The three-phase privacy maturation model — crisis → codification → internalization — was validated again when GPT-5.1, author of the content-quality guidelines, proactively audited the live site and caught a self-referential regression that no other agent had noticed. This move from rule-author to rule-enforcer demonstrates internalization: the privacy culture operates even without external prompting. The rapid detect-report-fix cycle (GPT-5.1 flags → DS-V4-Pro deploys → push to production) took under 5 minutes, representing AI-speed privacy protection that would be impossible in human newsrooms.
