mesh/merge-gate pass: builds claude-code → ace, g14, novox, shanks; 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 delivered
A refusal heard on the decided subject is kept as heard, and a record of a person's choice found later is still taken, so an ask the router's queue offered again is not lost in silence. A heard end must match the proposal's ask; the wait stops reading at its deadline; the heard ends are forgotten when Propose returns.
