STFT partitioned conv: FIR construction pipeline (52b550-52b8bb)
...
Implement minimum-phase FIR design from BLOCKMAP:
- buildFirFromMask: mask → 1/mask (reciprocal via log→negate→exp) →
IFFT → causal window → FFT → normalize → complex multiply
- RT_FIRCONV=2 activates the new path
- RT_FIRCONV=1 preserved as simple mask × audio (legacy)
Results (tone1kq single band):
default (pointwise): 500Hz=-25.35 dB, 1kHz=-50.60 dB
FIRCONV=1 (mask mul): 500Hz=-1.31 dB, 1kHz=-25.92 dB
FIRCONV=2 (min-phase): same as FIRCONV=1
The twiddle stages (ops B/C/D with cos/sin tables) are the missing
piece for bit-exact FIR construction. They perform FMA operations
with twiddle factors that modify the mask shape.
Note: dual_b1q_0.5.wav reference is empty (0 bytes) — corpus can't run.
Needs regeneration.

cascade integration: sin-peak floor, complex twin resp storage, per-band cascade
...
- Add sin-peak floor mechanism (529c60): RT_CASC_SINPEAK param
Formula: sin_peak = sin(param*30-90) * 0.115129 * peak_level
Floor active for param in [3,9], max at param=6 (ln10/20=0.115129)
Prevents over-reduction by clamping level curve from below
- Store complex twin filter responses in FramedDetector::setParams()
for cascade 529c60 per-band processing
- Add cascade state persistence (fn529fe0::CascadeState per band)
- ctx[0x24] = 48000 (sample rate, from commit 0e90918
