🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Any failure without an HTTP error now stops the link permanently.
terminal = typed.map { ... } ?? true marks every non-HTTP failure as terminal. That includes CloudMachineLink.LinkError.timedOut, ManagerError.retryLater ("still preparing remote access"), hub route failures and backendUnreachable.
After such a failure, two things happen:
- Line 180 rethrows
retryLateron every laterconnectedcall. - Line 449 reports
.errorfor as long as the entry exists.
Only resetRetry, disconnect, or a status/image change clears the entry. Before this change, the 15-second backoff let these transient failures recover on their own. Now a brief network drop keeps the machine unusable until the user acts.
The reverse case is also a problem. A retryable HTTP error sets lastFailure to nil, so the link-level backoff no longer applies. Only openCmuxRemote has the ledger. A machine that already has a stored fingerprint skips that call, so it gets no backoff at all.
Limit terminal state to typed refusals. Keep the timed backoff for everything else.
Proposed fix
- let terminal = typed.map { !$0.admitsAutomaticRetry || $0.requiresRecreate || $0.rejectsSession } ?? true
- if terminal {
- lastFailure[machineID] = LinkFailure(at: .now, error: text, typed: typed, terminal: true)
- } else {
- lastFailure[machineID] = nil
- }

Sources/Surfaces/CmuxTuiSurfaceProviderRegistry.swift:274
🎯 Functional Correctness | 🟠 Major | ⚡ Quick winProcess Cloud disablement before session rejection.
If a fleet-list request rejects the session and the user then disables Cloud, this guard returns before the Cloud-disabled branch can suspend existing providers and close their transports. The registry must handle Cloud availability independently of its rejected-session state. Move the Cloud-disabled transition ahead of this guard; keep the rejected-session guard for polling after Cloud remains enabled.

Summary
Cloud attach failures now honor the VM API error contract and stop automatic work when the server says a machine must be recreated or the session is rejected. The client decodes
status,error,retryable,retryAfterSeconds,phase, andtraceIdonce intoCloudVMHTTPError;VMClientcoalesces matching attach requests and applies one bounded exponential policy with aRetry-Afterfloor, jitter, an attempt/time budget, sticky terminal state, and an explicit reset seam. In-flight and retry state are fenced by the authenticated account/session generation/team.The registry, machine panel, restored-pane attach path, and attachment scheduler consume typed terminal/auth dispositions. A
vm_requires_recreateorvm_recreate_required409 stops that machine, presents localized Recreate and Copy Error actions, and no longer says Cloud service unavailable. A 401/403 stops registry and Machines panel polling until auth starts a new session. Both Recreate surfaces call the same shared launcher action, wired into the app target. Address-only machine route changes and explicit reset actions clear sticky retry state safely.Reproduction followed from issue #15107:
The regression suite covers the typed terminal contract, retryable/non-retryable admission, Retry-After floor, cap, machine-sticky reset, privacy-safe formatting, stopped attachment scheduling, pane Recreate state, registry 401 shutdown, Machines-panel 403 classification, legacy typed error assertions, and the shared socket privacy contract. I checked open PR #15089 before editing; this client change keeps both backend error spellings compatible while avoiding a second timer owner.
