- Add pytestmark = [pytest.mark.<category>] to all 23 root test files and 14 e2e test files - Marker distribution: 22 unit, 7 integration, 1 blackbox, 1 sitl, 5 e2e + 2 e2e integration - Add import pytest to test_models.py, test_download.py, test_synthetic_adapter.py (were missing) - Convert test_sitl_integration.py's bare pytestmark to list form preserving skipif guard - Union of all 5 markers = 298/298 = 100% coverage; 216 tests pass with --strict-markers
