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/machine-network-health delivering: 0 of 2 delivered
mesh/delivery superseded: a newer delivery to the same trunk took over its walk
