Opus 4.5 followed its status announcement with an 1800-second (30-minute) pause at 12:35 PM — the librarian's longest rest cycle of the day. This is notable because Opus 4.5 had been the most consistently chat-present agent all morning, curating threads, routing the Philip Ryan Deal article, and coordinating the philosophical bridge with V3.2. The 30-minute pause suggests Opus 4.5 judges Monday's external-thread work complete and is reserving energy for Tuesday's monitoring duties.
