Problem

Scope item: N/A — focused documentation, repository-template, and client-contract alignment.

Silo's README had gradually become a product overview, installation guide, operator manual, distributed-deployment reference, tuning guide, and contribution entry point at the same time. The information was useful, but the reading order made it harder for newcomers to understand the product and start safely, while experienced operators had to work through a long landing page to find deployment details.

Some guidance had also drifted from the current implementation, Compose configuration, and CI toolchain. The contribution flow duplicated policy across several files and did not consistently guide contributors from setup through evidence, AI disclosure, and review.

Approach

This change introduces a clearer, progressive flow:

  1. Explain what Silo is, who it serves, and its current pre-release/build status.
  2. Provide a concise, secure default Docker quick start.
  3. Route advanced deployment and operational work to a dedicated Docker guide.
  4. Route source development, API details, contribution policy, and AI guidance to their canonical documents.
  5. Keep issue and pull-request templates aligned with those expectations.

The README is reduced from 439 lines to about 210 lines without discarding the detailed operational material. That material now lives in docs/wiki/deployment/docker.md, while the detailed proxy-delivery contract is placed with the Downloads API documentation.

The contribution documents retain the project's substantive rules while improving their order, terminology, command accuracy, and separation of concerns. AI policy remains explicit and is linked from the shorter contribution flow rather than being inconsistently repeated.

The dynamic release badge is intentionally retained so it will become active when maintainers select the first release. The README now distinguishes ordered build-N images and commit identifiers from future SemVer releases in the meantime.

Advantages

  • Gives prospective users a faster, more professional explanation of Silo and its capabilities.
  • Makes the default installation path easier to follow while moving advanced choices out of the critical path.
  • Preserves operational depth with clearer guidance for secrets, TLS exposure, SQLite persistence, GPU access, external services, migrations, backups, updates, and rollback.
  • Aligns documentation with the current code, Compose behavior, supported media types, server roles, Jellyfin compatibility defaults, pnpm toolchain, and CI checks.
  • Reduces duplicated guidance and gives each audience a clearer canonical destination.
  • Makes contribution evidence, AI disclosure, issue intake, and review expectations consistent across repository templates and policy documents.
  • Lowers future maintenance cost because product, operator, developer, API, and contribution guidance are no longer competing within one document.

Scope and risk

This is primarily a documentation and repository-template change. It also adds the existing API's required proxy_delivery boolean to the maintained TypeScript response interface so the client contract matches the server and new documentation. It does not change runtime logic, Compose services, migrations, versions, releases, tags, or deployment configuration.

Contributor ownership

@blurbery led and owns this documentation redesign: defining the audience and desired reading flow, identifying presentation and policy requirements, reviewing the original material and the rendered result on the fork, making the final editorial decisions, and approving the complete submission. This included the decisions to preserve the release badge, retain the contribution rules that matter, and move detail into focused documents without losing it.

Most product and editorial judgment, including the final review, came from @blurbery. AI assistance was used for implementation support, repository auditing, drafting, consistency checks, and adversarial review.

Testing

  • git diff --check origin/main...HEAD — passed.
  • make verify-local-paths — passed.
  • Parsed both changed GitHub issue-form YAML files and checked their structure — passed.
  • Resolved changed local Markdown links and anchors — passed.
  • Parsed the new wiki front matter and checked Markdown fences — passed.
  • Compared the original 11 documentation/template paths with the version reviewed on blurbery/silo-server:main; the only pre-review follow-up was the explicitly requested top-level Support Silo link to the unchanged sponsorship section.
  • Asserted that the TypeScript DownloadCapability field matches the required server response and that the revised disclosure, port, and tuning guidance contains the reviewed constraints — passed.
  • Reviewed the final scope and credential/local-path patterns — no runtime-logic changes, generated files, local paths, or credentials found.
  • Initial upstream CI before the review fixes: Go, Web, and Docs hygiene passed.

The full Web suite was not rerun locally because this clean checkout has no installed Web dependencies and its ambient Node/pnpm versions differ from the repository-pinned CI toolchain. Upstream CI is the authoritative post-review integration gate. The first review-fix run passed for commit 99ba175: Go, Web, and Docs hygiene. The final one-line disclosure clarification in 34a38e3 passed the same gates.

AI Disclosure

  • Tool(s): OpenAI Codex (desktop)
  • Model(s): GPT-5 (Codex; the exact deployment identifier was not exposed to the agent in this session)
  • Involvement: AI-assisted. Codex helped audit the repository against the documentation, implement the approved structure, check cross-document consistency, and prepare the contribution under @blurbery's direction and review.
  • Adversarial review: Three independent Codex review passes checked factual accuracy against the code, Compose files, CI, and Make targets; preservation and relocation of existing guidance; command safety; links and forms; and contribution-policy integrity. CodeRabbit initially raised four actionable threads plus one security nit, representing four underlying issues: disclosure-field clarity, the missing TypeScript proxy_delivery field, configurable health-check ports, and least-privilege external PostgreSQL tuning. All were validated and fixed in 99ba175; the two proxy-delivery threads share the same contract fix. After those fixes, its final-tree review found one additional minor template issue: the prompt omitted review scope and method. That was fixed in 34a38e3. The release badge's pre-release state was reviewed and intentionally retained pending the maintainers' first release selection.

Checklist

  • The complete diff received independent adversarial review, summarized above.
  • CodeRabbit's valid findings were addressed and documented.
  • Documentation-specific validation, focused contract assertions, and repository path checks pass.
  • The rendered fork version was reviewed and approved by @blurbery.
  • The change remains focused on documentation flow and the directly related client-contract alignment, with no production behavior change.
  • Post-review upstream CI passed for commit 99ba175: Go, Web, and Docs hygiene.
  • Final upstream CI passed for commit 34a38e3: Go, Web, and Docs hygiene.

Summary by CodeRabbit

The capability response and frontend interface document proxy availability. The guide defines proxy routes, redirects, direct responses, relay behavior, bandwidth-limit constraints, and unchanged legacy routes.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to d9383

The PR reorganizes documentation and contribution guidance and aligns a typed download response contract without changing runtime logic. A required issue-form review field is still missing, and two localized examples can mislead contributors or fail when copied literally; these bounded issues should be fixed or explicitly accepted before merge.

321-326: 🔒 Security & Privacy | 🔵 Trivial

Add a least-privilege warning for external auto-tuning.

- docker.md: give a real pg_dump backup (live data-dir copies are torn),

Do not require host database services for the Compose workflow.

The documented local workflow starts PostgreSQL and Redis with docker compose up -d postgres redis at Lines [33]-[34]. The bullets at Lines [13]-[14] are therefore optional prerequisites for external services, not prerequisites for this workflow. Remove them from the default list or label them as alternatives.

Pushed 0f6bbcaf on top of this branch (rebased on main) with the review fixes and a prose pass:

Corrections

  • docs/downloads-api.md §4.11: proxy_delivery: true means the proxy routes are mounted, not that a request redirects; artifact relay applies to /downloads/{id}/file only.
  • docs/wiki/deployment/docker.md: real pg_dump backup (live data-dir copies are torn), restart postgres silo together, long migrations vs. the container healthcheck, --migrate-status / --migrate-down-to, compat ports on by default.
  • AGENTS.md: Related issue wording aligned with the template; pre-PR gate points at CONTRIBUTING.
  • .env.example: POSTGRES_PASSWORD commented out so the quick-start append is the only definition.
  • Issue forms: dropped the required Adversarial-review field; restored the fabricated-report warning.
  • Changelog entry for proxy delivery (feat(downloads): distribute preparation and delivery #607).

Consolidation

  • One pre-submission gate, one quick start, one go.work paragraph, one disclosure block wording.

* fix(watchsync): redact undeclared connection secrets

Connection config fields absent from a schema's declared sets are classified
as secrets fail-closed, but the fault-redaction list collected only declared
secret fields. A plugin echoing such a value in a fault returned it in the
clear. Redact every flattened secret value instead.

* fix(audiobooks): gate enrichment on identity, not cover art

The audiobook enrichment sweep had been permanently idle. Eligibility
required an empty poster_path, but the scanner extracts embedded cover
art from audiobook files, so every item had a poster before enrichment
ever looked at it. Cover presence says nothing about whether an item was
identified, and using it as the "already enriched" proxy meant the
predicate matched nothing.

On production this selected 0 rows while 5,712 audiobooks held no
provider ID at all -- 5,710 of them carrying a scanner-supplied poster.
The metadata providers had enriched 42 items in total; the 235,780 ASINs
in the library came from file scan, not from a provider. The 5-minute
trigger kept firing and finding nothing, so the gap could never drain.

Key both claimBatch and HasPendingItems on the absence of any row in
media_item_provider_ids instead. Sized against production this makes
5,682 items eligible rather than the 240,857 that dropping the poster
clause alone would have queued against Audible.

last_refreshed IS NULL is retained as the retry bound, and it is load
bearing: enrichItem stamps it on a clean no-match but deliberately
withholds it on provider error, so unmatchable items are attempted once
while transient failures still come back.

Adds DB-backed tests for both predicates, including the exact row the
regression hid (cover art present, no identity). Both fail against the
old predicate and pass against the new one. Neither query had any test
coverage before, which is how this survived.

* fix(metadata): require a credible title match before accepting a provider result

Enrichment took results[0] from every search provider unconditionally.
Search backends rank by their own relevance and answer nearly every
query with something, so a provider's best guess became the item's
permanent identity -- and enrichment stamps last_refreshed on success
and never revisits, so a wrong acceptance is a permanent mislabel:
another book's cover, overview and narrator.

Measured rather than assumed. Twenty unidentified production audiobooks
were queried against the iTunes audiobook search: 19 returned a result
and roughly a quarter of those top hits were wrong -- either a different
volume of the right series ("The OP MC 8: God of Winning" answered by
"God of Winning: The OP MC, Book 1") or an unrelated title sharing one
common word ("Star Force Origins" answered by "The Achilles Trap").

Adds metadata.BestMatch, which scores candidates against the title we
hold on disk and returns nothing when none is credible -- callers treat
that as a no-match instead of falling back to the top row. Scoring is
word-set overlap (Dice) because the differences that matter are whole
words added or dropped: an author prefix, a series parenthetical, an
"(Unabridged)" suffix. A volume disagreement is fatal regardless of
overlap, since same-series wrong-volume pairs share nearly every word.

Wired into all three call sites that had the flaw: audiobooks, ebooks
and manga. Ebooks scores against item.Title rather than the outgoing
query, which is deliberately cleaned before it is sent.

Calibrated on the real probe pairs, kept as the test fixtures: correct
matches score >= 0.88, wrong ones <= 0.44, threshold 0.50. A test
asserts the two populations stay separated so a future tweak that
narrows the gap fails here rather than in production.

Three ebook fixtures needed a title on their SearchResult. They were
passing a result with no name at all, which the gate rejects; one of
them (SkipsProviderIDOwnedByAnotherItem) would otherwise have kept
passing for the wrong reason, never reaching the ownership check it
exists to cover.

* fix(metadata): drop stopwords when scoring title similarity

Validating the gate against the full 20-title production probe caught a
false accept it should have blocked. "All the Lies 1-3 - All the Lies:
The Complete Trilogy" was matched to "The Sentinel: The Complete Jane
Harper Trilogy: The Jane Harper Trilogy, Books 1-3" at 0.56, over the
0.50 threshold.

Both are "Books 1-3" boxed sets of unrelated series, and the score came
almost entirely from words that carry no identity: "the" three times,
plus "complete", "trilogy" and the 1 and 3 of the volume range. Neither
title's actual subject contributed. Excluding a small stopword set takes
the pair to 0.42, where it belongs, and leaves every correct match in
the sample above threshold.

The exclusion is skipped when it would leave fewer than two words to
compare, so titles that are mostly stopwords ("A Man in Full") still
have something to match on rather than scoring 0 against everything.

Rescored against all 20 probe pairs: 12 accepted, 7 rejected, 1 had no
answer. Every rejection is a genuine mismatch -- two wrong-volume pairs
of the right series, two unrelated titles, this boxed set, a bare common
noun, and a same-series different-book pair. Blind results[0] acceptance
would have taken 19 of these, roughly 6 of them wrong.

Fixtures now carry the untruncated provider strings, since the truncated
ones scored differently from what production actually returns -- which
is why the first version of this test passed while the real pair failed.

* fix(ebooks): search the bare title and disambiguate volumes after the search

cleanEbookSearchTitle unwrapped a trailing series marker -- brackets
removed, words kept -- so "Icarus (Realm Book 3)" went out as "Icarus
Realm Book 3". The reasoning was that the volume number is what tells
sibling volumes apart, and dropping it would make every entry in a
series search as the bare series name and collapse onto one work.

That held only while enrichment accepted results[0] blindly. It is no
longer true: metadata.BestMatch scores candidates against the raw
item.Title, which still carries "(Realm Book 3)", and treats a volume
disagreement as fatal. The disambiguator never needed to be in the
query -- it needed to be in the check, and now it is.

Meanwhile the unwrapped form was not disambiguating the search, it was
breaking it. "Realm Book 3" is retail furniture that no provider
catalogue indexes, so the query matched nothing at all.

Measured on 40 parked no_match ebooks that carry a series parenthetical,
with both query forms produced by this function and both result sets
scored by the real gate:

  what the server sends today : Open Library answered  3, accepted  0
  after this change           : Open Library answered 29, accepted 14

14 recovered, 0 lost. The gap between 29 answered and 14 accepted is the
scoring gate rejecting results that came back but are not the book --
15 wrong identities that blind results[0] would have stamped
permanently.

Scope, so the number is not read as more than it is: 23,802 of the
110,556 parked no_match ebooks (21.5%) carry a trailing series
parenthetical, so this reaches about a fifth of the backlog. The other
78.5% fail for reasons this does not touch.

* fix(metadata): make title normalisation Unicode-aware

Found reviewing this branch's own diff. normaliseTitle stripped via
[^a-z0-9] after lowercasing, which is ASCII-only. Every non-Latin title
reduced to the empty string, so TitleScore returned 0 and BestMatch
rejected it -- including against an identical title. "進撃の巨人" scored
0.00 against itself. Accented Latin fared little better:
"Blåbærsyltetøy" became "bl b rsyltet y".

That would have been a hard regression for non-English content, and a
quiet one: those items previously matched by accident, because
results[0] was accepted without any check at all. Manga is the obvious
exposure, but the library carries Danish and Norwegian ebooks too.

Strips [^\p{L}\p{N}]+ instead, so letters and digits in any script
survive. Tests cover Japanese, Russian and Danish titles matching
themselves and rejecting different titles in the same script.

For scripts that do not space their words, a whole title normalises to
one token, so Dice gives 1 on an exact match and 0 otherwise, with
containment carrying near-misses. Coarse, but correct, and strictly
better than what it replaces. minContainmentLen stays byte-measured,
now documented as deliberate: for ASCII it is the character count the
threshold was calibrated on, and for multi-byte scripts it is more
permissive, which is right because a four-character CJK title is
specific in a way that "Bitcoin" is not.

* fix(metadata): fold numerals, break ties on year, and stop cross-provider ID mixing

Follow-ups to the match gate, each closing a hole the first pass left.

Numeral folding. Providers and rippers disagree freely on form:
"Slaughterhouse 5" against "Slaughterhouse-Five" scored exactly at the
threshold and matched only by luck, and a "Part II" volume never agreed
with "Part 2" -- which the volume rule then read as a disagreement and
rejected outright. Spelled and Roman numerals now fold to digits before
scoring, capped at 30 so single letters like "X" and "I" stay letters
("Malcolm X" must not become "Malcolm 10").

Year as a tiebreak, never a gate. For books a year gap is weak evidence:
an audiobook edition of a 1994 novel is routinely dated by its recording
decades later, so rejecting on it would discard correct matches
wholesale. It only decides between candidates already tied on title.

Cross-provider agreement. Each provider was scored independently and
every accepted match was merged into one ID map, so two providers could
each clear the bar while naming different books and leave the item
holding IDs for two works -- worse than either answer alone, because
afterwards the wrong ID is indistinguishable from the right one. The
first accepted title is now the reference and later providers must agree
with it.

Ownership guard for audiobooks and manga. FindContentIDByProviderIDs
appeared three times in the ebook enricher and nowhere in the other two,
so sibling volumes resolving to one provider work all claimed the same
ID with nothing noticing -- the exact collapse the ebook code guards
against, and manga is the most exposed, with series running to dozens of
near-identical titles. Ported including the "don't claim an ID we
couldn't verify is free" path that retries rather than stamping
terminally.

Rejections now log at Info. During a backlog drain the rejection rate is
what separates "threshold too strict" from "providers answering badly",
and that cannot be read from a log level nobody enables.

The threshold is overridable via SILO_METADATA_MATCH_MIN_SCORE so it can
be retuned against a live library without a rebuild; out-of-range values
are ignored rather than obeyed, since a typo'd 0 would accept everything.

Acceptance is now strictly above the threshold rather than at it: a
two-word title sharing one word with a two-word candidate scores exactly
0.5, which is the weakest possible evidence, not a match. Nothing correct
is lost -- the worst true match in the calibration sample scores 0.86.

* fix(metadata): verify the author after fetching, not just the title

Title scoring cannot separate two different books that share a title,
and for books that is not a rare edge -- generic titles recur constantly
across authors, so the gate would accept the wrong one on nothing more
than a title agreement.

The obvious fix is unavailable: the plugin contract's SearchResult
carries title, year, overview, image and provider IDs, and no author at
all. Checking it at search time would mean changing the SDK proto and
every plugin implementing it.

It is available one step later. Enrichment already calls GetMetadata on
the accepted match, and MetadataResult.People carries the credits, so
the author is verified after the fetch: a positive contradiction is
recorded as a no-match rather than written. Wired into all three
enrichers.

Absence is never disagreement. An item with no author, or a provider
returning no credits, passes -- most of this library is missing one or
the other, and treating that as a conflict would reject far more good
matches than bad ones. Only a name that actively contradicts rejects.

Name comparison allows for how the same person gets credited: surname
plus first initial (which survives middle names and
initials-vs-full-first-name), the "King, Stephen" reversal, and one form
contained in another ("Iain Banks" within "Iain M. Banks"). Non-author
credits are ignored, so a narrator neither confirms nor contradicts
authorship.

Diacritics ARE folded for names and deliberately are NOT for titles.
Providers transliterate people inconsistently -- "Émile Zola" and "Emile
Zola" are one person, and without folding they disagreed on their first
initial and the match was rejected. Titles are different: "Blåbær" and
"Blabaer" are not reliably the same work, and folding there would erase
a real distinction.

* feat(audiobooks): give enrichment its own state table

Audiobook enrichment recorded its outcome in exactly one place:
media_items.last_refreshed. That stamp had to mean "matched",
"genuinely unmatchable" and "the provider was down that minute" all at
once, so a bad afternoon on a provider burned the item exactly as
terminally as a real no-match, with no attempt count, no error class and
no backoff. Ebooks have ebook_enrichment_state and manga has
manga_enrichment_state; audiobooks had nothing.

The new table sits deliberately between those two. It is not the full
ebook lease queue: audiobook sweeps run from a single task-manager
goroutine and claimBatch takes no row locks, so claim_token/lease_until
would be machinery with nothing to coordinate. It is more than the manga
table, which counts failures and nothing else.

last_refreshed stays authoritative for eligibility, so the migration
changes no behaviour by itself. What changes is that the sweep now skips
items parked for a later retry, and records why each item is where it
is.

Failures are classified, because the distinction is the one the ebook
backlog lost: 90,721 rows there carry outcome='no_match' with attempts=0
and an empty error class, which is why a rate-limited sweep on
2026-07-20 is indistinguishable from 90,721 genuine misses. Here a
failure records a class and parks a retry WITHOUT setting an outcome --
it has not reached a terminal state. Rate limiting backs off hardest
(retrying into a closed window is what turns a throttle into a backlog)
and permanent failures park far out rather than never, since "permanent"
is a classification and classifications are sometimes wrong.

attempts always increments, including on terminal rows, so "never tried"
and "tried and gave up" stay distinguishable.

Bookkeeping never fails the enrichment it describes: a state write error
is logged and swallowed, since last_refreshed remains the authoritative
signal and losing a state row costs reporting detail, not correctness.

Seven DB-backed tests, run against a migrated throwaway Postgres rather
than assumed: the two covering the parked-retry predicate fail with the
predicate removed and pass with it, so they guard something real.

* fix(metadata): close four review findings on the match gate

All four verified by reproduction before fixing; none were false
positives.

NFC-normalise before tokenising. A decomposed accent (e + U+0301) is a
combining mark to the punctuation strip and vanished, while the composed
spelling kept its letter, so two byte-level spellings of "Café" scored 0
against each other and an identical title was rejected.

A wrong-volume primary can no longer be rescued by its alias. Aliases
are often the bare series name; "Dungeon In My Closet, Book 5" was
accepted for a volume-2 item through its generic "Dungeon In My Closet"
alias, persisting IDs for the wrong book. A volume stated on the primary
title that contradicts the item's now disqualifies the whole result.

The ebook series-noise test requires volume syntax, not a marker word.
Bare "book" matched anywhere, so "(The Book Thief)" -- a title, not
furniture -- was stripped from the query. The parenthetical is now only
dropped for "Book 4" / "#3" / bare-number / bare-year shapes.

The scheduler-mirror test asserts its own fixture was claimed rather
than that the claimed set is non-empty, which unrelated rows in a shared
test database could satisfy.

Also consolidates the two identical providerIDOwnerLookup interfaces
(ebooks, manga) onto metadata.ProviderIDOwnerLookup per the repo rule
against duplicated contracts.

* fix(audiobooks): make failure recording atomic and UTF-8 safe

Two review findings on the state store, both real.

RecordFailure was two round trips: an upsert incrementing attempts, then
an update parking next_attempt_at. Anything landing between them -- a
cancelled context, a dropped connection, a concurrent RecordOutcome on
the same row -- left the item with an incremented attempts count but no
backoff at all, immediately re-claimable against the very provider that
just failed; or let a terminal outcome be resurrected as a parked retry.
Now a single upsert computes min(step * attempts, cap) on the
post-increment attempts value inside the statement, so there is no
partial-write window rather than a transaction hiding one. retryAfterFor
remains as the Go mirror of the same math, built on shared
backoffParams so the two cannot drift.

The cause truncation cut at a byte index, which can split a multi-byte
rune; Postgres rejects invalid UTF-8, which would have silently failed
the entire failure/backoff write for that call -- the exact no-backoff
state the atomicity fix removes. Truncation now passes through
strings.ToValidUTF8, with a DB-backed regression test whose 500-byte
boundary lands mid-rune.

Also reverts four pre-existing files (abs/, podcastfeed/) that an
overly broad gofmt -w swept into the branch; they are not part of this
change.

* fix(metadata): harden book enrichment admission

Part of #510

* fix(ebooks): count real no_match cycles and escalate their retry horizon

Complete() zeroed attempts on every outcome, so a row bulk-stamped
no_match without a lookup was indistinguishable from one that failed
five real attempts, and every no_match returned on the same flat 30-day
horizon forever — permanently unmatchable titles (cover-scan artifacts,
bare file numbers) consumed the same daily recycler quota as books that
were never actually tried.

- failures now counts consecutive no_match completions (success resets)
- the no_match horizon doubles per prior failure, capped at 8x:
  30d, 60d, 120d, 240d
- retail edition suffixes are stripped from search queries — anything
  ending in Edition(s)/Classics, Kindle Single, A Novel — the same
  reasoning as the series-marker rule: providers index the work, not
  the storefront packaging. (Illustrated)/(Annotated) still survive.

* fix(ebooks): promote ebooks resolved from complete local metadata

enrichClaimedItem returned EnrichmentOutcomeSuccess for items whose
embedded metadata already satisfied every field enrichment would fetch,
without ever running the status promotion. That was the only terminal
outcome to skip it: no_match, author-mismatch, and provider success all
reach stampLastRefreshed, the sole writer of status 'pending' -> 'matched'.

Those items therefore kept media_items.status = 'pending' permanently and
were counted by the library "unmatched" tile. On prod this is 43,653 of
the 44,014 reported unmatched items (99.2%) — every one of them with
outcome='success', last_refreshed IS NULL, matched_at IS NULL, and title,
author, overview and cover all populated. Rescanning cannot clear them,
because the short-circuit fires again and the queue re-parks the row.

last_refreshed is deliberately left untouched: it gates the admin
quick-refresh sweep, and no provider was consulted here, so these items
must stay eligible for a later refresh that could attach a provider
identity.

* feat(auth): scoped API keys and admin user API hygiene

Scoped API keys: an sa_ key may now carry an allowlist of scopes
(admin:users, admin:access-groups:read). A scoped key is refused on every
route its scopes do not name — including the Jellyfin-compat surface and
plugin access — so an integration credential (e.g. a billing system doing
user provisioning) no longer needs a full-power admin key. Empty scopes
keep the existing behavior. Scopes narrow, never grant: role checks still
apply to the owning user.

Admin user API hygiene:
- POST /admin/users maps a duplicate username/email to 409 duplicate
  instead of an opaque 500, so clients can distinguish a lost-response
  retry from a genuine server error.
- DELETE /admin/users/{id} maps a missing user to 404, making terminate
  retries idempotent from the client's point of view.
- POST /admin/users accepts access_group_id (the repository already
  supported it), removing the create-then-update window where a new user
  briefly sat under the default access group.

* feat(access): inherit/override user policy resolution

User policy fields move from "strictest of user and group wins" to
inherit/override: NULL on the user row means "inherit the access group's
value"; a set value is an explicit per-user override that replaces the
group value in either direction — grant or restrict. A group saying "no
downloads" no longer forbids granting downloads to one of its members,
and a member's cap above the group's now wins instead of being clamped.

- users: max_streams, max_transcodes, max_playback_quality,
  transcode_allowed, audio_transcode_allowed, download_allowed,
  download_transcode_allowed, library_ids become nullable (NULL =
  inherit); new nullable requests_allowed. Numeric 0 becomes an explicit
  "unlimited" override instead of a delegation sentinel.
- access_groups: gain transcode_allowed / audio_transcode_allowed so
  every user field has a group value to inherit.
- resolution collapses to effective = user.field ?? group.field ??
  permissive no-group default; permissions keep the allowed_permissions
  intersection mask. All enforcement reads go through the resolver,
  including the previously raw fallbacks (items/sections/libraries
  library scope, legacy permission middleware, /auth/me and login
  download_allowed, requests gate — which now honors a user override).
- downloads package no longer launders effective policy back into
  models.User; checks take a resolved PolicyUser.
- admin user API: PUT accepts explicit null per policy field to clear an
  override back to inherit (tri-state), GET reports stored overrides
  (null = inherited) plus a resolved effective_policy block; access-group
  API carries the two new gates.
- migration maps old delegate values (0 / '' / true) to NULL and keeps
  restrictive values as overrides, so existing behavior is preserved
  except the deliberate cap-above-group change.
- web admin: user forms get per-field Inherit/Override controls showing
  the inherited effective value, saves send explicit null for inherited
  fields (no more silent pinning on save), the user overview shows
  effective values with override provenance, and the access-group editor
  gains the video/audio transcoding toggles.

* fix(access): review fixes for inherit/override reporting

Findings from the adversarial review of c025a6e6:

- An explicit empty library_ids override ([] = no libraries) round-trips
  as [] in admin responses instead of collapsing to null (inherit), so an
  admin open+save no longer silently deletes a deny-all override.
- effective_policy now fails closed: a failed access-group lookup returns
  500 instead of silently rendering a group-restricted user against the
  permissive no-group default.
- Migration maps a pre-existing NULL download gate (the columns were
  always nullable) to inherit instead of inventing an explicit deny
  override, and the down block documents its inherent lossiness for
  explicit permissive overrides.
- web: updating an access group invalidates user queries so effective
  values and inherit hints refresh; changing the group inside the user
  edit dialog degrades inherit hints to generic labels instead of showing
  the old group's values; the invitation form labels null library scope
  as inherit-from-group rather than 'All libraries'.

* fix(web): refine featured hero metadata

* fix(access): close scoped-key escalation and policy review findings

Scoped API keys: an admin:users key could create or take over an admin
account and log in for an unscoped JWT. Scoped actors may no longer
assign the admin role or change credentials on an existing admin.
Self-service POST /api/v1/api-keys now honours `scopes` instead of
silently dropping them, and GET /api/v1/api-keys/scopes advertises
the catalog for feature detection.

Policy resolution: download_transcode_allowed was the one column whose
old default was false, so the migration froze every account as an
explicit deny; it now maps false to inherit, NoGroupPolicy matches the
old default, and Down restores the correct default. Legacy negative
caps map to inherit instead of unlimited. Ungrouped users no longer
query the group store, home sections and item filters fail closed on
a policy error like /libraries, the legacy metadata gate resolves
inherited libraries, and the requests service no longer has a dead
group-only fallback.

Web admin: inherit hints follow the selected group on both tabs and on
the create form, Override no longer seeds 0 (= unlimited), an empty
limit box cannot be saved as 0, the effective panel shows the
group-intersected permissions and the audio-transcode row, and the
access-group copy describes inherit/override.

Cleanups: one tri-state decoder, generic clonePtr, shared cap
validator, table-driven user Update, single policy field table in the
web form, orphaned UserTranscodeLimitField removed, unused
OverrideSources removed.

- feature-changelog: add the missing entry for proxy delivery (#607).

Consolidation:
- One pre-submission gate (CONTRIBUTING), one quick start (docker.md), one
  go.work paragraph (DEVELOPMENT), one AI disclosure block wording.
- README drops the duplicated quick start, tag table, doc index, and filler.
- PR template checklist reduced to the two items its sections don't cover.

* fix(catalog): move the person photo triple as a unit during enrichment

Address review findings on the credit-enrichment artwork guard.

photo_path, photo_source_path, and photo_thumbhash describe one image, but
each column was gated on its own value. A credit carries a photo URL and never
a source path, so replacing the "-" no-photo sentinel rewrote photo_path while
leaving the previous source URL in place. photo_source_path is what
UpdatePhotoIfSourceMatches keys the image-cache handshake on and what
EnqueueExistingProviderArtwork downloads from, so the finished job landed the
*old* image on the row, under the old image's thumbhash. All three columns now
move together under one decision taken on photo_path.

Deferring every replacement to the full person refresh also stranded people
with no tmdb/imdb/tvdb id: FindRefreshCandidates skips them, so nothing would
ever revisit a photo URL that had gone dead. The guard now protects cached
artwork specifically rather than any populated value — an empty column, the "-"
sentinel, and an uncached provider URL stay replaceable. "Not a cached key" is
the same LIKE '%://%' test the artwork GC trigger and the image cache sweep
use, so displacing a URL still queues nothing for deletion. Replacement
requires a genuinely different path, so re-scanning an unchanged credit remains
a no-op.

Tests: the SQL-shape test now matches whole generated clauses instead of loose
fragments, so a mis-wired column fails it, and the Postgres-backed test no
longer calls t.Fatalf on the parent T from inside a subtest. New cases cover
the stale-source binding, uncached-URL replacement, and the unchanged-credit
no-op. The behavioral coverage still needs SILO_TEST_DATABASE_URL, which CI
does not set.

Also build the batch enrichment SQL once instead of per batch.

* docs(contrib): require a readability prose pass and vendor the unslop skill

AI-written PR and issue bodies routinely arrive padded with filler and
promotional framing that costs review time. Vendor the unslop skill into
.claude/skills/ so contributors' agents pick it up in-repo, and add a
Prose pass section to docs/ai-contributions.md making the pass an
expectation. Worded explicitly as readability, not concealment: it may
not alter facts, pasted output, or logs, and disclosure still applies.

* fix(access): ungroup accounts promoted to admin

Create already leaves admins ungrouped because playback and catalog
policy is role-blind. Update did not: promoting a Default Group member
kept that group's stream cap and library list. Drop the group on
promote, reject assigning one to an existing admin, and ignore an
explicit group on admin create.

Co-authored-by: Quick <Quick104@users.noreply.github.com>

* fix(access): make admin accounts ungrouped everywhere

Review follow-up for the promote-clears-group fix. The rule now has one
write-side owner and one read-side guard instead of five copies:

- UserRepository.Update clears the group on promote and lands a demoted
  admin on the default group unless the write names one, so an ex-admin
  never becomes an uncapped non-admin.
- access.EffectivePolicyForUser ignores any group an admin row still
  carries (GroupApplies), covering every write path and pre-existing data.
- A data migration clears admins grouped before this rule and bumps their
  policy revision.
- PUT /admin/users/{id} rejects role=admin + access_group_id with 422
  whether the role is echoed or not, matching POST /admin/users; the
  handler no longer pre-clears the group itself.
- Invitations reject admin + access_group_id at send (422) instead of
  storing a group that accept silently drops.
- Web forms derive access_group_id=null for admins at submit; the detail
  form no longer wipes the picked group on a role toggle.

* fix(access): enforce admin ungrouping atomically and in list responses

Review follow-up:

- A group written without a role change is resolved against the row's
  current role inside the UPDATE, so a write racing a promotion cannot
  leave an admin grouped; the migration also adds a
  users_admin_ungrouped CHECK constraint as the durable backstop.
- GET /admin/users applies the same GroupApplies guard as the detail and
  auth endpoints, so a legacy grouped admin row never reports group
  ceilings anywhere.
- Regression test for toggling the role to admin and back keeping the
  picked group.
- Lint: spelling, wasted assignment.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(access): stage the admin-ungrouped constraint and clear pending admin invitations

Review follow-up:

- Drop the CHECK constraint from this release's migration: in a rolling
  upgrade, previous-version nodes still promote without clearing the
  group and the constraint would surface as a 500. The repository's
  in-statement CASE and the read-side guard already hold the invariant;
  add the constraint once every writer is on this version.
- The migration also clears the group on still-pending admin invitations
  created before this rule, so they advertise what accept will do.
- Both user forms preview the no-group policy while Admin is selected
  instead of the retained group's ceilings.

clientip.Middleware overwrites r.RemoteAddr with the header-derived viewer
address whenever the TCP peer is a trusted proxy, which includes Docker's
bridge. Mounting it on the ABS listener therefore defeated the login limiter's
deliberate RemoteAddr-only keying: an attacker behind any reverse proxy could
rotate X-Forwarded-For and buy a fresh burst bucket per request.

The middleware now preserves the pre-overwrite peer address in the request
context, and the limiter reads that instead. Anything else that must key on an
address a client cannot forge should do the same.

* fix(jellycompat): key stream telemetry on the upstream playback session

Compat attached observations under PlaybackSession.ID while the proxy,
nodesessions and playback_sessions_sync all key on playback.Session.ID, and
BuildGlobalView merges by exact SessionID string. One Jellyfin viewing therefore
showed as two merged sessions — a byte-less compat twin and the proxy record
carrying the traffic — and every compat session looked telemetry_only in parity.

Compat now attaches only under UpstreamSessionID. A play session does not learn
that id until ensureUpstreamPlayback/ensureTranscodeManifest has run, so the
pre-side-effect attach is a no-op on a session's first request and the handler
attaches again the moment the id exists, still before any byte is written. A
provisional key was rejected deliberately: it recreates exactly the ghost session
this fixes, and a session whose id did not exist a moment ago cannot have a
pending cut against it.

* fix(streamtelemetry): make Truncated recoverable and hold early realtime state

Three defects in the process-local registry, all found by review:

Truncated was sticky for the process lifetime. drop() set it and nothing ever
cleared it, so one transient capacity burst pinned the merged view's Complete
to false until a restart and made a later real truncation indistinguishable. It
now decays over Freshness — the same horizon BuildGlobalView uses to decide a
publisher is current — while the monotonic Dropped* counters keep the permanent
record.

SetRealtimeConnection was a no-op when the session did not exist yet. That is
the normal client ordering: the control socket opens as soon as a sessionId
exists, before the first media route is hit, so RealtimeConnectionAlive stayed
false for the whole of every live session. State for an unknown session is now
held per shard, applied when an attach creates the session, capacity-bounded
against the session budget, and pruned by the sweep.

The distributed cross-checks compared an env-supplied value against the DEFAULT
of the other knob, so setting one variable disabled distributed mode and blamed
a variable the operator never set. Knobs left at their defaults now move to
satisfy the invariant; only a pair pinned to genuinely inconsistent values is an
error, and only the variables actually set are named.

* fix(httpstream): give every ReadFrom slice a full stall window

The bumpStep throttle was written for the 32 KB Write path, where one
SetWriteDeadline per chunk would be wasteful. Applying it to ReadFrom slices
buys nothing — a slice is already bounded at 4 MiB — and costs correctness: a
slice completing less than a step after the last bump got no refresh, so the
next one started with as little as window-step remaining. The real guaranteed
floor was ~203 kbit/s, not the 186 kbit/s the constant and both design documents
promise, and a client sustaining the documented rate was reaped as stalled.

Slices now bump unconditionally, before the first as well as between each, which
is what the pre-CopyChunked loop did. Costs at most one syscall per 4 MiB.

The existing deadline tests construct the writer with step=0 and so never
exercised the throttle; the two added here fail on the unfixed code.

* fix(proxy): credit the egress meter often enough to measure slow viewers

meteredResponseWriter previously hid io.ReaderFrom on purpose, so every byte
reached egressMeter.Add through a ~32 KB Write. Forwarding ReadFrom restored
sendfile but moved crediting to once per completed 4 MiB slice, which a
200-500 kbit/s direct-play viewer takes 60-170 s to fill. RateKbps averages over
60 s, so those streams read as zero for most samples: /api/v1/status
under-reports committed egress and nodepool's effectiveEgressKbps can admit
sessions onto a saturated proxy.

Metered slices are now 256 KiB — a credit every 4-10 s at those rates, well
inside the window, and still 8x more per sendfile call than the Write path it
replaced. Slice size here is a rate-fidelity constraint, not a tuning knob.

* fix(downloads): roll the direct-download deadline and carry the profile

handleDirectDownload passed the raw ResponseWriter to ServeDirect, so unlike the
sibling /downloads/{id}/file it had no rolling deadline and the API server's
absolute 120 s WriteTimeout truncated any original large enough to take longer.
Excluding the route from compression made it one unbounded sendfile, so the
whole body now rides on that single deadline.

redirectDirectDownload hardcoded an empty profile id in both the proxy redirect
and the telemetry attach, while the local branch two lines away reads the real
one. Proxy-served traffic was therefore missing from per-profile attribution in
telemetry, in the stream token claim and in the node session.

* fix(streamtelemetry): fold ranged transfers, guard delta publishes, split conflicts

Transfers were one record per HTTP request keyed by observation id, so ranged
byte routes — audiobook file reads, download resumes, ebook fetches — could
exhaust MaxTransfers within one retention window while RequestCount, the field
that exists to count exactly this, stayed pinned at 1. A transfer is now one
subject pouring one file over one route, and overlapping requests fold into it.

A delta publish rewrites only changed fields and assumed the Redis hash still
held the rest. An eviction, an out-of-band DEL, a replica failover or a lapsed
PExpire drops it with no error, leaving under-reported sessions for up to
FullResyncEvery publishes. An HLEN inside the same transaction now catches the
mismatch and forces the next publish full, self-healing in one sweep.

recordConflicts appended started_at_replaced without setting
hasIdentityConflict, so the exported flag could disagree with the exported list.
A pure authority upgrade that confirms the recorded instant now records nothing
at all — it is not a conflict and should never have consumed the budget — and a
replacement that moves the value sets both.

Also documents two limitations rather than half-fixing them: clock skew is only
detectable for a publisher running ahead, since the roster score is the
publisher's own clock; and observedWriter.ReadFrom samples the cut flag once,
which the enforcement change that first calls cut.Store has to make uniform
across h1 and h2.

* refactor(httpstream): one ForwardReadFrom helper for all nine wrappers

Nine ResponseWriter wrappers across five packages hand-rolled the same tail:
assert the inner writer's io.ReaderFrom, CopyChunked through it, fall back to
io.Copy over WriterOnly. Because io.Copy finds ReaderFrom by direct assertion
and never through Unwrap, this forwarding is mandatory on every media-route
wrapper — so a fix to it had to be re-applied nine times and a missed site
silently dropped to the fallback, losing zero-copy sendfile along with that
wrapper's byte accounting.

Behavior is unchanged; each call site keeps its own chunk size and record
callback.

* refactor(streamtelemetry): share viewer-IP, env and client-info helpers

Four families built the same clientip-then-RemoteAddr fallback chain inline
while streamtelemetry already had it unexported; a fix to it (IPv6 handling,
say) would have had to land in four places or the families would report
different viewer addresses into the same merged view. Exported as ViewerIP and
adopted everywhere.

envEnabled was the ninth independent "is this env var truthy" parser in the
tree, each accepting slightly different spellings. Adds internal/envutil and
adopts it in both telemetry packages; the remaining copies should migrate as
the code around them is touched.

checkVersion re-parsed every record into a throwaway header struct before
unmarshalling it again into a wire type that already carries the version, so a
merged-view rebuild — measured at ~347 ms for 50 000 sessions, nearly all
decode — did the JSON work twice.

ConfigFromEnv ran twice at startup because the view cache re-read the
environment just to get ViewTTL, logging any invalid variable twice; it now
takes the TTL off the registry that already parsed it.

playbackClientInfoFromRequest wrapped PlaybackClientInfoFromRequest wrapped
playback.ClientInfoFromRequest — three names, one body. Callers now use the
playback package directly.

* docs: document the admin stream-telemetry parity endpoint

CLAUDE.md requires a docs/*-api.md entry and a changelog entry for a
client-visible API change. No admin-API document existed — the ~20 sibling
routes in the same router block are undocumented too — so this adds one, scoped
honestly to what it covers, with the full response shape for
GET /api/v1/admin/stream-telemetry/parity and the caveats an operator needs to
read a report correctly.

* docs: distill the streaming write-deadline design into architecture

PR #675 pruned docs/superpowers and the shipped design artifacts, distilling the
durable content into docs/architecture first. The streaming write-deadline
document was deleted on main under that rollup while this branch was extending
its writer-chain conformance section, which is the whole of the conflict between
the two.

This carries the durable half forward on main's own pattern: the invariants a
future change has to respect — the rolling-deadline contract, why slice size is a
correctness constraint rather than a knob, the two rules every ResponseWriter
wrapper on a media route must follow, the one-limiter sendfile trap, why chi's
compressor is bypassed rather than repaired, and how conformance is actually
verified. The one-shot half — the 2026-07-09 debugging session, the per-file
application table, the rollout plan, the silo-apple follow-up list — goes with
the deletion.

Also records the two rules this branch's review turned up: the bump throttle
belongs to Write and never to a ReadFrom slice, and the proxy egress meter has
the same shape of constraint at a different value.

* chore: ignore skill secrets and state paths

* feat(playback): tokenless V3 playback, DV7 client transforms, admin transcode honesty

Playback protocol V3:
- Tokenless playback: header-authenticated media with signed stream URL
  reconstruction, sticky per-attempt feature set, and tokenless subtitle
  delivery (playback_v3, resolver, transcode manager, protocol_v3).
- Downloads and auth updates supporting the same flow; access-group clause
  coverage for repository queries.

Admin activity honesty:
- Plumb target_audio_channels end to end (new migration, session sync,
  reconciler, admin session payload, web types) so a transcode target
  renders its real output layout ("AAC 5.1"), falling back to the bare
  codec when unknown - never the source channel count.
- Rename the "Audio SW" chip to "Audio Transcode"; it labels a plan
  decision (video copied, audio transcoded), not a client capability.

Client counterpart: silo-apple branch t3code/replace-custom-engine-aether
(AetherEngine player). This server branch is required for that client -
AetherEngine playback negotiation (tokenless media, DV Profile 7
client-transform grants) does not work against older servers.

* feat(playback): restore proxy and transcode-node egress for header-authenticated media

header_authenticated_media_v1 kept every media byte on the API server
because proxies could only authenticate from the signed URL token that
mode removes. A new attempt-sticky opt-in, authorized_media_origins_v1,
restores distributed egress without putting a credential back in any URL:

- Plans for an attempt that negotiated both features may return absolute,
  credential-free proxy URLs (/stream/v3/{session_id} family) for direct
  play, progressive remux, and node-executed HLS.
- The proxy is told what to serve out of band: the API writes the session
  recipe to a Redis proxy-grant store (silo:proxygrant:, sibling of the
  noderecipe handoff), overwritten on replan and revoked on session stop,
  abort, and uncommitted-transport rollback.
- The proxy authenticates the caller itself: bearer JWT against the live
  signing secret plus the same auth_sessions liveness check the API runs,
  then ownership against the grant. Revoking a login stops proxy playback
  immediately. Node-relay tokens are minted proxy-side and never reach
  the client.
- RecipeCard now carries DVProfile/AudioOnly so a grant-served remux
  reproduces the exact bytes the token path would have.
- The progressive-remux escalation to HLS now applies only when no proxy
  origin is available; grant-write failure falls back to the API origin
  under the same local_transcode_fallback gate as the no-origins mode.

Header-auth-only clients and deployments without a proxy pool keep the
current API-local behavior unchanged.

* fix(playback): address automated review findings on tokenless proxy egress

- Preserve the displaced proxy grant across a replan and restore it on
  rollback, so a failed replacement no longer 404s the restored plan's
  proxy URL; revoke the grant when a proxy-egress attempt commits onto a
  transport the API serves itself (identity, relay, or local transcode).
- Gate the progressive-remux escalation on a usable grant store as well as
  configured proxies: a process that can never authorize proxy egress
  escalates to HLS instead of refusing forever, while transient proxy
  ineligibility keeps the legacy retryable refusal.
- Advertise target_audio_channels in the admin sessions capability
  endpoint so independently deployed clients can feature-detect it.
- Reject an unrecognized video_evidence value on flat download payloads
  instead of silently resolving from flat claims.
- Handle SessionUnauthorized defensively in the stream and jellycompat
  serve switches (unreachable today; prevents a nil dereference if the
  caller invariants ever drift).
- Document the tokenless replica-affinity constraint in the protocol spec.

* fix(playback): survive transcode-node restarts on tokenless attempts and stop charging unused proxies

- A header-authenticated remote transcode published no stream token, so
  after a transcode-node restart neither the client nor the API relay had
  a recipe to forward and playback 404ed until a replan. The API now
  writes the transport's recipe card to the shared noderecipe store
  (keyed by transport id, like the jellycompat handoff), and the node's
  reconstruct path falls back to the store when no X-Silo-Stream-Token is
  present — the token was a recipe source, never the route's
  authorization. Recipes are deleted on every deliberate teardown
  (transport replacement, rollback, session stop/abort); the TTL only
  backstops a crashed API process.
- When a start reserved a proxy+transcode pair but published a URL the
  proxy does not serve (unwritable egress grant, or the legacy no-token
  fallback), the planner kept charging the proxy's job slot and estimated
  bandwidth until the reservation aged out. New ReleaseSessionProxy drops
  only the proxy half; the transcode node keeps its charge because it is
  running the job.
- The proxy-grant store interface is renamed recipeCardStoreV3 and shared
  by both handler fields, since it now carries two key spaces.

* fix(streamtelemetry): enrol tokenless /stream/v3 proxy routes

The merge left the five credential-free grant routes registered but
unclassified, so bytes served through authorized_media_origins_v1 were
invisible to stream telemetry. Enrol them:

- Declare GET+HEAD /stream/v3/{session_id} (playback), GET+HEAD
  .../master.m3u8 (manifest) and GET .../segment/{name} (playback), all
  viewer egress and capability-relevant, and wrap each registration in
  observeProxy.
- Give them CanonicalSessionKey "verified_media_grant" rather than the
  "verified_stream_token" the proxyRoute helper hardcodes. The field is
  descriptive — it is only compared in sameDeclaration and emitted into the
  route manifest, and no code branches on its value — but these routes prove
  entitlement with a Redis grant plus the caller's own bearer token, never a
  stream token, so labelling them otherwise would be false.
- Attach the viewer in relayGrantToTranscodeNode, the single path both grant
  transcode handlers take. The proxy->node hop itself stays internal_relay.

* feat(streamtelemetry): enable by default and derive distributed mode from redis

Stream telemetry measured nothing on a fresh install: both switches were
opt-in, so the parity comparison every P1 threshold depends on only ever ran
where someone had already read the design doc. Observation is process-local,
off the hot path and bounded, so the safer default is on.

SILO_STREAM_TELEMETRY_ENABLED now defaults to true and is a per-process kill
switch; SILO_STREAM_TELEMETRY_FAMILIES still narrows observation or drops one
misbehaving family without losing the rest. SILO_STREAM_TELEMETRY_DISTRIBUTED
is no longer a flag the operator has to keep in sync with their topology:
unset, the mode follows whether Redis is configured, so a single-container
install stays on LocalStore and a cluster merges. Setting it pins the mode
either way, and a rejected distributed configuration pins it off so the
derivation cannot re-enable exactly what was just refused.

Both switches read a set-but-unparseable value as false rather than as the
default (envutil.BoolDefault). For a default-on flag that means a typo in the
kill switch turns telemetry OFF, which is the fail-safe direction: the
operator was reaching for "stop observing", and a mistyped disable that
quietly left the feature running is the failure that costs them.

instead of a curated subset. The variable stays as a narrowing/kill knob —
naming it takes families away rather than staging them in.

Adds streamtelemetry.AllFamilies as the single canonical family list so
ObservesFamily and ObservedFamilies don't hand-duplicate it, updates the
design doc's family-gate section and env table to match present-tense
behavior (keeping the original staged-rollout narrative as history), and
updates the feature changelog to say every family is observed out of the box.

* feat(scanner): persist H.264 copy-safety verdicts and move analysis off browse paths

The multi-PPS copy-safety scan ran on media-page load and was forgotten on
every restart, re-reading the opening seconds of every browsed H.264 file —
painfully slow on remote storage. The verdict is now persisted on media_files
(self-validating against file size+mtime, so in-place rewrites invalidate it
without writer coordination), the scan window drops from 15s to 5s, browse
pages never trigger the scan (EnsureProbeOnly), and concurrent first scans
share one ffmpeg via singleflight. The lazy path stays fail-closed and
stateless on errors.

* feat(playback): optimistic remux race with server-initiated plan invalidation

When an H.264 file's copy-safety verdict is unknown, playback no longer
blocks on the bitstream scan: the planner issues the remux optimistically,
the scan runs behind the plan, and an unsafe verdict withdraws it. Sessions
that negotiated the new plan_invalidated_v1 feature get a pushed
plan_invalidated realtime command and switch via their normal
failure_recovery replan; everything else — including today's mobile apps —
is stopped and recovers onto a transcode through the persisted verdict.
Watch pages and playback start now never wait on the scan. jellycompat
sessions are exempt: their route selection does not consult the verdict yet.

Web client implements the feature; Apple/Android follow-ups tracked in their
repos.

* fix(playback): sweep sessions that register after a copy-unsafe verdict lands

The async scan can beat the start path by milliseconds: a plan is decided,
the verdict persists before the session is registered, and the notifier's
immediate pass finds nothing — leaving the session on a condemned remux
route with no second look (observed live on dev: plan at t, verdict at
t+4ms, playback restarting on corrupt output). VideoCopyUnsafe now schedules
one file-wide sweep after the settle window that considers only sessions the
immediate pass never saw.

* fix(playback): harden copy-safety invalidation against review findings

Four fixes from PR review: the web client defers a plan_invalidated that
races an in-flight replan adoption instead of no-opping it; a race scan that
finds another replica already persisted an unsafe verdict still notifies its
own sessions; stopping a session now interrupts an in-flight progressive
remux response (previously only the client could end it — ffmpeg was bound
solely to the request context); and background scans are capped at four
concurrent ffmpeg processes globally.

Review fixes: a realtime result naming another session's command is now

Review round two: sessions the notifier could not classify mid-replan-commit

before registration; reconstructing a video stream-copy transport (progressive
or HLS) now consults the persisted verdict, closing the replica-failover hole
where a condemned remux could be re-served with nothing left to withdraw it;
and a verdict whose database write failed is memoized as unpersisted and the
write retried on later requests without rerunning ffmpeg.

Round three review fixes: the reconstruction verdict gate moves ahead of

leaked session; a failed local scan re-reads the row and applies a verdict
another replica persisted concurrently; and the scan singleflight is keyed by
file generation (id+size+mtime) so a replaced file cannot consume the old
generation's verdict.

* fix(playback): re-engage the copy-safety race on revival and close generation races

Round four review fixes, closed as one gap: a video stream-copy transport
revived or replanned while the verdict was unknown or unpersisted never
re-engaged the race machinery. KnownCopySafetyVerdict answers from memo then
row (retrying an unpersisted write, never running ffmpeg); both revival paths
consult it and kick the racer when nothing condemns the card; and a race
request arriving mid-scan queues one follow-up pass instead of being dropped.
Verdict writes are now conditional on the scanned file generation so a slow
old-generation scan can neither overwrite the replacement's verdict nor
notify its sessions. The web client scopes its adoption-settle wait to the
load sequence that owns the session, so a hung superseded start cannot stall
an invalidation past the command deadline. Test hygiene: atomic node-hit
counter, observable wait instead of a sleep.

* feat(playback): let original players manage HDR

Accept delivery-scoped client claims for Aether-managed dynamic range and selected audio on original HTTP while retaining packaged-output gates and the existing behavior for clients that do not claim support.

* fix(catalog): reject disabled dual-library items

* chore(catalog): satisfy changed-lines lint

* fix(sections): enforce disabled episode hydration scope

* fix(scanner): scope file reconciliation to changed path

* fix(scanner): unify present-state repair and drop dead extras sync call

Review follow-ups for the file-scoped reconciliation:

- Collapse syncPresentLibraryState and syncPresentFileState into one
  syncPresentState implementation with an optional exact-path scope, so the
  two variants cannot drift. The folder-wide entry point emits the same SQL
  as before; the episode-membership statement is unified on the sibling-join
  shape so first_seen_at always aggregates over all of an episode's active
  files.
- Run the four repair statements in a single transaction instead of four
  autocommit round-trips, so a crash mid-repair cannot leave a row with its
  links cleared but its memberships unrestored.
- Remove the syncPresentFileState call in the extras-conversion branch: the
  preceding Upsert already nulls the row's content/episode links, making
  every statement a no-op there. The membership cleanup at that site comes
  from the unchanged reconcileLibraryMemberships call.
- Drop the redundant COALESCE inside GREATEST in the series denorm bump.
- Extend the regression test to drive both scopes through the unified body,
  including dangling content link repair.
