The bed assigned a separate app-postgres, which ADR 0079 now refuses. Converted to adopt the foundation store on anchor and have baserow/letta consume it cross-node over the overlay, with the 057 push-ordering. The store DB path reaches its asserts, but the run is blocked by issue 058: redis's host-networked provisioner cannot reach the broker across nodes (bridge consumers can). Committed as WIP until 058 is fixed. https://claude.ai/code/session_01D6qtiYU3P9jk3pnAXyAFyx

/**
|
|
* Database consumers on a joined node, provisioned from the ONE foundation store over the overlay.
|
|
*
|
|
* The mesh runs a single postgres — the foundation store, adopted in place as the `postgres` module
|
|
* on the control-node (ADR 0078/0079). A module anywhere that requires a database gets one FROM that
|
|
* store, not a second postgres of its own; a second would be refused, because the postgres module
|
|
* claims the mesh-scoped `mesh-store` seat.
|
|
*
|
|
* This bed proves that across two machines. `anchor` is the control-node: it raises the foundation
|
|
* and adopts `postgres` there, so `mesh-store` is the one store and `mesh-postgres` its provisioner.
|
|
* `laptop` joins and runs the CONSUMERS — baserow and letta, which require `postgres-database` — plus
|
|
* a co-located `redis` (which holds no seat). Each consumer's database is minted on the store on
|
|
* anchor and reached over the overlay: their bindings name `anchor.internal`, and their minted logins
|
|
* authenticate against the store. redis stays co-located on laptop for baserow's cache.
|
|
*
|
|
* The four manifests are the committed catalogue shapes (novox/hq ADR 0039/0047/0048), verbatim
|
|
* from the catalogue-broad bed — postgres publishes 5432 so its consumers connect, redis runs on
|
|
* the host network with a lab-local seal key, and baserow/letta wire their servers to the grant the
|
|
* mesh writes. They are added, each issued a scoped broker account, assigned to laptop, and pushed
|
|
* ONCE; laptop converges once with every one up, and the two consumers are provisioned against the
|
|
* database the provider on their own node gave them.
|
|
*
|
|
* It needs a host binary and the foundation bundle:
|
|
*
|
|
* MESH_LAB_HOST_BINARY=.../mesh-host
|
|
* MESH_LAB_BUNDLE=.../examples/foundation-first-node.lock
|
|
*
|
|
* HELPER — stock the four runtimes into the local daemon before the run (some may already be there):
|
|
* scripts/build-module-runtime.sh postgres /tmp/postgres.tar
|
|
* scripts/build-module-runtime.sh redis /tmp/redis.tar
|
|
* scripts/build-module-runtime.sh baserow /tmp/baserow.tar
|
|
* scripts/build-module-runtime.sh letta /tmp/letta.tar
|
|
* The service images (postgres:17-alpine, redis:7-alpine, baserow/baserow:latest, letta/letta:latest)
|
|
* must be in the local daemon too; scenarios/two-node-db.yml stocks all of them, and each node pulls
|
|
* what it runs from the scenario's own registry by digest.
