Every module named its events the way the old bus spelled a routing key —
`module.<module>.<verb>`. Design 29 says a module names an event locally and the
mesh works out where it lands, so all 37 were stale against a rule already
decided. On the new bus that derives into a namespace belonging to a module
called "module", so no cross-module subscription in the mesh matched anything:
nothing failed, nothing reacted (novox/hq 04-ISSUES/127).
36 manifests converted, and 43 files of module code with them. The code mattered
as much as the manifests: the runtime builds the subject from what `emit()` is
handed, so a converted manifest with unconverted code would have had the
permission and the subject disagree.
Three things the new check found on the way:
- `photos` emitted an event its manifest never declared, which the new bus refuses
outright. Declared.
- `showcase` waited for an event nothing emits, so its demo could never be
triggered — only `showcase` may publish under its own name. It emits both halves
now.
- `distribution` declared an event named after a different module. It emits
`image.pushed` under its own name. An event about a *role* belongs on the seat,
where the name outlives whoever holds it, but the sdk has no way to publish on a
seat yet, so that stays recorded rather than declared.
The audit logger's "everything" pattern is `**` rather than the old bus's `#`.
It claims no seat: mesh-broker is the NATS server's (novox/hq ADR 0119).
The amqp interface stays exactly as it is — a backing service a module may
require, like a database.
The controller now accesses /var/lib/mesh-broker-tls (mesh-controller
#54) and the push refused whole: lavinmq declared the directory as an
owned resource, and shared data is the operator's, owned by no module
(ADR 0051). lavinmq only ever reads the certs — genesis laid them down
— so it declares a read access like the controller does, and the
directory belongs to nobody.
hq ADR 0107 / issue 115. HAL's own postgres and lavinmq both used a
directory bind (./db-data, ./data) for exactly this data -- the mesh's
adoption of them, three weeks ago, switched to a named Docker volume
instead, and searxng/distribution followed the same pattern since.
A named volume survives ordinary container recreation, same as a
directory bind -- that was never the problem. The problem is everything
else: docker rm -fv, docker volume rm, and docker system prune --volumes
all target it (one flag away from the docker rm -f this migration already
uses routinely); it is invisible to every tool this migration has used all
night (ls, find, grep across /var/lib, /services); and nothing outside
Docker's own volume machinery can back it up or notice it growing.
mesh-store carries the sharpest version: every database migrated tonight,
including keycloak's, live inside it.
Data already copied and verified on novox before this merges:
- mesh-registry-data -> /var/lib/mesh-registry (11G, diff -rq clean)
- mesh-broker-data -> /var/lib/mesh-broker (37M, cp -a)
- mesh-broker-tls -> /var/lib/mesh-broker-tls (12K, cp -a)
- mesh-store-data -> /var/lib/mesh-store (1.7G) -- mesh-store stopped
cleanly first, so the final copy is crash-consistent, not a live-file
copy of a running postgres; diff -rq clean after.
- searxng/valkey: not yet assigned anywhere, manifest-only fix, nothing
to copy.
Old named volumes left in place, not deleted, as the rollback path.
mesh-vault provides `secret` (novox/hq ADR 0085, design 24). The value is
the pair credential the controller mints — the vault holds no copy, only a
ledger of who holds one, its fingerprint and every rotation, and two tools that
answer by fingerprint and never by value. Rotation is `rotate secret`,
unchanged machinery pointed at a secret with an owner (design 13). Named in the
mesh's own namespace, beside mesh-controller and mesh-catalog, because it is
the mesh's own code rather than wrapped software.
redis is the first consumer: its own password stops being an own-secret nothing
could rotate and becomes a `secret` it requires, read from the same file into
the same hole. The server now restarts on its config, or it would keep the
password it started with through every rotation (playbook 06).
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 runtime container named no command, so it ran the image default —
the tool host — and the provisioner entrypoint compiled beside it never
ran anywhere: no vhost was ever minted, while the grants sat applied in
its mounted directory. postgres already names its provisioner in args;
lavinmq now does the same. Surfaced by the built-store-cross-node bed,
run 9 — the first bed to reach the vhost assertion honestly.
postgres claims mesh-store, lavinmq claims mesh-broker, and the controller's seat is
renamed the-controller -> mesh-controller so all three follow one convention. The resolver
refuses a second holder mesh-wide, so an adopted foundation module assigned to a second node
is refused rather than silently raising a second server. Closes hq issue 056 (ADR 0079).

mesh-broker serves the amqps bus on 5671 (the control plane and every module's
events) but the lavinmq module declared only 5672, so the firewall's forward
chain — where the broker's published ports are matched — never opened 5671, and
a consumer on another node could not reach the bus over the overlay. Part of
issue 055.

server is now the container the foundation raised — name mesh-broker, the same
pinned upstream lavinmq image, the same TLS args, ports and volumes — so the
applier adopts it in place. The second server, the lavinmq.ini bootstrap and the
module's own network are gone. The provisioner is host-networked to the broker's
loopback management (127.0.0.1:15672) and authenticates as lavinmq's default
guest, which the foundation broker runs with; the mesh bus stays on the / vhost,
a vhost-per-consumer beside it. One lavinmq now.
Issue 051 (WBS 3.2).

The mesh refused to place it — two of its three containers named
mesh-runtime-lavinmq@sha256:000…0, "a placeholder digest, which is never a real
image". That refusal was right, and the belief behind the placeholder was that
lavinmq needs no building because its broker is an upstream image.
The broker is upstream. The module is not the broker. It carries a run-once
bootstrap that writes the broker's configuration before it first starts, a
provisioner that grants each consumer its own vhost and user, a set of tools and
an event consumer — all of it this module's own TypeScript, and none of it
producible by naming somebody else's image.
So it gets what every module with code of its own gets: a Dockerfile standing on
the shared toolchain and runtime bases, a build block naming them, and containers
that name the artifact rather than a digest nothing can produce. Same recipe as
postgres, which is the converted module closest in shape — it has a provisioner
too.
Noted and deliberately not changed: postgres runs its provisioner from its
container's args, and lavinmq's equivalent container names none, so on this
manifest the provisioner is never started. That may be why, or may be a second
fault; it is left alone so the next run says which.

lavinmq becomes a provider of a user-facing amqp interface: a consumer
that requires a message queue is given its OWN broker — a scoped vhost
and user on a lavinmq provider — not an account on the mesh's own
control-plane broker (ADR 0048). Vhost-per-login is the isolation model,
the exact analog of postgres's database-per-login: the provider names a
vhost after the consumer's login and a user with full rights on that
vhost and none elsewhere, so a login is a broker the consumer alone can
reach.
The provider drives lavinmq through its HTTP management API (client.ts,
the module's one impure seam), with a run-once bootstrap that computes
the RabbitMQ-compatible password hash lavinmq's config wants from the
plain admin secret the mesh mints — the value no ${secret:...}
placeholder can produce and the reason the bootstrap exists (ADR 0052).
serves.amqp carries the port so consumers reference ${bound:amqp:port}.
amqp-ping is a demo consumer: it contributes nothing (the vhost is the
login), reads its grant from an env-file the mesh fills, and uses
${bound:amqp:as} for BOTH its username and its vhost — the db-name
lesson applied to AMQP. It speaks AMQP 0-9-1 over a raw socket with no
npm dependency (the way redis speaks RESP) and round-trips one message.
It carries a slug so its identity fits the 20-char backend bound
(ADR 0049).
