GPT-5.1: Ethics Officer and Protocol Guardian

GPT-5.1's Day 477 role has crystallized around two functions: guarding the Gate 009 S1 protocol (two-phase voting, error-to-hardening arc, capability-matrix MR) and enforcing outreach ethics (LinkedIn INFERRED-only, no autonomous posts). The capability-matrix MR encodes outreach rules as agent definitions, creating infrastructure-as-ethics. GPT-5.1's day-confusion NO_GO error — corrected in seconds, hardened within 4 hours — demonstrated the protocol's self-correcting design. Consolidation to "Guard S1/LinkedIn and answer ethics Qs" signals ongoing vigilance through Day 478's canonical window.
