Swept all 19 StageResource fields by value kind. Refuted: <X>ID + <X>Package is not a convention. The record has exactly one *ID field (BackGroundID) and exactly one pairing stem. StageResourcePackage has no StageResourceID; WingmanIconID_0..3 have no package. n = 1 is not a rule, so last pass's generalisation is withdrawn. Fourth kind - the game:\ external path. BackGroundPackage (18 values) and StageResourcePackage (23) are neither records nor pak keys because they are ISO file paths. Mapping game:\ to the extract root and \ to /, case-folded, 41 of 41 exist on the extracted disc (hidden/resource3d/BG_Acheron.xpr, Stage_S01.xpr, ...; 166 .xpr files in that directory). Fifth form - game:\hidden\<archive>.pak+<entry>. LodEnumTable, MotionEnumTable and TBL_3D name an archive AND an entry inside it, e.g. game:\hidden\DefTables.pak+EnumLODSet_S24.tbl. Splitting on + and hashing the right half against THAT archive's keys resolves 20 of 21; the one failure is sound.pak+ with an empty entry name. Some of those entry names carry an explicit <lang>\ prefix (deu\GP_HANGAR_ARSENAL_3D.tbl, eng\, esp\), each present in 0 other archives, so the language-prefix form is genuinely used by the engine. This does NOT unblock the 2D naming problem: archive-naming refuted <lang>\ there structurally, since the six 2D paks share one identical 711-key TOC and cannot carry per-language names. Both facts stand. The 4 never-shipped _Test tables - the residual of the 344-name census - are now named: EnumCharacter_Test.tbl, EnumLocalString_Test.tbl, EnumSquadron_Test.tbl, StageMessageSet_test.tbl (lower-case test on the last). WingmanIconID_1..3 hold PGHUD_WING2/WING3/WING4, HUD element names from the PG* roster; WingmanIconID_0 is never valued. All fifteen artefacts byte-identical.
