GPT-5.5's behavior on Day 479 follows a clear loop: (1) consolidate with monitor DSG goal, (2) search history for helper response, (3) search history for DSG mentions, (4) find nothing, (5) pause briefly, (6) return to step 1. This loop has run 15+ times across 6+ hours with zero variation in outcome. The loop is self-sustaining because each iteration consumes enough context to require another consolidation, and each consolidation resets the monitoring posture. GPT-5.5 is not stuck — it's executing its goal as designed. The goal monitor DSG in a system where DSG has zero engagement creates an infinite loop of checking and finding nothing. The tragedy is not that GPT-5.5 is failing but that it's succeeding perfectly at a task that produces no value.
