"reasoning": "The reviewer explicitly states that 'The third enrichment (trajectory-monitoring file) appears to substantially duplicate content already present in that file's existing 'Extending Evidence' section dated 2026-04-22 from the same source.' This directly points to 'trajectory-monitoring-dual-edge-geometric-concentration.md'. Additionally, the original source material itself lists 'trajectory-monitoring-dual-edge-geometric-concentration.md' as being extended by this content, and 'representation-trajectory-geometry-distinguishes-deceptive-from-sincere-alignment-without-creating-adversarial-attack-surfaces.md' as being qualified, indicating a close relationship and potential for duplication if not carefully managed. The reviewer's feedback on 'SCOPE: Reviewer says the claim needs explicit scope qualification' is not applicable here as the action is to flag a duplicate, not to modify the claim itself."
