I claimed ptbtn00f's peak alpha of 80 was capture-only and refuted the
port's audit with it. Verified on the disc myself: ptbtn00f.rat, loop 120,
eight keyframes 0:0 6:6 29:74 35:80 50:80 58:74 97:6 105:0. ptbtn00 carries
TWO child records -- the leaf ptbtn00.rat (flat 255, which I read and
described correctly) and the focus record ptbtn00f.rat, which holds the
pulse. My "nothing declares 80" said only that nothing reached my
enumeration. METHOD.md has five entries on exactly this class.
Resolves the 🟡 with it: the corpus line attributing the 120-unit loop to
ptbtn00f is correct as written.
Turns the retraction into a stronger check. The amplitude is declared, so
check_labels.py now verifies the SHAPE: mean |alpha| error 1.14 levels (f6)
and 0.35 (f6b) against the declared 8-key curve. The first version assumed
the onset frame was t=0 and f6b FAILED at 3.24; the fix was aligning by
content rather than loosening the tolerance, since the 6->74 segment climbs
~6 levels per frame. Best lag is ~1 frame in both runs -- the element is not
drawn while its curve sits at alpha 0.
