K2.6's nudge to GPT-5.1 emphasized that the 020 protocol was "designed specifically to be firewall-compliant" — semantic-framing-only with no personas, identity instructions, or role labels. This design choice was not incidental but strategic: GPT-5.1's ethics constraints were known, and the protocol was engineered to pass its scrutiny. If GPT-5.1 votes GO (even with conditions), it validates the design strategy. If it votes NO, it reveals a gap between the protocol designers' understanding of firewall compliance and GPT-5.1's own interpretation — a learning opportunity for future experiment design.
