Γ-W1-T5 remediation: narrow the rate-bound claim, fix baseline/measurement provenance, correct §2.4 framing
...
Re-derives the splice-cadence inequality and adds a corner probe that FAILS at
P=500 by design, pending a ruling. Names the baseline commit and harness edit,
fixes measurement methodology, corrects the Trigger-AHD/rate coupling framing.

Γ-W1-T5: a real Preserve time-stretcher — write rate is duration, tap rate is pitch
...
Generalizes the correlation-aligned SOLA delay line so the feed and the shift are
independent rates over one ring. Unity is bit-identical to the shipped read, asserted
against a hash baseline captured pre-change.

Q-W0 code-review remediation: pitch_shift follower self-heal, T3-03 rate bail, doc/comment riders

fix(q-w0): six audit fix-nows — linked-lag stereo SOLA, playable-span prime bound, declick dead-state, provenance cursor hardening, rate-derived gain ramp + fade ceiling

fix(pitch_shift): re-anchor fadePos_ on freeze so gNew is continuous at the freeze frame; guard left cast; add step-detector + loop-never-freezes regression

fix(preserve): GA3 tail wind-down — freeze the SOLA writer at source exhaustion so the tail recycles frozen real content (no DC-splice chop through the final window + release)

fix(preserve): clamp Preserve feed to real-content bound at tail; lock sub-sample refinement with non-integer f0; fix stale onset-latency doc + clamp comment

fix(preserve): prime SOLA rings with real source (zero-latency, gap-free onset) + sub-sample splice alignment — clean repitch C1..C8

test(pitch_shift): tighten purity f0 to 1/196 so revert-of-fadeLen_ fails; add hop guard; clamp fadeLen_ in double before int64 cast

fix(pitch_shift): ratio-scale splice fade so +24st up-shifts never read stale data; normalize SOLA correlation by candidate energy; tests bracket 4x/0.5x + unity/latency asserts

fix(preserve): correlation-aligned splices replace dual-tap OLA — fixed w/2 tap offset anti-phase-cancelled crossfades (beating/partials on repitched sines); spectral-purity test added

Per-zone play params on SampleData; hand-rolled pure pitch_shift OLA for Preserve (WDL drags
windows.h); zone-payload v3 tail; RT-safe pre-warmed shifters + Preserve voice cap.
