R1 (2026-08-03) closes F5 — no frame-indexed wavetables yet — deferring W1 with
"yet" preserved as scope rather than rejection, and confirming W3 out. Near-term
scope narrows to W0 alone. Cascades the consequences: F1's threshold amended
(static does not mean one-cycle, so detection classifies nothing now), F2
simplified, F3 and F7 firmed, F8 narrowed to a binary. F6/band-limiting left
open and explicitly not pre-ruled. PLAN.md item 4 updated to match.
Where the instrument's loop grid, crossfade and pitch handling stop making
sense as a capture shrinks toward one cycle, and what "wavetable synth" would
mean here. Two structural results: the pre-seam crossfade is the identity map
at one-period loop lengths, and YIN cannot detect a single cycle, so the period
is declared rather than detected there. Four candidate shapes, W3 recommended
out. PLAN.md gets a pointer under "Flagged for awareness" only.
