refactor(artwork): migrate readers to storage.MusicFS and add e2e suite (#5379)
* test(artwork): add e2e suite documenting album/disc resolution

Adds core/artwork/e2e/ with a real-tempdir + scanner harness that exercises
artwork resolution end-to-end. Covers album and disc kinds; pending (PIt)
cases document two known bugs in reader_album.go for regression-guard
flipping once they are fixed.

* refactor(artwork): add libraryFS helper to resolve MusicFS for a library

* test(artwork): tighten libraryFS test isolation and add scheme-error case

* test(artwork): update libraryFS test description to match implementation

* refactor(artwork): convert fromExternalFile to use fs.FS

Add a temporary fromExternalFileAbs shim so existing absolute-path callers
still compile; the shim is removed once all readers are migrated.

* refactor(artwork): make fromExternalFileAbs a thin delegator

Introduce a minimal osDirectFS adapter so the shim no longer duplicates
the matching loop. Both will be removed in Task 9.

* refactor(artwork): convert fromTag to taglib.OpenStream over fs.FS

Add a temporary fromTagAbs shim so existing absolute-path callers still
compile; removed in Task 9. Reuses the osDirectFS adapter from Task 2.

* refactor(artwork): defer fs.File close until after taglib reads finish

Mirror the lifetime pattern used by adapters/gotaglib/gotaglib.go:
keep the underlying fs.File open until taglib.File is closed, and
pass WithFilename so format detection doesn't rely on content sniffing.

* docs(artwork): note ffmpeg's path-based API limitation

* refactor(artwork): migrate album reader to MusicFS

- Add libFS (storage.MusicFS) field to albumArtworkReader; resolved
  once at construction time via libraryFS()
- Switch fromCoverArtPriority from abs-path shims to FS-based
  fromTag/fromExternalFile; only fromFFmpegTag retains absolute path
- Build imgFiles as library-relative forward-slash paths in
  loadAlbumFoldersPaths using path.Join(f.Path, f.Name, img)
- Guard embedAbs so that an empty EmbedArtPath never produces a
  non-empty absolute path (prevents accidental ffmpeg invocation)
- Register testfile:// storage scheme in artwork test suite to provide
  an os.DirFS-backed MusicFS without requiring the taglib extractor
- Update test assertions from filepath.FromSlash(abs) to bare
  forward-slash relative strings

* fix(artwork): use path package in compareImageFiles for forward-slash relative paths

* refactor(artwork): migrate disc reader to MusicFS

Replace os.Open absolute-path access with libFS.Open on library-relative
forward-slash paths. Rename discFolders→discFoldersRel, split
firstTrackPath into firstTrackRelPath (for fromTag) and firstTrackAbsPath
(for fromFFmpegTag), and switch path.Dir/Base/Ext for forward-slash safety.

* refactor(artwork): build discFoldersRel directly and guard empty first track

* refactor(artwork): migrate mediafile reader to MusicFS

* refactor(artwork): migrate artist album-art lookup to MusicFS

* refactor(artwork): remove temporary path-based shims

All readers now use the FS-based fromTag and fromExternalFile directly,
so the absolute-path adapters and the osDirectFS helper that backed
them can go away.

* test(artwork): rewrite e2e suite to use storagetest.FakeFS

Switches from real-tempdir + local storage to FakeFS via the storage
registry. Adds a proper multi-disc scenario using the disc tag, which
previously required curated MP3 fixtures we did not have.

* test(artwork): use maps.Copy in trackFile tag merge

Lint cleanup: replace the manual map-copy loop flagged by mapsloop.

* test(artwork): reuse tests.MockFFmpeg in e2e harness

Replace the hand-rolled noopFFmpeg stub with tests.NewMockFFmpeg, which
already satisfies the full ffmpeg.FFmpeg interface and won't drift when
new methods are added. Also tie imageBytes to imageFile so they cannot
silently disagree on the on-disk encoding.

* test(artwork): add e2e scenarios from artwork documentation

Covers the behaviors documented at
https://www.navidrome.org/docs/usage/library/artwork/:

- Album: folder.*/front.* fallbacks and priority order with cover.*.
- Disc: cd*.* match, cover.* inside disc folder, DiscArtPriority="" skip
  path, the documented multi-disc layout, and the discsubtitle keyword.
- MediaFile: disc-level fallback for multi-disc tracks and album-level
  fallback for single-disc tracks (doc section "MediaFiles" items 2-3).
- Artist: album/artist.* lookup via libFS (passes). The artist-folder
  branch is XIt-marked because fromArtistFolder still calls os.DirFS
  directly on an absolute path and can't read from a FakeFS-backed
  library — migrating that to storage.MusicFS is a follow-up.

* refactor(artwork): scope artist folder traversal to library root

Route fromArtistFolder reads through storage.MusicFS and bound the
parent-directory walk at the library root. This keeps artwork
resolution scoped to the configured library and unblocks FakeFS-backed
e2e scenarios that depend on the artist folder.

Also consolidate the libraryFS + core.AbsolutePath pairing (used by
three readers) into a single libraryFSAndRoot helper.

* test(artwork): add ASCII file-tree diagrams to e2e scenarios

Each It/PIt block now shows the on-disk layout it exercises, with
arrows indicating which file wins (or should win, for the known-bug
PIt cases). Makes scenarios readable at a glance without having to
parse the MapFS map.

* test(artwork): cover additional edge cases in e2e suite

Add high-value scenarios uncovered by the existing specs:

- Album: three-way basename tie (unsuffixed wins), unknown pattern in
  CoverArtPriority is skipped, embedded-first with no embedded art
  falls through.
- Disc: discsubtitle with no matching image falls through.
- Artist: ArtistArtPriority can reach images via album/<pattern>.
- Playlist: generates a 2x2 tiled cover from album art when the playlist
  has no uploaded/sidecar/external image.

New helper realPNG() produces real taglib/image-decodable bytes so the
tiled-cover test can exercise the generator's decode + compose path.

* test(ffmpeg): simplify animated WebP encoder check by removing context parameter

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

* fix(artwork): normalize rel path for fs.Glob on Windows

filepath.Rel returns backslash-separated paths on Windows, but fs.Glob
and path.Join require forward slashes. Convert with filepath.ToSlash
after computing the relative path and use path.Dir for the parent walk
so the artist-folder lookup works cross-platform.

* fix(ffmpeg): retry animated WebP probe on transient failure

The probe previously used the caller's request context inside sync.Once,
so a single cancelled first request would permanently disable animated
WebP for the rest of the process. Switch to a mutex + probed flag, use
a fresh background context with its own timeout, and only cache the
result when the probe actually succeeds.

* test(ffmpeg): reset ffOnce so ConvertAnimatedImage test is order-independent

The ConvertAnimatedImage stand-in test sets ffmpegPath directly but
does not reset ffOnce. If ffmpegCmd() has not been called earlier in
the test process, the next call inside hasAnimatedWebPEncoder runs
ffOnce.Do and re-resolves the real ffmpeg binary, overwriting the
stand-in and breaking the test. Reset ffOnce and conf.Server.FFmpegPath
alongside the other globals to pin resolution to the stand-in.

* test(artwork): unblock Windows CI — forward-slash fs paths and suite-level DB lifetime

The internal artwork test planted a Windows absolute path (backslashes) into
Folder.Path and then fed it through libFS.Open, which fs.ValidPath rejects.
Rooting the testfile library at the temp dir directly and using
filepath.ToSlash keeps the path model library-relative and forward-slash,
matching production.

The e2e suite opened a per-spec DB in a per-spec TempDir, but the go-sqlite3
singleton kept the file open across specs. Ginkgo's per-spec TempDir cleanup
then tried to unlink a file still held by that handle — fine on POSIX, fails
on Windows. Moving the DB to a suite-level tempdir and closing it in
AfterSuite avoids the race.

* test(artwork): keep Windows drive letters intact in testfile library URLs

url.Parse on `testfile://C:/path` reads `C` as the host and the path loses
the drive letter, so Windows libFS lookups go to `/path` and fail.
testFileLibPath now prepends a `/` when the OS path has no leading slash,
and the testfile constructor strips that extra slash back off before
handing the path to os.Stat / os.DirFS.

* refactor(artwork): consolidate libFS + root into libraryView helper

Collapses the per-reader libFS/libPath/rootFolder/firstTrackAbsPath fields
into a single libraryView{FS, absRoot} with an Abs(rel) method. Also folds
the two library lookups (ds.Library.Get + core.AbsolutePath) into one, and
uses mf.Path directly instead of stripping libRoot off an absolute path.

* refactor(ffmpeg): replace hasAnimatedWebPEncoder with encoderProbe for state management

* fix: escape artist folder names in artwork glob

Escape glob metacharacters in the library-relative artist folder path before composing the fs.Glob pattern for artist image lookup. This preserves literal folder names such as Artist [Live] while keeping the configured filename pattern behavior unchanged, and adds a regression test for bracketed artist folders.

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

* fix(artwork): correct test path assertions after MusicFS migration

Source functions (fromTag, fromExternalFile) now return forward-slash
fs.FS-relative paths, so test assertions should compare against plain
forward-slash strings, not filepath.FromSlash(). The artistArtPriority
test needs filepath.FromSlash() on the suffix because findImageInFolder
returns OS-native absolute paths via filepath.Join.

* fix(artwork): normalize path separators in artistArtPriority assertion

The two table entries exercise different code paths: entry 1 goes through
fromArtistFolder (returns OS-native paths via filepath.Join), while entry 2
goes through fromExternalFile (returns forward-slash fs.FS paths). Using
filepath.FromSlash on the expected value only works for entry 1.

Normalize the actual path to forward slashes with filepath.ToSlash so a
single HaveSuffix assertion works for both code paths on all platforms.

fix(artwork): return correct timestamp when disc or album coverart changes (#5378)
* fix(artwork): return imagesUpdatedAt in LastUpdated when cover art changes

When cover art (cover.jpg) is updated in an album folder, the HTTP
Last-Modified header was incorrectly returning album.UpdatedAt (which
only tracks media file changes) instead of imagesUpdatedAt (which
tracks cover art changes).

This caused browsers to use their cached cover art because the
Last-Modified header didn't change, even though the actual cover art
image data was new (due to cache key changing based on imagesUpdatedAt).

The fix ensures LastUpdated() returns a.lastUpdate (which is the max of
album.UpdatedAt and imagesUpdatedAt) instead of always returning
album.UpdatedAt.

Fixes navidrome/navidrome#5377

* refactor tests

* fix(artwork): return imagesUpdatedAt in disc LastUpdated

The discArtworkReader had the same bug as albumArtworkReader (fixed in
9a741859f): LastUpdated() returned album.UpdatedAt while Key() used the
max of album.UpdatedAt and ImagesUpdatedAt. This mismatch caused browsers
to keep stale disc cover art in cache when only the image file changed.

Also strengthen the album LastUpdated tests and add matching tests for
the disc reader. The tests use DescribeTable and were verified to fail
when the fix is reverted.

fix(artwork): allow shared disc art from unnumbered filenames in single-folder albums (#5344)
* test(artwork): expect shared disc art for unnumbered filenames in single-folder albums

* fix(artwork): match unnumbered disc art for every disc in single-folder albums

* test(artwork): verify shared disc art resolves for every disc number

* test(artwork): regression guard for numbered disc filter with mixed filenames

* test(artwork): verify DiscArtPriority order decides numbered vs shared disc art

* test(artwork): strengthen regression guard to exercise both disc art branches

* refactor(artwork): simplify disc art matching and drop redundant comments

- Lowercase the pattern and filename once in fromExternalFile and pass
  lowered values into extractDiscNumber, eliminating the duplicate
  strings.ToLower calls inside that helper.
- Drop narrating comments in reader_disc.go and reader_disc_test.go that
  duplicated information already conveyed by nearby code or doc comments.

* fix(artwork): prefer numbered disc art over shared fallback within a pattern

Review feedback: with files [disc.jpg, disc1.jpg, disc2.jpg] in a single
folder, the previous single-folder fall-through returned the first match
in imgFiles order. Because compareImageFiles sorts 'disc' before 'disc1'
and 'disc2', disc.jpg would mask the per-disc numbered files for every
disc, regressing the behavior from before the shared-disc-art change.

Within a single pattern the loop now records the first viable unnumbered
candidate as a fallback and keeps scanning for a numbered match equal to
the target disc. Numbered matches still win immediately; the shared file
is only returned when no numbered match for the target disc exists.

Also drops the redundant strings.ToLower(pattern) at the top of
fromExternalFile; fromDiscArtPriority already lowercases the whole
priority string before splitting, so the function contract is now
'pattern must be lowercase' (documented on the function).

* refactor(artwork): trim disc art matching comments and table-drive tests

Doc comment on fromExternalFile is trimmed to the one non-obvious
contract (caller must pre-lowercase the pattern) plus the headline
behavior; the bulleted restatement of the branch logic went away.
Two inline comments that narrated what the code already shows are
also gone.

Hoisting a `hasWildcard := strings.ContainsRune(pattern, '*')` check
out of the loop avoids per-iteration extractDiscNumber calls for
literal patterns (e.g. `shellac.png`) and lets the loop break as
soon as a viable fallback is found, since literal patterns can never
be beaten by a numbered match. Wildcard patterns keep the original
scan-to-end-for-numbered-match behavior.

The two regression tests added in the previous commit were
structurally identical apart from discNumber/expected, so they are
collapsed into a DescribeTable with two entries — matching the
existing table style used for extractDiscNumber tests in the same
file.

* fix(artwork): support '?' and '[...]' wildcards in disc art patterns

filepath.Match understands three glob metacharacters ('*', '?', '[')
but extractDiscNumber only looked for '*'. A pattern like 'disc?.jpg'
or 'cd[12].jpg' would therefore be treated as unnumbered, and every
disc of a multi-disc album would resolve to the same (first-sorted)
file instead of the per-disc numbered art.

extractDiscNumber now finds the literal prefix of the pattern by
scanning for the first '*', '?', or '[' (via strings.IndexAny),
strips it from the filename, and parses the leading digits that
follow. The standalone filepath.Match check is dropped; HasPrefix
plus the leading-digits requirement is enough to reject non-matches,
and the caller already verifies the glob match before calling.

fromExternalFile's literal-pattern optimization is widened
correspondingly: a pattern is treated as literal only when it
contains none of '*', '?', '['. Any wildcard form now keeps the
scan-to-end behavior so a numbered match can beat a fallback.

Adds table entries for both the extractDiscNumber parser and the
fromExternalFile higher-level behavior, covering '?' and '[...]'
patterns as well as a literal-pattern baseline.

* refactor(artwork): tidy extractDiscNumber after glob-wildcard support

- Name the '*?[' charset as globMetaChars, used by both extractDiscNumber
  and fromExternalFile so the two call sites can't drift.
- Trim the extractDiscNumber doc comment: keep the non-obvious caller
  contract, drop the algorithm narration.
- Replace the byte-slice digit accumulator with a direct filename slice
  fed to strconv.Atoi.
- Rename the four new non-'*' wildcard Entry descriptions so they read
  like the existing extractDiscNumber table ('pattern, target → expected')
  instead of the ambiguous 'disc 1' shorthand.

* fix(artwork): retry remaining fallbacks when the first one fails to open

Review feedback: the previous shape remembered only the first unnumbered
candidate and fell through to a generic error if os.Open failed on it,
even though other matching unnumbered files in imgFiles could have
succeeded. The pre-PR code was more resilient because it looped and
continued on open failure.

fromExternalFile now collects every viable unnumbered candidate into a
slice during the scan, then tries them in order after the loop, mirroring
the pre-PR retry-on-open-failure behavior. Numbered matches still return
immediately on first success and skip the candidate list entirely — an
open failure on a numbered match means no other file has that number
anyway.

Also:
- globMetaChars doc comment now notes that '\' escape is intentionally
  excluded (filepath.Match supports it but treating it as a metachar here
  would misalign extractDiscNumber's literal-prefix extraction with no
  benefit for realistic config patterns).
- The 'cover.jpg doesn't match disc*.*' Entry in the extractDiscNumber
  table is renamed to 'cover.jpg with disc*.* (no prefix match)' to
  reflect that the test now exercises the HasPrefix defensive guard,
  not the removed internal filepath.Match check.

Regression test added: a single-folder album with a deleted first
candidate file resolves to the second candidate.

* fix(artwork): scan all literal-pattern matches so fallback retry works

Review feedback: the 'break on first literal match' optimization
assumed only one file in imgFiles could match a literal basename,
but filepath.Match compares basenames only — multiple folders can
contribute files with the same basename, and the fallback-list retry
in 5d79f751c is defeated if the loop breaks after recording just
the first one.

Removing the break makes literal and wildcard patterns follow the
same scan-to-end path, preserving the retry-on-open-failure
resilience regained in 5d79f751c. The efficiency cost is negligible
— imgFiles is 5-20 entries per album and this is a cache-miss path.

feat(artwork): add per-disc cover art support (#5182)
* feat(artwork): add KindDiscArtwork and ParseDiscArtworkID

Add new disc artwork kind with 'dc' prefix for per-disc cover art
support. The composite ID format is albumID:discNumber, parsed by
the new ParseDiscArtworkID helper.

* feat(conf): add DiscArtPriority configuration option

Default: 'disc*.*, cd*.*, embedded'. Controls how per-disc cover
art is resolved, following the same pattern as CoverArtPriority
and ArtistArtPriority.

* feat(artwork): implement extractDiscNumber helper

Extracts disc number from filenames based on glob patterns by
parsing leading digits from the wildcard-matched portion.
Used for matching disc-specific artwork files like disc1.jpg.

* feat(artwork): implement fromDiscExternalFile source function

Disc-aware variant of fromExternalFile that filters image files
by disc number (extracted from filename) or folder association
(for multi-folder albums).

* feat(artwork): implement discArtworkReader

Resolves disc artwork using DiscArtPriority config patterns.
Supports glob patterns with disc number extraction, embedded
images from first track, and falls back to album cover art.
Handles both multi-folder and single-folder multi-disc albums.

* feat(artwork): register disc artwork reader in dispatcher

Add KindDiscArtwork case to getArtworkReader switch, routing
disc artwork requests to the new discArtworkReader.

* feat(subsonic): add CoverArt field to DiscTitle response

Implements OpenSubsonic PR #220: optional cover art ID in
DiscTitle responses for per-disc artwork support.

* feat(subsonic): populate CoverArt in DiscTitle responses

Each DiscTitle now includes a disc artwork ID (dc-albumID:discNum)
that clients can use with getCoverArt to retrieve per-disc artwork.

* style: fix file permission in test to satisfy gosec

* feat(ui): add disc cover art display and lightbox functionality

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

* refactor: simplify disc artwork code

- Add DiscArtworkID constructor to encapsulate the "albumID:discNumber"
  format in one place
- Convert fromDiscExternalFile to a method on discArtworkReader,
  reducing parameter count from 6 to 2
- Remove unused rootFolder field from discArtworkReader

* style: fix prettier formatting in subsonic index

* style(ui): move cursor style to makeStyles in SongDatagrid

* feat(artwork): add discsubtitle option to DiscArtPriority

Allow matching disc cover art by the disc's subtitle/name.
When the "discsubtitle" keyword is in the priority list, image files
whose stem matches the disc subtitle (case-insensitive) are used.
This is useful for box sets with named discs (e.g., "The Blue Disc.jpg").
