The host member without validate/ failed first against the old judge ("holds no Go files", the validator could not be put in the judge); the controller member is judged by itself whatever the node-engine sibling brings; the group's judge is no longer keyed on the node-engine's validator.
mesh/merge-gate head 37fd73f3781e merged into trunk 4446027108fd — pass: builds build-agent, mesh-controller → ace, g14, novox, shanks; no bus step; every …
A mesh-host change and a mesh-controller change that need each other could not both pass their own checks: each read the other at its base. The check now asks mesh-delivery for the group's open siblings into a base of the same name, reads each at its head merged onto its base, builds the judge from a controller sibling's merge in the isolated judge environment keyed on its inputs, and names the siblings in the verdict. With no answer from mesh-delivery the verdict says it could not learn them; a pull request with no sibling is checked as before. TestReplay867 replays the failure.
