The port flagged docs/re/data/boot-timeline-2026-08-29.tsv, whose label column
runs splash_dev before splash_pub, as a possible boot-order bug in its tree.
Three cold boots, t=0 at launch, no pad input, and the frames looked at rather
than only correlated: SQUARE ENIX 3.05-7.34 / 1.18-5.78 / 1.19-5.56 s, then a
~0.25 s black hold, then GAME ARTS/SETA/studio anima. Publisher first, 3/3.
The TSV is not wrong about any frame; its t=0 is ~7.7 s into the guest's boot,
so the publisher splash had been and gone before the stream opened. The tell is
in the file: its first twelve rows are byte-identical to four decimals -- one
held frame sampled twelve times -- and those exact numbers reappear in my run 1
at 8.42-10.94 s.
Second trap, new: ADV.wmv opens with its own SQUARE ENIX card, bloomed and below
centre, scoring 0.59-0.75 against live-splash-publisher.png. The classifier
fires splash_pub twice per boot and the second one is a movie frame. The real
splash holds perfectly still and scores 0.93-0.94.
And the dwells are DECODED, not measured: the publisher declares 240 units
(4.000 s) and the developer 195 (3.250 s), against measured 4.30/4.60/4.37 and
3.51/3.50/3.37. Measured over declared is 1.085 on average across six spans --
a 30 Hz timeline at 27.6 fps, which is the presentation rate this corpus has
measured independently three times. The port authors nothing here.
Instrument control run first: 11/11 content, 4/4 plate, the two splash
references rejecting each other at 0.035.
