inputs. Quotas are tiered by account role:
+   `MAX_UPLOAD_FILES_PER_USER` and `MAX_UPLOAD_BYTES_PER_USER_MB` cap ordinary `contributor`
+   accounts, while `MAX_UPLOAD_FILES_PER_LAB_USER` and `MAX_UPLOAD_BYTES_PER_LAB_USER_MB` cap `lab`
+   accounts. Neither lab value may be set below its contributor counterpart; the backend refuses to
+   start if it is. The quota ledger counts existing rows, so raise these limits before the first
+   start on a host with a large existing dataset. Otherwise, an owner whose existing uploads already
+   exceed the new limit is blocked from uploading entirely.
+
+   Every account starts as `contributor`, including on an upgrade that introduces roles. Promote
+   lab members with `PUT /v1/admin/users/{user_id}/role` and a body of `{"role": "lab"}` as a
+   superuser. To see who an upgrade would lock out before it bites, run
+   `just list-over-quota` in `backend/`: it reports, by account id, everyone already above the
+   quota their current role grants. `MALWARE_SCAN_ENABLED` controls ClamAV upload scanning and
+   must agree with whether the stack starts with the `scanning` Compose profile. See the two modes
+   in the "Start the stack" step below.
+
+   Environment identity and public origins live in `deploy/env/prod.compose.env` and
+   `deploy/env/staging.compose.env`. Each deploy env file defines the environment plus the four
+   public service URLs once: `API_PUBLIC_URL`, `APP_PUBLIC_URL`, `SITE_PUBLIC_URL`, and
+   `DOCS_PUBLIC_URL`.
+
+1. Review the non-secret deploy settings for this host.
+
+   Edit `deploy/env/prod.compose.env` or `deploy/env/staging.compose.env` only for committed public
+   URL changes. Keep application/runtime secrets out of `.env`; they belong under `secrets/<env>/`.
+   To inspect the runtime secret inventory, run:
+
+   ```bash
+   just env-inventory
+   ```
+
+1. Create the host-local Compose secret files.
+
+   ```bash
+   just deploy-secrets-template prod
+   ```
+
+   Replace every placeholder value under `secrets/prod/`. Use `just deploy-secrets-template staging`
+   for staging or `just deploy-secrets-template dev` for local development. Required secret
+   filenames are declared by the rendered Compose overlays and the runtime secret inventory in
+   `deploy/env/variables.toml`; `just deploy-secrets-check` verifies that every rendered secret
+   points at the expected `secrets/<env>/` file, that the directory and file modes are correct
+   (directory `0700`, files `0644`, with remediation printed on mismatch), and that no secret is
+   left at a placeholder value. Existing database volumes must be dumped and recreated before the
+   database role layout can take effect.
+
+1. Validate the deployment configuration.
+
+   ```bash
+   just compose-config
+   just deploy-secrets-check
+   ```
+
+1. Start the stack.
+
+   ClamAV upload scanning is enabled by default: `.env.example` ships `MALWARE_SCAN_ENABLED=true`,
+   and `deploy_ops.sh` refuses to bring the stack `up` when that flag is anything but `false` unless
+   the `scanning` profile is also passed. `up` starts no backup service — a systemd timer owns
+   backups (see "Scheduling backups" below) — so `scanning` is normally the only profile you pass.
+
+   - **With scanning (default):** keep `MALWARE_SCAN_ENABLED=true` in the root `.env` and pass the
+     `scanning` profile on every up/down. Budget roughly 3-4 GiB of extra RAM for ClamAV.
+
+     ```bash
+     just prod-up YES scanning
+     ```
+
+   - **Without scanning:** set `MALWARE_SCAN_ENABLED=false` in the root `.env` and start without
+     the `scanning` profile. Uploads are accepted unscanned; treat this as an explicit, temporary
+     accepted risk, not a default to keep long-term.
+
+     ```bash
+     just prod-up YES
+     ```
+
+   Leaving `MALWARE_SCAN_ENABLED=true` without the `scanning` profile fails all uploads closed.
+
+   For a local production-like backup rehearsal, prefer staging — `backup` seeds the
+   first snapshot, the same way the timer runs it:
+
+   ```bash
+   just staging-up YES
+   just staging-migrate YES
+   just backup staging
+   just restore-check staging
+   ```
+
+1. For Cloudflare edge changes, plan from the repo checkout or an ops machine
+   with OpenTofu and Cloudflare credentials.
+
+   Set the credentials and Cloudflare identifiers in the shell before planning:
+
+   ```bash
+   export CLOUDFLARE_API_TOKEN='...'
+   export TF_VAR_cloudflare_account_id='...'
+   export TF_VAR_cloudflare_zone_id='...'
+   export TF_VAR_cloudflare_zone_name='cml-relab.org'
+   ```
+
+   ```bash
+   just cloudflare-check
+   just cloudflare-plan staging
+   just cloudflare-plan prod
+   ```
+
+   :::danger
+   Only run `cloudflare-apply` against a greenfield Cloudflare zone, or after importing the
+   existing DNS records, tunnels, and rulesets into OpenTofu state. Applying against a
+   hand-configured zone tries to create everything from scratch: it duplicates DNS records,
+   creates a new tunnel whose id will not match the live `CLOUDFLARE_TUNNEL_TOKEN` (breaking
+   ingress), and can overwrite existing rulesets, since each Cloudflare phase allows only one
+   ruleset per zone.
+   :::
+
+   ```bash
+   just cloudflare-apply staging YES
+   just cloudflare-apply prod YES
+   ```
+
+   These commands also work with credentials from Bitwarden or another password
+   manager. Keep prod and staging state separate. Do not commit Cloudflare
+   tokens, tunnel tokens, or state files.
+
+1. Run migrations.
+
+   ```bash
+   just prod-migrate YES
+   ```
+
+   If you also need taxonomy seeding in the migration container:
+
+   ```bash
+   BACKEND_MIGRATIONS_INCLUDE_TAXONOMY_SEED_DEPS=true just prod-migrate YES
+   ```
+
+1. Manage the running stack.
+
+   ```bash
+   just prod-logs
+   just prod-down YES
+   ```
+
+### Scheduling backups
+
+Starting the stack does **not** schedule backups. The backup service is a one-shot: a
+systemd timer on the host runs it once a day and it exits. Install all three scheduled
+jobs (backup, watchdog, restore-check) once per environment — the installer renders the
+committed units with this host's checkout path, deploy user and `just` location, then
+enables the timers:
+
+```bash
+just timers-render                        # inspect what will be installed
+just timers-install staging               # renders, installs, enables (needs sudo)
+systemctl list-timers 'relab-*@staging.timer'   # confirm NEXT times are scheduled
+```
+
+The installer also seeds `/etc/relab/relab.env` with empty `PING_*` URLs. Fill
+them in with per-job [healthchecks.io](https://healthchecks.io) check URLs: until you
+do, the jobs run but their failures are invisible outside the host, and
+`just watchdog <env>` will keep saying so.
+
+`just backup <env>` runs one cycle immediately — use it for the first run, which
+initializes the repository. Without the timer installed you have no recurring backups,
+and `just watchdog <env>` reports exactly that.
+
+### Optional WebDAV offsite backups
+
+The supported offsite path is a second restic repository copied from the local restic repository.
+WebDAV is handled through restic's rclone backend.
+
+1. Create `secrets/<env>/rclone.conf` with a WebDAV remote.
+
+1. Set `RESTIC_OFFSITE_REPOSITORY` in `deploy/env/<env>.compose.env`, **not** the root `.env`:
+
+   ```ini
+   RESTIC_OFFSITE_REPOSITORY=rclone:relab-webdav:relab/staging/restic
+   ```
+
+   It belongs there because the root `.env` is shared by every stack on the host, so one value
+   would resolve to the same path for staging and production alike — writing production snapshots
+   into staging's offsite repository. The per-environment files are loaded second and override the
+   root `.env`, so a value set there is ignored.
+
+   Once set, the scheduled `backups` service copies snapshots offsite automatically at the end of
+   every backup cycle, initializing the offsite repository on first run. No further action is
+   needed for ongoing offsite copies.
+
+1. To copy snapshots on demand outside the scheduled cycle (for example, right after a one-off
+   local backup), export the same variable in the shell that runs the manual helper. The helper
+   reads exported variables; Docker Compose continues to read root `.env` through its normal
+   `--env-file` path.
+
+   ```sh
+   export RESTIC_OFFSITE_REPOSITORY=rclone:relab-webdav:relab/staging/restic
+   ```
+
+   ```bash
+   just backup-offsite-copy staging
+   ```
+
+### Optional: central telemetry
+
+If you run a central monitoring stack (Grafana + Loki + Tempo + Prometheus), prod and staging can
+ship to it without any code changes:
+
+1. Set `OTEL_EXPORTER_OTLP_ENDPOINT`, `OTLP_AUTH_TOKEN` and `TELEMETRY_EDGE_KEY` in the host's root
+   `.env`, from your monitoring stack operator (see `.env.example` for what each one is). That
+   single switch turns on both halves of telemetry: the backend's own OpenTelemetry exporter, and a
+   Grafana Alloy agent that collects every other container's stdout and forwards it over the same
+   OTLP endpoint.
+
+1. The `prod-up` / `staging-up` recipes auto-include `compose.telemetry.yml` when the endpoint
+   is non-empty. Hosts without it ship nothing and keep `docker logs` as the only log path.
+
+Alloy reads the Docker socket to attach container names to log lines, so it runs as root with the
+socket bound read-only. Note that a read-only bind protects the file, not the API — anything able to
+reach that socket can start a privileged container. If that is not acceptable on your host, put a
+docker-socket-proxy in front of it restricted to the container endpoints.
+
+See [Deployment and operations](/operations/deployment/#telemetry) for the full flow.
+
+## Raspberry Pi camera plugin
+
+If you want camera-assisted capture, see the external plugin repository:
+
+[Raspberry Pi Camera Plugin](https://github.com/CMLPlatform/relab-rpi-cam-plugin)
+
+The plugin uses a **WebSocket relay**: the RPi connects outbound to the backend, so no public IP or
+port forwarding is needed. The quickest setup is **automatic pairing**: set `PAIRING_BACKEND_URL` on
+the RPi, boot it, and enter the displayed pairing code in the app. See the
+[plugin install guide](https://github.com/CMLPlatform/relab-rpi-cam-plugin/blob/main/INSTALL.md),
+the [platform camera guide](/user-guides/rpi-cam/), and the
+[API reference overview](/api-reference/) for endpoint details. If the Pi is headless, you can read
+the pairing code either from its local `/setup` page or from the `PAIRING READY` log line over SSH,
+`docker compose logs`, or `journalctl`.

+title: Security and hardening
+description: Relab's deployed security posture and trust-boundary controls.
+---
+
+Relab is a self-hosted research platform. Its security posture is intentionally small and explicit: public traffic enters through Cloudflare Tunnel, data services stay on private Compose networks, outbound backend HTTP is allowlisted, and sensitive application behavior is covered by source-controlled checks.
+
+## Baseline
+
+Relab uses [OWASP ASVS](https://github.com/OWASP/ASVS) as the application-security baseline. The practical review focus is:
+
+- authentication, OAuth, and token flows
+- public read APIs and authenticated mutation APIs
+- uploads, media, malware scanning, and file storage
+- admin APIs
+- RPi camera device APIs and WebSocket relay
+- backups, secrets, logs, telemetry, and release/security artifacts
+
+Valuable assets include accounts, profile/privacy settings, research records, uploaded media/files, OAuth and YouTube tokens, RPi camera credentials, refresh-token state, database dumps, backup material, and runtime secrets.
+
+## Data protection
+
+Relab classifies data by how much harm disclosure or misuse would cause, then keeps the protection rules close to that classification:
+
+- **Public research data:** product records, public catalog/reference data, public dataset metadata, and intentionally public uploaded media. These may be cached when responses are public and content-addressed assets must 404 when missing rather than falling back to the app shell.
+- **Published dataset releases:** curated, versioned snapshots deposited under an open licence with a DOI. These are the one data class that cannot be recalled: a release is immutable and mirrored by third parties once published, so account deletion and upload deletion remove records from the live platform without retracting anything already released. Everything entering a release is therefore checked before deposit rather than protected after it — pseudonymised owner identity, named attribution only for contributors who opted in, and no account, auth, or contact data at any point.
+- **User and account data:** email addresses, usernames, profile preferences, contribution statistics, owner attribution, and account state. These are access-controlled by backend dependencies and privacy policy helpers. Viewer-dependent API responses use `no-store`, and product owner identity is redacted when profile visibility does not allow the current viewer to see it.
+- **Secrets and credentials:** passwords, auth tokens, refresh-token state, OAuth/YouTube tokens, RPi camera credentials, local camera API keys, runtime secrets, encryption keys, database passwords, and backup passwords. These must not appear in URLs, logs, browser local storage, docs examples, or analytics. Browser sessions use secure cookies; native bearer tokens use platform secure storage; local camera API keys use secure storage on native and memory-only storage on web.
+- **Uploads and metadata:** uploaded images, generic research files, derived thumbnails, image metadata, video metadata, and RPi capture metadata. Uploads are validated, malware-scanned when enabled, and size-limited before storage. Stored display images are post-processed to apply orientation and reduce EXIF metadata to an allowlist of capture parameters (camera and lens model, exposure, focal length, ISO, white balance) — GPS, vendor MakerNote blocks, serial numbers, and everything else identifying are dropped; original research files are stored as submitted because the file itself is the research artifact.
+- **Operational data:** request IDs, logs, telemetry, database dumps, and backup archives. Logs and traces must avoid tokens, passwords, OAuth material, private URLs, and sensitive personal values. Backups and dumps inherit the highest classification of their contents and are encrypted, access-controlled, and retained only for operational recovery.
+
+Protection requirements:
+
+- Send sensitive values in request bodies, headers, secure cookies, or URL fragments that are scrubbed by the client; never place them in server-visible query strings.
+- Use `Cache-Control: no-store` for authenticated, viewer-dependent, error, logout, password-reset, and verification flows. Public immutable assets may use long-lived caching only when missing files produce a real 404.
+- Keep access control server-side. Public docs schemas and filtered UI states are inventory tools, not authorization controls.
+- Store secret material in Docker secrets, secure platform stores, hashed/token-fingerprint state, or encrypted backup material as appropriate for the data type.
+- Delete obsolete runtime state through existing session revocation, upload deletion, cache invalidation, cleanup, and backup rotation workflows. Add explicit retention automation when a new data class needs a schedule beyond those workflows.
+
+## Account privileges
+
+Three independent account attributes decide what an account may do. Conflating any two of them is a privilege escalation, so each is enforced separately:
+
+- `is_verified` — whether the account may create records at all.
+- `is_superuser` — access to the `/admin` routes. It carries no data privileges: a superuser who is not `lab` is refused a research-file upload exactly like any other contributor.
+- `role` — the contributor tier, `contributor` (the default) or `lab`. It gates non-image research-file upload and selects the upload quota tier.
+
+Roles are set only by a superuser, through `PUT /v1/admin/users/{user_id}/role`, and every change is audit-logged. `role` is deliberately absent from the self-service update schema rather than filtered out of it, so a self-service `PATCH /users/me` has no field through which to reach it. New accounts, and every account backfilled when roles were introduced, start at `contributor`.
+
+Clients hide affordances the account's role cannot use — the app renders its research-file block for lab accounts only. That is presentation. The control is the route dependency, which refuses the request whatever the client chose to display.
+
+## Logging and error handling
+
+The backend writes application, access, audit, and security-control events through the standard Python logging stack. Development logs are human-readable; production and staging logs are JSON on stderr so container log drivers and processors can parse them consistently. Each request gets an `X-Request-ID` value that is echoed to the client and attached to backend log records with method, path, status, and latency.
+
+Structured audit events cover accountability actions and security-control outcomes such as login success or failure, MFA challenge success or failure, logout, all-session revocation, authorization denial, and rate limiting. Event fields are sanitized before logging. Logs may include stable IDs, masked account identifiers, request metadata, action names, resource labels, outcomes, and non-secret reasons; they must not include passwords, raw tokens, OAuth material, private URLs, or raw sensitive payload bodies.
+
+Container logs are the default storage and transport mechanism. Deploy hosts may enable OpenTelemetry export when an operator has a separate collector, which also starts an Alloy agent forwarding the other containers' stdout over the same authenticated OTLP endpoint. The sanitization guarantees above apply to the backend's own structured logging only: the other containers' stdout (PostgreSQL error logs in particular can quote statement text with literal parameter values) is shipped as-is, so the collector destination must sit inside the same data-protection boundary as the database — a department-operated stack, not an arbitrary third-party service. Log access, retention, backup, and deletion are operator responsibilities outside the application process; Relab only emits to the documented stdout/stderr or OTLP paths configured for that deployment.
+
+Unexpected application errors are handled by the backend catch-all exception handler. Internal details and stack traces are logged for operators, while clients receive generic Problem Details responses with the request ID for correlation.
+
+## Inbound edge
+
+Production and staging are HTTPS-only behind Cloudflare Tunnel. Source-controlled Cloudflare configuration owns the public edge: `infra/cloudflare/` holds the per-environment DNS records, public hostnames, and tunnel ingress rules, and `infra/cloudflare-zone/` holds the zone-wide TLS minimums, HTTPS redirects, and rulesets. Edge rate limiting covers the authentication endpoints only (the zone's plan allows a single rate-limit rule); upload and RPi camera limits are enforced in the application's Redis-backed limiters, which fail open when Redis is unreachable — during a Redis outage the per-user upload ledger is the remaining bound.
+
+Unknown tunnel hostnames fall through to a final `http_status:404` rule. Compose still owns runtime services; OpenTofu owns only the public edge.
+
+## Network boundaries
+
+The deploy stack keeps segmentation at Compose scale:
+
+- public-facing services use the `edge` network
+- PostgreSQL, Redis, migrations, and backups use the internal `data` network
+- ClamAV scanning uses the private `scanning` network
+- only the API bridges the networks it needs
+
+PostgreSQL and Redis do not publish host ports in prod or staging. The current internal-network defaults are `DATABASE_TLS=false` and `REDIS_TLS=false`. If either service moves to an external host, managed service, or other untrusted network, enable validating TLS with `DATABASE_TLS=true` or `REDIS_TLS=true`; set the matching CA file variable for private CAs.
+
+## Backend egress
+
+Backend outbound HTTP must use the shared HTTP client unless a reviewed exception exists. The shared client ignores ambient proxy and CA environment variables, does not follow redirects, uses bounded timeouts, validates TLS certificates, and permits only `OUTBOUND_HTTP_ALLOWED_URLS`.
+
+Prefer exact HTTPS URLs. Use trailing-slash prefixes only for integrations with required dynamic path segments. Keep GitHub, raw GitHub, and provider API access narrowed to the specific integration URLs Relab uses.
+
+## Denial-of-service controls
+
+Relab keeps denial-of-service mitigation layered. Cloudflare Tunnel is the public ingress for production and staging; source-controlled edge rules cover `/v1/auth/*`, upload routes, RPi camera upload routes, and WebSocket connection attempts. Volumetric attacks are handled by Cloudflare and upstream infrastructure, not by FastAPI.
+
+The expensive paths are media uploads, image processing and thumbnails, malware scanning, file cleanup, backups, OpenAPI/schema generation, YouTube API calls, and RPi camera relay/HLS traffic. The backend keeps these bounded with JSON streaming limits, multipart upload caps, file format allowlists, user upload quotas, Redis-backed route rate limits, image worker limits, ClamAV scan timeouts, bounded outbound HTTP timeouts/retries, WebSocket authentication and frame limits, and camera relay commands that fast-fail for cameras without a live heartbeat-maintained online status.
+
+Long-running maintenance work should stay in `just` tasks, scripts, migrations, or background services rather than request handlers. New API paths that can exceed normal client timeouts need asynchronous processing or explicit limits before exposure.
+
+For one host only, create a gitignored `compose.host.yaml`; deploy recipes include it last:
+
+```yaml
+services:
+  api:
+    environment:
+      WEB_CONCURRENCY: "1"
+```
+
+## Browser runtime policy
+
+Relab does not load third-party browser runtime JavaScript by default. Browser code is bundled and served first-party; Biome and CI checks block remote script tags, remote module imports, CDN runtime assets, analytics snippets, and tag-manager snippets.
+
+The current exception is product video embedding from `https://www.youtube-nocookie.com`, constrained by CSP and iframe/WebView controls. Any new third-party runtime script must be reviewed, documented, CSP-allowlisted, and tested.
+
+The Expo web app requires inline and eval-style first-party script support in the enforced CSP. A stricter report-only policy is active and documented as an ASVS V3 L3 exception. Docs and public web origins enforce stricter script policies; all browser origins enforce `object-src`, `base-uri`, `frame-ancestors`, and referrer suppression.
+
+## Supply chain
+
+GitHub Dependency Review and Dependency Graph gate dependency changes, while Renovate opens dependency update PRs. For an explicit full-tree dependency vulnerability sweep, run `just audit`.
+
+The security workflow builds deployable Compose images, scans them with Trivy, and stores SPDX JSON SBOM artifacts for 90 days. Release automation rebuilds deployable images, generates SPDX SBOMs, attests SBOM files with GitHub artifact attestations, and uploads them with GitHub releases.
+
+Dependency updates use risk-based timeframes:
+
+- critical exploitable vulnerabilities: mitigate or patch within 48 hours
+- high vulnerabilities: patch within 7 days
+- medium vulnerabilities: patch within 30 days
+- low vulnerabilities and routine library updates: handle in the normal weekly Renovate cycle
+
+If no upstream fix exists, record the accepted risk, compensating control, or temporary pin in the PR, issue, or nearest maintainer documentation. Do not keep production dependencies past these windows without an explicit maintainer decision.
+
+Trusted dependency sources are the source-controlled package manifests, lockfiles, Docker image references, GitHub Actions pins, and Renovate configuration. SBOMs produced by security and release workflows are the deployable dependency inventory. Relab deploys locally built Compose images, so release attestations prove SBOM file provenance; image-digest-bound SBOM attestations require publishing runtime images to a registry.
+
+Risky components are dependencies that parse untrusted content, execute native code, perform cryptography, manage authentication, or open network/file boundaries. Current examples include image processing, archive/office file inspection, OAuth/provider clients, S3-compatible storage, Redis/PostgreSQL drivers, ClamAV, and browser media playback helpers. Changes to these components need maintainer review even when automated checks pass.
+
+## Dangerous functionality
+
+Dangerous functionality is isolated behind small modules and reviewed as a security-sensitive bucket:
+
+- upload byte handling, public file serving, image processing, archive/office inspection, and malware scanning live in the backend file-storage and image modules
+- outbound HTTP must use the shared client with no ambient proxy trust, no automatic redirects, bounded timeouts, TLS validation, and URL allowlists
+- RPi camera direct and relayed traffic is authenticated, rate-limited, and separated from database/storage services by Compose network boundaries
+- backup jobs read database and upload volumes but run in dedicated containers with separate secrets

+title: The 9R framework
+description: The ten circularity strategies, R0 to R9, that frame what Relab records during disassembly.
+---
+
+import NineRLadder from '@/components/NineRLadder.astro';
+
+Relab is built around the 9R framework: ten circularity strategies, R0 to R9,
+ordered from smartest to last resort. The higher a product stays on the
+ladder, the more of its value survives.
+
+<NineRLadder />
+
+The tables below give each strategy's definition. They are the source of record
+for the wording; the ladder above shows only the order.
+
+## Smarter product use and manufacture
+
+| #   | Strategy | Definition                                                                                                          |
+| --- | -------- | ------------------------------------------------------------------------------------------------------------------- |
+| R0  | Refuse   | Make product redundant by abandoning its function or offering the same function with a radically different product. |
+| R1  | Rethink  | Make product use more intensive (e.g. sharing, or multi-functional products).                                       |
+| R2  | Reduce   | Increase efficiency in manufacture or use by consuming fewer resources and materials.                               |

+| --- | ------------- | --------------------------------------------------------------------------------------------------------------- |
+| R3  | Re-use        | Re-use by another consumer of a discarded product still in good condition and fulfilling its original function. |
+| R4  | Repair        | Repair and maintenance of a defective product so it can be used with its original function.                     |
+| R5  | Refurbish     | Restore an old product and bring it up to date.                                                                 |
+| R6  | Remanufacture | Use parts of a discarded product in a new product with the same function.                                       |
+| R7  | Repurpose     | Use a discarded product or its parts in a new product with a different function.                                |

+| --- | -------- | ------------------------------------------------------------------------------- |
+| R8  | Recycle  | Process materials to obtain the same (high-grade) or lower (low-grade) quality. |

+title: Dataset codebook
+description: Every column in a Relab dataset release, with its type and meaning.
+---
+
+import Codebook from '@/components/datamodel/codebook.generated.mdx';
+
+A published [dataset release](/project/dataset/) ships as a set of Parquet files. This page
+documents every column in them: what it holds, what its absence means, and how far to trust it.
+
+The tables come from the release schemas in `backend/scripts/build_dataset_release.py`, so they
+describe the archive the build produces rather than the platform's internal database. For that
+database, see [Data model](/architecture/datamodel/).
+
+Every release also carries `croissant.json`, which repeats these descriptions in
+[MLCommons Croissant](https://mlcommons.org/working-groups/data/croissant/) form for tools that
+read dataset metadata directly.
+
+## How to read the tables
+
+- **Required** means the column is never null. Everything else can be null, and null means
+  "not recorded" rather than zero or empty. A missing `weight_g` is a product nobody weighed,
+  not a weightless product.
+- Identifiers are unique within one release, and reference tables are joined by them.
+- `records.parquet` holds both whole products and their components in one table. A row with a
+  null `parent_id` is a whole product; anything else is a part taken out of the row named by
+  `parent_id`. Depth is not bounded, so treat it as a tree, not two levels.
+- Reference tables under `reference/` are frozen copies taken at build time. They are the
+  vocabulary the records were annotated against, not a live taxonomy.
+
+## Contributor identity
+
+`owner_pseudonym` is the only trace of who recorded a row. It is a salted hash, and the salt
+stays unpublished. Each release credits its contributors collectively in its `README.md`
+rather than naming them against their rows.
+
+The same contributor keeps the same pseudonym from one release to the next, which is what makes
+longitudinal work possible. That holds only across releases built with the same salt. Each
+release publishes a pseudonym salt fingerprint in its `README.md`: two releases whose
+fingerprints match have comparable pseudonyms, and two that differ do not. Check the
+fingerprint before you join on `owner_pseudonym` across releases.
+
+Re-identifying contributors falls outside the licence, and outside the GDPR basis the release
+was published under.

-
-The dataset layer is where live RELab records become a citable research output: a curated, versioned snapshot with explicit provenance, scope, and licensing, decoupled from the operational database. Keeping that boundary sharp is what makes the data reusable beyond the project — for benchmarking, comparative studies, and integration with other industrial-ecology infrastructures.

-## Access and Publication Status
+## Access
 
-The intention is to publish the dataset openly. The publication workflow is still maturing, so the most reliable technical interface right now is the live API rather than a formal release portal.
+Current records can be explored in the app or through the API. For technical access, see the
+[API reference overview](/api-reference/) or go directly to the
+[public API reference](/api/public/).
 
-[API Access](https://api.cml-relab.org/docs)
+Curated releases will have a defined scope, version, and license, so they can be cited and linked
+with other open industrial-ecology datasets. The planned license is
+[CC BY 4.0](https://creativecommons.org/licenses/by/4.0/). No release has been published yet.
 
-A browsable dataset portal and curated downloadable releases are planned.
+The [dataset codebook](/project/codebook/) documents every file and column a release carries, so
+the shape of one can be read before the first release exists.
 
-In the broader project vision, dataset publication is not only an output step. It is also part of building an open industrial ecology data commons that others can inspect, reuse, compare, and extend.

+## Building and depositing a release
+
+(For maintainers.) The build and deposit pipeline lives in `backend/scripts/` and runs from
+`backend/`:
+
+1. `just release-build --inventory` — a dry run across every consenting account: writes nothing,
+   just reports what a release would contain. "Consenting" means the owner accepted the
+   contributor terms at the version that grants the publication licence; everyone else is
+   excluded by the `no-terms-acceptance` rule and appears in `excluded-records.csv`.
+   Accounts created before acceptance was tracked hold no grant until they answer the in-app
+   prompt, so the consenting set grows as contributors sign in. Declining is free and costs a
+   contributor nothing except inclusion, so expect it to be a real outcome rather than a
+   formality.
+1. `just release-build --out dist/dataset-vX.Y` — builds the release directory. The verification
+   pass at the end is not optional; it fails the build rather than warning.
+1. Review `dist/dataset-vX.Y/review/` by hand, including `excluded-records.csv` and the rule that
+   excluded each record. This directory is not part of the published archive.
+1. The pseudonymisation salt comes from `RELAB_PSEUDONYM_SALT` (preferred), `--pseudonym-salt`, or
+   `secrets/<env>/dataset_pseudonym_salt`; keep the same salt for every future release so owner
+   pseudonyms stay stable across versions.
+1. `uv run python -m scripts.zenodo_deposit --dir dist/dataset-vX.Y` creates or versions a Zenodo
+   *draft*. Add `--deposition <id>` to resume uploading into an existing draft rather than starting
+   a new one. The token is read from `secrets/<env>/zenodo_token` (or `ZENODO_TOKEN` for a one-off
+   run).
+1. Inspect the draft in the Zenodo web UI, then publish explicitly with
+   `--deposition <id> --publish`. Publication is irreversible — a published record can be
+   tombstoned but never withdrawn or edited — so this prompts before it sends anything.
+
+Full flags: `just release-build --help` and `uv run python -m scripts.zenodo_deposit --help`.

-Why RELab exists, what it is for, and where it is going. The short version: a bottom-up platform for generating, sharing, and reusing product data for industrial ecology and circular economy research.
-</div>
+Relab exists to make product disassembly data easier to collect and reuse. These pages explain the
+research framing, current priorities, and the path from live records to curated dataset releases.
 
-<div class="grid cards relab-card-grid" markdown>
+## Why Relab exists
 
-- **[Use Cases](use-cases/)**
-  What the platform is for in practice, and why bottom-up data generation matters.
+Circular-economy and industrial-ecology research depends on detailed product data: what things are
+made of, how they come apart, and what evidence backs those claims. Without it, life-cycle
+assessment and material flow analysis cannot quantify environmental impacts, identify recovery
+pathways, or inform circular design. That data is scarce, mostly closed, and slow to produce.
+Producers tend to hold it as proprietary, and small expert teams sampling products by hand cannot
+keep pace with everything entering the market. The scale of the shortfall is easy to state: the
+Global LCA Data Access network hosted roughly 130,000 process datasets as of 2024, against millions
+of consumer products on the market.
 
-- **[Roadmap](roadmap/)**
-  Near-term and longer-term priorities.
+Relab works downstream instead, with the people who already open products: repairers, refurbishers,
+dismantlers, recyclers. They meet products at the point of failure, which shows as-failed
+composition, wear, and recoverability that as-designed specifications never record. Low-barrier
+tools turn that routine work into structured, openly licensed observations.
 
-- **[Dataset](dataset/)**
-  Publication goals, metadata, licensing, and the path from operational data to research output.
+Some of that work is already recorded. Under the Open Repair Data Standard, repair groups have
+logged more than 400,000 repair records covering product category, brand, age, fault, and outcome.
+Those records are event-level: they carry no component hierarchies, no masses, no geometry. Relab's
+contribution is that missing depth, at the component level, together with standardized imagery.
 
-</div>
+The exchange is meant to run both ways. A circular economy for products needs a *circular data
+economy* alongside it: one that feeds middle- and end-of-life observations back into the data
+infrastructure that research and design draw on, rather than letting product information stop at the
+point of sale. Closing that loop means returning value to contributors, and the architecture is
+built for it: composition insight and sustainability metrics delivered back to the people who record
+the products. That return is a design goal rather than a shipped feature, and whether it is enough
+to sustain contribution is untested.
+
+## What has been demonstrated
+
+A pilot evaluated the platform on 78 small durable consumer products: 46 documented in a controlled
+laboratory, and 32 at two workshops by 135 participants, mostly LCA practitioners and researchers.
+It produced 1,331 component records and 3,610 images. Laboratory records were substantially deeper
+than workshop ones, which were structured but shallower.
+
+These are pilot figures, not the size of the live dataset, which grows as records are added; see
+[Dataset](dataset/) for what is in the app today. Two limits are worth stating plainly. Deployment
+with repair, dismantling, and recycling practitioners is untested future work. And interoperability
+across taxonomies and external tools is a design goal rather than demonstrated functionality.
+
+## Where to go next
+
+[Use cases](use-cases/) is the most useful page if you are deciding whether Relab fits your work,
+since it is explicit about what the platform deliberately does not try to be. [The 9R
+framework](9r-framework/) is background: the ten circularity strategies, R0 to R9, that the project
+takes its cue from and that the mark's nine nods to, rather than anything the platform applies to a
+record. [Dataset](dataset/) covers how to browse current records and how curated releases will
+differ from the live app. [Roadmap](roadmap/) tracks current priorities, with GitHub issues as the
+live work list.

+title: Licensing
+description: How Relab licenses its software, its API specification, and its dataset releases, and the two limits no licence changes.
+---
+
+Relab licenses four layers separately, on purpose. Which one applies depends on what you are
+reusing, not on which repository you found it in.
+
+| Layer                                                                                    | Licence                                                                         |
+| ---------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------- |
+| Platform software: the code behind the backend, app, website, and this docs site         | [AGPL-3.0-or-later](https://github.com/CMLPlatform/relab/blob/main/LICENSE)     |
+| API specification: the OpenAPI schemas this repository generates, and their client types | [Apache-2.0](https://github.com/CMLPlatform/relab/blob/main/LICENSE-APACHE-2.0) |
+| Site content: the writing on the docs site and on [cml-relab.org](https://cml-relab.org) | [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/)                       |
+| Curated dataset releases                                                                 | [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/), planned              |
+
+Code samples inside the documentation are **Apache-2.0**, not CC BY, so that copying one into your
+own project raises no question — it lands under the same terms as a generated client. And whatever
+the layer, the Relab name, logo, and wordmark are **not licensed**; see
+[Names and marks](#names-and-marks) below.
+
+## Why the API specification is carved out
+
+The platform is copyleft, including over a network, so a hosted fork stays open. Applying that to
+the integration surface would work against the point of publishing one: anyone writing a client, an
+importer, or a pipeline against the API would inherit obligations from a file that only describes an
+interface. An interface description is thin copyright in any case, since
+[Directive 2009/24/EC art. 1(2)](https://eur-lex.europa.eu/eli/dir/2009/24/oj) excludes the ideas
+and principles underlying a program's interfaces from protection.
+
+Apache-2.0 rather than a public-domain dedication, because the carve-out covers generated TypeScript
+client types as well as the schemas. Those are software, which Creative Commons advises against
+covering with a CC licence, and Apache-2.0 carries an explicit patent grant.
+
+In practice: **generate a client from the public or device schema and you inherit no copyleft.**
+
+The carve-out covers the two schemas this repository generates, `openapi.public.json` and
+`openapi.device.json`. The [RPi camera API](/api/rpi-cam/) is not one of them:
+`openapi.rpi-cam.json` is fetched verbatim from the separate
+[relab-rpi-cam-plugin](https://github.com/CMLPlatform/relab-rpi-cam-plugin) repository and carries
+whatever licence that project sets — currently Apache-2.0 as well, so in practice all three
+published schemas answer alike. Check there before reusing it, since that project decides.
+
+## Dataset releases
+
+Curated releases are planned under CC BY 4.0. No release has been published yet, so nothing is
+distributed under those terms today; see [Dataset](/project/dataset/) for what a release will
+contain and how it differs from the live records in the app.
+
+CC 4.0 licenses the EU *sui generis* database right alongside copyright, so one instrument covers
+both the structure of the database and its contents, and no second licence is needed for the records
+themselves. Attribution is the whole obligation, which is what keeps a release usable for
+machine-learning work.
+
+## Site content
+
+The writing on this docs site and on the main site — pages, guides, explanations, diagrams — is
+CC BY 4.0. Quote it, translate it, teach from it, adapt it; credit Relab and say if you changed it.
+
+Applying the platform's copyleft to prose would have been an odd fit: its obligations are about
+providing corresponding *source*, which means nothing for a paragraph. Attribution is the obligation
+that actually expresses what the project wants from a reader.
+
+The exception is **code samples**, which are Apache-2.0. Creative Commons advises against covering
+software with a CC licence, and someone pasting a snippet from a guide into their own project should
+not have to reason about attribution terms written for prose. Samples land under the same licence as
+a client generated from the API specification.
+
+## Names and marks
+
+**Relab, the logo, and the wordmark are not covered by any licence on this page.** No licence
+here — not AGPL, not Apache-2.0, not CC BY — grants rights in them, and CC BY says so explicitly
+([§2(b)(2)](https://creativecommons.org/licenses/by/4.0/legalcode#s2b)).
+
+This is worth stating rather than leaving to inference, because the rest of the project is open
+enough that a reader could reasonably assume the marks come along with it. They do not. Reuse the
+software, the specification, the writing, and the data freely; use the name and the mark only to
+refer to this project, not to identify your own work as Relab or to imply endorsement.
+
+Nominative use — naming Relab as a source, citing it, writing about it, showing a screenshot in a
+paper or a talk — needs no permission and is what the licences above are for.
+
+## Two limits no licence changes
+
+**Personal data is governed by the GDPR regardless of the licence.** A licence grants permissions
+over material the licensor may lawfully distribute; it cannot make publication of personal data
+lawful. What makes a release publishable is the sanitisation applied when building it, described in
+[Security and hardening](/operations/security/), not the CC BY grant on top.
+
+**CC BY grants no trademark rights**
+([CC BY 4.0 §2(b)(2)](https://creativecommons.org/licenses/by/4.0/legalcode#s2b)). Teardown
+photographs necessarily show brand marks and model numbers. The licence covers those images as
+images; it licenses nothing about the marks in them.

+description: Research and platform priorities for the next Relab phases.
 ---
 
-This roadmap reflects research priorities, not a generic product backlog.
+Reviewed: 2026-08
 
-## Research Direction
+## Research direction
 
 The main question is how to make product data collection more scalable, collaborative, and reusable.
+Relab focuses on open, FAIR product-level disassembly data. Automation stays
+human-verified: software can suggest, people confirm.
 
-A second question is where AI methods can help with collection, validation, normalization, and linking.
+The live work list is tracked in the public
+[GitHub issues](https://github.com/CMLPlatform/relab/issues).
 
-Interoperability is part of the roadmap too: keep identifiers, APIs, and dataset exports simple enough to support later reuse and linking.
+## Near term
 
-## Short Term
-
-- [ ] improve the user-facing documentation of the data collection workflow
-- [ ] keep the docs site aligned with the codebase as the platform changes
-- [ ] continue strengthening unit and integration test coverage in areas that already exist
-- [ ] make operational procedures such as backup, restore, and deployment more explicit
-- [ ] make the path from live records to dataset release clearer
-
-## Medium Term
-
-- [ ] stabilize a dataset publication workflow separate from the live application database
-- [ ] make that publication workflow suitable for stable public release
-- [ ] support later reuse through stable identifiers, APIs, and dataset exports
-- [ ] improve admin and background-data maintenance workflows
+- [ ] improve the data collection guides and keep the rest of the docs current
+- [ ] strengthen tests, especially around component hierarchies
+- [ ] simplify CSV and JSON export from live records toward dataset releases
+- [ ] improve admin and reference-data maintenance workflows
 - [ ] make camera-assisted capture easier to operate in repeated lab workflows
-- [ ] improve API guidance for external analysis scripts and reproducible exports
-- [ ] explore assistance features for AI-supported collection and validation workflows
-
-## Longer Term
-
-- [ ] support more formal dataset versioning and release documentation
-- [ ] add better support for downstream computational analysis and model-building workflows
-- [ ] evaluate whether more automation is useful for annotation, quality control, or media processing
-- [ ] refine the public-facing presentation of the project as the research output matures
 
-## Constraints That Shape The Roadmap
+## Later
 
-- the platform is developed in the context of a PhD project, so maintainability matters more than rapid feature expansion
-- research needs may change as data collection progresses
-- infrastructure and operations should stay proportional to the size of the project
-- some roadmap items depend on decisions about publication, collaboration, and dataset governance that are partly non-technical
+- [ ] publish curated, versioned dataset releases separate from the live database, with stable
+  identifiers and documented scope and licensing
+- [ ] improve API guidance and exports for analysis scripts, reproducible research, and LCA work
+- [ ] explore human-verified assistance for label reading, component suggestion, and quality
+  control, with provenance records for assisted values
+- [ ] explore interoperability with semantic vocabularies and Digital Product Passport identifiers

-## Primary Research Use Case
+## What Relab is for
 
-RELab collects product data through disassembly records with media. Middle- and end-of-life actors can add observations directly.
+Relab is for documenting real products as they are taken apart. It keeps product identity, component hierarchy, photos, measurements, material notes, and uncertainty in one record.
 
-It keeps item identity, component hierarchy, media, and material notes.
+The main use case is research data collection for durable goods: enough structure for later comparison, but still practical for a lab bench or repair workspace.
 
-Typical contributors:
+Typical contributors include:
 
 - repairers and refurbishers
 - manual dismantlers and recyclers
 - researchers and lab assistants
 - citizen scientists
 
-## Non-Goals
+## What Relab is not
 
-RELab is not:
+Relab is not:
 
 - a general-purpose product lifecycle management system
 - a mass-scale crowdsourcing platform
 - a fully automated computer-vision pipeline
 - a highly elastic cloud-native platform
 
-The scope stays narrow because the research questions drive what gets built.
+Keeping the scope narrow keeps the platform simple enough for a small research team to run, and for new contributors to learn quickly.

+For the authoritative schemas, request models, and endpoint lists, start from the
+[API reference overview](/api-reference/). For how the API is designed internally, see

-## When to Use the API Directly
+The public API is versioned under `/v1`. Keep the API origin separate from the versioned path in
+your client configuration, then build requests such as `https://api.cml-relab.org/v1/products`.
+
+## When to use the API directly
 
 - scripted or batch access to structured research data
-- connecting RELab records to notebooks or external tooling
+- connecting Relab records to notebooks or external tooling
 - automating repetitive reference-data lookups
 - building custom integrations on top of the platform
 
 ## Authentication
 
-- **Browsers** use cookies (`POST /auth/cookie/login`)
-- **Apps and scripts** use bearer tokens (`POST /auth/bearer/login`)
-- Refresh-token handling depends on the Redis-backed auth path (see [Authentication](../../architecture/auth/))
+- Browsers use cookies (`POST /v1/auth/session/login`)

+- Refresh-token handling depends on the Redis-backed auth path (see
+  [Authentication](../../architecture/auth/))
 
-!!! note "Public vs. authenticated routes"
-Public reference data (taxonomies, materials, product types) is accessible without authentication. Product records, images, and user data require a valid token.
+:::note[Public vs. authenticated routes]
+Public reference data (taxonomies, materials, product types), product records, and uploaded media
+are accessible without authentication. Creating or changing records, account management, private
+user details, and owner-scoped workflows require a valid token.
+:::
 
-## Suggested First Steps
+## Suggested first steps
 
-1. Open the [live OpenAPI docs](https://api.cml-relab.org/docs).
+1. Open the [API reference overview](/api-reference/) and choose the surface you need.
 1. Identify whether the endpoint you need is public or requires authentication.
 1. Start with a read-only request before attempting writes.
 1. Inspect response models carefully, especially around linked entities and media.
 1. Only automate writes once you understand how the product hierarchy is represented.
 
-## Integration Advice
+## Interactive tooling and admin tasks
+
+Point a client at the API and authenticate with a bearer token from `POST /v1/auth/bearer/login`.
+The same path covers superuser tasks like `POST /v1/admin/cache/clear/{namespace}`.
+
+- **Postman, Bruno, Insomnia**: import the OpenAPI schema (`app/src/types/openapi.json`) for the
+  full endpoint collection, then set auth to *Bearer*.
+- **VS Code REST Client / JetBrains HTTP Client**: use `scripts/admin.http` from a repo checkout —
+  send `login` once and the token flows into the calls below it.
+
+## Integration advice
 
-- Build against the live OpenAPI schema rather than copying examples from old documentation.
-- Treat uploads and image handling as first-class API operations, not afterthoughts.
-- If you need a stable exported dataset rather than live application access, check the [Dataset Documentation](../../project/dataset/) first.
+- Build against the generated OpenAPI schema rather than copied examples, which can drift out of
+  date.
+- For product circularity notes, use `circularity_properties` as either `null` or an object with
+  optional `recyclability`, `disassemblability`, and `remanufacturability` strings. Empty objects
+  and empty note strings are normalized to `null`.
+- If you need a stable exported dataset rather than live application access, check the
+  [dataset page](../../project/dataset/) first.

-## Reference Data
+## Measurements
 
-Use materials, categories, taxonomies, and product types when they improve consistency. Do not force a taxonomy entry when the evidence is weak; a missing link is clearer than a wrong one.
+Physical properties are the item's overall size in centimetres (width, height, depth as it sits in
+front of you) and its mass in grams. Enter what you measured; leave a field empty rather than
+typing `0`, because an empty field means "not recorded" and a zero means a weightless or flat
+object. Sub-gram masses (screws, clips) are fine as decimals.
 
-## Media Capture
+The circularity notes ask for three observations. *Disassemblability* means how easily the item
+comes apart into its parts and whether doing so damages them — tools needed, glued or welded
+joins, and anything you had to break count. *Recyclability* and *remanufacturability* are the same
+kind of observation about the materials and the reusable assemblies. Uncertain notes are welcome;
+see the box above.
+
+Every other term Relab uses is defined in the [Glossary](../glossary/).
+
+## Reference data
+
+Use materials, categories, taxonomies, and product types when they improve consistency. If no entry
+fits, leave the field empty rather than picking the closest match.
+
+## Media capture
 
 Attach media in two ways:
 
 - manual upload of files and images
 - device-assisted capture through the Raspberry Pi camera integration
 
-If you are using the camera integration, see [RPI Camera Integration](../rpi-cam/).
+Use image uploads for ordinary display photos. Use file uploads for research documents and
+scientific datasets, including hyperspectral ENVI, HDF5, NITF, and GeoTIFF files, so Relab stores
+the original data without image processing.
+
+Research-file upload is limited to lab accounts. Every signed-in, verified account can upload
+images; only a lab account sees the "Research files" block on a record it owns. Ask an
+administrator if you need the lab role.
+
+If you are using the camera integration, see [RPi camera integration](../rpi-cam/).
+
+## Upload limits
+
+Accepted types and size limits:
+
+- Images: `.bmp`, `.gif`, `.jpeg`, `.jpg`, `.png`, `.webp` — up to 10 MiB.
+- Research files: `.csv`, `.docx`, `.json`, `.md`, `.pdf`, `.pptx`, `.tsv`, `.txt`, `.xlsx` — up to
+  50 MiB.
+- Scientific data: `.dat`, `.h5`, `.hdr`, `.hdf5`, `.img`, `.nitf`, `.ntf`, `.raw`, `.tif`, `.tiff`
+  — up to 50 MiB.
+
+Relab validates type, size, and content before storing a file. It also unpacks and inspects office
+files before accepting them. If malware scanning is enabled, Relab scans files on upload and
+rejects flagged ones.
+
+Each account also has a cap on total file count and storage used, set by its role:
+
+| Role          | Files  | Storage  |
+| ------------- | ------ | -------- |
+| `contributor` | 1000   | 1024 MB  |
+| `lab`         | 20 000 | 20480 MB |
+
+Both tiers are tunable per instance by the operator through `MAX_UPLOAD_FILES_PER_USER` and
+`MAX_UPLOAD_BYTES_PER_USER_MB` for contributors, and `MAX_UPLOAD_FILES_PER_LAB_USER` and
+`MAX_UPLOAD_BYTES_PER_LAB_USER_MB` for lab accounts. An upload over either cap is rejected;
+deleting media releases the quota it used.
 
-## Final Check
+## Final check
 
 - Verify component-parent relations are correct.
 - Make sure important images are attached to the right record.
 - Add missing notes while the work is still fresh.
 - Normalize product types or materials where possible.
-- Leave uncertainty explicit rather than silently resolving it.
+- Keep "unconfirmed" notes as they are. Do not replace them with guesses.

-RELab is a platform for documenting product disassembly. You create structured records of what a product is made of, how it comes apart, and what the components look like.
+Relab helps you document a product while you take it apart. A useful first record does not need to be perfect; it needs a clear product identity, a few good photos, and notes on what you found.
 
-Those records are not just for private note-taking. The broader goal is that they can later be shared, compared, and reused as part of a larger open product-data infrastructure.

+title: Glossary
+description: What the words in Relab mean, in plain language.
+---
+
+Relab borrows its vocabulary from circular-economy research. Each term below is defined in
+ordinary words, with what Relab expects you to put in the field that carries it.
+
+You do not need to learn any of this before you start. Every field that uses one of these terms
+carries a short version of the same explanation next to it.
+
+## Records
+
+### Record
+
+One entry in Relab. A record is either a whole product or one component taken out of another
+record. Both hold the same fields.
+
+### Product
+
+The whole item you started with, such as a cordless drill. A product is the top of a record
+tree: it has no parent.
+
+### Component
+
+A part taken out of a product, such as a battery pack or a motor. A component is a record
+with a parent, and it can hold components of its own. The tree has no depth limit.
+
+Create a component when the part is worth its own photos and notes. See
+[When to create a child component](/user-guides/data-collection/#when-to-create-a-child-component)
+for where to draw the line.
+
+### Teardown
+
+One session in which somebody takes a product apart and records what they find. A finished
+teardown is a product record with its components under it.
+
+### Amount
+
+How many of a component the parent contains. Four identical screws in one housing are one
+component record with an amount of 4, not four records.
+
+## Measurements
+
+### Physical properties
+
+The item's size and weight, measured as it sits in front of you. Width, height, and depth are
+in centimetres; weight is in grams. Record a sub-gram weight, such as a clip, as a decimal.
+
+Leave a field empty if you did not measure it. An empty field means "not recorded". Do not type
+`0` instead: Relab rejects it, because a zero claims the object really is flat or weightless.
+
+### Circularity
+
+How well a product's materials and parts can be recovered and used again once it reaches the
+end of its life. The three circularity notes record it.
+
+### Circularity notes
+
+Three free-text observations you can add to any record. Write what you saw. An uncertain note is
+more useful than a confident guess. If you have neither, leave the note empty.
+
+### Recyclability
+
+What the parts are made of, and whether those materials can be separated and recovered.
+
+Example: "Housing likely polypropylene, unconfirmed — no resin code moulded in."
+
+### Disassemblability
+
+How easily the product comes apart into its parts, and whether that damages them. Tools
+needed, glued or welded joins, and anything you had to break all count.
+
+Example: "Opens with 6 Torx T10; battery is glued, had to be prised."
+
+### Remanufacturability
+
+Whether whole parts could be cleaned up and used again in another product.
+
+Example: "Motor and gearbox look reusable; control board is potted."
+
+## Reference data
+
+The shared lists you pick from: materials, categories, taxonomies, and product types. They exist so that two people describing the same thing use the
+same words.
+
+If no entry fits, leave the field empty. Do not pick the closest match.
+
+### Product type
+
+What kind of thing the item is, picked from a shared list rather than typed. Most entries come
+from CPV.
+
+### CPV
+
+Common Procurement Vocabulary, a standard European list of product categories. Relab uses it so
+that researchers can compare and count records across teardowns. You browse it by category and
+pick the closest match. The code itself never appears in the app.
+
+### Category
+
+A branch of the product-type list, such as tools or furniture. Categories group product types.
+They are not a separate label on your record.
+
+### Taxonomy
+
+One named classification scheme. CPV is a taxonomy. Relab can hold more than one.
+
+### Material
+
+What a part is made of, picked from a shared list. Attach a material to the record it describes,
+which is usually a component rather than the whole product.
+
+## The project
+
+### 9R framework
+
+Nine strategies for keeping products and materials in use, from refusing a product outright to
+recovering its energy. They motivate the project and give the wordmark its nine.
+
+Relab does **not** tag your records with an R-strategy. See
+[The 9R framework](/project/9r-framework/) for the strategies themselves.
+
+### Dataset release
+
+A published snapshot of Relab's records, as files anybody can download and cite. Contributors
+are credited collectively, not against individual rows. See
+[Dataset](/project/dataset/) and the [Dataset codebook](/project/codebook/).
+
+## Media and devices
+
+### Media
+
+Photos, videos, and files attached to a record. Photos often carry more evidence than the form
+fields, so attach anything a later reader might want to check.
+
+### Research file
+
+A non-image file attached to a record, such as a spreadsheet or a measurement dataset. Relab
+stores these unchanged, without image processing.
+
+### RPi camera
+
+An optional Raspberry Pi camera rig that sends photos straight into a record. You set it up once
+per camera, and the integration stays off until you turn it on. See
+[RPi camera integration](/user-guides/rpi-cam/).
+
+### Pairing code
+
+A six-character code the Raspberry Pi shows on its setup page or in its startup logs. Enter it
+in Relab once to connect that camera to your account.
+
+## Accounts
+
+### Verified
+
+An account whose email address has been confirmed. You can browse Relab without an account, and
+you can sign in without verifying. You need a verified email address to create records.
+

+ * scale DOWN to fit: measured on /architecture/system-design/ at 1440px, a
+ * 1636px diagram rendered at 758px (0.46x), putting 16px labels on screen at
+ * ~7.4px, and ~3px at 390px.
+ *
+ * Setting the explicit pixel width lets it overflow into the frame's existing
+ * `overflow-x: auto`, so labels stay at their authored size and the reader
+ * scrolls instead of squinting. Narrow diagrams are left alone: pinning one

-# Architecture
-
-High-level map of `frontend-app`. Links into the code rather than duplicating it —
-prefer reading the source of truth over this document when they disagree.
-
-## Stack
-
-- **Runtime:** Expo SDK 55, React 19, React Native 0.83, React Native Web.
-- **Routing:** [Expo Router](https://docs.expo.dev/router/introduction/) (file-based, typed routes).
-- **Data fetching:** [TanStack Query](https://tanstack.com/query) against a
-  FastAPI backend. Types are generated from the backend's OpenAPI schema.
-- **Client state:** [Zustand](https://zustand-demo.pmnd.rs/) stores, scoped per
-  feature.
-- **Forms:** React Hook Form + Zod resolvers.
-- **UI kit:** React Native Paper (Material 3 theming).
-- **Compiler:** React Compiler enabled via `babel-plugin-react-compiler`.
-
-## Source layout
-
-```
-src/
-├── app/              # Expo Router tree — one file per route.
-├── components/       # Feature folders (auth, cameras, product, profile, common, base).
-├── hooks/            # Cross-feature custom hooks.
-├── services/         # Backend integration: api/, media/, storage, domain stores.
-├── context/          # React context providers (auth session, theme, etc.).
-├── types/            # Hand-written types + api.generated.ts (do not edit).
-├── constants/        # Static values (routes, colors, env-derived constants).
-├── utils/            # Pure helpers, no React.
-├── test-utils/       # Shared test fixtures, MSW handlers, render helpers.
-├── assets/           # Fonts, images, icons.
-└── public/           # Files copied verbatim into the web export.
-```
-
-`base/` components are generic primitives; `common/` are app-wide composites;
-the rest are domain-scoped. Keep imports flowing inward (features may use
-`base`/`common`, not the reverse).
-
-## Routing
-
-`src/app/` is the Expo Router tree. Groups in parens (`(auth)`) don't affect
-the URL. Layouts (`_layout.tsx`) wrap their siblings. Typed routes are on, so
-links are type-checked against the file tree. Routes for auth, cameras,
-products, profile, users live directly under `src/app/`.
-
-## Data flow
-
-1. Backend exposes OpenAPI at `$EXPO_PUBLIC_API_URL/openapi_full.json`.
-1. `just codegen` regenerates [src/types/api.generated.ts](src/types/api.generated.ts)
-   and runs `scripts/redact_api.js` to strip JWT examples before commit.
-1. Request helpers live in [src/services/api](src/services/api); feature hooks
-   wrap them with TanStack Query, returning typed data.
-1. MSW handlers in `src/test-utils/` mock the same surface in unit/integration
-   tests so component code is identical in prod and test.
-
-Client-only state (wizard progress, transient UI) lives in Zustand stores
-co-located with the feature (e.g. `services/newProductStore.ts`). Server state
-stays in TanStack Query — don't mirror it into Zustand.
-
-## Testing layers
-
-| Layer       | Tool             | Location                          | What it covers                                                    |
-| ----------- | ---------------- | --------------------------------- | ----------------------------------------------------------------- |
-| Unit        | Jest + jest-expo | `src/**/*.test.ts(x)`             | Pure logic, single component, MSW-mocked.                         |
-| Integration | Jest + jest-expo | `src/**/*.integration.test.ts(x)` | Multiple components wired together, realistic nav.                |
-| E2E         | Playwright       | `e2e/`                            | Full-stack against the built web export + docker-compose backend. |
-
-Run via `just test-unit`, `just test-integration`, `just test-e2e`. See
-[README.md](README.md) for profiling tips.
-
-## Build & deploy
-
-- **Dev (web):** `just dev` — Expo Metro on :8081.
-- **Dev (native):** `pnpm android` / `pnpm ios`.
-- **Web build:** `just build-web` runs `expo export -p web -c` → `dist/`.
-- **Runtime:** Caddy serves `dist/` with CSP templated from
-  `CSP_API_ORIGIN`. See [Dockerfile](Dockerfile) and [Caddyfile](Caddyfile).
-- **Native releases:** not containerised; use Expo's native build flow from a
-  developer machine.
-
-## Linting ownership
-
-Biome is primary (formatting + most correctness). ESLint runs a narrow config
-for rules Biome doesn't yet expose (`react-hooks/*`, `react-refresh`). This is
-intentional overlap — see the "Lint Ownership" section of
-[README.md](README.md). When Biome ships the hooks/refresh rules, remove
-ESLint and its plugins.

-# RELab App
-
-The `frontend-app` subrepo contains the Expo / React Native app used for authenticated data collection.
-
-For the stack, source layout, routing, data flow, and testing layers, see [ARCHITECTURE.md](ARCHITECTURE.md).
-
-## Quick Start
-
-```bash
-just install
-just dev
-```
-
-## Regenerating API types
-
-The TypeScript API types are autogenerated from the backend OpenAPI schema and written to `src/types/api.generated.ts`.
-
-That generated OpenAPI output is the only supported frontend contract for the
-RPi camera integration. The private backend\<->plugin seam lives in the
-published `relab-rpi-cam-models` Python package and should not be imported or
-re-declared directly in frontend code.
-
-To regenerate locally (backend must be running and `EXPO_PUBLIC_API_URL` set):
-
-```bash
-# simple regeneration
-pnpm run codegen:api
-
-# regenerate and automatically redact any embedded JWT examples
-pnpm run codegen:api:redact
-```
-
-The Expo dev server runs on <http://localhost:8081>.
-
-You will usually want the backend running as well. If the API is not on localhost, set `EXPO_PUBLIC_API_URL` in `.env.local`.
-
-To enable Google OAuth on web, set `EXPO_PUBLIC_GOOGLE_WEB_CLIENT_ID` to your web OAuth client ID from Google Cloud Console. See [CONTRIBUTING.md](../.github/CONTRIBUTING.md#frontend-setup) for details.
-
-## Common Commands
-
-```bash
-just check       # lint
-just test        # fast Jest unit tests
-just test-integration  # slower Jest integration tests
-just test-e2e    # Playwright browser E2E
-just test-ci     # CI-style Jest run with coverage
-just format      # format code
-just build-web   # export web build for E2E
-pnpm run lint:react            # strict React hooks/compiler + Fast Refresh ESLint pass
-pnpm run profile:compiler:web  # local web profiling with production/staging compiler transforms enabled
-```
-
-## Test Layers
-
-The app uses three test layers with different speed and confidence tradeoffs:
-
-- `unit`: fast Jest tests for pure logic, smaller hooks, isolated components, and API helpers
-- `integration`: slower Jest tests for screen composition, router behavior, provider stacks, and MSW-backed user flows
-- `e2e`: Playwright browser flows against a built web app
-
-`just test` and `pnpm test` run the full Jest suite (unit + integration).
-
-Use explicit commands when you need a narrower or broader scope:
-
-```bash
-just test-unit         # fast unit suite only
-just test-integration  # app-level Jest integration tests
-just test-e2e          # Playwright browser E2E (requires `just build-web` and compose.e2e.yaml running)
-pnpm run test:ci       # unit + integration with CI flags and coverage
-```
-
-Jest integration tests in this repo still run in-memory with `jest-expo` and React Native Testing Library. They are broader than unit tests, but they are not a substitute for device-native end-to-end coverage.
-
-## Timing Jest Suites
-
-To profile slow test files, run Jest with JSON output and inspect the report:
-
-```bash
-pnpm test -- --runInBand --json --outputFile=.jest-timings.json
-```
-

-For emulator and device setup, testing patterns, and app-specific development notes, see [CONTRIBUTING.md](../.github/CONTRIBUTING.md#frontend-development).
-
-## Styling And Theming
-
-Styling in `frontend-app` now follows a single-theme setup built on React Native Paper MD3.
-
-- Import theme values from `@/theme`, not from `src/assets/themes/*`
-- Use `useAppTheme()` as the default hook for theme access
-- Prefer semantic tokens like `theme.tokens.status.live`, `theme.tokens.text.muted`, and `theme.tokens.surface.accent` over raw hex or `rgba(...)` literals
-- Keep static layout in `StyleSheet.create()`
-- For theme-dependent styles, use small colocated factories like `createStyles(theme)`
-- Keep `src/app/` route-only; router helpers belong under `src/lib/router/`
-
-In practice, that means:
-
-- `src/theme/` is the only supported theme entrypoint
-- shared visual primitives should live under `src/components/base/` or `src/components/common/`
-- new hard-coded color literals in app code should be treated as regressions unless they belong in the theme layer, generated assets, or tests
-
-## React Performance Profiling
-
-Memoization changes in this app should be validated in a release-like build, not only in Metro dev mode.
-
-1. Run `pnpm run profile:compiler:web` to start Expo web with `BUILD_MODE=production`, which keeps the React Compiler enabled locally without changing the normal `dev` workflow.
-1. Open the app in a browser with React DevTools installed and record the interaction in the Profiler tab.
-1. Confirm the slow interaction in the profiler before changing memoization.
-1. Re-profile after the change and keep manual `useMemo` / `useCallback` / `React.memo` only where the compiled build still benefits.
-
-The default `pnpm run dev` flow intentionally keeps compiler transforms off for faster Metro feedback while you iterate.
-
-## Lint Ownership
-
-Biome remains the primary formatter/linter for this app, including the React rules it supports well today:
-
-- hook ordering and dependency linting
-- React prop assignment safety
-- general React module/export safety where configured
-
-ESLint is intentionally narrow and only runs the React compiler-era checks that Biome does not cover well yet. It also enforces explicit Fast Refresh export-only structure via `eslint-plugin-react-refresh`.
-
-The React ESLint pass is blocking, not advisory. `pnpm run lint:react` must pass with zero warnings.
-
-Key ESLint coverage includes:
-
-- `react-hooks/preserve-manual-memoization`
-- `react-hooks/static-components`
-- `react-hooks/config`
-- `react-hooks/gating`
-- `react-hooks/unsupported-syntax`
-- `react-hooks/globals`
-- `react-hooks/error-boundaries`
-- `react-hooks/set-state-in-render`
-- `react-refresh/only-export-components`
-
-Biome is still the only lint tool we plan to use for React Native-specific checks in this app, but the currently published Biome release used here does not yet expose the RN rule surface we wanted to enable. RN-specific linting therefore remains intentionally minimal for now.

-#!/usr/bin/env node
-/*
-  redact_api.js
-
-  Purpose: remove any example JWTs embedded by the OpenAPI -> TypeScript
-  generator from the generated frontend file `src/types/api.generated.ts`.
-
-  Why: some OpenAPI examples may contain real-looking tokens that trigger
-  gitleaks or other secret-scanning tools. This script performs a simple
-  regex replace to substitute such `access_token` example values with
-  the safe placeholder `<REDACTED_JWT>` so generated files are safe to
-  commit and publish.
-
-  Behavior:
-  - Locates `api.generated.ts` in common paths relative to CWD.
-  - Replaces any value matching the pattern used for JWT-like strings
-    in `"access_token": "..."` with `"access_token": "<REDACTED_JWT>"`.
-  - Only writes the file if a change was made.
-
-  Usage:
-    # from frontend-app
-    pnpm run codegen:api:redact
-    # or directly
-    node scripts/redact_api.js

-/**
- * LL-HLS live preview for a single camera.
- *
- * Web: renders a ``<video>`` element with [hls.js](https://github.com/video-dev/hls.js/)
- * attached to the playlist URL. When ``connectionInfo.mode`` is ``"local"``, the
- * URL routes through the Pi's FastAPI HLS proxy (``/preview/hls/`` on port 8018) which
- * forwards to MediaMTX internally — this lets FastAPI attach CORS and Private
- * Network Access headers to every response, including HLS segments. Latency is
- * ~0.4–0.8 s. Otherwise the backend HLS proxy is used (~1.5–3 s via relay).
- * Safari/iOS-on-web uses the browser's native HLS playback path.
- *
- * Native (iOS/Android in the Expo app): uses ``expo-video`` which speaks HLS
- * out of the box. Same URL switching logic applies.
- *
- * Either way, the parent only needs to pass a camera; URL selection is handled
- * internally based on the connection mode.

- * imperative ``<video>`` element and the dynamic ``hls.js`` import; testing
- * those internals requires a full jsdom environment with Fetch API polyfills
- * that would conflict with the project's MSW setup, so the web path stays
- * covered by manual browser testing instead. The goal here is to lock in
- * everything unit-testable in a node test env.

-/**
- * Local direct-connection mode for RPi cameras.
- *
- * When a camera is physically connected to the same machine via Ethernet or a
- * USB-C to Ethernet adapter, the frontend can bypass the backend WebSocket relay
- * and talk directly to the Pi's FastAPI (:8018) and MediaMTX (:8888) endpoints.
- *
- * Benefits:
- *  - LL-HLS preview latency drops from ~1.5–3 s to ~0.4–0.8 s
- *  - Works with no internet connection
- *  - Lower backend bandwidth usage
- *
- * The relay connection on the Pi keeps running in parallel, so remote users
- * accessing the same camera via the backend continue to work unchanged.
- *
- * ## Auto-configuration (medium-term / zero-copy setup)
- *
- * When the camera is online, the hook fetches local access info through the
- * relay (GET /cameras/{id}/local-access → Pi's /system/local-access). The Pi
- * returns its API key and all its LAN IP addresses. The hook probes each
- * candidate URL in parallel; the first that responds activates local mode
- * automatically — no manual key copying required.
- *
- * If the camera is offline or the relay call fails, the hook falls back to
- * any previously-stored URL/key or the USB gadget default address. Users can
- * still configure manually via the returned `configure()` function.
- *
- * Usage:
- *   const conn = useLocalConnection(cameraId, { isOnline });
- *   // conn.mode: 'probing' | 'local' | 'relay'
- *   // conn.localBaseUrl, conn.localApiKey populated when mode === 'local'

-# RELab Web
-
-This subrepo contains the public website for RELab, built with Astro. It is the small, mostly static front door for the project: the landing page, privacy page, newsletter flows, and the links that point people toward the app, docs, and backend services.
-
-If you are looking for the main application itself, that lives elsewhere in the monorepo. This package is the website around the project, not the research workflow UI.
-
-## Quick start
-
-Run commands from `frontend-web/`.
-
-```bash
-just install
-pnpm run dev
-```
-
-The local dev server runs at <http://localhost:8081>.
-
-In the full Docker stack, the site is served behind Caddy at <http://localhost:8010>.
-
-## What is here
-
-- `src/pages` for route-level Astro pages
-- `src/components` for shared UI building blocks
-- `src/layouts` for the document shell
-- `src/scripts` for the small amount of client-side JavaScript
-- `src/content` for site copy and structured content
-- `src/config` for environment handling and shared config helpers
-- `src/styles` for the CSS layers and design tokens
-- `e2e` for Playwright browser tests
-
-## Common commands
-
-Use `just` if you want the repo-standard task runner, or `pnpm run` if you prefer package scripts.
-
-| Task                    | Command            |
-| ----------------------- | ------------------ |
-| Install dependencies    | `just install`     |
-| Start local dev server  | `pnpm run dev`     |
-| Build production output | `pnpm run build`   |
-| Preview a build locally | `pnpm run preview` |
-| Lint and type-check     | `just check`       |
-| Format files            | `just format`      |
-| Auto-fix Biome issues   | `just fix`         |
-| Run unit tests          | `just test`        |
-| Run browser E2E tests   | `just test-e2e`    |
-
-## Development notes
-
-- Astro does most of the work here. The site is intentionally light on client-side JavaScript.
-- Biome handles linting and formatting.
-- Vitest covers utilities and small DOM scripts.
-- Playwright covers the browser flows and accessibility checks.
-- Production output is served by Caddy from `dist/`.
-
-## Environment variables
-
-Public variables are read through `import.meta.env` and used by [src/config/public.ts](src/config/public.ts).
-
-| Name                   | Required | Purpose                            |
-| ---------------------- | -------- | ---------------------------------- |
-| `PUBLIC_API_URL`       | yes      | Backend API base URL               |
-| `PUBLIC_APP_URL`       | yes      | Canonical app URL                  |
-| `PUBLIC_SITE_URL`      | yes      | Canonical site URL                 |
-| `PUBLIC_DOCS_URL`      | yes      | Canonical docs URL                 |
-| `PUBLIC_LINKEDIN_URL`  | no       | LinkedIn group link for the footer |
-| `PUBLIC_CONTACT_EMAIL` | no       | Public contact address             |
-
-Tooling also reads a small runtime config surface from [config/runtime.ts](config/runtime.ts).
-
-| Name       | Purpose                                                                        |
-| ---------- | ------------------------------------------------------------------------------ |
-| `BASE_URL` | Run Playwright against an existing site instead of spinning up a local preview |
-| `CI`       | Tightens Playwright reporting and retry behavior in CI                         |
-
-## Testing
-
-Unit tests live next to the code they cover as `*.test.ts`.
-
-```bash
-pnpm vitest run src/scripts/theme.test.ts
-pnpm vitest
-```
-
-E2E tests live in `e2e/`. By default, Playwright builds the site and starts a preview server when `BASE_URL` is not set. To run against the Docker stack instead:
-
-```bash
-BASE_URL=http://localhost:8010 pnpm run test:e2e
-```
-

+# Relab Cloudflare zone configuration
+
+Zone-scoped configuration for `cml-relab.org`, managed with OpenTofu:
+
+- TLS zone settings (minimum version, TLS 1.3, always-use-HTTPS)
+- the three entrypoint rulesets: `http_ratelimit`,
+  `http_request_cache_settings`, `http_request_firewall_custom`
+
+## Why this is a separate root
+
+Cloudflare allows exactly one entrypoint ruleset per (zone, phase), and prod and
+staging share this zone. Owning these from either environment's workspace meant the
+last apply won — so they live here instead, with a single `default` workspace and no
+environment variable at all.
+
+The rules deliberately match **both** environments' hostnames. That is not an
+oversight: one ruleset protects the whole zone, so it has to cover every environment
+in it. The hostname map is `hostnames.tf`, a symlink to the one in `../cloudflare`.
+
+**Everything here affects prod and staging together.** A change to the TLS floor or a
+firewall rule lands on every hostname in the zone at once.
+
+## Rules adopted from the hand-configured zone
+
+Two rules that existed in the live zone before adoption are reproduced here, because
+dropping them would have been a silent regression:
+
+- **`relab_prod_html_bypass`** — the prod web and app entry points bypass the edge
+  cache. Their URLs do not change between deploys, so a cached entry point keeps
+  serving the previous build.
+- **`relab_telemetry_ingress_skip_managed_security`** — `otlp.` accepts
+  shipped telemetry from a non-browser client that Cloudflare's bot products would
+  otherwise challenge, and a challenged log push is a silently dropped log.
+
+Two others were dropped **deliberately**, and are recorded in `locals.tf` next to the
+rules that replaced them: a bypass for `rpi-cam-*` hostnames that nothing serves any
+more, and a restatement of Cloudflare's own default extension caching.
+
+### The telemetry credential
+
+The telemetry rule is gated on a shared secret, supplied as a variable so it never
+enters the repository:
+
+```bash
+export TF_VAR_telemetry_edge_key='...'  # same value as TELEMETRY_EDGE_KEY in the deploy hosts' .env
+```
+
+It is matched against a dedicated `X-Telemetry-Key` header, **not** the OTLP
+bearer token: Cloudflare stores ruleset expressions in cleartext and returns them from
+the rulesets API, so matching the Authorization value (as the adopted rule originally
+did) would disclose the collector credential to any zone-read grant. The deploy hosts
+send both headers — the token authenticates at the collector, the key only buys the
+managed-security skip — and the two rotate independently.
+
+> **Sharing the zone with the monitoring stack is fine today — keep it that way.**
+> `otlp.cml-relab.org` belongs to CMLPlatform/monitoring, which runs its own Cloudflare
+> Terraform against this same zone. Checked on 2026-08-19: its `infra/main.tf` declares a
+> tunnel, two DNS records (`grafana.`, `otlp.`) and a Zero Trust Access application —
+> and **no `cloudflare_ruleset`**, so nothing there contends with this root.
+>
+> That is a property to preserve, not a guarantee. Cloudflare allows one entrypoint
+> ruleset per (zone, phase), and that constraint does not stop at a repository boundary:
+> if the monitoring stack ever adds a WAF, cache or rate-limit ruleset for this zone,
+> whichever applied last would silently erase the other's rules. Rules for its hostnames
+> belong here, in the single owner, the way the telemetry skip rule does.
+
+Leaving it unset **omits the rule** rather than relaxing it — a rule that skipped
+managed security for any request to the telemetry host would be worse than no rule.
+That also means a plan run without it will propose **deleting** the live rule, so export
+it whenever you plan this root, and rotate it together with the deploy hosts'
+`OTLP_AUTH_TOKEN` — the same token, in the header form `Bearer <token>`.
+
+## What this zone's Cloudflare plan allows
+
+Two limits were found by an apply failing halfway, so they are now asserted in
+`tests/zone.tftest.hcl` rather than rediscovered:
+
+- **The `http_ratelimit` phase is heavily constrained on the Free tier:** one rule, a
+  10-second counting period, a 10-second mitigation timeout, and only Path and Verified
+  Bot usable as expression fields — `http.host` is not allowed. The single slot goes to
+  the auth endpoints: unauthenticated, the usual credential-stuffing target, and edge
+  blocking keeps the flood off the origin. Scoping by path alone is safe because
+  `/v1/auth/` is served by nothing but the api hostnames.
+
+  The rule sits at 10 requests / 10s, deliberately far above the application limits
+  behind it (login 3/min, register and reset 3–5/hour, in
+  `backend/app/api/auth/config.py`). The backend does the precise per-endpoint
+  enforcement; this only stops volume, and staying loose keeps it from ever being what
+  blocks a real person. Endpoints that lost their edge rule keep their own limiter
+  dependencies, so none is left with no limit at all.
+
+- **No `matches` (regex) operator.** It needs a Business or WAF Advanced plan. The
+  affected expressions use `starts_with`/`ends_with` instead. This one is worth catching
+  in tests specifically because it fails at *apply* time, partway through, after other
+  resources have already changed.
+
+Raising either would mean a paid Cloudflare plan. Both are recorded in `locals.tf` next
+to the rules they shaped.
+
+## Commands
+
+From the repository root:
+
+```bash
+just cloudflare-check       # covers this root and ../cloudflare
+just cloudflare-zone-plan
+just cloudflare-zone-apply YES
+```
+
+Per-environment resources (tunnels, DNS records, tunnel ingress) live in
+[`../cloudflare`](../cloudflare), whose README carries the shared setup: API token
+scopes, where state lives, state encryption, and the import workflow used to adopt
+existing resources.

+# Relab Cloudflare Edge
+
+This directory manages Relab's **per-environment** Cloudflare edge with OpenTofu:
+
+- a Cloudflare Tunnel per environment
+- DNS records for that environment's public hostnames
+- tunnel ingress routes into the Compose `edge` network
+
+Zone-global configuration — TLS settings and the three entrypoint rulesets — lives in
+[`../cloudflare-zone`](../cloudflare-zone), because those resources belong to the zone
+rather than to either environment. See "Why two roots" below.
+
+Neither root manages application runtime settings, Compose services, secrets,
+databases, backups, or telemetry.
+
+## Managed resources
+
+`prod` and `staging` are separate OpenTofu workspaces with separate tunnels. The
+hostname map they share lives in `hostnames.tf`, which is symlinked into the zone root
+so both read one definition.
+
+## Why two roots
+
+Cloudflare allows exactly **one entrypoint ruleset per (zone, phase)**, and prod and
+staging share one zone (`cml-relab.org`). A workspace-per-environment layout cannot own
+a zone-scoped resource: whichever environment applied last would overwrite the other's
+rules, and the TLS zone settings had the same problem more quietly, being written
+identically by both.
+
+Splitting by scope removes the question rather than managing it:
+
+| Root               | Scope           | Workspaces        | Owns                                        |
+| ------------------ | --------------- | ----------------- | ------------------------------------------- |
+| `cloudflare/`      | per environment | `prod`, `staging` | tunnel, DNS records, tunnel ingress         |
+| `cloudflare-zone/` | the whole zone  | `default` only    | TLS settings, the three entrypoint rulesets |
+
+The zone rulesets deliberately match **both** environments' api hosts, so the single
+owner protects both. There is no `manage_shared_zone_rulesets` variable any more; the
+split replaced it.
+
+### One-time: completing the split (done on the staging host, 2026-08-20)
+
+Any edge workspace applied before the split can still hold the three zone settings
+and — because the pre-split root declared the zone entrypoint rulesets behind a
+default-TRUE variable — the three rulesets that now belong to the zone root. A plan
+for such a workspace would DESTROY the live rate-limit and firewall rules.
+
+**Check first.** In each edge workspace:
+
+```bash
+cd infra/cloudflare
+tofu workspace select staging   # and any other workspace that was ever applied
+tofu state list
+```
+
+A clean workspace lists only `cloudflare_dns_record.edge[...]` and the two tunnel
+resources — that is the verified state of the staging host's workspace, and nothing
+below applies to it. `state rm` on a clean workspace fails with "No matching objects
+found", which is confirmation, not an error.
+
+If the list DOES show `cloudflare_zone_setting.*` or `cloudflare_ruleset.*`, hand
+them over — `state rm` forgets them **without** deleting anything from Cloudflare,
+then the zone root imports them:
+
+```bash
+tofu state rm cloudflare_zone_setting.minimum_tls_version \
+              cloudflare_zone_setting.tls_1_3 \
+              cloudflare_zone_setting.always_use_https
+tofu state rm 'cloudflare_ruleset.rate_limiting[0]' \
+              'cloudflare_ruleset.cache_settings[0]' \
+              'cloudflare_ruleset.custom_firewall[0]' || true
+
+./generate-imports.sh zone > ../cloudflare-zone/imports.tf
+just cloudflare-zone-plan            # 0 to add; the TLS floor may show 1.0 -> 1.2
+just cloudflare-zone-apply YES
+rm ../cloudflare-zone/imports.tf
+```
+
+Order matters: `state rm` before the zone import, or two states briefly claim the same
+resources. Either way: a plan that proposes destroying a ruleset is this handover left
+unfinished, not something to approve.
+
+Current hostnames:
+
+- Production: `cml-relab.org`, `app.cml-relab.org`, `api.cml-relab.org`,
+  `docs.cml-relab.org`
+- Staging: `web-test.cml-relab.org`, `app-test.cml-relab.org`,
+  `api-test.cml-relab.org`, `docs-test.cml-relab.org`
+
+Zone settings enforce TLS 1.2+, enable TLS 1.3, and redirect HTTP to HTTPS.
+Tunnel origins use plain HTTP inside the private Compose `edge` network.
+
+Rulesets:
+
+- `http_ratelimit`: repo-managed API rate limits.
+- `http_request_cache_settings`: repo-managed cache rules.
+- `http_request_firewall_custom`: repo-managed custom firewall rules.
+
+Cloudflare rules should be changed in this directory, not in the dashboard. The
+dashboard is useful for inspection, events, and emergency debugging. If an
+emergency dashboard edit is ever made, copy the change back into OpenTofu and
+run a plan before the next apply.
+
+## Commands
+
+Run from the repository root:
+
+```bash
+just cloudflare-check              # both roots; no credentials, no network, no state
+
+just cloudflare-plan staging       # per-environment root
+just cloudflare-apply staging YES
+
+just cloudflare-zone-plan          # zone-global root — affects BOTH environments
+just cloudflare-zone-apply YES
+```
+
+`cloudflare-check` covers **both** roots: format, validate, and `tofu test` with the
+Cloudflare provider mocked. The per-environment tests assert that staging serves only
+`-test` subdomains, that prod serves the apex, that the two never share a hostname, and
+that the tunnel ingress ends in the catch-all. The zone tests assert that every ruleset
+rule matches both environments' api hosts and that the cache rules stay disjoint.
+
+`cloudflare-check` is local/static apart from provider downloads. `plan` and
+`apply` require Cloudflare credentials and IDs. `apply` is guarded by `YES` or
+`FORCE=1`.
+
+Required environment variables:
+
+```bash
+export CLOUDFLARE_API_TOKEN='...'
+export TF_VAR_cloudflare_account_id='...'
+export TF_VAR_cloudflare_zone_id='...'
+export TF_VAR_state_passphrase='...'      # >= 16 chars, see State Encryption
+```
+
+Keep them in one file outside the repo and source it, rather than re-exporting per
+shell — a half-set environment is the most common way these commands fail:
+
+```bash
+chmod 600 ~/.config/relab-cloudflare.env && . ~/.config/relab-cloudflare.env
+```
+
+Optional:
+
+```bash
+export TF_VAR_cloudflare_zone_name='cml-relab.org'
+```
+
+Do not commit tokens, tunnel tokens, or state files.
+
+## API Token Scopes
+
+Create the token under **My Profile -> API Tokens -> Create Custom Token**. It needs
+two policy rows, because the tunnel is an account resource while everything else is
+scoped to the zone:
+
+| Scope                   | Permission                            | Access | Required by                                      |
+| ----------------------- | ------------------------------------- | ------ | ------------------------------------------------ |
+| Account (Relab account) | Cloudflare Tunnel                     | Edit   | `cloudflare_zero_trust_tunnel_cloudflared`       |
+| Account (Relab account) | Cloudflare One Connector: cloudflared | Edit   | `..._tunnel_cloudflared_config` ingress rules    |
+| Zone (`cml-relab.org`)  | DNS                                   | Edit   | `cloudflare_dns_record`                          |
+| Zone (`cml-relab.org`)  | Zone Settings                         | Edit   | `cloudflare_zone_setting`                        |
+| Zone (`cml-relab.org`)  | Zone WAF                              | Edit   | `http_ratelimit`, `http_request_firewall_custom` |
+| Zone (`cml-relab.org`)  | Cache Rules                           | Edit   | `http_request_cache_settings`                    |
+| Zone (`cml-relab.org`)  | Zone                                  | Read   | zone lookup                                      |
+
+Some accounts still label the tunnel permission **Argo Tunnel (Legacy)**; it is the same
+grant ("create and delete Cloudflare Tunnels"). Do not substitute Cloudflare One
+Networks, which covers WARP routes and virtual networks that this config does not use.
+
+Grant nothing else. Bot Management, Access, Page Rules, Cache Purge, Zone DNS Settings,
+and a blanket Zone Write are not used here and widen the blast radius of a leaked token.
+Scope the zone row to `cml-relab.org` alone rather than all zones, and set an expiry.
+
+Verify before the first plan:
+
+```bash
+curl -s https://api.cloudflare.com/client/v4/user/tokens/verify \
+  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" | jq .
+```
+
+A missing scope surfaces during `plan`/`apply` as a 403 naming the resource or ruleset
+phase; add that one permission rather than broadening the token.
+
+## Import Workflow
+
+Anything that already exists in Cloudflare must be imported before the first apply,
+or the plan will try to *create* it: duplicate DNS records, a second tunnel whose id
+does not match the live `CLOUDFLARE_TUNNEL_TOKEN`, and — worst — a replacement for the
+one entrypoint ruleset a phase allows.
+
+`generate-imports.sh` writes the `import` blocks for you, looking up every id through
+the API so none is transcribed by hand. Review the file, plan, apply, then delete it:
+import blocks re-run on every plan until removed.
+
+```bash
+cd infra/cloudflare
+./generate-imports.sh edge prod > imports.tf     # or: edge staging
+cat imports.tf                                   # read it before running anything
+just cloudflare-plan prod                        # expect 0 to add
+rm imports.tf                                    # only after the apply succeeds
+```
+
+The zone root is adopted the same way:
+
+```bash
+./generate-imports.sh zone > ../cloudflare-zone/imports.tf
+just cloudflare-zone-plan
+```
+
+The script resolves every id before it writes anything, so a failure leaves no
+half-written file. A missing tunnel or DNS record is a hard error — those exist and
+importing them is the whole point. A ruleset phase with no ruleset is different: that is
+a legitimate state, so the script warns on stderr, omits that block, and lets the apply
+create the entrypoint.
+
+Note that rulesets take a scope-prefixed import id (`zones/<zone_id>/<ruleset_id>`),
+unlike every other resource here, which take a bare `<zone_id>/<id>`.
+
+A correct adoption ends with a plan of **0 to add, 0 to destroy**. Anything else means
+an import is missing or wrong — stop rather than applying.
+
+Keep rule `ref` values stable. Cloudflare uses them to track rules across
+reordering.
+
+## Where state lives
+
+State is local, under `terraform.tfstate.d/<workspace>/`, gitignored and encrypted. For
+one operator applying a handful of times a year, that is the proportionate answer: a
+remote backend's main product is locking between concurrent applies, and there are no
+concurrent applies.
+
+The usual objection to local state — "lose the machine, lose everything" — does not hold
+here, because every resource is adopted by script. Losing the state costs a re-import
+(see Import Workflow), not a reconstruction. It is still worth keeping a copy somewhere
+private if the passphrase is ever the only thing standing between a stolen laptop and
+your tunnel secret.
+
+**Never commit the state**, encrypted or not: this repository is public, and an encrypted
+blob published permanently is a passphrase brute-force target with no expiry.
+
+Revisit this if a second person ever applies, or if CI does — that is the point where a
+remote backend with locking stops being ceremony.
+
+## State Encryption
+
+State and plan files hold the Cloudflare tunnel secret, so `versions.tf` configures
+OpenTofu state encryption (PBKDF2 + AES-GCM), enforced with no plaintext fallback. Export
+a passphrase of **at least 16 characters** before any command that reads or writes state:
+
+```bash
+export TF_VAR_state_passphrase='...'   # >= 16 chars
+```
+
+- `just cloudflare-check` never needs the passphrase: it copies each root to a
+  throwaway directory and verifies that, so `init` never opens an initialized
+  workspace's state. That also keeps an adoption-time `imports.tf` from crashing the
+  mocked-provider test run.
+- `just cloudflare-plan`, `just cloudflare-apply`, and `tofu state`/`workspace` commands
+  fail closed without one, reporting `no passphrase provided`. That is deliberate — it
+  beats silently writing the tunnel secret in plaintext.
+- Encryption is `enforced = true` with no plaintext fallback, so a missing passphrase
+  fails closed rather than silently writing the tunnel secret in the clear.
+- Use the same passphrase every time. A lost passphrase means a lost state file — which
+  costs a re-import (`generate-imports.sh`, a few minutes), not a rebuild. That is why
+  encryption can be enforced here without it being a hazard.
+- Keep the passphrase in the operator's password manager, not in the repo or shell
+  history.
+
+Keep prod and staging state separate. A remote encrypted backend with locking is still
+required before a second operator or CI applies changes — encryption at rest does not
+give concurrent applies a lock.

+# Design System: Relab — Web
+
+## Overview
+
+**Creative North Star: "Cyanotype & Manila — the colour of engineering documentation."**
+
+Before a product can re-enter the loop, someone has to document how it was made. Cyanotype blue
+is the colour of that record; manila is the tag tied to the part. The www surface is where that
+record is shown to people who have not seen it yet, so the site does not decorate the research.
+It *is* a document about the research, reproduced at web scale. A visitor's first viewport is a
+claim on the left and a real teardown schedule on the right, printed in duotone blue, because the
+evidence is the pitch.
+
+The form language is **Flat & Sharp**: the geometry of an engineering document. There is no
+frosted chrome, no card shadow, no rounded-pill anything. Depth is done the way a drafting sheet
+does it: a 1px hairline, a shade of surface, and generous vertical space. The page is one
+continuous document rather than a stack of panels: sections are separated by a rule and by
+`padding-block`, and carry no fill or radius of their own. Exactly one surface on the site earns
+a frame, and it earns it by being a document reproduced inside a document.
+
+Density is calm but not sparse. Prose is capped at a real measure (44rem for read-mode pages,
+48–80ch for individual blocks). Figures are set in tabular mono, and every heading is IBM Plex
+Serif, so the type register alone tells you whether you are reading a claim or a measurement.
+Motion exists only where it reports something: a figure refreshing, a bar being measured, a
+schedule dealing itself out of its assembly, a brand mark handing off to the header. Nothing
+bounces, nothing floats, and nothing animates purely to prove it can.
+
+**Key Characteristics:**
+
+- Cyanotype blue for every interaction; manila reserved for data labels
+- Flat and sharp: hairlines and surface tone instead of shadow
+- IBM Plex superfamily, three voices: Serif for headings, Sans for prose, Mono for data
+- One document, not a deck of panels: sections divided by a rule, never by a card
+- Photographs are duotoned into the palette so a wall of bench shots reads as one schedule
+- WCAG 2.2 AA, with contrast reasoning written into the token file itself
+
+**On the duplicated brand rules below — the duplication is deliberate.** Several rules here
+(accent, eyebrows, elevation, radius, the typeface split) are restated in full from
+`assets/DESIGN.md` and also appear in `docs/DESIGN.md` and `app/DESIGN.md`. That is not sloppiness
+and must not be "helpfully" deduplicated into a citation.
+
+The reason is mechanical. Whoever edits a component reads the design file next to it and does not
+open a second one, so a rule that lives only as a cross-reference is a rule nobody follows.
+`assets/DESIGN.md` is worse than inconvenient here: it sits at a path no design tooling looks in,
+which searches a subrepo root and the repo root only. A pointer to it is enforced by nothing.
+
+Each restatement therefore carries a `Mirrors assets/DESIGN.md:NN` marker.
+Run `rg "Mirrors assets/DESIGN.md"` to list every copy across the repo and check them against
+source in one command. `assets/DESIGN.md` remains the place to change a rule first.
+
+## Colors
+
+A Prussian-blue-on-cool-paper palette in a strict light/dark pair, with one warm ochre held in
+reserve for data.
+
+Every value below is authored as a `light-dark()` pair in `src/styles/brand.css` and
+`src/styles/tokens.css`. Those two files are the normative source, and the pair is the value: the
+frontmatter above carries only the light half, because its schema has no room for both. Read the
+dark half from the stylesheet, and never flatten a pair to a single hex. Radius, shadow, scrim, and
+the categorical chart ramp live in `src/styles/tokens.generated.css`, which is generated from
+`assets/tokens.json` by `scripts/sync_brand_assets.py`:
+**that file is never edited by hand, and its values are not editable from here.**
+
+### Primary
+
+- **Cyanotype Blue** (`--color-primary`): the brand anchor and the site's entire interaction
+  vocabulary: links, the filled CTA, the outline button's label, focus rings, the drafting grid
+  behind the blueprint panel, and the duotone that tints every photograph.
+- **Prussian Deep** (`--color-primary-strong`): the state shade. Filled buttons deepen to it on
+  hover; the outline button and the selected segmented toggle wear it as label ink.
+- **Blue Wash** (`--color-primary-soft`): an 8% (14% dark) tint of the primary. The canonical
+  tinted-fill: outline-button hover, selected measure toggle. It is the only "filled" state that
+  is not a solid.
+
+### Secondary
+
+- **Manila** (`--color-accent`): the ochre of a parts tag. A data-label colour only, and on www it
+  is deliberately almost absent. See the Accent Rule below.
+
+### Tertiary
+
+- **Data-Viz Blue** (`--color-chart-mark`): the primary brightened into the data-viz band, because
+  the brand blues are tuned for text and links, not for large fills. It is the only ink allowed on
+  a bar: the stats activity chart's columns, the crosshair dot, and every mass-share bar in the
+  teardown schedule.
+
+### Neutral
+
+- **Ink** (`--color-text`): body prose across the site.
+- **Heading Ink** (`--color-on-surface`): a cooler ink for headings, hero figures, part masses
+  and chart peak labels: anything that is a statement rather than a sentence. Cooler, not
+  stronger — it is slightly *below* Ink on the light ground (14.8:1 against 15.9:1) and slightly
+  above it in dark (17.0:1 against 15.9:1), so it is a register, not a contrast step. Both clear
+  AAA everywhere they are used; neither is load-bearing for legibility.
+- **Muted Slate** (`--color-muted`): secondary prose, captions, mono labels, nav-adjacent chrome,
+  step numbers, and every "this is context, not content" line. Deliberately distinct from the
+  shared brand `muted`; www's is a page-chrome override, and `tokens.css` says so.
+- **Ground** (`--color-page-surface`, the brand background): the page ground, and also the sticky
+  header's fill so the bar reads as part of the sheet rather than as a layer over it. It is the
+  paper half of every inverse pair too: the chart tooltip's text and the 2px ring that keeps the
+  tooltip dot legible where it crosses a bar are this token against `--color-on-surface`.
+- **Card** (`--color-surface-raised`, the brand surface): the tone of a teardown plate, the
+  drafting callout badge, and the theme toggle's face once a theme is explicitly chosen. It is a
+  *tint away from* the ground, not a step toward white: darker than the ground in light and
+  lighter in dark, which is how the shared brand system separates a card from its page.
+- **Hairline** (`--color-page-border`): the site's structural line. Every section divider, every
+  frame, every drafting rule. Translucent at 12% and measured at roughly 1.3:1 against the page,
+  because it separates content rather than identifying a control.
+- **Control Boundary** (`--color-control-border`): the border of anything whose border is the
+  *only* thing marking it as a control: outline buttons, the measure toggle group, the theme
+  toggle. Mixed 70% primary into the page ground rather than set solid, so it reads as chrome
+  rather than as a second primary action. Measured at 3.9:1 light and 5.1:1 dark to clear WCAG
+  1.4.11.
+- **Focus Ring** (`--color-ring`): solid brand primary, never a tint. A translucent ring lands
+  around 1.4:1 on both the page and card surfaces, well under the 3:1 that 1.4.11 requires. The
+  solid primary clears it at 7.5:1 light and 9.3:1 dark.
+
+### Named Rules
+
+**The Accent Rule.** Manila is a **data-label** colour: record IDs, live/status pills, small data
+highlights. It marks a *datum*, never a section. It never fills a button and never drives a
+hover or pressed state. Primary blue carries **all** interaction. And accent is for small text,
+never for mass: bars, big figures and any large element stay ink. When in doubt on something
+large, use ink. *Mirrors assets/DESIGN.md:173 — change it there first.*
+
+**The Two-Border Rule.** A border that separates or frames content uses the hairline
+(`--color-page-border`). A border that is the only thing identifying a control uses the control
+boundary (`--color-control-border`). Never reach for the hairline on an interactive edge: it
+measures ~1.3:1 and 1.4.11 wants 3:1.
+
+**The Mixed-Not-Raw Rule.** New tints derive from a token with `color-mix()`: the drafting grid
+is 7% primary, the plate frames 45% primary, the bar track 12% primary. Never introduce a raw hex
+into a component. There are exactly two hand-authored exceptions, and the values are recorded here
+so an audit does not have to re-derive whether each is drift:
+
+- `--color-chart-mark`: `light-dark(#2f6bc7, #6fa8ff)`, the primary brightened into the data-viz
+  band, because the brand blues are tuned for text and links rather than large fills.
+- The flipped button label ink: `light-dark(rgb(255,255,255), rgb(12,18,32))` on `.btn-primary`.
+  It inverts against the filled primary, so it cannot derive from the surface it sits on.
+
+Both are annotated in `tokens.css` and `components.css` where they live. The detector will flag the
+second as an undocumented colour. That finding is expected and should not be suppressed, because an
+ignore would also silence a genuinely new raw hex at the same value.
+
+## Typography
+
+**Display Font:** IBM Plex Serif 600 (with Georgia, serif)
+**Body Font:** IBM Plex Sans 400–600 (with Segoe UI, sans-serif)
+**Label/Mono Font:** IBM Plex Mono 400 (with monospace)
+
+**The Expo app deliberately diverges.** `app/` stays on platform system fonts (native feel,
+Dynamic Type support, zero load cost) and adopts only the *scale and palette*, not the typeface.
+Intentional, not drift: do not "unify" the app onto IBM Plex.
+*Mirrors assets/DESIGN.md:33 — change it there first.*
+
+**Character:** One superfamily, three voices that never blur. The serif gives headings the weight
+of a printed report without any editorial flourish. The sans is the neutral instrument panel
+around it. The mono is the register of the lab bench: every ID, count, mass and measurement is
+set in it with `tabular-nums` so columns of figures line up down the page. Faces are self-hosted
+latin subsets (`/fonts/*.woff2`, `font-display: swap`), with the Sans regular preloaded.
+
+### The ramp is now a token set, not a hand-authored scale
+
+`assets/tokens.json` defines the ramp and `scripts/sync_brand_assets.py` emits it into
+`src/styles/tokens.generated.css` as `--relab-type-{role}-size` / `-line`, plus
+`--relab-type-label-tracking`. Sizes are rem so browser font scaling works (WCAG 1.4.4); line
+heights are unitless ratios.
+
+**Use the token, not a literal.** Until this ramp was emitted, web had no type tokens at all (the
+generator defined the block and skipped it). So www hand-authored its scale and drifted to 18
+distinct sizes in the 11-25px band where the system defines six. Those 18 are now consolidated onto
+the ramp. A new literal `font-size` is drift by default. The detector flags it, and the correct
+response is to pick a role or add a step to `tokens.json`, never to add an ignore.
+
+| Role      | Size             | Line   | Use                                                   |
+| --------- | ---------------- | ------ | ----------------------------------------------------- |
+| `display` | 2.375rem (38px)  | 1.1579 | reserved; www uses fluid `clamp()` for display type   |
+| `title`   | 1.5rem (24px)    | 1.25   | record title, stat tile values                        |
+| `heading` | 1.1875rem (19px) | 1.2632 | section `h3`                                          |
+| `body`    | 1rem (16px)      | 1.625  | prose, nav and footer links, part rows                |
+| `data`    | 0.875rem (14px)  | 1.4286 | mono measurements, the hero metric line               |
+| `label`   | 0.8125rem (13px) | 1.3846 | uppercase tracked labels (`+0.1em`)                   |
+| `caption` | 0.8125rem (13px) | 1.3846 | captions, provenance, step detail                     |
+| `micro`   | 0.75rem (12px)   | 1.3333 | chart axis text, chips, colophon terms, plate indices |
+
+`micro` was added during the consolidation: www legitimately had six distinct sizes below 13px
+(chart labels at 11px, dense chrome at 12-12.8px), and the ramp's floor was 13. Folding them all
+upward would have visibly inflated the interface. The app has declined this step (its only sub-13
+values are drift it intends to fix), so `micro` is web-only for now.
+
+Two local aliases in `tokens.css` deliberately stay literals because neither lands on a ramp step:
+`--font-size-body-compact` (0.95rem) and `--font-size-meta` (0.94rem), both sitting between `data`
+and `body`. They are labelled as such in the file.
+
+`clamp()` declarations are untouched by the ramp: fluid display and headline type is chosen per
+viewport, not per step.
+
+### Hierarchy
+
+- **Display** (Serif 600, `clamp(2rem, 3.2vw, 2.375rem)`, 1.16, `-0.01em`): the hero headline and
+  every page `h1`. Capped at the brand's 38/44 display step and floored at 2rem so it still fits a
+  phone. Uses `text-wrap: balance` rather than a hand-tuned `ch` measure. A serif's "0" is a poor
+  proxy for mixed-case width, so balancing picks the break instead.
+- **Headline** (Serif 600, `clamp(1.6rem, 2.4vw, 2.2rem)`, 1.1): every section `h2`. Drops to
+  `clamp(1.35rem, 8vw, 1.95rem)` under 760px.
+- **Record Title** (Serif 600, `title` token = 1.5rem, 1.1): the featured record's name in the
+  teardown panel, and the stat tile values. Was a hand-authored 1.35rem before the consolidation.
+- **Subhead** (Serif 600, `heading` token = 1.1875rem, 1.1): section `h3`. Was 1.08rem.
+- **Body** (Sans 400, `1rem`/`1.625`): landing-page prose, footer copy. Blocks cap at 48–80ch;
+  read-mode pages cap the whole column at 44rem so headings and paragraphs share one measure near
+  the 75-character comfort ceiling.
+- **Body Compact** (Sans 400, `0.95rem`/`1.62`): read-mode pages and the denser landing blocks.
+  This is a deliberate density tier, not drift. `tokens.css` labels it as such.
+- **Label** (Mono 400, `0.8125rem`, `+0.1em`, uppercase, muted): phase names, colophon terms, the
+  stats subhead. A label names a *different* thing from the heading near it; it is never a
+  restatement.
+- **Data** (Mono 400, `data` token = 0.875rem, `tabular-nums`): the hero metric line and other
+  measurements read as figures. Masses use `white-space: nowrap` so a value never breaks away from
+  its unit.
+- **Caption** (Mono 400, `caption` token = 0.8125rem): provenance lines, the record link, step
+  detail, plate part names. One step below data: these describe a record rather than measure it.
+- **Micro** (`micro` token = 0.75rem): chart axis text, chips, colophon terms, plate indices, the
+  schedule extract line. Chart labels were 11px hard-coded in SVG and are now on the token.
+- **Meta** (Sans 400, `0.94rem`, often italic, muted): page meta lines, chart captions, the
+  affiliation line, the 9R aside. Italic marks it as an editorial note about the page rather than
+  part of it.
+- **Metric** (Sans 600, `clamp(2.4rem, 5vw, 3.6rem)`, 0.95, `-0.02em`): the one hero figure. Set
+  in *proportional* digits deliberately: `tabular-nums` gives every digit the width of a `0`,
+  which reads loose at display size. Tiles below it use `1.55rem`/600 with the same treatment.
+
+### Named Rules
+
+**The No-Eyebrow Rule.** www carries **no eyebrows or kickers**. A mono uppercase label that only
+restates the heading under it is chrome. Provenance lines sit *under* the title as captions, never
+above it as kickers. (This is web-specific: the app's `eyebrow` variant stays, because there it
+labels a value inside a compact tag rather than announcing a section. That is the Accent Rule
+wearing different clothes, not a separate rule.)
+*Mirrors assets/DESIGN.md:175 — change it there first.*
+
+**The Mono-Is-Measurement Rule.** Mono is reserved for things that were measured or assigned: an
+ID, a count, a mass, a date, a licence term. Prose is never set in mono to look technical.
+
+## Layout
+
+The site is a single centred column, not a grid system. `--frame-width` is 1280px and
+`--content-width` 1248px; the page shell is `min(100% - 2rem, 1248px)` with `2.75rem` of vertical
+padding, tightening to `min(100% - 1.25rem, …)` and `1.5rem`/`2rem` below 760px. The sticky header
+and the footer are full-bleed bars whose inner content aligns to that same column.
+
+Sections space themselves with `padding-block: 3rem` (2rem below 760px) and are divided by a 1px
+hairline `border-top`. The grid gap is explicitly set to `0` so the rule falls in the middle of
+the gap rather than at one edge of it. The first section in a shell drops both its rule and its
+top padding. Read-mode pages tighten the section rhythm to `1.6rem`. They run many more
+sections than the landing page, and 3rem would strand each clause on its own screen.
+
+Multi-column blocks are plain CSS grid with `minmax(0, 1fr)` tracks and a single collapse point
+each, chosen per block rather than from a shared breakpoint scale. The hero split (1fr/1fr,
+2.5rem gap) collapses at 1000px, the method flow (3 columns, 2rem) at 900px, the motivation beats
+and footer colophon at 860px, the general mobile treatment at 760px, the stats hero divider at
+620px, and the footer chrome again at 480px. The activity chart is the exception. Below 44rem it
+scrolls inside its own container with an edge mask rather than shrinking its labels toward
+illegibility. **The page itself never scrolls sideways.**
+
+Spacing rhythm runs on a loose rem scale rather than a strict 4/8 grid: `0.3–0.4rem` inside a
+label/value pair, `0.6–0.9rem` between related rows, `1.4rem` between blocks in a panel, `2rem`
+between grid columns, `2.5rem` across the hero split. Touch targets hold the 44px floor even where
+the visible control is smaller: the theme toggle paints at 2.1rem and carries an invisible
+centred 44×44 `::after`; footer social links are 44×44 boxes around a 1.18rem glyph.
+
+## Elevation & Depth
+
+**This site has no elevation.** There is not a single `box-shadow` in `www/`, and no
+`backdrop-filter` either. The last one, a frosted sticky header, was removed because scrolled
+body text still read through it. Depth is entirely tonal and linear: a 1px hairline, a shade of
+surface, and space.
+
+The shared brand system does reserve one floating tier (`--relab-shadow-overlay` and
+`--relab-scrim`, both present in `tokens.generated.css`) for things that genuinely float: menus,
+dialogs, sheets, snackbars. **Nothing on www floats, so both tokens are currently unused here.**
+That is a fact worth preserving: if a future overlay needs a shadow, it uses that token and only
+that token, at that one tier.
+
+The two surface tiers (ground → card) are the brand's own neutrals. www
+used to hand-author a three-step ramp of its own (cool paper → near-white → white) because the
+brand vocabulary had no card tone on web; that gap closed, so the tiers point at
+`--relab-brand-background` and `--relab-brand-surface` instead of reconstructing them. The third
+tier went with the repoint: the brand defines a ground and a card, and nothing on the site needed
+a tone above the card that the ground could not carry as an inverse. Both are opaque; the one
+place that still mixes toward transparent is the teardown plate, at 82%, so the drafting grid
+under it reads through.
+
+### Named Rules
+
+**The No-Float Rule.** Inline surfaces (cards, rows, inputs, panels) are flat: 1px hairline plus
+surface fill, no shadow, ever. If something needs to look raised, it gets a border-colour change
+or a 2px lift, not a shadow. The teardown plate's hover is exactly this: the frame brightens to
+45% primary and the plate rises 2px. Shadow is reserved for one tier only, `shadow-overlay`, on
+surfaces that genuinely float. www never reaches it.
+*Mirrors assets/DESIGN.md:123 — change it there first.*
+
+## Shapes
+
+Corners are small and consistent, and they come from `tokens.generated.css`: **6px** for controls
+(buttons, the toggle group, chips, plate frames), **8px** for cards and panels (only the blueprint
+panel uses it on www), **12px** for overlays (unused here), and `9999px` for true pills (unused
+here, since nothing on this site is a pill).
+Radius scale *Mirrors assets/DESIGN.md:113 — change it there first.*
+Nested frames step down rather than repeat: a plate figure
+inside a 6px plate uses `calc(var(--radius-control) - 2px)`. The drafting callout in its corner
+carries that radius on one corner only, so it reads as printed into the frame rather than stuck
+onto it.
+
+Borders are the primary structural device and they are always 1px. The recurring silhouette is a
+rectangle with a hairline top rule and nothing else: motivation beats, method phases, the hero's
+affiliation line, and the footer's chrome band are all the same gesture at different scales. Bars
+are the one exception to sharpness: the mass-share bar is 4px tall with a 2px radius, small enough
+that a square end would read as a rendering artefact.
+
+Two textures recur, both mixed from the primary and never from a raw hex: the blueprint panel's
+1.5rem drafting grid at 7% primary, and the same grid at 0.75rem and 14% inside a blank plate. So
+an unphotographed part reads as an unexposed frame rather than as a hole.
+
+## Components
+
+### Buttons
+
+- **Shape:** Softly squared (6px control radius), inline-flex, 1px transparent border so outline
+  and filled variants share a box.
+- **Primary:** Filled cyanotype blue with white label ink, flipped to near-black in dark mode,
+  where the primary is a light blue. Padding `0.8rem 1.15rem`; the large hero variant holds a
+  `3.35rem` minimum height (`3.1rem` on mobile).
+- **Hover / Focus:** Background deepens to Prussian Deep over 160ms on the site's single easing
+  curve. Focus is the global 2px solid ring at 3px offset. Press is `scale(0.98)`, deliberately at
+  the threshold of perception. It is transform-only, so a press never reflows the row it sits in.
+- **Outline:** Transparent fill, control-boundary border, Prussian Deep label. Hover deepens the
+  border to full primary and fills with the 8% blue wash. **Never the accent.** The pair reads as
+  two doors (browse / contribute) rather than two competing pitches.
+- **Stacked:** Either variant can carry a second line: the label, then what it costs the visitor
+  ("No account needed"). The sublabel is 0.78rem/500 at 0.78 opacity, never dimmer, because it is
+  real information about what the button will ask for. Rows are baseline-aligned so both primary
+  labels sit on one line across the pair. Under 760px the button row becomes a single stretched
+  column.
+- **Disabled:** `cursor: progress`, 0.7 opacity.
+- **Reduced motion:** transitions collapse to 0.01ms and the press transform is dropped entirely.
+  The background change still acknowledges the press, because a 0.01ms scale is a jump, not motion.
+
+### Chips
+
+- **Style:** Hairline border, 6px radius, small uppercase mono in muted ink, `0.2rem 0.55rem`
+  padding. Used for the product-type tag on the featured record and the "repeats per part" marker
+  on the looping method phase.
+- **State:** Static. Chips on www are labels, not filters. No selected state exists.
+
+### Cards / Containers
+
+- **Corner Style:** 8px card radius on the one framed panel; 6px on the plates inside it.
+- **Background:** The blueprint panel is transparent over the page ground with a drafting grid
+  painted into it; plates are 82% raised paper over that grid, so the grid shows faintly through.
+- **Shadow Strategy:** None. See Elevation & Depth.
+- **Border:** 1px hairline throughout; plate frames brighten to 45% primary on hover or
+  focus-visible.
+- **Internal Padding:** `1.25rem` on the panel, `0.4–0.65rem` on a plate, `0.9rem` grid gap
+  between panel rows.
+
+### Inputs / Fields
+
+www has no text inputs. The only form controls are the segmented measure toggle and the theme
+toggle, documented under Navigation and Signature Component. If a field is ever added, it takes
+the control radius (6px), the control-boundary border, and the global focus ring.
+
+### Navigation
+
+- **Header:** Sticky, opaque page-ground fill, 1px hairline bottom rule, no shadow. Wordmark on
+  the left, two links (App, Docs) on the right; both rows wrap, so enlarged text at a narrow
+  viewport never forces sideways scroll. Links are 0.9rem/500 in heading ink, undecorated at rest,
+  turning primary and underlined on hover and focus-visible. GitHub is deliberately *not* here.
+  It is a project channel and lives once, in the footer.
+- **Footer:** Two bands. A research colophon set as mono uppercase terms in a 6.5rem track against
+  0.875rem definitions (collapsing to one column at 860px). Then comes the site chrome under a
+  hairline: copyright, policy links, contact, three brand marks, and the theme control behind a
+  vertical rule. Footer links are 0.95rem/500 muted, going primary and underlined on hover/focus.
+- **Brand marks:** GitHub, LinkedIn and YouTube are vendored monochrome SVGs filled with
+  `currentColor` at 1.18rem inside 44×44 targets. **Never recoloured into their own brand
+  palettes.**
+- **Brand handoff:** On the landing page the hero's mark melts upward over the first 140px of
+  scroll while the header's fades in behind it, so the brand is never on screen twice. Built on
+  `animation-timeline: scroll()` with longhand properties only (the minifier folds the shorthand
+  into something no browser parses). Firefox has no scroll-timeline support, so both marks stay
+  visible there for the whole page. This is an accepted fallback, not a bug, and the same
+  fallback applies under reduced motion.
+
+### Stats Panel
+
+- **Character:** A ledger, not a dashboard. One hero figure separated by a vertical hairline from
+  a wrapping row of tiles, then an activity chart under a mono uppercase subhead.
+- **Segmented toggle:** A single control row above what it scopes. The group carries the
+  control-boundary border, 6px radius, and `overflow: hidden`. Buttons are borderless 0.78rem/500
+  muted text that go heading-ink on hover and take the blue wash plus Prussian Deep ink when
+  `aria-pressed="true"`. Focus insets to `-2px` because the group clips its overflow.
+- **Chart:** Hand-built SVG. Grid lines and axis labels are recessive hairline and 11px mono
+  tabular; bars are the data-viz blue; the peak label and tooltip panel are heading ink with print
+  white text. Text never wears the data colour. The bar beside it carries identity. On first
+  reveal only, bars grow from their own baseline over 300ms with a 40ms stagger capped at 240ms.
+  Re-renders from the toggle paint at full height, because the toggle is a comparison control and a
+  ramp would delay the comparison.
+
+### Theme Toggle
+
+A 2.1rem square (1.9rem below 760px) with the control-boundary border, raised-paper fill and a
+0.92rem glyph, cycling system → light → dark. Hover deepens the border to full primary, matching
+the outline button; an explicit light or dark choice swaps the fill to print white and the glyph to
+heading ink. A 44×44 invisible `::after` carries the pointer target without inflating the visible
+box.
+
+### The Blueprint Schedule (signature component)
+
+`HeroTeardown.astro` is the site's showpiece and the largest single concentration of design risk:
+734 lines, and the only framed surface on the page. It renders a featured product teardown as an
+engineering parts schedule: a document reproduced inside a document, which is what earns it the
+frame everything else on the site is denied.
+
+- **Frame:** 1px hairline, 8px card radius, no shadow, `1.25rem` padding, and a 1.5rem drafting
+  grid mixed at 7% primary painted across the whole panel.
+- **Record header:** Title (serif 1.35rem) and product-type chip on one row, a mono provenance
+  caption under them ("Teardown №412 · live record"), and an index-print photograph of the
+  assembled product in a `clamp(6rem, 18vw, 8.5rem)` track at 4:3. The print is deliberately the
+  size of an index print, not a hero image. At the panel's full width, a larger image would dwarf
+  the parts, which are what the page is about. When there is no photograph the second track
+  disappears entirely rather than leaving a reserved gap.
+- **Two layouts, chosen by the data:** if any shown part carries a photograph the schedule becomes
+  a grid of plates (`repeat(auto-fill, minmax(9.5rem, 1fr))`); if none do, it stays a compact list.
+  Equal-width cells are what keeps the mass bars comparable across a grid the way they were
+  comparable down a list.
+- **The cyanotype:** every photograph is `grayscale(1) contrast(1.06)` under a primary-hue
+  `mix-blend-mode: color` layer. The blend takes hue and saturation from the tint and lightness
+  from the image, so a light area prints pale blue and a dark one Prussian. That is what a
+  cyanotype does. This is the whole reason a wall of inconsistent bench photographs reads as one
+  schedule. `isolation: isolate` keeps the blend inside its frame. In dark mode exposure stops down
+  to 0.6, the same correction a darkroom would make. So the plates read as prints on the page
+  rather than as light sources on it.
+- **Look-closer:** on hover or `:focus-visible` the duotone lifts to the real photograph, the frame
+  brightens to 45% primary and the plate rises 2px over 240ms. `:focus-visible`, not
+  `:focus-within`: clicking a disclosure would otherwise strand one colour photograph in a
+  schedule of blue prints. Nothing is hidden behind the pointer, so this owes no equivalent; the
+  keyboard gets it anyway.
+- **Drafting callout:** a square mono tabular index number tucked into the plate's top-left corner
+  with borders on two sides: the number a parts diagram writes next to a part, not a badge.
+- **Mass bar:** a 4px track at 12% primary with a data-viz-blue fill sized to the part's share of
+  the product's recorded mass. It animates its length in over 300ms because the length *is* the
+  datum: the bar arrives as a measurement being taken. Bars wait for their own plate to land.
+- **The one authored moment:** on load, plates deal themselves out of the assembly: each starts
+  stacked back toward the first cell, leaning, and settles into its seat over 420ms with a 42ms
+  stagger. The lean and delay both cap at index 6/10 so a twenty-part product neither flings plates
+  off the panel nor takes three seconds to finish. Fill is `backwards`, never `both`: a forwards
+  fill would keep re-applying the transform and swallow the hover rise.
+- **Disclosure:** parts with subcomponents use native `<details>`, closed in the baked HTML so
+  opening never counts as layout shift. The native marker is suppressed and replaced with a ▸/▾
+  glyph. The height transition rides on `interpolate-size: allow-keywords` plus
+  `::details-content` with `allow-discrete`, so older browsers keep the snap.
+- **Honesty:** the panel shows the six heaviest parts and says so ("Showing the 6 heaviest of 18
+  recorded parts"). A fixture instead of live data is labelled as such and carries no invented
+  record number. A schedule that quietly drops two thirds of a record is the one thing this panel
+  cannot afford to be.
+
+Everything here is baked at build time and paints without JavaScript.
+
+## Do's and Don'ts
+
+### Do
+
+- **Do** carry all interaction on primary blue: links, filled and outline buttons, hover, pressed,
+  selected, and focus states.
+- **Do** separate sections with a 1px hairline `border-top` and `padding-block`, and keep the grid
+  gap at 0 so the rule lands in the middle of the space.
+- **Do** set every ID, count, mass, date and measurement in IBM Plex Mono with `tabular-nums`, and
+  every heading in IBM Plex Serif.
+- **Do** use `--color-control-border` on any border that is the only thing identifying a control,
+  and `--color-page-border` on anything that merely separates or frames content.
+- **Do** derive new tints with `color-mix()` from an existing token (7% primary for a drafting
+  grid, 12% for a bar track, 45% for an active frame) rather than introducing a hex.
+- **Do** put a scroll-driven or load-driven animation only where it reports something real (a
+  figure refreshing, a bar measuring, a schedule assembling) and always behind
+  `prefers-reduced-motion: no-preference`.
+- **Do** keep a 44px pointer target even where the visible control is smaller, using an invisible
+  centred `::after` or a padded link box.
+
+### Don't
+
+- **Don't** fill a button with manila, or let the accent drive a hover, pressed or selected state.
+- **Don't** put manila on anything large: bars, hero figures, tiles and headings stay ink.
+- **Don't** write an eyebrow or kicker. A mono uppercase label that restates the heading beneath it
+  is chrome; put provenance *under* the title as a caption instead.
+- **Don't** add a `box-shadow` to an inline surface. There are none on this site, and the reserved
+  `--relab-shadow-overlay` tier is for things that genuinely float. Nothing on www does.
+- **Don't** reintroduce `backdrop-filter`. Blur is the last thing a document-grade brand should
+  hide its chrome behind, and the frosted header was removed for exactly that reason.
+- **Don't** reach for a utility framework. www styles with authored CSS in `src/styles/` plus
+  per-component scoped `<style>` blocks; consistency is enforced by the generated tokens, not by
+  a utility scale. Tailwind was installed here once, migrated five class attributes over three
+  commits, and was then contradicted by every component built after it -- the same round trip
+  docs made before removing it. Both subrepos now ship none.
+- **Don't** hand-edit `src/styles/tokens.generated.css`. It is generated from `assets/tokens.json`
+  by `scripts/sync_brand_assets.py`; change the source and run `just assets-sync`.
+- **Don't** let a chart or table force the page to scroll sideways. Give it its own
+  `overflow-x: auto` container with an edge mask, the way the activity chart does.
+- **Don't** use a `ch` cap to tune a serif headline's line breaks. Use `text-wrap: balance`; a
+  serif's "0" is a poor proxy for mixed-case width.
+- **Don't** show the brand mark twice at once. The hero's mark and the header's are a handoff, not
+  two logos.

+# Relab Web
+
+This subrepo contains the public website for Relab, built with Astro. It is the small, mostly static
+front door for the project: the landing page, privacy page, and the links that point people toward
+the app, docs, and source code.
+
+The main application lives in [`app/`](../app/). This package is the website around the project, not
+the research workflow UI.
+
+## Quick start
+
+Run commands from `www/`.
+
+```bash
+just install
+pnpm run dev
+```
+
+The local dev server runs at <http://127.0.0.1:8013>. Use the numeric loopback
+host when developing through VS Code Remote port forwarding; Firefox can be
+unreliable with forwarded `localhost` URLs.
+
+In the full Docker stack, the site is served behind Caddy at <http://127.0.0.1:8013>.
+
+## What is here
+
+- `src/pages` for route-level Astro pages
+- `src/components` for shared UI building blocks
+- `src/layouts` for the document shell
+- `src/scripts` for the small amount of client-side JavaScript
+- `src/lib` for shared helpers used by those scripts
+- `src/copy` for site copy kept as structured data
+- `src/config` for environment handling and shared config helpers
+- `src/styles` for the CSS layers and design tokens
+- `e2e` for Playwright browser tests
+
+## Common commands
+
+Use `just` for repo-standard tasks. `just build` loads `../deploy/env/prod.compose.env` so public
+URLs come from there instead of values duplicated here; see
+[Environment variables](#environment-variables) for how staging and production actually get their
+values.
+
+| Task                             | Command            |

+| Run the full CI pipeline locally | `just ci`          |
+| Regenerate the lockfile only     | `just lockfile`    |
+
+## Development notes
+
+- Astro does most of the work here. The site is light on client-side JavaScript.
+- Biome handles linting and formatting.
+- Vitest covers utilities and small DOM scripts.
+- Playwright covers the browser flows and accessibility checks.
+- Production output is served by Caddy from `dist/`.
+
+### The landing hero's teardown photography
+
+The hero schedule has two layouts and picks between them from the data, not from a flag. If any
+part of the featured teardown has a photograph it renders as a grid of plates — one duotoned
+cyanotype print per part, dealing out of the assembly on load. If none has one it stays the compact
+list it has always been, so a product with no component photography never becomes a wall of empty
+frames.
+
+Every plate is live data: `thumbnail_url` off each node of
+`/v1/products/{id}/components/tree`, which the build already fetches. Nothing is hand-authored, so
+the hero re-shoots itself whenever `PUBLIC_FEATURED_PRODUCT_ID` changes. Individual parts with no
+photo render as a blank lattice frame, which reads as an unexposed plate in the schedule.
+
+Plates lay out near 180px, so the 200px `thumbnail_url` alone would be upscaled on any 2x screen.
+Each read schema also carries `thumbnail_urls`, the API's pre-computed derivatives keyed by width
+(`THUMBNAIL_WIDTHS` is 200/800/1600, generated at upload; widths at or above the original are
+skipped, so the map is sparse). `toPhoto` turns those into a `srcset` and the component pairs it
+with a `sizes` hint, letting the browser fetch the 200px file on a 1x screen and the 800px one on a
+2x screen. One available width means no `srcset` at all rather than a one-candidate list.
+
+Two editorial rules, both stated on the page rather than applied silently:
+
+- **Parts are ranked by recorded mass, heaviest first**, not in the order the API returns them.
+  Recording order is roughly disassembly order, which puts product 464's three screws ahead of its
+  battery and scatters the share bars; ranked, the bars read as one descending distribution.
+- **The hero shows six parts.** All twelve of product 464's made the panel more than twice the
+  height of the pitch beside it, most of it below the fold. When parts are withheld the grid says
+  so underneath (`Showing the 6 heaviest of 12 recorded parts`). Shares stay fractions of the whole
+  product, so the truncated view still tells the truth about what it shows.
+
+Two data quirks the hero handles, both first seen on product 464: masses under 10 g print to two
+significant figures, because the grouped integer format turned a recorded 0.33 g screw into `0 g`
+— which is what the em dash for *no recorded mass* already means. And a product type imported from
+the CPV taxonomy carries its code in `name` and its label in `description`, so the tag shows
+`Tablet computer`, never `CPV: 302132`; a code with no label drops the tag entirely.
+
+Builds with no API access (CI, most local dev, the Playwright suite) fall back to
+`src/data/landing-fixture.json`, which now carries a lab-shot photograph per part in
+`public/images/teardown/`, so those builds render the grid rather than the list — and the Playwright
+suite asserts the plates decode, which is what catches a fixture pointing at a file that never
+shipped. The masses are illustrative and the page says so; the photographs are real.
+
+Fixture photos are 800×600 WebP (4:3, `object-fit: cover`), matching the 800px derivative the API
+generates so a plate never upscales on a 2× screen. Downscale with a good filter and a ~0.5px blur:
+the duotone blend amplifies aliasing on fine repeating detail such as a keyboard.
+
+```jsonc
+{ "name": "Bottom cover", "weightG": 156,
+  "photo": { "url": "/images/teardown/bottom_cover.webp", "srcset": "",
+             "alt": "Photographed during disassembly" } }
+```
+
+`srcset` is `""` because the fixture ships one width per photo, which is also why the fixture lane
+cannot cover the responsive path: only a real API response carries the width-keyed derivative map.
+`just test-e2e-live` closes that gap — it builds against the running `compose.e2e.yaml` backend
+(`PUBLIC_FEATURED_PRODUCT_ID=2`, the seeded Dell XPS 13) and runs
+[e2e/landing-live.spec.ts](e2e/landing-live.spec.ts), which asserts the page shows a live record
+rather than silently falling back, and that every plate carries a two-candidate `srcset` plus
+`sizes`. The root `just test-e2e-full-stack` runs it before the app's lane, on the same stack.
+
+The top-level `photos` array takes the assembled product the same way. Use photographs the project holds the rights to publish — the
+fixture is also production's fallback when the API is unreachable at build time, so anything here
+can end up on the live site. Contributor uploads are governed by the ToS grant and are not
+automatically clear for marketing surfaces.
+
+## Environment variables
+
+Public variables are read through `import.meta.env` and used by
+[src/config/public.ts](src/config/public.ts). Staging and production are built via Docker Compose
+(`compose.deploy.yaml`), which passes `PUBLIC_*` values as build args itself; `just build` and
+`just dev` are not part of that path. `just dev` falls back to hardcoded `127.0.0.1` dev-port
+defaults (matching `compose.dev.yaml`), overridable via the root `.env`; there is no
+`dev.compose.env`. `just build` is a local, non-Compose way to produce a production-mode build and
+sources `../deploy/env/prod.compose.env` directly; it has no staging equivalent.

+| `CI`       | Tightens Playwright reporting and retry behavior in CI                         |
+
+## Testing
+
+Unit tests live next to the code they cover as `*.test.ts`.
+
+```bash
+pnpm vitest run src/scripts/theme.test.ts
+pnpm vitest
+```
+
+CI runs `just test-ci` (Vitest with coverage, gated at 80% statements); plain `just test` does not
+evaluate that gate. `just ci` runs the full local CI pipeline (checks + `test-ci`), mirroring what
+CI does.
+
+E2E tests live in `e2e/`. By default, Playwright builds the site and starts a preview server when
+`BASE_URL` is not set. To run against the Docker stack instead:
+
+```bash
+BASE_URL=http://127.0.0.1:8013 pnpm run test:e2e
+```

+%% Regenerate the SVG (one-shot, not a www dependency):
+%%   pnpm dlx @mermaid-js/mermaid-cli -i method-flow.mmd -o method-flow.svg -b transparent
+%% then post-process the literal colours into page CSS variables and the font into
+%% inherit (see the sentinel table below), set role="group" + aria-label on the
+%% svg element, and drop the fixed max-width so the figure scales.
+%% Colour sentinels (Cyanotype, light values from www/src/styles/brand.css):
+%%   #1f4c96 to var(--color-primary)      (strokes, arrows)
+%%   #172637 to var(--color-on-surface)   (text)

+%%   #fefefe to transparent               (fills, label backgrounds)
+%%   rgb(0, 0, 0) to var(--color-on-surface)  (cluster/subgraph label text)
+%% Post-processing also inserts a <title> into each node <g> (native hover
+%% tooltip + screen-reader name): see the descriptions in
+%% MethodSteps.test.ts and the node ids method-flow-flowchart-<key>-N.
+%% (There is no narrow-screen variant: MethodSteps.astro is CSS-only markup
+%% that reflows at any width -- see its header comment. This .mmd only feeds
+%% the platform paper's figure.)
+%% IMPORTANT: the renderer must be able to *find* IBM Plex Sans, or mermaid
+%% measures labels with a fallback font and every multi-word label ends up
+%% clipped by a character once the page renders in Plex. Convert the woff2 in
+%% www/public/fonts to TTF into a dir, point FONTCONFIG_FILE at a fonts.conf
+%% listing it, run fc-cache -f, then render. Sanity check: the LR viewBox is

+// at 1024 -- and no CSS could raise them.

+// As markup the steps are real text: they scale with the reader's font size,

+  <div class="why-beats">

+      <h3 class="why-beat-label">Closed, and too slow</h3>
+      <p>
+        Circular-economy research depends on detailed product data: what things are made of, how
+        they come apart, which parts matter. That data is scarce, mostly closed, and slow to
+        produce. Producers hold it as proprietary, and small expert teams sampling by hand cannot
+        keep pace with what reaches the market.
+      </p>
+    </div>
+    <div class="why-beat">
+      <h3 class="why-beat-label">Downstream, at the point of failure</h3>
+      <p>
+        So Relab goes downstream, to the people who already open products: repairers, refurbishers,
+        dismantlers, recyclers. They meet products at the point of failure, a vantage that
+        captures as-failed composition, wear, and recoverability that as-designed specifications
+        never show.
+      </p>
+    </div>
+    <div class="why-beat">
+      <h3 class="why-beat-label">Value in both directions</h3>
+      {/* The previous version promised contributors "guidance on the most circular
+          R-strategy for what they are holding" in the present tense. Paper 1 is
+          explicit that this is not built: the architecture "support[s]
+          bidirectional knowledge exchange, enabling the *future* delivery of
+          sustainability metrics and repair guidance", and whether such returns
+          motivate contribution "is an assumption the pilot did not test". It was
+          also the last place the site implied Relab performs R-strategy analysis. */}
+      <p>
+        The exchange is meant to run both ways. Those observations feed back into the data
+        infrastructure research and design rely on, and the platform is built to return value to the
+        people who collect them, in composition insight and sustainability metrics. That return is
+        designed for, not yet delivered.
