+# Phase 03 Plan 05: Parent Area Summary
+
+**Code-gated parent area with stats overview (level, sessions, accuracy, calendar dots, error keys) and settings panel (layout, audio, companion, API key) persisted via IndexedDB**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-03-29T11:44:19Z
+- **Completed:** 2026-03-29T11:46:30Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+- Parent area accessible via Ctrl+Shift+E with code gate requiring "1234"
+- Stats overview showing current level, total sessions, accuracy percentage, 30-day calendar dots, top 5 error keys
+- Settings panel for layout, audio, companion, and API key with immediate IndexedDB persistence and "Gespeichert!" feedback
+- Back button returns to forest screen
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Parent area HTML, CSS, and access gate** - `44c28fe` (feat)
+2. **Task 2: Wire parent area into app.ts** - `a5326c7` (feat)
+
+## Files Created/Modified
+- `src/ui/parent.ts` - Parent area module with code gate, stats rendering, settings management
+- `index.html` - Parent screen HTML with gate overlay, stats grid, settings form
+- `src/styles/main.css` - Parent area styles (stats grid, calendar dots, error badges, settings)
+- `src/app.ts` - Import parent module, register Ctrl+Shift+E listener, init parent screen
+
+## Decisions Made
+- Access code hardcoded as "1234" -- single-user private app, no need for configuration
+- Settings use immediate save on change with inline "Gespeichert!" feedback that fades after 1.5s
+- Calendar dots show last 30 days with green/empty distinction
+- Error keys display top 5 sorted by frequency with count badges
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Parent area complete with all required functionality
+- All 85 existing tests continue to pass
+- Ready for remaining phase 03 plans
