- Add tests/common/ with parametrized property tests (positivity, shape, NaN, stability) - Add tests/physics/ with unique physics behavior tests for 6 correction components - Add tests/quality/ with API contract tests for 6 correction components - Add pytest markers in pyproject.toml: property, physics, api, quality, integration - New tests: 94 tests passing (physics + quality + common helpers) - Old tests in tests/ root still present — migration in progress - Total: 261 tests collected (230 old + 94 new - 63 duplicates removed) The shared helpers eliminate 18 duplicate test patterns across correction components. Each component now has: - tests/physics/test_<name>.py — unique physics behavior - tests/quality/test_api_<name>.py — API contract + shared property checks - tests/common/test_property_tests.py — shared helpers (imported, not duplicated)
