A verification bundle binds ten sub-claims. > Quote the Decision Receipt definition byte-identically or not at all: 'A Decision Receipt is a signed, replayable record of how a consequential decision was made, created at the moment it happens and independently verifiable afterwards.' > Tamper evidence is two checks together: a content edit leaves the Ed25519 signature valid (it covers the stored integrity hash) and is caught by the integrity check; rewriting the hash then fails the signature. Never claim the signature alone detects edits. # Run a bounded synthetic case pack against a stored policy version > Executes an independently authored case pack against the rules stored on this policy version, in process, and returns the per-case results. **SYNTHETIC.** No decision, receipt, policy snapshot or audit row is created, nothing is signed and nothing is persisted. The response carries no `integrity_hash`, no signature and no decision id — it is not receipt-shaped and cannot be presented as a real evaluation. Non-billing, and rate-limited under the standard per-tenant/per-key tier. **RECORDS** what the stored rules did for each supplied case at the supplied `evaluation_time`, and how that compares to the case's expectation. **ESTABLISHES** deterministic agreement for the exact cases, rules, context and evaluator version exercised. It does NOT establish completeness beyond those cases, the truth of the case classifications, or source fidelity — the spike found one invented rule and one over-broad rule that oracle execution did not catch. **Five scoring states, not a pass rate.** `match` and `mismatch` are the scored outcomes. `unrepresentable` is an expected `NOT_APPLICABLE`: the evaluator has no verdict for "this policy does not apply", and its zero-rule ALLOW is retained as engine output rather than promoted to the policy outcome. `not_scored` is an expected `OUT_OF_SCOPE_INSUFFICIENT_EVIDENCE`, or a case with no expectation. `operational_failure` is an evaluator exception for that case — an indeterminate state, never an ALLOW. The summary reports five counts and no ratio, because the states do not roll up. 422 `CASE_PACK_CANDIDATE_DERIVED` refuses a pack that declares non-independent authorship AND whose every comparable expectation names exactly the rule codes the candidate fires. That check is narrow: it cannot detect a derived pack that declares `independent`, and coincidence with the firing set is also what a CORRECT independent oracle looks like. ## OpenAPI ````yaml /api/openapi.json post /v1/policies/{id}/versions/{version}/case-executions openapi: 3.1.0 info: title: MeshQu API description: >- Governance infrastructure for policy-aware AI decisions.
