# Phase 7 Plan 1: Mode Switcher & Metric Toggle Summary

**Tabler nav-segmented controls for year/week mode switching and hours/count metric toggle, wired into HeatmapState with conditional stats rendering**

## Performance

- **Duration:** 2 min
- **Started:** 2026-04-09T09:14:18Z
- **Completed:** 2026-04-09T09:16:01Z
- **Tasks:** 1 (TDD: RED + GREEN)
- **Files modified:** 6

## Accomplishments
- Mode switcher (Year/Week) and metric toggle (Hours/Count) as Tabler nav-segmented controls with full ARIA support
- Controls wired into heatmap orchestrator updating HeatmapState and triggering doRender
- Stats row conditionally hidden in non-year modes
- Auto-scroll restricted to year mode only
- 11 new tests (73 total, all passing)

## Task Commits

Each task was committed atomically:

1. **Task 1 (RED): Failing control tests** - `cab07ee` (test)
2. **Task 1 (GREEN): Controls module + wiring** - `cd1ac52` (feat)

## Files Created/Modified
- `assets/src/ui/controls.ts` - createModeControl and createMetricControl functions
- `assets/test/controls.test.ts` - 11 tests for control rendering, click handling, ARIA
- `assets/src/heatmap.ts` - Import controls, wire to state, conditional stats/scroll
- `Resources/views/widget/heatmap.html.twig` - heatmap-controls div in card header
- `Resources/public/heatmap.css` - heatmap-week-cell cursor style
- `Resources/public/heatmap.js` - Rebuilt bundle

## Decisions Made
- createMetricControl reuses createModeControl internally, overriding className for nav-sm variant

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None.

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Controls are in place for 07-02 (week-mode renderer) to use
- WeekModeRenderer can be registered and will be dispatched when mode is 'week'
- Metric toggle ready for renderers to read state.metric for color scale selection

## Self-Check: PASSED

All 6 files verified present. Both commits (cab07ee, cd1ac52) found. All 11 acceptance criteria confirmed.
