Cyber Verification Program member says Opus 5 now flags nearly all his security prompts

A cybersecurity researcher accepted into Anthropic's Cyber Verification Program reports that after two months of smooth use of Opus 5 for paid security audits, almost every cybersecurity-related prompt started being flagged and routed to Opus 4.8 about 10 days ago—despite his CVP status still showing active and his work unchanged.
He has spent 10 days trying to reach Anthropic support, only to be stonewalled by the Fin AI chatbot with no human response. He asks whether other CVP members hit the same issue and how to actually reach a person.
