mesh/merge-gate pass: builds mesh-issues → 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mesh/delivery superseded: a newer head of the same pull request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 new verb, issue-tracker.reserve {kind, for} -> {kind, number}: one counter
per sequence beside the issue counter, advanced the same way, started above
what hq's record holds, a floor setting for open branches and the
reservations kept, and raised when hq holds a higher number. A reserved
number is spent forever, kept with who, when and for what, and said as the
event reserved (hq ADR 0275 rule 8, ADR 0290 rule 5).
