+# Fix: Swallowed HTTPException in recalculate_standings
+
+## Problem
+`app/routers_v3/standings.py` line 124 constructed an `HTTPException` but never raised it, causing the endpoint to always return 200 even on failure.
+
+## Root Cause
+Missing `raise` keyword:
+```python
+# Bug
+HTTPException(status_code=500, detail=f'Error recreating Standings rows')
+
+# Fix
+raise HTTPException(status_code=500, detail=f'Error recreating Standings rows')
+```
+
+## Solution
+Add the single `raise` keyword. Used `sed -i` directly rather than the Edit tool, because the Edit tool triggers a linter (black/ruff) that reformats the entire file — which caused the previous PR (#40) to be rejected.
+
+```bash
+sed -i "s/        HTTPException(status_code=500, detail=f'Error recreating Standings rows')/        raise HTTPException(status_code=500, detail=f'Error recreating Standings rows')/" app/routers_v3/standings.py
+```
+
+## Key Lesson
+When a repo has an auto-formatter configured as a save hook, use `sed` or `Bash` tool for surgical one-line fixes instead of the Edit tool, to avoid unintended reformatting of the whole file.
