The copy quoted above hashes to a5b0fc026ab4b9e0cf4c1b37f474da8b…. If the notice is reworded later, that fingerprint will not match, which is how a reader checks that the quotation was of the version we say it was.
The cross-border matches used on this site are deposited as a citable dataset: doi:10.5281/zenodo.22087136. The recall wording itself is published by the national authority named above and is theirs, not ours.
