Explainable output accounts for why an authorization request received a particular outcome. It connects the decision to the governing policy and relevant identity or entity relationship, helping policy owners verify intended behavior. section 17.2.1
Explaining a document decision
For “Why is Kate allowed to view the Q3 plan document?”, an explanation can identify a specific permit policy and state that Kate belongs to the document’s reader relationship. The explanation remains a verification aid, not an authority: engineers check it against the actual policy evaluation trace. section 17.2.1
Useful explanations expose decisions clearly enough to reveal policies that are technically correct but poorly expressed. At organizational scale, explainability supports observable, consistent authorization and helps answer not only what happened, but why. section 17.2.1 section 19.4
