The library quality scanner judged quality by FILE EXTENSION only
(get_quality_tier_from_extension) and read the legacy v2 `qualities` dict —
so every FLAC was "lossless tier 1" regardless of bit depth / sample rate. It
could never flag a 16-bit FLAC as upgradeable under a 24-bit profile, and it
ignored the v3 ranked_targets entirely. Completely inconsistent with the
download guard.
Now both share one core:
- selection.targets_from_profile(profile) — single profile→targets conversion
(v2→v3 migration), reused by load_profile_targets.
- selection.quality_meets_profile(aq, targets) — strict: meets iff the real
measured quality satisfies a ranked target (fallback ignored — it's a
download concession, not a definition of "good enough").
- guards.check_quality_target refactored to use both.
- quality_scanner probes real quality (probe_audio_quality) and checks against
the v3 targets via quality_meets_profile. Extension tier kept only as a
fallback label when a file can't be probed.
Result: the scan flags exactly what the download gate would reject — 16-bit
when you want 24-bit, wrong sample rate, MP3 when you want FLAC.

The audiophile preset (fallback_enabled=False) still shipped a "FLAC 16-bit"
target in its ladder, so 16-bit FLAC matched and imported even though the name
implies hi-res-only. Split the ladder: audiophile now uses a strict 24-bit FLAC
list; balanced keeps 24-bit + 16-bit + MP3. Gives users a one-click strict
"24-bit only" profile that actually rejects 16-bit/lossy.
Not a matches_target bug — that correctly rejects 16-bit vs a 24-bit target;
the leak was the preset's target LIST including 16-bit (+ fallback accepting
off-list lossy like MP3-128).

Three fixes from on-device testing of best-quality mode:
1. clear_completed_local no longer prunes terminal tasks that belong to a
STILL-ACTIVE batch (one with non-terminal work remaining). The 5-min
"Clean Completed Downloads" automation was yanking completed/failed/
unverified rows out of download_tasks mid-run — and failed/cancelled
aren't in library_history — so they only reappeared after the batch
ended. Now the whole active batch stays intact until it finishes.
2. search_all_sources runs every source CONCURRENTLY (asyncio.gather)
instead of sequentially, so the pool waits only for the slowest source
(e.g. usenet/Prowlarr) in parallel rather than summing all latencies.
3. The pool log now reports per-source contribution counts
(e.g. "usenet=0, hifi=11, soulseek=1") instead of just echoing the
chain, so a release-level source that returns nothing for a track-title
query is visible rather than appearing to have been searched.

Adds an opt-in search strategy toggle in the Quality Profile:
- priority (default): unchanged — first source in the hybrid chain that
meets a quality target wins.
- best_quality: pool candidates from EVERY source per query and download
them best→worst by actual audio quality; source order only breaks ties.
Implementation reuses existing plumbing so the retry system is untouched:
- engine.search_all_sources pools raw tracks across all configured,
non-exhausted sources (no first-source short-circuit).
- candidates.order_candidates: new quality_first sort path — profile
quality rank dominates, confidence/peer signals break ties. Priority
path is byte-for-byte unchanged (regression-locked by tests).
- task_worker passes quality_first + targets through; skips the redundant
hybrid-fallback block in best-quality mode (pool already covered it).
- Per-source retry budgets unchanged: a source that spends its budget is
added to exhausted_download_sources and thus dropped from the whole
pool. Independent of post_processing.retry_exhaustive.
- Query generator NOT touched.
Also clarifies the "Allow fallback" setting wording: it accepts OFF-LIST
quality as a last resort (not "walk down my list"), and notes that
lossy_copy.downsample_hires also bypasses the quality gate — the cause of
16-bit/MP3 files slipping through a 24-bit-only profile.

Remove the per-source download-quality dropdowns (Tidal/HiFi/Qobuz/Deezer/
Amazon) — with the global ranked-targets system they were redundant and
conflicting. Add quality_tier_for_source(): picks the LOWEST source tier
that satisfies the user's top target (respects the quality ceiling, saves
bandwidth) or the source's max as best effort. Every source's search +
download + retry path now derives its tier from the global profile instead
of config_manager.get('<source>_download.quality').
Settings keep the per-source allow_fallback toggles; the quality selects are
replaced with a note pointing at Quality Profile.

Quality guard: rejects with a 'file is X, wanted Y' reason (the string the
track-detail modal surfaces), accepts when a target is met or fallback is on,
skips when unprobeable.
force_import isolation: the 'quality' bypass must not skip the AcoustID check
and vice-versa; a quality reject persists trigger='quality' (not 'acoustid')
in the sidecar — so a quality mismatch never routes through the force_import
path (reserved for AcoustID version-mismatch).
Model: lossy matches a MINIMUM bitrate (>=, a range); lossless matches on bit
depth + sample rate, never exact bitrate, so a FLAC's varying bitrate (mono /
compression) can't falsely reject it. v2->v3 migration preserves order.
47 passing across the quality + guard suites.

Add core/quality/selection.py: rank_with_targets() returns (ranked,
satisfied) where satisfied = a candidate meets a real target (strict).
load_profile_targets()/rank_for_profile() are the DB-backed wrappers.
search_with_fallback now skips a source that can deliver no target-meeting
quality and escalates to the next (source priority still wins among
satisfying sources; first source's results kept as fallback unless the
profile disables it). Returns RAW tracks — the satisfied check is a coarse
source gate; match-filtering + final ranking stay in the orchestrator so
the correct track is never pruned. Ranking is fail-open: a ranking error
never drops a source's real results.
Tested: rank_with_targets satisfied/fallback matrix + engine escalation,
stop-on-first, raw-not-pruned, fallback on/off. Amazon field test updated
for the corrected format token.

Add core/quality/source_map.py centralising each source's tier->AudioQuality
mapping (Tidal/HiFi tiers, Qobuz real kHz/bit-depth, Deezer codes, Amazon
codec/tier). Add TrackResult.set_quality() to merge a mapped AudioQuality
onto a result. Wire HiFi, Qobuz, Deezer, Tidal, Amazon search results to
stamp real sample_rate/bit_depth so the global ranker no longer relies on
crude kbps heuristics for streaming sources. Fixes Qobuz/Amazon display
labels ('FLAC 24-bit/192kHz', 'Lossless') breaking format derivation.
Tested: 22 passing (mappers + set_quality merge semantics).
