// Why: a status fetched from another machine describes THAT machine, so `app` must too.
// `available` is the only desktop-window status that requires a live renderer owning the graph,
// which makes it the signal separating a real desktop app from a headless `serve`. Reporting a
// fixed running value while echoing the target's own window status produces a self-contradictory
// result, and readers acted on it — a remote GUI run was written off as headless (STA-4792).
// A pid is not knowable across the boundary, so it stays null.
