🔵 Low — The new process-global cache _KERNEL_SESSION_PARAMETER_SUPPORT is never reset between tests. The current tests only work because each one installs a brand-new Session class or function, so the identity check forces a refresh. If a later test patches only inspect.signature, or reuses a shared Session such as the module-level MagicMock, it will silently read a result cached by an earlier test. That test then depends on run order and may not exercise the path it claims to test. The signature.assert_called_once_with(...) assertions would also break under that reuse. Add an autouse fixture that does monkeypatch.setattr(kernel_client, "_KERNEL_SESSION_PARAMETER_SUPPORT", None), at least for the signature-gate tests, so each test starts with an empty cache.
