phase A: reduction law found (affine in dB), canon unchanged; keep RT_DUMP tooling
...
- Effective reduction is affine in dB(lvl): x_exp2 = -0.6646 - 0.05877*dB
(mask ~ 0.8*lvl^-0.354, gamma ~= decomp 0.344); tones +-0.13 dB over 42 dB
- Pre-IIR calibrated variant (X0=1.8/S=0.11): TOTAL 2.633 vs HEAD 2.286;
wins t1kq/t1k/al/comb, loses res/dual -> gate fails, canon stays LUT
- Grid search (X0,S,floor,CMAX) on validated trajectory model: no scalar
law of the family fits tone+noise simultaneously (res tension)
- Refuted: high-bin/IIR3-backward propagation, direct-affine bypass,
positive floors, ceilings
- Kept opt-in instrumentation RT_DUMP_BIN / RT_DUMP_ALL for Step 7 capture

docs: sync BITEXACT_PLAN/roadmap/AGENTS to 2026-08-21 state
...
BITEXACT_PLAN: structural column in S0 table; Step 2 re-scoped (combine
thunk semantics, acc has no single-band consumer; FUN_1805316e0 is a
coefficient writer NOT a mask combiner — fixed in Steps 2/8); Step 4
FFT-conv downgraded to P3 (window near-flat); Step 6 pipeline done
(render48k); entry point = saturation hunt then Step 7 capture.
roadmap: status 2026-08-21, P4 row + ~80% estimate with dual-canon results.
AGENTS: two-canon model description, render48k/corpus_structural commands,
stale-binary sweep hazard warning, updated gaps list.

P4: AGENTS.md — honest baseline state (log-domain LUT bridge, correct 24-bit metric)
...
Replaces stale exp2(am/res) chain description + wrong metrics with the actual
honest state: C=G*LUT(log10(am/res))+W*warp^A, gain=(1-C)*res^rp; dual<=0.72,
fc-scan<=0.59, corpus mean 0.77. Documents the 24-bit metric trap, negative
broadband test, and the remaining structural gaps (combine + FFT-conv, A/B/gamma).

docs: AGENTS.md + refresh README/roadmap/summary/SESSION_HANDOFF to P4 canon; rm empty logs
...
- AGENTS.md: canonical build/test commands, honest trimmed tone metric, current
bit-exact state (mask-apply chain), open gaps (PRNG/FFT-conv/exp2/SR-mismatch).
- README.md: status moved to P4 (C++ FramedDetector canon, framed_test), historical
B.1..B.15 numerical model demoted to <details>; structure/doc table updated.
- roadmap.md: P4 phase marked progress, P4.1/P4.2/P4.3 milestones, top status refresh.
- summary.md: marked historical (behavioral v4).
- SESSION_HANDOFF.md: fixed stale "NOT DECODED" (now decoded), copy note done.
- Removed empty tmp_spec.txt/giant3.txt and untracked .log/__pycache__ clutter.
