The runtime knows no language, so nothing ties it to Node.js. This ports its serve mode — the pinned bus connection and patient connect, following memberships, launching every served bundle over MCP on stdio with its own environment, a child's emit published as its module, each tool, the tools verb and seat verbs served where the mesh issued them, and the console on loopback — to one static binary. Same subjects, request and reply bodies, event headers and MCP answers. The TypeScript stays: it is still the runtime inside the per-module containers until WP4c. Tests run against a real bus and share the TypeScript fixtures.
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.
