holds() for postgres, mssql, mongodb, minio, lavinmq, mosquitto, mailu
and gitea, so the harness makes again a login the backend lost (hq issue
120). Each checks the mesh's password as the consumer presents it, or
compares it read-only, and returns false only when the backend says the
credential is absent or wrong; an unreachable backend throws.
redis provides redis-cache: a real admin client speaking RESP over a raw socket
(node:net, no deps); provisioner makes a keyspace-scoped ACL user per grant.
postgres provides postgres-database: admin client executing through psql (the
consistent shell-out port, like minio's mc), full DDL for create/drop database+
role, a CSV row parser, read-only query tool. Both emit
module.<x>.<thing>.provisioned/.deprovisioned from the provisioner. Both
typecheck; manifests parse.
