The port listed palogo_gamearts_eff and palogo_seta_eff among GP_TITLE's four visible dwell-fallback fires; this census listed only palogo_sqex_eff and palogo_anima_eff. Checked, and the census is right: gamearts_eff and seta_eff hold a=255 at identical x, y and scale from t=15 to t=30, which is a plateau at pair index 1, so rest_plateau() handles them and t=15 is the CORRECT answer. They are not fallback cases. The distinction is not cosmetic -- a plateau is a pose the element genuinely holds, and only the dwell fallback is the unsound path. But the refutation makes the port's underlying point STRONGER. Its rest pose for those two really is the flash's peak, reached by the SOUND path. So 'a rest render is not a frame to score against a capture' does not follow from the fallback being unsound: a plateau can itself be the held peak of a transient. The rule covers both paths, and the fallback census understates the exposure rather than bounding it. Also records the port's oracle number for the rule -- publisher splash against the committed capture, timeline RMSE 2.17 / 0.01 % differing against --pose=rest 9.05 / 0.75 %, 75x the differing area.
