check_flac_bit_depth now delegates to check_quality_target, which probes the real file and treats bit depth as a MINIMUM (24-bit satisfies a 16-bit target) — the old context-string parsing, per-quality bit_depth_fallback, and 'reject higher bit depth' semantics are gone. Rewrite the wrapper tests to the probe-based model and update the rejection-reason assertion to the unified 'quality filter' wording. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

"""``check_flac_bit_depth`` is a thin legacy wrapper that delegates to the
|
|
unified ``check_quality_target`` guard, which probes the REAL file (mutagen)
|
|
and ranks it against the v3 ranked-targets list.
|
|
|
|
The old per-quality ``bit_depth_fallback`` config and the "reject a higher bit
|
|
depth" semantics are gone by design: bit depth is now a MINIMUM, so a 24-bit
|
|
file satisfies a 16-bit target. These tests pin the wrapper's current
|
|
behaviour (deeper coverage of ``check_quality_target`` lives in
|
|
``tests/imports/test_quality_guard.py``).
