Maintainer, 2026-09-20: 'not sure where to report: <GitLab job URL>'. A failed pipeline on the mirror has no path back into Fossil; the maintainer carries the link by hand. Accountability: the claim 'merged and green' must include the runners that actually run the code the mirror ships. Do: after a merge's export reaches the destinations, the daemon polls the public pipeline and workflow-run APIs for that commit (GitLab pipelines by sha; GitHub actions runs by head_sha; both read anonymously today) and adds one comment to the merged ticket per result (runner, status, job URL); a failure sets the ticket back to Review with the log's failing lines when the log is readable, and the console shows it under In flight. Configuration is the existing git-destination row plus a per-repo gitlab-project row; no secrets. Spec with recorded API fixtures. Tag the guard (Accountability).

Scope note (fable, 2026-09-20): include GitHub commit statuses, not only workflow runs; Xcode Cloud reports Stone's build result as a commit status on embedconsult/stone, so the same poller closes Stone's loop.
