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.

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).

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.

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).
