🎯 Functional Correctness | 🟠 Major | ⚡ Quick winStart discovery when port support becomes available.
If a running machine changes from unsupported to supported, this line publishes
.notRequested. The nextperformRefreshskips the scan because it scans only states other than.notRequested. The expanded Ports row can then remain empty until another path changes the state.The structural root cause is an incomplete provider-owned discovery-demand transition. The provider is the single source of truth for this control state. Change the unsupported-to-supported transition to
.loading. This is the first migration cut that makes the visible-demand invariant explicit.Proposed fix
- portState = info.portDiscoveryState == .unsupported ? .notRequested : info.portDiscoveryState + portState = info.portDiscoveryState == .unsupported ? .loading : info.portDiscoveryStateAs per coding guidelines, Swift changes must name the invariant and source of truth. As per path instructions, correctness-critical control state must use one reliable source of truth.

Summary
Cloud Ports no longer presents a VM’s private IP as if it were a directly reachable website. The sidebar now shows discovered services as
:8000withOpen in cmux; VoiceOver still says “Port 8000.” Internalcontainerdanddockerdlisteners are filtered by process owner, so an idle VM does not show a misleading 404 port. Real application listeners remain discoverable, including apps using the same port number.The Cloud VPN page now uses the established onboarding layout: “Use Cloud machines from any app,” an explanation of the private network, a status card, first-time approval steps, and private-address guidance. Ports and Settings open the same shared pane. Cloud terminals, Ports, and Desktop continue to work without system VPN; only Connect activates the optional system-wide VPN.
sudo -n ss/netstatcommands where permitted, and falls back without prompting. No sudo rules, daemon startup arguments, terminal-host protocol, journal schema, or relay policy changed.Fixes #13234
