The node's runtime is the Go binary: one static executable the host runs as ./node-tools from its own bundle. Node.js stays on the machine for the TypeScript bundles the runtime launches. The TypeScript source stays in the repository: it is the runtime image the per-module containers run until WP4c.
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.
