📝 WalkthroughWalkthroughCloud navigation and Freestyle routes now prefer raw private-network addresses over WireGuard. Forwarded ports retain provider endpoint handling. The change also updates URL tests and documentation, removes link accent coloring, and removes machine-size controls from the New Machine sheet. ChangesDirect private-address navigation
Machine sheet cleanup
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR updates cloud port links to use private IP addresses directly, but related documentation still describes the removed hostname fallback, which could mislead future maintenance; this is a bounded follow-up rather than a merge blocker.

Use explicit forwarded-port metadata instead of hasPrefix("port:"). CmuxTuiSnapshotParser accepts any non-empty daemon browser ID and derives port from localhost URLs. A browser with ID port:example and URL http://localhost:3000 therefore satisfies the direct-navigation branch in materialize, bypassing the proxy path. The repository contains no daemon-ID namespace enforcement. Add typed metadata or reject reserved IDs at the parser boundary.

Asserts that a machine on a dual-stack VPC is dialed at its private IPv4, not its private IPv6. Fails against the current IPv6-first ordering. The tunnel routes the VPC's v4 prefix as a subnet, so it reaches any member as soon as that member exists. Its v6 path does not pick up members created after the tunnel came up, so a machine created into an established tunnel blackholes on its private v6 while answering on its private v4 — both work VM-to-VM inside the VPC, which is what made this look like a daemon fault rather than a routing one. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Reorders the private-network branch of freestyleCmuxRemoteRoute to prefer IPv4 over IPv6. The public fallback stays IPv6 — Freestyle allocates no public IPv4 at all — and private still never falls back to public. Every machine created after the WireGuard tunnel came up spent the full 60s connect timeout and surfaced as "Command timed out" / stuck at "connecting", while machines predating the tunnel connected in seconds. The daemon was healthy in both cases: it listens on *:1337, and the new machine answered on its private v4 and was reachable over both v4 and v6 from inside the VPC. Only the Mac's v6 path to it was dropped, because the tunnel routes the VPC's v4 prefix as a subnet but does not extend its v6 path to members added after setup. Preferring v4 also matches the app's own preferredPrivateAddress (v4 then v6), so the address shown and copied in the sidebar is now the same one the daemon is dialed on. Verified against the machine that had been timing out: it now links in 4.2s where it previously failed at 60s. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Fixes Cloud sidebar port links so they open the VM's private IP directly over the WireGuard tunnel instead of routing through the provider's port-forwarding proxy, which fails for arbitrary ports. Also dials VPC machines at their private IPv4 so machines created after the tunnel comes up connect instead of timing out.
