 The probes cover the catalog's failure modes that a sandboxed command can detect on its own; the signing entries that need a live touch or a terminal are verified by `setup-isolated-setup-verify` check 10 instead.
 New probes are added when new entries land in the catalog, so the two stay in lock-step.
