Statically analyze a pytest conftest.py chain: render the fixture dependency graph across all five scopes (function/class/module/package/session), detect deeper-conftest overrides, ScopeMismatch edges, and cross-test state pollution — mock.patch().start() without .stop(), monkeypatch leaking from broad-scope fixtures, and with mock.patch held open across yield.

Test Python re patterns online: (?P<name>…) named groups, (?P=name) backreferences, VERBOSE patterns, findall behavior, and \g<name> replace templates — plus ready-to-paste Python code.
