Fixes ctrl+4 not focusing the Cloud tab, and makes the right sidebar's tabs user-customizable.

Positional digit shortcuts (the bug fix). The ctrl+1…9 mode shortcuts now default to each tab's position among the visible tabs instead of a fixed table. With Feed and Dock feature-gated off (the default), the bar shows Files, Find, Vault, Cloud, but Cloud was pinned to ctrl+6 while ctrl+4 fell on the invisible Feed and did nothing. Now the 4th visible tab answers ctrl+4, whatever it is. Explicit user bindings still win; hint pills and the Settings shortcut list show the resolved values. CmuxSettings gains a host-installed default-stroke override (ShortcutDefaultOverrides) so the package's effective-shortcut resolution (Settings UI) agrees with the app's runtime defaults; without a host provider the package's static table answers unchanged.

Customizable tabs. New Settings > Sidebar card Right Sidebar Tabs: per-tab visibility toggles, reorder arrows, live shortcut labels. Right-clicking the mode bar shows the same show/hide toggles plus Customize Tabs…. Preferences persist in rightSidebar.tabs.order / rightSidebar.tabs.hidden. Hiding the last visible tab is refused. Explicit selection of a hidden tab (CLI right-sidebar, command palette, notification routing) still works and reveals the tab while active; session restore and preference changes re-land on a visible tab. Digit defaults follow reorders live (tab preference mutations post the shortcut-settings change notification, so matchers, hints, menus, and the Settings card all refresh).

Regression test commits: commit 1 adds the failing test only (testModeShortcutDigitsFollowVisibleTabPositions), commit 2 the fix, so CI goes red then green.

Also fixes a pre-existing red package test on main: setting:betaFeatures:cloudMachines was missing from SettingsRowAnchorResolutionTests' reachability mirror list (from #10478 settings row).

Localization audit: new strings rightSidebar.tabs.customize, settings.sidebar.rightTabs(+.subtitle, .moveUp, .moveDown) added to Resources/Localizable.xcstrings in en and ja; web/messages/{en,ja}.json docs.configuration.shortcutsWhenExample updated to stop naming Ctrl+1–5 as the sidebar's fixed range.

Summary by cubic

Fixes right-sidebar ctrl+digit shortcuts so they follow the visible tab order — Cloud previously answered only ctrl+6 while ctrl+4 hit the feature-gated Feed — and adds Settings, context-menu, and drag-to-reorder controls to show/hide and reorder the tabs. Explicit user bindings still win.

New Features

  • Tab preferences persist in rightSidebar.tabs.order / rightSidebar.tabs.hidden; hiding the last visible tab is refused, hidden tabs keep their slot, and dragging a mode-bar pill reorders the visible tabs in place via an in-process custom UTI declared in Info.plist.
  • Explicit selection of a hidden tab (CLI, palette, notification routing) still works and reveals it while active; restore and preference changes re-land on a visible tab.
  • CmuxSettings gains a value-typed ShortcutDefaultResolver injected per settings window, so its shortcut resolution and hints match the app's positional defaults without shared mutable state.

Bug Fixes

  • Rebuilds shortcut matcher snapshots after wiring the host resolver and on gate/preference changes so the positional shortcuts resolve from the first run.
  • Adds the missing setting:betaFeatures:cloudMachines search anchor to fix a pre-existing red package test on main.

Written for commit 51c6e63. Summary will update on new commits.

Summary by CodeRabbit

  • New Features
    • Customize right-sidebar tabs from Settings or the sidebar context menu.
    • Show, hide, reorder, and reset sidebar tabs with live updates.
    • Sidebar keyboard shortcuts now follow visible tab order.
    • Added localized English and Japanese labels and settings search support.
  • Bug Fixes
    • Prevented hidden or unavailable sidebar tabs from reappearing unexpectedly.
    • Ensured shortcut defaults correctly reflect feature availability and custom tab settings.

Inline drag reorder (added in a later round). Mode-bar pills are draggable: dragging one across its siblings reorders the tabs in place. The drag payload is an in-process custom UTI (com.cmux.right-sidebar-mode-reorder, declared in Resources/Info.plist), and each hover step commits through RightSidebarTabPreferences.setDisplayedOrder, which permutes only the displayed tabs' slots so hidden tabs keep their place. The ctrl+digit defaults shift live with the drag. Reorder math and slot preservation are unit-tested (RightSidebarTabCustomizationTests).

📝 Walkthrough

Walkthrough

The PR adds persisted right-sidebar tab ordering and visibility, positional Ctrl+digit shortcuts, settings controls, drag reordering, live updates, and host-provided shortcut default resolution.

Changes

Right-sidebar customization

Layer / File(s) Summary
Tab preferences and visible-mode resolution
Sources/RightSidebarTabPreferences.swift, Sources/RightSidebarMode+Availability.swift, Sources/FileExplorerState.swift, cmuxTests/RightSidebarTabCustomizationTests.swift
Persists tab order and hidden tabs. Filters invalid entries. Prevents hiding the final visible tab. Updates mode restoration and validates positional digits.
Runtime sidebar and host actions
Sources/RightSidebarPanelView.swift, Sources/HostSettingsActions.swift, Resources/Info.plist
Adds context-menu customization, drag reordering, live preference updates, and host actions for listing and changing tabs.
Settings sidebar controls
Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Environment/SettingsHostActions.swift, Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Sections/SidebarSection.swift, Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Sections/SidebarSection+RightSidebarTabs.swift, Sources/SettingsNavigation.swift, Resources/Localizable.xcstrings
Adds the settings card, tab metadata, visibility toggles, reorder controls, live updates, localization, and settings search indexing.
Dynamic shortcut contract and resolution
Packages/macOS/CmuxSettings/Sources/CmuxSettings/Values/*, Sources/KeyboardShortcutSettings.swift, Sources/cmuxApp.swift, Sources/KeyboardShortcutSettings+PersistedShortcutPolicy.swift, Sources/KeyboardShortcutSettingsLookup.swift, cmuxTests/*, web/messages/*
Adds ShortcutDefaultResolver. Host defaults now take precedence over built-in defaults. Right-sidebar actions derive shortcuts from visible tab positions.
Settings shortcut propagation and validation
Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Environment/SettingsRuntime.swift, Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Scene/SettingsWindowScene.swift, Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Sections/*, Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Bindings/*, Sources/KeyboardShortcutSettingsObserver.swift, Packages/macOS/CmuxSettingsUI/Tests/*
Passes the resolver through settings runtime and shortcut models. Reloads cached shortcuts when feature-gate defaults change. Tests resolver isolation and explicit unbinding.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 51c6e

After changing sidebar tab order or visibility, the Settings shortcut list may temporarily continue showing outdated Ctrl+digit labels, which can confuse users about the active shortcuts. The PR remains mergeable with owner awareness or a follow-up to ensure the settings labels refresh reliably.

Full details: Description check

Explanation

The description provides a detailed summary of the bug fix, customization features, persistence behavior, testing coverage, localization, and implementation details. It lacks the template's explicit Testing, Demo Video, Review Trigger, and Checklist sections, but the required change and test information is substantially present.

Full details: Cmux Swift Actor Isolation

Explanation

PASS. The production changes do not introduce a prohibited actor-isolation mistake. ShortcutDefaultResolver is a value type with an @Sendable provider and Sendable payloads. RightSidebarTabSettingsItem is a pure Sendable value model without implicit MainActor isolation. The new pure sidebar helpers used from the resolver are explicitly nonisolated. UI state remains in @MainActor SwiftUI types, and the new notification stream forwards updates through Task { @mainactor in ... }. The SettingsHostActions protocol was already explicitly @MainActor, SettingsRuntime was already @unchecked Sendable, and MobileHostStatusObserverToken was pre-existing. No changed code adds an unsafely shared mutable Sendable reference or accesses a UI-bound store from a background context.

Full details: Cmux Swift Blocking Runtime

Explanation

PASS. The complete PR diff from merge-base 750354e to HEAD adds no semaphores, blocking waits, sleeps, delayed dispatch, timers, polling, main-queue sync, or manual locks in production Swift. The added for await loops consume AsyncStream signals, and the Task { @mainactor ... } bridge does not use timing-based synchronization. The only duration is withAnimation(.easeInOut(duration: 0.15)) for visible drag UI, which the rule allows.

Full details: Cmux Browser Automation Off-Main

Explanation

PASS: The PR diff from main to HEAD does not modify Sources/TerminalController.swift, ControlCommandExecutionPolicy.swift, or their policy tests. It also adds no changed path containing browser, socket, automation, or WebKit terms. Therefore, the PR introduces no browser socket command routing change, off-main WebKit/AppKit access, or new worker command that requires policy coverage.

Full details: Cmux Expensive Synchronous Load

Explanation

PASS. The PR adds no synchronous agent-history load. The inferred PR diff adds no RestorableAgentSessionIndex, SharedLiveAgentIndex, transcript, trajectory, JSONL, directory-scan, or large-file parsing call. The new main-actor settings and sidebar paths read bounded UserDefaults values, shortcut settings, and tab arrays. The existing RestorableAgentSessionIndex.load() fallback in Sources/DockSplitStore+ClosedItemHistory.swift is unchanged.

Full details: Cmux Cache Substitution Correctness

Explanation

No failure condition is introduced. The diff does not replace a fresh authoritative read with a cache in a persistence, history, undo, or snapshot path. Right-sidebar preference mutations read UserDefaults through orderedModes/hiddenModes before writing. SidebarSection seeds its UI state with a fresh hostActions.rightSidebarTabs() read and receives event-driven updates. The shortcut matcher is an existing snapshot cache, and this change adds reloads for both shortcut-setting and UserDefaults changes. The host resolver computes positional defaults from current tab preferences.

Full details: Cmux No Hacky Sleeps

Explanation

PASS: The pull request changes 29 Swift files plus localization, plist, and project metadata. The only non-Swift source files are web/messages/en.json and web/messages/ja.json, which change documentation text only. The added non-Swift diff contains no sleeps, timers, polling, delays, retries, or waits. Swift timing is outside this check's scope.

Full details: Cmux Algorithmic Complexity

Explanation

PASS. The changed production collection work is limited to the fixed RightSidebarMode enum: six customizable modes plus the excluded customSidebar case. RightSidebarTabPreferences.orderedModes and setDisplayedOrder can be quadratic in that mode count, and the Settings row view performs per-row scans, but these collections are explicitly bounded at seven elements. The sidebar and shortcut paths therefore do not scan workspaces, sessions, files, or other scalable user-owned records. No new unbounded sort/filter loop, batch rescan, persistence join, or slower algorithm for ~1000 records appears in the diff.

Full details: Cmux Swift Concurrency

Explanation

The diff adds a new app-state Combine pipeline in Sources/RightSidebarPanelView.swift:256: .onReceive(NotificationCenter.default.publisher(for: RightSidebarTabPreferences.didChangeNotification)). This publisher/subscriber observes a cmux-owned preference notification and is not required by an external callback boundary. Async notification observation is already used in Sources/WorkspaceContentView.swift with NotificationCenter.default.notifications(named:). Other new async code is lifecycle-tied: the rightSidebarTabsUpdates() drain task is cancelled from AsyncStream termination, and the drag provider completion is an AppKit boundary. No new background DispatchQueue usage was found.

Resolution

Replace the new .onReceive publisher with a Swift concurrency observation tied to the view lifecycle, such as a .task that iterates NotificationCenter.default.notifications(named: RightSidebarTabPreferences.didChangeNotification) and calls refreshModeAvailabilityAndFocusIfNeeded() for each notification. Keep the task cancellable through the SwiftUI .task modifier.

Full details: Cmux Swift `@Concurrent`

Explanation

PASS: The PR adds no unisolated async production helper. The new SidebarSection stream consumer is @MainActor UI-bound work, and the host stream’s Task explicitly uses @MainActor. New visibleModes, positionalDigit, and preference helpers are synchronous nonisolated functions, which the rule allows. Existing network/file-related async methods were not changed in isolation, cost, or call sites.

Full details: Cmux Swift Package Boundaries

Explanation

The PR adds independently testable right-sidebar domain logic to the app target. Sources/RightSidebarTabPreferences.swift is Foundation-only preference, ordering, visibility, reset, and slot-preserving reorder logic. Sources/RightSidebarMode+Availability.swift adds visible-tab and positional-digit policy. Sources/RightSidebarPanelView.swift adds the UI-free RightSidebarModeBarReorderPolicy. The new cmuxTests/RightSidebarTabCustomizationTests.swift directly tests these policies, while the Xcode project places RightSidebarTabPreferences.swift in the app Sources build phase and the tests in the app test target. The logic is also consumed by the panel, shortcut settings, file-explorer restore, settings host actions, and app composition. This matches the rule's app-root domain-logic failure condition. The ShortcutDefaultResolver changes are correctly placed in CmuxSettings, but they do not move the new sidebar domain logic behind a package boundary.

Resolution

Create a small Packages/macOS/CmuxRightSidebar SwiftPM package with a CmuxRightSidebar target and package tests. Expose RightSidebarTabPreferences first, using injected canonical/available tab IDs, UserDefaults, and change signaling. Move the order normalization, hidden-tab protection, displayed-slot permutation, visible-tab selection, positional-digit policy, and RightSidebarModeBarReorderPolicy into that package. Keep AppKit, SwiftUI, localization, shortcut-action mapping, drag payloads, feature-gate adapters, notification bridging, and app lifecycle composition in the app target.

Full details: Cmux Swiftpm Lockfiles

Explanation

PASS. The PR diff has no Package.swift, package-local Package.resolved, .gitignore, or workflow changes. The only Xcode project change registers RightSidebarTabPreferences.swift and RightSidebarTabCustomizationTests.swift as source files; it does not add, remove, or modify any XCRemoteSwiftPackageReference or XCLocalSwiftPackageReference. The root Xcode lockfile exists and is unchanged. Therefore, no SwiftPM dependency or Xcode package-reference change requires a lockfile diff.

Full details: Cmux Swift Logging

Explanation

PASS. The full diff from the PR base adds no print, debugPrint, dump, NSLog, ad hoc file/stdout logging, or new Logger declaration. The existing hostSettingsLogger and its warning call in Sources/HostSettingsActions.swift are unchanged. The existing NSLog in Sources/cmuxApp.swift is also unchanged; the PR only moves shortcut-default wiring around it.

Full details: Cmux User-Facing Error Privacy

Explanation

PASS — The full PR diff adds sidebar settings labels, shortcut descriptions, accessibility labels, and tab menu text only. These strings use cmux/product terms and contain no upstream vendor names, provider-specific details, raw errors, identifiers, credentials, tokens, headers, or payload dumps. The new error-related material is limited to developer comments, tests, return values, and internal notifications; no user-facing error, alert, command output, API error body, or recovery copy violates the rule.

Full details: Cmux Full Internationalization

Explanation

The diff introduces incomplete localization. Resources/Localizable.xcstrings adds five user-facing keys (rightSidebar.tabs.customize, settings.sidebar.rightTabs, .subtitle, .moveUp, .moveDown) with only en and ja, while the touched catalog already contains 20 locale codes, including ar, bs, da, de, es, fr, it, km, ko, nb, pl, pt-BR, ru, th, tr, uk, zh-Hans, and zh-Hant. The changed docs.configuration.shortcutsWhenExample web message is updated only in web/messages/en.json and web/messages/ja.json; the same key remains with the old Ctrl+1–5 copy in the other routed locale files. The new UTTypeDescription value cmux Right Sidebar Tab Reorder in Resources/Info.plist also has no corresponding localized entry in Resources/InfoPlist.xcstrings. The new Swift UI call sites use localized APIs, but the required catalog and locale coverage is incomplete.

Resolution

Add translated string-catalog values for all 20 existing locales for each of the five new Localizable.xcstrings keys. Update docs.configuration.shortcutsWhenExample consistently in every locale listed by web/i18n/routing.ts and keep each corresponding web/messages/*.json entry locale-specific. Add localized Info.plist metadata entries for cmux Right Sidebar Tab Reorder in every locale supported by Resources/InfoPlist.xcstrings, using the catalog’s supported locale codes.

Full details: Cmux Swiftui State Layout

Explanation

PASS. The PR adds value-typed @State for rightSidebarTabs and draggingModeBarMode; it does not add ObservableObject, @Published, @StateObject, @EnvironmentObject, @Bindable, or GeometryReader measurement. The new ForEach renders RightSidebarTabSettingsItem snapshots, and its state writes occur in lifecycle, button, toggle, drag, or notification callbacks rather than during body evaluation. FileExplorerState retains existing legacy ObservableObject/@Published state and was touched incidentally. SettingsCard uses an eager VStack, not a lazy container, and the host action reference is a callback dependency, not an observable state store.

Full details: Cmux Architecture Rethink

Explanation

The PR adds a notification-based synchronization layer instead of one owner for right-sidebar state. KeyboardShortcutSettingsObserver now listens to the global UserDefaults.didChangeNotification and schedules matcher rebuilds. RightSidebarTabPreferences.notifyChanged() also posts KeyboardShortcutSettings.didChangeNotification as a cross-subsystem invalidation side channel. Separately, RightSidebarPanelView receives the tab notification, while HostSettingsActions.rightSidebarTabsUpdates() installs two notification observers and updates SidebarSection's @State snapshot through an AsyncStream. These changes are production synchronization paths, not test-only coordination or a required platform bridge. The matcher cache, panel-derived modes, and settings snapshot can therefore be temporarily stale relative to the UserDefaults source, and unrelated defaults writes also rebuild the shortcut cache. The changed code leaves that stale-state class representable while patching the reported shortcut symptom. The new value-typed ShortcutDefaultResolver and the single mutation methods are sound, but they do not remove this notification topology.

Resolution

Create one @MainActor-owned right-sidebar state store/coordinator that owns order, hidden tabs, feature availability, and the derived positional shortcut defaults. Make the mode bar and Settings section consume the same immutable value snapshot and action closures, or a typed state stream exposed by that owner. Move UserDefaults reads and writes behind the store. Make the shortcut matcher rebuild from that store's typed state/revision, and remove the global UserDefaults observer, the synthetic KeyboardShortcutSettings.didChangeNotification cross-post, and the per-view NotificationCenter observers. Use the same store stream for Settings updates. The first migration cut should prove that one snapshot derives both visible tabs and Ctrl+digit defaults, so no hidden or reordered state can exist in one consumer while another consumer still uses the old value.

Full details: Cmux Swift Auxiliary Window Close Shortcuts

Explanation

PASS. The PR adds or changes sidebar views, settings data flow, shortcut resolution, and drag payload handling. The diff does not add or materially change an NSWindow, NSPanel, NSWindowController, SwiftUI Window, or WindowGroup. The existing Settings window remains identified as cmux.settings and registered in cmuxAuxiliaryWindowIdentifiers. scripts/lint_auxiliary_window_close_shortcuts.py passes.

Full details: Cmux Source Artifacts

Explanation

PASS — The PR adds and modifies only Swift source, tests, project configuration, the product Info.plist, localization catalogs, and web localization files. The four added files are source or test files. No changed path matches the rule's scratch, cache, build, log, screenshot, recording, dependency-checkout, or artifact-directory patterns. The Info.plist UTI and Xcode project entries support the product's drag-reorder feature, and the localization changes are explicitly allowed. All changes are text files with no binary artifact additions.

Full details: Cmux No Test Or Debug Seam In Production Source

Explanation

PASS. The production Swift diff adds no new #if DEBUG or test-build guard, and no member with the rule's test/debug seam names. The widened SidebarSection.hostActions member supports the production SidebarSection+RightSidebarTabs extension; it is not a test wrapper. New helpers such as RightSidebarModeBarReorderPolicy, rightSidebarPositionalDefaultShortcut, and ShortcutDefaultResolver have production callers. Existing resetForTesting and rightSidebarDebugResponder members are unchanged from the merge base.

Full details: Cmux No Ambient Global State

Explanation

The PR adds static-only namespace types in production Swift. Sources/RightSidebarTabPreferences.swift:8-108 defines a caseless enum whose static methods read and mutate UserDefaults.standard and post notifications. Sources/RightSidebarPanelView.swift:650-666 adds RightSidebarModeDragPayload as a caseless enum containing only static constants and a factory, and lines 670-689 add RightSidebarModeBarReorderPolicy as a caseless enum containing only a static helper. These are new ambient static namespaces introduced by the PR. ShortcutDefaultResolver.builtIn is a static constant, and no new shared/standard/default singleton or top-level mutable variable was found.

Resolution

Replace RightSidebarTabPreferences with a constructable type that stores an injected UserDefaults (and, if needed, an injected notification center), and use one instance created at the app composition root. Inject that instance into HostSettingsActions, RightSidebarPanelView, and the shortcut-default resolver path so tab state has scoped ownership. Move drag-provider behavior onto an owning RightSidebarMode instance method or a private file-scope helper, with the UTI as a private constant. Replace RightSidebarModeBarReorderPolicy with a private/fileprivate pure file-scope helper or an injectable owning type. Remove the caseless static-helper namespaces.

Replace the process-wide override provider with an injected resolver.

Provider, _provider, and install(_:) create mutable global shortcut-resolution state. The settings package now depends on implicit installation order and a manual lock.

Pass the resolver through a constructable settings or shortcut-resolution owner instead. Keep the right-sidebar preferences as the single owner of this state.

As per coding guidelines: “Do not introduce a mutable flag, cache, singleton, observer, or side channel” and flag NSLock unless the change documents why an actor or MainActor owner cannot synchronize the state.

Route Cloud availability through CloudMachinesFeature.

featureAvailableModes duplicates the Cloud gate, while RightSidebarMode.visibleModes(defaults:), shortcut defaults, and restoration use CloudMachinesFeature.offMainIsEnabled(defaults:). The current inputs match, but separate sources can drift and make the mode bar expose .machines while shortcuts or restoration reject it. Use the shared resolver for every Cloud availability check.

Replace the static preference namespace with an injectable owner.

RightSidebarTabPreferences is a namespace-only runtime API for persisted state and notifications. Create a constructable preference store with injected persistence and notification dependencies. Pass that owner to the sidebar, shortcut resolver, and settings bridge.

As per coding guidelines, “Avoid new ambient global runtime state: top-level API functions, mutable globals, namespace-only types, and runtime singletons. Prefer constructable injectable owners and private/fileprivate helpers.”

Bugbot is paused — on-demand spend limit reached

Bugbot uses usage-based billing for this team and has hit its on-demand spend limit.

A team admin can raise the spend limit in the Cursor dashboard, or wait for the next billing cycle to continue.

With Feed and Dock feature-gated off, Cloud is the 4th visible tab in the
right sidebar's mode bar, but ctrl+4 was pinned to the invisible Feed and
did nothing while Cloud answered only ctrl+6. The new test presses ctrl+4
in that configuration and expects the Cloud (machines) tab.

Also pins the mode gates and tab preferences in the existing digit-default
tests so the test host's own settings cannot shift the expected digits.
The ctrl+digit mode shortcuts now default to the mode's position among
the VISIBLE tabs instead of a fixed per-mode table. With Feed and Dock
hidden, Cloud is the 4th tab and answers ctrl+4 (it was pinned to ctrl+6
while ctrl+4 fell on the invisible Feed and did nothing). Explicit user
bindings still win, hints and Settings show the resolved values, and
CmuxSettings gets a host-installed default-stroke override so the
package's effective-shortcut resolution agrees with the app.

Tabs are now user-customizable: a Right Sidebar Tabs card in Settings >
Sidebar (visibility toggles, reorder arrows, live shortcut labels) and a
right-click menu on the mode bar (show/hide plus a jump to that card).
Preferences live in rightSidebar.tabs.order / rightSidebar.tabs.hidden;
hiding the last visible tab is refused. Explicit selection of a hidden
tab (CLI, palette, notification routing) still works and reveals the tab
while it is active; restore and preference changes re-land on a visible
tab.

Also adds the missing setting:betaFeatures:cloudMachines anchor to the
package's reachability mirror list (pre-existing red test on main).
…e provider

The KeyboardShortcutSettingsObserver.shared @State stored property builds
its matcher snapshot before cmuxApp's init body runs, so the right-sidebar
digit entries were cached from the builtin table and ctrl+4 still fell on
the invisible Feed. Posting the standard shortcut-settings change
notification after installing the provider rebuilds those snapshots
against the positional defaults.
Each pill is draggable (in-process custom UTI, declared in Info.plist like
the workspace-tab reorder type). Hovering another pill commits the new
order through RightSidebarTabPreferences.setDisplayedOrder, which permutes
only the displayed tabs' slots so hidden tabs keep their place, and the
existing change notification re-renders the bar and shifts the ctrl+digit
defaults with the tabs.

Deliver an initial tab snapshot after subscribing.

Line 41 reads tabs before this stream subscribes. The host stream only yields after a notification. If a tab change occurs between these operations, this card keeps stale order or visibility until another change occurs. Make rightSidebarTabsUpdates() install its observers and then yield a current snapshot, or provide an atomic snapshot-and-subscribe API.

Observe right-sidebar tab preference changes in ShortcutListModel.

ShortcutListStableLazyView resolves each row through model.effective(for:). The injected resolver reads RightSidebarMode.positionalDigit, which reads RightSidebarTabPreferences.orderKey and hiddenKey. Because the resolver is @ObservationIgnored, those changes do not invalidate the shortcut model, so mounted settings rows can retain stale ⌃1…⌃9 labels. Observe the authoritative tab-preference stream at the host boundary or inject an observable resolver snapshot. Add a regression test for reorder and visibility changes.

RightSidebarTabPreferences orderKey and hiddenKey invalidate effective(for:) and
refresh mounted shortcut rows; replace the `@ObservationIgnored` resolver
dependency with host-bound observation or an observable resolver snapshot while
preserving per-model defaults. Add regression coverage verifying reorder and
visibility changes update the ⌃1–⌃9 labels.

This looks to have landed through #11950, which carries the sidebar shortcut behavior and customization. I’m closing the older branch to keep the queue tidy. Thanks for the original work :)
