# Phase 7 Plan 02: Week Mode Renderer Summary
|
|
|
|
**WeekModeRenderer aggregates time entries by weekday into 7 horizontal SVG cells with color scale, metric toggle, and weekStart-aware ordering**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 4 min
|
|
- **Started:** 2026-04-09T14:29:19Z
|
|
- **Completed:** 2026-04-09T14:33:19Z
|
|
- **Tasks:** 1 of 2 (Task 2 is human-verify checkpoint)
|
|
- **Files modified:** 3
|
|
|
|
## Accomplishments
|
|
- WeekModeRenderer implements ModeRenderer with aggregateByWeekday logic summing hours/count per weekday
|
|
- 7-cell SVG with color scale from buildColorScale, empty cells get heatmap-empty class
|
|
- Tooltips show full weekday name with hours-first or count-first format depending on metric
|
|
- Labels respect weekStart preference (Monday-first or Sunday-first ordering)
|
|
- Registered in heatmap.ts for dispatch via mode switcher
|
|
- 14 tests covering aggregation, rendering, tooltips, empty state, label ordering
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1 RED: Failing tests for week renderer** - `7fba98f` (test)
|
|
2. **Task 1 GREEN+REFACTOR: Week mode renderer implementation** - `9dde529` (feat)
|
|
|
|
## Files Created/Modified
|
|
- `assets/src/renderers/week.ts` - WeekModeRenderer with aggregateByWeekday, 7-cell SVG, tooltips (149 lines)
|
|
- `assets/test/week.test.ts` - 14 tests covering mode, rendering, aggregation, tooltips, labels, destroy (178 lines)
|
|
- `assets/src/heatmap.ts` - Added WeekModeRenderer import and registration
|
|
|
|
## Decisions Made
|
|
- Labels placed centered above each cell in horizontal layout rather than in a left column, since the 7-cell week view is a single horizontal row
|
|
- Used synthetic DayEntry array from non-zero aggregates to feed buildColorScale, keeping color domain based on actual data values
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
None.
|
|
|
|
## User Setup Required
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- Task 2 (human-verify checkpoint) pending -- requires visual verification in running Kimai instance
|
|
- Week mode renderer is code-complete and all tests pass
|
|
- Ready for day-mode renderer (phase 08) once visual verification confirms correctness
