description: Implement maintainable Verse for a small UEFN gameplay slice. Use when a device-only solution is insufficient or existing Verse must change.

# UEFN Verse

Write the least Verse that makes the slice clear and maintainable.

## Rules

- Prefer existing Creative devices when they already express the behavior.
- Use Verse for orchestration, game state, rules, and gaps between devices.
- Keep one obvious owner for important state.
- Give functions one clear job.
- Prefer descriptive names over clever names.
- Prefer `@editable` for scene dependencies and designer-tuned configuration.
- Subscribe to events in an obvious setup location.
- Keep event handlers short; delegate meaningful behavior to named functions when it improves clarity.
- Log meaningful transitions when they are useful for debugging or proof.
- Compile after a small meaningful change.
- Do not invent APIs. Discover or verify current APIs when uncertain.
- Do not create architecture for hypothetical future features.
