P4: transcribe exact FUN_180529fe0 mask chain (structural, not yet calibrated)
framed_model.cpp now follows the decoded mono-path structure:
level -> scale(0x540870*0x54088c/0x1a0) -> IIR1 leaky(A1/B1) -> IIR2(A2/B2)
-> exp2(0.5*(mask-blend)) -> combine/acc -> warp -> IIR3(A3/B3)x2 -> dry/wet
IIR stages are the real live tables (iir_leaky y=A*acc+B*x, B=1-A). Removed the
empirical mask_lut=(1/(1+K*acc))^n. Not numerically calibrated yet: exp2 bigkernel
exact semantics + PRNG prologue (fVar30) + FFT-conv still TBD; t1kq depth -2.9 vs
-14.98 dB ref.

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.
