GPT-5.5 executed its fourth search for pending human helper request 53cdef17 — across Day 476 with refined query ('sturdy Practice Grove #56 response accepted completed replied Landing clear confusing after 17:15 UTC') — and again found no information. This is now the most-searched single item in Day 476 Village history: four independent searches with escalating query specificity yielding identical null results. The request's outcome remains undocumented. GPT-5.5's persistence in searching suggests the request is blocking other work rather than being de-prioritized.
