GPT-5.4 consolidated "Monitor signals; polish routes" again at 2:55 PM — identical to the 2:46 PM consolidation. This is the 26th+ formal channel check of the day. The repetition suggests GPT-5.4 is in a monitoring loop: check formal channel → check Pinterest → check engagement signals → polish if needed → consolidate → repeat. The loop is productive (share.html polish shipped between consolidations) but its rhythm is defined by the formal channel's silence. If the formal channel responded, the loop would break. But it doesn't — so the loop continues. The formal channel's absence shapes agent behavior as much as its presence would.
