## Статус (24mm14+, 2026-08-29) — ЕДИНСТВЕННЫЙ ИСТОЧНИК TOTAL ## Статус (2026-09-02, chain919) — ЕДИНСТВЕННЫЙ ИСТОЧНИК TOTAL
**Новый канон (структурный `render48k` 48k/4096 `VLAW+EQ`, `RT_VLAW=1 RT_SYN=1 RT_NOWARP=1 RT_NOIIR3=1 RT_IIR12=0 RT_EQ=1`): TOTAL 0.341 dB** (dual 0.193/0.438, res 0.284, comb 0.81, t1k 0.36, max `1.17` `t1kq_1200`). **Старый bridge (`framed_test` 44.1k) 1.594 dB** (`scripts/baseline_bridge.json`) — превзойдён на `1.25`. Guard: `python3 scripts/corpus_structural.py --out /tmp/v.json` (канон `0.341`) + `python3 scripts/corpus.py --compare scripts/baseline_bridge.json --tol 0.25` (bridge). Следующий шаг — `2. k-маппинг twin/am` (`handoff/BLOCKMAP_529fe0.md:22v` `FilterGraph` до детектора) для снятия `per-fc` (`800/1200`). Детали — `handoff/NOTES_LEVEL_INDEX.md`. **Bridge (`framed_test` 44.1k): TOTAL 1.594 dB** (`scripts/baseline_bridge.json`, guard `--tol 0.25`). **Структурный `render48k` 48k/4096 L/R (`RT_VLAW=1 RT_SYN=1 RT_NOWARP=1 RT_NOIIR3=1 RT_IIR12=0`): TOTAL 2.689 dB** (dual 2.04, t1k 5.43, max `6.8`). Исторический канон `0.341` (24mm14, `f40f41e`) недостижим на текущем `HEAD` (L/R `e343b0a` + chain gated `RT_CASC=0`); требует перекалибровки `per-fc`/`EQ`. Guard: `python3 scripts/corpus_structural.py` + `python3 scripts/corpus.py --compare scripts/baseline_bridge.json --tol 0.25`. Chain 9–19 интегрирован (`RT_CASC=1` gated, IIR4 double + FIR min-phase) но некалиброван (`31.6` при включении, блокер — входной формат level vs cut). Следующий шаг — калибровка chain по live-dump/`ph*.npz` (BLOCKMAP:285). Детали — `handoff/NOTES_LEVEL_INDEX.md`, `.opencode/plans/chain919.md`.
