Quick curation pass: 0xa99->game_started (GAMESTART writer); 0x6be/0x6c3 ->ui-toggle (message-window render chrome), 0x6249e/0x204f4 ->unknown (gfx/field display state). Finding: high-scene-reach tail is dominated by shared render chrome, not story flags. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
