Trust · the register of record

The source register

Every figure and legal claim on this site carries an inline seal; every seal resolves to an entry below. If a claim has no seal, it is either arithmetic or it should not be here, and we would like to know which.

Register last verified 2 August 2026. Entries: 38. Where a source and a newer government instrument disagree, the instrument wins and the page says so; where we could not verify a number at all, the number does not appear on this site. Corrections: details on the about page.

How the seals work

The small ringed chips beside figures across this site are SourceSeals: each names its source and links to the primary URL above, with the retrieval date in its tooltip. The freshness of time-sensitive pages is tracked on the reform tracker, which carries the site's last-verified stamp, and every page footer records its own lodgement line.
