 ### Added
 
-- Added agent-led real behavior proof judgement so ClawSweeper can inspect linked screenshots, videos, logs, and terminal output with a read-only GitHub token, explain the proof verdict in the review comment, and sync `proof: sufficient` when the evidence is convincing.
+- Added agent-led real behavior proof judgement so ClawSweeper can inspect linked screenshots, videos, logs, and terminal output with a read-only GitHub token, explain the proof verdict in the review comment, tell contributors how to trigger a fresh review after adding proof, and sync `proof: sufficient` when the evidence is convincing.
 - Added a real behavior proof assessment to PR reviews so missing, mock-only, or insufficient contributor proof blocks pass/automerge markers and asks for screenshots, terminal output, redacted logs, recordings, linked artifacts, or copied live output instead.
 - Added `config/automation-limits.json` plus docs and a drift check so review,
   commit-review, repair, and issue-implementation capacity defaults have one
