mesh_overview, mesh_machine, mesh_search, mesh_describe and mesh_call walk the mesh's structure; every tool has one address per layer: <seat>.<verb>, <node>/<seat>.<verb>, <node>/<module>.<tool>, and <module>.<tool> for a module the mesh issued a plain subject. A stateful module called without its machine, a node seat without one, a mesh seat with one, or a module on the wrong machine is refused naming what would work. Answers come from the mesh when asked, kept five seconds, so a tool that arrives mid-session is found. The flat catalogue stays behind MESH_CONSOLE_FLAT=1 and old <module>.<tool> names still answer.
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.
