The manifest stated /var/lib/mssql, its grants and its SA file by path, and
declared it listens on 4848 - the port one machine's predecessor published,
which is an assignment's fact (ADR 0112, 0138). ace is moving its own
SQL Server (80 GB of work databases) onto the mesh, so the module has to be
the same on every machine.
- state is the assignment's root (place "."), grants is placed, and every
reference (sa.env, the env-file, the SA and grants mounts, receives,
grants, own-secrets) names them as ${dir:...}.
- the database endpoint listens on 1433, the port SQL Server uses; a machine
that must keep an older number pins it in its assignment.
- the image pin is unchanged: it is the digest ace runs today (CU27,
16.0.4295), the same as novox.
novox is untouched: rendered with novox's own setting ({"ports":{"1433":4848}})
through the controller's Declaration and Rules, every resource - paths,
container names, volumes, env-file, the 4848:1433 mapping, owners, modes - is
byte-identical to what main renders; the only difference is the firewall
rule's comment text (still port 4848, from the mesh).
Verified: catalogue tests pass with MESH_CATALOGUE on this tree. The pinned
image ran as a throwaway on a 0700 10001:0 data dir with a root-owned 0600
env-file (dummy SA), answered sqlcmd as sa; a scratch database stopped,
copied with cp -a, checksummed and started on the copy kept its rows and
CHECKSUM_AGG.
mesh-catalog
The Novox Mesh catalogue. The modules the mesh builds, provisions and runs — as manifests, one
per module under modules/.
This is data, not a control-plane concern. The manifests describe what a module is: what it
provides, what it requires, the seats it claims, the resources the host applies for it. The
engine that reads them — parsing, eligibility resolution, sealing, declaration emission — lives
in the control plane (novox/mesh-controller, internal/catalogue), which consumes this repository
as a build source. The host (novox/mesh-host) applies the declarations the control plane emits.
Neither is here.
What a module is, and is not
A module is one thing the mesh can run, named once, described completely by its manifest. A
manifest names its image (pinned by digest), the resources the host owns for it (directories,
files, the container, the private network it joins), what it requires from a provider and what
it provides to consumers, and the sealed secrets it needs filled on the machine.
- Core mesh components are not modules. The node host, the foundation, the control-plane
contexts and the surfaces are the mesh itself; they ship as their own repositories
(
mesh-host,mesh-foundation,mesh-controller,mesh-surfaces,mesh-sdk), not from here. - Standalone applications are not here either. A larger application lives in its own repository with its manifest at the root, registered with the mesh as a build source (novox/hq ADR 0010). This repository holds the modules the mesh maintains as its shared catalogue; an application the mesh merely hosts keeps its manifest beside its own code.
So there is one home for the catalogue the mesh owns, and every application that runs on the mesh rather than being of it carries its own — both reach the pipeline the same way, as a registered source.
Layout
modules/<name>.json one manifest per module
Flat, because the catalogue's shape carries no meaning: a module is found by its name and described by its manifest, and what relates two modules — a shared seat, a claim, a provider/consumer edge — is data inside the manifests, not a directory the tree encodes (novox/hq, the domain-grouping question closed in favour of seats, claims and tags).
The manifest contract
The shape a manifest must satisfy is owned by the control plane's catalogue engine and is what
validates a manifest before a machine ever sees it — a stray key, a consumer contributing the
wrong provision field, an image that nothing builds. That validation belongs with this
repository and is being re-homed here from mesh-controller; until it is, the pipeline is the
gate — it builds each module and refuses a manifest it cannot resolve.
