dev stacks are tailnet-only, so freestyle can't call their forward-auth route. CMUX_VM_PUBLICATION_FORWARD_AUTH_ORIGIN lets an operator point the edge at a tunnel while browsers keep signing in on the auth origin. unset in prod, malformed fails closed.
hover share button and copy team link on cloud machine port rows. reuses the port's publication or creates one with the server default (team for team machines), waits until it's active and the link actually answers, then copies it. requests run as the machine's owning team.

-
Explanation
The title "cloud: share a port with your team from the sidebar" matches the main change: the PR adds a share button and a "Copy Share Link" menu item to Cloud machine port rows, backed by a share service that creates and waits for a team-scoped publication. The title is specific, concise, and states the user-visible behavior. It omits the readiness polling and clipboard protection, which is acceptable.
Full details: Description check
-
Explanation
The description follows the template's main sections (Summary, Testing, Changelog, Proof, Checklist). The Summary leads with the user-visible behavior and explains the share flow and row state. Testing separates live dev-backend checks from earlier local test runs and states that the current head's hosted CI was the execution gate. The Changelog entry is present. The Proof section links a video. Gaps: the Checklist is not addressed, the description does not say whether localization was audited beyond the verify-local run, and the Testing section mixes in unrelated stacked-branch content (the Cubic and Cursor summaries, the merged main-branch changes). Those are non-critical gaps, so the check still passes.
Full details: Cmux Cloud Persistent Session And Early Input
-
Explanation
The diff does not change Cloud terminal creation or persistent cmux-tui transport. The new network transport is a cookie-free HTTP HEAD readiness probe for port publications. The
runKeyedchange only adds the port-share action and usesfallbackToUnownedTask: false; existing terminal action wiring is unchanged. No new Ghostty runtime, PTY/shell readiness gate, input routing, event socket, snapshot, revision, auth, or lease behavior is introduced.
Full details: Cmux Browser Automation Off-Main
-
Explanation
The PR does not change browser socket automation routing.
Sources/TerminalController.swift,ControlCommandExecutionPolicy.swift, and policy tests are unchanged. The only browser-related diff iscmuxTests/BrowserReplRenderHostTests.swift, which remains@MainActorand changes a test window fixture; it adds nobrowser.*command, WebKit wait, worker-lane command, or routing policy. Therefore, the rule's failure conditions are not introduced.
Full details: Cmux Expensive Synchronous Load
-
Explanation
The diff does not add or move an expensive synchronous agent-history load. New Cloud port code uses asynchronous API and URLSession operations in
CloudPortShareService.swift:74-151. The@MainActorstore only updates an in-memory phase dictionary and schedules an async sleep (CloudPortShareStore.swift:6-63). The interactive share action awaits the service and performs no file, JSON, transcript, trajectory, directory, or per-record syscall load (CloudTreeNodeActions.swift:698-756).CloudSheetWindowchanges only AppKit sizing and frame handling. No changed production Swift addition referencesRestorableAgentSessionIndex,SharedLiveAgentIndex, agent-history files, or synchronous file parsing.
Full details: Cmux Cache Substitution Correctness
-
Explanation
PASS: The Swift and TypeScript changes do not replace an authoritative read in a persistence, history, undo, or snapshot path.
CloudPortShareStoreholds only transient, in-memory UI phases (CloudPortShareStore.swift:4-8, 31-38) and uses operation IDs to fence stale updates (:46-85).CloudSheetWindowstores temporary geometry for active sheet layout, not persisted state (CloudSheetWindow.swift:25, 52-60). The publication changes add scoped requests and configuration validation; no cache substitution is present.
Full details: Cmux No Hacky Sleeps
-
Explanation
PASS. The covered production changes add only forward-auth environment validation/selection and shell preference parsing. The diff introduces no
sleep, timers, polling, fixed delays, or wall-clock synchronization in TypeScript, JavaScript, or shell runtime code. The workflow change is explicitly out of scope, and the added TypeScript test has no timing scaffolding.
Full details: Cmux Algorithmic Complexity
-
Explanation
No changed production path matches the complexity failure rules.
CloudPortShareService.existingperforms one linearfirstlookup over one publication response, not a nested or per-target scan. Its polling loop uses a fixed ten-delay array.CloudPortShareStoreuses dictionary lookups keyed by machine and port. The remaining production changes do not add scalable collection rescans, batch rescans, or unbounded sorting/filtering in hot paths.
Full details: Cmux Swift Concurrency
-
Explanation
The diff does not introduce a prohibited concurrency pattern.
CloudPortShareStoreuses Observation, not Combine, and stores and cancels its phase-resetTask. The share operation runs through the existingCloudWorkspaceOperationController, which stores and cancels keyed tasks; the new fallback explicitly avoids an unowned task. The test task is controlled test synchronization. The newDispatchQueue.main.asynccalls inCloudSheetWindowdefer AppKit/SwiftUI layout work on the main queue, which is an allowed UI boundary.
Full details: Cmux Swift Package Boundaries
-
Explanation
The PR places the independently testable port-sharing domain in the existing
CmuxCloudSwiftPM target:CloudPortShareService,CloudPortShareStore, and scopedVMClientpublication APIs are underPackages/macOS/CmuxCloud/Sourcesand have focused package tests with injected fakes, delays, probes, and cancellation gates. The app-target changes only compose that API withVMClient.shared, lifecycle operation control, pasteboard access, localization, SwiftUI row controls, and AppKit sheet behavior. These are app-lifecycle and UI/AppKit glue allowed by the boundary rule.
Full details: Cmux Swiftpm Lockfiles
-
Explanation
The PR does not change a SwiftPM manifest, Package.resolved file, .gitignore, or Xcode project package reference. Packages/macOS/CmuxCloud/Package.swift and its Package.resolved are identical at base and head. The root cmux.xcodeproj project file and Xcode Package.resolved are also unchanged. The only workflow change updates backend migration fallback logic and does not alter dependency resolution.
Full details: Cmux Swift Logging
-
Explanation
The Swift diff adds no
print,debugPrint,dump,NSLog, ad hoc logging, orLoggerdeclarations. ExistingcmuxDebugLogcalls are unchanged and remain debug-guarded where applicable. No changed log exposes secrets or personal data.
Full details: Cmux User-Facing Error Privacy
-
Explanation
PASS. The new sidebar share action is a concrete end-user path, but its changed failure copy is generic: “The link is still being set up,” “The Cloud service couldn't create a link for this port,” and “Couldn't create link.” Auth failures use existing cmux sign-in guidance. The changed web environment-variable validation and forward-auth configuration are server/operator paths, not cmux end-user error surfaces. No changed user-facing text exposes vendor names, internal provider details, raw upstream messages, identifiers, credentials, tokens, headers, or payloads.
Full details: Cmux Swift Auxiliary Window Close Shortcuts
-
Explanation
PASS. The Swift diff adds no standalone auxiliary window.
CloudSheetWindowand the three presenters only create or retain sheet windows, which the rule allows. The remaining AppKit window changes are test-only fixtures. The share-flow files add views, stores, and services without windows. The deterministicscripts/lint_auxiliary_window_close_shortcuts.pyalso passes and checks 42 identifiers.
Full details: Cmux Source Artifacts
-
Explanation
PASS. The authoritative diff contains only source files, tests, workflow/config files, the localization catalog, and an existing shell script. The three added files are Swift product/test sources. No changed path uses a forbidden scratch or artifact directory, and the diff contains no screenshots, recordings, logs, build output, caches, or dependency checkouts.
Full details: Cmux No Test Or Debug Seam In Production Source
-
Explanation
No prohibited production seam was added. The changed Swift production files contain no added DEBUG, TESTING, or XCTest build guards, and no member uses the prohibited debug/test names. CloudPortShareService injects API, delay, and probe dependencies for normal transport behavior; its configuration overload performs the real HEAD request and does not expose private state. CloudPortShareStore.phase(for:) is used by the production row UI, and the new share members have real production callers.
-
Full details: Cmux Swift Actor Isolation
-
Explanation
The production diff adds
CloudPortPublishingwith async requirements and nononisolatedannotation (CloudPortShareService.swift:5-8). It also adds the pureCloudPortShareErrorandCloudPortShareServiceSendable value types without explicit nonisolated isolation (:29-40). Under Swift 6 MainActor-by-default isolation, these declarations become MainActor-coupled even though the API is a background-capable service. The explicit@MainActoronCloudPortShareStoreand its MainActor call sites are appropriate and do not fail this check.Resolution
Mark
CloudPortPublishing,CloudPortShareError, andCloudPortShareServiceasnonisolated. KeepCloudPortShareStoreexplicitly@MainActor, and retain MainActor boundaries at its UI call sites.
Full details: Cmux Swift Blocking Runtime
-
Explanation
The PR adds production timing synchronization.
CloudPortShareServiceintroduces a readiness polling loop in a new shipped source file (shareUntilReady, lines 96-118) with ten fixed delays and a defaultTask.sleepat line 61;CloudTreeNodeActions.sharePortinvokes this service.CloudPortShareStorealso adds a production defaultTask.sleepat line 38 to expire UI phases. The repository rule treats polling loops and productionTask.sleepas failures, even when delays are injected for tests. The test-only injected sleeps do not change the production defaults.Resolution
Replace publication readiness polling and direct
Task.sleepwith a real readiness signal/state transition or an approved cancellation-aware async scheduler/sequence. Replace the store’s productionTask.sleepphase expiry with an approved UI completion or scheduler mechanism that does not useTask.sleepin production. Keep deterministic injected timing only in test code.
Full details: Cmux Swift `@Concurrent`
-
Explanation
The PR adds a network-heavy
CloudPortShareServicewith nonisolated async methods but no@concurrent.CloudTreeNodeActions.sharePortcallssharefrom the@MainActoroperation closure atSources/Cloud/CloudTreeNodeActions.swift:711-719. The service then performs publication requests, polling, and URLSession HEAD probes inCloudPortShareService.swift:73-155, so this work can remain on UI isolation under Swift 6NonisolatedNonsendingByDefault.CloudPortShareStoreis explicitly@MainActorand remains intentionally UI-bound; no issue was found there.Resolution
Add the established compiler-conditional
@concurrentboundary (@concurrentfor compiler >= 6.2, with the project’s compatible fallback where required) to the share service’s network async entry points and helpers, includingshare,existing,stopSharing, the polling/readiness helpers, and the signed-out URLSession probe. Ensure those functions access only Sendable state. Alternatively move the network work into a dedicated concurrent helper, then keep only clipboard and store updates on@MainActor.
Full details: Cmux Full Internationalization
-
Explanation
The PR adds production Cloud port-sharing UI text, and the Swift call sites correctly use localized APIs in
Sources/Cloud/CloudTreeNodeActions.swift:710-751,CloudTreeOutlineView.swift:932, andCloudTreeRowHoverButtons.swift:278-303. However, all 12 new keys inResources/Localizable.xcstringscontain translations only forar,de,en,es,fr,ja,ko,zh-Hans, andzh-Hant. The touched catalog already supportsbs,da,it,km,nb,pl,pt-BR,ru,th,tr, anduk, so the new entries are incomplete.Resolution
Add non-placeholder translated values for every new share-related key in
Resources/Localizable.xcstringsfor the missing locales:bs,da,it,km,nb,pl,pt-BR,ru,th,tr, anduk. Ensure all 12 keys have the complete catalog locale set.
Full details: Cmux Swiftui State Layout
-
Explanation
Cloud port rows add a store reference below the sidebar row boundary.
CloudPortShareButtonstoresCloudPortShareStoreatSources/Cloud/CloudTreeRowHoverButtons.swift:235and reads it duringbodyat line 239.CloudTreeCellViewhosts this view for eachNSOutlineViewrow at lines 211–214. The store is new@Observablestate, so the AppKit bridge does not own the observed state. This violates the rule requiring sidebar rows to use value snapshots and action closures, and can invalidate many rows when the shared dictionary changes. No newObservableObjectorGeometryReaderviolation is present.Resolution
Remove
storefromCloudPortShareButton. Pass an immutableCloudPortShareStore.Phase?snapshot and the required key/action closures into the row view. Update the snapshot at the AppKit row/coordinator boundary when the store changes, rather than observing the shared store inside each row. Keep share-operation mutations in action handlers and store lifecycle callbacks.
Full details: Cmux Architecture Rethink

Explanation
CloudSheetWindowadds a timing-based rendering repair path. It now defers frame restoration and anchor correction through severalDispatchQueue.main.asynccallbacks (lines 123-128, 150-154, 196-207, and 241-247), whileNSWindow.didMoveNotificationobservers and flags such asisHostMovePending,isAnchorCorrectionScheduled, andisApplyingFramecoordinate the same sheet geometry (lines 35-43 and 63-111). This patches 1×0 and host-move symptoms, but stale callback and notification ordering can still leave the sheet at the wrong size or top edge. The single source of truth should be one sheet geometry coordinator with explicit attachment, host-move, and resize transitions. The change materially expands the existing deferred-layout workaround into a multi-callback state machine, so it is not a small correctness fix or test-only synchronization.Resolution
Refactor
CloudSheetWindowso AppKit attachment, host movement, and content-size changes flow through one explicit geometry state machine and one lifecycle owner. Remove the delayed main-queue restoration and correction callbacks, and replace notification-driven pending flags with a single authoritative AppKit layout/frame transition. Keep presenters responsible only for retaining and dismissing the controller. Add tests for initial attachment, host movement, and content resize against that state machine.

the share button stays on cloud port rows at rest, uses the link symbol, and shows creating link / copied to clipboard beside it. the readiness check is now a signed-out POST on protected links only: cmux answers 401 without minting a sign-in transaction, and public links aren't probed since that would hit the user's app.
copy share link / share link instead of team wording, since a personal machine's link is owner-only; the note after copying still says who can open it. the inline note is fixed size so the controls host can't squeeze it to nothing.
…t in .env.example
- only reuse cmux-generated links; a custom domain on the port is left alone - poll by creating again (idempotent, resumes provisioning or unavailable rows, works on a teammate's row); 409 removing and 503 busy just mean not yet - probe accepts only 2xx/3xx or the forward-auth 401, total wait about a minute - don't overwrite the clipboard if it changed while the link was made; show link ready and copy on the next click - sidebar gets plain error copy instead of the cli wording from the server - store is @observable with an injected sleep for its auto-dismiss - note swaps without animation so it can't slide under the row - tests for the store and the new paths (12 pass)

Host-move handshake can stick
Medium Severity
applyPendingContentSize now waits on isHostMovePending, but that flag is cleared only after a successful record. The one-shot refresh does not retry when record bails on AppKit’s 1×0 frame, and a later sheet didMove that does clear the flag never applies the stored size. Content that arrives after open can stay unapplied for the life of the sheet.

Fixed in f7b26fe. The sheet didMove path now applies any pending content size when the host-move handshake completes, and anchor correction is deferred while the handshake is pending so a transient 1×0 move cannot restore a stale anchor.

Bound the layout poll by a deadline instead of an iteration count.
The for _ in 0..<100 loop waits in 10 ms run-loop turns, so its budget is about one second of wall-clock time. That budget does not grow with the time that a slow runner needs. A deadline bounds only the failure path. A passing run returns as soon as the content matches, and a slow runner has more time before the test fails.
Keep layoutSubtreeIfNeeded() and displayIfNeeded() inside the poll. They drive the attached sheet's layout.
Suggested fix

- for _ in 0..<100 { + let deadline = Date(timeIntervalSinceNow: 10) + while Date() < deadline { sheet.contentView?.layoutSubtreeIfNeeded() sheet.displayIfNeeded() let content = sheet.contentRect(forFrameRect: sheet.frame).size if abs(content.height - ceil(ideal.height)) <= 1, abs(content.width - ceil(ideal.width)) <= 1 { break } _ = RunLoop.main.run(mode: .default, before: Date(timeIntervalSinceNow: 0.01)) }

Inject CloudPortShareStore through the Cloud sidebar owner.
CloudPortShareStore.shared is new mutable runtime state. MachinesPanelView already creates CloudTreeNodeActions.bound(...) and passes the action bundle through CloudTreeOutlineView and CloudTreeCellView to CloudTreeRowHoverButtons. Use that composition path to create one store, inject it into the bound action, and pass the same instance to CloudPortShareButton. Then remove shared.
This is required by the no-ambient-global-state rule. The current binding also prevents tests from substituting a store in the real action path.

Replace the Task.yield() loops with a deadline-bounded poll or a real completion signal.
waitUntil waits for at most 100 Task.yield() calls. Line 188 waits for 20 yields and then asserts that nothing changed. A yield waits for nothing. On an idle machine, 100 yields take microseconds. On a loaded CI runner, the reset task may not run in that budget, so a correct implementation can fail holdClears. In newerPhaseSurvives, the check can pass before the stale reset task has run, so the test can miss a regression.
Bound waitUntil by a clock deadline. This deadline limits only the failure path. For newerPhaseSurvives, make the injected sleep closure signal when it returns. Await that signal, then assert the phase.
Proposed fix for `waitUntil`
-
private func waitUntil(_ condition: @MainActor () -> Bool) async { - for _ in 0..<100 where !condition() { await Task.yield() } + let deadline = ContinuousClock.now + .seconds(10) + while !condition(), ContinuousClock.now < deadline { + try? await Task.sleep(for: .milliseconds(5)) + } }
As per coding guidelines: "A poll of a condition bounded by an iteration count of Task.yield() ... Bound the poll by a clock deadline, or await the real signal."
Also applies to: 204-206

Clear the host-move gate when the attached sheet remains 1×0.
When the host moves while the attached sheet has a 1×0 content size, recordAttachedSheetMoveIfHostMoveIsPending() returns without clearing isHostMovePending. The single deferred refresh then ends, and later content-size reports are discarded by applyPendingContentSize(). The sheet can remain collapsed until another qualifying sheet move occurs.
This is a local state-transition fix. The same CloudSheetWindow.beginSheet(on:) path is used by the network-policy, create-team, and new-machine presenters. Keep the existing measured top-edge anchor; do not replace it with host.contentLayoutRect. Add a test for the host-move, 1×0, and later content-size sequence.

Personal machines with nil ownerTeamID share through the selected team's request scope.
CloudTreeNodeActions passes provider.ownerTeamID as teamID. When that value is nil, CloudPortShareService passes nil as scopeTeamID to the publication list and create calls. VMClient.request then binds the request to the currently selected team. The publication requests therefore carry the selected team's scope, not the machine's personal scope. The publication route derives the account and billing scope from that requested team. The server response for a personal VM under the selected team is not established by the inspected code.
The request scope and the body policy fields are separate. Omitting access and team fields in the create body is intentional. The problem is only the request-scope fallback. Pass an explicit personal request scope when the owner team is nil. Add that scope support in VMClient.request first. Do not pass nil and assume it means personal.
Suggested fix
-
The correction belongs at the request boundary in
VMClient.request. It needs a personal request-scope value that the publication methods can pass. This fix cannot be written from the inspected source, because that value is not defined there. Add it, then pass it fromCloudPortShareService.sharewhenteamIDis nil.

Summary
cloud machine port rows get a link button (always visible) and a "Copy Share Link" menu item. clicking it gives you an https link to that port that only signed-in members of the machine's team can open (owner-only on a personal machine). signed out you get the cmux sign-in wall, signed in on another team you get "You don't have access".

"answers" is a cookie-free HEAD: cmux's forward-auth returns 401 for a protected link without minting a sign-in or reaching the machine. Public links accept ordinary app responses once the edge forwards; edge 5xx and unknown protected routes remain not ready. polling creates again (idempotent on the fixed hostname, resumes a provisioning or unavailable row, works on a teammate's row), treats 409 and 503 busy as "not yet", and gives up after about a minute with "The link is still being set up". it polls because the service has no push channel for readiness; delays and sleep are injected.scopeTeamID; share passes the machine's owning team, same asopenPort.CloudPortShareStore(@Observable) keys progress by machine + port. spinner and "Creating link…", then a checkmark and "Copied to clipboard" for 2s, tooltip says who can open it. if the clipboard changed while the link was being made it isn't overwritten: the row says "Link ready" and the next click copies.stacked on #17123 (web, optional

Overview
This diff is CI and release plumbing (no app/cloud UI changes in the patch shown).
Nightly notarization adds
Continue nightly notarization, which picks up recovery artifacts from Nightly macOS build, polls Apple from Linux, staples on macOS only after acceptance, then publishes DMGs/feeds/R2 and optionally generates Sparkle deltas afterward.Runner and quota hardening moves many trusted-token workflows off fixed
