"""
Every CLI verb reaches its own code without falling over on a name.
`meshbay-node reload` shipped with `subprocess` unimported and crashed with a
NameError the first time it was typed. Python compiles that file happily —
`node --check validates syntax, not names` is already in CLAUDE.md about the
SPA, and it is the same class here: nothing in the module is wrong until the
branch runs.
So this walks every documented verb with the daemon stubbed out, and asserts
that the branch executes. It is deliberately shallow — what each command *does*
is tested in `test_ops.py` and `test_roster_pairing.py`. What this catches is a
branch nobody ever ran.

A bare `meshbay-node` — no subcommand, nothing dispatches, falls through to

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.
