ui-resting-pose.md built its dwell-fallback section on GP_TITLE build 7's ptlogo_eff3.t32, listing keyframes [46, 61, 103, -] -- the STALE PARSER's output. Corrected they are [0, 46, 61, 103], the longest gap moves from 61->103 to 0->46, and BOTH ends of the new longest gap are a=0. The element no longer selects a visible pose under either indexing, and build 7 renders byte-identical under the corrected and legacy readings (0 px differ). MISSION lists this element as the one case a Japanese capture was needed to discriminate; it is not. But losing an example is not closing a question, so: disc-wide census. The fallback fires on 2 305 of 13 991 elements and returns a VISIBLE pose in 1 697 of them -- 74 %. GP_TITLE is 5 fires, 4 visible, and all four are on the SPLASH screens: palogo_sqex_eff and palogo_anima_eff, each [0:a0 15:a255 30:a212 45:a0], a flash peaking at 15 and dead by 45 where the fallback returns t=30 a=212. Independently converged on from the other side: the port, working from the JP capture and knowing nothing of this census, found ptlogo_back2eff1's rest.t at the peak of its own 4-unit sparkle with six staggered across the logo, so --pose=rest fires every sparkle at once -- a frame the game never shows. Consequence recorded as a rule: a render posed at rest is a legitimate common reference for comparing two DECODERS and is not a frame to score against a capture of the game.
