# Phase 10: Events Plan 04 Summary

**Final Events regression coverage, full backend verification, and approved browser UAT**

## Performance

- **Duration:** ~10 min
- **Started:** 2026-05-16T04:35:00Z
- **Completed:** 2026-05-16T04:45:10Z
- **Tasks:** 3
- **Files modified:** 1

## Accomplishments

- Added final handler regression tests for full-page fallback, escaped event titles, no-end-time behavior, and same-day ordering.
- Ran full backend verification with generated code.
- Started the local app for the browser checkpoint and received user approval for Events UAT.

## Task Commits

Each automated task was committed atomically:

1. **Task 1: Add final regression coverage for tab integration and escaping** - `1d760d5` (test)
2. **Task 2: Run full backend verification and fix regressions** - no code changes required
3. **Task 3: Browser UAT checkpoint for Events tab** - approved by user on 2026-05-16

## Files Created/Modified

- `backend/internal/web/handlers_events_test.go` - Adds final Events regression coverage.

## Decisions Made

- Verified the no-end-time behavior through edit-form output rather than calendar cells, because Phase 10 explicitly keeps calendar cells title-only.
- No implementation fixes were needed after full backend verification.

## Deviations from Plan

None - plan executed as written.

## Issues Encountered

- `just dev` could not bind to ports `8080` or `8081` because they were already in use. The browser checkpoint server was started on `8082` instead, then stopped after approval.

## Verification

- `cd backend && TEST_DATABASE_URL='postgres://xtablo:xtablo@localhost:5432/xtablo?sslmode=disable' go test ./internal/web -run 'TestTabloDetailEventsTabFullPageFallback|TestEventContentIsEscaped|TestEventWithoutEndTimeDisplaysOnlyStartTime|TestEventsOrderedByStartTimeThenTitle' -count=1`
- `cd backend && just generate && TEST_DATABASE_URL='postgres://xtablo:xtablo@localhost:5432/xtablo?sslmode=disable' go test ./... -count=1 && git diff --check`
- Browser UAT approved by user.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

Phase 10 is ready to close. Phase 11 can consume `ListUserEventsRange` to build individual planning across the user's tablos.
