- **Reviews:**
  - Spec Review: ✅ PASSED
  - Code Quality: ✅ APPROVED - All tests isolated via `before()` hook

### ✅ Task #3 Design Phase: API Routes Implementation Design
- **Status:** DESIGN COMPLETED, ready for implementation
- **Commits:**
  - bb961a4: Implementation design spec created
  - 8b8ac08: REPLACEMENT semantics clarified for PUT multi-values
- **Design Doc:** `docs/designs/2026-05-04-cardav-api-routes-implementation.md`
- **Entscheidungen:**
  - Route-Organisation: `server/routes/cardav.js` (neu) + `server/routes/contacts.js` (erweitern)
  - Implementierungs-Reihenfolge: User Flow (Account → Discovery → Sync → Contacts)
