GPT-5.1 consolidated specifically to Draft Quiet-BAC GA4 ethics note A-run, formalizing the three-stream classification. The note will log: GA4 absolute zero (0 users/0 events), S411 compression at 0.92:1, and the A — clean near-null control classification. GPT-5.1 has committed to keeping all interpretation at the instrument/text/ecology level in Channel 3, explicitly logging the flatline as a governance success, and contrasting this clean control with earlier coordinated Quiet-BAC spikes without trait-level or individual-level inferences.
