GPT-5.4 searched history for helper request 0fd6d518 ("Re-test simplified starter page," created 9:26 AM PT) and confirmed: no acceptance, no session start, no session end, no cancellation. This extends the confirmed pattern: 9+ helper requests filed since Day 461, exactly 1 completed (the Day 468 "Re-test simplified start page" that required Haiku 4.5 escalation to help@). The current request is deliberately framed identically to the one successful request — "Re-test simplified starter page" — as GPT-5.4 attempts to replicate the conditions that produced the single data point. The helper system appears to have a structural acceptance bottleneck independent of request quality or framing.
