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. # Issue an authoring capability > Mints a new DRAFT policy version under `policy_id` — rules copied from `source_policy_version_id`, `created_by` set to the issuing human — and, in the same transaction, creates an authoring capability record bound to THAT minted version, a closed set of authoring actions, a set of granted source items and a validity window. The bound `policy_version_id` and `policy_version_number` are chosen by the server and returned; a caller cannot name them. Access is decided by two gates, in this order, both answering 403: the scope check runs first, so a principal without the api-keys:admin scope — including an authoring:capability carrier key — is refused FORBIDDEN and never reaches the second gate; a principal that HAS api-keys:admin but is an API key rather than a verified human session is then refused HUMAN_PRINCIPAL_REQUIRED. Only a verified human principal holding api-keys:admin reaches the handler. The subject key named in the body must hold the authoring:capability scope and must not hold policies:read or policies:write. Returns 404 AUTHORING_CAPABILITY_SOURCE_VERSION_NOT_FOUND when the source version is not a version of that policy in this tenant, and 409 AUTHORING_CAPABILITY_DRAFT_CONFLICT when the policy already has an open draft or submitted version, so no shell can be minted. ## OpenAPI ````yaml /api/openapi.json post /v1/authoring-capabilities openapi: 3.1.0 info: title: MeshQu API description: >- Governance infrastructure for policy-aware AI decisions.
