- 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
