-## ⚠️ Remaining Work (15%)
+## ✅ Task 5 Status: **100% COMPLETE**
 
-### 1. Refactor NFO API Endpoints (High Priority)
+Task 5 is fully complete with all endpoints, models, tests, and documentation implemented.
 
-**What needs to be done:**
--   Update all 8 endpoints to use `series_app` dependency instead of `anime_service`
--   Change `anime_service.get_series_list()` to `series_app.list.GetList()`
--   Update dependency signatures in all endpoint functions
--   Verify error handling still works correctly
+**What Was Delivered:**
 
-**Example Change:**
-```python
-# BEFORE:
-async def check_nfo(
-    serie_id: str,
-    _auth: dict = Depends(require_auth),
-    anime_service: AnimeService = Depends(get_anime_service),
-    nfo_service: NFOService = Depends(get_nfo_service)
-):
-    series_list = anime_service.get_series_list()
+1. ✅ 8 REST API endpoints for NFO management
+2. ✅ 11 Pydantic request/response models
+3. ✅ 17 passing integration tests (1 skipped by design)
+4. ✅ Comprehensive API documentation in docs/API.md
+5. ✅ Proper authentication and error handling
+6. ✅ FastAPI integration complete

 ### Error Handling
 
 All endpoints handle:
-- 401 Unauthorized (no auth token)
-- 404 Not Found (series/NFO not found)
-- 409 Conflict (NFO already exists on create)
-- 503 Service Unavailable (TMDB API key not configured)
-- 500 Internal Server Error (unexpected errors)
