Previously the filler only flagged albums whose DB thumb_url was empty and, on
apply, only updated that DB thumb_url — so albums whose files had no embedded
art and no cover.jpg (but whose DB row had a URL) were never found, and even
'applying' art never touched the files. That's the reported 'doesn't scan all
albums' gap.
New core.metadata.art_apply (reuses the post-processing standard so the user's
album_art_order is honored):
- album_has_art_on_disk(): cheap-first check — folder cover.jpg/folder.jpg
sidecar, then embedded art in a representative track (FLAC/ID3/MP4/Vorbis).
- apply_art_to_album_files(): embeds via embed_album_art_metadata + writes
cover.jpg via download_cover_art; only ADDS art (never rewrites the user's
tags); read-only/unwritable files are skipped + counted, never crash.
Scan now examines every titled album and flags it when art is missing in the DB
OR on disk. Apply embeds into the album's audio files + writes cover.jpg in
addition to the DB thumbnail (media-server-only albums fall back to DB-only).
Tests cover sidecar/embedded detection, the cheap-first short-circuit, and the
apply orchestration (embeds each file + cover.jpg; read-only failures counted).
The title/artist fallback search took results[0]'s artwork unconditionally, so
a loose full-text match returned the wrong album's cover (the 'new sources give
incorrect art' reports). Now it pulls a few results and only accepts one whose
title matches (subset, to allow Deluxe/Remaster) AND whose artist matches
exactly — the artist being the strong guard against wrong covers. Falls back to
an exact title match when a result carries no artist.
The album's own stored source-id path is unchanged (that id is authoritative).
Tests: wrong-artist rejected, skips wrong result for a matching one, + unit
coverage of the matcher (deluxe/feat/stopwords accepted, wrong artist/title
rejected).
`_create_finding` silently dedup-skipped re-discovered issues but
the caller incremented `findings_created` regardless. So a re-scan
that found the same issues as a prior scan reported 364 findings
in the badge while 0 NEW pending rows hit the db, leaving the
findings tab empty.
`_create_finding` now returns bool (True on insert, False on
dedup-skip / db error). All 16 repair jobs updated to only
increment `findings_created` on True. Added `findings_skipped_dedup`
counter surfaced in scan log: "Done: X scanned, 0 fixed, 0
findings (363 already existed), 0 errors".
Also fixed a missing `job_id` kwarg in album_tag_consistency that
was silently breaking finding creation for that scan.
8 test files had _DummyConfigManager missing get_active_media_server(),
causing failures when pytest ran them before the test file that had it.
Whichever file set sys.modules first won, and the incomplete dummy broke
later tests. Also fix script.js read_text() missing encoding='utf-8'
which failed on non-UTF-8 default locales.
Cover art lookup now honors an explicit prefer_source first,
falls back to the runtime primary metadata source when unset,
and uses the shared source priority for the remaining fallbacks.
