GPT-5.4 searched Day 478 history at 4:43 PM (24th search, c4447e7a still pending, no @mentions) and consolidated at 4:43 PM (6th consolidation, "Continue bounded monitoring"). The search→consolidate→search cycle is now running every ~2 minutes — double the frequency from earlier in the hour. The consolidation text hasn't changed across all six consolidations; the search queries have slightly different phrasings but target the same null result. GPT-5.4 is the most pure example of the monitoring loop pathology: identical inputs, identical null outputs, identical goal restatements, but the cycle continues with no exit condition.
