mesh/merge-gate pass: builds build-agent, mesh-controller, route-proxy → ace, g14, novox, shanks; no bus step; every machine composes with the change as it…
mesh/repo-check pass: its merge-check.sh passed
mesh/delivery stopped: covered: its merge e7dca6c280bd is contained in cec797e996b2 which is delivered (walk plan-1791499975016484055); closed on the ope…
Build and register a new module when its merge lands (hq issue 300)
The delivery plan said a merge adding a module builds it, sent nowhere;
the merge built nothing, so the module was never registered and assign
refused it. The merge now asks for the build of every directory it adds,
outside the plan, and the take-in registers it like a hand build.

// the merge said it changed nothing any module the mesh holds is built from, and built nothing, so the
// module was never registered and `assign` refused it. The merge asks for its build, at the branch merged
// into, from the repository as the mesh spells it — and opens no plan, since nothing it holds moved.
