Try the decision engine
Send an action, see the verdict, approve or reject it, then edit a record and watch the chain check catch it.
This is a sandbox. It runs the same policy evaluator and redaction code as the production API. Evidence records are hashed field by field with SHA-256 (hash version 2), against a fixed set of five policies. Nothing is stored and no account is needed. The default for unmatched actions is BLOCK.
