Inline comments:
In `@CLI/CMUXCLI`+VMTransfer.swift:
- Line 608: The VM size presets are duplicated across parsing, usage text, and
diagnostics, causing `24g` to be advertised inconsistently. Define or reuse one
shared preset list for `parseCloudVMSize`, the `vmRunUsage` site at
CLI/CMUXCLI+VMTransfer.swift:608-608, the `vmRouteUsage` site at
CLI/CMUXCLI+VMTransfer.swift:1093-1093, and both validation messages; ensure
every location reflects the same accepted sizes, or remove `24g` everywhere if
parsing does not support it.
In `@CLI/CMUXCLI`+VMTui.swift:
- Around line 781-818: Update the argument validation in the workspace command
handler and runVMTerminalCommand: require exactly two positional arguments for
workspace open/close and exactly three for terminal close, while rejecting any
flags other than the explicitly supported options. Return the existing usage
errors before invoking vm.workspace_open, vm.workspace_close, or
vm.terminal_close when validation fails.
In `@cmux-tui/crates/chatmux-relay/src/pty.rs`:
- Around line 58-67: Update random_hex to propagate getrandom::fill failures
instead of discarding them, returning a Result so no deterministic zero-valued
identity is produced. Adjust the relay transport-id and tunnel pty_id call sites
in session.rs and tunnel_terminal.rs to handle the error by refusing to start
the transport.
- Around line 889-901: Update handle_frame and the emit_output, emit_exit, and
authorize flows to resolve authorization state and reply sinks from each
attachment’s owning transport_id rather than the shared Inner::auth snapshot.
Keep transport-specific state separate for the relay socket and tunnel listener
so one transport cannot overwrite another’s sink or authorization context.
In `@cmux-tui/crates/cmux-tui-core/src/resource_api.rs`:
- Around line 652-662: Update the snapshot construction around the terminal
validation loop to collect each missing-host terminal ID in a dangling-terminal
set, then remove those IDs from terminal_order before the terminal projection
loop. Preserve the existing warning log and ensure dangling terminals are
excluded instead of causing snapshot failure.
In `@cmux-tui/docs/TECH-DEBT-CHANGELOG.md`:
- Line 9: Update the `#11044` entry in TECH-DEBT-CHANGELOG.md so it is not
presented as a merged item with an exact rollback command while the PR remains
open; either remove it from the merged table or mark the rollback as pending
until a real merge SHA is available.
In `@cmuxTests/NewMachineModelTests.swift`:
- Around line 173-217: Update the NewMachineModel failure-path tests to expect
localized, sanitized product copy in errorText instead of raw CLI output,
including retryable creation failures and created-but-open-failed cases.
Preserve assertions for parsed machine IDs and retry behavior, while verifying
diagnostic CLI details are handled through internal logging rather than exposed
by NewMachineSheet.
In `@docs/cli-contract.md`:
- Line 221: The vm new/create table row must remain two columns. Update the
--size value in the row to avoid pipe characters, using a comma-separated list
of supported sizes while preserving the documented options and behavior.
- Around line 217-220: Update the cmux vm --help contract probe near the
expected output to include the documented workspace and terminal subcommand
names, keeping the probe aligned with the entries for vm.workspace_new,
vm.workspace_open, vm.workspace_close, and vm.terminal_close.
In `@Resources/Localizable.xcstrings`:
- Around line 269548-269554: Update NewMachineModel.create() to sanitize
combined CLI output before assigning errorText or interpolating it into failure
messages, including machines.new.error.createdOpenFailed. Replace raw command
output with a short product-safe message while preserving the existing
error-handling flow.
In `@Sources/AppDelegate.swift`:
- Around line 8564-8571: Update launchCloudVMBaseOpen so its
immediate-start-failure path invokes onCompletion as well as showing the
loading-panel failure. Ensure both the direct retry and sheet launch callers
receive the callback when CloudVMActionLauncher.shared.start does not start,
while preserving the existing launcher completion behavior for successful
starts.
- Around line 8517-8562: Add a liveness check immediately after awaiting
Self.cloudVMFleetPage() in the Task, verifying that workspace is still present
in tabManager.tabs; return early when it has been closed. Ensure both the
NewMachineSheetPresenter path and launchCloudVMBaseOpen path are skipped for
dismissed placeholder workspaces.
In `@Sources/Cloud/CloudMachineLink.swift`:
- Around line 50-62: Update error handling around errorText and all assignments
to linkError or SurfaceBrowserPlaceholder.failed so control-plane and
child-process failures are converted to localized, product-safe messages before
reaching product UI. Keep provider details and child-process stderr confined to
sanitized logs, reusing the existing error-handling symbols and preserving the
UI’s failure behavior.
In `@Sources/Cloud/CloudMachineLinkManager.swift`:
- Around line 95-105: Update the connection diagnostics in
CloudMachineLinkManager to avoid logging sensitive dynamic values: remove or
redact connected.socketPath, VMClientError URLs/details, and child-process
stderr, and log only fixed failure categories or explicitly sanitized fields in
the cloud.link.connected and cloud.link.failed messages.
In `@Sources/Cloud/NewMachineModel.swift`:
- Around line 62-75: Replace the localized string parsing in
createdMachineID(fromOutput:) with a reliable structured source for the created
machine ID, such as adding a typed ID field to CloudVMActionLauncher.Completion
and consuming it in the creation flow. Ensure successful creation preserves the
ID even when terminal attachment fails, so Retry does not issue a second vm new
command.
- Around line 187-202: The completion handling in NewMachineModel must stop
assigning raw completion.output to errorText. Replace both output-based
user-facing messages, including the createdMachineID failure path, with
localized product-safe errors, while sending sanitized diagnostics through the
existing sanitizedCloudVMStartOutput mechanism and internal logging.
In `@Sources/Cloud/NewMachineSheetPresenter.swift`:
- Around line 22-25: Update NewMachineSheetPresenter.present to return an
explicit result indicating whether presentation started, including the
isPresenting branch as not presented while preserving its window-fronting
behavior. Update the AppDelegate caller that creates the placeholder workspace
to inspect this result and close the placeholder when presentation did not
start, ensuring cleanup does not depend solely on model.onFinished.
- Around line 29-30: Update the fallback window creation in
NewMachineSheetPresenter to assign a stable cmux.* identifier and register that
identifier with the auxiliary-window policy used by
cmuxWindowShouldOwnCloseShortcut. Ensure the standalone key window participates
in the shared close-shortcut ownership behavior.
- Around line 9-14: Remove the process-wide NewMachineSheetPresenter.shared
singleton and make NewMachineSheetPresenter constructable with its sheetWindow,
hostWindow, and model state owned by an injected coordinator. Update the
composition root to create and inject that presenter/coordinator instance,
preserving the existing presentation behavior without ambient global mutable
state.
- Around line 35-37: Update the model.onFinished assignment in
NewMachineSheetPresenter to preserve and invoke the completion handler
previously installed by AppDelegate before dismissing the sheet. Ensure
cancellation closes the placeholder workspace and reports completion while
retaining the existing dismiss behavior.
In `@Sources/Cloud/VMClientSocketCommands.swift`:
- Around line 582-585: Mark the SocketWorkerKindError value type as nonisolated
so it can be returned by the nonisolated socketWorkerMachineKind path without
Swift 6 actor-isolation errors.
In `@Sources/Surfaces/CmuxTuiSurfaceProviders.swift`:
- Around line 318-330: The endpoint-minting Task in the provider flow must be
owned and cancellable by provider lifecycle. Track each task by paneID, cancel
and remove the corresponding tasks in both stop() and
discardMaterialization(_:), and ensure completed tasks are cleaned up while
preserving the existing endpoint navigation and error handling.
In `@Sources/Surfaces/SurfacePaneFactory.swift`:
- Around line 237-246: Update SurfacePaneFactory.failed to stop including the
raw error argument in the browser pane detail; use localized product-level
recovery text instead, while preserving the retry hint. Keep technical
connection-error details out of the rendered placeholder and retain them only in
logging at the caller.
In `@Sources/Surfaces/SurfaceSocketCommands.swift`:
- Around line 281-287: Update the resource filter in the workspace lookup to
match when any entry in each resource’s remoteWorkspaces has an id equal to
remoteWorkspaceID, rather than checking only remoteWorkspace. Preserve the
existing workspace selection, error handling, and resource grouping behavior.
In `@web/app/api/vm/route.ts`:
- Around line 219-227: Move all newly added user-facing English text to the
locale-specific localization sources and add matching entries for every
supported locale. Update the invalid-kind response around isVmImageKind and
vmErrorResponse in web/app/api/vm/route.ts#L219-L227, both response paths in
web/services/vms/routeHelpers.ts#L347-L360 and `#L493-L509`, and publish the
additions through localized documentation in docs/cli-contract.md#L217-L222,
skills/cmux-cloud-vm/SKILL.md#L51-L51, and
skills/cmux-cloud-vm/references/commands.md#L13-L16 and `#L67-L68`.
In `@web/services/vms/images/blaxel/start-vnc.sh`:
- Around line 73-88: Replace the polling loop launched by the
cmux-desktop-resize-watch process with an event-driven display or noVNC resize
notification. On each resize event, invoke the existing set_wallpaper routine
and refresh tint2, preserving the current change-detection behavior where
applicable; remove the xdpyinfo polling and fixed sleep entirely.
In `@web/services/vms/images/resolver.ts`:
- Around line 381-392: Localize VM image configuration errors across all
affected paths. In web/services/vms/images/resolver.ts lines 381-392, accept
localized message/action strings from the request locale instead of hardcoded
English; update web/app/api/vm/base/routeShared.ts lines 265-276 and
web/app/api/vm/route.ts callers of reportVmImageConfigError to obtain and pass
the locale-specific strings, adding translations for every supported locale. In
Sources/Cloud/VMClientSocketCommands.swift lines 377-385, localize the Swift
socket message with String(localized:defaultValue:).
In `@web/services/vms/README.md`:
- Around line 71-80: The operational deployment and rollback guidance must match
the new image policy: update the affected instructions to cover
DAYTONA_SANDBOX_SNAPSHOT, BLAXEL_SANDBOX_IMAGE, and
BLAXEL_SANDBOX_DESKTOP_IMAGE, and revise the deployed-create behavior around
defaultForKind to explicitly state whether that fallback is supported. Ensure
the documented configuration and rollback steps cover all newly supported
providers and machine kinds.
In `@web/tests/telemetry-sampler.test.ts`:
- Around line 93-109: Move the OpenTelemetry provider and context-manager setup
from describe-time into beforeEach, ensuring each test creates and registers
fresh instances. Move provider.shutdown, trace.disable, and otelContext.disable
into afterEach so globals are cleaned up after every test; update references
such as exporter and provider as needed to remain test-scoped.

Outside diff comments:
In `@cmux-tui/crates/cmux-tui/src/app.rs`:
- Around line 14535-14552: Add a short comment immediately above the
!Self::mouse_opens_cmux_context_menu(mouse) guard explaining that it must remain
despite route pre-normalization, because removing it causes browser-pane
context-menu presses to be discarded before dispatch_terminal_input.
In `@Sources/Cloud/CloudMachineLink.swift`:
- Around line 145-156: Update the socket-wait flow around
CloudLinkFirstValue.result so cancellation terminates and cleans up the
timed-out cmux-tui process, allowing the task group to return promptly when the
timeout task wins. Add a regression test covering a silent endpoint and verify
connect completes with the timeout error rather than remaining blocked.
In `@Sources/Cloud/MachinesPanelViewModel.swift`:
- Around line 141-145: Replace the image-based desktop checks in
CmuxTuiSurfaceProvider with summary.resolvedKind.hasDesktop at each affected
decision point, including the resource replacement path, so all desktop behavior
uses the resolved machine kind. Add a regression test covering kind == .desktop
with an image lacking legacy desktop tokens, verifying the machine is treated as
desktop and display resources are provided.
In `@Sources/Cloud/VMClient.swift`:
- Around line 260-273: The fork and restore workflows must preserve the
authoritative machine kind through their responses. Update both routes to
include kind, ensure VMHandle carries it through the workflow, and update
VMClient decoding so VMSummary.kind is populated from the response while
retaining resolvedKind as the fallback.

Reject surplus arguments and unknown flags.
workspace open, workspace close, and terminal close accept extra positional arguments. They also ignore unknown flags. A malformed destructive command can run instead of returning usage. Require exact positional counts and reject flags other than the supported options.

random_hex returns a predictable identity when getrandom::fill fails.
let _ = getrandom::fill(&mut buffer) discards the error. On failure the buffer stays all zeros, so random_hex returns a fixed string. Both new call sites use the result as an identity: the relay transport id in session.rs Line 610 and the tunnel pty_id in tunnel_terminal.rs Line 454. Two transports that both receive the zero value share one identity, and transport_owns then grants each transport access to the other's attachments.
Return a Result, or fail closed on error.

Store authorization and reply sinks per transport. handle_frame overwrites the shared Inner::auth before transport checks. emit_output, emit_exit, and authorize then use that snapshot for every attachment. Managed mode shares one PtyManager between the relay socket and tunnel listener. A frame from either transport can therefore replace the other transport's sink and authorization context. This can misroute output or exit frames and can close a tunnel attachment when the snapshot contains the relay's observe owner identity. Resolve the snapshot and sink from the attachment's owning transport_id.

Actually exclude dangling terminals from the snapshot.
The new loop only logs the missing host. It does not skip its terminal_id. If topology.tabs still references that terminal, terminal_order retains it and Lines 682-684 fail the whole snapshot with terminal ... references missing ....
Build a set of dangling terminal IDs here. Remove those IDs from terminal_order before the terminal projection loop.

Localize all VM error responses.
These API and socket paths return hardcoded English copy. Use the request locale for web responses, pass localized strings into the shared resolver, and add entries for every supported locale. Localize the Swift socket message with String(localized:defaultValue:). This also applies to web/app/api/vm/route.ts, which calls reportVmImageConfigError.

Synchronize the new image policy with the operational instructions.
The changed policy adds Daytona and Blaxel image selectors. It also states that defaultForKind can supply an image in deployed runtimes. However, Lines 215-218 and Lines 108-110 still document deployment and rollback only for E2B and Freestyle. Lines 101-104 also state that deployed creates fail when the selected image environment variable is missing. Update these sections to list DAYTONA_SANDBOX_SNAPSHOT, BLAXEL_SANDBOX_IMAGE, and BLAXEL_SANDBOX_DESKTOP_IMAGE, and clarify whether the deployed defaultForKind fallback is valid. Otherwise, operators can fail to configure or roll back the new provider and machine kinds.

OpenTelemetry JavaScript API 1.9 setGlobalTracerProvider setGlobalContextManager global registration duplicate disable documentation
💡 Result:
In OpenTelemetry JavaScript, the "Attempted duplicate registration of API" error occurs because the library enforces that global components—such as the TracerProvider, ContextManager, and Propagator—are registered only once per environment [1][2][3]. This design prevents conflicts in applications where multiple instances of the OpenTelemetry API might exist due to complex dependency trees or redundant initialization [4][5]. The registration logic is managed internally by the @opentelemetry/api package [1][3]. While there is no public-facing "disable" configuration flag to simply ignore these warnings or allow multiple registrations [1][3], you can address the error using the following approaches: 1. Identification and Removal of Redundant Code: The most common cause is multiple calls to initialization methods (e.g., calling register on an SDK, or explicitly calling setGlobalTracerProvider multiple times) [2][6][7]. Ensure that your application initialization logic only executes once [2]. Check if multiple libraries or automated instrumentation setups (such as those provided by Kubernetes operators or environment variables) are attempting to register the API simultaneously [2]. 2. Understanding the API Global Object: OpenTelemetry uses a global variable (specifically, a symbol key on the globalThis object) to store the API instance [4][1][3]. If you are working in an environment where you must re-initialize (e.g., during tests or hot-module reloading), you may need to clear the existing global registration. However, there is no official, supported function in the public API to "unregister" these globals [8][9][10]. 3. Troubleshooting: If you are encountering this error, examine the stack trace provided in the error message [2][6]. It typically points to the specific line of code performing the secondary registration. If the error stems from multiple versions of the @opentelemetry/api package being loaded (which can happen if different dependencies use incompatible versions), ensure your project's dependency tree is flattened so only one version of the API package is present [4][5]. While OpenTelemetry provides a DiagAPI to log diagnostic information, it does not currently provide a mechanism to suppress the "duplicate registration" error, as it is considered a significant configuration issue rather than a standard log message [1][10][3].

site:open-telemetry.github.io/opentelemetry-js @opentelemetry/api TraceAPI disable ContextAPI disable unregisterGlobal
💡 Result:
In the OpenTelemetry JavaScript API, there is no single "unregisterGlobal" function; instead, the API provides disable methods on individual namespaces to remove global configurations [1][2][3]. To effectively disable or reset specific global components, you can use the following methods: - Context API: Use api.context.disable to disable and remove the global context manager [1][4]. - Trace API: Use api.trace.disable to remove the global tracer provider [3]. - Metrics API: Use api.metrics.disable to remove the global meter provider [2]. Additionally, if you need to disable the entire SDK, the recommended approach is to set the environment variable OTEL_SDK_DISABLED=true [5][6]. Note that OpenTelemetry stores the global API on the global object to manage compatibility across different versions or multiple instances of the API package [7]. If you are attempting to prevent instrumentation entirely, setting the environment variable is generally the preferred, standard mechanism [5][6].

Isolate OpenTelemetry globals per test.
OpenTelemetry permits only one global tracer provider and context manager. These registrations occur during describe evaluation and remain active until afterAll, so a prior test can make this suite use the wrong provider or context manager. Move setup to beforeEach, then shut down the provider and disable both globals in afterEach.

Guard the fleet-fetch Task against the workspace being closed before it resumes.
The Task { @mainactor [weak self] in ... } started here awaits Self.cloudVMFleetPage() (a network call) before deciding whether to present NewMachineSheetPresenter or call launchCloudVMBaseOpen. Nothing checks that workspace (the placeholder tab created just above) is still open in tabManager.tabs when the await resumes.
If the user closes the placeholder Cloud VM workspace while the fetch is in flight, this Task still runs to completion. It can then present a "New Machine" sheet for a workspace the user already dismissed, or call launchCloudVMBaseOpen, which unconditionally starts CloudVMActionLauncher.shared.start(...) (the cmux vm base open CLI) regardless of whether the loading panel still exists. Per this function's own comment, the first Base open is a real provisioning choice, so an unguarded continuation after cancellation can provision cloud infrastructure the user no longer wants.
Add an early-return guard, consistent with the liveness checks already used elsewhere in this file (for example cleanupEmptySourceWorkspaceAfterSurfaceMove):
🐛 Proposed fix
Task { `@MainActor` [weak self] in
guard let self else { return }
let page = await Self.cloudVMFleetPage()
+ guard tabManager.tabs.contains(where: { $0.id == workspace.id }) else {
+ // The placeholder workspace was closed while the fleet
+ // fetch was in flight; don't provision or present a
+ // sheet for a workspace that no longer exists.
+ return
+ }
if page?.vms.contains(where: { $0.base != nil }) != false {Based on learnings from the coding guidelines: "Do not create fire-and-forget Task { ... } work with meaningful lifecycle unless it is stored, cancellable, or tied to a caller-owned operation."

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
launchCloudVMBaseOpen's doc comment promises onCompletion on failure, but the immediate-start-failure path does not call it.
The new doc comment says: "Failures land in the loading panel and in onCompletion." The implementation only honors half of that: when CloudVMActionLauncher.shared.start(...) returns didStart == false, the function calls loadingPanel.showFailure(...) but never invokes the onCompletion parameter. onCompletion is only invoked from inside the launcher's own completion closure, which fires only if the launcher actually started.
This affects both call sites that pass a real onCompletion: the direct retry at line 8564-8570, and the sheet's launch closure (around line 8540-8553), where the caller's completion/onCompletion never fires if the CLI process fails to start at all. A caller relying on that callback (for example ConfiguredGroupActionAsyncWorkspaceObserver.finishPending, reached through onCloudVMCompletion) never learns of this failure path.
🐛 Proposed fix
if !didStart, let loadingPanel = workspace.panels.values.first(where: { $0.panelType == .cloudVMLoading }) as? CloudVMLoadingPanel {
loadingPanel.showFailure(String(
localized: "panel.cloudVM.loading.failed.launch",
defaultValue: "Cloud VM command could not be launched."
))
+ onCompletion?(CloudVMActionLauncher.Completion(terminationStatus: 1, output: "", workspaceId: nil))

Chain the existing completion handler.
This assignment replaces the handler that Sources/AppDelegate.swift installs for Base setup cancellation. Cancelling the sheet then dismisses only the window. It does not close the placeholder workspace or report the cancelled completion.
