- AssertCheckpointsOnRemote (git-refs arm): surface git errors instead of
reporting a misleading "found none" via gitOutputSafe
- RemoteCheckpointState: fail the test on git error instead of returning
"" (two broken invocations comparing equal would pass vacuously)
- hermeticity self-test comment: the guard is per-host http proxy entries,
not an insteadOf redirect
