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. # Return a sealed review submission to the author (OPD-130) > Marks a sealed submission RETURNED against a `CORRECT_AND_RESUBMIT` review record, so the agent that authored it can read the record under its capability and seal a revision that answers it. **A human governance act (ADR 0003).** Only a verified human-session principal is admitted. A credential that holds `policies:write` but is not a human session is refused 403 `HUMAN_PRINCIPAL_REQUIRED`; one that does not hold `policies:write` is refused 403 `FORBIDDEN` by the scope gate first, before the human check is reached. Two controls, two codes — neither renders as permission. **Who may.** The human whose session recorded the named record (`recording_reviewer`), or a tenant admin as the ruled FALLBACK (`tenant_admin`). Anyone else receives 403 `REVIEW_RETURN_NOT_REVIEWER_OR_ADMIN`. The fallback is ANY tenant admin — it does not mean a named second reviewer, and nothing checks that the admin read anything. `return_authority` records which door was taken. **The record must be a `CORRECT_AND_RESUBMIT` of THIS submission.** Another disposition is 409 `REVIEW_RECORD_NOT_CORRECT_AND_RESUBMIT`; a record that is not on this submission (or does not exist, or belongs to another tenant) is one 404 `REVIEW_RECORD_NOT_ON_SUBMISSION` covering all three, deliberately, so the route is not an existence oracle. **Once.** The machine is SEALED → RETURNED; a second return is 409 `REVIEW_SUBMISSION_ALREADY_RETURNED`. **What it changes and what it does not.** One append-only return row and one `review_submission_returned` audit row, on the same transaction. The sealed subject is untouched, the authoring capability stays valid, and the shell version stays draft. RECORDS that this human under this authority returned this subject naming this record. It does NOT establish that the author saw it, that the record is correct, or that anything was corrected. It is not a receipt and nothing here is signed. ## OpenAPI ````yaml /api/openapi.json post /v1/review-submissions/{submissionId}/return openapi: 3.1.0 info: title: MeshQu API description: >- Governance infrastructure for policy-aware AI decisions.
