							/**
 * REAL-composition coverage: a test-only cordis.yml booted through the
 * vendored Loader mounts the webserver row plus the adaptive chooser, and the
 * assertions observe the durable outcome — which backend entry the chooser
 * mounted into the Loader store, the capability the seam then serves, and
 * that disposing the chooser removes the mounted entry again (HMR safety),
 * joining the backend's own teardown before the disposer settles.
