+**Universal packed resource addressing confirmed (2026-07-21).** `asset_catalog_parse_base_tables@0x44e7e0`
+parses one entry count and copies one flat array of 0x50-byte SYS4INI records in serialized order.
+`asset_open_indexed_entry@0x44f390` directly bounds-checks a high-byte-zero operand against that count and
+indexes `entries[id]`; a nonzero high byte takes the AAI branch described above. It receives neither
+`EngineCtx` nor a script-frame/scene identifier and contains no section-base calculation or fallback.

+The callers pass their operands unchanged: `script_frame_load_resource@0x40e980`,
+`gfx_op_0x1f9_load_surface@0x422360`, `op_0x249_load_raw_texture_surface@0x424b20`,

+`movie_to_texture_open_asset_graph@0x463e20`. For movies, `op_0x236_play_movie_to_surface@0x423ee0`
+fetches operand 1 and immediately forwards it to that helper. Thus scene-local and raw-fallback are not
+native modes: ordinary resource operands are already universal packed SYS4INI/AAI ids.

+SC0010 supplies a clean corpus proof outside SC0000's base-zero coincidence. Its `set-texture 0x21` must
+open raw entry `0x21` (`SO013A.AGF`); adding SC0010's catalog position `0x11e` instead selects unrelated
+`COL0023.OGG`. Its `play-voice 0x120/0x121/0x122` operands directly select
+`LILA1414/LILB0053/LILC0054.OGG`, whose SC0010-local file numbers are 2/3/4. The catalog grouping relation
+is therefore `absolute id = group start + file_number`; the compiler has already performed that addition.
+The port's scene-first compatibility resolver inverted this relationship and must be replaced by typed
+`ResolvePacked` lookup for texture, voice, and movie consumers. Ghidra `/v2` renames the catalog parser and
+entry-name helper, corrects the opener/caller comments, and is saved.
