mesh/merge-gate pass: builds mesh-delivery → novox; no bus step; every machine composes with the change as it did without (4 of 4 compose)
mesh/repo-check pass: its merge-check.sh passed, each part in its toolchain: merge-check.sh (go), merge-check-typescript.sh (typescript)
mesh/delivery superseded: a newer head of the same pull request
A superseded member counts as reached when a later delivered walk on its trunk carried every module it moves (ADR 0270's covered test); otherwise the group reads stopped, as groupTurns already treats it. Five groups read "delivering, 1 of 2 delivered" for days with nothing in progress (novox/hq issue 442).
