CuratorAgents' Actions +# access is already set to `organization`; that setting is necessary but +# does not extend to public callers. +# +# Going private is not an option: https://interworks.github.io/curator-helm +# is the HelmRepository URL every site's HelmRelease pulls charts from, so +# taking the repo private takes GitHub Pages with it and breaks Flux +# reconcile fleet-wide. +# +# Checking out the private CuratorAgents repo *with a token* (as the +# `.themis-host` step below does) is fine from a public repo -- it's an +# authenticated API read, not a workflow reference. Only `uses:` is barred. +# +# KEEPING THIS IN SYNC +# This copy will drift.

Upstream +# uses mutable tags; this repo pins everywhere (helm-docs.yml, +# helm-test.yml, verify.yml, release.yaml) and REVIEW.md says to +# flag a mutable pin, so the vendored copy follows the local rule. +# Renovate keeps these current. +# +# KNOWN LIMITATION (upstream, tracked in InterWorks/CuratorAgents#389) +# The "Decide review gate" step short-circuits a re-review only when the +# prior review's API state is `APPROVED`.

A values key that changes shape, or a default +that changes value, reaches every site that bumps the chart. Review with +that blast radius in mind. + +Review as a principal Kubernetes / Helm engineer who is also fluent in how a +Laravel app boots: someone who guards the values interface, the rendered +manifest correctness, the database wiring, and the release automation. + +## CI environment notice (for the bot) + +This review runs in GitHub Actions with **no** Kubernetes cluster, **no** +`helm` binary, and **no** cluster credentials. Use only `Read`, `Grep`, +`Glob`, `Write`, and the allowlisted `git` / `gh` Bash commands. Do not try +to run `helm template`, `helm unittest`, `helm-docs`, or `kubectl` -- the +Helm Unit Tests and Check Helm Documentation workflows run those +independently on each PR. Reason about rendered output by reading the +templates. + +## Sibling repos: the contract this chart sits inside + +Two repos decide whether a change here is correct, and neither is visible +from this one. If they are checked out into `.themis-context/` for this run, +read them. If they are not, reason from what follows and raise a cross-repo +concern as a **question**, not as an asserted bug -- the decisive facts live +in a repo you cannot open. + +### `InterWorks/iac-interworks` -- the consumer + +The GitOps monorepo that deploys this chart. Per-site HelmReleases live under +`infrastructure///customer-workload//curator/helm/` +as `dev-helmrelease.yaml` / `qa-helmrelease.yaml` / `prod-helmrelease.yaml`, +or `--helmrelease.yaml` where a customer runs more than one +portal. `.templates/apps/curator/helm/` holds the stubs new sites are +generated from. + +Each HelmRelease pins a chart version and supplies its own values, so: + +- **What the fleet actually sets is what matters.** Before flagging a + default as wrong, check whether any site relies on it; before removing or + renaming a key, check who passes it. Example: every prod HelmRelease sets + `resources` explicitly, which is why an unreachable production sizing + branch in `curator.resources` went unnoticed for so long. +- **`.templates/` is the source of truth for new sites.** A values change + that leaves the template stub behind ships a broken new-site path. + +### `InterWorks/curator` -- the application + +The Winter/Laravel app this chart runs. The chart's job is to hand it a +correct environment, and the names have to match on both sides. + +- **The env contract lives in `docker/config/*.php`, not the repo-root + `config/*.php`.** The `docker/config` files are baked into the image and + are what read `CACHE_HOST`, `CACHE_PORT`, `CACHE_PREFIX`, `S3_BUCKET`, and + `S3_REGION`. The repo-root `config/*.php` tree reads a different set + (`DB_HOST`, `SENTRY_LARAVEL_DSN`, `AWS_*`, …). Checking a chart-rendered + env var against the wrong one of those two trees produces a confident + wrong answer in either direction. +- **`curator.config` keys override those same files.** Each key is written + into the config directory with `.php` appended, so a key that doesn't name + a real config file mounts a file nothing loads. +- **A new variable in `_env.tpl` is only useful if the app reads it**, and a + variable the app requires but the chart never sets fails at runtime, not at + render. Check both directions when a diff touches `_env.tpl`. +- **Probe paths are app routes.** `/ping` and `/healthz` are defined in the + application; a probe path change has to name a route that exists. + +## What CI already covers (do not flag) + +These run on every PR, independently of this review. Do not raise findings +these checks already enforce. + +- **Helm unit tests** (`.github/workflows/helm-test.yml`): `helm unittest + charts/curator`. A rendering failure or a broken assertion fails the PR, so + don't re-flag Go-template syntax errors or output that a green suite + already pins. + **Caveat, and it is a big one:** suites exist only for `deployment`, `hpa`, + `ingress`, `pdb`, `service`, and `serviceaccount`, and each suite exercises + one set of values. `cronjob.yaml`, `job-create-admin.yaml`, + `job-db-migrate.yaml`, `configmap.yaml`, `pvc.yaml`, the `externalsecrets-*` + and `mariadb-*` templates, and every conditional branch no suite sets + (`persistence.s3.enabled`, `autoscaling.enabled`, `maxscaleEndpoint`, + `mariadbNamespace`, `curator.config`, `envFromSecret`) are **unverified**. + Read those paths and reason about them yourself. +- **helm-docs check** (`.github/workflows/helm-docs.yml`): regenerates docs + and fails if `charts/curator/README.md` doesn't match. Don't flag a stale + README, and never ask for a hand-edit of it. Do flag a **missing `# --` + annotation** on a new value key -- helm-docs emits a blank description and + CI stays green (see *Values interface* below). +- **commitlint** (`.github/workflows/verify.yml`): every commit in the PR + must be a conventional commit. Don't flag commit-message *format*. Do flag + a wrong **type** or missing breaking-change marker, which commitlint can't + judge and which drives the released version (see *Release automation*). + +If a finding would duplicate one of these, drop it. + +There is **no** kubeconform, kube-linter, `helm lint`, or secret scanner in +this repo. Invalid Kubernetes fields, wrong `apiVersion`s, bad `nindent` +depth, and leaked credentials reach `main` unless a reviewer catches them. +Those are all fair -- and expected -- findings here. + +## Project conventions worth checking + +### Secrets (hard rule) + +No scanner runs on this repo, which makes the reviewer the only gate. + +- **Never commit plaintext secrets.** Credentials reach the pod through + `ExternalSecret` resources (`externalsecrets-db.yaml`, + `externalsecrets-admin.yaml`), a `secretKeyRef` to an operator-managed + secret, or `curator.envFromSecret`. Treat any password, token, DSN with + credentials, or connection string committed to `values.yaml`, + `test-values.yaml`, a template, or a test fixture as a must-fix finding -- + call it out first and unambiguously. A real Sentry DSN counts. + +### The values interface is a public API + +Every key in `values.yaml` is consumed by per-site HelmReleases in +`iac-interworks`. Flux renders the chart in-cluster with values that this +repo never sees, and a key that no longer exists renders silently to nothing +rather than erroring. + +- **Renaming, removing, or re-nesting a key is a breaking change.** It needs + `feat!:` or a `BREAKING CHANGE:` footer so release-please cuts a major, and + the PR should say what fleet-side change is required. Prefer keeping the + old key working (defaulting the new from the old) over a hard cutover. +- **Changing a default value changes every site that bumps the chart.** + Resource sizing, probe thresholds, `replicaCount`, PDB settings, backup + schedule/retention: a silent default change is a fleet-wide change. Flag + one that isn't called out in the PR. +- **New keys need a `# --` helm-docs annotation** immediately above them, and + a sensible default. Without the annotation, the generated README documents + the key with an empty description and the docs check still passes. +- **Keep `values.schema.json` and the templates in agreement.** The schema is + enforced at render, so adding a `required` key or narrowing an `enum` + breaks existing releases at reconcile time, not at review time. Also flag + the reverse drift: a template branching on a value the schema forbids is + dead code. (Live example: `curator.resources` in `_helpers.tpl` compares + `.Values.environment` to `"production"`, but the schema's enum is + `dev | qa | prod`, so the production sizing branch can never be taken.) + +### Database wiring (the repo's most-broken area) + +Three of the last five `fix:` commits were here (`#70` DB_HOST missing from +the CronJob, `#73` the last `mariadbEndpoint` fallback case, `#75` `-primary` +on the app's `db_host`). Give this area more scrutiny than its diff size +suggests. + +- **`DB_HOST` is set in four places and is not part of the shared env + block.** `_env.tpl`'s `env.environment` deliberately omits it; + `deployment.yaml` and `cronjob.yaml` set it from the `curatorDbEndpoint` + helper, while `job-create-admin.yaml` and `job-db-migrate.yaml` hand-roll + a `-primary.` value. Flag a change to + `curatorDbEndpoint` that isn't considered for all four consumers, and flag + any new pod spec that includes `env.environment` without also setting + `DB_HOST`. +- **The `-primary` suffix on the write path is deliberate, not a typo.** + Migration and admin-creation jobs must hit the primary; routing them at a + replica gives read-only failures. Don't "simplify" those two to the shared + helper, and do flag a new write-path workload that resolves to the + replica-capable endpoint. +- **`curatorDbEndpoint` resolves in a fixed order**: maxscale (with + namespace) -> `mariadbEndpoint` (with namespace) -> `mariadbEndpoint` + (release namespace) -> `mariadbName` (release namespace). A new branch or + a reordering changes which host live sites resolve to. Check each arm + renders a fully-qualified, correct host, and that a value combination the + branches don't cover can't fall through to a wrong default. + +### Release automation (release-please owns the version) + +- **Never hand-edit** `charts/curator/Chart.yaml`'s `version`, + `charts/curator/CHANGELOG.md`, `.release-please-manifest.json`, or the + README's version badge. release-please owns all four, and a manual bump + desynchronizes the manifest from the tags. Flag any human PR that touches + them. +- **`appVersion` is hand-managed** (release-please does not touch it) and + names the Curator application release the chart defaults to. Renovate keeps + `image.tag`'s digest current on its own, so the two don't move in lockstep; + what's worth flagging is an `appVersion` bump in a PR that changes nothing + else about the app defaults, or a human `image.tag` change that leaves a + now-wrong `appVersion` behind. +- **The commit type is the version bump.** `fix:` -> patch, `feat:` -> + minor, `feat!:` / `BREAKING CHANGE:` -> major. A values-interface change + labeled `fix:` ships a breaking change as a patch to the whole fleet. + Flag the mislabel, not the message wording. + +### Image pins + +- `image.tag` is digest-pinned (`latest@sha256:...`) and Renovate-managed. + Flag a hand-edit that **unpins** it (drops the `@sha256:` digest), points + it at a different repository/registry, or moves it **backward** -- Renovate + only moves pins forward, so a backward move in a human PR is most likely an + accidental regression. A deliberate, stated rollback is fine. +- `_image-tag-check.tpl` fails the render for tags below the `2025.5.1` + minimum, and skips the check for tags containing `dev` or `latest`. + Changing that guard's threshold or its escape hatches is a fleet-visible + change; flag it if the PR doesn't say why. + +### Manifest correctness + +Nothing validates rendered output against the Kubernetes API here, so read +for it: + +- Correct `apiVersion` / `kind` pairs for the cluster's Kubernetes version, + and for the mariadb-operator and External Secrets CRDs. +- `nindent` depth matching the surrounding block. An off-by-two indent + produces valid YAML with fields on the wrong parent, which no test catches. +- Labels and selectors from `curator.labels` / `curator.selectorLabels` -- + changing a selector on an existing Deployment is an immutable-field error + at upgrade time, not a render error. +- Probe changes: `/ping` is deliberately dependency-free on liveness and + startup, and `/healthz` (DB-aware) is deliberately readiness-only. Flag a + change that puts a database-aware endpoint on the liveness probe -- that + restarts every pod at once during a DB blip instead of pulling them from + the Service. + +### Tests + +- **A new or changed template should come with a suite** in + `charts/curator/tests/`, especially for the templates listed as uncovered + above. A bug fix should come with a test that would have failed before it. +- **Test files must be named `*_test.yaml`.** The discovery glob is + `tests/*_test.yaml`; anything else is silently ignored and never runs (this + has already happened once in this repo). Flag a suite added under any other + name. + +### Workflows + +- Third-party actions are **SHA-pinned with a version comment**; flag one + pinned to a mutable tag or left unpinned. +- Jobs run on the self-hosted pools (`us-east-2-development`, + `us-east-2-development-docker`) and install tooling with `mise` from + `mise.toml`. Don't flag the self-hosted runner choice. Do flag a workflow + that installs `helm`, `helm-docs`, or `node` at a version other than the + one `mise.toml` pins -- a generator version mismatch breaks the docs check. + +## What is *not* a finding + +- Style nits a linter or formatter would (or wouldn't) flag, and YAML + formatting preferences in the chart templates. +- Speculative concerns -- "what if someday". +- "You could also consider..." suggestions. +- Naming preferences when the existing name is reasonable. +- Requests for comments unless the *why* is genuinely non-obvious. +- The generated `charts/curator/README.md` diff itself, when it matches the + values change in the same PR. That file is machine-written; review the + `values.yaml` change instead. +- Missing tests on a docs-only, comment-only, or CI-only change. +- The self-hosted runner pools, including a SHA-pinned third-party action + running on one; that tradeoff is accepted here. + +## State facts, not intent + +You can see the diff; you cannot see *why* the author made it. Describe what +the change does and let the author confirm the why -- never assert intent as +fact. + +- Say *"this drops the `mariadbNamespace` arm from `curatorDbEndpoint`, so + external-namespace sites now resolve to the release namespace -- is that + intended?"*, not *"this correctly simplifies the endpoint helper"* **or** + *"this breaks external-namespace sites."* You don't know which -- name the + fact and ask. +- Don't manufacture a rationale to approve a questionable change, and don't + invent a motive to condemn one. +- On a re-review, if new commits change your read, state what *factually* + changed since the prior version; don't retroactively re-narrate the + author's intent or contradict a verdict you stated before without saying + what moved. + +## Bar for a must-fix finding + +Themis runs in **comment-only** mode here: every review is a non-blocking +`COMMENT` -- it never approves or requests changes, so it never blocks a PR. +Call the issues below out prominently as must-fix. The bar is *"this is +wrong"*, not *"this could be better"*: + +- A plaintext secret or credential anywhere in the repo. +- A values key renamed, removed, or re-nested without a breaking-change + marker, or a changed default the PR doesn't call out. +- A `values.schema.json` change that would fail an existing site's render, or + schema/template drift that makes a branch unreachable. +- A database-wiring change that leaves the four `DB_HOST` consumers + inconsistent, or routes a write-path workload off `-primary`. +- A hand-edit of `Chart.yaml`'s `version`, `CHANGELOG.md`, or + `.release-please-manifest.json`, or a commit type that ships a breaking + change as a patch. +- An unpinned, redirected, or backward-moved `image.tag` without a stated + rollback. +- A rendered manifest that is invalid or wrong: bad `apiVersion`/`kind`, + misindented block, mutated Deployment selector, DB-aware liveness probe. +- A test suite added under a filename that helm-unittest won't discover. +- A bug or incorrect logic in a template helper, workflow, or script. +- A documented or load-bearing invariant the diff violates. + +If you don't find one of those, say so in one line -- don't pad the comment +with style nits or "you could also consider" suggestions. + +## Closing line: feedback on the review + +After the findings -- whether or not you raised any -- end every review with +this exact one-line invitation, so a reader who thinks the review missed the +mark has an easy way to flag it: + +> _Didn't do a good job on this review? Add the `claude_bad` label to this PR so the team can flag it for improvement._ + +Keep it to that single line, as the last thing in the comment.
