Cloud VPN: app-managed WireGuard tunnel via a NetworkExtension system extension, on-demand only - #11789
Merged
Conversation
Vendor the WireGuardKit Swift package from wireguard-apple 2fec12a6 (1.0.16-27, MIT) at vendor/WireGuardKit as a local SwiftPM package, with the upstream app target's wg-quick parser moved into the kit and made public, and one header fix for Xcode 26's strict module imports. The Go half is built by scripts/build-wireguard-go.sh: per-arch `go build -buildmode=c-archive`, lipo'd into BUILT_PRODUCTS_DIR where the kit's `link "wg-go"` expects it. Release/CI builds require Go; Debug builds without Go get a loud stub archive (marker symbol cmux_wireguard_go_bridge_is_stub) so dev builds stay green on machines without Go while release signing refuses to ship it. Upstream's Go runtime patch is not applied (iOS sleep timers; macOS re-handshakes via the adapter's path monitor). Third-party notices for WireGuardKit, wireguard-go, and golang.org/x are added; setup.sh reports whether Go is installed. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…d VPN Add the cmuxTunnelExtension target: a NetworkExtension packet-tunnel *system* extension (cmuxTunnel.systemextension, bundle id <app>.tunnel, embedded at Contents/Library/SystemExtensions) whose PacketTunnelProvider runs the completed wg-quick config through WireGuardKit. macOS only loads NE app extensions for Mac App Store apps; cmux ships via Developer ID, so the provider must be a system extension activated with OSSystemExtensionRequest. The config travels in the VPN configuration's providerConfiguration (root-only NE store) because system extensions run as root and cannot read the user's group container. App side, under Sources/Cloud/Tunnel: - CloudTunnelBackendSelector decides from the running binary (signed packet-tunnel-provider-systemextension + system-extension.install + a bundled extension) whether the app manages the tunnel; otherwise the wg-quick CLI path is unchanged. VMTunnelManager.networkExtensionAvailable delegates to it. - CloudTunnelCoordinator (actor) owns the lifecycle: off until the first private-network use, enroll + save VPN configuration + activate + start, bounded readiness budget for the caller, idle stop after 5 quiet minutes with no Cloud workspaces or links, pinned by `cmux vpn up`, stopped on sign-out, revoke, and quit. No NE on-demand rules: macOS never auto-connects it. - VMClient takes a CloudPrivateNetworkGate; every endpoint-minting call (attach, ssh, cmux-remote, session attach, open-port) starts the tunnel concurrently with the request, so the Machines panel, cmux-tui links, session restore, and every CLI verb share one trigger. - vm.tunnel_* socket verbs move to VMClientSocketCommands+Tunnel.swift and gain tunnel_up / tunnel_down / tunnel_wait plus backend and state fields; AppDelegate composes the coordinator. Behavior tests cover on-demand start, coalescing, wg-quick inertness, idle stop, consumer accounting, pinning, failure/retry, readiness budget, external disconnect, approval wait, sign-out/revoke, termination, and backend selection. New strings are localized (en/ja). Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
`cmux vpn up|down|status|revoke` pick their path from the socket response's `backend`. On app-managed builds they never touch sudo or wg-quick: `up` pins the tunnel through vm.tunnel_up and waits through the first-run System Settings approval with vm.tunnel_wait, `down` releases it, `status` shows the tunnel state, and `revoke` lets the app stop and delete the VPN configuration. wg-quick builds behave exactly as before. Help text explains that the tunnel normally needs no verb at all. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…he profile
cmux.release.entitlements and cmux.nightly.entitlements declare the
desired state: com.apple.developer.networking.networkextension =
[packet-tunnel-provider-systemextension], system-extension.install, and
the team App Group. macOS refuses to launch a Developer ID app whose
signature claims a restricted entitlement its embedded profile does not
grant, so scripts/reconcile-entitlements-with-profile.py computes the
effective entitlements per signing run and sign-cmux-bundle.sh drops the
tunnel keys and removes the extension when the profile lacks the
capability. The next release therefore still launches and keeps the
wg-quick path until the Apple portal work is done. With the capability
granted, the script requires the extension's own embedded profile,
rejects a stub WireGuard bridge, signs the extension with its
release/nightly entitlements, and verifies both sides agree.
Workflows install Go before Release xcodebuilds, embed the optional
APPLE_{RELEASE,NIGHTLY}_TUNNEL_PROVISIONING_PROFILE_BASE64 secrets into
the extension, rename the nightly extension to
com.cmuxterm.app.nightly.tunnel, and check the extension binary is
universal and not the stub. strip-release-bundle.sh strips it. Each new
script has behavior tests under tests/.

The vendored go.mod/go.sum are the pinned module set; a build must fail rather than rewrite them, so the c-archive build runs with GOFLAGS=-mod=readonly. Verified the pinned set still builds universal with Go 1.26. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Resolves the tunnel conflicts semantically: main's per-environment interface names, applied-config staleness tracking (vm.tunnel_applied, stale/config_digest fields) and the sidebar's private-route blocker stay, and the app-managed backend layers on top — its liveness comes from NEVPNStatus rather than the wg-quick name file, staleness does not apply to it, and the sidebar blocker reads the coordinator's state on that backend. The nightly universal-architecture check was removed upstream (per-architecture DMGs), so the tunnel extension arch check goes with it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Inline comments:
In `@cmux.xcodeproj/project.pbxproj`:
- Around line 13710-13713: Commit the root Xcode SwiftPM lockfile at the
workspace shared-data location, updating Package.resolved to reflect the local
WireGuardKit reference introduced by XCLocalSwiftPackageReference.
In `@Resources/Info.plist`:
- Around line 99-100: Add NSSystemExtensionUsageDescription to
TunnelExtension/Info.plist with the extension’s usage description, and add the
corresponding localized catalog entry. Ensure this metadata is present in the
plist used by the cmuxTunnelExtension target for both Debug and Release.
In `@Resources/Localizable.xcstrings`:
- Line 273262: Update the localized fallback text used by
CloudTunnelError.backendUnavailable through userMessage(for:) in both locales,
keeping “cmux vpn up” while removing the user-facing “wg-quick” reference.
In `@Sources/Cloud/CloudMachineLinkManager.swift`:
- Line 160: Update CloudMachineLinkManager.connected(machineID:) so pending
links are counted as tunnel consumers, not only links where isConnected is true;
include connecting machine IDs in the consumer count or reuse an equivalent
pending-connection lease while CloudMachineLink.connect is incomplete.
In `@Sources/Cloud/Tunnel/CloudTunnelCoordinator.swift`:
- Line 92: Update the error logging sites in
Sources/Cloud/Tunnel/CloudTunnelCoordinator.swift at lines 92-92, 239-239, and
272-272 to mark dynamic error values as privacy .private while keeping fixed
event text public. Apply the change to the relevant logger calls without
altering their messages or control flow.
- Line 407: Update the error-description handling in CloudTunnelCoordinator so
unexpected NSError values are mapped to fixed localized product text rather than
returning nsError.localizedDescription. Apply this consistently to failure-state
messages, thrown errors, and .public log entries, while retaining raw
diagnostics only in non-user-facing internal contexts.
- Around line 203-204: Update the start flow around performStart and startTask
to track the active tearDown shutdown operation, and make new starts await its
completion before invoking controller.install or controller.start. Preserve
generation checks for state updates while ensuring ensureUp cannot begin a
tunnel until controller.stop and the disconnected wait have finished.
In `@Sources/Cloud/Tunnel/NetworkExtensionTunnelController.swift`:
- Around line 44-47: Update currentStatus() to load the authoritative saved
manager from preferences when the cached manager is nil, then derive
CloudTunnelLinkStatus from that manager’s connection status. If reliable state
cannot be loaded, return the existing explicit unknown state rather than
guessing .disconnected; preserve the cached-manager path.
- Around line 34-36: Update the notification loop around statusUpdates to yield
only when the notification’s NEVPNConnection is identical to this controller’s
manager?.connection; ignore notifications from other connection instances while
preserving the existing CloudTunnelLinkStatus conversion for the owning
connection.
In `@Sources/Cloud/Tunnel/SystemExtensionActivator.swift`:
- Around line 96-110: Add localized translations for
cloudTunnel.error.activationCanceled, cloudTunnel.error.activationNotAllowed,
and cloudTunnel.error.activationFailed in Resources/Localizable.xcstrings for
all 20 supported locales, preserving the existing default messages and format
placeholder for activationFailed.
In `@Sources/Cloud/VMClientSocketCommands`+Tunnel.swift:
- Around line 110-120: Track active tunnel ownership separately from the
selected backend: in VMClientSocketCommands+Tunnel.swift lines 110-120, expose
whether the active interface is owned by NetworkExtension or legacy wg-quick; in
CLI/CMUXCLI+VPN.swift lines 115-118 and 261-263, use that ownership state to run
wg-quick teardown whenever a legacy interface is active and NetworkExtension
does not own it.
In `@vendor/WireGuardKit/Sources/WireGuardKit/Array`+ConcurrentMap.swift:
- Around line 21-24: Update the concurrentMap implementation around the execute
closure and DispatchQueue.concurrentPerform so the queue contract is correct:
either remove the queue parameter and its synchronization wrapper, or redesign
execution to honor the supplied queue without deadlocking when called from that
queue. Ensure the documented serial-versus-concurrent behavior is preserved.
In `@vendor/WireGuardKit/Sources/WireGuardKit/PrivateKey.swift`:
- Line 45: Implement hash(into:) in BaseKey so its Hashable conformance
compiles, hashing rawValue consistently with the class’s equality behavior.
In `@vendor/WireGuardKit/Sources/WireGuardKitGo/api-apple.go`:
- Line 70: Update the runtime.Stack call in the SIGUSR2 stack-trace handling to
use a buffer one byte shorter than buf, then preserve the existing buf[n]
terminator write so n can never equal the buffer length.

Debug CI lanes (tests-build-and-lag, app-host unit tests) run on macOS runners without Go; a Debug build cannot load the extension anyway, so the stub engine is the right outcome there. Release builds still fail closed without Go, and the release workflows install it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…rseded cleanup The system extension outlives the app. After a crash or kill the VPN can already be connected when the next app instance first uses Cloud; startVPNTunnel on a live session posts no status change, so the start waited out the connect timeout, reported a failure, and stopped a working tunnel. The coordinator now reads the controller's current status after saving the configuration and adopts a connected link (or waits on a connecting one) instead of restarting it. A start superseded by a stop (an approval wait is not cancellable) that later fails no longer runs the cleanup stop, which could disconnect a newer start's tunnel; the cleanup is generation-guarded like setState. Tests cover both: adoption skips start(), and a superseded start's late failure leaves the newer tunnel and its call log untouched. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Split the value types and the activation delegate out of the files that declared them alongside a protocol or enum, per the cmux file-organization policy: CloudPrivateNetworkUse, CloudPrivateNetworkNoopGate, CloudTunnelFallbackReason, CloudTunnelAppConsumers, CloudTunnelProviderConfiguration, CloudTunnelEnrollment, CloudTunnelProviderMessage (shared with the extension target), CloudTunnelStatus, SystemExtensionActivationDelegate. Nested types stay nested. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
#11773 gave MachineCreateCoordinator.Launch a progress callback and updated NewMachineSheetPresenter but not the Base-open launcher in AppDelegate, so main no longer compiles the app target (every app-host CI lane is red). Base open renders its output in the workspace's loading pane, so the progress stream has no reader here and is ignored. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

lifecycle state use the same authoritative typed tunnel state.

…ed start The system extension outlives the app, so a tunnel the previous instance left connected must still answer to quit, sign-out, and `cmux vpn down` before this instance has used Cloud. The NetworkExtension controller now reads the app's existing VPN configuration at launch (a passive preferences load, no prompt) and on demand, and tearDown stops a link the controller reports connected even when the coordinator's own state is off. After a failed start, Cloud uses no longer re-run enrollment, extension activation, and the configuration save on every dial: a 30 s failure backoff (clock-driven, cancellable) suppresses retries; `cmux vpn up` always retries. Tests cover the inherited-tunnel stop, the backoff, and the explicit bypass; the test doubles move to CloudTunnelTestFakes.swift to keep the suite under 500 lines.

In `@cmuxTests/CloudTunnelCoordinatorTests.swift`:
- Around line 230-232: Replace the unbounded isInFailureBackoff polling loop in
the coordinator test with the project’s deadline-bounded predicate-wait utility,
preserving the existing condition and clock advancement while ensuring a stuck
backoff state fails locally within a defined timeout.
In `@Sources/Cloud/Tunnel/CloudTunnelCoordinator.swift`:
- Line 232: Update the CloudTunnelCoordinator flow around linkStatus and
waitForLink(.connected) so sawConnecting is initialized from the existing
linkStatus before status updates are consumed, including .connecting and
.reasserting states. Add coverage for an inherited .connecting tunnel
transitioning directly to .disconnected and verify it fails immediately rather
than waiting for connectTimeout.
In `@Sources/Cloud/Tunnel/NetworkExtensionTunnelController.swift`:
- Around line 28-30: Update the launch-time initialLoad task to load
NETunnelProviderManager directly through a separate helper instead of calling
loadExistingManagerIfNeeded(), preventing the task from awaiting its own
initialLoad.value. Retain loadExistingManagerIfNeeded() for callers that must
await the existing task, and ensure currentStatus(), stop(), and remove()
observe the manager loaded during launch without racing or blocking.
In `@Sources/Cloud/Tunnel/SystemExtensionActivationDelegate.swift`:
- Around line 55-59: Update userFacingError(for:) in
SystemExtensionActivationDelegate to return a generic localized
CloudTunnelError.startFailed error for the fallback path when the input is not a
recognized OSSystemExtensionError, so CloudTunnelCoordinator.userMessage(for:)
cannot expose raw activation details.
- Line 39: Update the activation-result handling in
SystemExtensionActivationDelegate so only .completed returns success, while
.willCompleteAfterReboot remains pending and any unknown result returns a
sanitized CloudTunnelError.startFailed through the completion handler.

Swift rejects 'await' in an autoclosure that does not support concurrency; the fallback read of the coordinator's state is now a plain statement. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
… broadcast subscribers eagerly Release signing and the release workflow now run scripts/verify-tunnel-extension-engine.sh, which requires the Go __go_buildinfo Mach-O section and an exported wgTurnOn. Both survive strip -S -x and dead-code stripping, unlike the stub's marker symbol (an unreferenced global a Release link may drop), so a stub can never pass as the real engine. The test builds the stub and, when Go is installed, the real archive, and checks both verdicts. CloudTunnelBroadcast drops subscribers as soon as their stream terminates (onTermination records the id behind a lock; subscribe and yield prune), so polling clients that subscribe and leave between state changes no longer accumulate. Covered by CloudTunnelBroadcastTests. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

…k drops, redact runtime keys, enroll once - A Cloud use that arrives while a stop is draining (idle timer, vpn down, sign-out) now queues behind the tracked stop task instead of racing NetworkExtension with a start and failing into the backoff. - waitForLink seeds its connecting flag from the current link status, so an adopted connecting/reasserting link that drops fails fast instead of waiting out the connect timeout. - The provider strips private_key/preshared_key lines from the runtime configuration it returns to the app (CloudTunnelRuntimeConfigurationRedactor, shared with the extension target). - cmux vpn up on the app-managed backend reads vm.tunnel_status first and lets the app's start enroll once, instead of enrolling via vm.tunnel_config and again inside the start. - CloudTunnelBroadcast is lock-free again: termination is reported to the owning actor, which prunes under its own isolation. - The deadline helper and error mapping move to CloudTunnelCoordinator+Deadline to keep the coordinator well under the file budget. Tests: mid-stop use queues behind the stop; adopted connecting link fails fast; broadcast termination reporting; redactor. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

The Cloud VPN branch (#11789, commit c9272d3) removed the cmux-tui fallback helpers from CLI/CMUXCLI+VMTui.swift, including this constant, because every Cloud route now goes through the WireGuard hub. Five hours later main gained a new use of the same constant in shouldFallbackFromForcedSSH (c8098d7). The branch's later merges of main combined both sides without a textual conflict, and the squash merge landed the dangling reference on main. PR CI never compiled Swift for #11789: web-typecheck failed, so linux-preflight failed and every macOS job was skipped, while the no-op "CI status fallback" workflow satisfied the required ci-status check and auto-merge went ahead. Restore the constant in CLI/CMUXCLI+VMTui.swift. The control plane still answers 409 vm_attach_transport_unsupported (web/services/vms/routeHelpers.ts), and VMSSHCommandTests.testVMSSHAliasUsesCmuxRemoteWhenProviderSSHIsUnmanaged covers the forced-SSH fallback that reads it.

Redo the merge from git's automatic result: main's structure and logic stay, and the branch's intended changes are applied on top. Ports are no longer probed through provider exec; the cached scan is used until the cmux-tui link is up, then `ports(link:socketPath:)` refreshes `scannedPorts`/`currentPorts` for `publish`. The desktop row carries its private noVNC URL everywhere it is created (`desktopDisplayResource()`), the provider preview-endpoint machinery stays removed, and the old `VMTunnelManager.privateRouteBlocker()` text stays removed because that API no longer exists.

Build error on main after the constant fix: Sources/Cloud/CloudMachineLink.swift:166: value of type 'CloudMachineLink' has no member 'eventsRecoveryClock' Keep the branch's additions (hub lease release, `eventsProcessExit` with `terminateAndWait` before a replacement reader, async `disconnect`/`linkProcessDidExit`) on top of main's logic. `startEventsSubscription(socketPath:cursor:)` is now async because it waits for the previous events child; `restartEventsSubscription`, `resumeEventsSubscription`, and `recoverEventsSubscription` propagate that. Callers already await them (actor).

Put both back so the chain works end to end again. Also restore the `vm terminal rename` row in docs/cli-contract.md, which the merge removed from the CLI contract table.

…App ID
The first release dry run that could start after the permission fix
(run 34222835589) failed 30 minutes in, at "Verify binary architectures":
error: system extension identifier is 'com.cmuxterm.app.tunnel',
expected '7WLXT3NR37.com.cmuxterm.app.tunnel'
#11789 passed the team-prefixed App ID to
scripts/normalize-system-extension-bundle.sh and looked for the tunnel
binary under 7WLXT3NR37.com.cmuxterm.app.tunnel.systemextension. The
Release build's PRODUCT_BUNDLE_IDENTIFIER for the extension is
com.cmuxterm.app.tunnel; only NEMachServiceName
($(CMUX_TEAM_ID_PREFIX)$(PRODUCT_BUNDLE_IDENTIFIER)) and the provisioning
profile's com.apple.application-identifier carry the team prefix, and the
app activates whatever CFBundleIdentifier the bundled extension declares.
nightly.yml already does it this way and ships
com.cmuxterm.app.nightly.tunnel.systemextension with a profile for
7WLXT3NR37.com.cmuxterm.app.nightly.tunnel (run 34220568401). The mistake
was invisible until now because release.yml could not start at all.
Use the bundle identifier for the normalize call and the directory the
verify step inspects; keep the App ID for the profile check.
tests/test_ci_release_tunnel_identifiers.sh derives all three from
cmux.xcodeproj/project.pbxproj (fails on main's release.yml, passes here)
and runs in workflow-guard-tests.

…issions guard, screenshot decoupling, notarization hardening) (#12157) * ci: guard reusable-workflow permission grants (red on main's shape) GitHub validates a reusable workflow's permissions against the calling job when it parses the caller. A callee that requests a scope the caller does not grant fails the whole caller run at startup, before any job runs. That is what blocks the stable release today: release.yml calls ios-screenshots.yml, which requests `actions: write` while release.yml grants none (#12149). Add scripts/ci/check_reusable_workflow_permissions.py (python3 stdlib only) that walks every local `uses: ./.github/workflows/*.yml` call, computes the calling job's grant (job block, else workflow block, else the repository default) and the callee's request (max over its workflow block and every job block, gated jobs included, mirroring 4b9720d), follows nested calls with the intermediate grant, and fails on any scope that asks for more. tests/test_ci_reusable_workflow_permissions.py covers the rule on fixture trees (the exact #12149 shape, shorthands, job-level overrides, repository defaults, nesting, missing callees) and then runs the checker on the real tree, which fails until the next commit fixes the workflows. Wired into the workflow-guard-tests job in ci.yml. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * ci: stop ios-screenshots.yml requesting actions: write (fixes release startup) The screenshot workflow declared `actions: write` since #6697, but no step ever used it: checkout runs with persist-credentials disabled, the two artifact uploads use the runner's artifact token, the capture is a DEBUG simulator build, and the App Store Connect upload path authenticates with an API key. When #11342 made release.yml call this workflow, GitHub compared the callee's block with the caller's grant (contents/attestations/id-token only) and refused the release workflow at parse time: startup_failure, no job run, for tag pushes and dispatches alike (#12149). Reduce the callee to `contents: read`, the minimum its steps use. Widening release.yml instead would have handed a UI-test job the ability to cancel or dispatch runs for no benefit. The guard added in the previous commit now passes on the tree. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: do not gate build-sign-notarize on iOS screenshot capture #11342 made build-sign-notarize need generate-ios-screenshots ("gates build-sign-notarize on screenshot success"). The DMG never consumes those artifacts: nothing in build-sign-notarize downloads them, and the App Store tooling (ios/scripts/appstore-shots.sh capture) dispatches its own ios-screenshots.yml run rather than reading a release run. What the gate did do was make every stable macOS release wait for, and fail with, a 300-minute simulator capture across nine locales on shared macOS runners, a lane that had "not compiled on main for days" before #11342 healed it. Keep the capture in release.yml as a sibling job, so every tag still gets screenshots at the exact release ref and a failed capture still turns the run red, but drop it from build-sign-notarize.needs. Trade-off: a green macOS release no longer implies the screenshot capture succeeded; the run conclusion still does. tests/test_ci_release_ios_screenshots_decoupled.sh pins the policy (fails on main's needs list, passes here) and runs in workflow-guard-tests. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: give the screenshot capture job only contents: read and no secrets The screenshot job runs a DEBUG simulator UI test after `brew install` of fastlane and imagemagick. Capture-only needs to read the repository and nothing else: checkout runs with persist-credentials disabled, artifact uploads use the runner's artifact token, and the App Store Connect upload path in ios-screenshots.yml is gated to workflow_dispatch from main, so it is unreachable from a release run whatever `upload` says. Set job-level `permissions: contents: read` on the calling job (the pattern the cmux-tui callers already use) instead of passing the workflow's contents/attestations/id-token write grant through, and drop `secrets: inherit`, which handed every repository secret (Developer ID certificate and password, notarization credentials, Sparkle private key, R2 keys, Sentry token, ASC key) to that job for no benefit. Trade-off: if the release lane ever wants the ASC upload, it must add `secrets: inherit` back together with `upload: true` and relax the callee's dispatch-only guard. That should be a deliberate change. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: let the Sparkle monotonic guard warn on non-tag dry runs release.yml runs tests/test_ci_sparkle_build_monotonic.sh at the top of build-sign-notarize. On plain main it fails (CURRENT_PROJECT_VERSION 102 equals the published 0.64.22 build), which is correct for a tag push about to publish but wrong for the workflow's built-in dry run: a non-tag workflow_dispatch publishes nothing and, by design, runs from a branch that has not been bumped yet. The dry run was therefore impossible without a throwaway bump commit. Chosen fix: a CMUX_SPARKLE_MONOTONIC_MODE switch on the guard, `enforce` by default (tag pushes, scripts/release-pretag-guard.sh) and `warn` when release.yml runs from anything but refs/tags/*. Rejected alternative: running the dry run from a throwaway branch with a temporary bump, which would validate a commit that never merges and leave the pipeline un-dry-runnable for everyone else. tests/test_sparkle_build_monotonic_modes.sh drives the guard against fixture project files and a local appcast (stale fails in enforce and by default, warns in warn mode, bumped passes in both, unreachable appcast soft-passes, unknown mode fails) and pins the ref-based selection in release.yml. Wired into workflow-guard-tests.

The budget was 20 x 15s. Nightly run 34208928547 (2026-09-08) exhausted it: Accepted at 09:51:28, still "Unnotarized Developer ID" at 09:56:18, exit 3, whole universal lane failed, while the arm64 and x86_64 lanes passed in the same window. Raise the default to 80 x 15s (twenty minutes) and announce the budget on the first rejection so a log reader can tell propagation from a hang. Trade-off: a genuinely rejected helper now takes up to twenty minutes to fail instead of five, which only delays an already-lost release; a short budget failed good releases, each costing a full rebuild and a human retry. Both knobs remain env-configurable (CMUX_GATEKEEPER_ASSESS_ATTEMPTS/_DELAY_SECONDS). nightly's signing job has an 80-minute timeout with a 7-10 minute typical duration, so the budget fits there; release.yml's timeout is raised in the next commit. tests/test_notarize_computer_use_helper.sh now pins the defaults (at least 1200s, polled at least every 30s, env-configurable literals) and the budget announcement, alongside the existing override and give-up coverage.

Since then the job gained the Cloud tunnel system extension and its Go engine build (#11789), the universal diff sidecar and cmux-tui client install (#12006), two extra smoke launches, and a Gatekeeper propagation wait that can now run twenty minutes on its own. A 60-minute ceiling leaves no room for a slow notarytool day, and a timeout mid-notarization wastes the whole build. 90 minutes covers the measured baseline plus the known variable waits with headroom while still bounding a hung job on a shared self-hosted runner. To be re-checked against the dry-run duration for this branch: the timeout must stay at least 25 percent above it.

The Release build's PRODUCT_BUNDLE_IDENTIFIER for the extension is com.cmuxterm.app.tunnel; only NEMachServiceName ($(CMUX_TEAM_ID_PREFIX)$(PRODUCT_BUNDLE_IDENTIFIER)) and the provisioning profile's com.apple.application-identifier carry the team prefix, and the app activates whatever CFBundleIdentifier the bundled extension declares. nightly.yml already does it this way and ships com.cmuxterm.app.nightly.tunnel.systemextension with a profile for 7WLXT3NR37.com.cmuxterm.app.nightly.tunnel (run 34220568401). The mistake was invisible until now because release.yml could not start at all. Use the bundle identifier for the normalize call and the directory the verify step inspects; keep the App ID for the profile check. tests/test_ci_release_tunnel_identifiers.sh derives all three from cmux.xcodeproj/project.pbxproj (fails on main's release.yml, passes here) and runs in workflow-guard-tests.

Fix both at the root rather than refreshing the budget: - swift-package-tests: FakeTerminalEngine.swift gained a `UUID` parameter in #10564 but imports only GhosttyKit. Add `import Foundation`. - tests-build-and-lag (scripts/swift_warning_budget.py, actual > budget): * AppDelegate+PaneMemoryGuardrail.swift: parenthesize the two `compactMap` closures inside the `guard` condition ("trailing closure in this context is confusable with the body of the statement"). * SessionIndexTableController.swift: the bounds-change observer block is typed @sendable in the current SDK, so referencing `isApplyingRows` and `reconcilePresentation(in:)` warned. The block is delivered on `queue: .main`, so run it under `MainActor.assumeIsolated`, the same pattern SidebarWorkspaceRowCellView uses; no async hop, same timing. * CmuxTuiSnapshotParser.swift: `switch resourceID.kind` already covers every SurfaceResourceKind case (terminal, display, browser), so the `default: continue` could never run. Remove it; a new case now fails to compile here instead of being silently skipped. * SurfaceCatalogModel.swift: `if let rowID,` rebound a value the body never read; test `rowID != nil` instead. * TerminalController.swift: `payload` in the `.delivered` branch is never mutated; make it `let`. Every change is behavior-preserving. Verified with `swiftc -parse` on each file locally (no app build on the shared machine); the routed CI lane proves the build and the budget.

This is the output of scripts/normalize-pbxproj.py: three lines reordered, no identifier or setting changed.

The job log shows why: ./scripts/sparkle_generate_appcast.sh: line 93: delta_args[@]: unbound variable A tag push would have published a GitHub Release without appcast.xml, so no Sparkle client would ever be offered the update, and the R2 stable appcast upload would then fail after the release already existed. tests/test_sparkle_generate_appcast_no_deltas.sh runs the real script with fake git/xcodebuild/generate_appcast/sign_update tools under every bash on the machine (/bin/bash 3.2 on macOS reproduces the bug; bash 5 never did) and requires a signed appcast at the requested output path with no delta arguments when there are no previous archives, and with --maximum-deltas when there are. It also requires release.yml to verify the feed after generation instead of trusting the exit status. Fails on main's script and workflow; the next commit fixes both. Wired into workflow-guard-tests. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: generate the appcast when there are no previous archives (bash 3.2) #11788 added `delta_args=()` and passed "${delta_args[@]}" to generate_appcast. In bash 4.4+ an empty array expands to nothing; in bash 3.2 (macOS /bin/bash, which `#!/usr/bin/env bash` resolves to on the release runner) it is an "unbound variable" error under `set -u`. Worse, with the script's EXIT trap bash 3.2 then exits 0, so the step passed and no appcast was written. Nightly always has previous archives (delta_args non-empty) and was never affected; the stable release lane never has them and has been broken since 2026-09-03, unnoticed because release.yml could not start at all (#12149). Expand the array as ${delta_args[@]+"${delta_args[@]}"}, which is empty when the array is empty in every bash. In release.yml, verify after generation that appcast.xml exists, carries sparkle:edSignature and references cmux-macos.dmg before anything uploads it: the exit status alone is not a reliable signal on bash 3.2.

A missing signal must fail closed when the run is about to publish. enforce mode now fails with an explanation when the published build is unknown; warn mode (non-tag dry runs) keeps the soft pass because it publishes nothing. curl retries transient failures (3 x 2s by default, overridable so the tests exercise the unreachable path without waiting). tests/test_sparkle_build_monotonic_modes.sh covers enforce, default and warn against an unreachable appcast.

It updated the Python hook tests to the new wire contract but not ClaudeHookLifecycleCleanupTests, whose two moved-pane tests still expected the removed command. They fail on main in the strict app-host agent-notification step (shard 6), unnoticed because #11976's PR CI never routed the macOS lane. Assert the new contract instead: the journal event for the hook names the re-homed workspace and the live pane (via the existing AgentJournalAppendCapture parser), and nothing still wipes the whole destination workspace. SessionEnd keeps sending the v1 command, so its tests are unchanged. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * ci: make app-host hangs fail in minutes instead of the 75-minute job timeout Every macOS lane run since 2026-09-03 has ended with app-host shards "cancelled" at the 75-minute job timeout. Today's logs (run 34236235360, shards 1/2/4, both attempts) show the mechanism, and it is two plumbing defects rather than the tests: 1. scripts/ci/xcodebuild_noninteractive.py resets its 300s idle deadline on every output chunk. Since #11755 (merged 2026-09-03T02:09Z, after the last green lane at 2026-09-02T09:21Z) the app host logs every Cloud API poll, `[CloudVM] GET /api/vm not_signed_in`, every 45 seconds. A test host hung inside a WebKit page load (WebContent XPC: "Could not signal service ... 113") therefore never looks idle, so the wrapper's kill and retry path, which handled the same WebKit failure on the 09-02 green run, never fires. 2. The tolerant batch watchdog in ci.yml (1800s) killed only the console-session launcher and left the lock wrapper, xcodebuild and the app host alive; the app host kept the `| tee` pipe open, so the step sat idle from "timeout after 1800s; terminating" until the job timeout. Fixes: - CMUX_XCODEBUILD_NONINTERACTIVE_IDLE_IGNORE_RE: output lines matching it do not count as progress. run-app-host-xcodebuild.sh defaults it to the Cloud poll line (an empty value restores counting everything; an invalid regex fails closed with exit 2). Real output still resets the clock, so a slow but progressing batch is unaffected. - The ci.yml batch runner writes xcodebuild output to the capture file and streams it with a detached tail, kills the whole process tree (pgrep -P recursion, TERM then KILL) when the batch budget expires, and reads both the streamed and per-batch captures for the SwiftPM retry heuristic. Behavior tests: tests/test_ci_xcodebuild_noninteractive_helper.py drives a child that prints only the keepalive every 50ms (finishes without the pattern, idles out at 0.3s with it, invalid pattern exits 2); tests/test_ci_change_areas.py runs the real step script against a runner that hangs and leaves a grandchild holding stdout, and requires exit 124 within seconds with the grandchild dead. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * ci: keep the canonical OUTPUT capture line the SPM-retry guard pins tests/test_ci_unit_test_spm_retry.sh requires `OUTPUT=$(cat "$TEST_OUTPUT")` verbatim in the app-host step; the previous commit folded the per-batch capture files into that line and turned workflow-guard-tests red. Keep the pinned line and append the per-batch captures on the next line instead. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * ci: keep a watchdog-killed app-host batch terminal; drop the wall-clock assert CodeRabbit on #12157: the expected-failure normalization in run_unit_test_batch greps the capture for the last "Executed ... failures" summary and returns success on "(0 unexpected)". After the watchdog kills a batch (status 124) the capture can still hold an earlier attempt's summary (run-app-host-xcodebuild.sh retries into the same file), so a terminated batch could be reported as passed. Treat 124 as terminal before the normalization. The hung-runner behavior test now prints a decoy "(0 unexpected)" summary before hanging and requires the step to stay at 124 without the "All failures ... are expected" message. Also drop the `elapsed < 60` assertion from that test: the harness's 120s subprocess timeout already bounds a runaway step, and a hard wall-clock ceiling only adds scheduler-delay flakes. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * chore: normalize project file after main merge * test: remove timing dependency from terminal lane test * ci: accept completed app-host summaries after launcher timeout * test: make idle watchdog coverage scheduler tolerant * ci: require Swift Testing completion before accepting launcher timeout * ci: fail fast on known broad app-host hangs * test: allowlist virtual retry delay fixtures * ci: preserve app-host lock queue headroom * ci: restore terminal creation CLI regression coverage * ci: retain release guard coverage after main merge * ci: remove obsolete app-host idle override * cmuxTests: run the Coderouter no-socket tests without an unwaited expectation `runCoderouterCLI(waitForSocket: false)` still asked `startMockServer` for a case-bound `expectation(description: "cli mock socket handled")` and then never waited on it. The shared accept loop fulfills that expectation when the listener closes at the end of the helper, so XCTest ended `testCoderouterUnknownVerbStillPassesThroughToTheInstalledCLI` and `testCoderouterClaudeAddOAuthTokenRejectsAPIKeyShapeBeforeTheSocket` with "Failed due to unwaited expectation", which it counts as an *unexpected* failure. Since #12207 the app-host batch classifier fails a batch on any unexpected failure, so this one test turned shard 5 (and the sibling test shard 6) red on main and on every PR: run 34401456032, main run 34342638735 attempts 1 and 2. Serve those two tests from the detached mock server instead, which owns no expectation, and keep the waited path for every other Coderouter test. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * ci: rerun a remote tmux mirror suite once after an app-host crash The non-tolerant "Run remote tmux mirror detach and placement regressions" gate on shard 6 fails whenever the app host crashes mid-suite, which #9348 documents as nondeterministic: the crash point moves between tests and the relaunched host passes the rest (run 34401456032 crashed in dedicatedWindowSocketDefaultsToFocusNeutral; the previous run and both main attempts passed the same step). Capture each suite's output and rerun the suite exactly once, only when xcodebuild printed "Restarting after unexpected exit, crash, or test timeout". An assertion failure never earns a rerun and a second crash still fails the shard, so the gate keeps rejecting real regressions. tests/test_ci_change_areas.py drives the real step script against a fake console runner: crash-then-pass is green with three invocations, an assertion failure exits 65 after one invocation, and two crashes exit 65 after two. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(iroh): promote the replacement connection deterministically usableConnectionRetiresOlderConnectionsFromSameEndpointIdentity keyed the markUsable call off `recorder.recordedCount() == 2`, which both handlers evaluate concurrently. When the first connection's handler reached that check after the replacement had already recorded, it promoted `first` instead, superseded the freshly admitted replacement, and the replacement's own markUsable returned false: "Expectation failed: await admission.markUsable()" at CmxIrohEndpointServerTests.swift:353 in CI run 34414741413 (swift-package-tests), while the previous run passed the same code. Admit before recording so the test's `recorder.next()` proves `first` is active before `replacement` is enqueued, and promote only the replacement by identity. The suite passes three consecutive local runs. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * cmuxTests: serialize the stdin pump suite and bound its blocking waits Shard 3 of CI run 34414741413 hung three times at the app-host wrapper's 300s idle timeout in the same batch. The hang sample shows SSHPTYAttachReconnectInputFilterTests.stdinPumpFiltersReadyInputBeforeStopSignal parked in stopFiltering() -> read() on the stop-acknowledgement pipe with every other visible cooperative-pool thread also inside a test body's synchronous wait. The pump under test is a detached task that needs one of those same threads, and the five pump tests each hold a thread for the ~13s reconnect probe deadline while running concurrently, so the suite can leave no thread for any pump (the family issue #12180 tracks). Run the suite serialized so at most one test parks a thread at a time, and bound every wait: stopFiltering now takes a 30s acknowledgement timeout and must succeed, and the EOF/exact reads poll with the same deadline. A pump that never gets scheduled now fails its test inside the batch instead of parking the shard until the idle timeout retries are exhausted. The two assertions in this suite that already fail on main (readUntilEOF == forwardedInput in stdinPumpFiltersReadyInputBeforeStopSignal and stdinPumpKeepsFilteringLateProbeRepliesAfterInitialDrain) are unchanged; the batch classifier tolerates them today.

… extension, on-demand only (manaflow-ai#11789) * Cloud tunnel: vendor WireGuardKit and build the wireguard-go bridge Vendor the WireGuardKit Swift package from wireguard-apple 2fec12a6 (1.0.16-27, MIT) at vendor/WireGuardKit as a local SwiftPM package, with the upstream app target's wg-quick parser moved into the kit and made public, and one header fix for Xcode 26's strict module imports. The Go half is built by scripts/build-wireguard-go.sh: per-arch `go build -buildmode=c-archive`, lipo'd into BUILT_PRODUCTS_DIR where the kit's `link "wg-go"` expects it. Release/CI builds require Go; Debug builds without Go get a loud stub archive (marker symbol cmux_wireguard_go_bridge_is_stub) so dev builds stay green on machines without Go while release signing refuses to ship it. Upstream's Go runtime patch is not applied (iOS sleep timers; macOS re-handshakes via the adapter's path monitor). Third-party notices for WireGuardKit, wireguard-go, and golang.org/x are added; setup.sh reports whether Go is installed. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * Cloud tunnel: packet-tunnel system extension and on-demand app-managed VPN Add the cmuxTunnelExtension target: a NetworkExtension packet-tunnel *system* extension (cmuxTunnel.systemextension, bundle id <app>.tunnel, embedded at Contents/Library/SystemExtensions) whose PacketTunnelProvider runs the completed wg-quick config through WireGuardKit. macOS only loads NE app extensions for Mac App Store apps; cmux ships via Developer ID, so the provider must be a system extension activated with OSSystemExtensionRequest. The config travels in the VPN configuration's providerConfiguration (root-only NE store) because system extensions run as root and cannot read the user's group container. App side, under Sources/Cloud/Tunnel: - CloudTunnelBackendSelector decides from the running binary (signed packet-tunnel-provider-systemextension + system-extension.install + a bundled extension) whether the app manages the tunnel; otherwise the wg-quick CLI path is unchanged. VMTunnelManager.networkExtensionAvailable delegates to it. - CloudTunnelCoordinator (actor) owns the lifecycle: off until the first private-network use, enroll + save VPN configuration + activate + start, bounded readiness budget for the caller, idle stop after 5 quiet minutes with no Cloud workspaces or links, pinned by `cmux vpn up`, stopped on sign-out, revoke, and quit. No NE on-demand rules: macOS never auto-connects it. - VMClient takes a CloudPrivateNetworkGate; every endpoint-minting call (attach, ssh, cmux-remote, session attach, open-port) starts the tunnel concurrently with the request, so the Machines panel, cmux-tui links, session restore, and every CLI verb share one trigger. - vm.tunnel_* socket verbs move to VMClientSocketCommands+Tunnel.swift and gain tunnel_up / tunnel_down / tunnel_wait plus backend and state fields; AppDelegate composes the coordinator. Behavior tests cover on-demand start, coalescing, wg-quick inertness, idle stop, consumer accounting, pinning, failure/retry, readiness budget, external disconnect, approval wait, sign-out/revoke, termination, and backend selection. New strings are localized (en/ja). Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * cmux vpn: app-managed shims when the app owns the tunnel `cmux vpn up|down|status|revoke` pick their path from the socket response's `backend`. On app-managed builds they never touch sudo or wg-quick: `up` pins the tunnel through vm.tunnel_up and waits through the first-run System Settings approval with vm.tunnel_wait, `down` releases it, `status` shows the tunnel state, and `revoke` lets the app stop and delete the VPN configuration. wg-quick builds behave exactly as before. Help text explains that the tunnel normally needs no verb at all. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * Release: declare the Cloud tunnel entitlements, reconcile them with the profile cmux.release.entitlements and cmux.nightly.entitlements declare the desired state: com.apple.developer.networking.networkextension = [packet-tunnel-provider-systemextension], system-extension.install, and the team App Group. macOS refuses to launch a Developer ID app whose signature claims a restricted entitlement its embedded profile does not grant, so scripts/reconcile-entitlements-with-profile.py computes the effective entitlements per signing run and sign-cmux-bundle.sh drops the tunnel keys and removes the extension when the profile lacks the capability. The next release therefore still launches and keeps the wg-quick path until the Apple portal work is done. With the capability granted, the script requires the extension's own embedded profile, rejects a stub WireGuard bridge, signs the extension with its release/nightly entitlements, and verifies both sides agree. Workflows install Go before Release xcodebuilds, embed the optional APPLE_{RELEASE,NIGHTLY}_TUNNEL_PROVISIONING_PROFILE_BASE64 secrets into the extension, rename the nightly extension to com.cmuxterm.app.nightly.tunnel, and check the extension binary is universal and not the stub. strip-release-bundle.sh strips it. Each new script has behavior tests under tests/. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * build-wireguard-go: build the pinned module set in readonly mode The vendored go.mod/go.sum are the pinned module set; a build must fail rather than rewrite them, so the c-archive build runs with GOFLAGS=-mod=readonly. Verified the pinned set still builds universal with Go 1.26. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * build-wireguard-go: require Go only for Release builds Debug CI lanes (tests-build-and-lag, app-host unit tests) run on macOS runners without Go; a Debug build cannot load the extension anyway, so the stub engine is the right outcome there. Release builds still fail closed without Go, and the release workflows install it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * CloudTunnelCoordinator: adopt an already-connected tunnel; guard superseded cleanup The system extension outlives the app. After a crash or kill the VPN can already be connected when the next app instance first uses Cloud; startVPNTunnel on a live session posts no status change, so the start waited out the connect timeout, reported a failure, and stopped a working tunnel. The coordinator now reads the controller's current status after saving the configuration and adopts a connected link (or waits on a connecting one) instead of restarting it. A start superseded by a stop (an approval wait is not cancellable) that later fails no longer runs the cleanup stop, which could disconnect a newer start's tunnel; the cleanup is generation-guarded like setState. Tests cover both: adoption skips start(), and a superseded start's late failure leaves the newer tunnel and its call log untouched. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * Cloud tunnel: one top-level type per file Split the value types and the activation delegate out of the files that declared them alongside a protocol or enum, per the cmux file-organization policy: CloudPrivateNetworkUse, CloudPrivateNetworkNoopGate, CloudTunnelFallbackReason, CloudTunnelAppConsumers, CloudTunnelProviderConfiguration, CloudTunnelEnrollment, CloudTunnelProviderMessage (shared with the extension target), CloudTunnelStatus, SystemExtensionActivationDelegate. Nested types stay nested. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * AppDelegate: adopt the three-parameter machine-create launcher closure manaflow-ai#11773 gave MachineCreateCoordinator.Launch a progress callback and updated NewMachineSheetPresenter but not the Base-open launcher in AppDelegate, so main no longer compiles the app target (every app-host CI lane is red). Base open renders its output in the workspace's loading pane, so the progress stream has no reader here and is ignored. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * VMClientSocketCommands: share socketWorkerString with the tunnel verbs file vm.tunnel_applied (ported from main into VMClientSocketCommands+Tunnel.swift) reads its config_digest parameter through socketWorkerString, which was file-private. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * CloudTunnelCoordinator: stop inherited tunnels; back off after a failed start The system extension outlives the app, so a tunnel the previous instance left connected must still answer to quit, sign-out, and `cmux vpn down` before this instance has used Cloud. The NetworkExtension controller now reads the app's existing VPN configuration at launch (a passive preferences load, no prompt) and on demand, and tearDown stops a link the controller reports connected even when the coordinator's own state is off. After a failed start, Cloud uses no longer re-run enrollment, extension activation, and the configuration save on every dial: a 30 s failure backoff (clock-driven, cancellable) suppresses retries; `cmux vpn up` always retries. Tests cover the inherited-tunnel stop, the backoff, and the explicit bypass; the test doubles move to CloudTunnelTestFakes.swift to keep the suite under 500 lines. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * Cloud tunnel: lift nested Timing, Purpose, and the controller error to top-level types CloudTunnelTiming and CloudPrivateNetworkPurpose get their own files, and the controller's private not-installed error becomes CloudTunnelError.configurationNotInstalled (localized), so every file in Sources/Cloud/Tunnel declares exactly one type. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * CloudTunnelCoordinatorTests: no await inside the ?? autoclosure Swift rejects 'await' in an autoclosure that does not support concurrency; the fallback read of the coordinator's state is now a plain statement. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * Cloud tunnel: verify the real engine by its Go build info; prune dead broadcast subscribers eagerly Release signing and the release workflow now run scripts/verify-tunnel-extension-engine.sh, which requires the Go __go_buildinfo Mach-O section and an exported wgTurnOn. Both survive strip -S -x and dead-code stripping, unlike the stub's marker symbol (an unreferenced global a Release link may drop), so a stub can never pass as the real engine. The test builds the stub and, when Go is installed, the real archive, and checks both verdicts. CloudTunnelBroadcast drops subscribers as soon as their stream terminates (onTermination records the id behind a lock; subscribe and yield prune), so polling clients that subscribe and leave between state changes no longer accumulate. Covered by CloudTunnelBroadcastTests. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * Cloud tunnel: serialize starts behind stops, fail fast on adopted-link drops, redact runtime keys, enroll once - A Cloud use that arrives while a stop is draining (idle timer, vpn down, sign-out) now queues behind the tracked stop task instead of racing NetworkExtension with a start and failing into the backoff. - waitForLink seeds its connecting flag from the current link status, so an adopted connecting/reasserting link that drops fails fast instead of waiting out the connect timeout. - The provider strips private_key/preshared_key lines from the runtime configuration it returns to the app (CloudTunnelRuntimeConfigurationRedactor, shared with the extension target). - cmux vpn up on the app-managed backend reads vm.tunnel_status first and lets the app's start enroll once, instead of enrolling via vm.tunnel_config and again inside the start. - CloudTunnelBroadcast is lock-free again: termination is reported to the owning actor, which prunes under its own isolation. - The deadline helper and error mapping move to CloudTunnelCoordinator+Deadline to keep the coordinator well under the file budget. Tests: mid-stop use queues behind the stop; adopted connecting link fails fast; broadcast termination reporting; redactor.

…ge broke (manaflow-ai#11999) * Restore CMUXCLI.vmAttachTransportUnsupportedCode so cmux-cli compiles Every "Nightly macOS build" run on main since 19f51d5 fails in build-nightly-app with: CLI/cmux.swift:13798: error: type 'CMUXCLI' has no member 'vmAttachTransportUnsupportedCode' Two independent changes crossed. The Cloud VPN branch (manaflow-ai#11789, commit c9272d3) removed the cmux-tui fallback helpers from CLI/CMUXCLI+VMTui.swift, including this constant, because every Cloud route now goes through the WireGuard hub. Five hours later main gained a new use of the same constant in shouldFallbackFromForcedSSH (c8098d7). The branch's later merges of main combined both sides without a textual conflict, and the squash merge landed the dangling reference on main. PR CI never compiled Swift for manaflow-ai#11789: web-typecheck failed, so linux-preflight failed and every macOS job was skipped, while the no-op "CI status fallback" workflow satisfied the required ci-status check and auto-merge went ahead. Restore the constant in CLI/CMUXCLI+VMTui.swift. The control plane still answers 409 vm_attach_transport_unsupported (web/services/vms/routeHelpers.ts), and VMSSHCommandTests.testVMSSHAliasUsesCmuxRemoteWhenProviderSSHIsUnmanaged covers the forced-SSH fallback that reads it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EA5g4LcJ3QYAARgJjKCXvG * Drop stale SystemDefaultBrowserDetector.swift project entries The same squash merge (19f51d5, manaflow-ai#11789) re-added three cmux.xcodeproj entries for SystemDefaultBrowserDetector.swift: the PBXBuildFile, the PBXFileReference, and the cmux target's Sources entry. The file itself was deleted by the CEF revert (manaflow-ai#11966, e83b832), which also removed those entries on main; the VPN branch's merge of that revert kept them. The reference sits in no group, so Xcode resolves it against the project root and the app target fails with: error: Build input file cannot be found: '.../SystemDefaultBrowserDetector.swift' The nightly never reached this error because cmux-cli failed first. Remove the three entries, matching the revert. No other file reference in the project is orphaned or missing. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EA5g4LcJ3QYAARgJjKCXvG * Re-merge CmuxTuiSurfaceProviders.swift: keep main's state sync, apply the private-link port scan The VPN branch's merge of main (0ecbf91, "Merge origin/main into cloud tunnel PR branch") resolved seven conflict hunks in this file by taking the branch side, which: - left a `guard catalog.replaceResources(` with no `else` and Void `return`s inside `refresh(force:) -> Bool` (the app target did not parse; the nightly never got this far because cmux-cli failed first), - dropped main's `stop()` resets for `scheduledRefresh`, `stateRecoveryRefreshTask`, `watchedLink`, `changeWatcherID`, and `eventsFeedWarning`, - dropped main's asleep/unavailable publication through `replaceUnavailableCloudState` and the `eventsFeedWarning` link-error reporting, - kept `refreshDebounce` calls for a property main had removed. Redo the merge from git's automatic result: main's structure and logic stay, and the branch's intended changes are applied on top. Ports are no longer probed through provider exec; the cached scan is used until the cmux-tui link is up, then `ports(link:socketPath:)` refreshes `scannedPorts`/`currentPorts` for `publish`. The desktop row carries its private noVNC URL everywhere it is created (`desktopDisplayResource()`), the provider preview-endpoint machinery stays removed, and the old `VMTunnelManager.privateRouteBlocker()` text stays removed because that API no longer exists. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EA5g4LcJ3QYAARgJjKCXvG * Re-merge CloudMachineLink.swift: restore the events recovery state the merge dropped The same merge (0ecbf91) resolved six hunks here by taking the branch side and lost main's events-subscription state: the eight stored properties (`eventsSubscriptionID`, `eventsReaderTask`, `eventsCursor`, `eventsRecoveryClock`, `eventsRecoveryPolicy`, `eventsRecoveryTask`, `eventsStabilityTask`, `eventsRecoveryPhase`) while every use of them survived, the `eventsCursor = nil; resetEventsRecovery()` at the start of `connect`, the `.connected` change event, the subscription id and cursor in `startEventsSubscription`, and the reader/recovery resets in `disconnect()` and `linkProcessDidExit`. Build error on main after the constant fix: Sources/Cloud/CloudMachineLink.swift:166: value of type 'CloudMachineLink' has no member 'eventsRecoveryClock' Keep the branch's additions (hub lease release, `eventsProcessExit` with `terminateAndWait` before a replacement reader, async `disconnect`/`linkProcessDidExit`) on top of main's logic. `startEventsSubscription(socketPath:cursor:)` is now async because it waits for the previous events child; `restartEventsSubscription`, `resumeEventsSubscription`, and `recoverEventsSubscription` propagate that. Callers already await them (actor). Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EA5g4LcJ3QYAARgJjKCXvG * Restore network_addresses plumbing and the vm terminal rename contract row Two more main-side pieces the 0ecbf91 merge dropped while keeping the rest of the feature (c8098d7): the `vm.cmux_remote_info` socket reply no longer carried `network_addresses` even though the CLI still parses it, and `cmux vm open --json` no longer forwarded it. Put both back so the chain works end to end again. Also restore the `vm terminal rename` row in docs/cli-contract.md, which the merge removed from the CLI contract table.

…rkflow permissions guard, screenshot decoupling, notarization hardening) (manaflow-ai#12157) * ci: guard reusable-workflow permission grants (red on main's shape) GitHub validates a reusable workflow's permissions against the calling job when it parses the caller. A callee that requests a scope the caller does not grant fails the whole caller run at startup, before any job runs. That is what blocks the stable release today: release.yml calls ios-screenshots.yml, which requests `actions: write` while release.yml grants none (manaflow-ai#12149). Add scripts/ci/check_reusable_workflow_permissions.py (python3 stdlib only) that walks every local `uses: ./.github/workflows/*.yml` call, computes the calling job's grant (job block, else workflow block, else the repository default) and the callee's request (max over its workflow block and every job block, gated jobs included, mirroring 4b9720d), follows nested calls with the intermediate grant, and fails on any scope that asks for more. tests/test_ci_reusable_workflow_permissions.py covers the rule on fixture trees (the exact manaflow-ai#12149 shape, shorthands, job-level overrides, repository defaults, nesting, missing callees) and then runs the checker on the real tree, which fails until the next commit fixes the workflows. Wired into the workflow-guard-tests job in ci.yml. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * ci: stop ios-screenshots.yml requesting actions: write (fixes release startup) The screenshot workflow declared `actions: write` since manaflow-ai#6697, but no step ever used it: checkout runs with persist-credentials disabled, the two artifact uploads use the runner's artifact token, the capture is a DEBUG simulator build, and the App Store Connect upload path authenticates with an API key. When manaflow-ai#11342 made release.yml call this workflow, GitHub compared the callee's block with the caller's grant (contents/attestations/id-token only) and refused the release workflow at parse time: startup_failure, no job run, for tag pushes and dispatches alike (manaflow-ai#12149). Reduce the callee to `contents: read`, the minimum its steps use. Widening release.yml instead would have handed a UI-test job the ability to cancel or dispatch runs for no benefit. The guard added in the previous commit now passes on the tree. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: do not gate build-sign-notarize on iOS screenshot capture manaflow-ai#11342 made build-sign-notarize need generate-ios-screenshots ("gates build-sign-notarize on screenshot success"). The DMG never consumes those artifacts: nothing in build-sign-notarize downloads them, and the App Store tooling (ios/scripts/appstore-shots.sh capture) dispatches its own ios-screenshots.yml run rather than reading a release run. What the gate did do was make every stable macOS release wait for, and fail with, a 300-minute simulator capture across nine locales on shared macOS runners, a lane that had "not compiled on main for days" before manaflow-ai#11342 healed it. Keep the capture in release.yml as a sibling job, so every tag still gets screenshots at the exact release ref and a failed capture still turns the run red, but drop it from build-sign-notarize.needs. Trade-off: a green macOS release no longer implies the screenshot capture succeeded; the run conclusion still does. tests/test_ci_release_ios_screenshots_decoupled.sh pins the policy (fails on main's needs list, passes here) and runs in workflow-guard-tests. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: give the screenshot capture job only contents: read and no secrets The screenshot job runs a DEBUG simulator UI test after `brew install` of fastlane and imagemagick. Capture-only needs to read the repository and nothing else: checkout runs with persist-credentials disabled, artifact uploads use the runner's artifact token, and the App Store Connect upload path in ios-screenshots.yml is gated to workflow_dispatch from main, so it is unreachable from a release run whatever `upload` says. Set job-level `permissions: contents: read` on the calling job (the pattern the cmux-tui callers already use) instead of passing the workflow's contents/attestations/id-token write grant through, and drop `secrets: inherit`, which handed every repository secret (Developer ID certificate and password, notarization credentials, Sparkle private key, R2 keys, Sentry token, ASC key) to that job for no benefit. Trade-off: if the release lane ever wants the ASC upload, it must add `secrets: inherit` back together with `upload: true` and relax the callee's dispatch-only guard. That should be a deliberate change. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: let the Sparkle monotonic guard warn on non-tag dry runs release.yml runs tests/test_ci_sparkle_build_monotonic.sh at the top of build-sign-notarize. On plain main it fails (CURRENT_PROJECT_VERSION 102 equals the published 0.64.22 build), which is correct for a tag push about to publish but wrong for the workflow's built-in dry run: a non-tag workflow_dispatch publishes nothing and, by design, runs from a branch that has not been bumped yet. The dry run was therefore impossible without a throwaway bump commit. Chosen fix: a CMUX_SPARKLE_MONOTONIC_MODE switch on the guard, `enforce` by default (tag pushes, scripts/release-pretag-guard.sh) and `warn` when release.yml runs from anything but refs/tags/*. Rejected alternative: running the dry run from a throwaway branch with a temporary bump, which would validate a commit that never merges and leave the pipeline un-dry-runnable for everyone else. tests/test_sparkle_build_monotonic_modes.sh drives the guard against fixture project files and a local appcast (stale fails in enforce and by default, warns in warn mode, bumped passes in both, unreachable appcast soft-passes, unknown mode fails) and pins the ref-based selection in release.yml. Wired into workflow-guard-tests. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * ci: give Gatekeeper twenty minutes to see a fresh notarization ticket scripts/ci/notarize-computer-use-helper.sh polls `spctl` on the standalone Computer Use helper after stapling because Apple's CDN publishes the ticket some time after notarytool reports Accepted. The budget was 20 x 15s. Nightly run 34208928547 (2026-09-08) exhausted it: Accepted at 09:51:28, still "Unnotarized Developer ID" at 09:56:18, exit 3, whole universal lane failed, while the arm64 and x86_64 lanes passed in the same window. Raise the default to 80 x 15s (twenty minutes) and announce the budget on the first rejection so a log reader can tell propagation from a hang. Trade-off: a genuinely rejected helper now takes up to twenty minutes to fail instead of five, which only delays an already-lost release; a short budget failed good releases, each costing a full rebuild and a human retry. Both knobs remain env-configurable (CMUX_GATEKEEPER_ASSESS_ATTEMPTS/_DELAY_SECONDS). nightly's signing job has an 80-minute timeout with a 7-10 minute typical duration, so the budget fits there; release.yml's timeout is raised in the next commit. tests/test_notarize_computer_use_helper.sh now pins the defaults (at least 1200s, polled at least every 30s, env-configurable literals) and the budget announcement, alongside the existing override and give-up coverage. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: raise build-sign-notarize timeout to 90 minutes v0.64.22's build-sign-notarize took 39.8 minutes on 2026-08-03. Since then the job gained the Cloud tunnel system extension and its Go engine build (manaflow-ai#11789), the universal diff sidecar and cmux-tui client install (manaflow-ai#12006), two extra smoke launches, and a Gatekeeper propagation wait that can now run twenty minutes on its own. A 60-minute ceiling leaves no room for a slow notarytool day, and a timeout mid-notarization wastes the whole build. 90 minutes covers the measured baseline plus the known variable waits with headroom while still bounding a hung job on a shared self-hosted runner. To be re-checked against the dry-run duration for this branch: the timeout must stay at least 25 percent above it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * release: name the tunnel extension by its bundle identifier, not its App ID The first release dry run that could start after the permission fix (run 34222835589) failed 30 minutes in, at "Verify binary architectures": error: system extension identifier is 'com.cmuxterm.app.tunnel', expected '7WLXT3NR37.com.cmuxterm.app.tunnel' manaflow-ai#11789 passed the team-prefixed App ID to scripts/normalize-system-extension-bundle.sh and looked for the tunnel binary under 7WLXT3NR37.com.cmuxterm.app.tunnel.systemextension. The Release build's PRODUCT_BUNDLE_IDENTIFIER for the extension is com.cmuxterm.app.tunnel; only NEMachServiceName ($(CMUX_TEAM_ID_PREFIX)$(PRODUCT_BUNDLE_IDENTIFIER)) and the provisioning profile's com.apple.application-identifier carry the team prefix, and the app activates whatever CFBundleIdentifier the bundled extension declares. nightly.yml already does it this way and ships com.cmuxterm.app.nightly.tunnel.systemextension with a profile for 7WLXT3NR37.com.cmuxterm.app.nightly.tunnel (run 34220568401). The mistake was invisible until now because release.yml could not start at all. Use the bundle identifier for the normalize call and the directory the verify step inspects; keep the App ID for the profile check. tests/test_ci_release_tunnel_identifiers.sh derives all three from cmux.xcodeproj/project.pbxproj (fails on main's release.yml, passes here) and runs in workflow-guard-tests. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * Fix main's package-test compile error and Swift warning-budget violations main is red for every branch that routes the macOS lane (manaflow-ai#12161, manaflow-ai#12165), which keeps ci-status from ever reporting green on this release-pipeline PR. Fix both at the root rather than refreshing the budget: - swift-package-tests: FakeTerminalEngine.swift gained a `UUID` parameter in manaflow-ai#10564 but imports only GhosttyKit. Add `import Foundation`. - tests-build-and-lag (scripts/swift_warning_budget.py, actual > budget): * AppDelegate+PaneMemoryGuardrail.swift: parenthesize the two `compactMap` closures inside the `guard` condition ("trailing closure in this context is confusable with the body of the statement"). * SessionIndexTableController.swift: the bounds-change observer block is typed @sendable in the current SDK, so referencing `isApplyingRows` and `reconcilePresentation(in:)` warned. The block is delivered on `queue: .main`, so run it under `MainActor.assumeIsolated`, the same pattern SidebarWorkspaceRowCellView uses; no async hop, same timing. * CmuxTuiSnapshotParser.swift: `switch resourceID.kind` already covers every SurfaceResourceKind case (terminal, display, browser), so the `default: continue` could never run. Remove it; a new case now fails to compile here instead of being silently skipped. * SurfaceCatalogModel.swift: `if let rowID,` rebound a value the body never read; test `rowID != nil` instead. * TerminalController.swift: `payload` in the `.delivered` branch is never mutated; make it `let`. Every change is behavior-preserving. Verified with `swiftc -parse` on each file locally (no app build on the shared machine); the routed CI lane proves the build and the budget.

This is the output of scripts/normalize-pbxproj.py: three lines reordered, no identifier or setting changed.

The job log shows why: ./scripts/sparkle_generate_appcast.sh: line 93: delta_args[@]: unbound variable A tag push would have published a GitHub Release without appcast.xml, so no Sparkle client would ever be offered the update, and the R2 stable appcast upload would then fail after the release already existed. tests/test_sparkle_generate_appcast_no_deltas.sh runs the real script with fake git/xcodebuild/generate_appcast/sign_update tools under every bash on the machine (/bin/bash 3.2 on macOS reproduces the bug; bash 5 never did) and requires a signed appcast at the requested output path with no delta arguments when there are no previous archives, and with --maximum-deltas when there are. It also requires release.yml to verify the feed after generation instead of trusting the exit status. Fails on main's script and workflow; the next commit fixes both. Wired into workflow-guard-tests.

In bash 4.4+ an empty array expands to nothing; in bash 3.2 (macOS /bin/bash, which `#!/usr/bin/env bash` resolves to on the release runner) it is an "unbound variable" error under `set -u`. Worse, with the script's EXIT trap bash 3.2 then exits 0, so the step passed and no appcast was written. Nightly always has previous archives (delta_args non-empty) and was never affected; the stable release lane never has them and has been broken since 2026-09-03, unnoticed because release.yml could not start at all (manaflow-ai#12149). Expand the array as ${delta_args[@]+"${delta_args[@]}"}, which is empty when the array is empty in every bash. In release.yml, verify after generation that appcast.xml exists, carries sparkle:edSignature and references cmux-macos.dmg before anything uploads it: the exit status alone is not a reliable signal on bash 3.2.

A missing signal must fail closed when the run is about to publish. enforce mode now fails with an explanation when the published build is unknown; warn mode (non-tag dry runs) keeps the soft pass because it publishes nothing. curl retries transient failures (3 x 2s by default, overridable so the tests exercise the unreachable path without waiting). tests/test_sparkle_build_monotonic_modes.sh covers enforce, default and warn against an unreachable appcast.

It updated the Python hook tests to the new wire contract but not ClaudeHookLifecycleCleanupTests, whose two moved-pane tests still expected the removed command. They fail on main in the strict app-host agent-notification step (shard 6), unnoticed because manaflow-ai#11976's PR CI never routed the macOS lane. Assert the new contract instead: the journal event for the hook names the re-homed workspace and the live pane (via the existing AgentJournalAppendCapture parser), and nothing still wipes the whole destination workspace. SessionEnd keeps sending the v1 command, so its tests are unchanged. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * ci: make app-host hangs fail in minutes instead of the 75-minute job timeout Every macOS lane run since 2026-09-03 has ended with app-host shards "cancelled" at the 75-minute job timeout. Today's logs (run 34236235360, shards 1/2/4, both attempts) show the mechanism, and it is two plumbing defects rather than the tests: 1. scripts/ci/xcodebuild_noninteractive.py resets its 300s idle deadline on every output chunk. Since manaflow-ai#11755 (merged 2026-09-03T02:09Z, after the last green lane at 2026-09-02T09:21Z) the app host logs every Cloud API poll, `[CloudVM] GET /api/vm not_signed_in`, every 45 seconds. A test host hung inside a WebKit page load (WebContent XPC: "Could not signal service ... 113") therefore never looks idle, so the wrapper's kill and retry path, which handled the same WebKit failure on the 09-02 green run, never fires. 2. The tolerant batch watchdog in ci.yml (1800s) killed only the console-session launcher and left the lock wrapper, xcodebuild and the app host alive; the app host kept the `| tee` pipe open, so the step sat idle from "timeout after 1800s; terminating" until the job timeout. Fixes: - CMUX_XCODEBUILD_NONINTERACTIVE_IDLE_IGNORE_RE: output lines matching it do not count as progress. run-app-host-xcodebuild.sh defaults it to the Cloud poll line (an empty value restores counting everything; an invalid regex fails closed with exit 2). Real output still resets the clock, so a slow but progressing batch is unaffected. - The ci.yml batch runner writes xcodebuild output to the capture file and streams it with a detached tail, kills the whole process tree (pgrep -P recursion, TERM then KILL) when the batch budget expires, and reads both the streamed and per-batch captures for the SwiftPM retry heuristic. Behavior tests: tests/test_ci_xcodebuild_noninteractive_helper.py drives a child that prints only the keepalive every 50ms (finishes without the pattern, idles out at 0.3s with it, invalid pattern exits 2); tests/test_ci_change_areas.py runs the real step script against a runner that hangs and leaves a grandchild holding stdout, and requires exit 124 within seconds with the grandchild dead. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * ci: keep the canonical OUTPUT capture line the SPM-retry guard pins tests/test_ci_unit_test_spm_retry.sh requires `OUTPUT=$(cat "$TEST_OUTPUT")` verbatim in the app-host step; the previous commit folded the per-batch capture files into that line and turned workflow-guard-tests red. Keep the pinned line and append the per-batch captures on the next line instead. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsJWT2S5Mx2Wv3XGFih8as * ci: keep a watchdog-killed app-host batch terminal; drop the wall-clock assert CodeRabbit on manaflow-ai#12157: the expected-failure normalization in run_unit_test_batch greps the capture for the last "Executed ... failures" summary and returns success on "(0 unexpected)". After the watchdog kills a batch (status 124) the capture can still hold an earlier attempt's summary (run-app-host-xcodebuild.sh retries into the same file), so a terminated batch could be reported as passed. Treat 124 as terminal before the normalization. The hung-runner behavior test now prints a decoy "(0 unexpected)" summary before hanging and requires the step to stay at 124 without the "All failures ... are expected" message. Also drop the `elapsed < 60` assertion from that test: the harness's 120s subprocess timeout already bounds a runaway step, and a hard wall-clock ceiling only adds scheduler-delay flakes.

The shared accept loop fulfills that expectation when the listener closes at the end of the helper, so XCTest ended `testCoderouterUnknownVerbStillPassesThroughToTheInstalledCLI` and `testCoderouterClaudeAddOAuthTokenRejectsAPIKeyShapeBeforeTheSocket` with "Failed due to unwaited expectation", which it counts as an *unexpected* failure. Since manaflow-ai#12207 the app-host batch classifier fails a batch on any unexpected failure, so this one test turned shard 5 (and the sibling test shard 6) red on main and on every PR: run 34401456032, main run 34342638735 attempts 1 and 2. Serve those two tests from the detached mock server instead, which owns no expectation, and keep the waited path for every other Coderouter test. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * ci: rerun a remote tmux mirror suite once after an app-host crash The non-tolerant "Run remote tmux mirror detach and placement regressions" gate on shard 6 fails whenever the app host crashes mid-suite, which manaflow-ai#9348 documents as nondeterministic: the crash point moves between tests and the relaunched host passes the rest (run 34401456032 crashed in dedicatedWindowSocketDefaultsToFocusNeutral; the previous run and both main attempts passed the same step). Capture each suite's output and rerun the suite exactly once, only when xcodebuild printed "Restarting after unexpected exit, crash, or test timeout". An assertion failure never earns a rerun and a second crash still fails the shard, so the gate keeps rejecting real regressions. tests/test_ci_change_areas.py drives the real step script against a fake console runner: crash-then-pass is green with three invocations, an assertion failure exits 65 after one invocation, and two crashes exit 65 after two.

When the first connection's handler reached that check after the replacement had already recorded, it promoted `first` instead, superseded the freshly admitted replacement, and the replacement's own markUsable returned false: "Expectation failed: await admission.markUsable()" at CmxIrohEndpointServerTests.swift:353 in CI run 34414741413 (swift-package-tests), while the previous run passed the same code. Admit before recording so the test's `recorder.next()` proves `first` is active before `replacement` is enqueued, and promote only the replacement by identity. The suite passes three consecutive local runs. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * cmuxTests: serialize the stdin pump suite and bound its blocking waits Shard 3 of CI run 34414741413 hung three times at the app-host wrapper's 300s idle timeout in the same batch. The hang sample shows SSHPTYAttachReconnectInputFilterTests.stdinPumpFiltersReadyInputBeforeStopSignal parked in stopFiltering() -> read() on the stop-acknowledgement pipe with every other visible cooperative-pool thread also inside a test body's synchronous wait. The pump under test is a detached task that needs one of those same threads, and the five pump tests each hold a thread for the ~13s reconnect probe deadline while running concurrently, so the suite can leave no thread for any pump (the family issue manaflow-ai#12180 tracks). Run the suite serialized so at most one test parks a thread at a time, and bound every wait: stopFiltering now takes a 30s acknowledgement timeout and must succeed, and the EOF/exact reads poll with the same deadline. A pump that never gets scheduled now fails its test inside the batch instead of parking the shard until the idle timeout retries are exhausted. The two assertions in this suite that already fail on main (readUntilEOF == forwardedInput in stdinPumpFiltersReadyInputBeforeStopSignal and stdinPumpKeepsFilteringLateProbeRepliesAfterInitialDrain) are unchanged; the batch classifier tolerates them today.

What
The cmux app can now own the WireGuard tunnel into the user's private Cloud VM network as a real macOS VPN, through a bundled NetworkExtension packet-tunnel system extension. On a build whose signing carries the capability, opening a Cloud machine brings the tunnel up with no
cmux vpn up, no sudo, no wg-quick, no Homebrew; the tunnel stays off until the user actually uses cmux Cloud and stops again when no Cloud sessions remain. Builds without the capability fail closed for Cloud browser access; terminal traffic continues through the user-space WireGuard hub.Closes #11760
Architecture (and the two places this deliberately departs from the issue text)
System extension, not app extension. The issue asked for a
packet-tunnel-providerapp extension. macOS only loads NetworkExtension app extensions for apps distributed through the Mac App Store; cmux ships as a Developer ID app (DMG, Homebrew cask, Sparkle). An appex would build and sign but never load. The provider is therefore a network system extension (cmuxTunnel.systemextension, bundle id<app bundle id>.tunnel, embedded atContents/Library/SystemExtensions) activated withOSSystemExtensionRequest, and the entitlement value ispacket-tunnel-provider-systemextensionpluscom.apple.developer.system-extension.install. Two consequences the user will see once the capability ships: the first activation on a Mac asks for approval in System Settings › General › Login Items & Extensions, and macOS refuses to load system extensions from an app outside/Applications(the app reports that as an actionable error).Config transport is
NETunnelProviderProtocol.providerConfiguration, not an App Group container. System extensions run as root and cannot read the user's group container or keychain. The completed wg-quick config (private key filled in) travels inside the VPN configuration the app saves, which lives in the root-only NetworkExtension preference store, strictly more protected than the 0600 file the wg-quick path keeps. The team-prefixed App Group (7WLXT3NR37.com.cmuxterm.app[.nightly]) is still declared on both bundles because the extension'sNEMachServiceNamemust be prefixed by one; team-prefixed groups need no portal registration.Extension target (
TunnelExtension/, targetcmuxTunnelExtension)PacketTunnelProvider(NEPacketTunnelProvider) reads the wg-quick config fromproviderConfiguration, parses it, and runs it through WireGuardKit'sWireGuardAdapter. Config parse errors are logged by rule name only (the private key is one of the payloads).handleAppMessageanswers the runtime configuration (peers, handshakes, transfer) with the private and pre-shared keys stripped.vendor/WireGuardKit(MIT; upstream wireguard-apple2fec12a6, tag 1.0.16-27) as a local SwiftPM package, with the upstream app target's wg-quick parser moved into the kit and madepublic, and one header fix for Xcode 26's strict module imports.vendor/WireGuardKit/README.mdrecords every modification and the update procedure.scripts/build-wireguard-go.sh(per-archgo build -buildmode=c-archivein readonly module mode, lipo'd). Release builds require Go and fail without it (the release workflows install it); Debug builds without Go, including the Debug CI lanes and fleet dev builds, get a loud stub archive (every wg* symbol fails, marker symbolcmux_wireguard_go_bridge_is_stub), and release signing refuses to ship a stub. Upstream's Go-runtime patch (timers counting sleep, an iOS concern) is intentionally not applied; the adapter re-handshakes via its network-path monitor after wake.App side (
Sources/Cloud/Tunnel/)CloudTunnelBackendSelectorpicks the backend from the running binary: signedpacket-tunnel-provider-systemextension+system-extension.install+ a.systemextensionactually present in the bundle → NetworkExtension; anything missing → unavailable with a named reason.VMTunnelManager.networkExtensionAvailable()now delegates to it.CloudTunnelCoordinator(actor) is the state machine:off → starting → (awaitingApproval) → up → stopping → off,failed(message). It enrolls (idempotently) throughVMTunnelManager, saves the VPN configuration throughNetworkExtensionTunnelController(NETunnelProviderManager,isOnDemandEnabled = false, no on-demand rules), activates the extension throughSystemExtensionActivator, and waits forNEVPNStatusto reach connected. Because the system extension outlives the app, a tunnel left connected by a previous instance is adopted on the next Cloud use instead of restarted, and quit / sign-out /cmux vpn downstill stop it before any Cloud use (the controller reads the existing VPN configuration at launch, a passive preferences load with no prompt). A start superseded by a stop (an approval wait is not cancellable) can never tear down a newer start's tunnel; a Cloud use that arrives while a stop is draining queues behind it instead of racing NetworkExtension; and after a failed start Cloud uses back off for 30 s instead of re-running enrollment, activation, and the configuration save on every dial (cmux vpn upalways retries).VMClienttakes aCloudPrivateNetworkGate; every endpoint-minting call (openSSH,openAttach,openCmuxRemote,openSession,openPort) starts the tunnel concurrently with the HTTP request and waits a bounded readiness budget (20 s) before returning the endpoint, so the dial finds the route in place.
