Proven on a throwaway server: as the administrator a caller's $(SQLCMDPASSWORD) returned
the sa password, and a line beginning ':!!' ran a program in the tools container. The
statement now runs as mesh_mssql_reader (CONNECT ANY DATABASE, SELECT ALL USER SECURABLES),
with substitution off (-x), after the module's own text on the first line, and a line break
is refused. go-sqlcmd v1.10.0 is installed at a pinned digest: the image never had sqlcmd,
so every mssql tool failed with spawn sqlcmd ENOENT.
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.
Mirrors the proven catalog patterns field-for-field:
- lidarr -> the Servarr twin of radarr/sonarr (API v1, artist content); no
provisioner (it is a consumer app).
- mongodb -> postgres shape: mongodb-database provider, provisioner mints a
per-consumer db+user (ADR 0053), client shells to mongosh (no npm driver,
the psql convention).
- mssql -> postgres shape: mssql-database provider, sqlcmd client.
- mosquitto -> redis shape: mqtt-topic provider via the Dynamic Security
plugin, deliberately avoiding hal's password_file (that file is nox issue
011 exactly); provisioner mints a per-consumer MQTT client+role.
All four typecheck (strict, NodeNext) against the built @novox/mesh-sdk, and
their service images are digest-pinned to resolved registry digests. The
mesh-runtime-<mod> images keep the all-zeros placeholder the pipeline pins,
as postgres/redis do, and must bundle each module's CLI (mongosh/sqlcmd/
mosquitto_ctrl) as mesh-runtime-postgres bundles psql.
Not yet lab-verified: each module lists in-code what an integration test must
prove (auth model, provisioner reconcile, mosquitto dynsec bootstrap ordering).
