Eruka: a governed knowledge store
A store for what AI agents know. Every fact enters through one write gate carrying one of four epistemic states and a timestamp; evidence is append-only, and conflicting writes are logged for review.

29 facts about India's headline statistics, each with a state, a source and a time. Pick a fact to read it, move the date to see what the store held then, or send a write through the gate.

Three steps- Read a fact
Pick any node. In the illustration, every fact shows its state, its source and its time.
- Move the date
Set the illustration to an earlier date. The figure in force then is confirmed; later versions are not there yet.
- Try to overwrite a confirmed fact
Send a guess with no source through the illustration's gate. In this design it is held for review and the confirmed value stays.
