The "Clusev host" terminal was a shell inside the sidecar container (node@clusev, no
sudo, not the host). It is now a REAL SSH login into the host machine, like any fleet
server — so it shows the real root@<host> prompt with full rights.
- HostCredential (encrypted singleton) holds the host SSH login; a HostShell modal lets
the operator set host/port/user + password|key. The clear-text secret is never echoed
back; on edit a blank secret keeps the stored one, and switching auth method requires a
fresh secret (no password silently reused as a key).
- open('host') mints a kind=host token only when a login is configured, else opens the
setup modal; the internal resolve endpoint returns a server-shaped SSH spec (decrypted,
internal-net only) for kind=host, or 404 when unconfigured.
- compose: extra_hosts host.docker.internal:host-gateway so the sidecar reaches the host
sshd; Caddy now 404s /_internal/* at the public edge (the sidecar uses app:80 directly).
- rail gains a debounced search box past 5 servers; removed the now-obvious PTY hint line.
Browser-verified (R12): host tile shows "not configured" + gear → modal → SSH login as
root runs commands, zero console errors; search filters; resolve returns the host spec.
15 terminal tests pass.
