9ce51cf575 perf(artwork): fetch only IDs for backfill enumeration
Backfill enumerated every album, artist, playlist and radio via GetAll
and mapped out just the ID. GetAll materializes full entities (library
joins, participant/stats/tags JSON, annotation, artwork hydration), so on
a large library it loaded tens of thousands of heavy structs only to read
one field each — spiking transient RSS to ~1GB during the one-time
upgrade backfill, a memory risk on small NAS/Pi hardware.

Add GetAllIDs to the album, artist, playlist and radio repositories: it
reuses each repo's base row-set filter (library visibility, artist
content join, playlist userFilter) but projects only id, skipping the
heavy columns and post-processing. A per-repo parity test asserts
GetAllIDs returns exactly the same id set as GetAll.

Verified on a 727MB / 29k-artist production DB copy: peak RSS during
backfill dropped from ~1012MB to ~89MB, file descriptors flat, same
36,138 items enqueued.

bab9b5cd3a fix(artwork): purge dangling queue rows and guard concurrent re-enqueues
Queue rows for deleted entities failed forever (Get -> ErrNotFound -> failed -> capped retries, unbounded). Add ArtworkQueueRepository.PurgeDangling, called from Prune next to the item_artwork purge. Separately, the found/absent path unconditionally deleted the dequeued row, erasing a concurrent scan re-enqueue; switch to DeleteIfUnchanged, which deletes only while retry_at still matches the dequeued value (verified retry_at is the column an Enqueue upsert resets).

feat(jellyfin): filter items by year and record label (#5817)
* feat(persistence): add AlbumRepository.GetYears for distinct album years

* test(persistence): verify GetYears de-duplicates repeated years

Regression test that adds two albums with the same non-zero max_year
(2005) and verifies that GetYears() returns that year exactly once,
ensuring the SQL DISTINCT clause is applied correctly. Catches any
future removal of DISTINCT from the GetYears query.

* feat(jellyfin): add legacy /Items/Filters endpoint (genres + years)

* feat(jellyfin): add /Studios endpoint from record label tags

* refactor(persistence): drop duplicate columns in tagRepository.GetAll

* fix(jellyfin): exclude missing albums from filter years

GetYears only filtered max_year > 0, so albums whose files were all removed
(missing=true, kept when Scanner.PurgeMissing=never) contributed stale years
to /Items/Filters. Filter them out like the normal album listings do. Also
return an empty slice from the MockAlbumRepo to match the real repository.

* feat(jellyfin): filter /Items by Years=

* feat(jellyfin): filter /Items by StudioIds= (record labels)

* feat(jellyfin): scope filter and studio lists to ParentId library

* refactor(jellyfin): extract parentIDScope and libraryScopeFilter helpers

Collapse the three inline resolveLibraryScope(dto.DecodeID(parentid)) call
sites and the duplicated empty-scope guard into two small helpers, so the
empty-scope=unrestricted contract lives in one place. Reuse the existing
names() helper in the Years= e2e test.

* feat(jellyfin): expose record labels as album Studios

Add a Studios field to the album BaseItemDto, populated from the record-label
tags and gated behind Fields=Studios (matching Jellyfin's ItemFields
convention). Studio ids reuse the record-label tag identity, so they round-trip
with the /Studios list and the StudioIds= filter. Real Jellyfin leaves Studios
empty for music; Feishin reads it as the album's record label.

feat(server): expose album-level ReplayGain in albums (#5816)
* feat(model): aggregate album ReplayGain in ToAlbum

* feat(db): add nullable album ReplayGain columns with backfill

* feat(persistence): persist album ReplayGain fields

* feat(jellyfin): expose album NormalizationGain from ReplayGain

* refactor(model): lazy-init mostFrequentPtr map; clean up RG test rows

* fix(db): backfill album ReplayGain with most-frequent value, not max

A plain max() picked a minority outlier that diverged from MediaFiles.ToAlbum
(which uses the most-frequent value), and GetTouchedAlbums never re-derives an
unchanged album, so the wrong value would persist. Reproduce the modal
aggregation via grouped CTEs, which also groups media_file once instead of a
per-album correlated scan.

* refactor(model): return an owned pointer from mostFrequentPtr

Avoid aliasing a MediaFile field so the resulting Album is independent of the
source slice.

feat(ui): playlist favourites (heart, list filter, sidebar favourites-only toggle) (#5805)
* feat(playlists): register starred REST filter on playlist repository

* feat(ui): add persisted sidebarPlaylistsOnlyFavourites setting

* feat(ui): playlist favourites heart column and list filter

* feat(ui): favourite heart on playlist details header

* feat(ui): sidebar favourites-only playlist toggle with live refresh

* fix(playlists): qualify id in REST filter to avoid ambiguous column

The annotation join in selectPlaylist made a bare id filter ambiguous, so
GET /api/playlist?id=X (react-admin getMany, used by the sidebar refetch and
useResourceRefresh) failed with 'ambiguous column name: id'. Register
idFilter("playlist") like the album/artist/mediafile repos.

* fix(ui): refresh favourites sidebar on local star toggle

The SSE broker skips the client that originated a star, so the acting client
never got the refreshResource echo and its favourites-only sidebar went stale.
Key the sidebar query on a fingerprint of locally-known starred playlists so a
star/unstar on this client refetches; SSE still covers other clients.

* style(ui): prettier-format PlaylistsSubMenu test

* feat(ui): refine playlist favourites layout

- Move the favourite heart column to just before the edit button
- Space the Playlists sidebar header text from its action icons
- Use a list icon instead of a cog for the playlist-management action

* feat(ui): make the playlist Favourite column toggleable

Move the heart into the toggleable fields map so users can show/hide it
from the column selector like the other optional columns, keeping it last
so it stays just before the edit button.

* refactor(ui): memoize sidebar star fingerprint and gate it on favourites-only

- Derive starFingerprint via useMemo on the playlist data reference instead
  of recomputing sort/join inside useSelector on every app-wide dispatch.
- Only include the fingerprint in the query payload when favourites-only is
  on, so a star toggle no longer refetches the sidebar when it shows all
  playlists.

* fix(ui): don't refetch favourites sidebar on SSE events when showing all

When favourites-only is off the sidebar shows every playlist, so a star
event from another client changes nothing visible. Gate the SSE-driven
refresh counter (and its payload key) on onlyFavourites so the sidebar no
longer redraws on unrelated playlist star events.

* fix(ui): address automated review feedback on playlist favourites

- Ignore a persisted favourites-only preference when EnableFavourites is off,
  so disabling the feature later can't strand a filtered sidebar (Codex P2).
- Make PlaylistLove's datagrid header props explicit (source/sortable via
  defaultProps, className forwarded) instead of relying on prop pass-through.
- Add aria-label to the SubMenu secondary action button.
- Cover the PlaylistLove list column with tests (Codex P1).

  the window between an edit and the next owner read
- Parse negative d/w durations so they are rejected with the consistent
  "negative duration" error instead of "unknown unit"
- Quote input in the negative-duration error, matching the parse error
- Gate per-playlist RefreshDelay behind IsSmartPlaylist, matching its doc

fix(jellyfin): close the unbounded playlist and search paths left by #5783 (#5784)
* fix(jellyfin): stream playlist tracks instead of loading every one

PR #5783 left the playlist paths materializing: all three loaded every track
of a playlist, whatever the client asked for. A playlist can be the whole
library — a smart playlist matching everything — so this is the same OOM class
that PR fixed for the other collections. Measured on a 96k-track smart playlist,
/Items?ParentId=<playlist>&Limit=10 peaked at 1.3GB to return ten tracks.

Playlist tracks now stream from a cursor, like every other collection:

- PlaylistTrackRepository gains GetCursor and CountAll, sharing the select
  builder with loadTracks so cursor rows hydrate identically, plus
  GetMediaFileIDs for callers that need every id but no track data.
- playlists.Tracks(ctx, id) exposes that repo to the HTTP layer with visibility
  enforced, returning ErrNotFound rather than the repo's nil-and-log-a-warning
  (which /Items would hit on every album browse, since ParentId is usually not
  a playlist).
- /Playlists/{id}/Items now honors StartIndex/Limit, which it silently ignored
  before — it always returned the whole playlist. Real Jellyfin pages it.
- getPlaylist runs an id-only query: PlaylistInfo carries every track id so it
  can't be paged, but it no longer hydrates rows it discards.
- The route joins the throttled group, as it's now cursor-backed.

Measured against a copy of a 96k-track production DB, peak RSS over idle, with
byte-for-byte identical responses on every endpoint:

  /Items?ParentId=<pl>&Limit=10   1275MB -> 1MB    8.8s -> 3.6s (0.27s warm)
  /Items?ParentId=<pl> unbounded  1353MB -> 8MB    8.7s -> 3.4s
  /Playlists/<pl>/Items           1217MB -> 7MB    8.8s -> 3.4s
  /Playlists/<pl>                 1178MB -> 33MB   9.1s -> 3.8s

TotalRecordCount now costs a count query where the old path got it from
len(tracks): 6ms on the largest real playlist in that library (2638 tracks),
288ms on the synthetic all-96k one. The old path paid 1.3GB and 4s+ instead.

* fix(jellyfin): bound unbounded /Items searches

The other collections stream, so an unbounded one costs about one item of
memory. Search can't: the repositories' Search returns a slice, so it
materializes every match. PR #5783 left two ways to reach that.

A whitespace-only SearchTerm was the first. " " != "", so it took the search
path, where doSearch trims it back to empty and hits its "empty query, return
everything in natural order" branch — with no LIMIT, since executeTwoPhase only
applies one when Max > 0. The whole library, materialized. Trimming at the two
parse sites makes the `search != ""` checks mean what they look like they mean:
a blank term is not a search, so it takes the unfiltered streaming path, which
still returns everything, exactly as real Jellyfin does for an empty term.

A real search with no Limit was the second, and needs an actual bound. Search
gets a default of 100 when the client sends no Limit — matching the
DefaultSearchLimit in Jellyfin's unreleased SqlSearchProvider — plus a ceiling,
without which Limit=999999 would still materialize the library. The default
alone wouldn't have closed the hole. An explicit Limit under the ceiling is
honored unclamped, as upstream does; truncating a search is safe in a way
truncating /Items is not, since nothing syncs a library through searchTerm.

Note this is upstream's own bug: v10.11's /Search/Hints returns the entire
library for a whitespace-only term, which master fixed by switching to
ThrowIfNullOrWhiteSpace.

* fix(jellyfin): cap the search Limit the client asked for, not the merge window

searchPage sees two different things in opts.Max: the client's Limit for a
single-type query, and mergeTypes' internal offset+limit window for a multi-type
one. Clamping there hit both, so a multi-type search paging past the ceiling
fetched only `ceiling` rows of the first type and the merged page skipped into
the next one — IncludeItemTypes=Audio,MusicAlbum&SearchTerm=song&StartIndex=2000
&Limit=1 returned an album instead of the 2001st song.

The ceiling now applies where the client's Limit is read: queryItems (after the
playlist branch, so a playlist parent's page isn't capped by a stray SearchTerm)
and getArtists, which reads its own. A limit of 0 stays 0, keeping searchPage's
default. What a deep page materializes is then bounded by the client's
StartIndex, as it already was for any multi-type query, search or not.

Also from review: the playlist-track mock reused the previously stored Options
when called without any, so a later no-args call inherited stale paging.

* fix(jellyfin): apply the search default to the client's Limit, not per type

The default lived in searchPage, which runs per type and after mergeTypes has
already picked its branch. So an unbounded multi-type search left q.limit at 0,
mergeTypes took its chained branch, and StartIndex was applied to a list each
type had already truncated to the default — dropping matches rather than paging
them. With 200 matching songs, IncludeItemTypes=Audio,MusicAlbum&SearchTerm=song
&StartIndex=150 returned nothing at all, and without StartIndex it returned the
default per type instead of in total.

clampSearchLimit now applies the default and the ceiling together, to the
client's Limit, at the two places it's read (queryItems and getArtists). A search
therefore always gives mergeTypes a real window, so it pages the merged result
and cuts it once, at the end.

* fix(jellyfin): bound the multi-type search window against StartIndex

mergeTypes asks each type for offset+limit rows before paginating the merged
list, so a search still materialized whatever StartIndex asked for:
IncludeItemTypes=Audio,MusicAlbum&SearchTerm=x&StartIndex=500000&Limit=1 pulled
~500001 matches per type. Bounding the window alone isn't enough — below it the
merged rows are the client's page, but at it a truncated type is followed by the
next one's rows, which is what made a clamped window serve an album where the
2001st song belonged.

So the window is capped at maxSearchLimit and the page is clipped to it: pages
below the ceiling are served in full and unchanged, a page straddling it is cut
at it, and past it the result is empty rather than another type's rows. The
total reports what can actually be paged to, so a client stops instead of asking
for pages that no longer exist.

This is the merge's own limit, not the client's: a single-type search still pages
as deep as it likes, since its offset goes to SQL. Non-search multi-type queries
keep the unbounded offset+limit window, which predates this and wants the same
treatment via CountAll (exact per-type totals let whole types be skipped) rather
than a cap.

* fix(jellyfin): advertise the pageable search total, not the page window

Clipping the multi-type search total to `window` clipped it to StartIndex+Limit
on an ordinary page, so a first page of Limit=10 reported TotalRecordCount 10
however many matches there were, and a client paging on the total stopped after
one page. The cap belongs at the ceiling — what can be paged to overall — not at
the current page.

The tests missed it because the only one asserting a total used
StartIndex=maxSearchLimit, where the window happens to equal the ceiling.

* refactor(jellyfin): fold the search clamp into clampLimit and simplify mergeTypes

Cleanup pass over the branch, no behaviour change:

- clampSearchLimit was clampLimit (similar.go) with different constants, so the
  latter takes the default and ceiling as arguments and both call it. Similar's
  default moves out of three IntOr calls into defaultSimilarLimit.
- mergeTypes derived a second `limit` and needed an early return for the empty
  page, only because paginate reads 0 as "unbounded". Clipping the merged slice
  to the window instead lets q.limit be passed straight through: window is
  min(offset+limit, ceiling), so clipping there is the same cut.
- playlistTracks returned (result, handled, error) where handled=false always
  meant error=nil. Splitting the lookup out gives playlistTracksRepo returning
  (repo, ok), and the nilerr suppression goes with it.
- The comment on playlists.Tracks blamed the log warning for its extra Get; the
  reason is that PlaylistRepository.Tracks discards the error behind a nil. Also
  drops a stale reference to a renamed variable.

fix(jellyfin): stream collection responses to prevent OOM on large libraries (#5783)
* fix(jellyfin): stream /Items responses to prevent OOM on large libraries

Finamp's library sync issues an unbounded GET /Items?IncludeItemTypes=Audio
with Fields=MediaSources and no Limit. On a large library this built the whole
result set — every MediaFile and every BaseItemDto, each fat with MediaSources —
in memory, and json.Encoder then buffered the entire ~200MB response before
writing a byte. Measured on a 96k-track library, one such request peaked near
1.6GB RSS; in a memory-limited container the resulting slowness made clients
retry, stacking concurrent full-library builds until the process was OOM-killed.

Stream the song listing straight from a DB cursor (MediaFileRepository.GetCursor),
mapping and encoding one row at a time, so peak memory is bounded to about one
item regardless of library size. The cursor is opened lazily, when streaming
begins, so it doesn't hold a DB connection across the CountAll and ServerId
lookups that run first (ServerId can write on first use and would deadlock
against an open reader). Pagination still works — the cursor query carries
LIMIT/OFFSET/ORDER BY from StartIndex/Limit/SortBy — and TotalRecordCount stays
the full count. Other materialized responses stream their JSON too, avoiding the
encoder's buffer-the-whole-output cost.

Also bound artwork image concurrency with the same server.ThrottleBacklog that
Subsonic's getCoverArt uses, so a burst of image requests during sync can't
exhaust memory through concurrent decode/resize.

Verified against a copy of a 96k-track production database: byte-for-byte
identical response, peak RSS 1593MB -> 53MB, time-to-first-byte 8.1s -> 0.2s.

* fix(jellyfin): fail loudly on /Items streaming errors instead of a truncated 200

Addresses code review: a streamed /Items response commits HTTP 200 before an
error can occur, so failures were surfacing as misleadingly successful bodies.

- A cursor-open failure (e.g. a busy DB under connection pressure) is now
  surfaced before the first byte is written: the cursor open is deferred into
  the item source and run in writeItems after the ServerId lookup but before the
  envelope, returning a clean 500 the client can retry — not a 200 with an empty
  item list.
- A mid-stream (row-scan) error now aborts without closing the JSON envelope,
  leaving the body malformed. A truncated-but-valid response would let a sync
  client (Finamp) treat the short list as the whole library and prune local
  tracks; malformed JSON forces the client's parser to fail and retry.

* refactor(jellyfin): stream every collection endpoint from a DB cursor

Streaming was applied only to the song listing, which left two write paths, two
ServerId stamping mechanisms and a listXxx return-type split ("songs is
special") that made the code hard to follow.

Add GetCursor to the album, artist, genre and playlist repositories, mirroring
MediaFileRepository.GetCursor: same select builder as GetAll, so each cursor
yields identical, fully-hydrated rows (hydration happens per-row in PostScan,
and toModels is only a deref loop). The playlist cursor keeps GetAll's
owner/public visibility filter. Each repository test asserts the cursor yields
exactly what GetAll returns, including Max/Offset.

With cursors everywhere, every listXxx returns itemsResult and every collection
streams through one writer:

- listAlbums, listArtists and listPlaylists now stream from their cursors;
  search paths stay materialized (Search returns a slice).
- listGenres stays materialized: its total is the length of the full list and it
  paginates in memory, so there is nothing for a cursor to page over.
- api.ok's QueryResult case delegates to writeItems, so the ~9 inline callers
  funnel into the same writer; streamQueryResult and wrapResult are gone.
- /Items/Latest streams as a bare JSON array (its Jellyfin wire shape) via
  writeItemsArray, which shares the item loop and stamping. That also closes the
  same unbounded hole /Items had: limit=0 disabled its LIMIT.
- ServerId is now stamped in exactly one place, so api.ok only handles single,
  non-collection payloads.

Verified against a copy of a 96k-track production database: every endpoint
byte-for-byte identical to master. Unbounded /Items peak RSS 1691MB -> 54MB;
time-to-first-byte 6.3s -> 0.19s, /Artists 1.14s -> 0.13s.

* refactor(jellyfin): route every response through api.ok

Handlers were split between api.ok and api.writeItems with no clear rule for
which to call. api.ok now accepts itemsResult too, so it is the single entry
point: callers hand it whatever they have and it routes collections (cursor
-backed or materialized) to the streaming writer. writeItems is reached only
through api.ok now. The one exception is /Items/Latest, which returns a bare
JSON array rather than a QueryResult envelope and so writes directly — noted in
both doc comments.

Also drop GenreRepository.GetCursor: listGenres derives its total from the
length of the full list and paginates in memory, so there is nothing for a
cursor to page over, leaving the method unused.

* fix(jellyfin): stream the unbounded multi-type /Items merge

The multi-type merge capped each per-type query at offset+limit only when a
Limit was given. Without one (Finamp's favorites screen sends multi-type), every
type ran an unbounded query and collect() drained each cursor into a slice — so
/Items?IncludeItemTypes=MusicAlbum,Audio with no Limit materialized every album
and every song, the same OOM class this branch set out to fix. The comment
claiming the set was "capped at offset+limit per type" was wrong for limit=0.

Without a limit the merged page is just each type's rows in order minus the
first offset, which is exactly what chaining the per-type cursors yields, so
stream that instead of merging in memory. The bounded path is unchanged: with a
Limit each type holds at most offset+limit rows, so merging and paginating
across the combined list is safe. Cursors are opened one at a time (each pins a
DB connection until drained), with the first opened eagerly so the usual failure
is still a clean error before any byte is written.

Measured on a 96k-track library, /Items?IncludeItemTypes=MusicAlbum,Audio with
no Limit (103,393 items): peak RSS 612MB -> 53MB, time-to-first-byte 4.9s ->
0.6s, response byte-for-byte identical.

* refactor(jellyfin): parse /Items params into a struct

The /Items dispatcher was a single 90-line block that parsed a dozen params and
then threaded them positionally through three layers — queryItemsOfType took 11
arguments, listSongs and listAlbums 9 each — so reading any one of them meant
decoding a long argument list.

Parse once into an itemsQuery and pass that instead. queryItems now reads as the
four things it actually does: parse, the id/playlists-folder/playlist-parent
special cases, single-type dispatch, multi-type merge — with the playlist-parent
and merge bodies moved to playlistTracks and mergeTypes. Every listXxx takes
(ctx, opts, q).

No behavior change: parsing, ordering and the entityParent rule are unchanged,
and /Artists still passes favOnly=false explicitly by building the subset of the
query it uses.

* docs(jellyfin): trim comments on the streaming path

Cut the comments back to the non-obvious why: the deferred cursor open (the
ServerId write would deadlock against an open reader), the deliberate malformed
JSON on a mid-stream error, why chained opens one cursor at a time, why
listGenres stays materialized, and why the cursor helpers take the underlying
func type. Dropped the rest — restatements of the code, doc comments that
repeated a test's own name, and the GetCursor interface comments that the
existing MediaFileRepository.GetCursor does without.

* refactor(persistence): fold the cursor wrappers into a generic wrapCursor

wrapAlbumCursor, wrapArtistCursor, wrapMediaFileCursor and wrapFolderCursor were
the same twelve lines four times over, differing only in the type name, and the
playlist cursor had its own inline copy of the loop.

Add one generic wrapCursor. It takes an extractor func rather than a method on
an interface: a type parameter can't reach an embedded field, and methods that
only satisfy a generic constraint are reported by the unused linter. The
extractor also lets both type parameters be inferred, so call sites need no
explicit instantiation. Each entity keeps its named wrapper as a one-liner,
since the model cursor types are defined types and need the conversion — and the
existing wrapper tests call them directly.

The nil-row error now names the model type via %T ("unexpected nil model.Album")
instead of a hand-written per-entity string; the three tests asserting that
message are updated.

* fix(jellyfin): bound concurrent collection streams

A streamed collection holds a DB cursor — and its pooled connection — for the whole client-paced
response, where the old materialize-then-write path released it as soon as the query finished. The
pool is shared with the scanner, Subsonic, the native API and the UI, so enough slow clients take
every connection and everything else blocks waiting for one. Measured against a copy of a 96k-track
production DB, 20 concurrent unbounded streams against a pool of 16 stalled a write for 16.2s (the
other 14 writes in the run took ~2ms — the signature of connection starvation, not lock contention).

Cap concurrent streams at half the pool. Excess requests queue rather than fail, so no client is
rejected: the same 20 streams now all complete and the worst write is 2.5ms.

- conf.MaxOpenConns() now owns the pool sizing (db calls it). It belongs in conf: the pool is a
  tunable, db already imports conf, and putting it in db would force server/jellyfin to import db
  just to size the cap against it. Expressing the cap as MaxOpenConns()/2 also keeps the two from
  drifting apart.
- Uses chi's ThrottleBacklog, not server.ThrottleBacklog: the latter buffers the whole response to
  release its token early, which is right for artwork but would undo the streaming. chi's panics on a
  non-positive limit, so throttleStreams guards it — setting MaxConcurrentStreams=0 disables the cap
  instead of crashing the server at startup.

* refactor(jellyfin): move throttleStreams to middlewares.go

It's a middleware, so it belongs beside normalizeQueryKeys, authenticate and
withPlayer rather than in api.go. Its tests move to middlewares_test.go with it,
keeping one test file per production file.

* fix(jellyfin): abandon the scan when the client stops reading

encodeItems discarded its write errors and relied on the final Flush to report
them, so once bufio's buffer filled and the flush failed, the loop still pulled
every remaining row through the cursor and serialized it for a client that was
gone. A test with a failing writer confirms it: all 20k items were drained.

That wastes CPU, and holds the cursor's pooled DB connection and a stream slot
(now a capped resource) for the length of a full scan nobody is reading. Check
the per-item writes so the first failure ends the scan; the fixed envelope
writes stay unchecked, since bufio latches for them anyway.

feat(jellyfin): experimental Jellyfin Music API support (#5730)
* feat(sharing): enable sharing by default

Flip the EnableSharing default from false to true so new installations have the sharing feature available out of the box. Users can still disable it via the EnableSharing config option.

The native API only registers the /share route when sharing is enabled, so the nativeapi tests that build the router without wiring a share service now explicitly disable sharing in their setup to avoid registering a route backed by a nil service.

* feat(jellyfin): add config flag and URL path constant

Adds the disabled-by-default Server.Jellyfin config option (Enabled,
ServerName) and consts.URLPathJellyfinAPI, following the existing
LastFM/ListenBrainz patterns. Later tasks will use these to mount the
Jellyfin-compatible API router.

* fix(jellyfin): default Jellyfin ServerName to "Navidrome"

* feat(jellyfin): package skeleton with System handshake endpoints

Adds server/jellyfin: the Router (mirrors server/subsonic and
server/public), its Wire-friendly New(...) constructor, a chi routes()
table, and the ok() JSON response helper. Implements the unauthenticated
handshake surface Jellyfin clients probe first: GET /System/Info/Public,
GET+POST /System/Ping, and GET /QuickConnect/Enabled (quick connect is
unsupported, so it always reports disabled).

The public info payload's Id must be stable across restarts (Jellyfin
clients cache ServerId), so it reuses the get-or-create Property pattern
already used for InsightsID in core/metrics/insights.go: fetch
consts.JellyfinServerIDKey from the Property repository, generating and
persisting a new UUID on first read. A dedicated key (rather than the
existing InsightsID) keeps the anonymous telemetry identifier from being
exposed on this unauthenticated endpoint.

* test(jellyfin): cover ping and quickConnectEnabled handlers

Both were added alongside the System/Info/Public handshake endpoint but
had no direct test coverage.

* fix(jellyfin): memoize stable server Id and cover get-or-create path

* feat(jellyfin): wire and mount the router behind Jellyfin.Enabled

Add jellyfin.New to the shared Wire provider set and a
CreateJellyfinAPIRouter injector, then mount the router at /jellyfin
in startServer(), gated by conf.Server.Jellyfin.Enabled, mirroring the
existing LastFM/ListenBrainz router mounts.

* feat(jellyfin): add Jellyfin DTOs and model mappers

Adds BaseItemDto, QueryResult, UserItemDataDto, UserDto,
AuthenticationResult, MediaSourceInfo, PlaybackInfoResponse,
NameGuidPair and SessionInfo DTOs to server/jellyfin/dto, plus
model-to-DTO mappers for songs, albums, artists and genres that
later browse/stream/write endpoints will consume.

* test(jellyfin): cover GenreToBaseItem mapper

* feat(jellyfin): advertise Jellyfin-compatible version, brand ServerName with Navidrome version

* fix(jellyfin): map LastPlayedDate and omit zero track/disc numbers

* feat(jellyfin): authentication middleware and AuthenticateByName login

* fix(jellyfin): reject empty login password, wire ServerName, add negative auth tests

* refactor(jellyfin): use new(x) builtin instead of intPtr helper

* feat(jellyfin): user views and current-user endpoints

* feat(jellyfin): Items query engine, item detail, and latest

Adds the /Items universal query endpoint, dispatching by IncludeItemTypes
over albums/artists/songs/genres with ParentId, SearchTerm, Filters=IsFavorite,
SortBy/SortOrder and StartIndex/Limit support, plus GET /Items/{itemId} and
/Users/{userId}/Items/Latest. Reuses server/subsonic/filter builders (by
artist/album/starred) instead of hand-rolled squirrel filters, and resolves
sort keys per item type since each repository maps sort names to different
real/aliased columns.

Also adds the missing CountAll to tests.MockArtistRepo, exposed by this task
(the mock embedded a nil ArtistRepository for it and would panic on use).

* refactor(server): extract shared query filter builders to server/filter

Moves server/subsonic/filter to server/filter so server/jellyfin can use
the shared query-option builders without importing server/subsonic,
enforcing the rule that no API package imports another API's package.

* feat(jellyfin): full multi-library support with per-user access scoping

Replace the single hardcoded "music" UserView with one CollectionFolder
view per library the user can access, and scope every /Items browse
query (albums, songs, artists, /Latest) to those libraries via
server/filter's ApplyLibraryFilter/ApplyArtistLibraryFilter.

ParentId is now disambiguated: a numeric value the user has access to is
treated as a library scope (browsing a UserView), otherwise it falls
through as an entity id (artist/album), which safely matches nothing
rather than leaking another library's content. getItem now 404s when
fetching an album or song outside the user's accessible libraries;
artists are skipped (they can span multiple libraries) with a TODO.

Genres remain unscoped since they're global tags, not per-library
entities.

* test(jellyfin): cover admin library-access path and drop nil test contexts

* feat(jellyfin): Artists and Genres endpoints

Add /Artists, /Artists/AlbumArtists, /Genres and /MusicGenres. Artists
listing is library-scoped (defaulting to the user's accessible
libraries, narrowed by an accessible ParentId), delegating access
control to listArtists/ApplyArtistLibraryFilter. Genres are global and
unscoped, matching the ML decision already made for listGenres.

* refactor(jellyfin): share resolveLibraryScope between items and artists

* feat(jellyfin): item image endpoint via artwork service

* fix(jellyfin): let net/http sniff image Content-Type instead of forcing jpeg

* feat(jellyfin): audio streaming and PlaybackInfo with library access control

* feat(jellyfin): favorites and rating write-back with library access control

Adds POST/DELETE handlers for /Users/{userId}/FavoriteItems/{itemId} and
/Users/{userId}/Items/{itemId}/Rating. A shared resolveAnnotated helper
probes album/artist/media file (mirroring getItem's order) and 404s before
writing if the user lacks access to the album/song's library; artists are
exempt since they span multiple libraries. Ratings are halved coming in
(Jellyfin 0-10 -> Navidrome 0-5) to match the doubling in dto.UserData.

Also teaches MockMediaFileRepo and MockArtistRepo's SetStar/SetRating (and
MockAlbumRepo's, previously a no-op) to actually mutate the backing data so
write-back can be asserted in tests.

* feat(jellyfin): playback reporting and scrobbling

Add /Sessions/Playing[/Progress|/Stopped] and /Sessions/Capabilities[/Full]
handlers, backed by core/scrobbler.PlayTracker. A new withPlayer middleware
resolves/registers a model.Player from the Emby DeviceId header (used
directly as the stable player id, unlike Subsonic's cookie fallback) and
injects it into the request context for scrobbling.

The Stopped report calls ReportPlayback with IgnoreScrobble to end the
now-playing session without double-counting, then calls Submit as the
single source of the play-count increment and external scrobble.

* feat(jellyfin): playlist read and write-back

Adds POST /Playlists, GET/POST/DELETE /Playlists/{id}/Items. Tags each
playlist item with PlaylistItemId (the entry's position within the
playlist) so DELETE .../Items?EntryIds=... can remove a specific
occurrence by the id core/playlists.RemoveTracks actually expects,
rather than the song id used everywhere else.

* test(jellyfin): cover empty Ids/EntryIds in playlist add/remove

* feat(jellyfin): unknown-route logging, generic 500s, rating clamp, docs

Hardening pass ahead of real client testing: unmatched routes and
unsupported methods now return a logged, JSON 404 instead of chi's
default plain-text response, so a missing endpoint a client needs is
easy to spot in the logs. Internal errors (ffmpeg output, file paths,
etc.) no longer leak into 500 response bodies -- a shared
internalError helper logs the real error server-side and always
returns a generic message. Inbound Jellyfin ratings are clamped to
0-10 before being halved into Navidrome's 0-5 scale, and /System/Ping
now replies with a bare plain-text body as real Jellyfin servers do.
Adds a README with an enable/curl walkthrough and known limitations.

* docs(jellyfin): clarify public image endpoint and accessibleLibraryIDs comments

* fix(jellyfin): case-insensitive path routing for Jellyfin client compatibility

* refactor(server): extract case-insensitive path routing to a shared helper

* fix(jellyfin): return User Policy and Configuration so Finamp completes login

* fix(jellyfin): support Playlist type, multi-type Items queries, and PlayCount/DatePlayed sort

Real Finamp requests break against three /Items query engine bugs: Playlist
requests fell through to albums, multi-type IncludeItemTypes (e.g. Finamp's
favorites screen) only returned the first requested type, and comma-separated
SortBy lists (e.g. "DateCreated,SortName") were matched as one opaque string
so they always fell through to the repo default.

Also extends tests/mock_playlist_repo.go with SetData/GetAll so playlist
listing is testable like the other mock repos.

* feat(jellyfin): implement /socket WebSocket for real-time client sessions

* fix(jellyfin): resolve library-view ids in getItem so clients can load the library

* fix(jellyfin): serve direct file at /Items/{id}/File and accept ApiKey query param

* fix(jellyfin): resolve playlist ids in getItem

* fix(jellyfin): read lowercase ids/entryIds playlist params and add playlist-users endpoints

* fix(jellyfin): include MediaSources with Size/Bitrate on tracks so clients show download size

* fix(jellyfin): populate all required MediaSourceInfo bool/array fields to match Jellyfin

* fix(jellyfin): hex-encode item ids at the API boundary for Jellyfin client compatibility

Finamp (and presumably other clients) parses ids as radix-16, but Navidrome's
base62 nanoids aren't valid hex and crash its queue packing. Hex-encode every
id emitted by the Jellyfin API and decode every id received, keeping the
transform reversible and stateless at the boundary rather than touching any
model id.

* fix(jellyfin): populate MediaStreams with the audio stream so clients can size/transcode

* fix(jellyfin): support Ids batch-fetch in /Items so clients can fetch items by id

* fix(jellyfin): do not disable Jellyfin server when disabling external services

* fix(jellyfin): emit per-image ImageBlurHashes so clients de-dupe images and stop warning

* fix(jellyfin): support playlist cover upload/delete and display via item image endpoints

* feat(jellyfin): implement GET /Playlists/{id} for playlist visibility

Finamp's playlist edit screen calls GET /Playlists/{id} to read the
OpenAccess (public visibility) flag; we only had the sub-routes, so it
404'd and the edit screen failed to load. Return the Jellyfin PlaylistDto
shape (OpenAccess from Public, empty Shares, media item ids).

* fix(jellyfin): display playlist cover art

Uploaded playlist covers never showed in clients for two reasons: the
playlist BaseItemDto advertised no Primary ImageTag (so clients didn't
know to fetch a cover), and the public image endpoint resolved artwork
under the request's anonymous context, so a private playlist failed its
visibility filter and fell back to the placeholder. Advertise the Primary
image tag/blurhash on playlists, and resolve artwork under an elevated
context (as core/artwork's cache warmer does).

* fix(jellyfin): expand album/artist/playlist ids when building playlists

Jellyfin clients (Finamp) send container ids — an album, artist or
playlist — in a playlist's Ids list and expect the server to expand each
into its child tracks. core/playlists only understands media file ids, so
creating or adding with an album id silently produced an empty playlist.
Expand container ids to their tracks (in order) before create/add; bare
song ids still pass through. Adds filter.SongsByArtistID.

* fix(jellyfin): support playlist deletion via DELETE /Items/{id}

Finamp deletes a playlist with DELETE /Items/{id}, which we didn't route,
so deletion silently failed. Implement it via core/playlists.Delete (which
enforces ownership and removes the cover file). Only playlists are
deletable through this API; non-playlist ids return 404, non-owners 403.

* test(jellyfin): add e2e suite harness + smoke tests

* test(jellyfin): e2e for system, auth, routing, browsing, annotations

* test(jellyfin): e2e for playlists (CRUD, expansion, cover) and item images

* test(jellyfin): e2e for streaming, sessions, and multi-user access control

* fix(jellyfin): artist search 500 (library filter leaked into FTS query)

getArtists/listArtists reused the browse-path filters (notMissing +
ApplyArtistLibraryFilter) for the search path, but artist Search expects a
sole Eq{library_id} filter it can consume as a scope — artists have no
library_id column, so the compound/join filter leaked into the FTS query
and 500'd. Every Finamp artist search failed (the filter is applied even
unscoped, since admins resolve to all library ids). Build search filters
separately. Adds e2e search coverage.

* feat(jellyfin): implement POST /Playlists/{id} to update name, visibility, tracks

Finamp edits a playlist (make public, rename, reorder) via POST
/Playlists/{id}, which we didn't route, so every edit 404'd. Implement it:
Ids present -> replace track list (Create with existing id, preserving
name); otherwise update Name/IsPublic via core/playlists.Update. Adds a
shared playlistError helper (403/404/500) reused by deleteItem, plus e2e
coverage.

* docs(jellyfin): update README for playlists, images, id encoding, and e2e

* fix(jellyfin): default album track listing to track order

Browsing an album's tracks (Items?ParentId=<albumId>&IncludeItemTypes=Audio)
took only SongsByAlbum's filters and dropped its Sort, so tracks came back
in arbitrary order. Default opts.Sort to the album (disc+track) order when
browsing an album without an explicit SortBy — matching Subsonic's GetAlbum
and real Jellyfin. An explicit SortBy still wins.

* fix(jellyfin): filter items by AlbumArtistIds/ArtistIds

An artist's page in Finamp sends ParentId=<libraryId> (scoping) plus
AlbumArtistIds/ArtistIds/contributingArtistIds for the artist itself, but
queryItems only honored ParentId, so an artist's albums and tracks came
back unfiltered (every artist's content). Parse the artist-id params and
apply AlbumsByArtistID (albums) / SongsByArtistID (tracks). Adds e2e
coverage.

* fix(jellyfin): only count a play past the scrobble threshold

reportPlaybackStopped set IgnoreScrobble and force-submitted a play on
every Stopped report, so a briefly-played track (e.g. an immediate skip)
was marked played. Finamp sends Stopped on every track switch, so the
threshold must be applied server-side. Let ReportPlayback's StateStopped
logic decide (play + scrobble only past 50% of the track / 4-minute cap)
instead. Subsonic differs because there the client gates submission.

* fix(jellyfin): sort album tracks by track number when client sends IndexNumber SortBy

Finamp's album view requests SortBy=ParentIndexNumber,IndexNumber,SortName
(disc, track, name), but applySort didn't recognize ParentIndexNumber or
IndexNumber and fell through to SortName, sorting tracks alphabetically by
title. Map both keys to the album (disc+track) sort. The reversed-title
fixture lets the e2e tell track order from title order.

* fix(jellyfin): honor the isFavorite query param for favorites filtering

Finamp's artist 'Favourite tracks' widget requests favorites via the
standalone isFavorite=true query param, not Filters=IsFavorite, so the
filter was ignored and non-favorited tracks were returned. Detect both
forms. (The widget's reshuffling is Finamp's explicit SortBy=Random.)

* feat(jellyfin): emit DateCreated (Date Added) on items

BaseItemDto had no DateCreated, so clients showed 'No Date Added' and had
nothing to sort 'Recently Added' by. Emit it as ISO 8601 from each entity's
CreatedAt (the same field the recently_added sort uses) for songs, albums
and artists.

* fix(jellyfin): set ArtistItems/AlbumArtists on songs (Now Playing artist)

SongToBaseItem only set Artists (names) and AlbumArtist, not the structured
ArtistItems/AlbumArtists. Finamp's Now Playing screen reads ArtistItems and
shows 'Unknown Artist' when it's absent. Populate both (track artist and
album artist) as name+id pairs, mirroring AlbumToBaseItem.

* docs(jellyfin): note synthetic blurhash as a follow-up

Document that ImageBlurHashes are derived from the item id (a solid-color
placeholder), not computed from the cover art like real Jellyfin, and
outline what a proper implementation would take.

* docs(jellyfin): note WebSocket events and favourited playlists as follow-ups

* fix(jellyfin): filter the Artists page by role (album artist vs performer)

/Artists and /Artists/AlbumArtists both called the same role-agnostic
handler, so Navidrome's per-role artist entries (composers, arrangers,
performers) all showed as Album Artists, and the two tabs were identical.
Filter /Artists/AlbumArtists to RoleAlbumArtist and /Artists to RoleArtist
(and the MusicArtist browse to album artists), via filter.ArtistsByRole.
Verified live: Beatles Singles' album-artists dropped 138->5, composers
excluded, performers (Billy Preston) show only under /Artists.

* fix(jellyfin): sort playlists by name (missing Playlist sort mapping)

applySort had no sortColumnsByType entry for the Playlist type, so
SortBy=SortName was ignored and the Playlists screen showed them in the
repo's default order. Map SortName/Name -> name (as Subsonic does) and
DateCreated -> created_at. Verified live: case-insensitive alphabetical.

* fix(jellyfin): read query params case-insensitively (Jellify support)

Jellify (and the official Jellyfin TypeScript SDK) send query params in
camelCase (parentId, albumArtistIds, artistIds, includeItemTypes), where
Finamp sends PascalCase. Our handlers read fixed-case keys, so every
Jellify filter/sort/paging param was silently dropped:

- an artist's page listed albums and tracks from all artists
- opening an album listed every album instead of its tracks

Real Jellyfin binds query params case-insensitively (ASP.NET model
binding), so add a normalizeQueryKeys middleware that folds every query
key to lowercase once, and read params by their lowercase name. This
also removes the scattered dual-case hacks (Ids/ids, IsFavorite,
ContributingArtistIds, api_key/ApiKey, queryParam) that let this bug
class through.

Also infer the child type from an album parent: Jellify browses an album
with only parentId (no IncludeItemTypes), and Jellyfin infers Audio from
the parent; without it we fell back to listing all albums.

Verified live against Finamp+Jellify and with 4 new e2e specs replaying
Jellify's exact request shapes.

* fix(jellyfin): advertise LocalAddress in the public system info handshake

Jellify (and other @jellyfin/sdk clients) that connect by raw address fall
back to HTTP when TLS isn't available, then adopt the handshake's
LocalAddress as their server base URL. We never populated it, so Jellify's
SDK `api` object was undefined and sign-in crashed with "Cannot read
property 'configuration' of undefined" (getUserApi(api!) with an undefined
api). Over an HTTPS connection Jellify uses connectionType=hostname and
never reads LocalAddress, which is why it worked while an HTTPS proxy was
in front.

Populate LocalAddress from the request — scheme + host (honoring
X-Forwarded-*), plus the /jellyfin mount path — matching real Jellyfin,
which always sends it. Export server.ServerAddress for the resolution.

* fix(jellyfin): separate "Featured On" from an artist's own discography

Jellify's artist page fetches the discography via albumArtistIds and the
"Featured On" section via contributingArtistIds, relying on the server to
return disjoint sets. We collapsed albumArtistIds/artistIds/
contributingArtistIds into one AlbumsByArtistID filter, so an artist's own
albums appeared in both sections.

Add AlbumsByContributingArtistID — albums where the artist is a track
artist but NOT the album artist — matching Jellyfin's ContributingArtistIds
(in Artists, not in AlbumArtists), and route contributingArtistIds to it.

* fix(jellyfin): accept a bare Authorization token for audio streaming

Jellify's native player (react-native-nitro-player) authenticates the audio
stream by setting a bare Authorization header carrying the raw access token
({ AUTHORIZATION: api.accessToken }), not the "MediaBrowser ... Token=" scheme
parseEmbyAuth understands. tokenFromRequest didn't recognize it, so every
/Audio/{id}/stream request from the native player 401'd and no audio played
(the JS client still optimistically posted playback progress, masking it).

Accept a bare (or "Bearer <token>") Authorization header, as real Jellyfin
does. Verified live: the native player's exact request now streams 200.

* fix(jellyfin): embed a self-authenticating stream URL in PlaybackInfo

Jellify's native audio player (react-native-nitro-player / ExoPlayer) fetches
the stream without forwarding any auth — captured request headers were only
Connection/Icy-Metadata/Accept-Encoding/User-Agent, no Authorization and no
api_key — so every /Audio/{id}/stream request 401'd and nothing played (the
JS client still optimistically posted progress, masking it).

Real Jellyfin returns stream URLs with the token embedded; we returned none,
so Jellify fell back to a token-less DirectPlay URL. Populate
MediaSources[0].TranscodingUrl with /Audio/{id}/universal?api_key=<caller
token>, which Jellify's player uses verbatim. Direct-play clients (Finamp
builds its own /Items/{id}/File?ApiKey URL) ignore the field, so they're
unaffected.

* feat(jellyfin): serve per-item UserData (GET /UserItems/{id}/UserData)

Jellify fetches this per item to render played/favourite indicators; we 404'd
it. Resolve the item via the existing getItem resolver (which loads the
caller's annotations and enforces the same library-access gate) and return its
UserData, falling back to an empty-but-valid object for items without
annotations (e.g. playlists). Also registers the legacy
/Users/{userId}/Items/{itemId}/UserData spelling.

* refactor(jellyfin): drop unused bare-Authorization token support

Added mid-troubleshooting on the theory that Jellify's native player sends a
bare Authorization header, but the debug capture showed it sends no auth header
at all — the real fix was embedding api_key in PlaybackInfo's TranscodingUrl.
No client reaches this path (Jellify JS uses the MediaBrowser scheme, Finamp
uses X-Emby-Token, the native player uses the api_key URL), so remove it and
its tests per YAGNI. Effectively reverts 4f8ac1e0.

* feat(jellyfin): implement Similar endpoints via the external provider

Add GET /Artists/{id}/Similar (related artists) and GET /Items/{id}/Similar
(similar songs for a track, similar albums for an album, related artists for an
artist), sourced from the same external.Provider (Last.fm etc.) that powers
Subsonic's getArtistInfo2/getSimilarSongs. Only library-present artists are
returned so each is navigable; provider errors and unknown ids degrade to an
empty 200 result, so clients (Jellify) stop hammering these with 404 retries.

Injects external.Provider into the Router (regenerated via make wire).

* perf(jellyfin): make Similar endpoints non-blocking (bounded quick wait)

Each /Similar request fetched from Last.fm synchronously (500ms-1.4s), and
Jellify requests Similar for many items at once on the home/artist screens, so
the whole screen stalled — a home pull-to-refresh dragged for seconds.

Run the external lookup on a background context and return within a 500ms quick
wait: a cached artist resolves instantly, a cold one returns empty now while the
lookup finishes caching in the background, so a later load is fast and
populated. Verified live: cold calls bounded at ~500ms (was up to 1.4s), warm
calls 3-8ms.

* fix(jellyfin): answer ManualPlaylistsFolder so the home stops stalling

Jellify resolves its "playlists library" via IncludeItemTypes=
ManualPlaylistsFolder, then lists playlists with ParentId set to that folder's
id. We didn't recognize the type, so parseTypes fell back to MusicAlbum and
returned the album list. Jellify's query then found no item with
CollectionType=playlists and resolved undefined — which React Query rejects,
retrying it in a backoff loop that stalled the home pull-to-refresh for ~5s
(every response was fast server-side; the delay was the client's retries).

Return a synthetic "playlists" folder (CollectionType=playlists) for the
ManualPlaylistsFolder query, resolve ParentId=<that folder> to the user's
playlists, and give playlists a Path under "data" (Jellify drops playlists
whose Path lacks it). Adds a Path field to BaseItemDto.

* docs(jellyfin): note lyrics and InstantMix/sonic-similarity as follow-ups

* fix(jellyfin): genre paging params and same-key casing collisions

getGenres read StartIndex/Limit in PascalCase, which normalizeQueryKeys had
already folded to lowercase, so genre paging was silently ignored; totals now
come from the full (small) genre list instead of the page length.
normalizeQueryKeys now merges values when two casings of a key collide,
instead of nondeterministically keeping one.

* fix(jellyfin): round ratings to the nearest star instead of truncating

Rating is a nullable double 0-10 in Jellyfin's contract. Truncating integer
division stored 9 as 4 stars, and both Rating=1 and fractional values (which
failed integer parsing) became 0 — silently deleting the rating. Parse as
float, round, and floor nonzero input at one star.

* fix(jellyfin): apply Name/IsPublic sent together with a track replacement

Jellyfin's UpdatePlaylist applies every provided field, but the Ids branch
returned early, silently discarding a rename or visibility change sent in the
same body (core/playlists.Create with an existing id ignores the name).

* fix(jellyfin): don't rotate the stored server id on transient DB errors

serverID treated any Property.Get error as "no id yet" and persisted a fresh
UUID over JellyfinServerID, with sync.Once pinning it for the process lifetime
— a busy DB or canceled request context on the first request would break every
client's cached ServerId. Only ErrNotFound mints a new id now, and failures
yield an uncached temporary value so the next request retries.

* fix(jellyfin): report real search totals instead of page length or unfiltered counts

Artist search returned TotalRecordCount = len(page), so clients stopped after
the first page; album/song search counted via CountAll, which can't see the
search term, so clients paged through phantom results. The repos' Search API
has no match count, so fetch one row beyond the page: offset+len is exact on
the last page and a strictly growing lower bound before it — paging clients
terminate exactly at the last match.

* fix(jellyfin): browse playlists via the generic /Items path and resolve the playlists folder by id

A typeless /Items?ParentId=<playlistId> (legal in real Jellyfin, used by
generic clients) fell through to the MusicAlbum default and returned an empty
list; it now returns the playlist's tracks, paginated, with visibility
enforced by GetWithTracks. resolveItemByID also answers the synthetic
playlists-folder id the server itself advertises instead of 404ing it.

* perf(jellyfin): cap per-type queries in multi-type /Items requests

The multi-type merge path queried each type with a zero-value QueryOptions —
no LIMIT in SQL — materializing every matching row (each with embedded
MediaSources) just to slice out one page in memory. Each type now fetches at
most StartIndex+Limit rows, the worst case one type can contribute to the
merged window; totals still come from CountAll.

* fix(jellyfin): dedupe and bound the background Similar fetches

awaitSimilar spawned a detached, deadline-free goroutine per request; clients
re-polling after the empty quick-wait response piled up duplicate provider
chains (no singleflight anywhere below) racing writes on the same artist row.
Identical in-flight requests now share one fetch — keyed per user, since the
mapped items embed the user's annotations — and the background context gets a
one-minute deadline so a hung provider can't hold goroutines forever.

* fix(jellyfin): gate private playlist covers on the public image route

The unauthenticated image endpoint elevated every request to an admin context,
so anyone who knew or guessed a playlist id could fetch another user's private
uploaded cover. Library artwork still resolves elevated (Jellyfin clients fetch
images without auth headers), but playlist covers are now served only when the
playlist is public or the request's optional token identifies its owner or an
admin; everyone else gets the placeholder.

* fix(log): redact full api_key values, including JWTs

The api_key pattern matched only word characters, stopping at a JWT's first
'.' — the Jellyfin API embeds the session JWT as api_key in TranscodingUrl, so
request logs kept its payload and signature, enough to reconstruct a replayable
token by prepending the constant header. Match to the next query separator
instead, like the sibling s=/p=/jwt= patterns.

* fix(jellyfin): record LastLoginAt on Jellyfin logins

authenticateByName re-implements credential validation and skipped the
UpdateLastLoginAt call the web UI's validateLogin makes, so users who only log
in via Jellyfin clients showed a never/stale Last Login in the admin UI.

* perf(jellyfin): batch song resolution in /Items?ids= and playlist expansion

Both paths probed up to four repositories per client-supplied id. Songs — the
common case — now resolve via chunked media_file.id IN queries (same pattern
as playqueue's loadTracks); only the residue pays the container probes.

* fix(jellyfin): wait for the real Similar result instead of answering a cacheable empty list

The 500ms quick wait returned an empty 200 for any cold lookup —
indistinguishable from "no similar items exist", so clients cached the wrong
answer until an app restart. With fetches deduplicated, wait up to the agents'
HTTP timeout for the actual result; only a hung provider now yields the empty
fallback, and its fetch still warms the cache in the background. Also makes
the dedup test deterministic (the old one raced its release channel).

* refactor(tests): extract the shared e2e harness into tests/harness

The Subsonic and Jellyfin e2e suites each carried their own copy of the
golden-DB lifecycle (boot, seed users/library, scan, WAL snapshot), the
ATTACH-DATABASE restore, fixture-FS registration, and the SpyStreamer /
NoopFFmpeg doubles. Those now live in one importable package (same pattern as
core/storage/storagetest); fixture libraries and request helpers stay
per-suite since they encode each API's test expectations.

* docs(jellyfin): make comments concise

Compress the narrative comments accumulated during live client testing into
short why-only notes; keep the client quirks, security rationales and gotchas,
drop the exposition. Comments-only change (net -141 lines).

* fix(tests): silence gosec taint false-positive in harness snapshot write

The write moved from a _test.go file (which gosec skips) into the importable
harness package; the path derives from GinkgoT().TempDir().

* fix(jellyfin): route the current /UserFavoriteItems favorite endpoint

@jellyfin/sdk 0.13.0 (used by Jellify) posts favorites to
POST/DELETE /UserFavoriteItems/{itemId}, while we only routed the legacy
/Users/{userId}/FavoriteItems/{itemId} (Finamp). Jellify favorites 404'd
("Failed to add favourite"). Route both spellings to the same handlers.

* feat(jellyfin): honor Fields on /Items and add missing conformance fields

Match real Jellyfin's response shape: gate MediaSources (and MediaStreams)
behind Fields=MediaSources instead of always embedding them — clients that
need Size request it, as Finamp does — which cuts a 46-track artist response
from ~87KB to a fraction. Also emit the always-present fields Jellyfin sets:
ServerId (stamped centrally in ok), LocationType, HasLyrics, and SortName
(when Fields=SortName). PlaybackInfo still carries MediaSources (its purpose).

* fix(jellyfin): address code review security and correctness findings

Applies the reviewed findings from PR #5730:

- Gate similar songs/albums on the caller's library access, so the
  external provider can't surface metadata from libraries the user
  cannot see. Also clamp the client-supplied limit before it sizes any
  allocation or provider fetch (CodeQL user-controlled allocation).
- Prepend the /jellyfin mount prefix to the PlaybackInfo TranscodingUrl,
  so a client resolving it as an absolute host path still reaches the
  mounted router.
- Recognize WebP and GIF magic numbers on raw cover uploads, matching
  the formats Navidrome already supports.
- Bound the playlist cover upload: honor EnableArtworkUpload for
  non-admins and cap the body with MaxBytesReader/MaxImageUploadSize,
  mirroring the native image endpoint.
- Propagate non-not-found repository errors from resolveAnnotated as 500
  instead of silently returning 404.
- Normalize the literal prefix of mixed literal.param path segments
  (e.g. STREAM.mp3) so case-insensitive routing reaches stream.{container}.
- Rate-limit POST /Users/AuthenticateByName with the same per-IP limiter
  as /auth/login when AuthRequestLimit is set.
- Guard against a nil user in authenticateByName.

* fix(jellyfin): correct playlist track browsing and multi-id edits

Fixes three playlist issues, two found testing against Jellify and one
from the PR review:

- Resolve a playlist ParentId to its tracks even when the client sends
  IncludeItemTypes=Audio. Jellify opens a playlist with
  ParentId=<playlist>&IncludeItemTypes=Audio; the id was routed through
  listSongs as an album id, returning an empty list.
- Read repeated id query params (ids=X&ids=Y), not just the first value.
  Jellify's @jellyfin/sdk serializes id arrays as repeated params, so
  adding an album (which it expands client-side into many ids) only
  added the first track. Applies to both add and remove; the
  comma-separated form other clients use still works.
- Let an explicit empty Ids array clear a playlist. Ids is now a pointer
  so an omitted field still means 'leave unchanged', while an empty list
  clears the tracks (via RemoveTracks, since the repository skips track
  writes for an empty list).

* fix(jellyfin): register clients as players on any authenticated request

Jellyfin clients did not appear in the players list. Unlike Subsonic,
whose getPlayer middleware runs on every authenticated endpoint, the
Jellyfin router only registered a player on the /Sessions/Playing
reports, so browsing or streaming never created one.

Apply withPlayer to the whole authenticated group, mirroring Subsonic,
so the calling device registers (and scrobbling has a player) as soon as
it makes any authenticated request. Two follow-ups found while testing:

- Skip registration when the request carries no client/device info (no
  X-Emby-Authorization, e.g. the /socket handshake that auths via
  ?api_key= only), which otherwise created a junk player named ' []'.
- URL-decode the X-Emby-Authorization field values. Jellify's
  @jellyfin/sdk percent-encodes them (Device='Pixel%208%20Pro') while
  Finamp sends them raw, so the player name showed as
  'Jellify [Pixel%208%20Pro]'.

* refactor(jellyfin): move case-insensitive routing into the jellyfin package

The case-insensitive path normalization lived in the server package but
was only ever used by the Jellyfin router (its whole purpose is that
Jellyfin clients route case-insensitively while chi does not). Move it
into server/jellyfin and unexport it, so it sits with its only caller
and no longer needs to be exported across a package boundary.

* docs(jellyfin): document player registration, playlist and image behavior

Updates the package README for the behavior added/fixed this round:

- New 'Players and sessions' section: any authenticated request now
  registers the device as a player (like Subsonic), with the
  Client [Device] naming, URL-decoding of the Emby auth fields, and the
  /socket skip that avoids a nameless player.
- Authentication: note AuthenticateByName is rate-limited per IP.
- Playlists: repeated vs comma-separated id params, and that an explicit
  empty Ids clears the playlist while an omitted Ids leaves it untouched.
- Cover art: WebP/GIF magic-number detection plus the MaxImageUploadSize
  and EnableArtworkUpload gates.
- Endpoints table: add the /Similar and /UserFavoriteItems /
  /UserItems/.../UserData routes that were already served but unlisted.

* feat(jellyfin): expose configured users on the login user-picker

Adds Jellyfin.ExposedPublicUsers, a comma-separated allowlist of
usernames that GET /Users/Public advertises so Jellyfin clients (Finamp,
Jellify) can show a login user-picker instead of a blank username field.

The endpoint is unauthenticated, so it defaults to exposing no users and
never lists the full user table: only the admin-configured names are
returned, resolved live per request (a name that doesn't exist is skipped
and logged). Each entry is a minimal DTO (Name, Id) with no
Policy/Configuration, so admin status isn't leaked pre-login, and no
avatar since Navidrome has no per-user profile images.

* style(jellyfin): trim redundant comments

Remove comments that restated the code or duplicated an explanation
already given nearby, keeping the ones that capture non-obvious rationale
(client-specific quirks, gotchas). Comment-only change; no behavior
difference.

* perf(db): keep query planner statistics trustworthy with full ANALYZE

PRAGMA optimize's internal ANALYZE runs with a limited analysis budget
(~2000 rows) that writes wrong sqlite_stat1 entries for low-cardinality
indexes: on a 96K-track library it claimed (missing, library_id) narrows
to ~2000 rows when it matches the whole table. The planner then prefers
that index over the sort index and falls back to a full-table temp
B-tree sort per request, turning paginated song listings into
multi-second queries (reproduced at 5.5s on real hardware; ~90x slower
than with correct stats). Every index-creating migration re-triggered
the poisoning via the post-migration optimize, and the daily optimizer
could re-trigger it on large library changes. Setting analysis_limit on
the connection does not help: optimize ignores it.

Run a plain full ANALYZE instead: after migrations with schema changes,
and in db.Optimize (daily schedule and scan-end). Stats are stored in
the database file, so one connection suffices and the per-connection
pool loop is gone. The Optimize call at shutdown is removed: stats are
maintained at migration/scan/daily points, and an ANALYZE during
shutdown only delays it and races container stop timeouts.

* perf(db): add covering index for title-sorted song listings

Deep pagination over songs sorted by title (WHERE missing/library_id,
ORDER BY order_title LIMIT/OFFSET - the shape Jellyfin clients use to
enumerate the library, and non-admin native/Subsonic song lists share)
walked media_file_order_title and fetched the table row for every
skipped entry just to evaluate the filter and the annotation/bookmark
join keys: offset+limit random reads, seconds per page on cold spinning
disks.

The new (missing, library_id, order_title, id) index makes the offset
skip fully index-resident: filter columns and the join key come from the
index, and only the emitted page touches table rows. Measured on a
96K-track library: offset 50000 drops from ~6.5s (poisoned stats) /
~100ms (good stats, warm) to 24ms, and cold deep pages on NAS hardware
from ~7s to ~0.5s.

* feat(jellyfin): support transcoding via HLS playlist and server-forced player format

- withPlayer now propagates the player's configured transcoding into the
  request context (like Subsonic's getPlayer), so a format forced in
  Settings > Players applies to the Jellyfin stream endpoints
- new GET /Audio/{itemId}/main.m3u8, the endpoint Finamp plays through
  when its transcoding setting is enabled: a single-segment HLS VOD
  playlist pointing at the existing progressive transcode endpoint
- streamAudio: treat audioBitRate as bits/sec (Jellyfin convention) and
  fall back to audioCodec as target format when no container is given

* fix(jellyfin): honor GenreIds when browsing genre albums and tracks

Finamp's genre screen sends ParentId=<libraryId> plus GenreIds=<genreId>,
but /Items ignored the param, so every genre returned the whole library.

- filter.ByGenreID delegates to persistence.TagIDFilter (exported, was
  tagIDFilter), the same mechanism behind the native API's genre_id filter
- id lists are read via queryIDs, covering both spellings clients use
  (comma-separated and repeated params); /Items?ids= gains the repeated
  form too

* feat(jellyfin): filter album artists by GenreIds

Finamp's artist tab sends GenreIds to /Artists/AlbumArtists when a genre
filter is active; the param was ignored, returning all artists.

filter.ArtistsByGenreID matches artists credited as album artist on an
album with the genre, via a non-correlated semi-join over album
participants (86ms on a 29K-artist library; the correlated EXISTS form
takes 11 minutes). Applied on the browse path of /Artists* and
/Items?IncludeItemTypes=MusicArtist.

The performers variant (/Artists?GenreIds=) still ignores the filter: it
needs the same semi-join against media_file.participants, unmeasured on
large libraries.

* fix(jellyfin): version playlist image tag so clients refresh uploaded covers

Uploads were stored and served correctly, but Finamp kept showing the old
cover: it caches covers keyed by blurHash (its imageId is the item id,
which never changes), and both our image tag and synthetic blurhash were
derived from the playlist id alone.

The tag is now <id>-<UpdatedAt millis hex> (SetImage/RemoveImage go
through a full Put, which bumps UpdatedAt), and the blurhash derives from
the tag, so every cover change rotates both. UpdatedAt over-invalidates
(any playlist edit busts the cover cache), which only costs a refetch;
hashing the actual image remains the proper long-term tag.

An e2e test guards the whole chain, since a partial Put(pls, cols...)
would silently stop bumping UpdatedAt.

* fix(jellyfin): align cover upload limit and validation with the native endpoint

Cover uploads of large photos failed with a silent 400: the
MaxImageUploadSize cap was applied to the wire body, which Jellyfin
clients base64-encode (4/3 inflation), so the effective raw-image limit
was only ~7.5MB — and Finamp uploads picked photos uncompressed.

Align with the native endpoint:
- the limit caps the decoded image; the read cap allows for base64
  inflation
- validate by decoding (image.DecodeConfig) and take the storage
  extension from the real format instead of the Content-Type header,
  which clients get wrong (Finamp falls back to image/jpeg); a HEIC or
  corrupt file is now rejected instead of stored as a broken cover
- rejected uploads log the reason (size/limit/decode error); diagnosing
  this from production logs previously required guesswork

* fix(jellyfin): optimize SongsByArtistID filter to improve performance at library scale

Signed-off-by: Deluan <deluan@navidrome.org>

* fix(jellyfin): sort tracks by release year for SortBy=PremiereDate

Finamp's "Latest Releases" artist section sends
SortBy=PremiereDate,Album,... descending; PremiereDate wasn't in the
Audio sort map, so applySort fell through to Album and the view came
back in reverse album-name order (a 2002 remix album first, the 2013
release last).

Map premieredate/productionyear to the year sort key, matching the
ProductionYear the DTO exposes for songs and the existing MusicAlbum
mapping (premieredate -> max_year).

* feat(jellyfin): expose PremiereDate on tracks and albums

Finamp's "Latest Releases" artist/genre sections re-sort the merged
server responses client-side by PremiereDate and keep the top 5. Without
the field every comparison returns equal and Dart's unstable sort leaves
the picks in arbitrary order — a 2007 remix could lead the list even
with the server sorting by year correctly.

Serialize PremiereDate as ISO 8601 from the date tag (padding partial
"2007"/"2007-02" values so DateTime.tryParse accepts them), falling
back to the year; omitted when neither exists.

* feat(jellyfin): resolve Finamp-truncated item ids (saved queue restore)

Finamp persists its play queue by packing every item id into exactly 16
bytes (packIds assumes Jellyfin's 32-hex GUID ids), so our longer ids
come back truncated after an app restart and "Failed to restore queue"
loops forever: the /Items?ids= batch resolves nothing.

Navidrome ids can't be made GUID-shaped (nanoid ids can exceed 128 bits),
so compensate server-side: a 16-char id — a length no Navidrome id family
uses — is resolved by unique-prefix range scan, with ambiguity failing
safe. The ids= batch echoes the id as requested (Finamp matches restored
items by its stored ids), and stream, image, item, user-data, favorite,
rating and playback-report endpoints accept truncated ids transparently.

The proper fix belongs upstream in Finamp's packIds; documented in the
README so this layer can be removed once that ships.

* feat(jellyfin): implement Items/{id}/InstantMix

Finamp requests an instant mix on every track tap when its "start
instant mix for individual tracks" setting is on (plus the long-press
menus); the 404 made those taps fail with an error and play nothing.

A track seed returns itself first — Finamp plays exactly what comes
back — followed by the external provider's similar songs, capped at the
requested limit and filtered to the caller's libraries. Container seeds
(artist/album) return the provider's similar-songs blend. Provider
errors and unknown seeds degrade to seed-only/empty results instead of
404s, reusing the Similar endpoints' bounded-wait singleflight (with a
distinct cache key, since mixes and similar lists answer different
shapes). Sonic-similarity backing stays a follow-up (see README).

* style(jellyfin): trim wordy comments

* refactor(jellyfin): apply cleanup review findings

- batch truncated-id resolution in /Items?ids=: one chunked range query
  for all media-file prefixes instead of a query per id (a restored
  queue sends hundreds of truncated ids)
- resolve truncated ids on the /Similar endpoints too, matching the
  neighboring InstantMix; document which entry points don't resolve
- hoist maxImageUploadSize to core, deleting the byte-identical copies
  in nativeapi and jellyfin (tests moved to core)
- drop the unused type parameter on premiereDate

* fix(jellyfin): never drop the instant mix seed on a slow provider

The seed track was built inside the awaited provider fetch, so when the
external agent was slow or unreachable the request hit the 10s wait and
answered a fully empty mix — Finamp then played nothing on tap, even
though the seed needs no provider at all (seen live: Last.fm unreachable
from the server, responseSize=49).

Build the seed outside the await: only the similar-songs tail is fetched
and bounded, and a timeout now degrades to a seed-only mix. Also folds
instantMixForSong into getInstantMix, since the tail is exactly
similarSongs.

* fix(jellyfin): prefer the recommended Authorization scheme when picking a token

Jellyfin's authorization guidance deprecates X-Emby-Token,
X-MediaBrowser-Token, X-Emby-Authorization and api_key; the Authorization
MediaBrowser scheme is the recommended form. All spellings stay accepted,
but when a client sends several, the recommended one now wins. Adds
coverage for the canonical Authorization header, which no test exercised
directly.

* refactor(jellyfin): rename parseEmbyAuth to parseMediaBrowserAuth

The scheme is named MediaBrowser; the old name evoked the deprecated
X-Emby-* spellings even though the function also parses the recommended
Authorization header.

* fix(jellyfin): prefer the Authorization header over X-Emby-Authorization

The recommended header now wins when both carry MediaBrowser data — but
only when it actually parses as MediaBrowser: a reverse proxy may inject
Basic/Digest credentials into Authorization while the client sends the
deprecated header, and those must not swallow the client's auth.

* fix(jellyfin): require the MediaBrowser scheme when parsing auth headers

The parser extracted key="value" pairs from any Authorization value; a
foreign scheme whose parameters happened to use our field names would
have been misread as client auth. Validate the scheme word instead
(case-insensitively, per HTTP), accepting the legacy "Emby" spelling
like real Jellyfin. Replaces the any-recognized-field heuristic for
detecting proxy-injected Basic/Digest credentials.

* Revert "perf(db): keep query planner statistics trustworthy with full ANALYZE"

This reverts commit 118563e1053196f0e2e42dd4bee54e39a04ab145.
The planner-statistics work now lives in its own PR (#5740); this branch
keeps only the covering-index migration.

* fix(db): renumber jellyfin covering-index migration after master's latest

* fix(db): renumber Jellyfin covering-index migration

* docs(jellyfin): document playlist annotations

* refactor(log): clarify comments on external services query params

* refactor(e2e): move Subsonic e2e suite to server/subsonic/e2e

All files in server/e2e were Subsonic tests, so relocate the package
under server/subsonic/e2e to sit alongside the API it exercises. The
package name stays 'e2e'; only doc/comment references are updated.

* refactor(filter): consolidate genre filters and unexport tagIDFilter

Route filterByGenre, ByGenreID, and ArtistsByGenreID through a single
genreTagFilter helper so the EXISTS json_tree(tags,"$.genre") predicate
lives in one place. With server/filter no longer using it, persistence's
TagIDFilter is only referenced within the package, so unexport it.

feat(playlists): per-user starred/rating annotations (backend) (#5749)
* feat(playlists): add average_rating column to playlist table

* feat(playlists): store and read per-user starred/rating annotations

* feat(playlists): clean up annotations when a playlist is deleted

* feat(subsonic): route star/unstar of a playlist to the playlist repository

* feat(subsonic): route setRating of a playlist to the playlist repository

* test(subsonic): guard that playlist responses never expose annotations

* fix(playlists): clean stale mis-typed annotations on upgrade; cover GetAll read-back

* fix(playlists): scope annotation join by item_type and harden delete

Address code-review findings on the playlist-annotations branch:

- withAnnotation: add an item_type predicate to the LEFT JOIN so a
  mis-typed annotation row sharing an id can no longer leak into (or
  duplicate) another entity's read. Correct for every caller since each
  repo writes annotations with item_type = tableName. Regression test added.
- migration: reclassify legacy media_file-typed rows for playlist ids to
  item_type='playlist' (instead of deleting them), preserving users' prior
  playlist star/rating; run before the average_rating backfill so those
  ratings are included.
- playlist Delete: replace the per-request full-table cleanAnnotations()
  anti-join with a targeted, permission-safe (rows-affected gated),
  best-effort delete so a cleanup failure no longer misreports an
  already-committed delete as an error.
- MockPlaylistRepo: implement GetAll/IncPlayCount/ReassignAnnotation to
  remove the dead All field and the nil-interface panic traps.
- test: use slices.IndexFunc instead of a hand-rolled find loop.

* feat(playlists): streamline playlist deletion by relying on annotation sweep

* docs(playlists): trim comments in annotation migration and test

Condense the verbose comments added in this branch per the project's
comment-minimalism guideline, keeping only the non-obvious rationale.

The migration's reclassify block is shortened while preserving the safety
invariant (playlist and media_file ids never collide, so the item_type
rewrite touches only mis-typed rows and cannot violate the unique key) and
the ordering note. The redundant 'Populate average_rating' comment is
dropped since the UPDATE is self-evident. The repository test's leakage
comment is condensed to two lines. No code behavior changes.

* refactor(subsonic): resolve setStar targets via GetEntityByID

Replace setStar's Album/Artist/Playlist Exists probe chain with a single
model.GetEntityByID lookup and a type switch, mirroring setRating. This
removes three per-id existence queries and keeps the two annotation paths
consistent.

An id that resolves to no known entity is logged and skipped rather than
filed as a spurious media_file annotation, and a lookup failure on one id no
longer aborts the whole batch. Also drop a duplicate empty-ids guard.

* refactor(playlists): drop no-op reclassify/backfill from migration

The average_rating migration carried two data-fix UPDATEs that are no-ops on
any real database:

- The media_file->playlist reclassification only matches rows no released
  build ever created: playlists were never annotatable, so star/setRating of
  a playlist id was never written as item_type='playlist'. Any stray
  media_file-typed row for a playlist id is already removed by the media_file
  annotation GC sweep (item_id not in media_file).
- The average_rating backfill runs before any item_type='playlist' row can
  exist, so it can only ever write the default 0. Going forward SetRating
  keeps average_rating current via updateAvgRating.

Reduce the migration to the column add/drop.

* refactor(persistence): bind annotation join params, derive idField from tableName

Address PR review: use Squirrel parameter binding for item_type/user_id in
the shared withAnnotation join instead of string concatenation, and pass
r.tableName+".id" from selectPlaylist so the join field stays consistent
with the surrounding r.tableName usage.

* fix(subsonic): surface datastore errors in setStar instead of skipping

Address PR review: setStar swallowed every GetEntityByID error and continued,
so a real datastore failure would still commit the transaction and emit a
refresh event as if the star succeeded. Skip only on model.ErrNotFound (an
unknown id); return any other error so the request fails and rolls back.

* test(subsonic): assert absent JSON keys instead of substring matches

Address PR review: substring checks are brittle ("starred" matches "starredAt",
"rating" matches "userRating"). Unmarshal the response and assert the
annotation keys are absent.

* fix(subsonic): skip refresh broadcast when a star request changes nothing

Address PR review (Codex): once setStar began skipping unknown ids, a request
containing only unresolvable ids left the RefreshResource empty, which
SendMessage serializes as a {*:*} wildcard that forces every client to
refresh. Only broadcast when at least one id was actually starred.

* fix(db): rebase playlist average_rating migration timestamp past master

The 20260708011823 migration predated the newest migration merged to
master (20260712211040_add_primary_key...), which Goose would silently
skip on already-upgraded databases. Rename it to a current timestamp so
it applies in order.

perf(db): keep query planner statistics trustworthy with full ANALYZE (#5740)
* perf(db): keep query planner statistics trustworthy with full ANALYZE

PRAGMA optimize's internal ANALYZE runs with a limited analysis budget
(~2000 rows) that writes wrong sqlite_stat1 entries for low-cardinality
indexes: on a 96K-track library it claimed (missing, library_id) narrows
to ~2000 rows when it matches the whole table. The planner then prefers
that index over the sort index and falls back to a full-table temp
B-tree sort per request, turning paginated song listings into
multi-second queries (reproduced at 5.5s on real hardware; ~90x slower
than with correct stats). Every index-creating migration re-triggered
the poisoning via the post-migration optimize, and the daily optimizer
could re-trigger it on large library changes. Setting analysis_limit on
the connection does not help: optimize ignores it.

Run a plain full ANALYZE instead: after migrations with schema changes,
and in db.Optimize (daily schedule and scan-end). Stats are stored in
the database file, so one connection suffices and the per-connection
pool loop is gone. The Optimize call at shutdown is removed: stats are
maintained at migration/scan/daily points, and an ANALYZE during
shutdown only delays it and races container stop timeouts.

* perf(db): drop startup PRAGMA optimize that re-poisons planner stats

The startup PRAGMA optimize=0x10002 runs SQLite's budget-limited internal
ANALYZE (bit 0x02), which writes truncated sqlite_stat1 rows for
low-cardinality indexes -- the exact statistics-poisoning this PR set out to
eliminate. Because DevOptimizeDB defaults to true, a restart with no pending
migrations would re-poison the planner until the next scan or daily Optimize.

Remove it: statistics are already refreshed with a full ANALYZE after
schema-changing migrations (Init) and via Optimize at scan-end and on the daily
schedule, so nothing on the startup path needs to touch them. Also clarify that
Optimize is a no-op unless DevOptimizeDB is enabled.

* chore(db): remove the DevOptimizeDB flag and skip Optimize on quick scans

The flag only gated the optimize/ANALYZE maintenance calls and there is
no reason to leave planner statistics unmaintained; the guards are gone
along with the flag. The scan-end Optimize now runs only after full
scans — quick scans barely move the statistics, and the daily schedule
covers drift.

* style(scanner): drop redundant comment in runOptimize

* chore(persistence): drop the no-op PRAGMA optimize from ScanEnd

Mask 0x10000 only selects candidate tables by size change; without the
0x02 action bit optimize does nothing (verified: sqlite_stat1 stays
stale after a 100x table growth). The scan-end statistics refresh is
db.Optimize's full ANALYZE, and the expression-collation-index concern
the old comment guarded against no longer applies.

* fix(scanner): run the post-scan ANALYZE in the server process

With the external scanner (the default), the scan pipeline runs in a
subprocess, so its ANALYZE was invisible to the server: SQLite loads
sqlite_stat1 into the process's shared schema cache, and an ANALYZE from
another process does not refresh it — verified with the production DSN
that even brand-new pool connections keep planning with the old
statistics until the server restarts. An in-process ANALYZE, by
contrast, is immediately visible to every pooled connection through the
same shared cache.

Move the full-scan Optimize from the scanner pipeline to the scan
controller, which always runs in the server process.

* fix(scanner): honor promoted full scans in the optimize gate

A quick scan resuming an interrupted full scan is promoted inside the
scanner (possibly in a subprocess); mirror the promotion in the
controller so the post-scan ANALYZE isn't skipped.

* refactor: apply cleanup review findings

- drop forceFullRescan's inline ANALYZE: Init already runs a full
  ANALYZE after any migration batch with schema changes, so upgrades
  including a full-rescan migration analyzed the whole DB twice
- resumingFullScan uses a filtered CountAll instead of fetching and
  scanning all libraries
- document why CallScan (CLI) deliberately skips the post-scan Optimize

* perf(db): make planner analysis maintenance resilient

Check analysis freshness every 30 minutes and refresh statistics when the last successful run is over 24 hours old or a scan marked them pending. Persist successful analysis state, retry skipped or failed maintenance, coordinate checks with scans, and cover standalone CLI full scans.

* perf(db): avoid analyzing routine quick-scan changes

Reserve pending analysis for full scans, unscanned libraries, and retry state. Incremental quick scans now rely on the 24-hour freshness window instead of triggering a full ANALYZE at the next maintenance check.

* fix(scan): analyze resumed full scans in CLI

* fix(db): back off failed analysis retries

* feat(db): allow disabling scheduled analysis

* test(db): remove redundant analysis coverage

* refactor(db): split ANALYZE maintenance into optimize.go and dedupe call sites

- move query-planner statistics code from db.go to its own optimize.go
  (and matching optimize_test.go)
- log ANALYZE elapsed time inside Optimize/OptimizeIfNeeded instead of
  repeating the timing block at every call site
- drop the LastDBAnalyzeAttemptAt write on success: it is only read
  while failures >= 1, and every failure rewrites it first
- extract runPostScanAnalysis (cmd) and anyIncludedLibrary (scanner)
  helpers

fix(plugins): discard buffered scrobbles when a plugin is removed (#5737)
* fix(plugins): discard buffered scrobbles when a plugin is removed

Scrobbles are buffered in the DB per service, keyed by the plugin name.
When a plugin was removed (deleted from the plugins folder and detected by
the sync), its pending buffer entries were left behind forever: the drain
goroutine is stopped on the next scrobbler refresh, so the rows were never
retried nor discarded. Worse, if a plugin with the same name was installed
later, the stale entries would be drained into it - potentially a completely
unrelated plugin that just reuses the name.

Add a Discard(service) method to ScrobbleBufferRepository and call it from
removePluginFromDB, right after the plugin record is deleted. Disabling a
plugin intentionally keeps its buffered scrobbles, consistent with the
buffer's purpose of surviving temporary outages, and transient unload/reload
cycles during config updates are unaffected since they never delete the
plugin record.

* fix(plugins): don't wipe builtin scrobbler queues on plugin removal

Buffer entries are keyed by service name only, and removePluginFromDB runs
for any removed plugin file, so removing a plugin named e.g. lastfm.ndp -
regardless of its capability - would discard the builtin Last.fm retry
queue. Skip the discard when the plugin name is owned by a registered
builtin scrobbler, exposed via a new scrobbler.IsBuiltinScrobbler helper.
Reported by Codex review on the PR.

Also drop the testBroker usage from the new removePluginFromDB spec: it is
defined in manager_test.go which is excluded on Windows, breaking the
Windows test build. sendPluginRefreshEvent is nil-safe, so no broker is
needed.

perf(db): index media_file album/artist sort orders (#5706)
* perf(db): add composite indexes for song list album/artist sorts

The media_file sort mappings for album, artist and albumArtist expand to
multi-column ORDER BY clauses that no existing index could satisfy, so SQLite
fell back to a full table scan plus a temp B-tree sort of every row (including
the large lyrics/tags/full_text columns) even for a single 15-item page. On a
96K-track library this made /api/song?_sort=album take 3.6s on a cold cache.

Add composite indexes matching the three sort mappings, allowing the query to
walk the index and stop at the page size, in both directions. Drop the now
redundant single-column order_album_name/order_artist_name indexes (strict
prefixes of the new composites) and three indexes with no query path:
birth_time is only read in Go code, and artist/album_artist text column
lookups go through the media_file_artists table instead.

* fix(ui): make composer and track number columns non-sortable in song list

Clicking the Composer header was a silent no-op: composer is not a media_file
column, so the native API's sanitizeSort drops the sort and returns rows in
table order. Track number sorting across the whole library is not meaningful
and cannot use an index (the existing index leads with disc_number). Mark both
columns sortable={false}, like quality and mood.

* test(persistence): add sort index coverage test for large tables

Guard against sort options silently losing index support: every sort mapping
on media_file, album and artist is now verified with EXPLAIN QUERY PLAN to be
satisfiable by an index (both directions), so adding a mapping or dropping an
index that reintroduces a full-table temp B-tree sort fails the test. Sorts
that genuinely cannot use an index (random, annotation-join columns, JSON
expressions) must be declared in an exceptions list with the reason, keeping
the trade-off visible in review.

To make the sort mappings the complete declared sort surface, add identity
mappings for the media_file columns the UI sorts by without a mapping (year,
genre, duration, channels, bpm, path, comment, play_count, play_date, rating).
These are behaviorally no-ops: the same ORDER BY was previously produced by
the field whitelist fallback.

* perf(db): drop PreferSortTags expression indexes from media_file

The media_file sort_title/sort_artist_name/sort_album_name expression indexes
are only usable when PreferSortTags is enabled - a config reported by ~0.1% of
installations (insights, week of 2026-06-22) - yet every install pays their
storage (~8.6MB on a 96K-track library) and scanner write overhead. Drop them:
PreferSortTags installs fall back to a full sort for title/artist/album orders,
everyone else gets smaller DBs and cheaper writes. The order_album_name and
order_artist_name collation checks remain valid, now satisfied by the composite
sort indexes.

feat(search): rank exact matches above prefix matches (#5704)
* feat(search): boost exact token matches over prefix matches

buildFTS5Query now emits (word OR word*) instead of word* for plain tokens. The match set is unchanged (exact is a subset of prefix), but bm25 gives the rare exact token a high-IDF contribution, so rows containing the literal query word rank above prefix-only matches. The degraded-query check keeps evaluating the plain prefix form, preserving the LIKE fallback for queries like "1+" and "C++".

* feat(search): weight artist search_normalized equal to name in bm25

For the artist table, search_normalized holds only the artist's name in alternate spelling (transliterated/punctuation-stripped), so a hit there is as meaningful as a name hit. Combined with exact-token boosting, artists like MØ now rank in the top results for the query "MO" instead of dead last. media_file and album keep weight 1.0 because their search_normalized mixes title, album, and artist variants.

* test(persistence): add exact-match ranking regression test

Seeds MØ, Morrissey, and Modest Mouse and asserts MØ ranks first for the queries "MO" and "MØ": the exact transliterated hit in search_normalized must outrank name-prefix matches. The corpus deliberately has no competing exact-word names, since exact-vs-exact ordering depends on corpus statistics rather than the guaranteed exact-over-prefix property. Rows are inserted per-test (with their library_artist associations) and cleaned up to avoid disturbing the shared seed fixtures and their count assertions.

* docs(search): document exact-token OR emission in buildFTS5Query

* test(persistence): harden exact-match ranking test fixtures

Register the corpus cleanup before the insert loop so a mid-loop assertion failure cannot leak fts-rank-% rows into the shared integration DB, and reuse the existing createArtistWithLibrary helper instead of hand-rolling Put+AddArtist (which also replaces the ad-hoc context.TODO with the helper's GinkgoT().Context).

* fix(search): flag multi-word degraded queries for the LIKE fallback

The degradation probe was joined with explicit " AND " like the real query, so ftsQueryDegraded counted the literal AND as a long token and never flagged queries where every term degrades to a short token (e.g. "1+ 2+"). This predates this branch (the old code passed the same AND-joined string), but the probe now exists separately, so join it with spaces — it only feeds ftsQueryDegraded, which needs no explicit operators.

fix(search): artists with atomic non-ASCII names unfindable after FTS5 migration (#5703)
* fix(scanner): update artist search_normalized when rescanning

The FTS5 migration back-fills artist.search_normalized with a SQL
punctuation-strip approximation, relying on the next scan to compute the
precise value in Go (normalizeForFTS transliterates atomic letters like
Ø/æ/ß that FTS5's remove_diacritics cannot fold). But the scanner
persisted artists with an explicit column list that omitted
search_normalized, so not even a full scan ever repaired it: an artist
migrated from a pre-FTS database (e.g. "GØGGS") stayed unfindable by
any ASCII search, while their albums and songs, which are saved with all
columns, were fixed by a full scan. Add search_normalized to the column
list so a full scan re-indexes the artist via the artist_fts trigger.

* refactor(persistence): move normalizeForFTS to utils/str

Export it as str.NormalizeForFTS so the upcoming migration can reuse the
exact index-time normalization. Migrations cannot import the persistence
package (persistence -> db -> db/migrations would be an import cycle).

* fix(persistence): backfill artist search_normalized via migration

Recompute artist.search_normalized with the precise Go normalization for
databases migrated from pre-FTS5 versions, where the SQL back-fill could
not transliterate atomic letters (Ø/æ/ß) and the scanner never rewrote
the column. Only changed rows are updated, so the artist_fts update
trigger re-indexes exactly the affected artists, making artists like
GØGGS or MØ findable again without requiring a full scan.

* refactor(persistence): share FTS punctuation-strip regex via utils/str

Index-time normalization (NormalizeForFTS) and query-time processing
(buildFTS5Query/ftsQueryDegraded) must produce matching tokens, so keep
the punctuation-strip pattern in a single exported symbol instead of two
identical private copies that could drift. Also document that derived
columns computed in dbArtist.PostMapArgs must be listed in the scanner's
artist Put, which is how search_normalized went stale in the first place.

* chore(migrations): announce artist search backfill in the log

Match the FTS5 migration's notice() pattern so startup isn't silent
while the backfill runs on large libraries.

* docs: tighten comments added in this branch

* docs: describe FTSPunctStrip by what it matches, not one replacement

test(db): fix flaky applyLibraryFilter specs on shared DB (#5697)
The 'sees all libraries' specs hard-coded the user's libraries as {1, 2}
and assumed the shared test DB held exactly two libraries. applyLibraryFilter
only skips the filter when granted count == total library count, so when
another spec left an extra library behind (Ginkgo randomizes spec order),
the count was 3, the filter was applied, and the SQL assertion failed. This
surfaced on the Windows CI run but reproduces on any platform.

Grant the user exactly the library IDs that actually exist in the DB at
runtime instead of hard-coding them.

perf(db): skip library filter when a non-admin sees all libraries (#5696)
* perf(db): skip library filter when a non-admin sees all libraries

applyLibraryFilter already short-circuits for admins and headless
contexts, but a non-admin who has been granted every library still paid
for the correlated user_library subquery, which filters out nothing yet
is the slow non-admin list/count path.

Reuse the visibility check search3 already had: skip the subquery when
the user's granted libraries cover the whole library table. The two
helpers (userSeesAllLibraries/visibleLibraryIDs) are promoted from
artist_repository to the base sqlRepository so all ~13 call sites
benefit and search3 shares the single implementation.

The skip is strictly gated on granted count >= total library count,
never on an empty/unknown library set, so access control is unchanged
for restricted users.

* refactor(db): make all-libraries skip fail closed; test cleanups

- userSeesAllLibraries: require len(visible) == total (not >=) so the
  filter skip can never over-grant if the visible set is ever inflated.
- tests: assert ToSql() returns no error; restore r.db in AfterEach to
  avoid leaking mutated state to other specs.

perf(db): skip annotation join in CountAll when unused (#5694)
* perf(persistence): skip annotation join in CountAll when unused

The Native API list endpoints (/api/song, /api/album, /api/artist) issue a
pagination count on every request via rest.GetAll. CountAll unconditionally
added a LEFT JOIN on the annotation table to a count(distinct id) query. The
join's columns are stripped by count(), but the distinct-over-join forced
SQLite to stream and dedup every row, making the count dominate the request
time on large libraries (e.g. ~190ms cold for 95k songs, seconds for
non-admin users behind the library subquery).

Gate the annotation join: only add it when a filter actually references an
annotation column. The need is detected by rendering the query to SQL and
matching annotation column names as whole words, which covers both named
filters (starred, has_rating) and raw squirrel filters. The column set is
derived from model.Annotations so it tracks schema changes; average_rating is
excluded because it lives on the base table, and word-boundary matching keeps
it from matching the annotation column rating.

Counts are unchanged; only the query plan changes. Unfiltered song counts drop
from ~37ms to ~4ms (warm) on a 95k-song library.

* test(persistence): make annotation-join detection case-insensitive

Address review feedback: SQLite column names are case-insensitive, so a raw
filter using e.g. "RATING" would previously evade the case-sensitive column
regex and wrongly drop the annotation join. Add the (?i) flag (average_rating
stays excluded — the underscore still prevents a word boundary before rating)
and cover it with mixed-case tests. Also make the starred-count assertion an
exact value instead of a range.

fix(subsonic): make "recently added" order reproducible and consistent with RecentlyAddedByModTime (#5678)
* fix(subsonic): align album `created` with RecentlyAddedByModTime sort

The album `created` attribute returned by search3, getAlbumList2 and the
other album endpoints was always sourced from the album's CreatedAt (oldest
song birth time), while the "recently added" sort is governed by
RecentlyAddedByModTime: it orders by album.updated_at when that option is
enabled and album.created_at otherwise.

As a result, when RecentlyAddedByModTime was enabled, clients that cache
album results and sort locally by `created` (e.g. for a "Date added" view)
could not reproduce the order returned by getAlbumList2?type=newest, since
the exposed value did not match the column driving the sort.

Make albumCreatedAt config-aware so the primary timestamp it returns mirrors
recentlyAddedSort: UpdatedAt when RecentlyAddedByModTime is set, CreatedAt
otherwise. The existing zero-value fallback chain is preserved so this
required OpenSubsonic field is never emitted as zero on legacy rows.

Note: this is a behavior change for the contractual `created` attribute. With
RecentlyAddedByModTime enabled, an album's reported `created` now reflects the
newest song modification time and can change when files are modified.

Scope is limited to albums; the song-level `created` (BirthTime) is unchanged.

* fix(subsonic): order Recently Added by full-precision timestamp with tiebreak

The recently_added sort wrapped the timestamp in datetime(), truncating it
to whole seconds, and had no secondary sort key. Album timestamps carry
sub-second precision (aggregated from song file birth-times), so on a fresh
scan many albums tie at the second; SQLite then returns ties in query-plan
order, which changes when a library filter is applied. This made the web UI
"Recently Added" order invert between library selections and diverge from
getAlbumList2?type=newest, and clients receiving the full-precision created
value could never reproduce the server order.

Sort on the raw, full-precision column with an album.id / media_file.id
tiebreak instead. A new migration swaps the album datetime() expression
indexes (and the plain media_file indexes) for composite (col, id) indexes
that cover the new sort. Timestamps were already normalized to space-format
by 20260316000000_normalize_timestamps, so raw-string comparison is safe.

* fix(subsonic): make song created follow RecentlyAddedByModTime

The song Created field returned BirthTime (file ctime), but the recently_added
sort (shared by the Subsonic and native APIs, and the web UI) orders by
created_at, or updated_at when RecentlyAddedByModTime is set. A Subsonic client,
which can only sort by the created value it receives, could therefore never
reproduce the server's "recently added" order in either mode.

Add mediaFileCreatedAt mirroring albumCreatedAt and use it for child.Created:
CreatedAt by default, UpdatedAt under RecentlyAddedByModTime, with BirthTime as
a legacy fallback. This aligns song created with the sort column, matching how
album created already works and what the native API/web UI present.

perf(smartplaylist): use annotation index for playcount/rating/loved filters (#5662)
* fix(smartplaylist): use annotation index for playcount/rating/loved filters

Annotation-field criteria wrapped the column in COALESCE(col, default) so
missing annotation rows behave as 0/false. COALESCE prevents SQLite from
using the column index, forcing a full media_file scan during smart playlist
materialization - multi-second loads on large libraries, independent of rule
complexity.

Store the raw column plus its default and drop COALESCE when the compared
value cannot match the default; fall back to 'col <op> ? OR col IS NULL' when
the default would match, so never-annotated tracks are still preserved.
Sorting keeps COALESCE to retain deterministic NULL ordering. Result set is
unchanged; the materialize query now seeks the annotation index.

Signed-off-by: Deluan <deluan@deluan.com>

* fix(smartplaylist): keep COALESCE for list-valued annotation comparisons

Hardening from final review: a list value (IN (...)) can't drive the index
and a default-inclusive list has per-element NULL semantics, so route slice
values through COALESCE(col, default) to stay exactly equivalent to the prior
form. Also make the bool-default branch explicit (loved only supports
equality operators) and share the COALESCE rendering via coalesceExpr.

* refactor(smartplaylist): make coalesced() a field method

Thermo-nuclear review follow-up: promote the free coalesceExpr(f) to a
smartPlaylistField.coalesced() method that returns the bare expression when
there is no default. This lets sortExpr call field.coalesced() unconditionally
and drop its 'if coalesceDefault != nil' branch, removing the 'only annotation
fields get coalesced' special case from the sort path. Behavior unchanged.

* fix(smartplaylist): keep COALESCE for LIKE, bool-ordering, and tag ranges

Code review (xhigh) found the index-friendly rewrite did not cover every
operator, breaking result-set equivalence on a few reachable raw-JSON paths:

- LIKE family (contains/startsWith/endsWith/notContains) on annotation fields
  used the bare column, so a NULL column never matched and missing-annotation
  rows were dropped.
- Ordering comparators (gt/lt/...) on bool fields (loved) were decided as
  equality, wrongly including never-annotated rows.
- InTheRange on a numeric tag split into two independent json_tree EXISTS,
  letting different tag values satisfy each bound.

Centralize the decision in annotationCond via bareNullInclusion: emit the
index-friendly bare form only for scalar values under an exactly-orderable
comparator, otherwise fall back to the COALESCE form (always equivalent to the
original). Route LIKE through coalesced(); reject tag/role ranges. Replace the
local toFloat/toBool with spf13/cast (fixes unhandled numeric types and string
bool forms), and drop the redundant LookupField + double reflect.TypeOf.

A 17-case brute-force check confirms row-set equivalence to the prior
COALESCE form across all operators including the fixed LIKE/bool cases.

* fix(smartplaylist): keep COALESCE for list values on bool annotation fields

Second review found the bareNullInclusion bool branch missed the non-scalar
guard the numeric branch has: a list value on loved/albumloved/artistloved
(e.g. {"is":{"loved":[true]}}) coerced through toBool (which swallowed the
cast error) to false, emitting the bare/OR-IS-NULL form and wrongly including
never-annotated rows. Make toBool return (value, ok) like toFloat and bail to
COALESCE when the value isn't a scalar bool. Also add the missing test for the
tag/role range rejection. A 21-case brute-force confirms row-set equivalence to
the original COALESCE form across every operator, including the bool/numeric
list paths.

* refactor(smartplaylist): drop spf13/cast for stdlib value coercion

The value coercion only sees the handful of types criteria produces (int,

instead, keeping the string fallback (ParseFloat/ParseBool) that closes the

unchanged), and the persistence layer reuses it via its existing model/criteria
import instead of a local helper. No behavior change.

* fix(smartplaylist): address review feedback on multi-field maps and *any

From the PR bot reviews:
- sqlFields now uses the field's coalesced() form, so annotation fields in a

  silently drop never-annotated rows. Covers both the comparison and LIKE
  fallback paths. (Gemini high, Copilot)
- Replace coalesceDefault *any with a plain any (0/false are non-nil
  interfaces, so nil still means 'no default'); drop the coalesce() boxing
  helper and the pointer indirection. (Gemini)
- Give rangeExpr clear, range-specific errors for the multi-field and malformed
  -pair cases instead of an empty-field / 'in operator' message. (Copilot)

Adds tests for the multi-field COALESCE behavior and the new range errors.

Signed-off-by: Deluan <deluan@deluan.com>

* Revert multi-field COALESCE handling (YAGNI)

The multi-field operator map case the bots flagged is unreachable: marshalExpression
rejects any operator map with more than one field, so a multi-field map can never be
persisted or loaded. Revert the sqlFields change and its tests rather than harden a
code path no supported input can reach. Keep the two reachable improvements from the
review: coalesceDefault any (not *any), and the clearer malformed-range error.

* refactor(persistence): model comparator as a behavior-carrying struct

The smart-playlist comparator was a bare string alias, forcing two parallel
switches over the same six operators: squirrelCmp mapped each to its squirrel
constructor, and bareNullInclusion restated each as a float predicate. Adding
or changing an operator meant editing both in sync.

Make comparator a struct that bundles those facts per operator (the squirrel
builder, the operator as a float predicate, and whether it's an ordering op).
Both switches collapse: squirrelCmp is deleted in favor of cmp.build, and
bareNullInclusion's numeric switch becomes a single cmp.satisfy call. Generated
SQL is unchanged, as the existing table-driven tests confirm.

* docs(smartplaylist): trim comments that restate the code

Remove or tighten comments that describe what the code already says (likeCond and
comparisonExpr doc lines, redundant clauses in annotationField/coalesced/ToBool/
normalizeBoolValue). Keep the comments that explain non-obvious rationale: the
COALESCE-vs-index tradeoff, the bareNullInclusion/annotationCond contracts, and the
why-we-fall-back notes.

* docs(smartplaylist): collapse coalesceDefault comment to one line

The field's six-line block duplicated the COALESCE-vs-index rationale that already
lives on annotationCond. Reduce it to a one-line description plus a pointer there.

fix(playlist/share): apply user library access to import and sharing paths (#5640)
* fix(playlist): respect the user's library access when resolving M3U paths

FindByPaths looked up paths across all libraries, so importing an M3U
could add tracks from libraries the importing user has no access to.
Apply the user's library filter to the lookup, matching every other
media_file read. Admins and the (admin-context) scanner are unaffected.

* fix(share): scope shared playlist tracks to the owner's libraries

loadMedia loaded playlist tracks with a fake-admin context, so a shared
playlist could include tracks from libraries the owner has no access to.
Load as the share owner instead, so the library filter applies.
Admin-owned shares are unchanged.

* fix(share): only serve shared tracks the owner can access

A shared stream fetched the media file by id without checking the share
owner's library access, so it could serve tracks from libraries the
owner has no access to. Gate share-scoped streams on the owner's library
access. Non-share streams are unaffected.

* test(share): tidy library-access test setup

Consolidate the repeated share-owner test fixture in handleStream into a
helper, assert on track fields with HaveField instead of building an id
slice, and delete the scratch media file through the public repository
method.

* style: trim verbose comments in library-access checks

* fix(share): guard against nil owner and clean up test users

Add a nil check after loading the share owner so a missing user yields a
clear error instead of a possible nil dereference, and delete the users
created by the new tests in their AfterEach blocks.

* fix(share): avoid panic when a shared playlist is no longer visible to its owner

Tracks() returns nil when the playlist can't be loaded under the owner's
context (e.g. a public playlist shared by a non-owner that was later made
private). Capture the result and return early instead of chaining GetAll
on a nil repository, leaving the share with no tracks.

perf(subsonic): speed up artist search3 deep-offset pagination (#5620)
* perf(subsonic): speed up artist search3 deep-offset pagination

Empty-query and FTS artist search (search3/search2) paginated via a
CROSS JOIN library_artist + DISTINCT in Phase 1 purely for library access
control. The DISTINCT forced a temp b-tree over the whole junction table on
every page, making deep offsets O(offset): ~200ms at offset 299k on 300k
artists.

Replace it with a join-free EXISTS predicate keyed on artist.id, backed by a
new covering index on library_artist(artist_id, library_id). EXISTS keeps
artist as the ordered driver and never fans out rowids, so Phase 1 stays a
plain ordered scan that LIMIT/OFFSET can short-circuit. Admin, headless, and
all-libraries users skip the filter entirely (the dominant case) for a flat
ordered walk over the primary key.

Measured on a 300k-artist / 1M-song library: admin/all-libs pagination is
~4.5-5.4x faster at depth (~180ms to ~33ms at offset 400k); restricted
subset users keep correct, gap-free pages while also getting faster.

The narrowing artist filter is applied at the subsonic layer only when the
request targets a strict subset of the user's libraries, so the common case
(and the admin fast-path) is never burdened with a redundant predicate.

* fix(subsonic): narrow artist search by library set, not count

narrowsArtistLibraries decided whether to add the subsonic-layer artist
narrowing filter by comparing len(requested) < len(accessible). musicFolderId
is not deduplicated, so duplicate IDs inflated the requested count: a user
requesting ?musicFolderId=1&musicFolderId=1&musicFolderId=2 against three
accessible libraries produced len([1,1,2])==3, which is not < 3, so the filter
was skipped and the user saw artists from the third library too.

Compare as set membership instead: the request narrows iff some accessible
library is absent from it (requested is always a subset of accessible, validated
upstream by selectedMusicFolderIds). This is immune to duplicate IDs. Add a
regression test that fails against the old length-based check.

Also consolidate the repeated EXISTS/no-DISTINCT/O(page) rationale that the
prior commit spread across five sites down to a single authoritative comment on
ArtistLibraryFilter, with the call sites referencing it.

* perf(subsonic): drop redundant library_artist covering index

The migration added an index on library_artist(artist_id, library_id) on the
theory that the restricted-subset artist-search EXISTS needed it to seek by
artist_id. Benchmarking on a 405k-artist / 5-library dataset showed no benefit:
the EXISTS subquery constrains both columns (artist_id = and library_id IN), so
SQLite already resolves it as a covering-index seek on the existing
(library_id, artist_id) UNIQUE autoindex. With the new index present the planner
still picks the autoindex and ignores it.

Drop the migration and correct the comment. Removing ~11MB of dead index plus
its write-amplification on every library_artist insert/delete, for zero query
gain.

* fix(scanner): mark artists missing when they lose their last library

Artist search Phase 1 filters on artist.missing and Phase 2 inner-joins
library_artist, so a non-missing artist with no library_artist row (an orphan)
takes a pagination slot in Phase 1 and then vanishes in Phase 2, shortening the
page and shifting deep offsets. The admin/headless search fast-path walks artist
unfiltered, so it is fully exposed to this.

Two paths created such orphans without updating artist.missing:
- RefreshStats deletes library_artist rows whose stats are '{}' (artist lost all
  content in a library) after every scan. This is the common source.
- Library deletion cascades away the library's library_artist rows.

Mark newly-orphaned artists missing at both sources, so the shared
'missing = false' search filter excludes them immediately instead of waiting for
a later scan. In RefreshStats the update only runs when the cleanup actually
removed rows (the only way a new orphan can appear), so steady-state scans pay
nothing; measured ~160ms on 300k artists only when orphans can exist.

* refactor(subsonic): address review feedback on artist search filter

Code-review follow-ups to the artist search pagination change:
- ArtistLibraryFilter: short-circuit to a constant-false predicate when no
  library IDs are given, avoiding a degenerate empty IN () subquery.
- ArtistLibraryFilter: add an inner LIMIT 1 to the correlated EXISTS so SQLite
  cannot flatten it into a fan-out join (an artist in multiple of the user's
  libraries would otherwise yield duplicate rowids and corrupt pagination).
- narrowsArtistLibraries: compare accessible-vs-requested as a set lookup
  instead of slices.Contains in a loop.
- searchConfig.LibraryFilter: document that a join-free filter is now a
  correctness requirement (DISTINCT was removed), not just a performance one.

* docs: trim verbose comments in artist search/orphan code

Condense the over-explained comments added in this PR to the essential 'why',
removing repeated cross-references and restatements of the adjacent code.

* fix(scanner): heal pre-existing orphan artists on full refresh

The orphan-marking added to RefreshStats only ran when its empty-stats cleanup
deleted rows, so it reconciled newly-created orphans but not ones already left
in the database by older versions (whose library_artist row was deleted before
this fix existed). Such legacy orphans would surface in the admin/headless search
fast-path as short/gappy pages.

Also run the orphan-marking on a full refresh (allArtists), so a full scan — which
upgrades commonly trigger and users can run manually — reconciles the backlog. No
migration needed; the runtime fixes prevent recurrence.

* perf(subsonic): extend artist search fast-path to all-library users

applyLibraryFilterToSearchQuery only skipped the library filter for admin and
headless processes. A regular (non-admin) user who can access every library has
the same result set as an admin, but was still given the EXISTS filter — an
O(offset) cost for a predicate that matches every non-missing artist anyway.

Skip the filter for them too, using a cheap library CountAll() (a count over the
tiny library table) compared against the user's library count. On any error it
falls back to the filtered path, which is correct, just slower.

* fix(scanner): log error as trailing arg, not explicit error key

Signed-off-by: Deluan <deluan@navidrome.org>

* test(scanner): e2e guard for orphan artists under PurgeMissing

Adds an end-to-end scanner test for the orphan-artist invariant fixed in
RefreshStats: with Scanner.PurgeMissing enabled, removing all of an artist's
files hard-deletes them, cascades away their media_file_artists rows, and
RefreshStats then drops the artist's emptied library_artist row. The test
asserts no non-missing artist is left without a library_artist row. Verified it
fails without the RefreshStats orphan-marking and passes with it.

* test(scanner): assert the orphaned artist is marked missing

The orphan e2e test only checked the aggregate no-orphan invariant
(orphanCount == 0), which a fully-deleted artist or an un-cleaned row would also
satisfy — so it could pass without exercising the fix. Assert Pink Floyd's row
specifically: missing=false before, missing=true after, and absent from the
non-missing results. Verified it fails without the RefreshStats orphan-marking.

* test(scanner): drop misleading non-missing-list assertion for orphan

GetAll has no default missing filter, but selectArtist inner-joins library_artist,
so an orphaned artist (no junction row) is excluded from the results whether or
not it is marked missing. The Not(ContainElement) check therefore passed for the
wrong reason. The direct floydMissing() == 1 query is the assertion that actually
validates the missing flag; keep that plus the orphan-count invariant and an
over-marking guard on The Beatles.

* test(scanner): document why orphan check reads the artist row directly

Clarify that GetAll cannot observe the orphan: selectArtist inner-joins
library_artist, so an artist with no junction row is excluded from results
whether or not it is marked missing. Asserting on GetAll would pass even without
the fix, so the test reads the artist row directly to check the missing flag.

* test(scanner): return descriptive artist state for clearer failures

floydState returns PRESENT/MISSING/NOT_FOUND instead of 0/1/-1, so a failure
reads '<string>: PRESENT to equal MISSING' rather than '0 to equal 1'.

* refactor(subsonic): keep artist library scoping in the repository

The search endpoint built a persistence-layer EXISTS predicate
(persistence.ArtistLibraryFilter) and injected it into artistOpts.Filters — the
only place the subsonic package reached into persistence, leaking a storage
detail up two layers.

Pass the same Eq{"library_id": ids} filter used for albums and songs, and let
the artist repository translate it to the join-free library_artist predicate
(scopeSearchToLibraries), where the junction knowledge belongs. The subset-vs-
fast-path decision moves there too, so narrowsArtistLibraries and the persistence
import are gone from the subsonic layer. Behavior is unchanged; coverage for the
translation moves to artist_repository_test.

* refactor(persistence): extract canonical markOrphansMissing helper

The 'mark non-missing artists with no library_artist row as missing' invariant
was hand-written as SQL in two places (RefreshStats and libraryRepository.Delete),
in two slightly different dialects (not exists vs id not in). Extract a single
artistRepository.markOrphansMissing method next to markMissing and call it from
both sites, so the invariant has one definition.

* fix(persistence): apply scoped library filter in both search phases

Two bugs from moving the artist library-scoping into the repository:

- Search() scoped opts.Filters for Phase 1 but still passed the original
  (unscoped) options to selectArtist, so Phase 2 re-applied the raw
  Eq{library_id} against the wrong columns and a restricted user's search
  returned nothing. Pass the scoped opts to both phases.

- scopeSearchToLibraries dropped the filter unconditionally for admins, so an
  admin explicitly narrowing via musicFolderId (e.g. search3?musicFolderId=2)
  leaked content from other libraries. Compare the request against the user's
  visible library set (all libraries for admin/headless), narrowing whenever it
  is a strict subset.

Both regressions were caught by the server/e2e multi-library suite.

* fix(core): delete library and reconcile orphans in one transaction

libraryRepository.Delete runs the FK-cascade delete and the orphaned-artist
reconciliation (markOrphansMissing) as two writes on r.db. Called directly they
autocommit separately, so an interruption between them could leave non-missing
artists with no library_artist row — the orphan state the artist search
fast-path forbids. Wrap the deletion in ds.WithTx at the core wrapper so both
writes commit atomically; the watcher/scanner/broker side-effects stay
post-commit.

* refactor(persistence): unify artist search library scoping into one filter

Phase 1 previously applied two overlapping library predicates: cfg.LibraryFilter
(scoped to the user's libraries) AND options.Filters (the requested subset),
producing two correlated EXISTS subqueries per rowid even though the request is
always a subset of the user's libraries. And the 'does this user see everything'
decision was implemented twice (userHasAllLibraries via CountAll vs
scopeSearchToLibraries via set-membership), with applyLibraryFilterToSearchQuery
as a third scoping path.

Resolve the effective library scope once in Search() via searchScope (intersect
the requested set with the user's visible libraries; nil = fast-path), clear
opts.Filters, and realize that single scope as the only Phase-1 LibraryFilter.
The visibility logic is now one pipeline: requestedLibraryIDs + visibleLibraryIDs
+ userSeesAllLibraries. Behavior unchanged; one EXISTS instead of two on the hot
path, one source of truth for library visibility.

* fix(persistence): harden artist search against malformed library_id filter

Search consumed only an Eq{"library_id": []int} filter; an Eq whose library_id
value wasn't []int slipped through unconsumed and would reach Phase 1's bare
artist table (no library_id column) → SQL error. Recognize any Eq carrying a
library_id key (isLibraryIDFilter) and always consume it, falling back to the
user's visible scope for a malformed value. Non-library filters are still left
in place for doSearch.

* refactor(persistence): trim redundant comments and unexport artist library filter

The artist-search-pagination work left dense explanatory comments, with the
join-free / LIMIT-1 anti-flatten rationale and the orphan-artist mechanics each
restated in several places. Consolidate each rationale into one canonical home
(artistLibraryFilter for the EXISTS/LIMIT-1 trick, markOrphansMissing for the
orphan lifecycle) and have the other sites reference it instead of repeating it.

Also unexport ArtistLibraryFilter to artistLibraryFilter: its only caller is
searchCfg in the same package and no test references it, so it never needed to
be part of the package's exported surface.

Comments only plus the rename; no behavior change.

* refactor: add slice.ToSet and use it for the artist search subset check

searchScope's subset test compared the requested libraries against the visible
set with a nested slices.Contains, which is O(visible * requested). On an instance
with many libraries (e.g. 100 libraries, a user granted 99) and an explicit
musicFolderId request, that is ~9.8k comparisons; with a set it is ~200.

Add a small reusable slice.ToSet helper (a slice -> map[T]struct{} set, collapsing
duplicates) and use it to make the membership lookups O(1), restoring O(n+m) without
the throwaway struct{}{} literal that an inline ToMap would need. No behavior change.

* refactor(artist): move artistLibraryFilter to artist_repository

perf(subsonic): speed up getRandomSongs with two-phase random-rowid selection (#5618)
getRandomSongs used a single ORDER BY random() over the media_file table. At large
library sizes that forces SQLite to scan the wide table and sort every matching row
before applying the limit — roughly 4 seconds for a 1M-track library, regardless of how
many songs are requested.

Add MediaFileRepository.GetRandom, which does this in two passes: first select N random
rowids over a narrow index (filters + library scope only, no wide columns or joins), so
the random sort runs over compact, index-friendly data; then hydrate just those rows with
the full select. The wide media_file row is never part of the sort. End-to-end this drops
getRandomSongs from ~4s to ~0.3s on a 1M-track library, and the cost no longer grows with
the requested size.

The handler now calls GetRandom directly. The filter helper that builds the genre/year
filters is renamed SongsByRandom -> SongsByGenreAndYearRange to reflect what it does, since
the random ordering is now owned by GetRandom rather than a Sort option. Filters (genre,
year, library) compose into the first pass unchanged. The album random list path is left
as-is (far fewer rows, already fast).

fix(scanner): import playlists skipped when no admin existed yet (#5609)
* fix(scanner): import playlists skipped when no admin existed yet (#5499)

On a fresh install the first scan runs before any admin user exists, so the
scanner's playlist phase skips all playlists (playlists are owned by the
first admin). Nothing re-imported them afterwards because folder selection
is gated on updated_at > last_scan_at, which nothing bumps.

The playlist phase now:
- resolves the admin at phase time (FindFirstAdmin) instead of trusting the
  context snapshot taken at scan start, so a long admin-less scan still
  imports playlists in its own phase if an admin was created meanwhile;
- records a persisted PlaylistsImportPending flag when no admin exists yet;
- when that flag is set, imports ALL playlist folders via a new
  GetAllWithPlaylists (bypassing the timestamp gate) and clears the flag.

Playlists are recovered by the next scan that runs with an admin, with no
dependency on scan duration and no changes to the auth/server layers.

* fix(scanner): surface datastore errors in playlist import deferral (#5499)

Address review feedback:
- distinguish model.ErrNotFound (no admin yet -> defer) from real datastore
  errors when resolving the admin, so DB failures are propagated, not swallowed;
- propagate the error if the pending-import flag can't be persisted, so a scan
  doesn't complete as successful without recording the recovery;
- surface read errors when checking the pending flag.

Also name the no-admin condition for readability.

perf(smartplaylists): merge negated artist/tag rules into one NOT EXISTS
* fix(smartplaylists): merge negated artist/tag rules in AND groups

Smart playlists with many negated role/tag conditions ANDed together (e.g.
100+ "isNot artist" rules, issue #5511) generated one correlated NOT EXISTS
subquery per rule, scanning media_file_artists for every candidate row. On
large libraries this took minutes and triggered API timeouts and SQLite lock
contention.

By De Morgan, "NOT EXISTS(role=X) AND NOT EXISTS(role=Y)" is equivalent to
"NOT EXISTS(role=X OR role=Y)", so multiple negated conditions for the same
field can be collapsed into a single batched NOT EXISTS. This mirrors the
existing OR-group merge that #5515 added for positive conditions.

The shared grouping/batching logic is extracted into mergeSameFieldConds,
parameterized by polarity, so the OR/positive and AND/negated paths reuse one
algorithm instead of duplicating it. roleCondGroup/tagCondGroup gain a 'not'
flag to emit the negated subquery.

Benchmark (323k tracks, 120 isNot artist rules, reporter's exact shape):
merged ~54ms vs unmerged ~8.7s steady-state (~160x faster).

* docs: trim redundant comments on merge helpers

The De Morgan explanation was repeated across three doc comments. Keep it in
one place (mergeNegatedJsonConds, where negation is introduced) and reduce the
shared core and group-type comments to concise one-liners.

fix(artwork): never serve artist folder images as album art (#5596)
* test(artwork): add failing e2e tests for artist image leaking as album art

Reproduces a v0.62.0 regression (#5451/#5457): the album cover-art
parent-folder fallback can include the artist folder, serving the artist
thumbnail (e.g. Artist/folder.jpg) as album art for any album without
image files in its own folder(s). Covers three scenarios: a plain
Artist/Album layout with no album images, a single-disc album spread
across sibling folders under the artist folder, and a spread album whose
own front.jpg is shadowed by the artist's cover.jpg via CoverArtPriority
order. Also adds an albumByName test helper for multi-album layouts.

The tests are expected to fail until the parent-folder inclusion is
gated by a structural check (skip the common parent when audio from
other albums lives under it).

* fix(artwork): never serve artist folder images as album art

The album cover-art parent-folder fallback (introduced in #5451/#5457)
could include the artist folder as a source of album images, serving the
artist thumbnail (e.g. Artist/folder.jpg) as cover art for any album
without image files in its own folder(s). This affected both plain
Artist/Album layouts and single-disc albums spread across sibling
folders under the artist folder.

Gate the common-parent inclusion with a structural check: the parent
only qualifies as an album root when no audio belonging to other albums
lives in it or anywhere beneath it. An artist folder contains other
albums' tracks, while an album root above disc subfolders contains only
this album's, so the check works for any disc folder naming scheme and
never affects the multi-disc fixes from #5376/#5456. A single-album
artist with no images anywhere remains structurally indistinguishable
from an album root and is a known residual case.

* refactor(artwork): move album-root audio check into folder repository

Replace the raw subtree SQL (LIKE/ESCAPE expression and wildcard
escaping) that lived in core/artwork with an explicit
FolderRepository.HasAudioOutsideFolders method, implemented in the
persistence layer next to the existing folder-subtree query pattern.
This also removes the test mock's brittle dispatch that sniffed the
generated SQL to recognize the query; the fake now overrides the new
method directly.

Extract the whole parent-folder resolution from loadAlbumFoldersPaths
into an albumRootParent helper, flattening four levels of nesting back
into a linear flow. Behavior is unchanged; the unit test for a parent
containing audio moved to the persistence suite, with added coverage
for subtree boundaries, missing folders, and LIKE-wildcard escaping in
folder paths.

* refactor(persistence): use exists helper in HasAudioOutsideFolders

Replace the hand-rolled count(*) query with the repository's canonical
exists helper, as suggested in PR review.

feat(smartplaylist): extend isMissing/isPresent to bpm, bitDepth and many text fields (#5603)
* feat(smartplaylist): support isMissing/isPresent on mbz_* and lyrics fields

Mark the six mbz_* MusicBrainz ID columns and the lyrics column as Nullable
in the criteria field map, then extend missingExpr to handle string columns
where absence is encoded as NULL or empty string (plus '[]' for lyrics). The
Numeric/Boolean path (ReplayGain) is preserved via an explicit type check.

* refactor(model): make MediaFile BPM and BitDepth nullable pointers

Convert BPM and BitDepth fields in model.MediaFile from int to *int so that
'tag absent' is distinguishable from zero. The metadata mapper now uses
NullableFloat for BPM (nil when absent or zero/unparseable) and only sets
BitDepth when the audio property is non-zero (lossy codecs report 0).

All read sites use gg.V() for zero-fallback deref so Subsonic API output and
transcoding behaviour are byte-identical to before. The persistence layer
bridges the existing NOT NULL DB columns by coercing nil to 0 on write and 0
back to nil on read in PostMapArgs/PostScan; a later migration task will drop
those constraints.

Hash upgrade safety is verified by a new MediaFile.Hash describe block: nil
*int hashes identically to the old int(0) default via ZeroNil+IgnoreZeroValue,
so no files will be spuriously re-imported after this change.

Extra files touched beyond the plan's list: core/stream/legacy_client_test.go
(BitDepth in model.MediaFile literals), persistence/mediafile_repository.go
(NOT NULL bridge).

* test(model): pin pre-conversion golden hashes for BPM/BitDepth

* feat(smartplaylist): support isMissing/isPresent on bpm and bitDepth

* feat(db): make bpm and bit_depth columns nullable, backfill 0 to NULL

Drop the NOT NULL constraint on media_file.bpm and bit_depth via a
lossless migration that converts legacy 0-means-absent values to real
NULL. Remove the temporary shim in PostScan/PostMapArgs that was bridging
the old NOT NULL columns to the *int model fields. Add round-trip
persistence tests asserting NULL storage for nil pointers and correct
value round-trip for non-nil pointers.

* test(e2e): verify isMissing/isPresent partition for nullable fields

Add DescribeTable covering bpm, bitdepth, lyrics, and mbz_recording_id:
for each field, isMissing + isPresent song counts must equal the total
library count, proving the nullable-column SQL is exhaustive and correct.

* test(e2e): seed bpm tag so isMissing/isPresent partition is non-trivial

* fix(model): omit bitDepth from JSON when absent instead of emitting null

* feat(smartplaylist): support isMissing/isPresent on more string fields

Enable isMissing/isPresent operators for album, comment, catalognumber,
discsubtitle, albumcomment, sorttitle, sortalbum, sortartist,
sortalbumartist, and explicitstatus by marking them Nullable in fieldMap.

* refactor(smartplaylist): unify missingExpr column logic into one flow

Collapse the numeric/string fork in missingExpr into a single
empties-driven loop (numeric/boolean fields simply have no empties),
and replace the duplicated IsTag/IsRole guard with a three-way switch
that expresses the dispatch model once. No SQL semantics change for
string fields; numeric/boolean fields now emit a single-element Or/And
which squirrel parenthesizes (e.g. `(col IS NULL)` instead of bare
`col IS NULL`) — update the affected test expectations accordingly.

fix(opensubsonic): make search3 empty-query pagination fast at large offsets (#5601)
* fix(subsonic): make search3 empty-query pagination fast at large offsets

Empty-query search3 (used by clients like Symfonium to sync the whole
library) degraded linearly with songOffset: the offset optimization in
optimizePagination keeps the original query's LEFT JOINs (annotation,
bookmark, library) inside its rowid NOT IN subquery, making it as slow as
plain OFFSET (~5s per page at offset 900K on a 920K-track library).

Rewrite the empty-query branch of doSearch to use the same two-phase
approach as the FTS search: Phase 1 paginates rowids on the bare main
table, which SQLite satisfies with a covering index at any offset; Phase 2
hydrates only the page's rows with all JOINs. The Phase 2 hydration logic
is extracted into hydrateRowidPage, now shared with ftsSearch.execute.

Also replace the media_file_missing index with a composite covering index
on (missing, library_id), so Phase 1 stays covering for non-admin users,
whose queries include a library_id filter. The composite serves all
missing-only lookups via its prefix.

With a 920K-track / 85K-album test library, search3 empty-query responses
are now flat (~0.1s) at every offset, for both admin and non-admin users
(previously 3-5s at offsets above 600K).

* refactor(persistence): share search Phase 1 contract and dedup junction fan-out

Extract the Phase 1 query assembly that was duplicated between the FTS
search and the empty-query search into executeTwoPhase: both paths now
supply only their strategy-specific FROM/JOINs and ORDER BY, while the
shared contract (missing filter, library access, options.Filters, and
Max/Offset semantics) lives in one place.

Also fix a pagination integrity bug: the artist library filter joins the
library_artist junction table, so an artist present in multiple libraries
produced duplicate rowids in Phase 1, corrupting offset-based pagination
(short pages and repeated artists during full-library syncs). Phase 1 now
applies DISTINCT whenever a junction-based LibraryFilter is set. DISTINCT
is used instead of GROUP BY because bm25() cannot be evaluated in a
grouped query; plain-filter tables (media_file, album) skip the dedup so
their Phase 1 keeps the streaming covering-index plan. This also fixes the
same duplication in the pre-existing FTS search path.

* fix(persistence): pin artist search Phase 1 join order with CROSS JOIN

search3 always filters artists by library (library_artist.library_id IN
...), and with the junction JOIN in the search Phase 1 rowid query SQLite
chose to drive from library_artist, sorting every junction row with a temp
b-tree on each page — a flat ~200ms penalty per request at 405K artists,
even at offset 0 (the previous code avoided this by accident: its GROUP BY
artist.id pinned an artist-driven plan).

Use CROSS JOIN (SQLite's explicit join-order override) in a search-only
variant of the artist library filter, keeping artist as the outer table so
Phase 1 streams rowids in artist.id order from the primary key index and
LIMIT/OFFSET short-circuits. The DISTINCT dedup stays and costs nothing
under the streaming plan. Other artist queries keep the planner's freedom.

With 405K artists, empty-query artist search is now 0.07s at offset 0 and
0.25s at offset 399K end-to-end (was 0.31s/0.34s before this fix, and up
to 1.2s on master at deep offsets). Artist FTS text search is unaffected.

fix(smartplaylist): support isMissing/isPresent operators on ReplayGain fields (#5585)
* fix(smartplaylist): support isMissing/isPresent operators on ReplayGain fields

ReplayGain values are stored in dedicated nullable columns (rg_album_gain,
rg_album_peak, rg_track_gain, rg_track_peak) rather than in the media_file.tags
JSON blob. The isMissing/isPresent operators previously only supported tag and
role fields, causing two failure modes:

1. Using the documented alias names (replaygain_album_gain etc.) from PR #5256:
   these got registered as JSON tags from mappings.yaml, so isMissing queried
   json_tree(media_file.tags, '$.replaygain_album_gain') which is always empty
   -> the playlist matched ALL songs.

2. Using the canonical field names (rgalbumgain etc.): not a tag/role, so SQL
   generation returned an error. Because refreshSmartPlaylist deletes old tracks
   before regenerating, the abort left the playlist empty.

Fix: add Nullable bool to FieldInfo and mark the four ReplayGain fields. Add
static alias entries (replaygain_album_gain -> rgalbumgain etc.) with
Numeric+Nullable set; because AddTagNames skips names already in the field map,
these static entries take precedence over the mappings.yaml tag registration.
missingExpr now emits IS NULL / IS NOT NULL for nullable column fields instead
of the json_tree lookup.

Fixes #5584

* chore(smartplaylist): address code review feedback

  removing the internal "nullable fields" jargon

1e7996f5d7 fix(share): enforce per-user ownership on share reads
Share repository read methods (Get, GetAll, Read, ReadAll, Exists, Count,
CountAll) did not apply an owner filter, so non-admin users saw shares
belonging to other users. The write paths already enforced per-user ownership;
this brings reads in line with them.

Add an addRestriction()/ownerFilter() based scope to share reads, keeping
admins and the headless public-share resolution path unrestricted. Route share
and player Delete through a new base-repo deleteOwned() primitive that applies
the ownership predicate in the DELETE's WHERE clause (atomic, no select-then-
delete window) and classifies a zero-row result as permission-denied vs
not-found, mirroring updateOwned. The addRestriction helper and the write-miss
classifier are hoisted onto the base repository so player and share share one
implementation.

Also map rest.ErrPermissionDenied and rest.ErrNotFound in the Subsonic error
handler so ownership/not-found failures from the rest-backed repositories
return the proper Subsonic codes (50 / 70) instead of a generic error.

Covered by unit tests (persistence, subsonic error mapping) and an end-to-end
cross-user sharing isolation test.

174621f259 fix(nativeapi): make /api/song path filter work and use startsWith (#5566)
The native API exposes a `path` query param on /api/song, but it was not
registered in the media file filter map. Unmapped real columns fall through
to a default LIKE predicate that emits an unqualified `path LIKE ?`. Since
the song query joins the library table (which also has a `path` column),
SQLite returned "ambiguous column name: path" and the request failed with
HTTP 500.

Register a dedicated path filter qualified to media_file.path, resolving the
ambiguity. The value is matched with startsWith semantics (LIKE arg || '%')
against the library-relative path stored in media_file.path.

To register it inline (without a one-off wrapper), startsWithFilter now takes
a bound field and returns a filterFunc, mirroring containsFilter. The two
existing callers are updated accordingly, and the now-unused withTableName
helper is removed. The user 'name' filter, which previously relied on
withTableName, is now qualified directly as user.name; tests are added to
guard that filter against the same column-ambiguity class (the user query
also joins the library table, which has a name column).
