+(pass/fail.) The base fails are the predicted ones: "startup token refusal returns safe code...",
+"proof startup refuses partial flags...", "11: the CLI refuses --sso...", and in stack-instances the
+0644 subtest "alpha and beta get a 0700 config dir..." plus its parent T-I1 (so 2). stack-instances has
+one more test on the candidate (the umask 077 subtest). No unpredicted failure.
