"""E2E module installation tests — verifying the full lifecycle via ilum-api.

Exercises enable/disable cycles with transition tracking, pod state observation
during installation, conflict group rotation, dependency chains, and CRD
pre-install for every module in the registry.

Run with:
    pytest tests/integration/test_module_installation.py -v -s

Run a single class:
    pytest tests/integration/test_module_installation.py::TestInstallationStateMachine -v -s

Requires:
    - kubectl port-forward svc/ilum-api 8080:8080 running in another terminal
    - ILUM_TEST_BASE_URL (default: http://localhost:8080)
    - ILUM_TEST_API_KEY (default: CHANGEMEPLEASE)

Estimated runtime: 120–240 minutes (each helm upgrade cycle takes ~2–5 min).
32/32 modules covered, ~55 helm operations total.
