Suggested reviewers: Merge Risk: 🔵 Low · up to The PR adds a persistent right-sidebar titlebar control and related settings. The change is otherwise mergeable, but the UI test should explicitly enable the setting to avoid environment-dependent results, and the Danish documentation wording should be broadened to accurately describe the available sidebar settings.

In `@cmuxTests/RightSidebarChromeSettingsTests.swift`:
- Around line 32-56: Protect UserDefaults.standard mutations in the affected
settings tests by introducing and using one shared test-serialization gate
across RightSidebarChromeSettingsTests and TitlebarInteractiveControlTests.
Ensure the gate covers each test’s setup, assertions, and cleanup, rather than
relying only on the suite-level .serialized trait, so CmuxSettingsFileStore and
rightSidebar.showTitlebarToggle cannot be accessed concurrently.
In `@Sources/Update/UpdateTitlebarAccessory.swift`:
- Line 2688: Initialize lastShowsRightSidebarTitlebarToggle with
resolvedRightSidebarTitlebarToggle(defaults: .standard) during controller
initialization instead of the static default value, so runtime changes from
persisted false to true trigger attachToExistingWindows(). Add coverage for the
false-at-launch, true-at-runtime transition.
In `@web/messages/ar.json`:
- Line 1046: Update the description for the right-sidebar settings entry to use
broader Arabic wording that covers all right-sidebar chrome, including the
titlebar toggle, rather than referring only to the toolbar. Keep it aligned with
the rightSidebar schema contract.
In `@web/messages/km.json`:
- Line 1048: Update the showOpenAsPaneButton translation to use the catalog’s
established Khmer term បន្ទះ for “pane” instead of ផ្ទាំង, while preserving the
rest of the description.

Greptile SummaryThe PR adds a persistent, configurable right-sidebar titlebar toggle and reuses a mirrored sidebar glyph in the sidebar header. It also wires the two right-sidebar chrome preferences through the settings catalog, JSON parser/template/schema, documentation, localization files, project configuration, and focused tests. Confidence Score: 5/5The PR appears safe to merge, with no concrete blocking or independently actionable non-blocking defects identified. The new accessory remains scoped to validated main windows, runtime preference changes reconcile attachment and removal, and both configuration keys are consistently represented across storage, schema, documentation, localization, project wiring, and tests.

Review audit rechecked against HEAD
No Codex review body was returned. Vercel, CLA, and review-spend notices contain no distinct code-review request. The independent reviews' supported-static reactivity findings are addressed above; live tooltip/tint refresh remains unverified. The close-only accessibility label remains fixed by Verification at this HEAD: ten static checks and the file-length guard pass; neither Swift budget TSV changed. The native catalog validator reports nine catalogs/nine required locales with zero parity errors. All 20 web locales contain the three sidebar descriptions. The broader localization-helper backlog is disclosed in the PR rather than represented as clean. Current-head CI was re-triggered by the main merge; stale All stale Tagged verification is blocked before job creation because the existing task backend uses reserved port Scope tradeoffs: the new toggle defaults on for discoverability, while Open as Pane retains its old default and both have independent opt-outs. Mainline now owns the EventStream convention repair that was previously present in this branch; it is not part of the current PR diff. No production-backend or unscheduled-build fallback was used. This PR remains open and unmerged while current-head native/runtime verification is incomplete. — CobaltQuill10105 (registration pending) |

Closes #10105
Summary
toggleRightSidebarInActiveMainWindow(preferredWindow:)action, so the sidebar can be reopened after its in-panel control hides it.xmark.rightSidebar.showTitlebarToggleandrightSidebar.showOpenAsPaneButton, both defaulting totrue, to the typed settings catalog,cmux.jsonparser/template/schema, and localized configuration documentation.Root cause and layout correction
The only right-sidebar control belonged to
RightSidebarPanelView, so hiding that panel also hid the control. The titlebar manager previously attached only the left accessory.The persistent AppKit accessory also needs its own horizontal space: the app's SwiftUI content extends into the titlebar. A SwiftUI
zIndexcannot reorder an AppKit sibling. The panel header now reserves the same 30-point width that the accessory uses and releases it whenever the accessory is hidden (fullscreen, minimal presentation, or the configuration opt-out). The accessory container is sized before attachment so its hosted button has a hittable frame from the first layout.Verification
