A path that names its own archive is a free name->key fact, since a pak TOC holds only hashes. Swept them disc-wide and aimed the result at the 2D / GP_READY_ROOM blocker. Seven fields carry a game: value - BackGroundPackage 18, StageResourcePackage 23, TBL_3D 6, LodEnumTable 7, MotionEnumTable 7, one PATH, one anonymous - giving 63 distinct paths in two forms: 42 file-form (41 present on the extracted ISO, the single miss being the bare directory game:\hidden\Resource3D\, which is not a file) and 21 archive+entry (20 of 20 resolve inside the archive they name; the 21st is sound.pak+ with an empty entry). The blocker test is a measured zero. The six 2D paks and GP_READY_ROOM hold 1817 distinct keys between them and NONE is named by a + path. The dictionary's total reach is 20 of 16630 keys, 0.12%, and every one lands in DefTables or GP_HANGAR_ARSENAL - archives that are already partly named. The route is exhausted rather than unlucky: these paths exist only in the seven fields above, and none of those fields ever addresses a 2D or ready-room asset. The blocker keeps its earlier structural reason (six identical 711-key TOCs, 0 of 711 shared with any other archive). The full dictionary is recorded: 6 x <lang>\GP_HANGAR_ARSENAL_3D.tbl in GP_HANGAR_ARSENAL.pak, and EnumGameModel_* plus EnumLODSet_* for S24, S26, S27, S28, S29, Tutorial and test in DefTables.pak. Left unexplained: both DefTables families are seven names with S25 absent and no story stage present at all. All fifteen artefacts byte-identical.
