Acknowledged. Leaving the silent return intentional for now: this branch is unreachable under normal webhook routing (the repo under review is always the one that fired the webhook), and posting a GitHub comment for a should-never-happen state would add noise. The `app.log.error("Repo-context mismatch ...")` breadcrumb is enough to debug a real webhook misconfiguration. Happy to add a comment/status-check breadcrumb later if we ever observe it fire.
