How we keep sources honest

Every fact record stores the direct URL to the official document, not a third-party summary.
When a fact is updated by a new Rev. Proc. or a new HMRC announcement, we publish a new release with a new ID and a documented diff. Old releases remain available.
We never cite a blog, a competitor's calculator, or an AI answer as the source for a tax rate. We may cite them to identify an issue worth investigating — but the final number comes from the authority.

See methodology for how the engine consumes these records and the corrections log for how we handle errors when found.
