There were TWO splash screens and this port had neither. Entries 11/14 are the developer logos; entries 10/13 are the SQUARE ENIX publisher wordmark, the first thing the boot shows, which nothing in this project had noticed. They have no .rat layout child so `is_build` cannot see them, and the RE agent established that no CONTENT rule can either: design size fails (every extra composable bundle sampled is 1280x720, same as every screen) and element count fails (fragments run 2..15 elements in GP_OPTIONS/GP_SAVE_LOAD, the splash halves are 3 and 7 -- the ranges overlap). So `screen_builds` is `is_build` plus an authored allow-list of ENTRY INDICES, each carrying a `why` that says it is a locator and not a claim. An allow-list rather than a loosened predicate because this is safe in GP_TITLE and would not be in general: there, widening adds exactly four bundles and all four are real screens, zero fragments. screen_names.json is rekeyed from enumeration ordinal to pak entry. Widening renumbers ordinals, and a name that moves when the enumeration rule changes is not a name -- the file always called the entry the stronger locator, and it is now the only stable one. The two unnamed plates therefore renamed build_10/11 -> build_12/15; they were always locators, and now they locate the right thing. All 16 export and validate.
