nx_manga_charsheet_gate.nx

nx_manga_charsheet_gate.nx -- REFEREE for R4 (nx_manga_charsheet). END-TO-END: builds its own mesh by forking nx_body_gen, writes its own sheet specs, forks the PROMOTED sheet elf, and reads the artifacts back off disk. It measures the shipped binary, not a convenient in-process copy of the logic. It proves the DONE-RULE pre-declared on /compare/mangagen before the organ existed: "Legality-checked pose sweep, renders, sheet grid; identity judged per cell." NEGATIVE CONTROLS, because a green that never had a red is unverified: neg-control-white -- the ink counter must return ZERO on a blank buffer, so the drew-something teeth cannot pass on any image at all. neg-control-nomesh -- an unreadable mesh must REFUSE and leave no sheet. neg-control-hole -- a view the renderer cannot satisfy must REFUSE, because the whole point is that a sheet is never composed with a hole in it. license_tier: ORIGINAL expect_exit: 0
