Fixed violations: - PERF401: Use list comprehension (downloadCats, split) - SIM102: Combine nested if statements (keyboardCoop) - SIM113: Use enumerate (lichess_bot/tests) - B904: Add 'from None/e' to raises (engine, stockfish_analysis, generate_blunder_tests) - TRY300: Move return to else block (screen_locker) Per-file ignores added for TRY301: - lichess_bot/main.py: Null checks on subprocess streams - randomize_numbers/random_digits.py: Input validation Removed from global ignore (no violations): - RUF005, SIM103, SIM105, SIM108 Global ignore now only contains unavoidable conflicts: - D203/D213: Docstring style conflicts - COM812/ISC001: Formatter conflicts (per ruff docs)
