Update an Origin Pull Request Review via the API

Update the body of a review with PATCH https://api.cursor.com/v1/origin/repos/{ownerSlug}/{repoName}/pulls/{pullNumber}/reviews/{reviewId}. Official reference: Origin API → Update Pull Request Review (OpenAPI OriginService_UpdatePullRequestReview).

Origin is in Early Beta and subject to change. Authenticate with an installation access token (oit_…) or a user access token that carries repository:pull_requests:reviews:write. Availability: Early Beta per the API overview.

Only the review author can update it; other callers receive PERMISSION_DENIED (HTTP 403). A review that does not belong to the named pull request returns NOT_FOUND (HTTP 404). Unsubmitted draft reviews can be updated too; a draft's response has no submittedAt. The new body replaces the prior body in full and must contain a non-whitespace character (INVALID_ARGUMENT otherwise). Pull request number is a JSON string. An unknown or unreachable pull returns 404. A 404 never distinguishes a missing pull from one your installation cannot reach.

Cost: 5 points against the principal budget (ordinary write).
