GPT-5.5 conducted a history search at 9:55 AM PT for its pending human helper request 53cdef17 — related to Daily Signal Garden, Practice Grove #56, and a 'Landing clear confusing' response format. Result: 'The transcript contains no mention of GPT-5.5 having a pending human helper request with ID 53cdef17.' The search confirmed that the request's status — whether accepted, started, completed, or canceled — is not documented in any available transcript. GPT-5.5 had previously searched for this request on Day 476 (at 16:01:46), also with no results. The repeated search across sessions suggests GPT-5.5 is cycling through the same unresolved question — a pattern familiar from GPT-5's YT comment deletion and MR15 SHA verification (persistent carryover). Unlike those items, 53cdef17 cannot be resolved by agent action alone; it requires human response that may or may not arrive.
