Problem

Pressing Create in the New Cloud Machine / Set Up Base sheet froze the whole window until the VM existed: the sheet is a window sheet (beginSheet) and it stayed up — Cancel and Create disabled — until cmux vm new / cmux vm base open exited (tens of seconds on Blaxel, longer for Desktop / Base). Nothing in that window was usable meanwhile.

What changed (ownership, not a bigger spinner)

A long-running create is no longer owned by a modal sheet's lifetime. It belongs to a model the Machines panel observes.

  • NewMachineModel.create() packs the choice into a MachineCreateRequest and hands it to an injected submit; the sheet finishes (.submitted) the moment the CLI run is launched. The only inline error left in the sheet is "could not launch" (sign-out raced the click) — by the time the create itself can fail, the sheet is gone.
  • MachineCreateCoordinator (@MainActor @Observable, new) owns every in-flight create: launches through the same CloudVMActionLauncher path the + button, palette and CLI use, keeps the launcher for Retry, classifies the outcome (created / createdButOpenFailed / failed), posts a notification through TerminalNotificationStore, publishes didChangeNotification, and drops rows on cmuxCloudVMAccessDidEnd. Late completions from a signed-out account are ignored.
  • Progress lives where the result appears. MachinesPanelViewModel mirrors the coordinator into pendingCreates; CloudTreeNodeBuilder renders them as a new pendingMachine row kind above the fleet with the sheet's own wording ("Creating…" / "Setting up Base…"). On failure the row turns red (Couldn't create machine / Couldn't set up Base), tooltip carries the CLI's first line, click shows the transcript, hover and context menu offer Retry Create / Show Error… / Copy Error / Dismiss. On success the row is removed and the fleet is re-read immediately so the real row takes its place. "Created but opening failed" drops the row (the machine is real and will list) and puts the reason in the panel's control bar plus a notification — it is never retried (a second run would mint a second machine).
  • No focus stealing. cmux vm new and cmux vm base open gain --focus <true|false> (same semantics as vm open --focus). The sheet passes --focus false: the machine still opens exactly as before (own workspace with terminal + desktop split; Base into its placeholder workspace) but the CLI never calls workspace.select, passes focus: false to surface.new_terminal, and skips re-focusing the shell after the desktop split. For Base, the pane is still focused when its workspace is the one already on screen (workspace.current check), so someone who waited there can type immediately. The success notification is anchored to the new workspace, so clicking it goes there.
  • Every entry point reaches the same flow: palette "New Cloud Machine…", Machines panel + (NewMachineSheetPresenter.presentNewMachine), and Set Up Base (AppDelegate.performCloudVMAction) all submit to the shared coordinator. The panel's operationDidBegin/End chrome hooks for create were removed — the row is the progress indicator now, and it is not tied to the panel instance that started it (a create started in one window shows in every Machines panel and survives the panel closing).

Trade-offs (stated, not absorbed)

  1. Success no longer switches you to the new machine. Today's behavior was "create → you are now in the machine's workspace". Now the workspace is created and bound but not selected; you get a notification ("calm-petrel is ready · click to go there") and the machine appears in the tree. This is the expert macOS behavior for a background job, but it is a visible change for someone who sits and waits. The CLI's own cmux vm new (agents, scripts) keeps foreground behavior unless --focus false is passed.
  2. The sheet lost its inline failure box + in-sheet Retry. Failures now live on the pending row (red, with Retry/Show Error/Copy Error/Dismiss) and in a notification. Rationale: the sheet is gone by the time the CLI fails; keeping a second error surface would split ownership.
  3. Existing-Base opens keep their old focus behavior. "Open Base" on an already-provisioned Base (no sheet) still runs vm base open without --focus false, so if you walk away during a wake it still focuses the Base workspace on completion. Deliberately left out of this PR to keep the blast radius to the create flow; it is a one-token follow-up.
  4. Legacy transports. Addressed in review: --focus false is now honored on the websocket and SSH fallback transports too (runVMPtyWebSocketWorkspace gates its workspace.select and honors pane focus, vmSSHOptions maps to noFocus).
  5. Notification anchoring. In-app notifications need a workspace to anchor to. Success anchors to the created workspace; failures anchor to the Base placeholder workspace (Base) or the currently selected workspace (new machine). If there is no workspace at all (no windows), the notification is skipped — the red row and the control-bar message still carry the error.
  6. The pending row's synthetic SurfaceMachineID (pending:<uuid>) only exists to keep CloudTreeNode.machine non-optional; the row is never expandable or draggable and has no catalog entry.

Verification

  • Two-commit regression: the first commit adds testCreateFinishesTheSheetBeforeTheMachineExists (fails on main: the sheet does not finish until the CLI exits); the second adds the fix. (History was rewritten once for the rotated v2.2 CLA policy — trailer-free commits, identical trees.)
  • Post-review hardening (CodeRabbit): --focus honored on websocket/SSH fallback transports; one effective paneFocus shared by the placeholder replacement and the real terminal; cmux vm new emits a stable OK machine=<id> token carried as CloudVMActionLauncher.Completion.machineId, so created-machine classification never depends on localized text (localized line kept as fallback for older bundled CLIs); the coordinator registers operations before launching (synchronous completions safe); create-failure transcripts are redacted once at storage through the launcher's shared sanitizer before reaching the row, control bar, notification, or clipboard.
  • New behavior tests (cmuxTests/MachineCreateCoordinatorTests.swift, Swift Testing, wired in the pbxproj): pending row with the sheet's wording; refused launch records nothing; success drops the row and the notice carries the new workspace; failure keeps the row with the CLI output, Retry relaunches the identical invocation; dismiss never drops a running row; created-but-open-failed drops the row and is not retriable; Base "Created Cloud VM …" output is not mistaken for a created machine; sign-out drops rows and ignores late completions; MachinesPanelViewModel mirrors the coordinator (also when mounted after the create started) and notes the created-but-unopened reason; CloudTreeNodeBuilder puts pending rows first, isEmpty is false while one runs, a phase change is a content-only (no reloadData) update.
  • cmuxTests/NewMachineModelTests.swift rewritten for the submit seam (--focus false in every invocation, Base request has no label, second Create ignored, launch refusal stays inline).
  • Hosted test-e2e.yml runs (cmux-unit, macOS 15): NewMachineModelTests and MachineCreateCoordinatorTests green; the first MachinesPanelPendingCreateTests run caught a real bug (the failure headline picked the CLI's "Created Cloud VM" progress line instead of the error), fixed, and all three suites re-dispatched on the current head. An AWS-builder cmux-unit build-for-testing verified the app target compiles (that Mac has no console session, so app-host tests run on the hosted lane).
  • Localization audit: every new user-facing string goes through String(localized:defaultValue:) with en + ja values in Resources/Localizable.xcstrings (15 new keys: machines.pending.*, machines.new.background.note*, machines.notification.*); existing keys reused for "Creating…", "Setting up Base…", "New Machine", "Base". CLI --help text is plain-text like the rest of the CLI usage strings. skills/cmux-cloud-vm/references/sidebar-parity.md updated for the sheet ↔ --focus false mapping.
  • No dev app was built or launched on this Mac (per task); no .github/swift-file-length-budget.tsv exists on this branch; .github/swift-warning-budget.tsv untouched.

Summary by cubic

Cloud machine creation no longer blocks the window. The New Machine and Set Up Base sheets used to remain modal until the CLI finished; they now close after launch, while successful background creates leave the current workspace selected.

  • A shared coordinator keeps operations alive across panels and sign-out, with notifications and redacted failure output.
  • Failed creates remain available for Retry, Show Error, Copy Error, or Dismiss; machines that open unsuccessfully are not retried.
  • Background creates pass --focus false, honored by TUI, websocket, and SSH paths; cmux vm new emits a stable machine ID for completion handling.
  • When the backend omits image kinds, the sheet defaults to the first servable kind or Base, while the picker still offers every kind.
  • Tests cover the coordinator flow, updated submit seam, uncapped plans, and fallback image-kind behavior.

Closes #11397.

Written for commit 1aeab63. Summary will update on new commits.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 0bc00

Background machine creation now permits overlapping long-running requests and continues across authentication changes. Unless creation identity is scoped to the full request and account, and accepted work is reconciled after sign-out, users could receive the wrong result or leave an untracked cloud machine behind; merge should wait for explicit owner acceptance or a fix.

Full details: Description check

Explanation

The description is detailed and on-topic. It covers the problem, implementation, trade-offs, verification, and linked issue. It does not include explicit Demo Video, Review Trigger, or Checklist sections from the template, but the core required information is present.

Full details: Linked Issues check

Explanation

The changes satisfy issue #11397 by dismissing the sheet immediately, continuing creation through a shared coordinator, showing pending and failed rows, surfacing errors, routing all entry points through the shared flow, and preventing unintended focus changes.

Full details: Out of Scope Changes check

Explanation

The localization, notification, CLI, transport, sign-out, documentation, and test changes directly support the background machine-creation behavior described in issue #11397. No unrelated changes are evident.

Full details: Cmux Swift Actor Isolation

Explanation

No new actor-isolation failure is introduced. MachineCreateCoordinator and MachinesPanelViewModel are @MainActor; notification callbacks use the main queue and MainActor.assumeIsolated; launcher completion handling uses Task { @mainactor in ... }. The new value models stay on the main-actor coordinator/UI path, while pure parser helpers are explicitly nonisolated. No service protocol or unisolated shared Sendable reference type was added. The lock-protected ProcessOutputCollector predates this PR.

Full details: Cmux Swift Blocking Runtime

Explanation

No custom-check failure was introduced. The PR adds no DispatchSemaphore, blocking wait, Thread.sleep, Task.sleep, delayed dispatch, polling loop, main-queue sync, or new manual lock in production Swift. Existing polling/sleep code in MachinesPanelViewModel and CLI/CMUXCLI+VMTui.swift, and the existing NSLock in CloudVMActionLauncher, are unchanged. The new refresh coalescing uses an explicit completion/state signal. The only new modal calls are user-triggered failure presentation (beginSheetModal/runModal), not synchronization for async work. The final PR commit changes test-only scaffolding.

Full details: Cmux Browser Automation Off-Main

Explanation

The check is not triggered. The actual PR diff (mainline parent 5383cb9 to 752f309, including the follow-up 0bc00c8) does not change Sources/TerminalController.swift, ControlCommandExecutionPolicy.swift, or ControlCommandExecutionPolicyTests.swift. The diff adds no browser.* socket command, WebKit wait, worker-router change, or policy classification change. Existing browser worker routing and policy coverage therefore remain unchanged debt.

Full details: Cmux Expensive Synchronous Load

Explanation

PASS. The PR diff adds no RestorableAgentSessionIndex.load(), SharedLiveAgentIndex, agent-history file read, JSON decoder, directory scan, or per-record syscall. The new @MainActor coordinator handles operation state and CLI process completions. Its failure parser scans only bounded in-memory CLI output, not an agent-owned file. The CLI changes add focus/workspace socket calls and do not modify agent-history loading. Existing loader call sites are unchanged and not worsened.

Full details: Cmux Cache Substitution Correctness

Explanation

PASS — The isolated PR diff introduces in-memory MachineCreateCoordinator.operations and pendingCreates only for transient pending-row UI. It does not persist, restore, undo, or snapshot that state. The existing SurfaceCatalog.shared.snapshot path remains a catalog read; the PR only adds pendingCreates to tree construction and keeps the fleet refresh, including a queued refresh when one is already running. The new focus logic uses a direct workspace.current request, not a cache. No changed production Swift, TypeScript, or JavaScript code swaps an authoritative read for an unhandled cached value.

Full details: Cmux No Hacky Sleeps

Explanation

PASS — The PR diff contains only Swift source/tests plus .xcstrings, .pbxproj, and Markdown files. It introduces no TypeScript, JavaScript, shell, or non-Swift build/runtime changes. The only timing-related matches are Swift comments, which this check excludes.

Full details: Cmux Algorithmic Complexity

Explanation

PASS — The PR adds no prohibited superlinear production algorithm. CloudTreeNodeBuilder.nodes adds one linear pass over pendingCreates and uses the existing dictionary/set lookups for fleet rows. MachineCreateCoordinator uses linear ID lookup for single-operation actions, not a batch rescan. Output parsing is linear and bounded by the launcher's 32 KiB collector. The new UI events do not add per-row sorting or filtering; existing tree scans were not expanded into a hotter path.

Full details: Cmux Swift Concurrency

Explanation

The PR adds new Combine app state at Sources/Cloud/MachinesPanelViewModel.swift:377: @Published private(set) var pendingCreates. This state tracks the new in-flight and failed machine-create lifecycle, and the view model remains ObservableObject while MachinesPanelView uses @StateObject. The PR also adds @Observable models, and the project targets macOS 14, so Observation is available. This is a changed-code match for the rule against new Combine state when Observation is available. No new background Dispatch queue or unowned lifecycle Task was found in the relevant production additions.

Resolution

Migrate MachinesPanelViewModel to Observation for its app state. Replace ObservableObject and its @Published properties with @Observable stored properties, including pendingCreates, and update MachinesPanelView from @StateObject to Observation storage such as @State (and @Bindable where bindings are required). Remove the new Combine publication for the create lifecycle rather than extending the legacy Combine model.

Full details: Cmux Swift `@Concurrent`

Explanation

PASS. The PR adds no nonisolated async function and no @concurrent annotation. New asynchronous work is absent from MachineCreateCoordinator; its coordinator and notifier methods are synchronous and explicitly @MainActor. The added createdMachineID, failure-display, and redaction helpers are synchronous nonisolated helpers, which the rule allows. MachinesPanelViewModel.performRefresh() and NewMachineSheetPresenter's fleet lookup remain existing actor-bound UI coordination paths; the refresh path awaits the actor-isolated VMClient and updates UI state on @MainActor. The diff introduces no invalid annotation or unhandled heavy async boundary.

Full details: Cmux Swift Package Boundaries

Explanation

The PR adds independently testable machine-create domain logic directly to the app target. MachineCreateRequest, MachineCreateOperation, MachineCreateCoordinator, and MachineCreateNotice are new Sources/Cloud types with Foundation/Observation-only core code, injected launch/notifier/clock dependencies, and state-transition tests using fakes. The tests cover launch registration, synchronous completion, retry, failure classification, parsing, redaction, and sign-out without constructing UI. cmux.xcodeproj/project.pbxproj places these files in the cmux app Sources phase and the tests in the host app test target. The feature commits add no SwiftPM target or Package.swift change. AppKit/UI files and app-lifecycle composition are allowed, but they do not account for this core state machine and its value models.

Resolution

Create a small macOS SwiftPM target named CmuxCloudVMCreation under Packages/macOS. Move the request/operation/outcome/finished value types and coordinator state machine, including pure parsing and failure classification, into that target. Give the package a public MachineCreateRequest as its first value API and a package-owned completion value or launch protocol instead of depending on CloudVMActionLauncher.Completion; inject the launcher, clock, auth-transition signal, and finish sink. Move the coordinator tests into the package test target so they run without the cmux app host. Keep CloudTree* views, MachineCreateRowActions, MachineCreateNotifier, AppDelegate, sheet wiring, localization/UI composition, and the CloudVMActionLauncher adapter in the app target. Wire the new package product into the app and tests.

Inline comments:
In `@CLI/cmux.swift`:
- Around line 12868-12869: Propagate the vmOpenShell focus parameter through
both fallback transports: pass its inverse into SSHCommandOptions.noFocus via
vmSSHOptions, and pass focus into runVMPtyWebSocketWorkspace so the
workspace.select call only runs when focus is requested. Preserve the existing
focused behavior while ensuring --focus false avoids selecting the workspace for
SSH and WebSocket paths.
- Around line 13079-13087: Update parseCloudVMFocusOption to reuse the existing
parseBoolString(_:) parser, preserving nil as true and mapping parser failures
to the command-specific CLIError message; remove the duplicated true/false
handling so this option also accepts the shared on/off values.

In `@CLI/CMUXCLI`+VMTui.swift:
- Line 466: Update the terminal-opening flow so the effective paneFocus value is
passed to surface.new_terminal instead of options.focus, keeping
workspace.cloud_vm_terminal_ready and terminal creation consistent for selected
and non-selected targets. Add regression coverage for both target-selection
cases.

In `@cmuxTests/MachineCreateCoordinatorTests.swift`:
- Line 343: Replace the Date() calls in the test fixture with the same fixed
Date(timeIntervalSince1970:) value for both startedAt operations, ensuring
deterministic timestamps in the affected test setup.

In `@Sources/Cloud/MachineCreateCoordinator.swift`:
- Around line 149-157: Update CloudVMActionLauncher.Completion and its callers
to carry the structured machine ID from CLI/cmux.swift instead of recovering it
from localized display output. Have MachineCreateCoordinator use that ID when
handling attach failures, and disable Retry when a nonzero exit provides no
machine ID; remove the localized parsing dependency around the existing
output-processing logic.
- Line 97: Update MachineCreateCoordinator.Launch to register the operation in
operations before invoking launch, ensuring synchronous completion handlers can
find and finish the operation; preserve the existing launch failure handling and
completion behavior.

Apply the same fix in `@Sources/Cloud/NewMachineModel.swift` at line 176: The
model reaches the same coordinator contract through its submit path.

In `@Sources/Cloud/MachineCreateOperation.swift`:
- Line 56: Sanitize CloudVMActionLauncher.Completion.output in the create flow
before MachineCreateOperation stores or displays it in MachineCreateNotice.body.
Update the path around headline(ofOutput:) so sanitization occurs before
truncation or presentation, reusing the existing sanitizer and ensuring provider
internals, credentials, headers, request IDs, and raw upstream messages are not
exposed.

Apply the same fix in `@Sources/Cloud/MachinesPanelViewModel.swift` at line 494:
The control-bar error must use the same safe summary.

Apply the same fix in `@Sources/Cloud/MachineCreateRowActions.swift` at line 57:
Row summaries, alerts, clipboard output, and accessibility text must use
sanitized diagnostics.

In `@Sources/Cloud/MachinesPanelViewModel.swift`:
- Line 496: Update the refresh coordination around refresh() and its refreshTask
completion handling so an overlapping refresh marks the state dirty while a
request is running, then performs exactly one follow-up refresh after the active
task completes. Preserve existing task cleanup and ensure the follow-up runs
after the completed request’s results are processed.

Regression test only; fails on main because create() keeps the sheet up
(and the window modal) until `cmux vm new` exits.

…11397)

The New Machine / Set Up Base sheet used to stay up (window-modal, Cancel
and Create disabled) until `cmux vm new` / `cmux vm base open` exited,
freezing the whole window for the length of the provision.

Ownership change: a create is no longer owned by the sheet's lifetime.
- NewMachineModel.create() packs the choice into a MachineCreateRequest,
  hands it to MachineCreateCoordinator, and finishes the sheet at once.
- MachineCreateCoordinator (@mainactor @observable) owns every in-flight
  create, keeps the launcher for Retry, classifies the outcome (created /
  created-but-open-failed / failed), notifies through the notification
  store, and drops rows on sign-out.
- MachinesPanelViewModel mirrors the coordinator into pendingCreates; the
  cloud tree renders them as pending machine rows ("Creating…" /
  "Setting up Base…", then a red row with Retry / Show Error / Copy Error /
  Dismiss) above the fleet. Created-but-unopened machines drop the row and
  put the reason in the control bar.
- `cmux vm new` and `cmux vm base open` gain `--focus <true|false>`; the
  sheet passes `--focus false` so the finished machine opens in its own
  workspace without selecting it or moving keyboard focus out of what the
  person is doing. The success notification's click goes there.

…redact create failures

CodeRabbit findings on #11421:
- Thread --focus into vmSSHOptions (noFocus) and runVMPtyWebSocketWorkspace
  (terminal_ready focus + gated workspace.select) so background creates do
  not steal focus on legacy transports either.
- Share the effective paneFocus between workspace.cloud_vm_terminal_ready
  and surface.new_terminal: the replacement pane, not just the placeholder,
  is focused when the person is already looking at the target workspace.
- parseCloudVMFocusOption routes through parseBoolString.
- vm new prints a stable 'OK machine=<id>' token; CloudVMActionLauncher
  parses it into Completion.machineId and MachineCreateCoordinator prefers
  it over the localized 'Created Cloud VM' line (kept as fallback), so a
  locale mismatch can never misclassify a created machine as retriable.
- MachineCreateCoordinator registers the operation before launching, so a
  synchronously delivered completion still resolves its row.
- Create failures are redacted once, at storage, through the launcher's
  sanitizer (first safe line + placeholder when blocked); progress/token
  lines are stripped so the reason leads every surface.
- Fixed fixture timestamps in tests; regression tests for sync completion,
  structured/fallback machine id, and redaction.

Claude-Session: https://claude.ai/code/session_01F4JxdiZVgqWWxvf8VYnu4L
createdMachineID(fromOutput:)/displayableFailureOutput are pure string
functions; as statics on a @mainactor class they were implicitly
actor-isolated and MachineCreateOperation.headline (nonisolated) could
not call them.

Inline comments:
In `@CLI/CMUXCLI`+VMTui.swift:
- Around line 405-407: Update the paneFocus/focus-application flow in the CLI
terminal creation path so workspace selection is evaluated atomically when focus
is applied, after the remote terminal and new surface operations complete,
rather than cached before them. Preserve options.focus behavior and ensure both
transitions—leaving and entering the requested workspace during the remote
operation—produce the correct final focus state; add regression coverage for
both cases.

In `@cmuxTests/MachineCreateCoordinatorTests.swift`:
- Line 341: Update the valid created-line fixtures in the
MachineCreateCoordinator tests to build their output through a helper that
formats the localized cli.vm.create.createdCloudVM template, then use that
helper for each applicable fixture instead of hard-coding the English prefix;
preserve the existing machine-ID assertions.
- Line 171: Replace the randomly generated workspaceID in the relevant
machine-creation test with a fixed UUID literal, ensuring the CLI fixture and
expected completion outcome use the same deterministic identifier.

In `@Sources/Cloud/MachineCreateCoordinator.swift`:
- Line 41: Remove the static shared singleton from MachineCreateCoordinator and
make coordinator ownership explicit by constructing it at the application
composition boundary and injecting the instance into every entry point that uses
it. Update those callers and initializers to accept the injected coordinator
while preserving existing notifier behavior and operation state handling.
- Line 193: Update the failure-message handling around the safe/generic
selection to return only localized, product-safe copy; do not expose backend
identifiers in CLI failure output. Keep raw CLI transcripts out of shared row
and notification state while preserving the existing generic fallback behavior.

In `@Sources/Cloud/MachinesPanelViewModel.swift`:
- Around line 496-498: Update createsDidChange so a successful refresh clears
the stale treeErrorDescription, or otherwise give the create-failure message an
explicit dismissal lifecycle; preserve the message when the create/open
operation fails and ensure performRefresh success cannot leave it displayed.
- Line 364: Update MachinesPanelViewModel to use Swift Observation with
`@Observable`, and migrate its SwiftUI ownership/access patterns to the
corresponding `@State` approach before adding pendingCreates. Remove the new
`@Published` declaration and preserve the existing pending-create state behavior
without relying on Combine unless a documented compatibility constraint requires
it.
- Line 496: Update the treeErrorDescription assignment in the relevant machine
operation flow to use a fixed product-safe control-bar message instead of
interpolating the machine ID or displayableFailureOutput. Keep detailed
provider/backend diagnostics confined to appropriately redacted logs.

In `@Sources/CloudVMActionLauncher.swift`:
- Line 205: Update the machine-ID parser in CloudVMActionLauncher to accept a
record only when the line’s first two tokens are “OK” and “machine=<id>”, rather
than matching machine= anywhere. Preserve extracting the ID from the second
token, and add a regression test covering failed output that contains machine=
in an error message.

Make background focus selection atomic.

paneFocus is computed once from workspace.current before workspace.cloud_vm_terminal_ready and surface.new_terminal. With options.focus == false, a selection change during these operations can make the cached value incorrect. The new pane can receive focus after the user leaves the target workspace or remain unfocused after the user enters it.

Move the selection check into the operation that applies focus, or add an atomic server-side precondition. Add regression coverage for both selection changes during the remote operation.

Use a fixed workspace identifier.

UUID() feeds the CLI fixture and the expected completion outcome. Replace it with a fixed UUID so failures are reproducible.

Proposed fix

Build valid created-line fixtures from the localized format.

This fixture hard-codes the English CLI prefix. MachineCreateCoordinator.createdMachineID(fromOutput:) derives that prefix from cli.vm.create.createdCloudVM. Under a translated app locale, this assertion returns nil. Add a helper that formats the localized template and use it for each valid Created Cloud VM … fixture in this suite.

createsDidChange sets treeErrorDescription and then calls refresh(). A successful performRefresh() clears lastErrorDescription, but it does not clear treeErrorDescription. The failure message can therefore remain after the next successful list refresh and show stale state.

Require the OK machine= record before accepting a machine ID.

This parser accepts machine=<id> anywhere in failed output. For example, Error: request rejected for machine=calm-petrel makes MachineCreateCoordinator classify the create as minted, remove the row, and disable Retry. Parse only a line whose first two tokens are OK and machine=<id>. Add a regression test for an error line containing machine=.

Proposed fix
-        for token in output.split(whereSeparator: \.isWhitespace) {
-            let string = String(token)
-            guard string.hasPrefix("machine=") else { continue }
-            let id = String(string.dropFirst("machine=".count))
+        for line in output.split(whereSeparator: \.isNewline) {

+            guard tokens.count >= 2,
+                  tokens[0] == "OK",

with the pre-#11397 two-argument run closure; on this branch the sheet
hands a single MachineCreateRequest to submit, so the merged test target

makeModel() uses imageKinds: [] by default. This is the same input used by testUnknownImageKindsStillOfferEveryKind, which expects .base at Line 192. This test instead requires --desktop, so the suite cannot pass consistently. Choose the intended default kind and update the conflicting assertion.

Do not treat an empty imageKinds response as support for every kind.

listVmImageKinds omits kinds that cannot resolve. The client then collapses missing and empty metadata to [], and selectableKinds returns all cases. The sheet can submit an unsupported kind, which resolveByKind rejects. Preserve field presence for the legacy fallback; fail closed when the field is present and empty.

String(localized:defaultValue:) returns the template, and replacingOccurrences(of: "%d", ...) only handles that exact token. Positional placeholders remain visible, and the integer does not use locale-specific formatting.

…rts no image kinds

NewMachineModel took the first of every kind when limits.imageKinds was
absent, which is Desktop; no provider ships a desktop image, so on an older
control plane the primary button failed closed with an image config error.
The kind the sheet opens on is now the first servable kind, else base, while
the picker still offers every kind.

Makes testUnknownImageKindsStillOfferEveryKind (added with the Freestyle
switch, #11566) pass; it fails on main for the same reason, where it
contradicts the desktop-by-default invocation test. This branch's default
invocation test now expects --base, with a separate case proving Desktop
still travels as --desktop when the backend serves it.

PresenceHeartbeatClient is @mainactor, so calling its static resolvedServiceURL

behavior is covered by the CLI-binary harness tests (ClaudeHookLiveDeliveryTargetTests

After #10781, worktreeDeviceID/worktreeFileID were both defaulted at the

* cli: cmux vm run/push/pull/wait and the cmux-cloud-vm agent skill

vm run routes a command to a cloud machine without naming one: sticky
per-directory binding, then an idle agent-pool machine, then a sleeper,
then a freshly provisioned pool machine. push/pull move files over the
exec channel (base64 chunks, SHA-256 verified, directories as tarballs);
wait blocks until ready and optionally wakes the machine. The skill lets
any coding agent drive machines from plain CLI.

* vm push: 64 KiB argv-bound chunks, no AppleDouble sidecars, line-safe progress

Live dogfood on Blaxel: a 512 KiB chunk base64-encodes past Linux's 128 KiB
per-argument limit ("argument list too long"), macOS tar shipped ._* files
onto the machine, and chunk progress ran together when stderr was captured.

* vm run: pool membership is the persisted id list, not the display label; review fixes

- The router now only drafts machines it provisioned itself (ids recorded in
  ~/.cmuxterm/vm-run-pool.json at create time, pruned when machines vanish); a
  user machine renamed agent-pool is never used. Test covers the impostor.
- Staging tarball is removed if reading it throws before the defer is armed.
- Push/pull chunk progress is localized (cli.vm.push.progress, cli.vm.pull.progress).
- vm --help, the usage contract, and the contract doc list open/ports/tools/
  handoff/promote-template, which the dispatcher already handled.
- Sticky-binding fixture uses a fixed instant, not the host clock.
- Skill recipes: --sync runs inside the synced dir (no remote $PWD), port
  readiness poll instead of sleep, eligibility filter instead of .vms[0],
  background test exit status captured to a status file.

* vm run: lock the pool store across processes; idempotent, run-scoped recipes

- updateVMRunPool does the read-modify-write under flock on a sibling lock
  file, so two routers provisioning at once both land in the store; covered by
  a two-process test against two mock sockets.
- Dev-server recipe reuses a live server or starts one with a workspace pidfile
  and log; test recipe uses per-run log/status paths written atomically.
- Document that --sync is additive.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* vm run: pool-store failures propagate; recipes validate the dev server and use unique run ids

- updateVMRunPool/saveVMRunPool throw on lock or write failure and createPoolVM
  reports the machine it provisioned but could not record, instead of a silent
  unlocked update.
- The dev-server recipe reuses a server only when the recorded pid is alive and
  owns :3000 (netstat -p), refuses to start a second server on a port someone
  else owns, and clears stale metadata.
- Test-run ids come from uuidgen, not the epoch second.
- Skill docs: cmux vm shell is a cmux-tui session now that machines run the
  cmux-tui remote daemon; agents keep working through vm run/exec.

* vm run: regression test — pruning a stale pool id must keep an id recorded after the vm.list snapshot

The mock socket records pool-2 while answering vm.list and returns a list that
predates it; the store must end up {pool-1, pool-2} with gone-1 pruned.

* vm run: prune only ids the pre-list snapshot saw as gone; product-level pool-store error

- Load the pool store before vm.list and subtract only the ids that snapshot
  lacks in the live list, instead of intersecting the locked set with a stale
  live snapshot, so a machine another vm run recorded meanwhile is never
  dropped from the pool.
- The provisioned-but-unrecorded error no longer interpolates the raw
  pool-store error (lock path, OS text); it keeps the machine id and the
  recovery commands.
- The unknown-size errors for vm run/route/agent list 24g, which
  parseCloudVMSize already accepts.

* cli: cmux vm <verb> --help prints the verb's own usage, offline

--help/-h short-circuited to the cmux vm overview for every verb, so the
option lists for run, route, agent, push, pull, wait, open, tree, workspace,
terminal, tui, prompt, and base (--size, --timeout, placement flags, --json
shapes) were unreachable without a running app and a usage error. A new
CLI/CMUXCLI+VMHelp.swift maps those verbs to their usage strings; the prompt
and base usages move out of the handler so they can be shared.

Also: the overview lists workspace and terminal, points at per-verb help,
no longer claims vm prompt --open accepts pi (the app supports
claude|codex|opencode), and the shell/desktop lines read in order.

docs/cli-contract.md: the vm/cloud usage probe now matches the binary (it
lacked prompt, so the no-socket contract lane was red), plus one offline
probe per routed verb and cmux surface --help.

* cmux-cloud-vm skill: the complete cmux Cloud CLI set, with a CI drift check

references/commands.md is now the single reference for every cmux vm verb
(and cmux cloud alias): usage, aliases, flags, --json shape, exit codes, the
socket method it calls, and the sidebar action it mirrors, grouped machine /
files / execution / routing / workspaces & terminals / surfaces & display /
checkpoints & forks / networking & ports / account & plan, plus the app's
vm.* socket table. Verbs that exist only in open PRs sit in one labeled
"In flight" section (#11324 cmux fork, #11347), so the skill never names
something an agent cannot run today; #11345 (vm terminal send|read|wait, the
single sidebar Close Workspace…) merged during this work and is folded in.

SKILL.md leads with vm run, then the glossary, cloud-vs-local, a need→verb
table, headless terminal loops, agent policy, and troubleshooting.
agent-workflows.md gains the headless-terminal recipe; openai.yaml describes
the same scope for Codex; Resources/cloud-agent-skill.md (the copy vm prompt
installs) no longer disagrees with the CLI (24g, vm base open, plain-terminal
shell, ~30 s exec, vm wait/handoff/prompt/ssh-info/promote-template,
fork/restore flags, per-verb --help).

tests/test_cloud_vm_skill_coverage.py (workflow-guard-tests lane) parses the
vm dispatcher, the workspace/terminal/surface sub-verbs, the usage line, the
docs/cli-contract.md probe, and the advertised vm.* methods, and fails when
the skill and the CLI disagree in either direction or when an in-flight verb
has already shipped.

Localization audit: CLI help/usage text follows the English-only CLI help
convention; no Settings, menu, or web strings touched.

* vm run: re-read the pool after pruning so a concurrently recorded machine is eligible; full -h probe needles

A machine another vm run recorded between this run's pool load and vm.list
(and that the list carries) was not in the pre-list snapshot, so it was
ineligible for this run and could push it toward a needless provision or a
false would_provision from vm route. The eligible set is now the post-prune
store intersected with the live list.

docs/cli-contract.md: the -h / cloud run / upload probes name the full usage
line, same as their --help siblings.

* cmuxTests: align CFFIXED_USER_HOME with a test's HOME whenever the child inherits a CF home redirect

On the hosted e2e lane the console session forwards CFFIXED_USER_HOME without
CMUX_APP_HOST_ISOLATION_REQUIRED, so every CLI the process harness spawned
resolved NSHomeDirectory() to the runner's home and ignored the test's HOME:
the vm run pool/binding stores, SSH ~ expansion, and hook installs all landed
outside the per-test home (126 failures across the class, including main's
own testVMRunReusesIdlePoolMachine). The harness now aligns
CFFIXED_USER_HOME with HOME when either the isolation flag is set or a
CFFIXED_USER_HOME redirect is already present.

* vm run: resolve the router's state home from $HOME; harness pins CFFIXED_USER_HOME to a test's HOME

NSHomeDirectory() resolves through Core Foundation (CFFIXED_USER_HOME, then
the passwd entry) and ignores a HOME override — the comment claiming it honors
$HOME was wrong. So the pool and binding stores, documented as HOME-relative,
went to the real ~/.cmuxterm in every redirected run, and the router tests
(main's own included) only passed under CI's app-host isolation, where the
harness aligned CFFIXED_USER_HOME. Reproduced on a fleet Mac's GUI session
(274 tests, 120 failures) with the same signature as the hosted lane.

- CLI: vmRunStateHomeDirectory() prefers a non-empty $HOME, else
  NSHomeDirectory(); both store URLs use it.
- cmuxTests: isolatedCLIChildEnvironment pins CFFIXED_USER_HOME to the

  app-host isolation flag), so every spawned CLI agrees with the test.

* ci: mark the CLA policy guard's GitHub-hosted runner as required so the self-hosted guard passes

#11387/#11407 added cla-policy-guard.yml on a bare ubuntu-24.04 runner, which
tests/test_ci_self_hosted_guard.sh forbids without the github-hosted-required
marker; workflow-guard-tests has been red on main since. The guard is a
base-controlled pull_request_target workflow, so a GitHub-hosted runner is
the intended trust boundary — same marker the browser, npm-provenance, and
attestation jobs carry.

* skill + vm new help: no desktop image ships today; Freestyle default; paid plans uncapped

#11566 removed Blaxel and flipped vm new to shell-only-by-default but left
the cmux vm overview claiming desktop-by-default — the overview now matches
the dispatcher. The skill (SKILL.md, commands.md, agent-workflows.md, the
bundled cloud-agent-skill.md) drops the xfce/noVNC/CUA desktop claims,
documents --desktop failing closed until a desktop image lands, the
e2b|freestyle|daytona provider set with Freestyle as the server-side default,
and #11580's uncapped paid plans (the 'no limit' plan meter line).

* skill: note #11609's grow-only sizing under In flight

* ci: make the #11524 release-origins gate pass the Linux guard harness (fixes #11757)

Three gaps broke workflow-guard-tests on every merge ref since #11524:
- verify-ios-release-origins.sh read plists only via /usr/libexec/PlistBuddy,
  which does not exist on the Linux guard lane, so every key read <absent>
  and the gate failed closed. It now falls back to python3 plistlib when
  PlistBuddy is missing; the absolute path stays first so PATH can never
  shadow the reader in a release lane.
- The fake archives in tests/test_ios_appstore_lane_identity.py never baked
  the production-origin keys a real Release build carries; both fixture
  writers now stamp CMUXAuthEnvironment/CMUXApiBaseURL/CMUXIrohBrokerBaseURL/
  CMUXPresenceBaseURL.
- The isolated-repo fixture copied upload-testflight.sh but not the new lib
  script it calls, so the auto-version lane failed on a missing file.

tests/test_ios_appstore_lane_identity.py: 77/77 ok, exit 0 locally (macOS
PlistBuddy path); the plistlib path verified standalone and by CI's Linux lane.

Newest main marked two ISO8601DateFormatter statics nonisolated (a warning:
the type is not Sendable) and left PresenceHeartbeatClient.resolvedServiceURL
main-actor-isolated while PresenceHeartbeatClientTests calls it from
nonisolated Swift Testing contexts, which stops cmuxTests compiling on every
app-host shard. The formatters become Date.ISO8601FormatStyle constants
(Sendable, same accepted formats) parsed via Date(_:strategy:), and the
resolver — a pure function of its environment/defaults arguments over
nonisolated PresenceSettings/AuthEnvironment statics — becomes nonisolated.

* skill: document cmux vpn hosts, extend the drift check to the vpn dispatcher, refresh the in-flight facts from freestyle-vm-primitives

cmux vpn hosts landed with #11626 but the skill's vpn section stopped at
revoke; the coverage check only parsed the vm dispatcher, so nothing
caught it. The check now parses runVPNCommand the same way and fails on
a vpn verb the reference misses or invents (it flagged the in-flight
section's own wording during this change).

The in-flight section also claimed a hosts verb family was arriving with
the guest-CLI work — wrong on both ends: vpn hosts already ships here,
and freestyle-vm-primitives has no vm hosts verb. Replaced with what
that branch actually adds today: the guest cmux shim + in-VM notify
bridge, vm help, the screen->display catalog kind rename, and the
vm tree --refresh fleet re-read.

* skill: re-ground on the desktop image and live private-path port opens from newest main

#11776 baked the TigerVNC desktop into the devbox image and #11756/#11776
gave the Freestyle driver its first openPort — the URL is the machine's
private VPC address behind the WireGuard tunnel, never a public ingress.
So --desktop no longer fails closed, vm desktop works on desktop-kind
machines (private address on 6901, vpn required, base machines exit 1),
and the port verbs are no longer dormant. The reference, SKILL.md,
agent-workflows, and the bundled cloud-agent-skill now say so, and the
in-flight notes shrink to what freestyle-vm-primitives still adds: the
public TLS-edge previews on tokened subdomains and the vm-new
desktop-by-default flip (vm base open has been desktop-default since
#10948 — the CLI's two kind parsers differ today, which docs/cli-contract.md
already papers over by describing the flipped default).

* skill: teach the delegation mission — persistence past the closed laptop, staged machine workspaces

The point of the CLI is a local agent delegating work to the cloud, so
the skill now says so up front (sessions live in the machine's daemon
and survive the Mac disconnecting; reattach from any signed-in Mac) and
gains the staged-workspace recipe: compose a named machine workspace's
terminals headlessly with surface new-terminal --remote-workspace,
verify with vm tree --json, and hand the user one click that opens the
whole thing. Honest about today's two edges: vm workspace new always
opens a local workspace as a side effect, and vm agent cannot target a
workspace (use surface new-terminal with a login shell instead).

* cli+skill: the 20g plan machine is the only size preset — say so everywhere

Main's plan-machine change (#11756/#11783) reduced cloudVMSizeAliases to
20g/20gb (or raw MB), but the error strings and usage lines still
advertised the retired 2g-32g ladder — ours worse, still carrying the
24g we added when that preset existed. vm run/route/agent unknown-size
errors, the vm new usage and unknown-flag text, docs/cli-contract.md's
vm new row (matching the freestyle-vm-primitives wording to keep that
merge clean), and every skill mention now name 20g (the 5 vCPU / 20 GB
/ 200 GB plan machine) or raw MB — matching parseCloudVMSize instead of
misleading an agent into a rejected --size 8g.

Also taken in this merge: main's #11754 landed the Linux iOS-guard fix
this branch had been carrying, so those files resolve to main's
(77/77 local pass).

* fix: silence the guard-condition trailing-closure warning Xcode 26.3 added

The critical-pressure teardown hardening (via main) left two compactMap
trailing closures inside postAggregateMemoryPressureWarning's guard
condition; Xcode 26.3's compiler warns 'trailing closure in this context
is confusable with the body of the statement' on both (76:41, 77:41),
which fails the warning-budget lane with actual=2 budget=0 — on main's
own runs too (run 33716921978 shows the same +2). Parenthesized closure
arguments are the fix the diagnostic prescribes; no behavior change.

* fix: adapt the Base create launch to the 3-argument coordinator Launch

Two green PRs crossed on main: #10773 added a 2-argument
MachineCreateCoordinator.start call in the Base sheet flow while #11773
changed Launch to (arguments, progress, completion) for the pending
row's live output — main has not built the combination yet, and the
first tree containing both fails with 'contextual closure type expects
3 arguments'. The Base flow now takes the progress handler and threads
it through launchCloudVMBaseOpen into CloudVMActionLauncher's existing
onOutput, so Base creates stream output to the pending row exactly like
the New Machine sheet's flow in NewMachineSheetPresenter.

Two fixes for main's own test file (byte-identical there, so main's

MachinesPanelPendingCreateTests suite called Self.newMachineRequest for
a helper that lives on MachineCreateCoordinatorTests — qualifying the
type fixes the lookup and gives the trailing 'name: nil' its context.

* cli: cmux vm run/push/pull/wait and the cmux-cloud-vm agent skill

vm run routes a command to a cloud machine without naming one: sticky
per-directory binding, then an idle agent-pool machine, then a sleeper,
then a freshly provisioned pool machine. push/pull move files over the
exec channel (base64 chunks, SHA-256 verified, directories as tarballs);
wait blocks until ready and optionally wakes the machine. The skill lets
any coding agent drive machines from plain CLI.

* vm push: 64 KiB argv-bound chunks, no AppleDouble sidecars, line-safe progress

Live dogfood on Blaxel: a 512 KiB chunk base64-encodes past Linux's 128 KiB

onto the machine, and chunk progress ran together when stderr was captured.

* vm run: pool membership is the persisted id list, not the display label; review fixes

- The router now only drafts machines it provisioned itself (ids recorded in
  ~/.cmuxterm/vm-run-pool.json at create time, pruned when machines vanish); a
  user machine renamed agent-pool is never used. Test covers the impostor.
- Staging tarball is removed if reading it throws before the defer is armed.
- Push/pull chunk progress is localized (cli.vm.push.progress, cli.vm.pull.progress).
- vm --help, the usage contract, and the contract doc list open/ports/tools/
  handoff/promote-template, which the dispatcher already handled.
- Sticky-binding fixture uses a fixed instant, not the host clock.
- Skill recipes: --sync runs inside the synced dir (no remote $PWD), port
  readiness poll instead of sleep, eligibility filter instead of .vms[0],
  background test exit status captured to a status file.

* vm run: lock the pool store across processes; idempotent, run-scoped recipes

- updateVMRunPool does the read-modify-write under flock on a sibling lock
  file, so two routers provisioning at once both land in the store; covered by
  a two-process test against two mock sockets.
- Dev-server recipe reuses a live server or starts one with a workspace pidfile
  and log; test recipe uses per-run log/status paths written atomically.
- Document that --sync is additive.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* vm run: pool-store failures propagate; recipes validate the dev server and use unique run ids

- updateVMRunPool/saveVMRunPool throw on lock or write failure and createPoolVM
  reports the machine it provisioned but could not record, instead of a silent
  unlocked update.
- The dev-server recipe reuses a server only when the recorded pid is alive and
  owns :3000 (netstat -p), refuses to start a second server on a port someone
  else owns, and clears stale metadata.
- Test-run ids come from uuidgen, not the epoch second.
- Skill docs: cmux vm shell is a cmux-tui session now that machines run the
  cmux-tui remote daemon; agents keep working through vm run/exec.

* vm run: regression test — pruning a stale pool id must keep an id recorded after the vm.list snapshot

- Load the pool store before vm.list and subtract only the ids that snapshot
  lacks in the live list, instead of intersecting the locked set with a stale
  live snapshot, so a machine another vm run recorded meanwhile is never
  dropped from the pool.
- The provisioned-but-unrecorded error no longer interpolates the raw
  pool-store error (lock path, OS text); it keeps the machine id and the
  recovery commands.
- The unknown-size errors for vm run/route/agent list 24g, which

* cli: cmux vm <verb> --help prints the verb's own usage, offline

--help/-h short-circuited to the cmux vm overview for every verb, so the
option lists for run, route, agent, push, pull, wait, open, tree, workspace,
terminal, tui, prompt, and base (--size, --timeout, placement flags, --json
shapes) were unreachable without a running app and a usage error. A new
CLI/CMUXCLI+VMHelp.swift maps those verbs to their usage strings; the prompt
and base usages move out of the handler so they can be shared.

Also: the overview lists workspace and terminal, points at per-verb help,
no longer claims vm prompt --open accepts pi (the app supports
claude|codex|opencode), and the shell/desktop lines read in order.

docs/cli-contract.md: the vm/cloud usage probe now matches the binary (it
lacked prompt, so the no-socket contract lane was red), plus one offline
probe per routed verb and cmux surface --help.

* cmux-cloud-vm skill: the complete cmux Cloud CLI set, with a CI drift check

references/commands.md is now the single reference for every cmux vm verb
(and cmux cloud alias): usage, aliases, flags, --json shape, exit codes, the
socket method it calls, and the sidebar action it mirrors, grouped machine /
files / execution / routing / workspaces & terminals / surfaces & display /
checkpoints & forks / networking & ports / account & plan, plus the app's
vm.* socket table. Verbs that exist only in open PRs sit in one labeled
"In flight" section (manaflow-ai#11324 cmux fork, manaflow-ai#11347), so the skill never names
something an agent cannot run today; manaflow-ai#11345 (vm terminal send|read|wait, the
single sidebar Close Workspace…) merged during this work and is folded in.

SKILL.md leads with vm run, then the glossary, cloud-vs-local, a need→verb
table, headless terminal loops, agent policy, and troubleshooting.
agent-workflows.md gains the headless-terminal recipe; openai.yaml describes
the same scope for Codex; Resources/cloud-agent-skill.md (the copy vm prompt
installs) no longer disagrees with the CLI (24g, vm base open, plain-terminal
shell, ~30 s exec, vm wait/handoff/prompt/ssh-info/promote-template,
fork/restore flags, per-verb --help).

tests/test_cloud_vm_skill_coverage.py (workflow-guard-tests lane) parses the
vm dispatcher, the workspace/terminal/surface sub-verbs, the usage line, the
docs/cli-contract.md probe, and the advertised vm.* methods, and fails when
the skill and the CLI disagree in either direction or when an in-flight verb
has already shipped.

Localization audit: CLI help/usage text follows the English-only CLI help
convention; no Settings, menu, or web strings touched.

A machine another vm run recorded between this run's pool load and vm.list

ineligible for this run and could push it toward a needless provision or a
false would_provision from vm route. The eligible set is now the post-prune

* cmuxTests: align CFFIXED_USER_HOME with a test's HOME whenever the child inherits a CF home redirect

On the hosted e2e lane the console session forwards CFFIXED_USER_HOME without
CMUX_APP_HOST_ISOLATION_REQUIRED, so every CLI the process harness spawned
resolved NSHomeDirectory() to the runner's home and ignored the test's HOME:
the vm run pool/binding stores, SSH ~ expansion, and hook installs all landed
outside the per-test home (126 failures across the class, including main's
own testVMRunReusesIdlePoolMachine). The harness now aligns
CFFIXED_USER_HOME with HOME when either the isolation flag is set or a
CFFIXED_USER_HOME redirect is already present.

* cmux-cloud-vm skill: provisioning is gated to paid plans (vm_requires_pro) after manaflow-ai#11332

* vm run: resolve the router's state home from $HOME; harness pins CFFIXED_USER_HOME to a test's HOME

NSHomeDirectory() resolves through Core Foundation (CFFIXED_USER_HOME, then
the passwd entry) and ignores a HOME override — the comment claiming it honors
$HOME was wrong. So the pool and binding stores, documented as HOME-relative,
went to the real ~/.cmuxterm in every redirected run, and the router tests
(main's own included) only passed under CI's app-host isolation, where the
harness aligned CFFIXED_USER_HOME. Reproduced on a fleet Mac's GUI session
(274 tests, 120 failures) with the same signature as the hosted lane.

- CLI: vmRunStateHomeDirectory() prefers a non-empty $HOME, else
  NSHomeDirectory(); both store URLs use it.
- cmuxTests: isolatedCLIChildEnvironment pins CFFIXED_USER_HOME to the
  supplied HOME unconditionally (XDG_CONFIG_HOME still only under the
  app-host isolation flag), so every spawned CLI agrees with the test.

* ci: mark the CLA policy guard's GitHub-hosted runner as required so the self-hosted guard passes

manaflow-ai#11387/manaflow-ai#11407 added cla-policy-guard.yml on a bare ubuntu-24.04 runner, which
tests/test_ci_self_hosted_guard.sh forbids without the github-hosted-required
marker; workflow-guard-tests has been red on main since. The guard is a
base-controlled pull_request_target workflow, so a GitHub-hosted runner is
the intended trust boundary — same marker the browser, npm-provenance, and
attestation jobs carry.

* skill + vm new help: no desktop image ships today; Freestyle default; paid plans uncapped

manaflow-ai#11566 removed Blaxel and flipped vm new to shell-only-by-default but left
the cmux vm overview claiming desktop-by-default — the overview now matches
the dispatcher. The skill (SKILL.md, commands.md, agent-workflows.md, the
bundled cloud-agent-skill.md) drops the xfce/noVNC/CUA desktop claims,
documents --desktop failing closed until a desktop image lands, the
e2b|freestyle|daytona provider set with Freestyle as the server-side default,
and manaflow-ai#11580's uncapped paid plans (the 'no limit' plan meter line).

Verbatim from open manaflow-ai#11586 (Blaxel-removal migration applies on a fresh
database via ::text enum comparisons — same fix as manaflow-ai#11582 — plus the
cmuxTuiDaemon shell wiring and the freestyle shell-repair test removal it
replaces with vm-cmux-tui coverage), and the pricing-page test updated to
the 'Unlimited' concurrent-VMs copy manaflow-ai#11580 shipped. Whichever lands first,
the rest merge clean.

web/services/vms/desktopWrapper.ts and the workflow answer 'open-port is not
supported by this deployment'; the CLI verbs exist and are kept documented,

* cloud: clear the three main-actor isolation warnings manaflow-ai#11421 left over budget

tests-build-and-lag has been red since manaflow-ai#11421: finishedUserInfoKey referenced
from the notification observer's Sendable closure, and .shared used as a
default argument (default values evaluate in a nonisolated context) in
MachinesPanelViewModel.init and NewMachineSheetPresenter.presentNewMachine.
The string constant becomes nonisolated; the default arguments become
optional and resolve to .shared inside the main-actor bodies. Verified on a
fleet builder: cmux-unit build-for-testing succeeds with zero warnings in
these files. No behavior change; explicit-coordinator callers (tests)
unchanged.

* skill: note manaflow-ai#11609's grow-only sizing under In flight

* ci: make the manaflow-ai#11524 release-origins gate pass the Linux guard harness (fixes manaflow-ai#11757)

Three gaps broke workflow-guard-tests on every merge ref since manaflow-ai#11524:
- verify-ios-release-origins.sh read plists only via /usr/libexec/PlistBuddy,
  which does not exist on the Linux guard lane, so every key read <absent>
  and the gate failed closed. It now falls back to python3 plistlib when
  PlistBuddy is missing; the absolute path stays first so PATH can never
  shadow the reader in a release lane.
- The fake archives in tests/test_ios_appstore_lane_identity.py never baked
  the production-origin keys a real Release build carries; both fixture
  writers now stamp CMUXAuthEnvironment/CMUXApiBaseURL/CMUXIrohBrokerBaseURL/
  CMUXPresenceBaseURL.
- The isolated-repo fixture copied upload-testflight.sh but not the new lib
  script it calls, so the auto-version lane failed on a missing file.

tests/test_ios_appstore_lane_identity.py: 77/77 ok, exit 0 locally (macOS
PlistBuddy path); the plistlib path verified standalone and by CI's Linux lane.

* cloud: Sendable ISO8601 parsing in VMClient; nonisolated presence URL resolver

Newest main marked two ISO8601DateFormatter statics nonisolated (a warning:
the type is not Sendable) and left PresenceHeartbeatClient.resolvedServiceURL
main-actor-isolated while PresenceHeartbeatClientTests calls it from
nonisolated Swift Testing contexts, which stops cmuxTests compiling on every
app-host shard. The formatters become Date.ISO8601FormatStyle constants
(Sendable, same accepted formats) parsed via Date(_:strategy:), and the
resolver — a pure function of its environment/defaults arguments over
nonisolated PresenceSettings/AuthEnvironment statics — becomes nonisolated.

* skill: document cmux vpn hosts, extend the drift check to the vpn dispatcher, refresh the in-flight facts from freestyle-vm-primitives

cmux vpn hosts landed with manaflow-ai#11626 but the skill's vpn section stopped at
revoke; the coverage check only parsed the vm dispatcher, so nothing
caught it. The check now parses runVPNCommand the same way and fails on
a vpn verb the reference misses or invents (it flagged the in-flight
section's own wording during this change).

The in-flight section also claimed a hosts verb family was arriving with
the guest-CLI work — wrong on both ends: vpn hosts already ships here,
and freestyle-vm-primitives has no vm hosts verb. Replaced with what
that branch actually adds today: the guest cmux shim + in-VM notify
bridge, vm help, the screen->display catalog kind rename, and the
vm tree --refresh fleet re-read.

* skill: re-ground on the desktop image and live private-path port opens from newest main

manaflow-ai#11776 baked the TigerVNC desktop into the devbox image and manaflow-ai#11756/manaflow-ai#11776
gave the Freestyle driver its first openPort — the URL is the machine's
private VPC address behind the WireGuard tunnel, never a public ingress.
So --desktop no longer fails closed, vm desktop works on desktop-kind
machines (private address on 6901, vpn required, base machines exit 1),
and the port verbs are no longer dormant. The reference, SKILL.md,
agent-workflows, and the bundled cloud-agent-skill now say so, and the
in-flight notes shrink to what freestyle-vm-primitives still adds: the
public TLS-edge previews on tokened subdomains and the vm-new
desktop-by-default flip (vm base open has been desktop-default since
manaflow-ai#10948 — the CLI's two kind parsers differ today, which docs/cli-contract.md
already papers over by describing the flipped default).

* skill: teach the delegation mission — persistence past the closed laptop, staged machine workspaces

The point of the CLI is a local agent delegating work to the cloud, so
the skill now says so up front (sessions live in the machine's daemon
and survive the Mac disconnecting; reattach from any signed-in Mac) and
gains the staged-workspace recipe: compose a named machine workspace's
terminals headlessly with surface new-terminal --remote-workspace,
verify with vm tree --json, and hand the user one click that opens the
whole thing. Honest about today's two edges: vm workspace new always
opens a local workspace as a side effect, and vm agent cannot target a
workspace (use surface new-terminal with a login shell instead).

* cli+skill: the 20g plan machine is the only size preset — say so everywhere

Main's plan-machine change (manaflow-ai#11756/manaflow-ai#11783) reduced cloudVMSizeAliases to
20g/20gb (or raw MB), but the error strings and usage lines still
advertised the retired 2g-32g ladder — ours worse, still carrying the
24g we added when that preset existed. vm run/route/agent unknown-size
errors, the vm new usage and unknown-flag text, docs/cli-contract.md's
vm new row (matching the freestyle-vm-primitives wording to keep that
merge clean), and every skill mention now name 20g (the 5 vCPU / 20 GB
/ 200 GB plan machine) or raw MB — matching parseCloudVMSize instead of
misleading an agent into a rejected --size 8g.

Also taken in this merge: main's manaflow-ai#11754 landed the Linux iOS-guard fix
this branch had been carrying, so those files resolve to main's
(77/77 local pass).

* skill: note headless staging flags coming in freestyle-vm-primitives

cmux176 implemented the two staging gaps flagged earlier — vm workspace
new --no-open and vm agent --remote-workspace — so the in-flight section
now names them and points §6b's workarounds at their replacement.

* fix: silence the guard-condition trailing-closure warning Xcode 26.3 added

The critical-pressure teardown hardening (via main) left two compactMap
trailing closures inside postAggregateMemoryPressureWarning's guard
condition; Xcode 26.3's compiler warns 'trailing closure in this context
is confusable with the body of the statement' on both (76:41, 77:41),
which fails the warning-budget lane with actual=2 budget=0 — on main's
own runs too (run 33716921978 shows the same +2). Parenthesized closure
arguments are the fix the diagnostic prescribes; no behavior change.

* fix: adapt the Base create launch to the 3-argument coordinator Launch

Two green PRs crossed on main: manaflow-ai#10773 added a 2-argument
MachineCreateCoordinator.start call in the Base sheet flow while manaflow-ai#11773
changed Launch to (arguments, progress, completion) for the pending
row's live output — main has not built the combination yet, and the
first tree containing both fails with 'contextual closure type expects
3 arguments'. The Base flow now takes the progress handler and threads
it through launchCloudVMBaseOpen into CloudVMActionLauncher's existing
onOutput, so Base creates stream output to the pending row exactly like
the New Machine sheet's flow in NewMachineSheetPresenter.

* test: make MachineCreateCoordinatorTests compile again after manaflow-ai#11773

Two fixes for main's own test file (byte-identical there, so main's
cmuxTests target does not compile either): #expect took the Bool? from
optional-chained isSuperseded (== true resolves it), and the new
MachinesPanelPendingCreateTests suite called Self.newMachineRequest for
a helper that lives on MachineCreateCoordinatorTests — qualifying the
type fixes the lookup and gives the trailing 'name: nil' its context.

(2026-09-06) every cmuxTests build on main fails, so no hosted unit test
run can pass. Austin authored this revert on another branch
(68e2dbc) but it never reached main. Re-land the feature with tests
