Show Cloud machine-list recovery instead of a stale 'unreachable' on return - #14777
Conversation
Add a list-status seam that reproduces today's panel decision, plus regression tests for #14483: going offline, returning with an interrupted read, a transient failure followed by success, a persistent failure on poll ticks, stale and cancelled completions, a hidden and shown panel, 401/402, and account or team changes. The offline, return, recovery and hidden-panel cases fail on this commit: offline is reported as a failed list read, and a recovery read keeps showing that failure with Retry until it answers. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Going offline wrote a transport error into the machine list's failure state, so every return from sleep showed "Cloud is unreachable" with Retry until the next read settled, even when recovery was quick. Offline is now its own state mirrored from the read coordinator, never a failed list read. Recovery reads (panel shown, back online, Retry, Refresh) show a transient failure as reconnecting until they settle; routine polls do not, so a persistent outage stays visible and actionable. The copy names the machine list rather than all of Cloud, and 401/402 keep their sign-in and upgrade actions. Fixes #14483 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Add all supported locale entries for the new machine-list strings.
Resources/Localizable.xcstrings lacks bs, da, it, km, nb, pl, pt-BR, ru, th, tr, and uk for all seven new keys. These String(localized:defaultValue:) calls therefore fall back to English for those locales. Add translated entries for every supported locale.

The poll clock keeps running through sleep, so the poll that fires on wake, or a read that spanned the sleep, can fail before the service answers again. Neither is a recovery read, so that failure stays on screen with Retry until the next poll 45 s later. Adds the injectable wake notification center these tests post to; nothing observes it yet.

The poll clock keeps running through sleep, so on wake the poll fires at once and a read that spanned the sleep expires. Either can fail before the service answers again, and as routine reads they left that failure on screen with Retry until the next poll. A wake is now a return, like coming back online: while the list is live (polling), the wake starts a recovery read, so an earlier transient failure reads as reconnecting until that read settles. A hidden or offline panel ignores the wake; it recovers when shown or back online. One read per wake, no loop and no delay. Refs #14483 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The sleep-spanning test released every held response at once, so it never saw the list between the failed read and the wake's recovery read. Answer only the requests already waiting and assert the list reads as reconnecting until the recovery read lands. The wake handler's comment also claimed an offline panel skips the wake; the guard checks polling only. Say what happens: offline, the coordinator refuses the read and the list keeps waiting for the network. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Fixes #14483.
Coming back to cmux after sleep or a network drop always showed "Cloud is unreachable" with a Retry button in the Machines panel, even though Cloud terminals reconnected within seconds. The machine list now says what is actually happening: "Waiting for network" while offline, "Reconnecting to Cloud…" while a recovery read replaces an earlier transient failure, and nothing once the list loads. A real, persistent failure still shows, with Retry, and the copy now names the machine list instead of claiming all of Cloud is down.
Why it happened
The banner wasn't reacting to a failed request. When the read coordinator reported the Mac offline,
MachinesPanelViewModel.applyNetworkChange(false)wrote a syntheticURLError(.notConnectedToInternet)intolastErrorDescription, setlistProblem = .unreachable, and marked the list as loaded. That is the same state a real control-plane failure produces, so the panel rendered it as the hard failure with Retry. On return,networkChanged(true)restarted polling, but the stored "failure" stayed on screen until the next list read settled. Terminals reconnect on their own path, which is why they worked under a banner saying Cloud was unreachable.What changed
isNetworkOfflinemirrors the coordinator's network event (the coordinator stays the sole network-state owner). It no longer toucheslistProblem,lastErrorDescriptionorhasLoadedOnce. A read that the coordinator expires for being offline (URLError.notConnectedToInternet; real transport errors arrive asVMClientError.backendUnreachable) is not recorded as a list failure.recoverList()marks a read as a recovery: showing the panel, coming back online, waking from sleep, Retry, toolbar Refresh, and the read that follows a machine action. While it runs, an earlier transient failure reads as "Reconnecting to Cloud…" with no Retry. When it settles, success clears the failure and failure shows it again. Routine 45 s polls don't set this, so a persistent outage stays steady instead of flickering.NSWorkspace.didWakeNotificationnow starts one recovery read while the list is being polled. A hidden or offline panel ignores the wake and recovers when it's shown or back online.refreshGeneration/scopeIdentifierfence. An account or team switch resets list status throughresetForAuthTransition(). Cached machines, terminals, selection and focus are untouched in every state.MachineListStatusPresentation(newMachinesListStatusViews.swift) drives the empty state, the compact notice above device rows, and the toolbar row, so they can't disagree. This also bringsMachinesPanelView.swiftdown from 741 to 608 lines.isLoadingbetween reads.The wake trigger is one read per wake, not a retry loop, and nothing is delayed. One limit: if the Mac wakes with its network interface up but the Cloud service not yet reachable (VPN or DNS still coming back), the wake's read can fail too, and the failure shows with Retry until the next poll or a Retry succeeds. Bootstrap retries stay with #11631, error classification with #11597/#11615, and per-gate toolbar actions with #12671. With cached machines on screen, a 401/402 still shows the generic "Machine list unavailable — showing last known" toolbar row, as before.
