Matiq 3a0a38467b 23d: BREAKTHROUGH — live kernel captured via SIGSTOP sampling of offline render (rendersnap.py); bands[] input to DESIGN is the raw per-frame signal spectrum (Hann lobes at tone bins only!), captured FIR shows skirt cut deeper than center exactly as real output (0.473@2000 vs 0.524@500) despite R-curve claiming otherwise; am/res structure confirmed with twin template as divider; recipe for exact ops formula next round 2026-08-23 22:11:33 +03:00
Matiq 0a45661a25 23c: negative feasibility — symmetric log-domain convolution cannot reproduce dual skirt geometry (best 0.94dB err at absurd 324-bin width); narrows mechanism to non-symmetric ops / true bands[] input / temporal coupling; capture recipe for DESIGN-input dump documented 2026-08-23 21:09:14 +03:00
Matiq b8d5f83fc5 23b: mask->FIR chain decoded — DESIGN body is vectorized LOG2 of band curve (poly fingerprinted), WIN_freq identified as periodic Hann(4096) falling half applied to FIR[n/2..n), full ILT stub->impl table resolved offline (ilt_resolve.py), live buffer catalog extended (SIMD lane masks at 0x540598, complex identity reset between callbacks, overlap buffer at 0x5406f8 non-zero), plugin output proven nondeterministic across renders (LCG dither) — spectral metrics only; ptrace lab scripts + lessons (TRACECLONE before CONT, sub-second host lifecycle under -renderproject) 2026-08-23 20:59:54 +03:00
Matiq 91101b2135 22y: live ctx capture pipeline works (scripts/dualtrace.py, realtime playback + chunked heap snapshot); found config-dependent reduction curves 0x540768/788/7f8 (peak follows band fc; 7f8 min exactly 1.0 => R=1/mask, notch-shaped); acc/f6f8 arrays ZERO in steady state; DECISIVE: applied filter != pointwise R (dual skirt 3dB vs real 11.8) -> FFT-conv wide-window spreading is the missing mechanism 2026-08-23 18:40:25 +03:00
Matiq 64beaa7131 22x: NO-alpha theorem — no res-exponent makes detector level consistent across families (dual needs alpha<0, fc-scans break at alpha<=0); dual-vs-q table: cut@center CONSTANT across q, skirt cut falls ~exp(-res/0.49) converging at res>=2 -> notch geometry lives in the fine-grid twin template (536300), not per-bin arithmetic; pointwise (am,res^alpha)+single-law class REFUTED 2026-08-23 18:04:47 +03:00
Matiq 79c11dc220 22u: raw-asm re-decode of FUN_180529fe0 — multiband pre-combine inside method, per-band scale->kernel->2x bidir-double-IIR (52d650 fully decoded, per-bin double coefs), band-state arrays 0x540768[i]/0x5407a8[i]; 0x5407c8 acc has NO runtime reader (21b addr wrong); offline bidir-IIR smoothing hypothesis REFUTED (monotonic degradation) 2026-08-23 15:53:58 +03:00
Matiq 376bd955c9 22t: two-factor laws REFUTED by descent (quad Q->0, resrp rp->0 — geometry already in lvl=am/res); real render of sim-optimum 7.6/1.694 = 1.898 with group regressions, canon stays; error budget: dual = 62% of corpus abs-error -> inter-band acc/f6f8 consumer is priority #1 2026-08-23 15:10:06 +03:00
Matiq 3857205a6b 22s: offline law-fit infra (full replay sim, 2s/corpus) — NO single affine (A,S) exists even on pure tones; family slopes 0.85-2.19, global LSQ resid 0.60 dB structured by rms/fc-dist; scalar law saturated ~1.87-1.93, canon stays HEAD 2026-08-23 14:36:27 +03:00
Matiq 0aeedde019 22p: joint-fit grid — floor essential (without: corpus x2), optimum scale=0.90 TOTAL 5.215, comb beats canon first time; canon stays HEAD 2026-08-23 09:48:17 +03:00
Matiq f5ef81667c bench: official param bridge (setparam/dump_params.lua) + rpp_setparam format tool; 22c — XML params decorative, depth=+-18dB, trim=+-24dB, reduction curves measured 2026-08-22 18:28:54 +03:00
Matiq 7fac8b2a4f step7: live BandConfig capture infra + FUN_180563a60 decode — GUI-only, audio path refutes premise (22b) 2026-08-22 15:28:01 +03:00
Matiq c222e054ca docs: Phase B recovery — 4 offline detector hypotheses refuted; scripts into scripts/ 2026-08-22 12:55:02 +03:00
Matiq b2cb9235be feat(scripts): structural-path full-corpus harness + first honest 62-case numbers 
corpus_structural.py drives render48k (48k/4096 structural chain) across the
full corpus with bridge-compare mode. Results: comb 6.12 vs bridge 10.15
(structural wins multiband already), res better, single-band worse; dual@500
constant -6.7dB q-independent over-cut exposes missing reduction saturation.
Param sweep (gamma x MULT, verified builds) confirms current optimum; curve
SHAPE is the gap -> Step 7 capture or bigkernel input re-examination.

Matiq fa71240d92 test: add validation harness (scripts/corpus.py + bridge baseline) to prevent Phase B regression 2026-08-21 01:06:05 +03:00
