# Phase 3 Plan 03: Twig Template + Asset Serving Summary

**Wired d3 heatmap JS/CSS into Kimai dashboard widget via asset() helper and kimai.initialized event listener**

## Performance

- **Duration:** 2 min
- **Started:** 2026-04-08T11:19:31Z
- **Completed:** 2026-04-08T11:21:00Z
- **Tasks:** 4
- **Files modified:** 1

## Accomplishments

- Updated widget template to load heatmap.css and heatmap.js via Symfony asset() helper
- Added KimaiHeatmap.init() call with proper Kimai lifecycle event handling
- Installed assets as symlinks into dev Kimai instance
- Verified all tests pass (20 JS tests, 4 PHP tests) and build succeeds

## Commits

| Task | Commit | Description |
|------|--------|-------------|
| 1-4  | ac198ff | feat: wire heatmap JS/CSS into dashboard widget template |

## Files Created/Modified

- `Resources/views/widget/heatmap.html.twig` -- Replaced placeholder with asset loading, d3 heatmap init, and Kimai event wiring

## Decisions Made

- Use `kimai.initialized` DOM event for deferred widget init, with `kimai_context.javascriptRequest` check for AJAX-loaded dashboard panels

## Deviations from Plan

None -- plan executed exactly as written.

## Issues Encountered

None

## Next Phase Readiness

- Heatmap widget fully wired: template loads CSS/JS and initializes d3 visualization
- Ready for Phase 4 (integration testing with running Kimai instance)
