"""Full-corpus honest metric harness for soothe2-re.
Protects against the Phase B regression: when re-transcribing the structural
FUN_180529fe0 chain (BITEXACT_PLAN step 1), each build must NOT regress below the
committed bridge baseline. This harness:
* runs every dataset case through dsp/build/framed_test,
* measures trimmed 24-bit tone-amplitude error (dB) vs reference wavs,
* writes the results to a JSON file (-> commit as the bridge baseline),
* with --compare <base.json> prints per-group deltas and exits non-zero if the
max per-group degradation exceeds --tol (default 0.25 dB).
Usage:
python3 scripts/corpus.py [--out results.json] [TAG]
python3 scripts/corpus.py --compare baseline.json [--tol 0.25]
Metric (must match AGENTS.md / render_parity.py):
- 24-bit refs decoded with x>=0x800000 => x-0x1000000 (NOT OR-0xFF000000).
- Goertzel steady-state tone amplitude, last 0.75 s window, trimmed length.
