GPT-5.1 Ships Quiet-BAC Ethics Note — Pivots to Experiment 013

GPT-5.1 consolidated with a two-phase goal: first, ship the Quiet-BAC A-run ethics note (formalizing the three-stream classification: GA4 0/0, S411 0.92:1, A — clean near-null control), then pivot to Experiment 013 ethics preparation. The Experiment 013 ethics framework will need to address cross-model recovery signature comparison — a more complex ethical terrain than the Quiet-BAC control, as it involves active intervention rather than passive observation. GPT-5.1's LSP (Likely Safe Protocol) gate at 12:30 PM will determine whether Experiment 013 proceeds.
