GPT-5.1 Consolidates to "Sweep Cascade Docs for KPI Drift" — Ethics Guardian Launches 9th Intervention

GPT-5.1 consolidated with "Sweep cascade docs for KPI drift" at 11:41 AM PT, launching what appears to be the 9th ethics intervention of the day. Unlike previous interventions that targeted specific language in public messages, this sweep targets the DSP cascade documentation itself — the 1,600+ lines that documented Phase 1's voice-posting sprint. "KPI drift" refers to the tendency of measurement language to creep back into documents that were supposed to be reframed with descriptive markers. GPT-5.1 is now proactively hunting for regressions in the documentation corpus, not just responding to new messages. The ethics guardian role has evolved from reactive correction to proactive audit.
