📝 WalkthroughWalkthroughThis change replaces S3-only artwork paths with a canonical, backend-neutral artwork store. It adds portable content-addressed revisions with strict manifests, target-bound signed delivery, resilient fallback, inventory and health tracking, seed adoption, safe purge, garbage collection, admin recovery tools, and updates catalog, API, jellycompat, notification, and branding integrations accordingly.

Stop advertising an unenforced original-image width cap
For a valid capability whose stored revision is unavailable, requesting the original variant returns the validated source bytes unchanged, so a provider image may be far wider than 1920 pixels; square avatar materialization likewise does not apply MaxCachedOriginalDimension to its original. This capability nevertheless tells clients that every original is bounded by that value, which can make them budget decode memory and bandwidth incorrectly and then receive images up to the much larger source-pixel limit. Apply the cap to every original delivery path or report a contract that distinguishes uncapped originals.

When a copied portable tree contains a corrupted or truncated variant whose key still exists, this only stats the manifest's object keys and marks the revision complete; it never calls ValidateManifestObjects or compares the recorded sizes and digests. ImportPortable then registers inventory_complete=TRUE and may adopt the revision as live, so the import reports a corrupt copy as verified until a client happens to request that variant. Hash every imported object against the manifest before registration.

Verified and refuted — verifyPortableRevision calls artworkkey.ReadManifest, which has invoked ValidateManifestObjects internally since its introduction: it reads every listed variant, checks the exact recorded byte size, verifies each SHA-256 digest, and re-derives the revision digest from the bytes; a truncated or corrupted variant fails verification and the revision is skipped rather than registered inventory_complete. The statArtworkKeys call flagged here runs after that validation and only collects object sizes/content types for the inventory row. No change made.

When a plugin:// job is processed, ImageCacheProcessor passes the resolved HTTP download URL as SourceURL and preserves the original plugin reference in SourceReference, but this classifier reads only SourceURL. Consequently plugin materializations are recorded and metered as provider, making source_classes accounting and silo_artwork_materializations_total inaccurate for normal plugin jobs. Classify from SourceReference when it is present, falling back to SourceURL for direct HTTP sources.
Useful? React with 👍 / 👎.
There was a problem hiding this comment.
Verified and refuted — the code reading is right (artworkSourceClass sees the resolved URL), but the claimed misaccounting doesn't occur: real plugin references carry the plugin's slug as their scheme (e.g. tvdb://...), and the canonical reference classifier (artworkSourceClassFromReference) labels every non-reserved scheme "provider" too — "plugin" is reserved for a literal plugin:// prefix that no production flow emits. Classifying from SourceReference would therefore produce the identical label, and the current result already agrees with the inventory's recorded source_class; the plugin label is dead vocabulary in both classifiers, not an inaccuracy at this call site. No change made.

…ed test execution Second review round (Codex bot) plus first real execution of the DB-gated tests against a migrated Postgres (isolated dev-builder sandbox): - generation-dependent consumers (artwork storage service, image cacher and upload revision trackers, seed import accounting) read the store generation through live accessors instead of startup snapshots, so runtime generation rotation no longer records inventory against a stale binding - person refresh follows artwork.remote_materialization hot-reloads: deps are wired unconditionally and enqueueing is gated by an atomic live policy flag - shared/NAS local stores re-resolve the confined os.Root before mount sentinel validation, so a filesystem swapped in at the same pathname can no longer pass validation through the stale descriptor - untracked (SQLite user-store) materializations mark any existing GC candidate as a permanently retained unarmed seed once the revision path is known; the marker survives catalog displacement, inventory refresh, seed import, dormant sweeps, and GC claiming, so shared objects referenced only from SQLite can no longer be deleted - successful repair clears loss state only for the revision it actually published; a changed previous revision stays missing for rows still selecting it - the ladder-fence trigger's plpgsql variable shadowed manifest.image_type, making the reopen trigger error (42702) whenever a late old-ladder publication fired after completion; renamed to slot_image_type (migration is part of this PR, edited in place) - DB-gated test fixes: gc-candidate seeds supply the non-defaulted not_before; the season-localization assertion follows natural-key job addressing; the reconcile storage-error test now proves resume-safety by resuming from the saved checkpoint instead of asserting its zero value; the checkpoint-resume test pre-cleans conflicting job rows Validation: full local Go suite green; adminjob and metadata packages executed green against a real migrated Postgres on an isolated sandbox (first-ever execution of these DB-gated tests), including the checkpoint resume CTE and the fixed trigger.

…, branding size guard - episode responses that substitute the parent series backdrop/poster for a missing still now mint the capability for the surface that owns the bytes (series item-backdrops/posters keyed by series ID) instead of signing them as episode stills, which dead-ended at the episode's empty still_path under resilient delivery; the fallback variant derives from the owning slot's ladder - the artwork capability endpoint reads direct-delivery availability live through the resolver's own accessor, so a hot-reloaded delivery policy can no longer contradict actual URL minting - branding assets reject stored objects above the kind's upload limit (metadata check plus limit+1 read guard) instead of silently serving truncated bytes; the error wraps ErrAssetNotConfigured so the public endpoint falls back to default branding - deflake the direct-library tamper test: the substituted last character now always differs from the original, closing the 1-in-64 quantized-expiry windows where the "tampered" URL equaled the valid one Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ivery is the only behavior
Removes artwork.delivery_policy and artwork.url_auth and the entire direct
delivery mode: the raw-key route and handler, SignDirectKey/VerifyDirectKey,
DirectURLProvider/Handle.DirectURL/S3Store.ReadURL, the resolver's policy and
url-auth plumbing and its mint-time variant selection, and the direct-only
branches in the metadata image resolver. Every artwork URL is now a signed
target capability served through /api/v1/artwork; the direct-library route is
unchanged.
The capability endpoint keeps delivery_policy, delivery_modes, and
automatic_recovery pinned constant ("resilient", ["api"], true) following the
v1-scope precedent for retained feature-detection fields. Settings UI, setup
wizard, and docs updated; removals recorded in the pre-lock removals table.
Stale server_settings rows for the removed keys are ignored by config loading;
no cleanup migration since only dev installs ever wrote them.
Maintainer-directed simplification: one delivery behavior, no knob.

…xplicit store rebuild Removes artwork.local_ownership: every local store now gets the cautious semantics that were previously opt-in for shared/NAS roots. Bootstrap stays fully automatic (create, marker, adopt, pin at first materialization); once a generation is pinned, a missing root goes unavailable and absent or mismatched markers go wrong_mount — the root is re-resolved on every health check, and the store is never recreated or generation-rotated automatically. A pinned store that loses its root raises a persistent store_root_missing alert. Recovery from a deliberately emptied root becomes an explicit admin action: POST /api/v1/admin/artwork/rebuild (Handle.RebuildEmpty) recreates an absent root, refuses a root that still contains objects (store_not_empty), mints a fresh generation, rotates the durable pin atomically with the live one, and enters empty_rebuilding for the existing recovery loop to converge. S3 returns unsupported_backend: rotating identity over a populated bucket is unsafe, and the authoritative-empty path already covers the genuinely empty case. The storage card gains a confirm-gated Rebuild button when a local store is unavailable or wrong-mount. Removes artwork.seed_adoption_grace: the copied-store adoption grace is a fixed 30 days; unadopted seeds are reclaimed by the scheduled artwork-revision GC, with the dry-runnable purge job as the on-demand cleanup. Settings UI, wizard, docs, and the pre-lock removals table updated; the restart-required registry entry for local_ownership removed with the setting. Maintainer-directed simplification.

refuses (episodes are not media_items rows), so the cards 404ed.
Section fetchers now record the owning entity per image: the episode catalog
substitution happens in Go via chooseEpisodeArtwork and returns
SectionArtworkOwner metadata (series/season/episode) for poster, backdrop,
and logo; the custom-filter path threads meta it previously dropped, the
recipe bridge preserves it, and the handler builds each capability from its
actual owner (season posters, item posters/backdrops/logos keyed by series,
or episode stills), falling back to a batch hydrator for episode items that
arrive without complete meta. Non-episode items are unchanged.
Found live on the artwork-storage deployment: capability decoded to
{item posters, episode-tvdb-…} and 404ed.

…ity, people variant, LIKE escaping Fourth review-bot round: - managed-download artwork serves root-relative capabilities through the in-process artwork handler instead of handing them to the HTTP client, which failed with an unsupported protocol scheme for stored artwork - repair enqueues re-admit permanently-parked failed image jobs with the normal failed-job cooldown as the throttle, so a later-recovered source can rematerialize; non-repair enqueues keep parking semantics - image caching carries the original plugin/provider reference alongside the resolved download URL, so adoption fingerprints and the portable source-adoption index work for normal provider jobs again - people responses default stored photos to the medium (w500-class) variant instead of original when no image size is requested - legacy-prefix GC escapes LIKE metacharacters with an explicit ESCAPE clause, so prefixes containing %/_ cannot be deferred forever by unrelated matches Full Go suite green locally; metadata and adminjob DB-gated tests executed green against a migrated Postgres on an isolated sandbox.

…ed targets, and round-5 findings Fifth review-bot round: - readiness no longer double-checks the canonical S3 artwork bucket with fatal severity: when the artwork store is the public bucket, the fatal S3 dependency falls back to the private bucket (or none) and the degradable artwork check owns the outage — an S3 outage now returns 200 degraded instead of evicting every node while resilient delivery still serves - wrong-mount and unavailable stores gate reads, stats, matches, and listing in the health wrapper, so reconciliation and maintenance can no longer misread a replaced mount's empty directory as authoritative absence and reset catalog or branding references; empty_rebuilding reads still flow - localized poster/backdrop overrides are signed as localized surfaces keyed by content ID and language, so list responses serve the localized image instead of reloading the base row - a capacity-probe failure no longer downgrades unavailable/wrong_mount to degraded, which was hiding the rebuild button in the primary missing-root scenario - the scanner image-caching switch and setup wizard read/write the canonical artwork.remote_materialization key instead of only the legacy fallback - filesystem-root validation rejects any path equal to its own parent (covers /, C:\, and UNC roots), in config validation and the store - appliedArtworkTarget guards nil season/episode pointers instead of panicking after publish - untracked materializations retain the GC candidate only after the last failure point, so a failed upload cannot leave an orphan permanently retained - the non-library resolver error wraps ErrInvalidKey so batch resolution keeps logging expected references at debug level Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

… and jobs Fixes the 27 review-bot findings (18 distinct defects) still valid at 5803fd5, verified against current code before changing anything: Delivery and handlers - Serve Range/If-Range from non-seekable (S3) bodies by buffering bounded objects through http.ServeContent; streaming path unchanged without Range. - Verified-digest cache entries expire hourly so a same-size/same-mtime byte replacement cannot be trusted indefinitely; same TTL treatment for the direct-library sidecar fingerprint cache. - Emergency cache is consulted before the recovery limiter for direct http(s) sources, so cached bytes no longer exhaust the token budget. - Missing chapter thumbnails re-extract (clear the chapter's thumbnail in media_files.chapters, repair-queued) instead of becoming protected losses. - Calendar season premieres sign SurfaceSeasonPosters only when the season poster was selected; resolved posters are keyed per event by Target.CacheKey. - Item detail localizes poster/backdrop/logo per slot, mirroring the list path. Store - Filesystem root is borrow-counted: ReopenRoot retires without closing under in-flight operations, and an unchanged mount (os.SameFile) skips the swap. - ListPage prunes subtrees that cannot intersect cursor or prefix (O(depth+limit) per page instead of quadratic re-walks). - S3 listings anchor an empty logical prefix at keyPrefix+"/" so sibling key spaces (assets vs assets-old) cannot leak into emptiness proofs. - PinMismatchError and the architecture doc now describe the real supported migration flow (byte-for-byte copy including sentinels; admin rebuild for an empty local root) instead of pointing at a task that cannot rebind. Jobs, recovery, and accounting - Purge revalidation fetch-verifies remote sources (SSRF-safe fetcher, resolver wired in main) and re-runs on resume; unverifiable sources stay protected. - RebuildEmpty persists empty_rebuilding intent before rotating marker+pin; recovery re-enters on a persisted intent with a mismatched generation. - Refresh recomputes MissingObjects from the registry at finalization instead of carrying resumed counters into the published snapshot. - Purge completion and the follow-up accounting refresh enqueue are atomic. - A disabled (passthrough) processor claims repair jobs only, so empty-store recovery converges without enabling materialization. - user_personal_collections sweep pages by (user_id, id) matching its PK. - Ladder backfill emits series natural keys and dedups on season/episode, completing the 88a2999 conversion. - New migration re-creates the corrected reopen_image_ladder_backfill_v2 for databases that applied 20260826010050 before the in-place fix. - Inventory snapshot age is computed at scrape time; wrong-mount detections count on entry, not exit. - Passthrough copy now says what the code does: not copied into the store, still delivered through Silo artwork URLs with request-time source fetch.

The rebase onto main landed on the admin-settings redesign (#795), which replaced the Scanner and Storage tabs this branch had extended. Move the artwork controls into the new layout instead of resurrecting the deleted pages: - Library & Metadata: the artwork toggle becomes the backend-neutral "Cache remote artwork" control, deriving canonical-first from artwork.remote_materialization with metadata.cache_images fallback and writing both keys, with the S3-bucket lock removed (a local store needs no bucket). - Storage & Database: new Artwork storage group with the backend selector (auto/local/s3) and local path, both restart-required. - Settings search index updated for the moved controls; legacy ScannerSettings/StorageSettings pages and the superseded S3-lock tests removed; toggle coverage ported onto the Library & Metadata tests.

Clamp wide backdrop rungs to w780 when the minted slot is a still, the same clamp the legacy path pipeline applied in BackdropVariantPath. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

When a shared/NAS filesystem rejects hard links, concurrent writers can both pass the initial absence check and reach this fallback; on POSIX, Rename replaces an existing destination, so the later writer silently overwrites the first and both calls report success instead of returning ErrContentMismatch. This violates WriteImmutable precisely on the multi-node filesystems this backend supports; publish with a no-replace operation or otherwise serialize competing writers on this fallback.

…rebuild ArtworkStorageService.RebuildEmpty persisted the durable empty_rebuilding intent before the handle could reject the request, so a rebuild refused for an S3 backend (422) or a non-empty local root (409) stranded recovery state that shouldReenterArtworkRecovery — which deliberately ignores generation mismatches — later adopted, forcing a healthy populated store into bulk recovery. Handle.RebuildEmpty now takes a recordIntent callback invoked after the rebuild is validated (local backend, empty root) and before the durable marker/pin rotation, preserving the intent-before-rotation crash design: a rejected rebuild leaves no durable side effects, while a crash after the intent lands remains the harmless resume-a-rebuild state. Tests pin that recordIntent runs pre-rotation on acceptance and never on rejection. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Batch target resolution appended and signed targets unconditionally, so an item with no logo or backdrop got a working capability URL whose delivery could only ever serve the bundled placeholder — clients that branch on an empty URL field (logo vs. title text) rendered gray placeholders instead. Refuse to mint when the target carries no selected reference, restoring the pre-capability contract that absent artwork is an empty URL field; lost-but-selected artwork keeps its capability and the placeholder path. docs/artwork-api.md now states the distinction.

When a batched caller supplies the persisted "-" sentinel, this check still mints a capability even though the rest of the catalog layer treats both "" and "-" as no selection (for example, the singular path rejects it in PresignArtworkTargetImageURLWithExpiry). Batch paths such as manga chapters can therefore publish a signed URL that only resolves to a placeholder instead of leaving the URL field empty as the API contract requires. Reject "-" here along with the empty reference.

…erified roots Two probe-path races against the store's mount guarantees: - ProbeNow called check() without checkMu, so a probe stalled on a dead mount could interleave with RebuildEmpty, write the pre-rebuild generation back over the freshly rotated pin, and misreport the rebuild as wrong_mount. It now serializes on the same mutex as Check and RebuildEmpty. - openRootExisting cached a newly opened root without the pin and marker verification openRoot performs, letting concurrent writes borrow a swapped mount during the very probe about to flag it. It now returns a transient uncached handle; the verified cache is populated only by openRoot. A missing pinned root is also classified as ErrBackendUnavailable so probes force unavailable rather than a generic failure. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ting, unpark rebuild repairs Three delivery/recovery defects: - isRequestRecoverableArtworkSource's scheme catch-all admitted legacy s3:// and local:// sources the repair queue rejects, so their losses were marked repair-queued while no job was ever admitted — no protected-loss alert, MissingReferences stuck above zero, store degraded forever. Recoverability now matches queue admissibility via isNonProviderImageScheme; such rows take the protected branch and raise the alert. Unit test pins the split. - ArtworkPublished ran the recovered metric and the rebuild-status aggregate (an unindexed job-table scan plus the loss-reference union) for every publication, turning a library scan into a per-image accounting pass and counting all publications as recoveries. The loss-state UPDATE now reports whether it actually cleared anything; metric and status run only for real recoveries or repair jobs. A new partial index (CONCURRENTLY, per repo precedent) serves the outstanding-repair count. - EnqueueRepairBatch parked re-admitted failed targets behind the 7-day request-burst cooldown, and rebuild completion counts queued repair jobs regardless of due time — so one previously-failed source held empty_rebuilding for a week. Bulk-recovery re-admissions are now due immediately: one prompt attempt recovers the target or returns it to 'failed', which does not gate completion. Request-time EnqueueRepair keeps the cooldown.

…, and collection backdrops Three places discarded the variant the request (or the surface) called for: - itemArtworkTargetURL passed its resolved ladder variant into the image_size parameter of PresignArtworkTargetImageURL, where it fails to parse and falls back to the medium rung — image_size was a no-op on single-item list and season responses, and default cards shipped w500 instead of w300. It now presigns by variant directly. - Section backdrops used a flat w1280 default and collapsed passthrough references into a w300 card request, so featured heroes lost the legacy pipeline's w1920 and provider/plugin-referenced heroes rendered from a 300px image. The per-section split from sectionBackdropPath is restored (w1280 for Continue Watching / Next Up, w1920 featured otherwise) and the card-collapse heuristic is removed; the episode still-ladder clamp still applies. - Collection backdrops (native, compat BoxSet, and compat image routes) were pinned to w300; full-screen backdrops now use the w1280 rung the collection-backdrop ladder exists for. Posters keep card size. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…xt boot An explicit artwork.storage_backend that contradicts the machine-managed store pin made artworkstore.Open return its always-fatal PinMismatchError at the next start — the server never came back up and the settings UI needed to revert the value was unreachable. Auto had the same trap from the other side: configuring a public bucket for subtitles or branding flipped a pinned-local install to S3 at boot. - resolveBackend now honors the pin under auto: a pinned install keeps its backend regardless of later bucket configuration, and a pinned-S3 install without a bucket gets an actionable error instead of a mismatch. - Both settings write paths (batch and legacy single-key) refuse an explicit backend that conflicts with the pin, with migration guidance in the error; auto and the pinned backend still save.

When remote materialization is passthrough, or a stored revision is missing, requesting image_size=original returns the provider bytes unchanged here. ValidateImage permits images up to 80 megapixels, while /api/v1/capabilities/images promises that originals never exceed original_max_width_px (1920), so clients can unexpectedly download and decode extremely large images. Run the fallback original through the same capped re-encoding used by GenerateVariants before serving it.

Although finalization now recomputes missing-object counts, a timed-out or cancelled refresh still restores OrphanObjects, adoption-index, branding, and legacy-upload totals together with StoreCursor. If an already-scanned object is added, removed, or repaired before the job resumes, these accumulated counters are retained while listing continues strictly after the cursor, and the stale values are published as a fresh snapshot. Restart the store scan or recompute these totals authoritatively when resuming.

Problem
Silo required S3-compatible object storage to own and serve artwork. Without a configured
public bucket, provider images stayed upstream passthrough URLs, sidecar/embedded/generated
artwork was inconsistently available, and the upload surfaces (library posters, collection
images, avatars, branding) were disabled entirely. A single-node installation had no
first-party durable artwork origin, and a lost or unreachable store meant broken images.
Approach
Implements the artwork storage and delivery spec developed with the maintainer (design
summary below; durable contracts are committed in
docs/architecture/artwork-storage.md).Four concerns are separated: source, canonical store, client delivery, and cache.
internal/artworkstore): one contract with a confined, atomiclocal-filesystem backend and the existing S3 client as an adapter. Backend selection is
auto | local | s3with database pinning at first materialization — later config changesfail loudly toward the reconcile workflow instead of silently splitting a catalog across
stores. Store markers + mount sentinels distinguish a deleted owned root from a dropped
NAS mount.
artwork/v1): revisions are SHA-256 over theproduced variant set; immutable objects plus a canonical
manifest.jsonwritten last; anon-secret source-adoption index lets a copied tree be reused by another install without
re-downloading or re-encoding. No credentials, signatures, paths, or identity in the tree.
every backend. A missing object is detected at request time and served from the verified
provider/plugin source (SSRF-safe fetcher, singleflight, bounded emergency cache) or the
confined sidecar; durable deduplicated repair re-materializes it; a bundled placeholder
plus a persistent data-loss alert covers sources that no longer exist. Store health is a
five-state machine (
healthy/degraded/unavailable/empty_rebuilding/wrong_mount) withdebounced probes; transport failures are never treated as deletion evidence; destructive
GC pauses during outages; an emptied owned-local root rebuilds automatically.
byte-accurate inventory with resumable backfill; admin endpoints report unique physical
bytes and non-additive per-library referenced/exclusive/shared/reclaimable attribution;
safe purge is a dry-runnable, resumable admin job that transitions catalog references to
verified fallbacks before reference-aware GC, protects non-reconstructible art, and
replaces every inline prefix deletion (admin cleanup and scanner).
move onto the store contract with immutable content-addressed keys — none require S3.
one source,
image_sizeselects the variant inside the capability at mint, pre-rungrevisions serve the nearest narrower rung via manifest-aware selection (never treated as
missing), and both capability endpoints are test-pinned to the same ladder.
API changes (pre-lock v1 posture)
Artwork URL values change shape (target-bound signed capabilities); new endpoints:
GET /api/v1/artwork/{capability}/{variant},GET /api/v1/artwork-library/{identity},GET /api/v1/artwork/capability,GET|POST /api/v1/admin/artwork/storage[/refresh],POST /api/v1/admin/artwork/purge,POST /api/v1/admin/artwork/rebuild. New settings:artwork.storage_backend,artwork.local_path,artwork.remote_materialization,artwork.url_ttl. (Earlier revisions also addedartwork.delivery_policy,artwork.url_auth,artwork.local_ownership, andartwork.seed_adoption_grace;all four were removed in-branch after maintainer review — resilient delivery is the
only behavior, local roots use unified cautious semantics with an explicit admin
rebuild, and the seed adoption grace is a fixed 30 days. The capability endpoint
keeps
delivery_policy/delivery_modes/automatic_recoverypinned constant;removals are recorded in the v1-scope pre-lock table.) Client docs:
docs/artwork-api.md. No pre-lock removals: no existing response field was renamed orremoved (URL fields carry new opaque values; clients that treated them as opaque are
unaffected — see follow-ups for the root-relative caveat).
