# Quality Checklist: Pane Panel Spinner Animations

**Change**: 260416-a5ug-pane-panel-spinner-animations
**Generated**: 2026-04-16
**Spec**: `spec.md`

## Functional Completeness
- [ ] CHK-001 BrailleSnake component: Exists at `braille-snake.tsx` with correct frames and interval
- [ ] CHK-002 Agt line spinner: BrailleSnake renders before agent state text in status-panel.tsx

## Behavioral Correctness
- [ ] CHK-003 BrailleSnake animates: Frames cycle `⣾⣽⣻⢿⡿⣟⣯⣷` at 80ms
- [ ] CHK-004 BlockPulse unchanged: Run line still uses BlockPulse with `░▒▓█▓▒` at 150ms

## Scenario Coverage
- [ ] CHK-005 Agent state present: Agt line shows `agt ⣾ {state}` with spinner animating
- [ ] CHK-006 No agent state: No agt line rendered, no BrailleSnake mounted

## Edge Cases & Error Handling
- [ ] CHK-007 Unmount cleanup: BrailleSnake clears interval on unmount (no memory leak)

## Code Quality
- [ ] CHK-008 Pattern consistency: BrailleSnake follows same structure as BlockPulse (useState + useEffect + setInterval + span)
- [ ] CHK-009 No unnecessary duplication: Spinner components are separate files, not a shared generic with config

## Notes

- Check items as you review: `- [x]`
- All items must pass before `/fab-continue` (hydrate)
- If an item is not applicable, mark checked and prefix with **N/A**: `- [x] CHK-008 **N/A**: {reason}`
