mesh/merge-gate pass: builds mesh-host → ace, g14, novox, shanks; no bus step; every machine composes with the change as it did without (4 of 4 compose)
The fourth review (hq issue 339): `trusted` is the catalogue's word and the
controller takes it out, but a controller that passes it on, an older one or
one rolled back to, must not cost a node its whole declaration. A file now
accepts it and nothing reads it; any other resource still refuses it. And a
podman that hangs no longer eats docker's ten seconds.
