Decodes the last unidentified entry type in graphics.dat: cls = (1, 0, 7, 0x0A) is the V4 engine's global creature animation frame table (tblCreatureFrameInfo14 / _4976_5a98), loaded from this exact GDAT entry by SKWIN/SkWinCore.cpp:54795-54796 and consumed per facing direction by QUERY_CREATURE_PICST.

  • dm2_graphics::CreatureFrameTable / CreatureFrame typed decoder + Archive::creature_frame_table()
  • tests/creature_frame_fixture.rs pins the 8-port byte identity (all Japanese-lineage archives), the 8-port absence (all Western V5-lineage archives), the 118-frame decode, and per-field invariants
  • graphics-dat.md § "Slot 0x0a" documents the 14-byte record layout and engine references; ROADMAP entry checked off with the corrected distribution (the record is a V4-lineage marker, not console-only)

Full investigation details in the issue comment.

Closes #266
