Unraid truncates the Server Name to 15 chars (NetBIOS limit). HOST2's real hostname is "unRAID-Jayred36" but master.conf's HOST2 (matching what Tailscale shows for this peer, since resolve_tailscale_ip() keys off the same value) is the untruncated "unRAID-Jayred365" — confirmed live, Tailscale's own Self.HostName on that machine is truncated too. vv_detect_host() did a strict case-insensitive match against the bare `hostname -s` output with no tolerance for this, so it always returned 'unknown' on HOST2. That silently broke the first-run wizard (Varaverk.page explicitly excludes 'unknown' from the "needs setup" check) even though host2.conf never existed, plus vv_partner_state() and vv_fallback_active() in monitor.php which independently reimplemented the same hostname comparison instead of calling vv_detect_host(). Fix: vv_detect_host() falls back to a prefix match when the local hostname is exactly 15 chars; vv_partner_state()/vv_fallback_active() now call vv_detect_host() instead of duplicating the comparison. Verified live on HOST2 — vv_detect_host() now returns 'host2', partner state correctly flags HOST2 as is_me, and the wizard-trigger condition now evaluates true.
