The port found its boot had no black frame between the publisher and developer splashes and authored 12 units by analogy with the menus' transition quad. On the boot path that analogy has nothing behind it -- palogo_eff0.prm is a single static keyframe, so the splash bundles declare no fade quad. I had agreed with the dismissal that hid the defect: told the residual was 0.03 s against a bound built from two measured ranges plus jitter slack, I said it said more about the bound than the game. The real gap was 0.2 s. Measured in the draw stream, which separates true black from a fade tail where luminance cannot: palogo_sqex is drawn to frame 125 at alpha 7, frames 126-129 submit NO sprite quad at all, and the developer fades in at frame 130 from alpha 34. Four presented frames, the only such run in the sequence. Converted with the disc as its own clock rather than a frame rate -- this run presented at 13.1 fps against 28 elsewhere -- palogo_sqex declares alpha >= 1 for 239.8 units and is drawn in 105 frames, giving 2.284 units per presented frame, which the title capture independently corroborates at 2.231. So the gap is ~9.1 units (0.152 s), against the 12 authored; +-1 frame is 6.9-11.4. And the true black is SHORTER, since both boundary frames still carry picture. Second finding: the developer splash is ONE composited 525x259 quad at the bounding box of its three declared logos, none of whose individual sizes is ever submitted. That is why an earlier pass reported "developer splash: 0 frames". Declaration sites ruled out: the splash bundles (no fade quad) and the top-level +0x08 (a family constant, 300/60, slack 12-226 units). The executable is NOT looked at and is named as the next place rather than claimed. Also answers the port's sweep question: +0x08 canNOT settle it, because ptloop01/ptloop02 have zero slack and a zero-slack record cannot distinguish "loops" from "runs once and stops". The oracle settles it for the TITLE -- the sweep oscillates over its whole range and resets hard to the same start, once in dwell 1 and twice in dwell 2, so it does not park. The MENU is unmeasured and stays open. Tooling: GRACE and NOTAP knobs for ui_draw_capture.sh. The script taps A on "the screen changed a lot", which is also true of a fading splash -- a first run tapped through the publisher and the developer never appeared. The instrument was perturbing what it measured. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QsEPXWVaEpyfudtR6re1Pd
