EnqueueLadderBackfillbuildsall_candidatesfrom full scans ofmedia_items,media_item_localizations,seasons,season_localizations, andepisodes, filtered byLIKE '%://%'predicates that cannot use a b-tree index. The processor calls this once per 200-row batch until it returns 0, so a library with 100k eligible rows performs about 500 full sweeps of those tables during the one-shot pass.The pass runs once per ladder version and is bounded by
cacheMetadataImagesMaxRuntime, so this is not a correctness problem. Consider one of these to keep the sweep off the primary's hot path:

resolveLadderKeyruns inside the per-entry loop, so each entry that requests a newly added rung costs at least one sequentialObjectExistsround trip.

There was a problem hiding this comment.
When a large library cannot finish within the 10-minute runtime limit, the next scheduled invocation creates a later completedBefore; rows completed by the previous invocation then satisfy completed_at < $2 again. Because candidate ordering is deterministic, each invocation can repeatedly regenerate the same prefix and never reach later artwork. Persist a version-specific cutoff or cursor until the entire pass completes so interrupted and runtime-limited runs actually resume.

There was a problem hiding this comment.
For existing artwork sourced from file:// sidecars, this predicate excludes every row because nonProviderImageSchemesSQL contains file://%, even though the image-cache processor explicitly supports these sources. Such posters remain without the new w780 rung forever after the deployment is marked backfilled, so image_size=large always falls back to a narrower image unless an unrelated rescan requeues it.

For item, season, or episode details containing credits, only the top-level artwork is changed here; credit photo_url values still flow through fetchCredits → personCredits → PresignURL(..., "featured"), which never receives the requested size or rewrites a cached profile key. Thus image_size=small, large, or original produces a mixed-size response and contradicts the capability endpoint's advertised profile widths.

For GET /api/v1/catalog/audiobook-groups, this shared parser accepts and stores a valid image_size, but resolveAudiobookGroupPosterURLs still unconditionally converts every cover with cardThumbnailPath and resolves them using the card hint. Consequently this catalog browse surface returns w300 covers for medium, large, and original, even though invalid values are rejected and the images API documents size selection for catalog browse responses.

There was a problem hiding this comment.
When a list response requests a newly added rung and this process's existence cache is cold, the loop calls resolveLadderKey synchronously for every distinct image; a missing poster commonly costs one HEAD for w780 and another for w500. A 100-item browse after a restart can therefore perform roughly 200 network round trips serially before returning JSON, causing multi-second latency or request timeouts. Resolve these checks with bounded concurrency rather than serializing the entire batch.

There was a problem hiding this comment.
For Jellyfin image requests whose only constraint is MaxHeight between 780 and 1199, this new branch promotes the response to the large width rung. For a typical portrait poster, MaxHeight=900 now selects a 780px-wide image whose proportional height is well over 900px, so the compatibility endpoint no longer honors the caller's maximum dimension and transfers substantially more data than requested. Keep height-only constraints from selecting a width that can exceed them, or account for the artwork aspect ratio.

There was a problem hiding this comment.
When a ladder job exhausts its retry budget, MarkFailed parks it with a future next_attempt_at; this predicate then hides the row, allowing EnqueueLadderBackfill to return zero and the task to record the ladder version as complete. Because ordinary drains only claim queued rows and the recorded version prevents another ladder discovery pass, that artwork is never retried automatically after the cooldown and permanently lacks the new rung. Treat deferred failed candidates as unfinished, or otherwise arrange their later rediscovery before recording completion.

There was a problem hiding this comment.
During a rolling cluster upgrade, these backfill entries are ordinary shared image-cache jobs with no required ladder version, so a node still running the parent revision can claim one, regenerate only the old w500 variants, and mark it succeeded. The new node then sees the post-cutoff completion, eventually records ladder version 2 as fully backfilled, and leaves that artwork without w780/w1280 permanently. Tag ladder jobs with their required version or prevent pre-version workers from claiming them before recording deployment-wide completion.

There was a problem hiding this comment.
If a metadata refresh changes an artwork source while this pass is between its candidate SELECT and this upsert, inputs still contains the old source A; after the normal refresh enqueue writes source B, this requeueSucceeded upsert can overwrite that job back to A. The processor then notices that the target now references B and marks A skipped/succeeded, but the B job has been lost, leaving the old cached artwork served indefinitely because ordinary discovery excludes rows with a nonempty cached destination. Make the enqueue conditional on the target still referencing the captured source, or perform candidate selection and upsert atomically.

When multiple API nodes run the startup task, node A can enqueue and begin a backfill batch while node B performs this query; because queued and running rows match none of these branches, B receives zero candidates and records the deployment-wide ladder version as complete. If A then dies before processing that batch or reaching later pages, subsequent scheduled runs skip the pass permanently, leaving those images without the new rungs. Use a deployment-wide backfill lease or count another worker's queued/running rows as unfinished before recording completion.

On the Jellyfin person-image route, a request with MaxWidth or a fill dimension from 780 through 1199 now selects large, but handlePersonImage resolves the cached .../profile/original... path as image type poster. That produces a w780 key even though profile images generate only w500 and w300; the ladder fallback also deliberately ignores profile keys, so the handler serves a presigned URL for a nonexistent object. Resolve person photos with the profile image type so this range clamps to w500.

When an episode has no still, fallback.Path is normally the parent series backdrop, but this line rewrites it using the still ladder. With image_size=medium or large, that produces a nonexistent backdrop/w500 or backdrop/w780 key; the resolver will not fall back because neither is the newly added backdrop rung. Episode-list responses therefore contain broken image URLs whenever they use a series backdrop fallback. Derive the image type from the selected path, as the other backdrop helpers do.

During a rolling cluster upgrade, this records the deployment-wide version immediately after a point-in-time remainder check, even though an old node may subsequently finish an ordinary scan or refresh job and publish artwork containing only the old ladder. Since later runs skip discovery once this state is set, that artwork remains permanently on the narrower fallback ladder. Fresh evidence in the final code is that the manifest-based remainder check fixes old workers completing an in-flight backfill job, but SetBackfilled still has no worker-version fence or post-rollout confirmation.

… seam Posters and stills gain w780, logos gain w1280, so a client can ask for artwork wider than the pre-existing default without falling back to the original. Cast/crew profiles deliberately stay at w500/w300. The new internal/imagesize package owns the client-facing size contract in one leaf package: the image_size parameter, the four sizes, and the mapping from a size to a cached variant. Small and large are derived from artworkkey.VariantWidths; medium is pinned to the pre-image_size default so an absent parameter and an explicit medium agree. LadderVersion records the shape of the ladder so a later backfill can tell that existing artwork predates the new rungs. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…rge bucket Adds GET /api/v1/images/capability so a client can discover the image_size parameter and the pixel width behind each size instead of hardcoding them; the widths are derived from the live variant ladder. Jellyfin clients asking for 780-1199px now get the new wide rung rather than being rounded down to the default. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Catalog reads, item and watch detail, seasons and episodes, and the home and library section endpoints accept image_size=small|medium|large|original. The size applies to the whole response so a client never mixes resolutions within one screen, and it overrides the per-context defaults including the Continue Watching w1280 backdrop. Without the parameter every path is byte-identical to before, which is what every existing client sends. An unrecognized value is a 400 rather than a silent fallback to the default size. The parsed size rides on AccessFilter to reach the detail service helpers that already carry it; imagesize still owns every decision. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…s missing Artwork cached before the ladder gained w780 posters/stills and w1280 logos has no object at those keys, so a client asking for the large size would get a 404 until the backfill catches up. The cached-key resolver now checks whether a newly-added rung exists and walks down to one that does, ending at the original. Existence answers are cached — a day for present, fifteen minutes for absent — so the check costs at most one HEAD per key per window. A check that errors presigns the requested key optimistically and caches nothing, so brief storage trouble cannot pin everyone to a narrow image. URLs served from a fallback get a shortened lifetime so the real rung is picked up promptly. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…sion Artwork cached before the ladder grew has no object at the new rungs, so clients asking for the large size fall back until it is regenerated. A one-shot pass re-enqueues already-cached poster, still, and logo artwork in bounded batches after the ordinary queue drains, and records the ladder version it finished in a new singleton table. Interrupting it is safe: the pass resumes on the next scheduled run and only a complete pass records the version. Re-running costs the source download — the cacher skips uploading variants whose objects already match. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Response builders took the request and re-parsed image_size per item. They now take the size the entrypoint already validated, so what a response renders cannot drift from what was checked. accessFilterOrDeny carries it too, which is what the episode and season paths read. Deletes three response helpers the compiler proved unreachable (toEpisodeResponse, toEpisodeResponseWithFallback, toSeasonResponse). They were already dead; the live paths go through episodeResponseShell and toSeasonResponseFromEpisodes. Also folds the capability handler's width parsing into an exported imagesize.VariantWidthPx rather than a second copy of the same rule. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The personal lists hardcoded their artwork widths, so a client that asked every other list endpoint for a size got its preference ignored on the three screens users open most. They now take the same parameter with the same semantics: validated once per request with a 400 on a bad value, and applied to every image in the response. Sending nothing is byte-identical to before, including the deliberate asymmetry between the featured poster and the card backdrop. Episode entries resolve their still into the backdrop slot, so that path follows the still ladder rather than building a backdrop-width key that was never generated. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Plugin-resolved artwork collapsed large onto "featured", so an item whose poster is hosted by a metadata plugin ignored the size a client asked for while a cached one honored it. PluginVariant now returns "large". No capability gate: the SDK's variant field is an open string and first-party plugins fall back gracefully on a name they do not recognize — tmdb and metadb to the original, tvdb to full art — so a plugin built before this tier still returns a usable image. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
CI's golangci-lint flagged eleven repeated string literals on this branch. Rather than silence them one by one, the two vocabularies they belong to now have names: artworkkey owns the image types its ladder is keyed by, and imagesize owns the plugin-facing variant hints. jellycompat expresses its size buckets with the imagesize constants, which is what they already were. The ladder fallback stops spelling out the widths it checks. Each type that gained a rung gained its widest one, so the check reads that back off the ladder and cannot drift from artworkkey.VariantWidths. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ides A card's backdrop slot does not always hold a backdrop — an episode row puts its still there. The card paths passed "backdrop" regardless, so a medium or large request built a still/w1920 key the cache never generates and the URL 404'd. The slot now reads the type back off the key, as the featured backdrop path already did. Cast and crew headshots honored no size at all: they presigned the stored key with a fixed hint. They now follow the profile ladder when a size is asked for, and are byte-identical when one is not. Also makes the cache task's progress monotone. A ladder pass in the same execution reported 100 for the drain and then restarted at 0, which reads as a failed-and-retrying task; the two phases now own ascending halves of the bar. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…b state The sweep asked its own job table whether it was finished, and that answer is wrong in four ways on a cluster. A bounded run recomputed its cutoff each time, so a time-limited pass re-selected rows the previous one had completed and could grind the same prefix forever. A node starting while another node's batch was in flight saw nothing to do and recorded the version done — and if that other node then died, the pass never resumed. During a rolling upgrade an old-revision node could claim a job, write only the old rungs, and mark it succeeded. And a job that exhausted its retries was parked out of view, which also read as done. Completion is now a question about storage: is any cached artwork still missing the rung its type gained? It is answered from the artwork revision manifest, which the cacher rewrites on every re-cache. All four failures collapse — in each one the manifest is unchanged, so the row stays a candidate and is simply picked up next time. The cutoff is gone entirely, and the enqueue's dedup join goes back to being only what it says it is. Sidecar (file://) artwork joins the sweep: the processor re-caches local sources, so excluding them stripped those items of the new rungs for good. Because completion is now measured against artwork that may be unregenerable, the pass is paced rather than run every scheduler tick. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
A cold existence cache made every image in a list response wait on up to two serial HEADs before the JSON could be written; a hundred-item browse page turned that into seconds of latency in front of the response. The ladder walk now runs for the whole batch with bounded concurrency, and only for keys that can actually be missing — every other rung resolves without touching storage. Presigning stays serial because it is local signing work, not a round trip. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Three surfaces disagreed with the rest of the API. /catalog/audiobook-groups validated image_size and then ignored it, hardcoding the card variant. jellycompat promoted a request to the large bucket on a height-only constraint, but large names a WIDTH rung, so a portrait poster asked for at MaxHeight=900 came back far taller than that. And jellycompat resolved person headshots as posters, which since posters gained w780 meant building a profile/w780 key that is never generated — a dead URL the ladder fallback deliberately will not rescue.

When upgrading a library whose audiobook or ebook cover was cached directly from embedded or sidecar bytes, poster_source_path is empty because those scanner paths persist only poster_path; this predicate therefore excludes the artwork entirely. Unlike the earlier file:// case, these covers have no source URI, and subsequent scans skip existing or thumbhash-identical covers, so HasLadderBackfillRemaining can report completion while their w780 object is still absent and image_size=large falls back to w500 indefinitely. Include local/audiobooks and local/ebooks posters through a regeneration path that can read their original cached object or re-extract the source.

For a Jellyfin Logo request with MaxWidth from 780 through 1199, this branch returns large; imageURLForItem then resolves that size on the logo ladder, where large is w1280. A client asking for at most 780px can therefore receive a 1280px logo, whereas the previous medium mapping returned w500. Make the promotion threshold image-type-aware, or select the widest available rung that does not exceed the requested maximum.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
The trigger takes the singleton row lock before it checks the version, so it serializes every artwork publication permanently.
SELECT ... FOR UPDATE on image_ladder_backfill_state runs on every insert or update that publishes a local cached path. The lock is held until the surrounding transaction commits. Two effects follow:
- Concurrent transactions that publish artwork (scan ingest, image cache workers) block on one row, so artwork publication is serialized deployment-wide.
ConfirmBackfilledlocks the same row and then runs the catalog-wide candidate scan while holding it (internal/metadata/image_ladder_backfill_state_repo.go lines 96-112). Every publisher blocks for the duration of that scan.
The version check at line 53 does not limit this cost, because the lock is already taken. The trigger stays installed after the ladder reaches v2, so the serialization is permanent, not a one-time migration cost.
Read the version without the lock first and return early when it is already at or above 2. Take FOR UPDATE only on the path that can reopen the version.

There was a problem hiding this comment.
For requests that specify only MaxHeight or FillHeight between 780 and 1199, this documentation promises large, but compatRequestImageSize promotes to large only when maxWidthDim reaches 780; for example, MaxHeight=900 returns medium. Document the width- and height-based behavior separately so Jellyfin client authors do not rely on a mapping the server deliberately avoids.

There was a problem hiding this comment.
Because this shared access helper is also used by non-artwork operations such as POST /watched/{id} and POST /items/{id}/trailers/refresh, those routes now return 400 invalid_image_size when an irrelevant malformed parameter is present. That contradicts the documented contract that surfaces outside the listed artwork responses ignore image_size; validate it only in image-bearing entrypoints or separate access resolution from image-size parsing.

There was a problem hiding this comment.
When the ordinary image queue remains busy for the full 10-minute drain limit, DrainUntilIdle reports RuntimeLimited in its stats but executeMetadataImages discards those stats and returns nil, so this branch immediately starts the ladder pass anyway. RunLadderBackfill then enqueues another 200 regeneration jobs into an already-backed-up queue, allowing maintenance work to delay newer scan and refresh artwork on sustained-load deployments despite the stated drain-first ordering. Preserve the drain outcome and defer the ladder phase unless the ordinary queue actually reached idle.

* 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.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* 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.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
* 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.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
* 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.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
* 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.

* 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.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* 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.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* feat(streamtelemetry): observe every route family by default
The staged per-family rollout set (native, proxy, transcode_node) is removed
by owner decision: SILO_STREAM_TELEMETRY_FAMILIES left unset now observes all
five declared families (native, jellycompat, proxy, abs, transcode_node)
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

* 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.

* fix(playback): validate realtime command ownership before consuming it
Review fixes: a realtime result naming another session's command is now
rejected before the tracker deadline is canceled or the record dropped; the
concurrent-scan test waits on observable state (a gated fake ffmpeg) instead
of a fixed sleep; changelog wording no longer overclaims verdict permanence.

* fix(playback): close copy-safety races in replan commits, transport stops, and reconstruction
Review round two: sessions the notifier could not classify mid-replan-commit
stay eligible for the post-settle sweep instead of being marked handled;
WatchTransportStop returns an already-closed channel for a session stopped
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.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* fix(playback): gate copy-unsafe revivals before reconstruction and per file generation
Round three review fixes: the reconstruction verdict gate moves ahead of
session registration in loadTranscodeServeSession, so refused revivals cover
the remote-node proxy branch and can no longer poison stream admission with a
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.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* 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.

* fix(sections): enforce disabled episode hydration scope
* fix(scanner): scope file reconciliation to changed path

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.

* docs: remove committed tone-map implementation plan
Plans in docs/superpowers/ are working artifacts and are never committed
(AGENTS.md); the directory is gitignored and main deleted the rest of it.
Most of what the plan described is already covered by this branch's
playback-protocol-v3.md updates — capability advertisement, the tone-map
smoke probe, Dolby Vision base-layer classification, the degradation
warning, the quality ladder and the terminal reason. Five durable rules
were not, so they are distilled into a new "Tone-map execution integrity"
section rather than lost with the plan: what a frozen recipe must carry and
what sidecar-only replan equality therefore compares; the executor-side
source re-verification before every tone-map run and its permanent-versus-
transient split; why a tone-map stream token uses the transcode_tonemap_v1
discriminator; the crash-ordered attestation receipt that makes a remote
prepared artifact fail closed at delivery; and why ambiguous Dolby Vision
provenance is refused rather than inferred.

* test(playback): widen gpudetect probe deadline to deflake capability test
TestResolveHWAccelWithFFmpegContextHonorsCallerDeadline gave the probe a
20ms caller deadline. That budget has to cover the fake sysfs walk in
listRenderDevices before the probe is even reached, and when the test runs
after the rest of the package that walk is cold: the deadline expires
first, exec.CommandContext declines to start the process, and the test
fails reading a probe log the fake FFmpeg never wrote. It passed only when
run alone.
Both deadlines in the test move to 60ms. That is still far below the 200ms
per-command timeout the test's own `elapsed >= 150ms` assertion exists to
distinguish the caller deadline from, so the behavior under test is
unchanged — only the headroom is.

* fix(jellycompat): default omitted IsRequired to true and evaluate real track data
Jellyfin's ProfileCondition defaults IsRequired to true when the JSON key

interlacing, frame rate, video/audio bitrate, sample rate, and audio
profile from scanned track data so those conditions evaluate against real
values instead of falling through the unknown-property path, and derive
IsAnamorphic from display-vs-storage aspect ratio in both condition
evaluation and the media-stream DTO instead of hardcoding false.

* fix(jellycompat): let unknown condition values honor IsRequired
Legacy condition values (video level, ref frames, dimensions, bit depth,
audio channels, video profile) were always inserted even when unknown, so
numeric comparisons failed regardless of IsRequired — an unprobed level
(0 or ffprobe's -99 sentinel) failed an optional VideoLevel cap and could
eliminate every playback path for 4K media with 4K transcoding disabled.
Insert them only when known so unknowns fall through to the IsRequired
path like the newer values, and expose IsAVC to the evaluator to match
the media-stream DTO.

* fix(playback): clean stale copy output on recipe-changing restarts so the throttler cannot deadlock a tone-map switch
A copy generation produces segments at disk speed and races hundreds of
segments ahead of the client, and a restart only cleaned the shared output
directory when the new target was itself copy — so a copy-to-tone-map switch
left the copy manifest and its segments in place. SegmentProgress read that
stale manifest as the produced head while restart reset LastRequestedSegment,
so the throttler saw a huge bogus gap and paused the fresh ffmpeg before it
wrote its first segment; the manifest then never refreshed, the gap never
shrank, and the stream stayed paused until the user seeked. Restarts now clean
the manifest and the segments at or after the restart point whenever the
emitted recipe changes (video codec, bitstream filter, tone-map mode or filter,
hardware backend), keeping segment reuse only for same-recipe backward seeks.
As defense in depth the throttler stamps each ffmpeg generation and refuses to
pause on — and resumes from — produced output older than the current process.

* fix(web): resume playback after a server-invalidated plan swaps the transport
A plan revision rebuilds the transport by tearing the previous source down with
`video.load()` in the outgoing effect's cleanup, and the media element load
algorithm is required to reject any play that is still pending with an
AbortError. The startup path latched `autoplayStarted` and dropped its readiness
listeners before awaiting `play()`, so that first rejection was swallowed by a
bare `.catch` and nothing ever tried again: the element sat paused on a healthy
buffer, the engine stopped fetching once it hit `maxBufferLength`, and the server
throttler paused the encoder behind a client that had gone silent. Autoplay is
now only latched once `play()` resolves, a rejection retries on a short timer as
well as on the next readiness event, and exhausting the budget logs the reason
and settles into a paused player with working controls instead of a dead one.
Direct play goes through the same readiness gate rather than calling `play()`
against a src still at HAVE_NOTHING.

* feat(images): client-selectable artwork size via image_size (#742)
* feat(artwork): add a wide rung to the variant ladder and an imagesize seam
Posters and stills gain w780, logos gain w1280, so a client can ask for
artwork wider than the pre-existing default without falling back to the
original. Cast/crew profiles deliberately stay at w500/w300.
The new internal/imagesize package owns the client-facing size contract in
one leaf package: the image_size parameter, the four sizes, and the mapping
from a size to a cached variant. Small and large are derived from
artworkkey.VariantWidths; medium is pinned to the pre-image_size default so
an absent parameter and an explicit medium agree.
LadderVersion records the shape of the ladder so a later backfill can tell
that existing artwork predates the new rungs.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* feat(api): expose the image size capability and give jellycompat a large bucket
Adds GET /api/v1/images/capability so a client can discover the image_size
parameter and the pixel width behind each size instead of hardcoding them;
the widths are derived from the live variant ladder.
Jellyfin clients asking for 780-1199px now get the new wide rung rather
than being rounded down to the default.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* feat(api): let clients pick an artwork size with image_size
Catalog reads, item and watch detail, seasons and episodes, and the home
and library section endpoints accept image_size=small|medium|large|original.
The size applies to the whole response so a client never mixes resolutions
within one screen, and it overrides the per-context defaults including the
Continue Watching w1280 backdrop.
Without the parameter every path is byte-identical to before, which is what
every existing client sends. An unrecognized value is a 400 rather than a
silent fallback to the default size.
The parsed size rides on AccessFilter to reach the detail service helpers
that already carry it; imagesize still owns every decision.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* feat(metadata): fall back to a narrower artwork rung when a new one is missing
Artwork cached before the ladder gained w780 posters/stills and w1280 logos
has no object at those keys, so a client asking for the large size would get
a 404 until the backfill catches up. The cached-key resolver now checks
whether a newly-added rung exists and walks down to one that does, ending at
the original.
Existence answers are cached — a day for present, fifteen minutes for absent
— so the check costs at most one HEAD per key per window. A check that errors
presigns the requested key optimistically and caches nothing, so brief
storage trouble cannot pin everyone to a narrow image. URLs served from a
fallback get a shortened lifetime so the real rung is picked up promptly.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* feat(metadata): regenerate cached artwork once per variant ladder version
Artwork cached before the ladder grew has no object at the new rungs, so
clients asking for the large size fall back until it is regenerated. A
one-shot pass re-enqueues already-cached poster, still, and logo artwork in
bounded batches after the ordinary queue drains, and records the ladder
version it finished in a new singleton table.
Interrupting it is safe: the pass resumes on the next scheduled run and only
a complete pass records the version. Re-running costs the source download —
the cacher skips uploading variants whose objects already match.

* test(api): record the images capability route in the manifest
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* refactor(api): thread the validated image size instead of re-reading it
Response builders took the request and re-parsed image_size per item. They
now take the size the entrypoint already validated, so what a response
renders cannot drift from what was checked. accessFilterOrDeny carries it
too, which is what the episode and season paths read.
Deletes three response helpers the compiler proved unreachable
(toEpisodeResponse, toEpisodeResponseWithFallback, toSeasonResponse). They
were already dead; the live paths go through episodeResponseShell and
toSeasonResponseFromEpisodes.
Also folds the capability handler's width parsing into an exported
imagesize.VariantWidthPx rather than a second copy of the same rule.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* feat(api): honor image_size on favorites, watchlist, and history
The personal lists hardcoded their artwork widths, so a client that asked
every other list endpoint for a size got its preference ignored on the three
screens users open most.
They now take the same parameter with the same semantics: validated once per
request with a 400 on a bad value, and applied to every image in the
response. Sending nothing is byte-identical to before, including the
deliberate asymmetry between the featured poster and the card backdrop.
Episode entries resolve their still into the backdrop slot, so that path
follows the still ladder rather than building a backdrop-width key that was
never generated.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* feat(images): forward the large tier to plugin image resolvers
Plugin-resolved artwork collapsed large onto "featured", so an item whose
poster is hosted by a metadata plugin ignored the size a client asked for
while a cached one honored it.
PluginVariant now returns "large". No capability gate: the SDK's variant
field is an open string and first-party plugins fall back gracefully on a
name they do not recognize — tmdb and metadb to the original, tvdb to full
art — so a plugin built before this tier still returns a usable image.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* refactor(images): name the image-type and variant vocabularies
CI's golangci-lint flagged eleven repeated string literals on this branch.
Rather than silence them one by one, the two vocabularies they belong to now
have names: artworkkey owns the image types its ladder is keyed by, and
imagesize owns the plugin-facing variant hints. jellycompat expresses its
size buckets with the imagesize constants, which is what they already were.
The ladder fallback stops spelling out the widths it checks. Each type that
gained a rung gained its widest one, so the check reads that back off the
ladder and cannot drift from artworkkey.VariantWidths.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* fix(images): resolve card backdrops on the ladder the path actually rides
A card's backdrop slot does not always hold a backdrop — an episode row puts
its still there. The card paths passed "backdrop" regardless, so a medium or
large request built a still/w1920 key the cache never generates and the URL
404'd. The slot now reads the type back off the key, as the featured backdrop
path already did.
Cast and crew headshots honored no size at all: they presigned the stored key
with a fixed hint. They now follow the profile ladder when a size is asked
for, and are byte-identical when one is not.
Also makes the cache task's progress monotone. A ladder pass in the same
execution reported 100 for the drain and then restarted at 0, which reads as
a failed-and-retrying task; the two phases now own ascending halves of the
bar.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* fix(metadata): decide ladder backfill completion from artwork, not job state
The sweep asked its own job table whether it was finished, and that answer is
wrong in four ways on a cluster. A bounded run recomputed its cutoff each
time, so a time-limited pass re-selected rows the previous one had completed
and could grind the same prefix forever. A node starting while another node's
batch was in flight saw nothing to do and recorded the version done — and if
that other node then died, the pass never resumed. During a rolling upgrade an
old-revision node could claim a job, write only the old rungs, and mark it
succeeded. And a job that exhausted its retries was parked out of view, which
also read as done.
Completion is now a question about storage: is any cached artwork still
missing the rung its type gained? It is answered from the artwork revision
manifest, which the cacher rewrites on every re-cache. All four failures
collapse — in each one the manifest is unchanged, so the row stays a
candidate and is simply picked up next time. The cutoff is gone entirely, and
the enqueue's dedup join goes back to being only what it says it is.
Sidecar (file://) artwork joins the sweep: the processor re-caches local
sources, so excluding them stripped those items of the new rungs for good.
Because completion is now measured against artwork that may be
unregenerable, the pass is paced rather than run every scheduler tick.

* perf(metadata): resolve artwork ladder checks for a batch concurrently
A cold existence cache made every image in a list response wait on up to two
serial HEADs before the JSON could be written; a hundred-item browse page
turned that into seconds of latency in front of the response.
The ladder walk now runs for the whole batch with bounded concurrency, and
only for keys that can actually be missing — every other rung resolves
without touching storage. Presigning stays serial because it is local signing
work, not a round trip.

* fix(images): honor image_size on audiobook groups and person artwork
Three surfaces disagreed with the rest of the API. /catalog/audiobook-groups
validated image_size and then ignored it, hardcoding the card variant.
jellycompat promoted a request to the large bucket on a height-only
constraint, but large names a WIDTH rung, so a portrait poster asked for at
MaxHeight=900 came back far taller than that. And jellycompat resolved person
headshots as posters, which since posters gained w780 meant building a
profile/w780 key that is never generated — a dead URL the ladder fallback
deliberately will not rescue.

With allow_4k_transcode off, the alternate-file fallback only excluded

offered as the fallback and refused for the same policy reason. The 4K
label test now lives in one exported helper (Is4KMediaFileV3) shared by
the planner and the fallback picker.
The web player replaced the server's terminal.message with generic copy
for no_alternate_version and the transcode-failure reasons; policy
refusals such as "A lower-resolution source is required because 4K
transcoding is disabled." now reach the viewer verbatim, with the old
generic sentence kept as the fallback for an absent message.

The watch-progress bar sat flush against the artwork's bottom edge; with

stray white edge on the card. Inset it into a rounded pill across all
card/thumbnail surfaces so it reads as deliberate UI.

below lg so bottom-justified content grows the hero instead of
overflowing out the top under the floating back button. The player
seek bar shows its thumb and thicker track on coarse pointers, where
hover reveal never fires.

and detail, but search and episode rails still keyed off episode_libraries.
Episodes whose files lived only in an enabled library kept appearing, then
404'd on open. Apply the same parent-series allow/deny predicates those
detail and playback paths already use.

Light-theme users previously got the white-text wordmark, which is
invisible on light surfaces. Themes now declare an appearance, SiloBrand
picks the bundled dark-text wordmark on light themes, and admins can
upload optional light-theme variants of the custom wordmark and mark
(new wordmark_light/mark_light asset kinds, additive API fields).

* feat(web): replace touch card overlays with long-press action sheet
On touch devices media cards showed every overlay control at rest —
center play button, watched/favorite quick actions, and the three-dot
menu — cluttering the artwork. Hide them at rest and open the same
action model from a 500ms long press as a bottom sheet instead,
matching the native clients. Hover reveal is unchanged for fine
pointers, and keyboard focus still reveals the controls on every
device.

* fix(catalog): bound search outbox retention
* feat(taskmanager): add bounded task history retention cleanup
- Prune execution history by age and per-task retention limits
- Coordinate cleanup across nodes with a PostgreSQL advisory lock
- Register the scheduled cleanup task and add coverage
* refactor(taskmanager): address review findings on history retention
Rework the task history retention cleanup added in this PR after review.
- Replace the whole-table window ranking in the prune query with a
per-task-key boundary design. Each key resolves its newest row and its
keep-boundary row from idx_task_executions_key_completed, and deletes run
against a tuple-comparison predicate that is provably equivalent to the
previous recent_rank CTE (pinned by a test that diffs both doomed sets).
A run with nothing to delete no longer sorts the entire table, and no
longer does so once per batch. No new migration.
- Report LimitReached only when doomed work actually remains. Loop
exhaustion alone used to claim a truncated run whenever the doomed count
was an exact multiple of batchSize.
- Extract the session-level advisory lock into internal/database/pglock and
use it from both Prune and the catalog search indexer, deleting
SearchIndexAdvisoryLock. The shared helper hijacks and closes the
connection whenever an unlock cannot be confirmed, which also fixes the
catalog helper's unconditional Release on unlock failure.
- Drive retention from server settings (taskmanager.history_retention_days,
default 30; taskmanager.history_keep_per_task, default 1000) the way the
activity and operational log cleanups do: seeded at boot, read per
Execute, out-of-range values falling back to the defaults. Batch geometry
stays a compile-time constant.
- Log an info line when a run is skipped because another node holds the
lock, so a skip is visible outside result_data.
- Drop the taskHistoryCleanupResult mirror struct and tag
taskmanager.HistoryPruneResult directly; drop the nil-progress guard and
the unreachable limit validation in Prune; unexport taskHistoryPruner.
- Rewrite the repository tests against the migrated SILO_TEST_DATABASE_URL
database instead of a hand-copied throwaway schema, with unique task keys
and cleanup deletes, and cover the keepPerTask boundary, tie-breaks,
cutoff rank-1 preservation, and the exact-multiple LimitReached case.

* feat(catalog): persist Watchlist and Favorites browse sort per profile
Sort choices made while browsing a library or user collection already
survive leaving and re-entering the view, but the two personal lists did
not: Watchlist and Favorites reset to their default order on every visit.
Widen the existing profile-scoped sort preference storage to cover them
instead of adding a parallel mechanism. `collection_kind` gains
`watchlist` and `favorites`; because neither has a collection resource id
of its own, both store under the sentinel `collection_id` "personal".
Personal lists validate against the same non-personalized vocabulary the
live personal browse accepts (NormalizePersonalSourceSort), so `progress`,
`date_viewed`, `plays`, `relevance`, and `rand…

…delivery Rebasing onto main brought in the image_size feature (#742), whose ladder, resolver, and threading changes landed in files this branch redesigned. Restores the w780 poster/still and w1280 logo rungs derived from the shared variant ladder, selects the mapped variant inside the target capability at mint time, serves pre-rung revisions from the nearest narrower rung via manifest-aware selection (never treating a merely-narrower revision as missing), keeps the existence-probe cache for manifest-less legacy keys only, restores the Jellyfin wide-rung bucket, and pins both capability endpoints to one ladder.

Problem
On large TVs, posters and backdrops look blurry. The v1 API hardcodes which artwork variant every client receives — w300 cards and w500 posters regardless of screen — and the stored variant ladder tops out at w500 for posters, stills, and logos. A 4K TV upscaling a 500px poster is exactly the reported blur. Clients had no way to ask for more, and nothing larger existed to serve.
Approach
Two halves, one contract:
internal/artworkkey, the single source of truth for generation, key expansion, and GC) gains w780 for posters and stills and w1280 for logos; backdrops already had w1920. A newLadderVersionconstant triggers a one-shot, crash-safe background regeneration pass (singleton state table, bounded batches after the scheduled image-cache drain) so existing libraries gain the new rungs without operator action. Until a rung is generated, a presign-time S3 existence check transparently serves the next lower rung (exists cached 24h, missing 15m, errors optimistic and uncached, fallback URL cache clamped so the real rung is picked up promptly).internal/imagesizeowns the size vocabulary and every (image type, size) → variant decision. Catalog, detail, seasons/episodes, sections, and the personal lists (favorites/watchlist/history) acceptimage_size=small|medium|large|original; the server bakes the chosen variant into the URLs it returns. An absent parameter is byte-identical to today's behavior (pinned by regression tests); an invalid value is a 400.GET /api/v1/images/capabilityadvertises the parameter, sizes, and per-type widths live from the ladder, following the existing capability-endpoint pattern.jellycompat parity: Jellyfin-protocol clients don't send

This PR supersedes and closes #336 by @raiden202, whose approach it deliberately carries forward: the ladder-rung additions for stills and logos and, in particular, the S3 existence-check fallback with asymmetric TTLs originated there. This re-implementation extends the idea to posters (the most visible blur), adds the client-facing
image_sizeparameter and capability endpoint, and adds the automatic backfill. Credit to @raiden202 for identifying the problem and the fallback design.Coordinated client work
