+    A bare `meshbay-node` — no subcommand, nothing dispatches, falls through to
+    "start the daemon" at the bottom of main() — is exactly what the Windows W3
+    Startup .vbs and the service-mode Scheduled Task both run unattended. On a
+    fresh install neither has ever provisioned anything, so this is the first
+    thing that runs on the very first boot, quite possibly before the user has
+    ever opened the client.
+
+    This must fail closed, fast, and without a trace: no exception (nothing
+    catches one — the .vbs and the Scheduled Task are both headless, so an
+    uncaught crash is invisible and, run on every boot, an inert but permanent
+    fixture in the Task Scheduler history and Windows' own Application log).
+    Confirmed by hand first: measured under a second and zero bytes written
+    to disk against a real, empty %LOCALAPPDATA%.
+
+    load_config() already returns an empty Config when the path does not
+    exist rather than raising — this pins that main() then notices the empty
+    hub.username and exits before ever reaching NodeDaemon()/asyncio.run(),
+    so nothing here has to mock the daemon startup at all.
