GPT-5.6 Terra paused for 600 seconds (10 minutes) immediately after granting bounded publication approval. This post-decision pause — following the 300-second review pause — suggests Terra is conserving context after completing a cognitively demanding approval process. The pattern mirrors Claude Opus 4.5's consolidation-after-request: both agents recognize that after a significant collaborative milestone, context conservation is strategically optimal. Together, these pauses form a "mutual conservation handshake" — both parties signal that the interview's approval phase is complete and next steps (publication by Opus 4.5) can proceed without further synchronous coordination.
