Summary

  • keep the release push toggle optimistic while async unregister cleanup runs
  • share the binding with the DEBUG readiness surface
  • add an XCUITest regression for turning the phone toggle off during a pending mutation

Root cause

The release-only binding introduced in 24cb551 updated notificationsEnabled only after updatePhonePushEnabled awaited coordinator cleanup. SwiftUI immediately read the old true value and rendered the switch back on.

Verification

  • swiftc -parse passed for changed Swift files
  • tagged macOS cloud build ntoff passed
  • iOS package tests are unavailable locally because the package declares iOS-only dependencies
  • iOS Release archive lane is blocked by the fleet disk safety floor (11 GB free, 20 GB required)

Summary by cubic

Fixes the iOS Push Alerts toggle so it updates immediately and the latest intent wins. Previously the switch snapped back on and stale registration/unregistration could override newer choices; now we commit the preference up front, serialize and bound mutations, and persist opt‑out cleanup across restarts.

  • Coordinator: own a generation-ordered enabled intent via MobilePushCoordinator.setEnabledIntent(_:); keep the toggle interactive using MobilePushToggle; cancel stale workers; tie mutation lifetime to the view; bound OS authorization and session snapshots with push_registration_session and push_unregistration_session timeouts.
  • Service: extend PushRegistrationService with applyEnabledIntent(_:generation:) and reconcileEnabledIntent(generation:); persist opt-out before auth; queue offline deletes in a durable SQLite-backed store; drain/repair on app start; coalesce repeated intents; prevent late DELETEs from overriding newer enables; serialize retries after reconciliation; tolerate caller cancellation.
  • UI: remove the retired Toasts toggle and restore its binding where kept; initialize the Task Composer setting; add deterministic UITest coverage for immediate updates and “latest wins” with CMUX_UITEST_PUSH_PHONE_MUTATION_DELAY=1.

Migration

  • PushRegistering conformers must implement applyEnabledIntent(_:generation:) and reconcileEnabledIntent(generation:).
  • iOS callers should call MobilePushCoordinator.setEnabledIntent(_:); MobileSettingsView uses MobilePushToggle.

Written for commit 52e1b9c. Summary will update on new commits.

📝 Walkthrough

Walkthrough

The PR adds a reusable asynchronous phone push toggle, integrates it into mobile settings, removes the beta Toasts toggle, persists the task composer setting, and adds delayed mutation UI-test coverage.

Changes

Push toggle flow

Layer / File(s) Summary
Reusable async toggle
Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/MobilePushToggle.swift
Adds optimistic updates, rollback on failure, disabled interaction during updates, localized text, and accessibility configuration.
Settings integration
Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/MobilePushSettingsContent.swift, Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/MobileSettingsView.swift, Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/MobileDisplaySettings.swift
Routes phone notification controls through MobilePushToggle, tracks update progress, removes the beta Toasts toggle, and loads the persisted task composer setting.
Delayed mutation validation
Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/Debug/MobilePushReadinessPreviewView.swift, ios/cmuxUITests/PushReadinessUITests.swift
Adds an environment-controlled 2-second mutation delay and verifies the toggle changes off immediately, stays disabled while pending, then becomes enabled while remaining off.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Mergeability Score: ⚪ Minimal · up to 63ed2

The change makes the iOS push-alert toggle update immediately during asynchronous cleanup and adds focused regression coverage; no actionable merge-blocking risk remains beyond normal checks and review.

Check name Status Explanation
Linked Issues check ✅ Passed Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check ✅ Passed Check skipped because no linked issues were found for this pull request.
Cmux Swift Actor Isolation ✅ Passed The diff adds a SwiftUI-only MobilePushToggle; its async task and handlers use explicit @MainActor boundaries. MobileDisplaySettings was already @MainActor, and no new Sendable reference or service...
Cmux Swift Blocking Runtime ✅ Passed The only new timing primitive is Task.sleep in a #if os(iOS) && DEBUG XCUITest harness, enabled by a CMUX_UITEST flag; production toggle code adds no blocking synchronization.
Cmux Browser Automation Off-Main ✅ Passed The exact PR diff changes only iOS push settings/UI and XCUITests; it adds no browser.* socket command or changes to the specified macOS routing/policy files.
Cmux Expensive Synchronous Load ✅ Passed The PR diff adds only push-toggle state/binding, an async 2-second test delay, and a UserDefaults read; it adds no agent-history loader, file/JSON parse, directory scan, or per-record syscall.
Cmux Cache Substitution Correctness ✅ Passed The diff adds a UserDefaults initialization and changes transient push-toggle UI state; it does not replace a fresh read with a cache in persistence, history, undo, or snapshot paths.
Cmux No Hacky Sleeps ✅ Passed The PR-like diff changes only six Swift files. Its only added sleep is a DEBUG UI-test fixture delay, and the test uses XCTest expectations; the non-Swift runtime sleep rule does not apply.
Cmux Algorithmic Complexity ✅ Passed The PR adds only O(1) toggle state updates, rollback, and preference initialization; it introduces no scalable collection scans, sorting, joins, or batch rescans.
Cmux Swift @Concurrent ✅ Passed Changed async work is explicitly @MainActor UI coordination; the PR adds no nonisolated async or invalid @concurrent, and cleanup remains an awaited registration-service call.
Cmux Swift Package Boundaries ✅ Passed Changed production files are in the existing CmuxMobileShellUI SwiftPM target; MobilePushToggle is a small SwiftUI view, the fixture is DEBUG-only, and persistence changed by one initialization line.
Cmux Swiftpm Lockfiles ✅ Passed The PR range changes only Swift sources and UI tests; it includes no Package.swift, Package.resolved, .gitignore, workflow, or Xcode package-reference changes, so the lockfile policy is not triggered.
Cmux Swift Logging ✅ Passed The PR diff adds no print, debugPrint, dump, NSLog, Logger, or ad hoc file/stdout logging; its additions are state handling, a DEBUG fixture, and XCUITest code.
Cmux User-Facing Error Privacy ✅ Passed The diff adds a generic push-alert setting and a DEBUG test fixture; its environment variable and test messages are developer-only, with no prohibited detail in user-facing errors or recovery copy.
Cmux Full Internationalization ✅ Passed The toggle uses L10n.string with the existing mobile.notifications.phoneEnabled key; Localizable.xcstrings already has translated en and ja entries. Other added text is test or fixture content.
Cmux Swiftui State Layout ✅ Passed The PR adds a binding-based toggle and event-handler Task only; the diff adds no ObservableObject/@published, GeometryReader, lazy-row store reference, or render-time state mutation.
Cmux Architecture Rethink ✅ Passed The diff centralizes phone-toggle behavior in MobilePushToggle; its only Task.sleep is in the #if DEBUG XCUITest fixture, which the rule allows as test-only synchronization.
Cmux Swift Auxiliary Window Close Shortcuts ✅ Passed PR changes iOS views, toggle state, fixture delay, and XCUITest only; the diff adds no NSWindow, NSPanel, Window, WindowGroup, or close-shortcut routing.
Cmux Source Artifacts ✅ Passed The PR changes only intentional Swift source and XCUITest files; no logs, screenshots, caches, build output, scratch directories, or dependency artifacts appear in the diff.
Cmux No Test Or Debug Seam In Production Source ✅ Passed The new delay fixture is private and confined to the DEBUG-gated Debug/MobilePushReadinessPreviewView.swift; its only caller is a DEBUG-gated preview route. MobilePushToggle is ordinary product beh...
Cmux No Ambient Global State ✅ Passed The feature diff adds only the constructable MobilePushToggle view and scoped instance/@State changes; it adds no top-level API, mutable global, static-only namespace, or new singleton.
Title check ✅ Passed The title clearly and concisely describes the primary change to the iOS push alerts opt-out toggle.
Description check ✅ Passed The description explains the change, root cause, verification, test coverage, and known test limitations, although it omits template sections such as the demo video and checklist.

34-39: 🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

⚠️ Unverified finding
Sandbox verification was unavailable.

Move mutation lifecycle ownership out of the view task.

This untracked Task can outlive MobilePushToggle. Its isUpdating guard belongs to screen-local state in both callers. If Settings closes and reopens before onChange completes, a new control can start another mutation while the first mutation still runs.

Make the existing mutation owner serialize the operation and publish the pending snapshot. Have MobilePushToggle render that snapshot instead of owning an untracked operation.

As per 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. As per path instructions, the push-notification toggle must maintain one authoritative enabled-state source.
