Development record

Re-running a failed attribution run after fixing the pull-request body (gh run rerun on the old run) replays the event the run was started with, so it checks the old body again and fails. The re-run joins the attribution-<pr> concurrency group and cancels the newer run that the body edit started, which would have passed. On 2026-10-26, PRs #1129 and #1133 each sat red for about four hours: the edited runs 40325771175 and 40325732363 were cancelled, and runs 40298736534 and 40298846131 failed again on the bodies they started with.
