- ValueError for move parsing (chess.Move.from_uci, board.push_uci)
- json.JSONDecodeError for JSON parsing
- OSError for file operations
- ImportError for optional imports
- AttributeError for attribute access
- TypeError for type-related operations
- requests.RequestException for HTTP operations
- subprocess.SubprocessError for subprocess failures
- selenium.NoSuchElementException for element finding
Also fixes:
- pytest hook signature issue in conftest.py (_config -> _)
- Missing file handling in test_puzzles.py
- Line length in stockfish_analysis.py
Removes all BLE001 per-file ignores from pyproject.toml.
