What was found

A CSV on the state open data portal under CC-BY, described as active licensees at the date of publication. The gap is history: the commission declines to publish earlier versions, on the stated grounds that doing so risks publishing data that is no longer correct, and points anyone who wants them at a Right to Information application. So you can check a licence now and you cannot establish what the register said on the day the money moved, which is the only question that matters after a fraud.

What it publishes

CheckAnswerWhy it matters
A public page per licenceYesGives a reader something to look at and a checker something to archive and attest against.
A bulk exportYesLets a consumer hold the whole list instead of fetching one licence at a time, and lets anyone hash it.
Machine readableYesA CSV or JSON rather than a page built for a browser. Decides whether checking can be automated at all.
SignedNoMakes the file impossible to forge or mirror convincingly. Nothing reaches grade A without it.

The next step

Sign the file

The export exists and is machine readable, which is the expensive part. What remains is a key and one DNS record on a domain the authority already controls, which makes the file impossible to forge and takes this row to grade A.

A grade describes a register, not the authority behind it and not the quality of its supervision. An authority can run an excellent register and still sit at grade D because it is a search form.

If this row is wrong, it gets corrected with the correction published beside it. The index is useful only if it can be argued with. Tell the lab.
