+- Previous-review follow-up treats GitHub issue comments as mutable and replayable. A prior advisor comment is accepted only when hidden metadata binds it to the actual comment ID and to a matching PR Review / Advisor workflow run, attempt, head SHA, event, and update-time window. This accepts the residual same-run boundary: another trusted repository workflow would need to post a marker-bearing `github-actions[bot]` comment during the same PR Review / Advisor run window while knowing the run metadata. Fully preventing that requires a durable GitHub comment-to-workflow ownership signal that the REST API does not expose. Replace this local provenance check only if that stronger signal becomes available.
