A resume runs after vm.start() has already returned, so the machine is running and there is no fresh allocation to roll back. The provider can also name the network a VM is on before it fills in the address assigned on it, so an absent address in that payload is not a verdict on the machine.

Failing closed on a missing private address belongs to create, restore, and attach: the first two roll the allocation back, and attach reads the authoritative addresses and has no machine to hand over without a route. A wake has neither property. vm.start() has already returned, so the machine is running, and its payload can name the network before the platform fills in the address assigned on it. The wake now records that failure on its span and returns the running machine. openCmuxRemote stays the boundary that refuses an unreachable one.

New Cloud machines could be running with healthy services but fail to open in Nightly. Live debugging found both missing private-network announcements and competing app refreshes that returned an empty catalog before the first session snapshot was published. Restarting the app also restored desktop tabs with localhost ports owned by the previous process.
This follow-up to #12266 fixes those paths at their owners:
forcefor catalog reads.session.revisionaligned with the public cursor. Workspace, terminal, cursor, and unknown-resource conflicts remain rejected.Evidence and validation:
cloud-nightly-networkapp, the personal development account, this branch's local backend on port 4513, and real Freestyle VMs. Initial 4 GB and 8 GB creations loaded terminals and desktops. A third creation exposed the remaining refresh race; the fixes above address it. Automatic desktop restoration was verified after rebuilding, and the final create/refresh/restart loop is in progress.Build: cloud-nightly-network. Preview: Vercel.
This remains a draft until the final live loop passes. No merge has been performed.
Note
Medium Risk
Changes concurrent cloud graph publication and snapshot acceptance logic, plus VM lifecycle network prep—subtle race or stale-state bugs are possible though covered by new Swift/TS tests.
Overview
Fixes Cloud VM creation/catalog races, false snapshot conflicts, stale restored browser tabs, and Freestyle private-network reachability.
App (Swift): Adds
CloudProviderRefreshCoordinatorso each machine provider runs one refresh at a time—ordinary catalog reads share the in-flight pass, forced reads wait for a later pass, metadata updates invalidate and retry, andstop()cancels queued work. Refresh entry moves torefreshCurrentGraph/performRefreshwith protocolrefresh(force:)preserved for catalog reads.Snapshot semantics:
hasSameRevisionedContenttreats client list churn and live terminal title/size as non-revisioned; equal-cursor installs still update state when revisioned content matches. Document deltas keepsession.revisionin sync with the public cursor.Session restore: Restored port/desktop tabs call
reprojectRestoredBrowserPanes, reusing existing panel IDs while rebuilding hub forwards throughmaterializeBrowserPane(..., reusing:).Backend (Freestyle): New guest exec announces assigned private IPv4/IPv6 (GARP / neighbor advertisement) on create, restore, attach, and best-effort on resume; missing addresses fail closed on create/restore with rollback where applicable.
