mesh/merge-gate pass: builds gitea → 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 delivered
An agent could not get a finished change onto the forge without someone pushing by hand, so the branch / pull request / approval rule could not be followed. A Go bundle serves gitea_commit, held to gitea_api's rule (never the default branch, never a protected one), and the summarised reads agents otherwise made through gitea_api as raw JSON.
