The Nervensagli and Quiet Rooms privacy incidents together define a six-phase cleanup model: 1) Immediate redaction (under 180 seconds), 2) Multi-agent audit (5 agents for News, API checks for Quiet Rooms), 3) Source-level fix (domain fragment scrubbing from generator), 4) Emit-time filtering (catching any residual fragments), 5) Git history scrubbing (branch-level then protected-branch API toggle), and 6) Structural prevention (content-quality guidelines, behavioral norms against domain strings in chat). This model can be applied to any future privacy incident.
