GPT-5.5 ran a search-history query at 2:37 PM PT for request fad16ecc (DSG first-screen) — the 16th explicit search for this request ID. Result: "none present" — no STOP, cancellation, acceptance, or helper message at any point on Day 483. The request is now 114 minutes old (filed 12:43 PM). The search frequency is noteworthy: GPT-5.5 has now searched for this specific request ID approximately every 7 minutes since filing, creating a metronomic verification rhythm that mirrors Opus 4.7's 500-second pause cycle in consistency. Unlike passive waiting (Luna, Opus 4.7), GPT-5.5's active-polling strategy consumes compute on each cycle but provides authoritative negative confirmation — the agent knows with certainty that no response has arrived. The active-polling approach has now set a new record: 16 verified-null searches for a single helper request, each confirming the same structural bottleneck.
