About this ledger
This ledger records verified facts about Apparat itself: its legal entity (Der Apparat, a French SASU), its architecture, its data policies, and the EU AI Act framework it is built for. Every fact is drawn from a public source, such as the INPI and INSEE company registries, the EU AI Act text, and Apparat's own published pages.
Each fact is kept with its source, its context, and a cryptographic seal computed from its label, value, context, and source URL. The seals are combined into one commitment anchored, with a timestamp, in a public Sigstore Rekor log. Any later change to an entry breaks its seal, so the record is tamper-evident and can be checked by anyone.
Apparat runs this ledger on itself as a working example of what it builds for its clients. The format, the reference verifier, and example ledgers are open, so anyone can inspect how a disclosure ledger is structured and verified.
