corpus_structural.py drives render48k (48k/4096 structural chain) across the full corpus with bridge-compare mode. Results: comb 6.12 vs bridge 10.15 (structural wins multiband already), res better, single-band worse; dual@500 constant -6.7dB q-independent over-cut exposes missing reduction saturation. Param sweep (gamma x MULT, verified builds) confirms current optimum; curve SHAPE is the gap -> Step 7 capture or bigkernel input re-examination.

"""Structural-path full-corpus harness (render48k, 48000/4096 internal grid).
|
|
|
|
Mirrors scripts/corpus.py but drives dsp/build/render48k (structural
|
|
FUN_180529fe0 chain on the internal grid) instead of framed_test (bridge).
|
|
Purpose: honest per-group comparison of the structural chain against the
|
|
committed bridge baseline (BITEXACT_PLAN step-1 criterion: structural must
|
|
not regress below bridge on single-band groups).
|
|
|
|
Usage:
|
|
python3 scripts/corpus_structural.py [--out results.json]
|
|
python3 scripts/corpus_structural.py --vs-bridge scripts/baseline_bridge.json
