Every served entrypoint is started as a process speaking MCP over stdio, told its module and node; one that is not executable is refused by name. The import path, the SDK resolve hook (issue 209) and the per-registration hand-off go. The one-module form the per-module containers use is still imported until they move (to-be 38 WP4c). A child's mesh/publish is published as its module and answered once accepted; a child that dies says why in its own last words. Fixtures are served through launchers exactly as the builder writes them.
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.
