From your own quote: > they merely enable you to audit whether it has been tampered with That's literally the entire point here (if I've understood correctly). If anyone tried to falsify even the slightest detail, including Honeywell or an entity hosting the database on their behalf, you can be reasonably certain that you would notice it. The history of each serial number becomes effectively immutable once entered into such a database, which is presumably a very good thing given what these parts are used for. I'd love if purchasing a used car came with anywhere near that level of guarantee about its history.
