- Move pytestmark after all imports in 35 test files (E402: not-at-top) - Add TYPE_CHECKING guard for FlightProcessor in composition.py (F821) - Sort import blocks in src/ and tests/ (I001 auto-fix via ruff --fix) - ruff check src/ tests/ now exits 0 with no errors Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
