Why

MIAU sometimes appears to walk backward because bundled packs supply the built-in 🐈 as a plain palette string, which currently suppresses its known native facing. The face direction should be defined by the glyph and follow successful horizontal travel consistently across proofs.

What Changes

  • Declare 🐈 as a native-left directional glyph for built-in MIAU, including bundled packs that repeat the same glyph as a plain string.
  • Set horizontal facing from successful displacement, including a push, while preserving it through vertical movement, idle frames, and blocked input.
  • Keep an unrelated mod glyph non-directional unless its palette object declares faces.
  • Verify proof, Title, INDEX, Undo, reset, mod palette, and mobile rendering.

Capabilities

New Capabilities

None.

Modified Capabilities

  • game-presentation: make native MIAU facing and successful travel the authority for horizontal glyph orientation.

Impact

Canvas glyph orientation, presentation movement history, mod palette interpretation for the built-in cat, browser verification, and the design handoff. No simulation coordinates or mod file format change.
