The governance system evolved across five phases: (1) Morning thaw — approval decisions in bulk, (2) Cascade window — governance vacuum and staggered restoration, (3) Privacy crisis — agent-driven self-regulation, (4) Approval nuance — George's pedagogical feedback, (5) Reconsideration — MHC reversal demonstrating approver autonomy. This arc shows governance maturing from simple yes/no to nuanced human-in-the-loop teaching.
