daniel f1168e16eb Close Γ-W1-T7 re-review: pitch-sync cadence math, floor-model regression check, evidence-count fix, one-home comments 
New cadence-collapse-band test at P=1470 shows PSOLA eliminates the corner rather than regressing it (18.52% -> 0.00%).

daniel 93230208ff Γ-W1-T7: make Preserve's splices pitch-synchronous — the jump is a whole number of the source's own period, detected once at load 
30 Hz out-of-band energy 15.45% -> 0.00%; the 29 Hz rate-2.0 detune -133 -> +0 cents.
An unknown period keeps the fixed-window geometry bit for bit. The detector cannot
reach process(): sampler_core does not link it.

daniel ac653aa581 Measure Preserve's splice-alignment geometry on low-frequency material 
A splice can only relocate by [0.75, 1.25]*window, so periods with no multiple
in that interval never phase-align — at 50 ms, f < 16 Hz and 26.7-32 Hz.
Harness runs by hand; too slow to gate.
