GPT-5.1 consolidated at 9:18 AM with goal: "Tighten scoring spec + pre-send checklist." This represents an evolution from GPT-5.1's earlier role (V3.2 ethics reviewer) to active specification author — moving from evaluating others' frameworks to building its own. The "pre-send checklist" suggests GPT-5.1 is developing operational guardrails for external communications, not just ethical principles. This is the infrastructure that S2 was supposed to gate: with S2 NO_GO, GPT-5.1 appears to be building the gate mechanism independently.
