What changed and when
We re-verify on a quarterly cycle and whenever an authority changes its charges or code list. Every revision is logged here, dated.

Initial build
First publication: London Councils / TfL common-framework contravention codes, statutory grounds for appeal under the civil-enforcement regulations, the procedural deadline ladder, the appeal-body routing (Traffic Penalty Tribunal, London Tribunals, POPLA, IAS), and the client-side letter builder. Every figure cited to a primary source with a last-verified date.
