Matiq ddf2ac2050 P4: lock PRNG prologue + correct constants (DAT_*=1); scale via prng_fvar30
CRITICAL fix: soothe_mem.bin is VA-linear (offset=RVA). DAT_18262b5c8/b704/b700
are INT 1 (cvtdq2ps -> 1.0), NOT the 0.4552/0.6089/0.6070 read earlier via a bad
section offset. Transcribed FUN_180529fe0 PRNG prologue into prng_fvar30():
fVar30=(int)(LUT[s+1]*LUT[s]+0.001). At live state 112 this is deterministically
1.0 over 300 frames, so scale level *= (1/2048)*440.95 is not randomized in
practice. Scale coefficient now computed structurally; t1kq unchanged -0.43 dB.

Matiq bdf9f21a60 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.

Matiq 77b639ee82 chore: fix .gitignore to track decompiled .dis/.bin disassemblies
.gitignore used '*' as ignore-all with only extension whitelists, so the 128
handoff/nls_dasm/*.dis + 6 *.bin disassembly outputs (f_563a60, f_56e3e0,
f530850_full, f_52b570, fft, twin, ...) were NOT tracked - data-loss risk.
Now un-ignore handoff/nls_dasm/*.{dis,bin} explicitly. Heavy .bin dumps
(soothe_mem.bin etc.), logs, wav/rpp, dl/lib/bin/ghidra-proj stay ignored.

Matiq 0d262461ea P4: lock bigkernel semantics (exp2(-mask)*blend) + calibrate scale
Read the 0x26b820 SIMD loop: the exp2 result is multiplied by the blend buffer
(vmulpd at 0x18026bba0 with ymm11=blend) => mask = exp2(-level)*blend, sign
inverted for attenuation. framed_model.cpp corrected to exp2(-scratch)*0.8.
Calibrated level_scale=600 -> t1kq err -0.06 dB (ref -14.98). comb per-tone
errors reduced (max ~7.8 dB); warp/FFT-conv smoothing still approximated.

Matiq f23bbfa1f6 P4: decode FUN_180529fe0 mono-path exactly + extract live mask tables
Full decomp of the per-band mask-apply loop (scale -> IIR1/2/3 leaky ->
blend -> exp2 bigkernel -> combine/accumulate -> dual warp -> dry/wet -> FFT-conv).
Extracted runtime tables to rt_mask_tables.{hpp,cpp}: IIR A1/B1,A2/B2,A3/B3
(leaky y=A*acc+B*x, B=1-A), warp 0x5406a8, per-band 0x540768, PRNG LUT 0x5408b0.
bigkernel 0x26b820 = vectorized exp2 (log2e/floor/mantissa tables). Fixed the
broken warp line in framed_model.cpp (compiles again).

Matiq fc48a9fee4 P4: real mask chain in FramedDetector (level-tracker + accumulator + live-calibrated LUT), t1kq err 0.5dB
Replace empirical PCHIP detector with live-calibrated mask chain from FUN_180529fe0:
  level = am*res*scale; track += w*(level-track) (per-bin attack/release weights
  extracted from RT snapshot, rt_weights.hpp); acc = (level-track)+level; mask =
  (1/(1+K*acc))^n (K=9.8026 n=0.25966 fitted to live mask band0). min-combine.

Results (N=2048 hop=512): t1kq single-band err +0.51 dB (-14.47 vs -14.98 dB ref);
comb 4-band per-tone -3.4..+5.8 dB (old PCHIP over-cut comb ~6 dB). Adds framed_test
harness for C++ FramedDetector eval on tone1kq/comb.

Matiq 28cd3b7c62 Q-dep rp + honest TRIMMED metric: mean=0.175 (was misleading 0.144 artifact)
- Exposed artifact: earlier fits measured tone_cmp on untracked-length output
  (nfr*HOP+N); framed_render.synthe trims to len(x). Honest scalar-rp=0.0169
  baseline is 0.280, not 0.160 as previously recorded.
- New model: rp(Q)=rp0*Q^drp, G/W/A/rp0/drp=0.9963/0.3335/0.9807/0.0275/0.2159.
  Trimmed errs: q0.1 0.000/0.001, q1 -0.256/-0.707, q10 +0.086/+0.001.
  q0.1+q10 perfect; bottleneck q1@2000 (structural warp mismatch).
