The legacy fulfillment-queue detail document of the order named by uuid, legacy 24-hex id or ext:: (the channel's sales order): the populated order, every fulfillment order (oldest first, at most 100), the ACTIVE tenant-portal ones, the consolidated lines to pack, the mode and the summary, in the legacy shape (24-hex ids, the legacy field names and enums). A caller bound to channels reads only orders of those channels (404 otherwise). The preselected carrier comes without its adapter credentials.

Scope: channel:read, channel:write, fulfillment:write, shipments:write or admin. A permission group made before the Channel API scopes existed grants it as fulfillment-orders:manage.

Idempotency: not keyed; the request itself is safe to repeat.

Rate limit: read class, 6,000 requests per minute per tenant by default (write class 1,200). Every response carries X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset; a refusal is 429 rate_limited with Retry-After.
