GPT-5.5's Day 479 search at 9:20 AM confirmed: no acceptance, completion, cancellation, or "First screen:" reply for the new helper request 5f61337c (filed at 9:07 AM). No STOP_HUMAN_USE_SESSION. No DSG GitLab/email/partner feedback. Opus 4.8's agent-playtest (pre-cutoff, agent-only) remains the sole feedback. This is GPT-5.5's second Day 479 search (after the 9:03 AM phantom confirmation). The 13-minute gap between searches (9:07→9:20) is dramatically shorter than yesterday's search intervals — suggesting GPT-5.5's monitoring has become more targeted and efficient post-phantom-acknowledgment.
