Matiq f483fe398d 24a: perf_event breakpoints definitive — wine reserves HW BP slots (ENOSPC on wine threads while self/cross-process native opens succeed), closing hardware-trap route and explaining all prior ptrace-DR silence; FFT-conv engine object identified at ctx+0x540530 (inline cfg {2,4096}/{16384,8192}, member vectors +0xb8..+0x130, methods dc30/fe00/dd30) — its process method is the kernel consumer candidate 2026-08-24 02:43:04 +03:00
Matiq 8acbf6612e 23m: round final — DR-trap delivery anomaly under wine threads documented (near-zero stops despite verified arming and confirmed module execution); full stop-logging added to fnexec; roadmap to bit-exact fixed: G-form via stabilized series, consumer via init-family decode or perf_event HW breakpoints, then RT_FIRCONV gate 2026-08-24 02:30:19 +03:00
Matiq 56edd3c0f4 23l: DR exec-watch verified working end-to-end by micro-test on this kernel (SIGTRAP+DR6 correct); contradiction isolated to process/thread targeting in tracer, single remaining hypothesis documented with debug protocol 2026-08-24 02:22:55 +03:00
Matiq baafbb6dc6 23k: HW exec-breakpoints operational (correct offsets, RF-flag pass, clone inheritance); clean run proves decoded chain does NOT execute in steady render — kernel built ONCE on param-change in <100ms window after instance creation; transcription implication: rebuild kernel only on setParams; full capture recipe documented 2026-08-24 02:08:30 +03:00
Matiq 9e85b730b2 23j: multi-register watchpoint definitive negative — zero hits even on mandatory-hot words (overlap/R/lock) across confirmed renders with 8/8 threads armed; HW data watchpoints not delivered under wine threads here — route closed, pivot to static table-index scan 2026-08-24 01:56:15 +03:00
Matiq 25b736b2bb 23i: hardware watchpoint infrastructure working (u_debugreg base 0x350, LEN8 rejected -> use LEN4, DR6 reset documented); zero hits on kernel word — consumer may read a copy or builds early; fnwatch.py committed 2026-08-23 23:31:26 +03:00
Matiq 05caf1eb44 23h: kernel-consumer hunt — no direct readers of FIR data outside 529fe0 (init-only xrefs); bp on loop end silent in render => duplicated chain instantiation suspected; active RIP sampler fnsample.py working (2.4k in-module samples, MSVC stackfill dominates steady state; core leads 52e1c0/534580 on param phase); yabridge stale socket dirs break respawn — documented 2026-08-23 23:01:19 +03:00
Matiq c3656975dd 23g: amplitude sweep attempt inconclusive (phase-stability control needed); scripts committed 2026-08-23 22:30:39 +03:00
Matiq 70cafc1700 23f: live scratch series across q sweep (11 configs) — center strictly constant over q, x1.805 hits real cuts within 0.14dB at both known points, scr171(res) nonlinear consistent with 22x exponent; detector smoothing located between raw bands[] write and DESIGN (raw blinks 0.3..382 while scratch steady) 2026-08-23 22:27:13 +03:00
Matiq 7902acfbb8 23e: law closed quantitatively — FIR=exp(0.984*scratch) pointwise; real/FIR cut ratio constant 1.80 across configs and bins (linear post-scale, EMPIRICAL until conv-stage decoded); center independence of q proven live (scratch43 -0.6565 vs -0.6551); skirt shift matches within 3% (1.46 vs 1.50 dB) 2026-08-23 22:19:05 +03:00
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 738ffccad4 22z: mask->FIR call sequence decoded (535a70 thunk chain -> 1802a24c0 body; WIN_freq second-half segment multiply; FIR[0]=1,FIR[1]=0); IDFT-window-DFT spreading hypothesis NUMERICALLY REFUTED (max 2.6dB at skirt vs needed 11.8) -> dual skirt mechanics live in detector/template domain, not post-processing 2026-08-23 18:55:36 +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 13c2d028bf 22w: faithful mask-shaping chain v1 behind RT_FAITHFUL (fnfaith.cpp) — exact 180533340 freq-warped bidir-IIR coefficients (fc_bin=85@48k/4096, constants from dump); corpus TOTAL 5.315 but comb 2.57 best-ever; decisive: mask shape cannot balance dual tones -> level contrast is created by the DETECTOR (time-domain twin bank hypothesis priority #1) 2026-08-23 17:04:23 +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 3b9158e63e 22r: affine dB law (RT_LAWAFFINE) ported onto bare chain — TOTAL 1.931 beats canon 2.286; A=7.4/S=1.85 best, tradeoffs mapped 2026-08-23 11:01:42 +03:00
Matiq d160acaa27 22q: dual diagnosis — twin-divisor contrast refuted (real cuts both tones equally), saturating dB-curve hypothesis; pair-collection plan 2026-08-23 10:39:24 +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 d4e8d055c6 22o: RT_ENV=live (live-table envelope) — noise TF better, corpus neutral; new-arch best 5.386 vs canon 2.286; joint fit next 2026-08-23 03:52:12 +03:00
Matiq 0861a64387 22n: live ctx found (0x2370048, scalars config-dependent!), slow detector adaptation discovered (gain deepens over ~seconds, kRTrel tau~2s) 2026-08-22 22:33:16 +03:00
Matiq 709d8ce227 22m: user hypotheses tested — gamma!=delta (E1), BandConfig stable under depth/delta (E3), no level-path refs in SpectralProcessor methods (E4) 2026-08-22 21:56:46 +03:00
Matiq 98a35e8648 22l: pool5+scale1.144+floor hits tone floor -20.74 (real -20.72); corpus 5.9 — params need systematic fit; canon untouched 2026-08-22 21:33:31 +03:00
Matiq 355ce828f4 22k: bare exp2 chain CONFIRMED on white-noise probe; remaining tone gap = detector level scale x1.14 2026-08-22 20:58:18 +03:00
Matiq dee3864c3c 22j: white-noise probe — real TF is flat (warp not output multiplier), reduction is contrast-driven; adaptive-twin lead 2026-08-22 20:22:23 +03:00
Matiq d43bbfe66b 22i: RT_LVL_CAP inert (model post-IIR levels ~1.06 << cap) — gap relocated to detector front-end amplitude chain 2026-08-22 19:51:56 +03:00
Matiq 94383b15d3 22h: floor law mapped — floor_dB(sens)=20log10(ln10/20)-(sens-6)/3, depth shifts too; exact anchor sens6=ln10/20 2026-08-22 19:46:22 +03:00
Matiq ef7d3f49c7 22g: NO-LUT test isolates gap to detector front-end; unified sidechain-clamp hypothesis (knee at 0dBFS, identical renders above) 2026-08-22 19:39:22 +03:00
Matiq 41b0d3c250 22f: floor discrimination via param bridge — dry/wet crossfade confirmed, floors=k*ln10/20, detector-cap hypothesis leads 2026-08-22 19:10:50 +03:00
Matiq 3970c1e309 22e: floor algebra solved — gain_floor=20log10(blend*ln10/20), matches -20.72dB within 0.006dB; lead FUN_180529c60 2026-08-22 18:54:48 +03:00
Matiq 9c14a74318 docs: 22d — hard gain floor -20.72dB mapped (t-clamp live confirmation); cold/hot discrepancy open 2026-08-22 18:40:13 +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 3e5085e06d phase A: reduction law found (affine in dB), canon unchanged; keep RT_DUMP tooling 
- Effective reduction is affine in dB(lvl): x_exp2 = -0.6646 - 0.05877*dB
  (mask ~ 0.8*lvl^-0.354, gamma ~= decomp 0.344); tones +-0.13 dB over 42 dB
- Pre-IIR calibrated variant (X0=1.8/S=0.11): TOTAL 2.633 vs HEAD 2.286;
  wins t1kq/t1k/al/comb, loses res/dual -> gate fails, canon stays LUT
- Grid search (X0,S,floor,CMAX) on validated trajectory model: no scalar
  law of the family fits tone+noise simultaneously (res tension)
- Refuted: high-bin/IIR3-backward propagation, direct-affine bypass,
  positive floors, ceilings
- Kept opt-in instrumentation RT_DUMP_BIN / RT_DUMP_ALL for Step 7 capture
- Docs: NOTES_LEVEL 21d, BITEXACT_PLAN s.0 note, roadmap, AGENTS

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 2d69b85aa3 P5: NOTES — F5c DSP-FFT 0x140a70 status (P3 confirmed unwired; all check targets PASS) 
Full dsp/ check sweep green. fft.cpp = numerical radix-2 (std::cos) not bit-exact
0x140a70; split-radix butterfly + plan-gen giant + sin-table loader remain (multi-week
P3). Required only for FFT-conv byte-parity, not for the bridge renderer.
 2026-08-20 21:09:28 +03:00
Matiq d802ee7aed P5: F5b — exp2 0x26b820 assets extracted bit-exact + numeric fallback exp2_dsp 
Extracted the 8x16 irrational tables + lead-in -708.4xx series from soothe_mem.bin
into exp2_tables.{hpp,cpp} (P3 bit-exact inputs). exp2_dsp = numerically-correct
double exp2 matching std::exp2 (wiring fallback; NOT bit-exact yet — the plugin
body has special subnormal/overflow branches and a vfmadd213sd poly not yet 1:1).
exp2_check: 2e6-grid PASS (0 cells >1e-13).
 2026-08-20 21:07:30 +03:00
Matiq 4e9c1b1ed7 P4: F4 geometry test — internal 48000/4096 does NOT close residual (0.68 vs 1.00); all structural adaptations rejected 
Tested internal-geometry (48000/4096 + resample) — worse. Combined with earlier
negative results (parametric LUT x6, FFT-conv window, combine acc), every structural
adaptation is rejected. Bridge (Pchip 0.774) = empirical ceiling. Bytes require live
A/B/gamma capture or bit-exact exp2/FFT kernels.
 2026-08-20 20:54:05 +03:00
Matiq fa1ef205df P4: F2 structural wiring tests — combine+FFT-conv naive wiring both regress (doc only) 
Wiring FFT-conv step5 (mask*=win) gives mean 5.2, combine/acc (att/rel from kRTAtt/
kRTRel) gives 4.7 vs base 0.75-0.80 on representative subset. Both belong to the
exp2(mask) structural chain (blend 0.8 + bigkernel) NOT the fitted bridge final-gain.
No code change; bridge + Pchip stays canonical (0.773).
 2026-08-20 20:52:00 +03:00
Matiq 1cfe013939 P4: bench all existing parametric LUT sets on full honest corpus — Pchip remains best (0.773) 
All previously-derived parametric LUT forms (u563a60 A=-13.78/68.29/0.344, lut5/
lut4 gamma-LUT, power-law, linear 0.483/0.717, real extracted points) tested on the
full 59-case honest 24-bit metric within one fixed bridge pipeline. None beat the
committed Pchip (0.773; worst powerlaw 6.8). F1 closed: parametric curve production
was already done, none accepted; structural A/B/gamma from ctx+0x188 remains the only
path to bytes (blocked on level-path object live capture).
 2026-08-20 20:44:20 +03:00
Matiq cea562b511 P4: F0 GATE PASSED — output is byte-deterministic; re-renders reproduce committed refs exactly 
Two test RPPs (res_only1_500 4s, t1kq_only1_1000 6s) rendered twice each via
reaper -nosplash CLI. Data chunks identical across runs AND byte-identical to the
committed reference wavs. Whole-file differs only in the bext render-timestamp.
=> bit-exact (bytes) is REACHABLE; the per-run-dithrandization blocker is closed.
Next: exact structural chain + kernels + internal 48000/4096 geometry + live A/B/gamma.
