Conversation
The two engine rings sit in the trail state struct at +0xC0, the across/side normals share one workspace and the second vertex loop sets its position pointer in its own initializer: 1,188/1,188 bytes, no flags or barriers. Full build 1224/1224 exact; progress/report.json regenerated. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

func_0022F738insrc/game/space.c, the space flights' engine-trail ribbon builder (1,188 bytes), is now C and matches exactly: the 0x210-byte frame, every instruction, and the 4 alignment bytes after it. There are no new flags, inline assembly, register pins or barriers.What closed the last differences (from a 62-byte near miss):
D_0013E130, so they still live at 0x0013E1F0 / 0x0013E3F0. This changes which address expressions GCC shares, and gives retail's order of the cross-product calls.forinitializer, after the first draw, which gives retail's setup around that draw.Checks
