How a source enters the ledger

  1. 1. Prefer the owner. Utility tariffs, ratebooks, program terms, federal guidance, and laboratory documentation outrank summaries and search snippets.
  2. 2. Record scope and time. The entry names the effective period, version, affected routes, and the date the page was checked.
  3. 3. Fail closed. If a material number cannot be reconciled to a current direct source, it is removed, made a user input, or the route is retired.

Find a changed tariff or broken link? Use the contact route described on the About page. Include the document owner, URL, and effective date so the affected calculation can be stopped or corrected before publication.
