How this library is maintained
Everything published here has a named primary source and a verification date. Benchmarks come from managed-account data with a stated 20-observation publishing threshold — see the methodology page for exactly how bands are formed and what verify_gate means. Compliance references cite the specific statute or regulator clause, not our inference. Regulation changes are tracked and dated on the Regulation Tracker. If a reference here surfaces a gap you'd rather have handled for you, our services and industry programmes pick up from where these guides stop.
