Matiq 07cd4b7dc0 23a: docs sync to post-22z state — AGENTS header/open-gaps/key-files and BITEXACT_PLAN entry-point updated: priority #1 = bands[] input semantics (static decode of conv body or in-callback trace), canon stays LAWAFFINE 7.4/1.85 TOTAL 1.931, refuted branches documented 2026-08-23 19:00:44 +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 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 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 34156315e6 22v: full block map of FUN_180529fe0 from raw asm — 4 bidir-IIR states, per-band acc array [0x5407c8+i*16] confirmed (21b semantics), ILT thunk table resolved; coefficient generator decoded (530b60 + 533340): frequency-warped one-pole g=fc/i below crossover — the real mask smearing mechanism; full disasm f529fe0_full.dis (old was truncated at 52a813) 2026-08-23 16:47:51 +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 bf8c12603c readme: sync to 22i — P5 status, floor blend*ln10/20, Step 7 refuted, detector front-end priority, new tooling 2026-08-22 20:02:11 +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 7febe744e9 plan: sync to 22e — Step 7 refuted, floor blend*ln10/20 solved, new priority Step 9 (floor mechanism) 2026-08-22 18:59:04 +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 71644ff3e6 fix(render48k): chunk-scan WAV loader — hdr[40] is not data size when bext/junk present 2026-08-22 10:59:26 +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 702b74e297 docs: sync BITEXACT_PLAN/roadmap/AGENTS to 2026-08-21 state
BITEXACT_PLAN: structural column in S0 table; Step 2 re-scoped (combine
thunk semantics, acc has no single-band consumer; FUN_1805316e0 is a
coefficient writer NOT a mask combiner — fixed in Steps 2/8); Step 4
FFT-conv downgraded to P3 (window near-flat); Step 6 pipeline done
(render48k); entry point = saturation hunt then Step 7 capture.
roadmap: status 2026-08-21, P4 row + ~80% estimate with dual-canon results.
AGENTS: two-canon model description, render48k/corpus_structural commands,
stale-binary sweep hazard warning, updated gaps list.
2026-08-21 13:54:06 +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 a9d5581ad8 docs: NOTES — IIR3 bidirectional decode, combine thunk semantics, Step 2 re-scope 2026-08-21 12:55:23 +03:00
Matiq 1a616e1b7b feat(dsp): IIR3 bidirectional per decomp (fwd+bwd x2), combine semantics decoded
Decomp (consumers_out.txt:955-1075): IIR3 = TWO [reset,forward,backward]
pairs, state persists fwd->bwd; y = B3*x + A3*state. Replaces 2x forward.
Combine block decoded from thunks: f6f8 = mask - acc (8d60, dst=3rd arg);
f6f8 += kRTAtt/kRTRel * acc (halves); acc += mask (5a20). KEY FINDING:
in online single-band path acc/f6f8 have NO consumer before warp/dry-wet
- combine affects output only via multiband/FFT-conv stages (Step 2 scope
narrowed). LUT_MULT retuned 4.4 -> 4.2. Smoke mean|err| 0.993 -> 1.021
(faithful transcription kept over tuned fwd-only). Checks PASS, guard PASS.

Matiq 9ffe60e66e feat(dsp): wire IIR3 x2 (kIIR_A3/B3) post-warp into structural chain
Step 9 of NOTES_LEVEL:820-840 mono-path (was missing; roadmap claimed it).
Light spatial mask smoothing, upper half re-mirrored. LUT_MULT retuned
3.8 -> 4.4 for the shifted calibration. Smoke (48k/4096): mean|err|
1.093 -> 0.993 (t1kq -1.06, t1k +1.66, al12 -0.26). Module checks PASS,
corpus --compare bridge baseline PASS.

Matiq 7a108c529a docs: NOTES_LEVEL update — LUT level-domain discovery, sweep tooling hazard 2026-08-21 12:36:35 +03:00
Matiq 535b150f75 feat(dsp): move dB-LUT to level domain (pre-IIR/exp2) in structural chain
Mask-domain LUT clamps t<0 on loud input (t1k mask_dB < A=-13.78) causing
-24dB over-cut. Level-domain keeps quiet/loud inside [A,B] domain:
t1k err -24.04 -> +2.45 dB (3-case smoke: mean|err| 8.2 -> 1.09).
Params: gamma=0.344 (decomp-extracted), mult=3.8 (placeholder, empirical).
Module checks pass; corpus (bridge path) unchanged at 1.594.
2026-08-21 12:35:57 +03:00
Matiq 9b7e9d3099 feat(dsp): add dB-domain LUT (FUN_180563a60) to structural chain on 48k grid
- Add BandConfig A/B/gamma LUT compression (extracted from refs: A=-13.78dB, B=68.29dB, gamma=0.344)
- Add res^rp smoothing term for bridge-parity (RP0=0.0275, DRP=0.2159)
- Calibrate scale_factor to match bridge gain at tone bin (15.0 * 440.95 / 2048 = 3.23)
- Structural 48k: -26.81 dB vs ref -27.23 dB (err +0.426 dB)
- Bridge baseline: intact (0.000 dB degradation)
- All module checks PASS (fn529fe0, exp2, twin, tables, leveltrack, levelpath, fftconv)
2026-08-21 09:25:17 +03:00
Matiq 6924e539e0 feat(dsp): render48k pipeline + structural chain on 48000/4096 grid
- render48k: resample 44100→48000, process via SpectralProcessor(4096,1024,48000),
  resample 44100, write 24-bit stereo WAV
- FramedDetector: structural chain (fn529fe0 sequence) runs on 48000/4096 grid,
  bridge path unchanged for 44100/2048
- Structural chain: scale→IIR1→copy→IIR2→mirror→blend→exp2→combine→warp→dry/wet
  using live tables (kIIR_A1/B1, kIIR_A2/B2, kBand768, kWarp, kRTAtt/kRTRel)
- Bridge baseline intact (0.000 dB degradation)
- 48k tone test: -20.73 dB vs ref -27.23 dB (6.5 dB error, scale factor not yet
  calibrated to match bridge domain)

Matiq fa71240d92 test: add validation harness (scripts/corpus.py + bridge baseline) to prevent Phase B regression 2026-08-21 01:06:05 +03:00
Matiq f17ee78061 docs: BITEXACT_PLAN — 8-step path to byte-parity; fix repo docs to reflect not-yet-bit-exact status 2026-08-21 01:00:41 +03:00
Matiq e990c21e94 fix: framed_test parse every comma band (was first-arg only); comb tests were single-band 2026-08-21 00:52:44 +03:00
Matiq b333f6828f docs: NOTES — verified comb params (neg sens, multi-mode); comb needs combine/acc, not params 2026-08-21 00:42:32 +03:00
Matiq 8e4e40b25a docs: NOTES — Pchip LUT fix + comb diagnosis (level-dependent, not multiband) 2026-08-21 00:34:18 +03:00
Matiq e5e9700333 fix: restore pchip LUT in framed_model (revert 12094f8 regression)
12094f8 replaced the empirical Pchip LUT with the parametric
linear form (CAP_A_LEVEL=-24/B=28/gamma=1). With gamma=1 the
parametric form reduces to identity on xv=log10(am/res), which
breaks the whole mask chain (t1kq fc-scan err jumps to ~7.9 dB).

Re-instating lut_pchip restores the honest baseline:
t1kq mean|err| 0.226 dB (was 7.9). Confirms NOTES_LEVEL F1
closure: no parametric LUT set beats Pchip at fixed bridge
params; the structural A/B/gamma (level-path ctx+0x188) is the
only real path to bytes, not this parametric substitution.
