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. # Seal a review submission > Assembles the ten ruled review-package components from a declared source corpus, a TOTAL disposition ledger and a bidirectional source-to-rule map, then seals them as an immutable review subject together with their exact canonical bytes. **RECORDS** which bytes a reviewer will be shown, in which named slot, under which policy version, in what order, at what time, attributed to which principal. **PROVES** byte equality under `meshqu-review-package/v1`, and nothing else. It does not prove source truth, source completeness, correct interpretation, human review or authority. **Source custody.** A manifest item naming custodian `urn:meshqu:custodian:meshqu` asserts that MeshQu HOLDS those bytes, and the seal refuses unless it does: the server looks for a finalised, read-back-verified object at that tenant's content address, in the same transaction that seals, and returns `source_item_not_finalised_in_custody` if there is none or `source_custody_attestation_disagrees_with_manifest` if the digest or length disagrees. Custody is MeshQu-controlled and tenant-scoped; upload the bytes through `/v1/source-uploads` first. Items naming any other custodian are unchecked here — MeshQu resolves no external locator and makes no claim about a custodian's store. The `availability` field sealed into the manifest stays `NOT_CHECKED` in every case, deliberately: availability is a CHECKED OBSERVATION made at a moment, and sealing one would freeze a time-varying fact into an immutable subject. Current availability is reported separately by `GET /v1/review-submissions/{submissionId}?check_source_availability=true`. **Resubmission creates a NEW subject.** Posting identical bytes again returns a different `id` with the next `submission_sequence`; it never returns or updates the earlier one. A judgment recorded against one subject can never be applied to another. Assembly failures return 422 carrying every violation found, each with its own distinct code (`unit_without_disposition`, `mapped_unit_without_rule`, `internal_control_claims_source_mapping`, and the rest of the closed set) and the offending identifier, so a defect class is diagnosable rather than reported as "validation failed". This route ratifies nothing, activates nothing and records no decision. It is not a receipt and no receipt binds its output. ## OpenAPI ````yaml /api/openapi.json post /v1/policies/{id}/versions/{version}/review-submissions openapi: 3.1.0 info: title: MeshQu API description: >- Governance infrastructure for policy-aware AI decisions.
