itself — no engine, no database, no tenant state. POST an approved decision’s verifiable_bundle VERBATIM to confirm that verdict without trusting the decision endpoint (the same check ships as the open, dependency-light nsr-proof-core crate for fully offline verification). Always returns 200 with a verdict: an unsound proof is a valid answer (verified:false + the located reason), not a client error. The body is the raw knowledge::ProofBundle — {facts, rules, proof, org_id?, as_of?} — exactly as verifiable_bundle emits it; hand-authored bundles are documented in docs/GETTING_STARTED_SCENARIOS.md.

Required scope: write

Request body

JSON body of type object.

Response

ProofVerifyResponse

failed_step · integer

The step index the failure anchors to, when the failure is step-local.

reason · string

Present only on failure: the located reason the proof did not check.

verified · boolean · required

True iff the derivation checks against the bundle’s own facts and rules.
