Version 1.0: VLAW parameterization + detector cascade

- Implemented exact ln/exp2 infrastructure (log2_ln.hpp/cpp)
- Parameterized VLAW α/β/c by (fc, q, sens) configuration
- Implemented real RFFT for FIR construction
- Fixed VLAW parameterization for dual group (3.455 → 0.764 dB)
- Added detector cascade 529c60 (Haar smoothing, magnitude, peak processing)
- TOTAL error: 0.870 dB (vs bridge baseline 1.594 dB)

Results:
- t1kq: 0.618 dB (bridge: 0.226 dB)
- t1k: 0.938 dB (bridge: 1.801 dB) ✓ better
- al: 0.727 dB (bridge: 0.638 dB)
- res: 0.284 dB (bridge: 0.628 dB) ✓ better
- dual: 0.764 dB (bridge: 0.726 dB)
- comb: 3.000 dB (bridge: 10.149 dB) ✓ better

+### СЛЕДСТВИЯ (меняют понимание построения кернела):
+1. Перед EXP: бины 1..n/2 = −log(bands) ⇒ после exp = **1/bands** (обратная
+   величина!), бины выше = exp(0)=1. Экспонента применяется НЕ к спектру маски
+   напрямую — вокруг неё twiddle-FMA стадии (ops B/C/D = радиальные проходы
+   FFT-класса над упакованным вещественным спектром; buf548 = cos/sin таблица,
+   mask598 = lane-select).
+2. «×0.984» из 23d НЕ найден как константа цикла — либо внутри exp-IAT-обёртки,
+   либо следствие нормировки twiddle-стадий. Требуется численная репликация
+   пайплайна против живых захватов (rendersnap2 ph*.npz содержат готовые пары).
+3. Шаг 1 и шаг ×s888 — no-op при дефолтных параметрах (s888=1, live 24j).
+4. 52d920/52d990/52db50 = тонкие обёртки: 920→th2030/1d30 (scalar-op),
+   990→th2000/1c40 (axpy!), db50→то же. «УМНОЖЕНИЕ на окно» реализовано
+   axpy-кернелом, «деление» — scalar-op.
+5. Ops A–D работают над дескрипторными векторами (проверка тега [obj]==6 в
+   4ca80; ошибка 0xfffffff3 при несоответствии).
+
+### Динамика (попытки перехвата; окружение)
+- realtime-playback НЕ тикает DSP (нет аудио-девайса; треды спят в futex);
+  кривые 22y = результат инициализации при загрузке проекта
+- `-renderproject`: полный цикл init+render+exit хоста занимает ~0.8 c
+  (host@1.2s, workers@1.4s, wav@1.6s, exit@2.0s); обработка идёт в окне ~0.5 c
+- INT3-ptrace: SEIZE+TRACECLONE обязательны до CONT (иначе untraced thread
+  ловит SIGTRAP и убивает процесс — подтверждено); DR-брейкпоинты: DR0@user+0x380,
+  но POKEUSER DR7 даёт EIO. Скрипты: fntrace*.py, fnhw.py, fnall.py, firstop.py,
+  firtrace.py, hotips.py (см. scripts/)
+- Вывод: FUN_180529fe0 и 52d650/536300/52e260 НЕ ловятся в рендер-окне —
+  маск-цепь выполняется при ЗАГРУЗКЕ/изменении параметров, стационарный рендер
+  использует закэшированный кернел; либо трассировать надо момент инициализации
+- Выход плагина НЕдетерминирован: md5 двух свободных рендеров различен при
+  одинаковом rms (PRNG-дизеринг из LCG-прологов) — метрика только спектральная!
+
+## ДОПОЛНЕНИЕ 24t: ТОЧНЫЕ СЕМАНТИКИ СКАЛЯР-ОПОВ + опознание 563a60
+
+Инструмент: scripts/disasm_func.py (полный дизасм функции с резолвом
+RIP-констант инлайн).
+
+### Тела скаляр-трансформов (float-ветки):

+|---|---|---|
+| th2030→ffe0 | dst[i] *= scalar | scalar==1 → скип; ==0 → zero-fill |
+| th2270→14c40 | dst[i] += scalar | scalar==0 → скип |
+Оба: скалярный хвост + AVX2 основной цикл (vmulps/vaddps ymm). Двойные
+ветки (1d30/22a0) аналогичны на sd/pd.
+
+### FUN_180563a60 = init-time ПОСТРОИТЕЛЬ таблицы (не per-bin!)
+- Один caller: 1805636c2 (init-семейство).
+- Константы пролога: xmm11=8.68589 (20/ln10 — ln⇒дБ!), xmm12=1/1024,
+  xmm14=0.5, xmm10=2, xmm9=−1, xmm6=1; вызов IAT 181a14cd0 (log-класс)
+  над double из [obj+0x4198], ×8.68589 → дБ, запись пар во вектор
+  ([obj+0xe0], рост через realloc 56c640).
+- Вывод: строит дБ-доменную таблицу парами при param-rebuild — согласуется
+  с «LUT» ролью. Хвост с вирт. вызовом [rax+0x10] не декодирован.
+
+### Алгебра T1: обе формы фитуют серию драйва (8 точек недоопределены)
+- softplus α·ln1p(L/β)+c: rms 0.016 (α=3.2193 β=0.4927 c=0.542)
+- LUT-форма t=((dB−A)/(B−A))^γ·M: rms 0.029 (A=−36.2 B=20.0 γ=2.097 M=10.49)
+Различить только декомпом тракта am/res→scratch или бОльшим числом точек.
+
+### Открытые микровопросы
+1. Значение xmm7 на входе th2270 в FIR-цикле (52b5f6): трассировка от
+   52a583; если mix^p=1 → «bands+=1» противоречит провалам ⇒ xmm7 иной
+   либо порядок аргументов иной.
+2. Раскладка объекта-вектора (тег 6) для ops A–D.
+
+## ДОПОЛНЕНИЕ 24u: WIN_WINDOW движка — кусочное окно аудио-пути
+
+Таблица WIN_WINDOW[8193] (dsp/tables_data.hpp, live-захват):
+- [0]=0.500000, плавный подъём до [2048]=0.800000, затем СКАЧОК до 1.0
+  и единица до конца ([2049..8192]).
+- Длина перехода = РОВНО 2049 сэмплов = число бинов кернела (4096-сетка)!
+- Формула перехода не каноническая (ханн/синус/степенные не сошлись,
+  maxdiff ≥0.09); для репликации достаточно встраивания таблицы как есть.
+- Структура намекает: блок аудио 8192 сэмплов ({16384,8192} из cfg движка),
+  первые 2049 позиций получают взвешивание 0.5..0.8 (область «кернельного
+  взаимодействия»?), остальное прозрачно; 0.8 подозрительно = blend.
+Проверка употребления — в resize fe00 / audio-клее (следующий раунд).
+
+### Движок dc30: карта инициализаторов (24u)
+ctor 18052dc30 вызывает: 5335c0 (×2 — до/после валидатора), 534550 (×5 —
+регистрация конфиг-итемов, аргументы edx из стека [rsp+0x30..0x4c] =
+цепочка {2,4096},{16384,8192},{2,257}), затем ILT-стабы 2240/1c10.
+Следующий шаг декода: тела 534550/5335c0 + употребление WIN_WINDOW
+(по xref на таблицу или указатель из объекта).

+Формула тела подтверждена дизасмом: g=min(fc_norm/i,(fc_norm/i)^p);
+c=1/(1+g*tau/mult); up=exp(...); down=1-up.
+Эксперимент: одноразовый bidir с этими коэф. НЕ двигает центр кривой
+⇒ q-зависимость катов не через эти IIR напрямую; тракт между main-loop
+и scratch содержит ещё этапы (ops A–D / steps 9–19 BLOCKMAP).
+
+## ДОПОЛНЕНИЕ 24z: FUN_180563a60 ДЕКОДИРОВАН ПОЛНОСТЬЮ — ЭТО ДЕТЕКТОРНАЯ LUT-ФОРМА!

+Виртуальная альтернатива: [sub+0x90]!=0 → вызов [sub vtbl+0x10](A,B,dB)
+с клампом [0,1].
+⇒ ЭТО ТА САМАЯ ФОРМА, ЧТО ДАЛА ФИТ cut=LUT(A,B,γ,M)! Стадия компрессии

+ACC_i персистентен между кадрами ⇒ утечный интегратор: стационар
+ACC = input/(1−coef); усиление 1/(1−att): @43=2.57 @85=2.93 @171=3.42.
+Коэф. массивы СТАТИЧНЫ (∀ конфигов бит-в-бит — проверено dual/qmap/sens18).
+Гипотеза: резонансное усиление ACC объясняет k>1 аномалии уровней

+
+Следствие: если acc_i не накапливается сложением, «резонансная» гипотеза

+Если opB/opC сохраняют пропорциональность (упаковка real-FFT), то

+1802a24c0 относительно ln(bands): k = 1.760561/2 = 0.8802805.
+Альтернатива: k=1, а opB/opC суммарно дают множитель 0.88028.
+
+### Открытые микровопросы (следующий раунд, всё локализовано)
+1. Что такое [r15] на входе design (bands_final@678 или иной буфер)?
+2. Семантика opB/opC (th2180/th1bb0/th1a90/th19d0 + твидлы 548/550/598)
+   — вероятно упаковка/развёртка real-FFT.
+3. Масштаб выхода design: декод хвоста 1802a24c0 (файл уже есть:
+   nls_dasm/conv_float_a24c0.dis, 184K).
+4. Согласование с identity-фазой захватов (гонка финального combine).
+
+## ДОПОЛНЕНИЕ 24mm7: design выход = точный ln(bands_final); γ создаётся после design
+
+### Численный тест (multi6/ph034, identity-фаза)
+```
+scr@628 − ln(cur@678): max|r| = 9.0e-08 (float32 eps) на 1013 бинах
+⇒ k_design = 1 (в момент захвата)
+```
+Оговорка: станционарность делает «свежий» и «сталый» scratch
+неразличимы; но факт (scr, cur)=(лог, значение) одной пары твёрд.
+
+### Следствие для γ
+γ=1.760561 ≠ 2 ⇒ множитель НЕ только «×2 перед EXP». Источники:
+(a) opB/opC не взаимно сокращаются (не чистая упаковка real-FFT);
+(b) пост-exp шаги: окно 52d990 (варьируется по позиции — нарушил бы
+    степенной закон, значит действует на верхнюю половину/после),
+    pair-scalar th1880/th1ca0, финальный combine df0(FIR, track_i),

+= замкнулось. Затем перенос в C++.
+
+## ЗАДАЧА №2: параметризация α(контент)/fc
+
+α удваивается с числом тонов (частотное смешение шаблонно-локальное —
+далёкий тон не влияет, 24ll). Инструмент: scripts/campaign.py (ячейка ≈8 мин).
+Двухтональная дистанционная серия уже снята (sc_d*, инверсия не сошлась —
+нужен каскад из Задачи №1 сначала!).
+
+## СРЕДА (грабли, всё проверено болью)
+- rendersnap2.py: RENDER_FILE брать ИЗ rpp (клоны наследуют путь — однажды
+  перезаписали реф); каталоги снапов задавать уникальные (argv[3]).
+- touch+mtime перед каждым замером (same-second cmake hazard).
+- tone1k.wav громче dual.wav в 2.28× — при сравнении серий учитывать.
+- Свип НЕ годится для Y/X-отношения; только мультитон/мультиуровень.
+- Динамика V(t)↔g(t) на рампе не сходится — пары только из стационара.
+- HW-ловушки под wine невозможны (wine держит слоты); INT3 требует
+  дисциплины fnwatch4 и ГАРАНТИРОВАННО свежего рендера.
+- Метрика только честная: render_parity.load / Гёрцель последних 0.75 c.
+- Коммитить подшагами; факты → NOTES_LEVEL (очередной номер 24ll+).
