 These limits define when the native chooser fits. They are current package constraints, not a general picker comparison or a task backlog.
 
 - **No cancellation of an open chooser** — the wire has no per-request abort, so a chooser already on the local display cannot be closed from the browser; a discarded settlement is ignored.
-- **Local Host carriers only** — the Electron dialog selects local paths; ordinary Web opens the Host chooser. Remote-browser and in-process deployments use the `-browse` composition. Platform failures surface through the owner's retryable folder dialog.
