# Phase 10: Events Plan 03 Summary

**Events month navigation, day prefill, overflow display, and user-scoped planning query**

## Performance

- **Duration:** ~15 min
- **Started:** 2026-05-15T22:47:00Z
- **Completed:** 2026-05-15T23:02:00Z
- **Tasks:** 2
- **Files modified:** 5

## Accomplishments

- Added tests for month navigation labels, day prefill, submitted-date precedence, overflow display, and user-scoped aggregation.
- Added `ListUserEventsRange` joining events to tablos and filtering by `tablos.user_id`.
- Added human-readable previous/next month labels to the Events calendar view model.
- Confirmed day-cell create prefill, POST field precedence, and `+N more` overflow behavior.

## Task Commits

Each task was committed atomically:

1. **Task 1: Add RED coverage for navigation, prefill, overflow, and aggregation** - `0692dd2` (test)
2. **Task 2: Implement navigation, day prefill, overflow display, and planning query** - `ebd31b5` (feat)

## Files Created/Modified

- `backend/internal/db/queries/events.sql` - Adds the user-scoped date-range aggregation query.
- `backend/internal/web/handlers_events_test.go` - Adds navigation, prefill, overflow, and aggregation tests.
- `backend/internal/web/handlers_events.go` - Adds previous/next month label data to the calendar model.
- `backend/templates/events.templ` - Uses human-readable month labels in accessible navigation.
- `backend/templates/events_forms.go` - Extends `EventsCalendar` with previous/next month labels.

## Decisions Made

- Query `date` is only a GET default for opening the create form; create and update persistence reads submitted form fields.
- The planning query returns owned events across all tablos with `tablo_title` and nullable `tablo_color`.

## Deviations from Plan

None - plan executed as written.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

The Events tab behavior and the planning query handoff are ready. Plan 10-04 can focus on regression coverage and final verification for Phase 10.
