WIP: catalogue-apps install bed (mongodb, unifi, marrytts)
Adds the mongodb runtime CLI (mongosh) to build-module-runtime.sh, a catalogue-apps scenario, and its install test. Proven so far: the ADR-0054 slug applies and the mesh accepts the push (mongodb consumer identity mesh_anchor_mongo fits). NOT green: the node applies but never reaches 'current' within 1200s — a persistent reconcile divergence (applied-but-never-current, no crash), likely a module declaring a resource its container mutates (issue-011 class). Needs live VM inspection to name the module. Not merged. Claude-Session: https://claude.ai/code/session_01LrgweAeERJYBg88c5cKDzF

/**
|
||||
* The mesh assigns a SECOND wave of modules to one node in a single push — the ones converted this
|
||||
* session — and they resolve and come up together. catalogue-small's sibling, a heavier group.
|
||||
*
|
||||
* The four exercise the three converted shapes (novox/hq ADR 0039/0048/0052):
|
||||
* - mongodb — a database PROVIDER shaped like postgres: a server and a broker-bound runtime
|
||||
* (carrying `mongosh`) on the private mongodb network, the runtime running the provisioner over
|
||||
* the ADR-0048 MESH_RECEIVES contract. Its consumer proves the provisioner ran by connecting
|
||||
* with the mesh-minted credential.
|
||||
* - unifi — a tooled APP shaped like plex: a server and a broker-bound runtime that serves the
|
||||
* module's tools under a scoped account. No provisioner. (Lab credentials are set on the runtime
|
||||
* so unifi's client constructs and its tools register — as plex is given a lab token.)
|
||||
* - marrytts — a manifest-only PLAIN container: no runtime, no tools, no broker account. The proof
|
||||
* is simply that its container comes up under the co-resident push.
|
||||
* - postgres — the known-good provider control, verbatim from catalogue-small, so a mongodb-only
|
||||
* provisioning failure is unmistakable against a provider that is already proven.
|
||||
*
|
||||
* All are assigned to the one anchor, pushed ONCE, and the node converges ONCE with every one up.
|
||||
*
|
||||
* MESH_LAB_HOST_BINARY=.../mesh-host MESH_LAB_BUNDLE=.../examples/substrate-first-node.lock
|
||||
* scripts/build-module-runtime.sh {mongodb,unifi,postgres} build the runtime images into the local
|
||||
* daemon; scenarios/catalogue-apps.yml stocks them. mongo:7, lscr.io/linuxserver/unifi-controller
|
||||
* and synesthesiam/marytts must be in the local daemon to be stocked.
