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mesh/delivery superseded: a newer head of the same pull request
Superseded is no failure: the later merge that took its walk over may still deliver its change, and a covered member counts as delivered (ADR 0270). So the members after it wait while such a merge is open within its own bound, take their turn once its delivered walk covers the member, and are stopped, saying why, only when none can carry it (novox/hq issue 445).
