+# Phase 2 Plan 01: HeatmapService, PHPUnit Tests, and API Endpoint Summary
+
+Data aggregation service querying t.date for timezone-correct daily grouping, JSON API controller at /heatmap/data, PHPUnit tests with mocked TimesheetRepository.
+
+## What Was Built
+
+1. **services.yaml** -- Added _defaults with autowire/autoconfigure, resource scanning for Controller/Service/Widget/EventSubscriber directories
+2. **HeatmapService** -- Queries TimesheetRepository grouping by DATE(t.date), sums duration, counts entries, filters by user/date range/optional project, excludes running timesheets
+3. **PHPUnit infrastructure** -- phpunit.xml config, bootstrap.php with dual autoloader path resolution (plugin root vs symlinked)
+4. **HeatmapController** -- GET /heatmap/data returning JSON with days array and range object, IsGranted auth
+5. **Controller test** -- Mocked service and user via container/token storage
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed bootstrap autoloader paths**
+- **Found during:** Task 3 verification
+- **Issue:** Plan's bootstrap paths used `../../dev/kimai/` from Tests/ dir, resolving one level too high
+- **Fix:** Changed to `/../dev/kimai/` (single parent from Tests/)
+- **Files modified:** Tests/bootstrap.php
+- **Commit:** 7060cfc
+
+**2. [Rule 3 - Blocking] Removed final from HeatmapService**
+- **Found during:** Task 5 verification
+- **Issue:** PHPUnit cannot mock final classes; controller test failed with ClassIsFinalException
+- **Fix:** Changed `final class HeatmapService` to `class HeatmapService`
+- **Files modified:** Service/HeatmapService.php
+- **Commit:** 7060cfc

+## Verification
