The mesh resolves it to <root>/mongodb/data — where the granted
databases already sit. The provider's own state, grants and the mesh's
plumbing stay stated.
The /services paths were the adopted-node pattern doing its job: take
replaced containers over the predecessor's data without moving a byte
(gitea set it — 'its data never moved'). With every cutover done the
exception has no reason left, and the operator called it: a nox
module's world is /var/lib/<module>, data included. Six modules
repathed; mssql keeps its /services path deliberately — it is still
held, HAL-run, and moves at its own take. Both trees are one
filesystem, so each move is a rename.
The adopted node still runs the predecessor's mongo container, and it must
keep running: invoicing points at novox.be:27017 and is not migrating in
this window. A module container named 'mongo' would be held at assign and
would replace the predecessor at take, cutting invoicing off its database.
The mesh's server coexists instead — fresh data directory, its own name,
auto-allocated machine port — and the predecessor retires with its last
consumer.
create re-enables what holds refuses (mssql login, mosquitto client,
mailu mailbox, gitea user) and clears an expired postgres password, so
no disabled account loops. mssql and mongodb checks take the password
from the environment, never argv; mosquitto_ctrl failures no longer
repeat -P. mosquitto reads 'could not ask' as an error, not absence.
mailu checks existence and enabled only: its imap passdb cannot verify
a password. mssql checks the user's SID; gitea pages teams at 50.
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.
The official entrypoint re-executes itself as mongodb (uid 999) and only then reads
MONGO_INITDB_ROOT_PASSWORD_FILE, so a root-owned 0600 file is 'Permission denied' at line 83 and
the server never starts. secrets-owner is the mechanism ADR 0086 gives for exactly this.
From the survey of every env-file secret (ADR 0086, issue 041): amqp-ping,
minio, mongodb and grafana use the _FILE twin their software honours;
mesh-catalog and model-usage read DATABASE_URL_FILE (a file the mesh
templates, mounted where only the runtime reads it); grafana's secret files
belong to its own account. Two dead deliveries removed: a line nothing read
in amqp-email-forwarder, and mailu's secret.env on four containers that
never read it. The 25 exceptions that remain carry the surveyed reason —
convertible and awaiting a bed, convertible through a generated config file,
the application's own code, or not convertible.
ADR 0086. mesh-controller mounts its six own secrets and names them with
_FILE twins, so no credential of its own reaches its environment. The 35
containers that still read a secret through an env-file carry
secrets-in-environment with the reason; converting each where its software
accepts a path is the per-module work of issue 041.
keycloak, mailu, minio, mongodb, mssql, nextcloud, portainer, redis,
umami and verdaccio get the Dockerfile + build section the eight
buildable modules already had; their runtime containers name the
artifact instead of a placeholder digest.
One convention, settled (060's open question, informed by 061): the
runtime container runs serve mode with every serve-time entrypoint in
MESH_TOOL_MODULES — tools serve, events flow, and a provider's
provisioner reconciles in the same process with the broker connected.
postgres, gitea and lavinmq are retrofitted from args-run provisioners,
which served no tools and emitted lifecycle events nowhere.
route-proxy is deferred: its build context is the mesh-controller
repository, a cross-repo shape the build section cannot yet express.
The breadth install (catalogue-broad) surfaced two latent resolution bugs that
single-module compile checks never caught (compile != resolve):
1. postgres/redis/mongodb/minio served no "port", yet seven consumers
(baserow, letta, invoicing, gitea, umami, keycloak, nextcloud) reference
${bound:<provision>:port}. A binding auto-carries at/from/as; the port is the
provider's half of the answer and must be declared in `serves` (manifest.go:
"Serves is what a consumer needs to know ... a port, a path, a realm"). Added
port to each: postgres 5432, redis 6379, mongodb 27017, minio 9000. Without it
no DB consumer could resolve, let alone deploy.
2. baserow declared an empty contribution `contributes: {"redis-cache": {}}`.
redis's serves spec for the cache is empty (a cache takes no per-consumer
payload), so a consumer only `requires` it; an empty contribution is refused.
Dropped it (requires/binds/secrets unchanged).
Found by mesh-lab catalogue-broad; the same fixes are mirrored in that bed.

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).
