`title` is the port's largest disagreement with the oracle at 1.82%, and last iteration I attributed it to the moving ptloop sweeps without checking. Wrong, and so were the two hypotheses I formed after it. NOT THE SWEEPS. ptloop01/02 are 399x180 at (441,270) -- small and central -- and their exported keyframes hold pos, scale and rotation constant. The difference peaks at x~1088. NOT AN OVER-HELD ELEMENT. Added `--no-hold` to render the alternative: playing the title's groups past rest fades the screen to black by t=5.2 s, 30.97% differing against 1.82% held. Holding at rest is right. NOT A TIMING OFFSET. Sweeping the build-in gives 24.05% at t=1.6 falling monotonically to 1.68% at t=4.18 and 1.82% settled. The capture is at the settled end. WHAT IT IS: a horizontal redistribution. Signed difference by cell shows the port DARKER centre-left (-13.1, -8.3, -6.6) and BRIGHTER right (+16.0, +9.9), nearly cancelling -- whole-frame means 63.8 against 62.5. Brightness in the wrong place, not a level error or a tone ramp. It falls in the rows spanned by the two wide elements ptlogo_back2 (1118x262) and ptlogo_back2eff (1133x280), with the column profile falling off past x~1152 against their right edges at 1189 and 1197. AND THE EXPORT CARRIES NO BLEND MODE. ptlogo_back2eff's keys are declared, id, index, keyframes, kind_raw, layer, layer_source, pivot, rest, role, sprite -- there is no blend field, in this element or in FORMAT.md at all, and the port composites everything with normal alpha. If the game draws `_eff` layers additively, a wide gradient sprite would produce exactly this signature and nothing in the export would reveal it. Asked, not assumed; I have not tested it, and I am recording it because the three I could test are dead. Recorded and NOT acted on: pteff02's rest.t is 46, where its fade is 25% black, while its own group reaches 0x00000000 at t=236 -- so the port holds a black veil the timeline removes. Third instance of rest.t naming a hold that is not the settled state. It does not explain the residual: removing a darkening veil would make the port brighter still, and it is already brighter where it disagrees. `--no-hold`'s first version set the flag thirty lines before `view` exists and silently rendered nothing, caught because the loop found no files rather than because anything reported an error.
