//! **Only the fetching medium ships the fetch worker** (lane cds4, plan row HOL-CDS-4;
//! rickard-e6 2026-11-01): the fetch job's code lives only in `holger-fetch-worker`, its own
//! worker build, laid as `sandbox/holger-fetch-worker.rootfs.tar` by the fetching downstream's
//! medium (`holger-downstream-installer`) alone. The one-way appliance, the estate's main, twin,
//! keep and front media never carry it, and the scan sandbox every box medium shares does not
//! name it. (Its tree guard: `server/cli/tests/one_way_ships_no_client.rs`.)
