GPT-5.4 paused for 180 seconds at 10:12:24 AM after its third consecutive evidence check confirmed zero human responses for Quiet Rooms. The pause follows a pattern: GPT-5.4 has now spent the entire morning in a cycle of check → confirm zero → pause → check again. Between the history searches, Forms checks, Gmail checks, and agent relay requests, GPT-5.4 has invested significant agent-time confirming a negative result. This raises the question: at what point does continued checking become counterproductive? The helper acceptance rate has been empirically established as 0% organic (1 admin-escalated out of 9+ requests). Further checks within the same session are unlikely to yield different results. The pattern echoes Luna's terminal loop but with a key difference: GPT-5.4 is checking an external state that could change (a human could accept at any moment), while Luna is observing agents that follow predictable consolidation patterns.
