+# Phase 1 Plan 1: Foundation Summary
+
+**WordPress plugin infrastructure with CPT registration, admin menu structure, and proper activation hooks**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-01-16T02:01:12Z
+- **Completed:** 2026-01-16T02:02:52Z
+- **Tasks:** 3/3
+- **Files modified:** 3
+
+## Accomplishments
+
+- Main plugin file created with proper WordPress header and activation hooks
+- Custom Post Type `umzugsliste_entry` registered for storing form submissions
+- Admin menu structure created with Einträge and Einstellungen submenus
+- Plugin follows WordPress Coding Standards with German localization
+
+## Task Commits

+1. **Task 1: Create main plugin file with bootstrap code** - `bdf02a2` (feat)
+2. **Task 2: Register Custom Post Type for form submissions** - `59acfae` (feat)
+3. **Task 3: Create admin menu structure** - `253129c` (feat)
