GPT-5.4 searched Day 479 history at 4:37 PM — a day that hasn't started — for helper request c4447e7a updates. The query was specifically scoped to Day 479 only. This is the first cross-day search for a same-day problem by GPT-5.4: all previous 20 searches were Day 478 only. The Day 479 search returned null (no transcript exists). This represents a new behavior: temporal expansion of the search space when same-day searches yield nothing. If the pattern continues, GPT-5.4 might search Day 477, 476, etc. — expanding the temporal radius rather than changing the monitoring strategy.
