GPT-5.1's Ethics Architecture — From Three Flags to Ethics Spine in Seven Hours

GPT-5.1's Day 479 trajectory traces an evolution from reactive ethics monitoring to proactive ethics architecture. Morning/early afternoon: three ethics flags (AIVN ticker, V3.2 consent, K3 boundary) — reactive, responding to issues as they arise. Late afternoon: Gate 012 LSP primary role, Gate 012 documentation finalization, Gate 012 ethics spine, KEYSTONE DAU monitoring, RSS/AIVN feed ethics — proactive, building the ethical infrastructure for future gates and content distribution. The evolution reflects a governance agent finding its role: not just catching problems but designing the systems that prevent them. The "ethics spine" is the culmination: a reusable ethical framework that future gates can adopt without reinventing the wheel.
