# Phase 01 Plan 05: Forest Screen & App Flow Integration Summary

**Forest overview with 6-level map (locked/current/completed states) and end-to-end app loop: welcome -> forest -> lesson -> forest with progress persistence**

## Performance

- **Duration:** 2 min
- **Started:** 2026-03-29T09:13:52Z
- **Completed:** 2026-03-29T09:15:39Z
- **Tasks:** 2 (1 implementation + 1 auto-approved verification)
- **Files modified:** 4

## Accomplishments
- Forest overview screen with level map showing 6 levels with locked/current/completed visual states
- Complete app flow wired: welcome -> forest -> lesson -> forest with automatic progress updates
- Level progression logic: completing a lesson marks level done, advances currentLevel, increments sessions
- Returning users skip welcome and go directly to forest with persisted state

## Task Commits

Each task was committed atomically:

1. **Task 1: Forest screen with level map and continue button** - `5bac850` (feat)
2. **Task 2: Verify complete Phase 1 app flow** - auto-approved checkpoint, no commit

## Files Created/Modified
- `src/forest/scene.ts` - Forest screen with getLevelStatus, renderLevelMap, initForestScreen
- `src/app.ts` - Rewired to integrate forest screen init, lesson completion handler, and navigation flow
- `index.html` - Added forest screen HTML structure with level-map container and continue button
- `src/styles/main.css` - Added forest layout, level card styles (current/completed/locked), continue button

## Decisions Made
- Forest screen re-initializes on every navigation (after lesson complete, after welcome) to ensure fresh progress state
- Extracted lesson completion logic into handleLessonComplete for cleaner flow
- startLessonFromForest reads keyboard layout from stored progress rather than threading it through as a parameter

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None

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

## Next Phase Readiness
- Phase 1 complete: all 5 plans executed
- Full typing exercise loop is playable from fresh start through level completion
- Forest screen ready for Phase 2 expansion (reward images, companion text)
- Progress persistence verified through re-init pattern
