Existing failing test is tests/gateway/test_status.py::TestGatewayPidState::test_get_running_pid_rejects_live_non_gateway_pid and must not be edited. Reproduce it RED first. Root cause: _read_pid_record returns None for untrusted legacy numeric/malformed authority files, but get_running_pid currently calls _cleanup_invalid_pid_path whenever lock inactive and identity not unknown, deleting the unsafe path. Preserve any existing unvalidated/untrusted primary PID path fail-closed; still clean a validated JSON authority record that is stale/mismatched, and still clean stale lock metadata when no unsafe primary path blocks touching authority. Inspect nearby symlink/mode/legacy/stale tests to avoid weakening them. Use apply_patch only. Then run the focused failing test GREEN, all tests/gateway/test_status.py once cache-disabled, Ruff on changed file, strict type diagnostics/tooling used by the repo, and a minimal manual driver exercising both legacy-preserved and valid-stale-cleaned branches.
