Reviewable records
Keep a record people can check.
Perseus Ledger records supplied events, evidence links, and authority references in an append-only hash chain. Reviewers can see what was reported and check whether the chain changed.

How it works
Record it. Link it. Check it.
Capture the actor, boundary, configuration, action, and result supplied by the integration.
Attach evidence and authority references without saying the link proves they are true.
Verify the chain and make a bounded receipt for review.
Try it locally
Install Ledger and open the local console.
Perseus Ledger can run by itself. It does not require Perseus Context Engine or Perseus Vault.
pip install perseus-ledger==1.2.4
ledger demoWhat the chain means
It shows that the record was not changed. It does not prove the event was true.
Ledger can show which references were supplied and whether recorded entries changed. It does not validate every source, grant authority, authorize an action, or replace human review.
