mesh/delivery delivered
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-group group feat/a-machine-joins-through-the-tunnel delivered: every member is delivered
The rows of novox/hq ADR 0169's table the controller answers for: the hub's composed tunnel carries a machine whose live token was issued for its key, drops it when the token expires unused, and nothing is recorded for something that is not a tunnel key.
