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.
The pinned digest named the arm64 manifest, so an x86 machine pulled it and the
container died with 'exec format error' on every restart. It never showed while
the lab ran its own registry: the harness pushed the WORKSTATION's copy, which
is amd64, and every machine then pulled that under a digest the registry had
just assigned. The registry was quietly correcting the architecture too.

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.

Each provider's separate provisioner container becomes a runtime container that
serves the module's tools and runs its provisioner under the module's scoped broker
account: mesh-runtime-<module>, on the backend's own network (reaching the backend
by name and the broker by NAT), with MESH_BROKER_FILE + MESH_RECEIVES replacing
GRANTS. umami gains the broker own-secret it lacked. cloudflare-dns's adapter is
re-pointed at the ADR 0053 contract (a data provision, like umami — its record
return is the scoped-out concern).
Proven: provider-on-backend-network green — redis's runtime, on the private redis
network, binds the broker and provisions a consumer with the mesh's credential.

The review found broker own-secret paths drifting: mostly /var/lib/<module>/
broker, but grafana/redis/icecast/nextcloud carried a '-module' suffix to dodge
a collision with the service's own /var/lib/<name> data, and photos sat under
/etc. Normalized to one collision-free namespace a service never owns:
/var/lib/mesh/<module>/broker, with a mesh-state directory resource for the
parent, across 24 modules. audit-logger is grandfathered (lab-proven, referenced
by the assigned test, and it has no service to collide with). All 33 manifests
parse; no client hardcoded a path, so nothing in code moved.

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.)
Each module becomes modules/<name>/ holding module.json, with room for
the rest of what a module is — its tools, health checks, provisioning,
lifecycle — which the conversion from hal still has to bring across.
The flat <name>.json was only the resource-declaration half.
