WHAT I WANTED FROM IT: 56cc7ac, "a RATC child's name is stated, not inferred". A child was named by scanning backwards for the last printable run of bytes before its magic. For `pteff05.t32` the three trailing payload bytes are 38 41 58 = `8AX`, which beat the real name, so the child registered under a name no element declares and resolved to no sprite. `pteff05.t32` is the full-resolution background of all five menu screens. Every menu render this port has produced has been missing its background, and P1 wrote that up as a fact about the disc -- "the bundle carries zero RATC children for either, so there is no texture on the disc to export". That is retracted in docs/DECISIONS.md rather than edited away. The re-export is contained: six new sprites and nothing else. pteff05 on main_menu/extras and their JP twins, pteff04 on both titles. Each gains a `sprite` line and moves `layer_source` from "implied" to "sprite" -- the layer key is now read from the file instead of the decoders' table of keys measured off the running game, which is the ratchet turning the right way. pteff05.png is 1280x720; ptbase.png, which had been carrying the background alone, is 640x360 drawn at 200 %. Measured against the live capture rather than the other renderer: settled main_menu RMSE 8.05 % -> 5.92 %. The reference renderer was missing the same element for the same reason, so no renderer-vs-renderer diff could have found this -- the third time a capture has caught something both renderers agreed on.
