What it means

 * consumers. An `external` specifier is either the package row it names
 * (`<pkg>/client` aliases the bare package) or a static-table name that adds no
 * graph edge.
 * @param entries - composed rows in scan order.
 * @returns the same rows reordered; scan order breaks every tie.
 * @throws {Error} when a row requests itself or when the module graph has a
 * cycle; the message lists the packages on it.
