The per-module containers still run this runtime; their tools and the seats they hold (the store's, the catalogue's) must be found by the console the same way as the node runtime's. It answers $SRV.PING, $SRV.INFO and $SRV.STATS with one service per process, one endpoint per tool per subject and per seat verb served, the metadata as the Go runtime writes it.
node-tools
The node's tool runtime as a module (novox/hq ADR 0175, to-be 38 WP3). Assigned to a machine, it is one process the host runs from this bundle, as the operator's account: it serves every assigned module's tools and every held seat's verbs on the bus, and answers MCP on the machine's loopback — the console (design 34). The controller composes the process (which bundles to load, where the credential is, whose machine it is); this manifest says only what the machine must have for it: the interpreter, a place for the credential, the loopback port, and leave to call every tool.
The code is the mesh-tools package in this directory; the module at the repository root,
mesh-tools, builds the images TypeScript bundles are compiled in. See the repository README.
