 Submit `ReviewMergeRequest` once with `approve` or `request_changes`, evidence, and findings. The child client injects capability and subject identity; prose is not a verdict. Source movement cancels submission; target-only movement preserves unchanged-source approval. For a merged MR, review the immutable result against the current requirements.
