serveEntity reads persisted item_artwork by id, bypassing the library and private-
playlist filters that the legacy entity-load applied. On the authenticated Subsonic
path a user could fetch artwork for an inaccessible album or someone else's private
playlist by guessing an id. getCoverArt now resolves the underlying entity through
the request-scoped (filtered) repositories and serves the placeholder when it is not
visible, so existence isn't leaked and the always-an-image invariant holds. The
public share (JWT-authorized) and Jellyfin (admin) paths are intentionally untouched.
* 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.
* 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

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

Expand backend lyrics support with richer sidecar formats and upgrade the
OpenSubsonic songLyrics implementation to the version 2 structured karaoke
contract, while preserving version 1 behavior by default.
Sidecar formats and parsing:
- Add a TTML parser (core/lyrics/ttml.go): clock time, offset time, bare
decimal seconds, nested timing contexts, and token-level <span> timing for
word/syllable karaoke. Parses Apple Music-style metadata tracks (translation
and pronunciation/transliteration) and agent metadata into per-track agents[]
plus per-cue-line agentId. Hydrates missing line timing from cue timing.
- Add an SRT parser (core/lyrics/srt.go).
- Add a LRCLIB Lyricsfile (.yaml/.yml) parser (model/lyricsfile.go): maps
per-word lines[].words[] to cues with inclusive UTF-8 byte offsets and
attributes overlapping lines to synthetic voice agents so parallel vocals
split correctly in the enhanced response.
- Extend LRC parsing for Enhanced LRC inline <mm:ss.xx> word-timing markers.
- Add UTF-8 BOM and UTF-16 LE support for TTML/LRC sidecars.
- Parse the above formats from embedded tags as well as sidecar files.
Source resolution:
- Default lyricspriority is now
".ttml,.yaml,.yml,.elrc,.lrc,.srt,.txt,embedded" so the new formats are
discoverable without manual configuration.
- Preserve configured source priority across duplicate media-file candidates
instead of only checking the first DB match, so higher-priority sidecar
lyrics on older duplicates can still win.
- Raise the embedded-lyrics tag maxLength to 1 MB to fit word-timed
TTML/Enhanced-LRC karaoke for a full song.
OpenSubsonic songLyrics v2:
- Advertise songLyrics versions [1, 2].
- With enhanced=true, getLyricsBySongId may return structuredLyrics.kind
(main/translation/pronunciation), cueLine[] line-level karaoke groupings,
cueLine.cue[] timed words/syllables with required UTF-8 byteStart/byteEnd,
reusable structuredLyrics.agents[], and cueLine.agentId references.
- Without enhanced=true, the response stays v1-compatible: no kind, no cueLine,
no agents, no non-main tracks; the existing line[] payload is always
populated so legacy clients keep working.
Contract details:
- cueLine is emitted only for synced lyrics with cue data.
- Within a cueLine, cue.end is normalized all-or-none and overlaps are removed;
overlaps across separate cueLines remain valid for parallel vocal layers.
- Missing cue end-times are filled from the next cue or the parent line.
- When cueLines share an index, the one whose agent has role "main" is first.
- LyricCue.Value is serialized as XML chardata; cues with nil start are skipped
rather than serialized as 0.
Refactoring:
- Move pure format parsers into model/ (lyrics.go, lyrics_ttml.go,
lyrics_srt.go, lyrics_embedded.go, lyricsfile.go) and extract Subsonic
response building into server/subsonic/lyrics.go.
- Centralize lyric-kind constants and add Lyrics.EffectiveKind/IsMainKind.
- Add gg.Clone helper.

* fix(server): prevent artwork throttle token starvation on slow clients
Replace Chi's ThrottleBacklog middleware for artwork endpoints with a
custom RequestThrottle that releases processing tokens before writing
the HTTP response. Previously, a slow or stalled client could hold a
throttle token indefinitely during io.Copy, exhausting all 2-4 slots
and blocking artwork requests for all users (reported after 15+ days
uptime).
The new approach buffers artwork into memory while holding the token,
releases it immediately, then writes the buffered response. A 30-second
per-request write deadline (SetWriteTimeout) prevents stalled writes
from blocking indefinitely. Throttle exhaustion is now logged with
context for operator visibility.
* refactor(server): simplify throttle to middleware with same API as Chi
Restructure RequestThrottle from a DI-injected type into a drop-in
middleware function with the same signature as Chi's ThrottleBacklog.
Handlers are reverted to their original simple form (no throttle
awareness), and the middleware is applied at route definition time
just like before. This eliminates the DI dependency, removes the
artworkThrottle field from both Router structs, and consolidates
SetWriteTimeout into the throttle file. When limit <= 0, the
middleware returns a passthrough so callers don't need a guard.
Signed-off-by: Deluan <deluan@navidrome.org>
* feat(server): add opt-out flag for buffered artwork throttle
Add DevArtworkThrottleBuffered config (default true) that controls
whether the new buffered ThrottleBacklog middleware is used. When set
to false, it falls back to Chi's original middleware, giving users a
safety valve in case the buffered implementation causes issues.
Signed-off-by: Deluan <deluan@navidrome.org>
* test(server): clean up throttle tests for clarity and speed
Consolidate duplicate router setup into runTwoRequests() and
slowClientTest() helpers. Replace time.Sleep-based token holding with
channel synchronization, reducing suite time from ~7s to ~1.5s.
Remove redundant test, fix duplicate comment block, and add comment
explaining why slowTestWriter can't embed httptest.ResponseRecorder.
* fix: release artwork throttle tokens on panic
Defer the buffered artwork throttle release inside the handler closure so tokens are returned even when a downstream handler panics before response flushing. Document that the middleware buffers full responses in memory and add a regression test covering recovery after a panic.
* fix: align buffered throttle response behavior
Keep only the first status code written to the buffered artwork throttle response writer so it matches net/http semantics. Strengthen the opt-out test to verify DevArtworkThrottleBuffered=false uses Chi's original slow-client behavior instead of only checking shared 429 handling.
* refactor(server): remove setWriteTimeout from throttle middleware
SetWriteDeadline only constrains the server's Write syscall, not how
fast the client reads from the TCP buffer. For artwork-sized responses
(up to ~500KB), the kernel accepts the entire write immediately even
over real network interfaces due to TCP buffer auto-tuning. Verified
by testing with a stalled client over both loopback and en0 — the
deadline never triggers. The actual protection comes from buffering +
early token release, which is already in place.

* feat(subsonic): add getSonicSimilarTracks and findSonicPath handlers
Add two new Subsonic API handlers for the sonicSimilarity OpenSubsonic extension: GetSonicSimilarTracks returns similarity-scored tracks similar to a given song, and FindSonicPath returns a path of tracks connecting two songs. Both handlers delegate to the sonic core service and map results to SonicMatch response types.
* feat(subsonic): advertise sonicSimilarity extension when plugin available
Update GetOpenSubsonicExtensions to conditionally include the sonicSimilarity extension only when a sonic similarity plugin provider is available. The nil guard ensures backward compatibility with tests that pass nil for the sonic field. Also update the existing test to pass the new nil parameter.
* feat(subsonic): wire sonic similarity service into router
Add the sonic.Sonic service to the Router struct and New() constructor, register the getSonicSimilarTracks and findSonicPath routes, and wire sonic.New and its PluginLoader binding into the Wire dependency injection graph. Update all existing test call sites to pass the new nil parameter. Regenerate wire_gen.go.
* fix(e2e): add sonic parameter to subsonic.New call in e2e tests
* test(subsonic): add sonicSimilarity extension advertisement tests
Restructures the GetOpenSubsonicExtensions test into two contexts: one verifying the baseline 5 extensions are returned when no sonic similarity plugin is configured, and one verifying that the sonicSimilarity extension is advertised (making 6 total) when a plugin loader reports an available provider. Adds a mockSonicPluginLoader to satisfy the sonic.PluginLoader interface without requiring a real plugin.
* feat(subsonic): add nil guard and e2e tests for sonic similarity endpoints
Handlers return ErrorDataNotFound when no sonic service is configured,
preventing nil panics. E2e tests verify both endpoints return proper
error responses when no plugin is available.
* fix(subsonic): return HTTP 404 when no sonic similarity plugin available
Endpoints are always registered but return 404 when no provider is
available, rather than a subsonic error code 70.
* refactor: clean up sonic similarity code after review
Extract shared helpers to reduce duplication across the sonic similarity
implementation: loadAllMatches in matcher consolidates the 4-phase
matching pipeline, songRefToAgentSong eliminates per-iteration slice
allocation in the adapter, sonicMatchResponse deduplicates response
building in handlers, and a package-level constant replaces raw
capability name strings in core/sonic.
* fix empty response shapes

* test(plugins): add testdata plugin and e2e tests for sonic similarity
Add a test-sonic-similarity WASM plugin that implements both
GetSonicSimilarTracks and FindSonicPath via the generated sonicsimilarity
PDK. The plugin returns deterministic test data with decreasing similarity
scores and supports error injection via config. Adapter tests verify the
full round-trip through the WASM plugin including error handling. Also
includes regenerated PDK code from make gen.

* fix: address PR review feedback for sonic similarity
Fix incorrect field names in README documentation ({from, to} →
{startSong, endSong}) and remove unnecessary XML serialization test
from e2e suite since OpenSubsonic endpoints only use JSON.
* refactor: rename Matcher methods for conciseness
Rename MatchSongsToLibrary to MatchSongs and MatchSongsToLibraryMap to
MatchSongsIndexed. The Matcher receiver already establishes the "to
library" context, making that suffix redundant, and "Indexed" better
describes the intent (preserving input ordering) than "Map" which
describes the data structure.

fix bpsToKbps integer truncation with rounding, add "pcm" to

* fix: small issues
Updated mock AAC transcoding command to use the new default (ipod with
fragmented MP4) matching the migration, ensuring tests exercise the same
buildDynamicArgs code path as production. Improved archiver test mock to
match on the whole StreamRequest struct instead of decomposing fields,
making it resilient to future field additions. Added named constants for
JWT claim keys in the transcode token and wrapped ParseTranscodeParams
errors with ErrTokenInvalid for consistency. Documented the IsLossless
BitDepth fallback heuristic as temporary until Codec column is populated.

* fix(transcoding): adapt transcode claims to struct-based auth.Claims
Updated transcode token handling to use the struct-based auth.Claims
introduced on master, replacing the previous map[string]any approach.
Extended auth.Claims with transcoding-specific fields (MediaID, DirectPlay,
UpdatedAt, Channels, SampleRate, BitDepth) and added float64 fallback in
ClaimsFromToken for numeric claims that lose their Go type during JWT
string serialization. Also added the missing lyrics parameter to all
subsonic.New() calls in test files.
* feat(model): add ProbeData field and UpdateProbeData repository method
Add probe_data TEXT column to media_file for caching ffprobe results.
Add UpdateProbeData to MediaFileRepository interface and implementations.
Use hash:"ignore" tag so probe data doesn't affect MediaFile fingerprints.
* feat(ffmpeg): add ProbeAudioStream for authoritative audio metadata
Add ProbeAudioStream to FFmpeg interface, using ffprobe to extract
codec, profile, bitrate, sample rate, bit depth, and channels.
Parse bits_per_raw_sample as fallback for FLAC/ALAC bit depth.
Normalize "unknown" profile to empty string.
All parseProbeOutput tests use real ffprobe JSON from actual files.
* feat(transcoding): integrate ffprobe into transcode decisions
Add ensureProbed to probe media files on first transcode decision,
caching results in probe_data. Build SourceStream from probe data
with fallback to tag-based metadata.
Refactor decision logic to pass StreamDetails instead of MediaFile,
enabling codec profile limitations (e.g., audioProfile) to use
probe data. Add normalizeProbeCodec to map ffprobe codec names
(dsd_lsbf_planar, pcm_s16le) to internal names (dsd, pcm).
NewDecider now accepts ffmpeg.FFmpeg; wire_gen.go regenerated.
* feat(transcoding): add DevEnableMediaFileProbe config flag
Add DevEnableMediaFileProbe (default true) to allow disabling ffprobe-
based media file probing as a safety fallback. When disabled, the
decider uses tag-based metadata from the scanner instead.
* test(transcode): add ensureProbed unit tests
Test probing when ProbeData is empty, skipping when already set,
error propagation from ffprobe, and DevEnableMediaFileProbe flag.
* refactor(ffmpeg): use command constant and select_streams for ProbeAudioStream
Move ffprobe arguments to a probeAudioStreamCmd constant, following the
same pattern as extractImageCmd and probeCmd. Add -select_streams a:0 to
only probe the first audio stream, avoiding unnecessary parsing of video
and artwork streams. Derive the ffprobe binary path safely using
filepath.Dir/Base instead of replacing within the full path string.
* refactor(transcode): decouple transcode token claims from auth.Claims
Remove six transcode-specific fields (MediaID, DirectPlay, UpdatedAt,
Channels, SampleRate, BitDepth) from auth.Claims, which is shared with
session and share tokens. Transcode tokens are signed parameter-passing
tokens, not authentication tokens, so coupling them to auth created
misleading dependencies.
The transcode package now owns its own JWT claim serialization via
Decision.toClaimsMap() and paramsFromToken(), using generic
auth.EncodeToken/DecodeAndVerifyToken wrappers that keep TokenAuth
encapsulated. Wire format (JWT claim keys) is unchanged, so in-flight
tokens remain compatible.

* refactor(transcode): simplify code after review
Extract getIntClaim helper to eliminate repeated int/int64/float64 JWT
claim extraction pattern in paramsFromToken and ClaimsFromToken. Rewrite
checkIntLimitation as a one-liner delegating to applyIntLimitation.
Return probe result from ensureProbed to avoid redundant JSON round-trip.
Extract toResponseStreamDetails helper and mediaTypeSong constant in
the API layer, and use transcode.ProtocolHTTP constant instead of
hardcoded string.

* fix(transcode): improve code review findings across transcode implementation
- Fix parseProbeData to return nil on JSON unmarshal failure instead of
a zero-valued struct, preventing silent degradation of source stream details
- Use probe-resolved codec for lossless detection in buildSourceStream
instead of the potentially stale scanner data
- Remove MediaFile.IsLossless() (dead code) and consolidate lossless
detection in isLosslessFormat(), using codec name only — bit depth is
not reliable since lossy codecs like ADPCM report non-zero values
- Add "wavpack" to lossless codec list (ffprobe codec_name for WavPack)
- Guard bpsToKbps against negative input values
- Fix misleading comment in buildTemplateArgs about conditional injection
- Avoid leaking internal error details in Subsonic API responses
- Add missing test for ErrNotFound branch in GetTranscodeDecision

* feat(transcode): implement server-side transcoding override for player formats
Signed-off-by: Deluan <deluan@navidrome.org>
* fix(transcode): honor bit depth and channel constraints in transcoding selection
selectTranscodingOptions only checked sample rate when deciding whether
same-format transcoding was needed, ignoring requested bit depth and
channel reductions. This caused the streamer to return raw audio when
the transcode decision requested downmix or bit-depth conversion.
* refactor(transcode): unify streaming decision engine via MakeDecision
Move transcoding decision-making out of mediaStreamer and into the
subsonic Stream/Download handlers, using transcode.Decider.MakeDecision
as the single decision engine. This eliminates selectTranscodingOptions
and the mismatch between decision and streaming code paths (decision
used LookupTranscodeCommand with built-in fallbacks, while streaming
used FindByFormat which only checked the DB).
- Add DecisionOptions with SkipProbe to MakeDecision so the legacy
streaming path never calls ffprobe
- Add buildLegacyClientInfo to translate legacy stream params (format,
maxBitRate, DefaultDownsamplingFormat) into a synthetic ClientInfo
- Add resolveStreamRequest on the subsonic Router to resolve legacy
params into a fully specified StreamRequest via MakeDecision
- Simplify DoStream to a dumb executor that receives pre-resolved params
- Remove selectTranscodingOptions entirely

* refactor(transcode): move MediaStreamer into core/transcode and unify StreamRequest
Moved MediaStreamer, Stream, TranscodingCache and related types from
core/media_streamer.go into core/transcode/, eliminating the duplicate
StreamRequest type. The transcode.StreamRequest now carries all fields
(ID, Format, BitRate, SampleRate, BitDepth, Channels, Offset) and
ResolveStream returns a fully-populated value, removing manual field
copying at every call site. Also moved buildLegacyClientInfo into the
transcode package alongside ResolveStream, and unexported
ParseTranscodeParams since it was only used internally by
ValidateTranscodeParams.
* refactor(transcode): rename Decider methods and unexport Params type
Rename ResolveStream → ResolveRequest and ValidateTranscodeParams →
ResolveRequestFromToken for clarity and consistency. The new
ResolveRequestFromToken returns a StreamRequest directly (instead of
the intermediate Params type), eliminating manual Params→StreamRequest
conversion in callers. Unexport Params to params since it is now only
used internally for JWT token parsing.
* test(transcode): remove redundant tests and use constants
Remove tests that duplicate coverage from integration-level tests
(toClaimsMap, paramsFromToken round-trips, applyServerOverride direct
call, duplicate 410 handler test). Replace raw "http" strings with
ProtocolHTTP constant. Consolidate lossy -sample_fmt tests into
DescribeTable.
* refactor(transcode): split oversized files into focused modules
Split transcode.go and transcode_test.go into focused files by concern:
- decider.go: decision engine (MakeDecision, direct play/transcode evaluation, probe)
- token.go: JWT token encode/decode (params, toClaimsMap, paramsFromToken, CreateTranscodeParams, ResolveRequestFromToken)
- legacy_client.go: legacy Subsonic bridge (buildLegacyClientInfo, ResolveRequest)
- codec_test.go: isLosslessFormat and normalizeProbeCodec tests
- token_test.go: token round-trip and ResolveRequestFromToken tests
Moved the Decider interface from types.go to decider.go to keep it near
its implementation, and cleaned up types.go to contain only pure type
definitions and constants. No public API changes.

* feat(plugins): add lyrics provider plugin capability
Refactor the lyrics system from a static function to an interface-based
service that supports WASM plugin providers. Plugins listed in the
LyricsPriority config (alongside "embedded" and file extensions) are
now resolved through the plugin system.
Includes capability definition, Go/Rust PDK, adapter, Wire integration,

* test(plugins): add lyrics capability integration test with test plugin
* fix(plugins): default lyrics language to 'xxx' when plugin omits it
Per the OpenSubsonic spec, the server must return 'und' or 'xxx' when
the lyrics language is unknown. The lyrics plugin adapter was passing
an empty string through when a plugin didn't provide a language value.
This defaults the language to 'xxx', consistent with all other callers
