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
