"""Unit tests for Phase-2 discovery additions (plan §4.1).
Proves the `custom_tests` discovery covers exactly the per-recipe `custom/` dir, still honors the
deprecated `functional/` + `playwright/` aliases, excludes top-level lifecycle `test_<op>.py`
names, and honors the HC2 repo-local approval gate.
Run with: `cc-ci-run -m pytest tests/unit`. Located under tests/unit/ so the orchestrator never
picks these up as overlays/custom tests.
