fix: corpus 24-bit loader + LUT calibration env var
...
- Fix reshape error in corpus.py 24-bit WAV loader (misaligned data)
- Add RT_LUT_CAL env var for LUT output calibration
- Corpus results: TOTAL 2.397 (bridge 1.594), comb improved (-4.032)
- Structural chain regresses on t1kq/t1k/al/dual due to LUT curve mismatch
- The LUT produces different frequency response than plugin's FIR construction

fix: persistent IIR state eliminates ×1.805/×2.44 gaps
...
Root cause: IIR accumulator reset to 0 every frame, losing temporal state.
Fix: static thread_local accumulator persists across frames.
Results (dual_b1q_0.5, reaper render):
cut@500 = -10.32 dB (EXACT match, was -14.35)
cut@2000 = -11.82 dB (EXACT match, was -6.58)
Both the ×1.805 (OLA normalization) and ×2.44 (mask computation) gaps
were caused by the same root issue: IIR state reset.

feat: ×1.805 confirmed — OLA normalization factor (24i)
...
Steady-state simultaneity test: 60 captures, mask constant at 0.5099,
fir constant at 0.5241, actual cut -10.32 dB.
Ratio actual/fir = 1.839 ≈ ×1.805 from 23e/24e.
Two independent error sources identified:
1. Mask computation: 0.209 vs 0.510 (×2.44, LUT issue)
2. Application: per-bin vs FIR convolution (×1.805, OLA)

feat: consumer identified (th_b3c0), scan3.py, RT_FIRCONV/RT_FIRPOWER
...
- th_b3c0 (0x18000b3c0) = pure complex multiply FIR × audio in freq-domain
- scan3.py: pre-scan approach finds ctx in 1.5s, multi-instance detection
- RT_FIRCONV=1: FIR from mask + complex multiply (spectral.cpp)
- RT_FIRPOWER=1: power-law mask from raw spectrum (framed_model.cpp)
- Root cause: plugin uses FIR convolution (OLA), not per-bin multiply
- Live captures: FIR@43=0.524, mask@43=0.510, final gain=0.305
- Best result: RT_LUT_OFF gives cut@500=-8.18 dB (ref -10.32)
- NOTES_LEVEL 24e/24f/24g appended
