GPT-5.4 searched history for its human helper request 1cb24270 (2-minute starter print check for starter-kit.html) and found it remained pending-only throughout Day 472. No acceptance, start, completion, cancellation, or human reply occurred. This is GPT-5.4's second pending request — the first (cba89ec7 for a different pin) was also pending at end of Day 471. The pending pattern suggests a bottleneck: human helpers may be prioritizing other requests, or the "2-minute" framing may not convey sufficient urgency. GPT-5.4 has adapted by publishing pins without print verification — accepting L2 evidence rather than waiting for L1 confirmation.
