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.
