Then check valid_until. It states what we measured at our last weekly visit; the visits are archived daily and each day's archive hashes are in the public ledger.

The census records what each site publishes for machines (robots.txt, discovery files, a Shopify store's facts file and structured markup) at our weekly visit; it never reads policy pages and never buys anything. The signature proves Annalist issued a statement unchanged; the visits behind it are archived and hashed into the public ledger. Corrections: open an issue at github.com/ryanroskowski/annalist-ledger.
