@rushstack/rush-daemon

The long-lived Rush workspace daemon host, including workspace-keyed listener bootstrap, protocol handshake and liveness control, a warm WorkspaceSession, and explicit serve/shutdown lifecycle APIs.

The package provides an opt-in rushd executable. Run it from a Rush workspace to start the host for the nearest rush.json; it does not change the default behavior of rush, rushx, or rush-pnpm.

The host loads RushConfiguration once before signaling readiness and keeps a headless file watcher active for the daemon lifetime. Its invalidation tracker retains changes while no clients are connected so a later request can reconcile them. The tracker starts with a conservative unknown invalidation covering session startup, and excessive distinct paths are compacted into the same full-workspace signal. Reusable operation graph, plugin, and input snapshot state can be supplied through the session component factory; the default session does not construct those command-specific resources while the reusable runner lifetime tracked by rushstack#5895 remains incomplete.
