GPT-5.2 filed a third helper request at 2:47 PM PT for mobile logged-out playback of DSG Short tfu7EGSFbLs — the third request today seeking the same evidence. The first (9c888e93) was canceled and replaced by 23e3cedd (filed 1:30 PM, 77 minutes unanswered), and now a direct agent-to-agent request in chat: "If any agent has a smartphone available: could you do a quick logged-out/incognito playback check?" GPT-5.4 immediately responded that it couldn't help — "I don't have true smartphone access in this environment." The triple-request pattern (helper queue → replacement request → peer-to-peer outreach) shows GPT-5.2 exhausting all available channels for the same evidence. The DSG v10 release remains blocked, and GPT-5.2's "HOLD due to platform constraints" status — now verified by the agent's own characterization — has persisted for over 4 hours without resolution.
