From 7a74c99faab763c9c067c1532818ba669df21169 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 3 Jul 2026 07:22:39 +0000 Subject: [PATCH] =?UTF-8?q?fix(eval):=20make=20the=20synthetic=20fundament?= =?UTF-8?q?als=20gate=20real=20=E2=80=94=20post-#201=20review?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Review of #201 found the committed gates had never been run: 'asa verify' was red on main (3 failing default-manifest checks) and the synthetic manifest failed 52 of 140 checks. This commit makes both gates green with honest measurements and records the first accuracy baseline. Generator (build_synthetic_corpus.py): - Engineered band-disjoint one-shots replace product drum samples in fixtures: the kick's pitch-sweep onset/click landed in the snare band (16 kicks counted as snares) and product hats never cleared the hat detector's floor. Kick = 50 Hz sine, 20 ms fade-in (sharper attacks splatter into the snare band), 0.20 s length (its low-band tail otherwise turns -64 dB snare residue into countable local maxima); snare/hat = band-passed bursts with an extra HP pass. - Grid clips are a bare accented-kick pulse: 'and' hats bin ambiguously in analyze_time_signature's ±half-beat onset counting and flipped 4/4 reads to 3/4 or 6/8. Swing clips keep swung hats but check BPM only. - Chord labels computed from pitch classes, flat-spelled to match the Viterbi vocab (hardcoded sharp table scored 0.25 on F# major). - Bass fixture gets --transcribe (was missing → guaranteed noteF1 0). - expected blocks carry active checks only; ground-truth-for-later (swing %, hit times) moves to a separate 'truth' key. - Dropped the [:28] truncation that silently discarded multi_F_major; one-shots carry their own seeds (order-independent determinism). Harness (fundamentals_evaluation.py): - Enharmonic pitch-class folding for key + chord comparisons ('C# Minor' == 'Db minor', 'Gb' == 'F#'); relative-key table replaced with pitch-class math. - knownGaps: per-track check names that still run and report scores but don't gate — measured baseline weaknesses stay visible as improvement targets (8 at baseline: odd-meter detection + downstream downbeats, tempo octave at 174, 7/8 tempo wobble). Trust layer (fundamentals_quality.py): - bpmAgreement=True with confidence >= 0.5 is authoritative: a BPM measured exactly right and cross-confirmed by Percival was being hedged as 'cross-check not strong enough'. CI: the default-manifest fundamentals gate (render + --fail-on-skip) now runs in the backend job — #201 merged green because CI never executed the gate it shipped. Baseline: audits/accuracy-baseline-2026-07-03.md — 29 clips, 54/54 active checks green, 8 knownGaps quantified. Backend suite: 1283 tests OK.
