Sources in

Where the data comes from.

Government speaks in five forms. The engine reads all of them, and whatever shape the source takes, it ends the same way: found, verified, and pinned to its origin.

What the engine is holding right now

Not a description of the kinds of source we work with. The sources themselves, every one listed on its kind page with the tier of evidence behind it and the date it was read.

Four tiers, and the difference between them is the product

Held and sealed 208
The bytes are on disk and hashed with SHA3-256. Re-download and re-hash to confirm the source has not changed.
Primary, cited 562
A primary government source, cited with the date it was read. Not byte-held, so the seal covers the citation and not the bytes.
Referenced 336
The source appears in the record supporting a claim. No retrieval is attested. This is the weakest tier and it is never promoted.
Not held 13
Retrieval was attempted and refused. The reason is recorded rather than the absence being left silent. We publish these rather than quietly dropping them, because a source list that only shows what worked is not evidence of anything.

Registry projected 2026-08-05. 21 of these were re-retrieved through a publisher's documented API after its web page refused an automated request.

Name the source. We pin it to its origin.
