# Phase 18 Plan 01: InitiativeHeader & ProgressPanel Summary

**InitiativeHeader with back navigation, status badge, and date metadata; ProgressPanel with task-based progress bar and phase/task counts**

## Performance

- **Duration:** 3 min
- **Started:** 2026-02-04
- **Completed:** 2026-02-04
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments
- InitiativeHeader component with ChevronLeft back button, initiative name h1, StatusBadge, and formatted created/updated dates
- ProgressPanel component reusing ProgressBar with phase and task completion stats
- Both components are pure presentational (no data fetching), ready for page assembly in Plan 04

## Task Commits

Each task was committed atomically:

1. **Task 1: Create InitiativeHeader component** - `62409a6` (feat)
2. **Task 2: Create ProgressPanel component** - `8cfc197` (feat)

## Files Created/Modified
- `packages/web/src/components/InitiativeHeader.tsx` - Header with back button, initiative name, status badge, created/updated dates
- `packages/web/src/components/ProgressPanel.tsx` - Card with progress bar and phase/task completion counts

## Decisions Made
- 18-01: Reuse SerializedInitiative shape for header props (dates as ISO strings, consistent with InitiativeCard)
- 18-01: Actions button disabled as placeholder — full actions dropdown comes in Plan 04

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Both components ready for page assembly in Plan 04
- Ready for 18-02-PLAN.md (next plan in phase)
