Assign a saved Location image as an unapproved candidate

location_reference_assign: permissions and generated input/output contracts.

location_reference_assign · Gateway release 0.8.3

Use one exact already-linked image for a Location role after agent inspection. Requires its current native assignment fingerprint and issued preview fingerprint. Keeps native distinct-role, locked-reference and membership checks; creates no images, jobs, credits or approval. New assignments remain unapproved; an identical existing assignment retains its current review state. A completed receipt replays under the same operationId. If the response is lost before a receipt is saved, read current roles/options to reconcile the saved state; never blindly resubmit assignment.

Required scopes: account:read, studio:write. Changes saved state or requests work; review the operation’s effects.

Availability depends on runtime configuration and the permissions granted to this connection. Use live MCP discovery as the authority.
