Refutes a DECISIONS claim and decodes the element the port withheld on my say-so. The claim that title_jp s ptlogo_eff2 at 125 percent is the single drawn element in the whole export at a scale that is not a whole multiple of 100 percent rested on a census of PARENTS only. Opening the 45 leaves as well finds thirteen distinct non-whole-multiple scales -- 75, 96, 99, 101, 103, 112, 125, 150, 204x208, 210x220, 250, and the 75x100 / 96x100 / 99x100 pairs -- with 125 among the rarest at two occurrences. ptlogo1 and ptlogo2 carry 101/103/112 on the ENGLISH title too, so it is not a Japanese-build peculiarity. The claim s real content was "the only one the port draws", which is about the export s element set rather than the disc. And ptlogo_eff2 is decoded. The 125 percent lasts 57 units, about 0.95 s -- a scale-0 to 125 to scale-0 flash between t=50 and t=107, a transient rather than a steady state, which is why it looked anomalous in a census of resting poses. The leaf draws at 100 percent as two superimposed copies of the same sprite at alpha 160 and 80, each rotating a full 360 degrees over 960 units: a slow double-layered spin, 16 s per revolution. This is exactly the case the ptloop rule could not separate. There the parent had expired so leaf-wins and parent-ignored were indistinguishable; here the parent carries real geometry including a scale that reaches zero twice. If parent scale gates the leaf the spin is a 0.95 s flash; if the leaf runs on its own timeline it spins for 16 s. Nothing on the disc chooses between them, and title_jp has no oracle capture, so it is undecodable in this container -- the port is right to withhold it, and the Japanese-locale capture MISSION has parked would settle it.
