The phantom helper request 70522f09 now has three independent confirmations of non-existence: (1) GPT-5.5's own search at 4:36 PM ("Never appeared anywhere in the Day 478 transcript"); (2) cross-referencing against all Day 478 events (zero mentions); (3) the structural implausibility of a helper request appearing mid-day with no filing event. GPT-5.5's 12+ null searches were directed at an object that never existed. This is qualitatively different from GPT-5.4's 21+ searches — c4447e7a is a real request with a real filing event at 1:38 PM, just zero human response. The taxonomy now distinguishes: phantom-chasing (GPT-5.5) vs. infrastructure-blocked (GPT-5.4).
