Matiq c85b888745 Δ-rule: wire distance-aware template-local gain (calibration blocked on ph*.npz) 
- delta_gain(bin, kfc, nbin, dist_factor): 1 + (|bin-kfc|/nbin)*RT_DELTA_DIST
  — template-local (farther peaks → deeper cut), dip width const
- delta_mark now stores per-bin gain (was flat 0/1); applied as dm*vlaw_delta
- Default RT_DELTA_DIST=0 → identity (no regression)
- Gated: bridge 1.594, structural 2.689 unchanged; unit checks PASS
- Calibration of dist_factor and STATE-dependence blocked on ph*.npz capture
  (BLOCKMAP:285 — mask chain runs at load time, wine DR EIO)

Matiq a881ee280a AGENTS.md: add vlaw_check to test target list 2026-09-02 23:20:29 +03:00
Matiq 2f854cd1da spectral: vectors instead of new[]; vlaw: extract law + vlaw_check target 
- spectral.cpp: window_/buf_/tmp_buf_/fir_buf_/fir_freq_ as std::vector (no
  exception-leak in ctor, destructor = default)
- framed_model.hpp: extract vlaw_cut/vlaw_mask inline (BLOCKMAP:314 softplus)
- dsp/vlaw_check.cpp: unit test for law (monotonic, zero-level, delta, ref,
  comb-neutral) — PASS
- CMake: add vlaw_check target
- Guard: corpus --compare d=+0.000, fn529fe0_check PASS, twin_check PASS
 2026-09-02 23:19:34 +03:00
Matiq e4c53480ad audit fixes: dead conditional, DBG_CASC gate, dup loop, fft comments, blend doc 
- framed_model: remove `if (pool_w > 0 && !lut_off == false) {}` (empty body)
- framed_model: gate DBG_CASC fprintf behind RT_DBG_CASC (was per-frame spam)
- framed_model: document f6f8 blend 0.8 (decomp 0x5406f8, xmm10 @1824c3e28)
- framed_model: assert(spectrum != nullptr) in processFrame
- spectral: remove duplicate upper-half zero loop in buildFirFromMask
- fft: comment scaling difference (1/N canonical vs 2/half plugin convention)
- Guard: bridge corpus --compare d=+0.000 (exact parity)
 2026-09-02 22:37:09 +03:00
Matiq 197f5edea4 k-mapping: dedup to k_mapping_factor helper, add RT_KMAP_FC 
- Extract k_sens (linear 6->0.44, exp 12->22.0) + k_q log-interp 0.5->1.0 2.0->0.403 into helper
- Replace duplicate blocks for lvl_in/raw_level with single call
- Add k_fc=1.0 + opt-in RT_KMAP_FC via W_eq (gated)
- Gates: bridge 1.594, structural 2.689 (RT_KMAP=1 same, no regression)
 2026-09-02 21:50:38 +03:00
Matiq b41d7a40cb chain: wire IIR4 generator (RT_IIR4_GEN) + add chain smoke test 
- iir4_bidir: env-gated generate_iir4_coefs (C/tau/p/mult/sr) vs proxy kIIR
- fix exp sign: up=exp(-c*g*tau/mult) → down=1-up in 0..1 (was Inf)
- fn529fe0_check: chain_9_19 smoke + generate_iir4 smoke (down0=1 up0=0 ok)
- Gates: bridge 1.594, structural 2.689 (RT_CASC=0) unchanged
 2026-09-02 21:38:44 +03:00
Matiq f2cc0aeaa9 recalibrate: continuous per-fc lerp + additive sens for VLAW (task #1 staged) 
- 800-1200 q<1: lerp 5.0/0.4→4.5/0.35 vs discrete 5.0/4.5/4.0 (block 283-287)
- sens: additive offset (6→-0.48, 24→+0.5) vs overwrite erasing fc choice
- Verified: bridge 1.594 unchanged, structural 2.689 stable (requires campaign.py per-fc fit for <0.5)
- Gated RT_CASC=0, no regression
 2026-09-02 20:25:12 +03:00
Matiq 2201a57ffa docs: update structural baseline 0.341 -> 2.689, document chain gated 
- README: status 2026-09-02 chain919, bridge 1.594 canon, structural 2.689 (L/R e343b0a, RT_CASC=0), hist 0.341 unreachable
- prd.md: sync status, build table, current status 7 with RT_CASC 0/1 columns
- Chain 9-19 blocked on ph*.npz/live-dump (BLOCKMAP:285)
 2026-09-02 20:13:15 +03:00
Matiq 96816f9921 chain_9_19: add IIR4 generator (FUN_180533340) + integrate in audio path 
- Add generate_iir4_coefs() — frequency-dependent warp coefficients from BLOCKMAP:135-150
- Integrate chain_9_19 in process_band_structural via RT_CASC=1 env gate
- chain_9_19 now runs full pipeline: LOG#1→DIVIDE→dc40→FMA→EXP#1→track→warp→LOG#2→IIR4×2→FIR→EXP#2
- IIR4×2 uses double precision (movsd/mulsd per disasm)
- FIR min-phase (52b3cd) enabled
- Canon bridge 1.594 unchanged when RT_CASC=0
- Requires live-dump or ph*.npz capture for input format calibration
 2026-09-02 18:25:14 +03:00
Matiq 2a295af6f3 chain_9_19: integrate into audio path with RT_CASC env gate 
- Pass track_[b] from FramedDetector to process_band_structural
- chain_9_19 called when RT_CASC=1, otherwise identity (warp path)
- Uses unity track (calibrated via live-dump)
- Canon bridge 1.594 unchanged
- Requires calibration of input format for structural chain
 2026-09-02 18:12:10 +03:00
Matiq 9ed22d3476 chain_9_19: enable IIR4×2 (double precision) + FIR min-phase. fix haar test 
- chain_9_19: add track parameter, enable iir4_bidir_340510 and fir_min_phase_52b3cd
- iir4_bidir_340510: use double precision (movsd/mulsd per disasm)
- Fix haar_one_pass test: boundary = 0.5*(a[n-2]+a[n-1]) = 8.0 not 8.5
- All fn529fe0_check tests PASS
- Canon bridge 1.594 unchanged (chain gated by RT_CASC env)

Matiq 5e9c41ad2b fix dual q1.0 misclass: content-aware VLAW, TOTAL 0.568 dual 0.193 
- dual fc500 q1.0 was misclassed as res (5.0/0.3) causing -7.45/4.29 errors
- add has_second_peak + maxlvl>2.0 guard to force dual law 3.22/0.49 for 2-tone content
- res_500 stays 0.006, dual_1.0 now 0.05/0.24, TOTAL 0.568 vs bridge 1.594
- keeps RT_KMAP/RT_DELTA_STATE opt-in off, VLAW canon now 0.568

Matiq 746b51c047 k-mapping fix: apply to raw_level VLAW path, keep opt-in default off 
- KMAP now applied to both lvl_in and raw_level (VLAW uses raw_level directly)
- KMAP default 0, VLAW canon TOTAL 0.732 (vs 1.523 when enabled — table k over-corrects, needs campaign fit)
- RT_DELTA_STATE placeholder no-op pending live STATE capture (24ii2/24ii3 g=12.15 vs 1.85)
- Keeps bridge 1.594 < VLAW 0.732 canon, dual max 7.457 outlier remains for q=large
