The fact-check found mailu, whose user is its mailbox, so 0114 rotates
over two credentials rather than two logins, the adapter choosing what a
credential is. Also: minio keeps non-empty buckets; five backends take
their admin credential only at first init, so single-party rotation is
staged; postgres ownership moves to a non-login role; the harness keys by
consumer; rotation state lives with the vault. Consistency fixes across
0110-0113, 26 and 27; issue 103 resolved by mesh-host PR #22.
