1703b59d24 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.

3a155e23e8 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.

106a1e2501 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.

ca38e50c4f 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.

d28adb2676 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.

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.

fbce1d3500 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.

d921bb6a95 refactor(server): extract shared query filter builders to server/filter

0b9fbcd048 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).

b38750fd5b 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.

5e913ae6a4 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.

fix(scanner): stop logging expected lyrics sniff misses as warnings (#5702)
* fix(scanner): stop logging expected lyrics sniff misses as warnings

During a scan, embedded lyrics are parsed with an empty suffix, which puts
ParseLyrics into content-sniffing mode: it tries the TTML, SRT and Lyricsfile
YAML parsers in turn before falling back to plain text. Every plain-text or LRC
lyric therefore fails the structured probes on its way to the fallback, and each
failure was logged at warning level with no indication of which file triggered
it, flooding the scan log with benign "Error parsing lyrics, falling back to
plain text" messages.

A probe rejecting content it does not own during sniffing is expected control
flow, so it is now logged at trace instead. A parse failure under an explicitly
requested suffix (e.g. a malformed .yaml/.srt/.ttml sidecar) still warns, since
the user declared that format. ParseLyrics gains ctx and path parameters so any
warning names the offending file and carries request context where available;
all call sites are updated accordingly.

Also fixes a test-isolation bug in the new logging spec: the BeforeEach swapped
the process-global default logger via SetDefaultLogger but only restored the log
level on cleanup, leaking the null logger and its hook into later specs in the
shared model suite.

* test: use spec-scoped contexts instead of context.Background in lyrics tests

Replace context.Background() with GinkgoT().Context() (and b.Context() in the
parse benchmarks) across the lyrics-related tests, so contexts are cancelled
when each spec ends. The embeddedLyrics fixture in core/lyrics is now a
hand-written literal like its sibling fixtures, removing the construction-time
ParseLyrics call that could not use a spec-scoped context.

* refactor(model): attach lyrics parse log attribution via context

Narrow ParseLyrics back to (ctx, suffix, lang, contents), dropping the path
parameter added by the previous commit. Attribution now uses the codebase's
existing idiom: callers that know the source attach it with log.NewContext
(e.g. "file" for the media file or sidecar), and the plugin adapter tags both
the plugin name and the track, fixing probe-miss logs that misattributed
plugin-returned content to the file's own tags. This removes three adjacent
string parameters that were easy to swap silently, and the "" placeholder most
call sites had to pass.

Also hardens the logging spec from the previous commit: the null test logger is
now swapped in before raising the level (SetLevel forces the current default
logger to trace, so the old order left the null logger at info and trace
entries never reached the hook), the sniff test now asserts probe misses are
observable at trace with file attribution instead of only asserting the absence
of warnings, and cleanup restores the actual previous logger — via a new return
value on log.SetDefaultLogger — instead of a bare logrus.New() that would
discard hooks configured on the process-wide logger.

* refactor(lyrics): hoist attributed log contexts out of loops

Address review feedback on #5702: build the log-attributed context once per
operation instead of per iteration, and reuse it on the surrounding log calls
so the error/trace lines around ParseLyrics carry the same attribution fields.
In fromExternalFile the sidecar path now rides the context for all log lines
in the function, replacing the repeated explicit "path" field.

* style(model): pass lyrics parse errors as final log arguments

Per the project logging convention, errors go as the last argument (the log
package normalizes them via its error case) instead of a keyed "error" pair,
which stores the raw error value and bypasses that handling. Flagged by review
on #5702; the keyed form was inherited from the original warning line.

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.

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.

refactor(lyrics): single ParseLyrics entry point + all-format plugin lyrics (#5632)
* refactor(lyrics): read sidecar files via library storage FS

Routes fromExternalFile reads through storage.For(mf.LibraryPath) instead
of os.Open on AbsolutePath, fixing sidecar reads for non-local backends.
UTF-16 LE/BE and BOM handling preserved via ioutils.UTF8Reader.

* refactor(lyrics): address review feedback on sidecar FS read

- Move blank local-storage import from sources.go into lyrics_suite_test.go
  (the test suite already imports the local package for RegisterExtractor,
  so local's init() runs; production binaries get the scheme via normal wiring)
- Fix misleading comment: model.ParseLyrics → model.ParseLyricsFile
- Replace what-comment with why-comment in BeforeSuite explaining the
  log.Fatal guard that requires the no-op extractor registration

* test(lyrics): add subsonic e2e baseline for getLyrics endpoints

Establishes a behavioral baseline for getLyricsBySongId (v2 structured)
and getLyrics (legacy) before the lyrics parser refactor. Covers embedded
formats (LRC synced, plain text, TTML) and sidecar formats (LRC, SRT,
YAML), all isolated under a Lyrics/ fixture folder so the new fixtures
do not perturb existing test behavior beyond fixture counts.

Sidecar files are injected as raw &fstest.MapFile{Data: []byte(...)}
entries; the scanner skips non-audio extensions (.lrc, .srt, .yaml) so
they are invisible to scanning but reachable via the fake FS at request
time through fromExternalFile/storage.For.

Update album/artist/song counts in the album-list, multi-library, and
search3 empty-query tests to reflect the six new tracks (1 new artist,
1 new album, 6 new songs).

* test(lyrics): strengthen e2e lyrics baseline (lang assertions, rename helper)

Rename the local helper `main` to `firstLyric` to avoid collision with the
reserved-feeling built-in name. Add `Lang` assertions to both embedded and
sidecar DescribeTable entries, locking the current observed values: "xxx"
(ISO 639-2 "no language specified") for all embedded and LRC/SRT sidecars,
and "eng" for the YAML sidecar (which explicitly sets `language: eng`).

* feat(lyrics): detect Lyricsfile YAML in content-sniffing

* feat(plugins): content-sniff plugin lyrics for all formats

Replace model.ToLyrics (LRC/plain only) with model.ParseEmbedded so plugin
responses are content-sniffed for TTML, SRT, YAML, LRC, and plain text.
ParseEmbedded returns a LyricList, so the loop now flattens multiple tracks
per response entry.

The test-lyrics WASM plugin gains a "ttml" format mode (configured via
pdk.GetConfig) that returns a minimal TTML document; rebuilt with the
standard Go wasip1 toolchain (GOOS=wasip1 GOARCH=wasm). A new Ginkgo test
asserts Synced==true and the exact cue value, which the old plain-text path
could not produce.

GetLyrics doc comment updated to reflect content-sniffing; a later task will
retarget it to ParseLyrics once that function is introduced.

* test(plugins): validate plugin lyrics auto-detect across all formats

The test-lyrics WASM plugin now supports per-format modes via the
"format" config key: ttml, srt, yaml, lrc, and plain, in addition to
the existing default plain-text response. The plugin is rebuilt with the
standard Go wasip1 compiler.

lyrics_adapter_test.go gains a DescribeTable covering all five formats,
asserting both Synced (the discriminator that proves correct format
detection) and the exact line value. This validates the full
auto-detect chain (TTML → SRT → YAML/Lyricsfile → LRC → plain) end-to-end
through the real plugin → adapter → parser flow.

* refactor(lyrics): consolidate parsers into model.ParseLyrics

* refactor(lyrics): retarget legacy callers to model.ParseLyrics

Pin suffix to ".lrc" to preserve byte-identical output for stored
plain/LRC text that was previously handled by the now-removed ToLyrics.

* test(lyrics): fix lyrics tests after parser consolidation

- Rewrite the YAML-fallback test to assert the correct design: a
  non-Lyricsfile .yaml sidecar returns as plain text and shadows
  lower-priority sources (rather than falling through to .lrc).
- Add LibraryPath + relative Path split to the three subsonic tests
  that read sidecar files via storage.For(), so they resolve against
  the correct fixtures directory.
- Register a no-op extractor in api_suite_test.go BeforeSuite so
  newLocalStorage does not fatal when storage.For is called during
  sidecar-lyrics tests.

* test(lyrics): add per-format ParseLyrics benchmarks

Content-sniff path overhead: 1.5–15% depending on format.

* test(lyrics): use real public-domain fixtures for parser benchmarks

Replace synthetic benchmark payloads with 'Auld Lang Syne' (Robert Burns,
1788, public domain) rendered into every supported format (LRC, plain,
enhanced LRC, SRT, TTML, Lyricsfile YAML) so the numbers reflect realistic
content. Same song across formats makes per-format cost comparable.

Fixtures in tests/fixtures/lyrics/.

* fix(lyrics): preserve [] (not null) for empty lyrics in backfill migration

ParseLyrics returns nil for zero-line input (whitespace-only stored
lyrics). json.Marshal(nil LyricList) produces null, violating the DB
invariant that media_file.lyrics uses [] for empty lyrics, never null.
Initialize to model.LyricList{} when ParseLyrics returns nil so the
marshalled result is always [].

* refactor(lyrics): unify parser dispatch and centralize empty-list invariant

Apply thermo-nuclear review findings (behavior-preserving):

- Replace the suffix switch + three single-use closure adapters
  (parseTTMLKnown/parseSRTKnown + inline YAML closure) with a
  bySuffix map of a single lyricParser(lang, contents) signature.
  Normalize parseTTMLWithDefaultLang/parseSRTWithLanguage to that
  (lang, contents) order so no adapter glue is needed.
- Collapse the parallel sniffLyrics engine into one parseFirstMatch
  primitive shared by both the suffix and content-sniff paths
  (sniffOrder candidate list). TTML stays gated via parseTTMLIfDocument
  in sniff mode to avoid running the XML decoder on plain/LRC text.
- Add LyricList.MarshalJSON so empty/nil always serializes to [] (the
  lyrics column invariant), in one canonical place. Delete the
  migration's nil-guard, which the marshaler now subsumes.

Behavior verified unchanged: full suite + race + e2e green.

* refactor(lyrics): single registry drives both suffix dispatch and sniff order

Collapse the bySuffix map and sniffOrder slice into one ordered registry:
slice order is the content-sniff probe order, each row's suffixes drive
sidecar dispatch, and per-row bySuffix/byContent parsers preserve the
gated-TTML-when-sniffing distinction. One source of truth, no duplicated
parser references.

* refactor(lyrics): self-skipping parsers collapse the format table to one column

Move the TTML <tt>-document gate into parseTTMLWithDefaultLang itself (after
the encoding fixup, so UTF-16-declared docs are still recognized): non-TTML
content returns (nil, nil) to skip; a malformed <tt> document still errors.
SRT and Lyricsfile YAML already self-skip. With every structured parser
self-skipping, the format table drops to one {suffixes, parse} column named
lyricFormats — no bySuffix/byContent split, no separate sniff-only TTML gate.
Both the suffix and content-sniff paths share the same parser per format.

* refactor(lyrics): strip BOM once at ParseLyrics entry for all paths

Previously only the content-sniff path stripped the BOM; the suffix path
relied on its callers (fromExternalFile via UTF8Reader) having already
stripped it. That implicit contract was fragile — a caller passing raw
BOM-prefixed bytes with a suffix would reach the parsers with the BOM intact
(SanitizeText does not strip it). Strip once at entry so every path and
parser sees clean bytes regardless of caller. No-op for already-stripped
input.

* refactor(lyrics): trim verbose comments to essential why

* refactor(lyrics): move LRC parser to its own lyrics_lrc.go

Extract parseLRC, the enhanced-LRC helpers (parseEnhancedLine, adjustGroup,
stripEnhancedMarkers, shiftELRCCues), parseTime, and the LRC regexes from
lyrics.go into lyrics_lrc.go, with the parseLRC tests in lyrics_lrc_test.go.
This makes the layout symmetric — one file per format (lrc/srt/ttml/yaml) —
and leaves lyrics.go holding only shared types and cue normalization. All
moved symbols were already LRC-private; no behavior change.

* refactor(lyrics): collapse ParseLyrics suffix/sniff branches into one loop

Both modes differ only in which formats to try, so select candidates in a
single loop (all formats when sniffing, the suffix's own otherwise) and run
them through parseFirstMatch once. Drops the projected-slice make+index and
the ContainsFunc closure; unmatched suffixes yield no candidates and fall to
the plain-text floor, as before.

* refactor(lyrics): apply simplify-review cleanups

- stripBOM: bytes.TrimPrefix instead of []byte<->string round-trip (no alloc)
- ParseLyrics: pre-size the candidates slice
- move isTTMLDocument to lyrics_ttml.go beside its only caller (the dispatch
  layer should hold no per-format knowledge)

* refactor(lyrics): simplify test descriptions for structured lyrics

* refactor(lyrics): fold parseLyricsfile into lyricParser signature and rename file

- parseLyricsfile now matches the lyricParser signature directly (reads via
  bytes.NewReader), removing the parseLyricsfileBytes adapter and the
  string(contents) copy; the lyricFormats table references it directly.
- StructuredLyrics drops the vestigial LyricList{} init (json.Unmarshal
  overwrites; MarshalJSON owns the empty->[] invariant).
- Rename lyricsfile.go -> lyrics_lyricsfile.go (and its test) to match the
  lyrics_<format>.go convention used by lrc/srt/ttml.

* refactor(lyrics): move test-only parseTTML/parseSRT wrappers to test files

These zero-arg wrappers (defaulting lang to "xxx") had no production callers
after the consolidation — only the format tests used them. Move each beside
its tests so the production files carry no test-only code.

* build: exclude generated *_gen.go files from linting

The plugin host *_gen.go files (ndpgen output) were tripping the whitespace
linter despite carrying a generated marker. Exclude them by path so make lint
and the pre-push hook pass on untouched generated code.

* perf(lyrics): drop []byte/string round-trips in parsers

Apply code-review feedback to remove avoidable allocations in the lyrics
parsers. isTTMLDocument now takes []byte directly, so parseTTMLWithDefaultLang
no longer copies its buffer into a string before the TTML probe. parseSRTBlock
splits its block with strings.Split instead of converting to []byte and back
per line. ParseLyrics hoists strings.ToLower(suffix) out of the format loop.

No behavior change; the dropped len(scanner)==0 SRT guard was dead (strings.Split
never returns an empty slice, and the existing len(lines)==0 check still covers
empty input).

* refactor(lyrics): colocate and unexport cue-normalization helpers

Move the cue-normalization machinery out of lyrics.go into a dedicated
lyrics_normalize.go (with lyrics_normalize_test.go), leaving lyrics.go to hold
just the shared lyric types and their methods. lyrics.go was mixing the domain
type/contract definitions with format-agnostic post-processing.

Unexport normalizeLyrics, normalizeCueLines, and normalizeLineTiming: they have
no callers outside the model package, so they should not be part of its public
API. NormalizeCueEnds stays exported because the Subsonic enhanced-lyrics
serializer (server/subsonic/lyrics.go) resolves cue ends per agent group while
building the response; that is the only legitimate cross-package caller.

Also includes a small no-op robustness tweak in parseLRC: len(times) == 0
instead of times == nil (equivalent here, more idiomatic).

No behavior change.

* test(lyrics): add direct coverage for NormalizeCueEnds

NormalizeCueEnds is exported and carries the most intricate logic in the
normalization cluster (fill-from-next, fill-from-fallback, both clamps, and the
all-or-none clear), but was only exercised transitively. Add a focused spec
covering each branch plus the empty-input and no-mutation guarantees, bringing
the function to 100% coverage.

* test(lyrics): cover legacy getLyrics across formats and sources

Expand the legacy getLyrics e2e coverage from a single embedded-plain case to a
table over all six fixtures: embedded LRC/plain/TTML and sidecar LRC/SRT/YAML.

Each case asserts the v1 plain-text fallback contract — the structured lyric is
flattened to LRC-style plain text with no timing markup leaking through (no LRC
brackets, SRT arrows, or XML tags), regardless of the source format or whether
it is embedded or a sidecar file. This pins the behavior that synced TTML/SRT/
YAML formats degrade gracefully to plain text on the legacy endpoint.

* test(lyrics): cover songLyrics v1 vs v2 with word-level fixtures

Correct and expand the e2e lyrics coverage to match the OpenSubsonic songLyrics
extension contract:

- v1 (getLyricsBySongId, no enhanced): line-level lyrics with no cueLine, kind,
  or agents — even for word-level formats (ELRC, Lyricsfile YAML).
- v2 (getLyricsBySongId?enhanced=true): word-level cueLine surfaces for ELRC and
  YAML sources; kind="main" is set; a line-level source (SRT) still yields no
  cueLine even when enhanced.
- legacy getLyrics (artist/title): the original Subsonic endpoint, flattening any
  format to plain text. A prior commit mislabeled this as the "v1 contract";
  getLyrics predates OpenSubsonic and is unrelated to the extension versions.

Drive these with the public-domain tests/fixtures/lyrics files (the same set the
parser benchmarks use) so the e2e content stays in sync and actually carries the
word-level timing needed to distinguish v1 from v2. The embedded "synced LRC"
fixture is upgraded to ELRC (word-level); track counts are unchanged, so the
rest of the suite is unaffected.

* test(lyrics): parameterize v2 enhanced coverage across all formats

Convert the v2 (enhanced) e2e block from three ad-hoc cases into a DescribeTable
covering all six formats, matching the v1 and legacy tables. Each entry declares
whether the source carries word-level timing: ELRC, TTML, and Lyricsfile YAML
surface a cueLine; LRC, SRT, and plain text do not. All six get kind="main".

Add word-level <span> timing to the first line of the auld-lang-syne.ttml
fixture so TTML exercises the word-level cueLine path (the parser already
supports <span begin/end>, but the fixture was line-level only). The first line
now yields the same five word cues as the ELRC and YAML fixtures, keeping the
table assertions uniform across formats.

* fix(lyrics): honor caller language when Lyricsfile YAML omits it

parseLyricsfile discarded the caller's language argument, so a Lyricsfile YAML
parsed from an embedded tag or plugin response with no metadata.language was
labeled "xxx" even when ParseLyrics was given a language. The SRT and TTML
parsers already use the caller language as their default; fall back to it here
too, preferring the document's own metadata.language when present.

Also reword a misleading TTML comment: isTTMLDocument still runs an XML decode
(it stops at the first element), so the skip avoids the full TTML parse, not the
XML decoder entirely.

* refactor(lyrics): consolidate lyrics parsing functions names

* test(lyrics): drop test-only parse wrappers after parser rename

Commit 48c0173e8 renamed the production parsers to parseTTML/parseSRT, which
collided with the same-named test-only wrappers and broke the model test build
(parseTTML/parseSRT redeclared). Remove the wrappers and call the production
parsers directly with the placeholder language at each test site.

* test(lyrics): complete the truncated enhanced-LRC fixture

The auld-lang-syne.elrc fixture stopped after the first two stanzas (8 lyric
lines) while every other format fixture carries the full 24-line song. Extend it
to all 24 lines with per-word timing so it is a faithful enhanced-LRC sample and
the EnhancedLRC parser benchmark runs on a workload comparable to the others.
The first line's word timings are unchanged, so the e2e cueLine assertions still
hold.
