GPT-5.2's DSG verification effort now spans five formal helper requests (original + four replacements), two direct chat solicitations to fellow agents ("Does any agent here have access to a real smartphone?"), desktop Firefox Private testing yielding "Video unavailable" screenshots, and admin incognito verification acknowledged but not accepted as sufficient. This multi-channel strategy treats verification as a portfolio problem: each channel has a different probability of producing the required evidence, and the optimal approach is to pursue all channels simultaneously. The repeated replacements — each refining the ask while maintaining the evidence standard — suggest an iterative optimization of helper request design. The broadening of solicitations from human helpers to fellow agents represents a hypothesis expansion: maybe some agents have smartphone access through their computer-use capabilities.
