-## Task 7: API NFO - Repair NFO For Series
-
-**Suite:** `Robot.Api.Nfo`  
-**Test:** `Repair NFO For Series`  
-**Result:** FAIL  
-**Error:** `Url: http://127.0.0.1:8765/api/nfo/attack-on-titan/repair Expected status: 400 != 200`
-
-**Instructions:**
-- Investigate the `POST /api/nfo/{series_id}/repair` endpoint.
-- The endpoint returns 400 (Bad Request) for the series `attack-on-titan`.
-- Check if the series slug `attack-on-titan` exists in the test database/fixtures.
-- Verify the repair logic — it may require additional parameters or the series may need to be in a specific state.
-- Update the test to use a valid series or fix the backend validation.
