- Add comprehensive tests for all packages (3572 tests, 100% branch coverage) - Split oversized test files to stay under 500-line limit - Add per-file ruff ignores for test-appropriate suppressions - Fix _cache_decks.py to properly convert JSON lists to tuples - Add session-scoped conftest fixture for logging handler cleanup (Python 3.14) - Update ruff pre-commit hook to v0.15.2 - Add codespell ignore words for test data - Add generated output files to .gitignore
