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, postgres and minio adapters drop generatePassword + the returned credential:
each creates the resource under the login the mesh derived (`as`) with the password
the mesh minted (`p.password`). minio's client gains a secret-key argument so it sets
the mesh's secret rather than generating one. umami (analytics) is re-pointed at the
new contract too; its siteId return is a data-provision concern ADR 0053 scopes out.
Proven: mesh-lab provider-uses-mesh-credential green — redis creates the consumer's
login with the mesh's password, the consumer authenticates (PONG), no seal key set.

Object store, an s3-bucket provider. Client ported with no npm deps: S3 data
plane over fetch + SigV4 (node:crypto), scoped access keys via the mc CLI (the
admin API needs an Argon2 payload node built-ins can't make — the honest port
hal also used). Tools: list buckets/objects, bucket info, presigned url. The
provisioner makes a bucket + scoped key per grant and emits
module.minio.bucket.created/removed (the secret stays off the bus). Typechecks;
manifest parses.
(Trimmed the generated self-consuming ledger: a provider need not subscribe to
its own emits.)
