Problem

On an unfolded iPhone Duo held in portrait, the thread sidebar slides over the page. Opening a Settings page from it (Sidebar button → Settings tab → General, or Environments after adding one) closes the sidebar. The page is then left with no back button, no sidebar button and no tab bar, and the only way out is to rotate to landscape. Thread and pull request pages in the same layout keep their sidebar button.

Change

https://git.cafe/pingdotgg/t3code/pulls/24766 removed the sidebar button that the Settings page in the detail column used to get, which is right while the sidebar sits beside the page. ColumnScreen in createWorkspaceStackNavigator.ios.tsx now adds that button (useWorkspaceSidebarHeaderItem, the same item threads and pull requests use) to the Settings page again, only while the sidebar overlays the content (layout.primarySidebarOverlaysContent). With the sidebar beside the page, the header stays as https://git.cafe/pingdotgg/t3code/pulls/24766 left it. A page's own leading header items still win, and only the options change, so the native header is not remounted. Android has no overlay sidebar and is unchanged.

Scope and approval

Fixes #28447

Verification

  • vp run check:changed on the merged head passes: format, lint, knip, typecheck (2 packages), React compiler.
  • No unit test: the defect is a header item gated on the layout mode. A component test would only restate the prop wiring.
  • Reproduction attempt: I ran the dev client from this checkout on a pooled iPhone Duo simulator (iOS, unfolded, light mode, no environments) and followed the issue's steps. Every rotation (portrait, landscape-left, landscape-right, portrait-upside-down) left the window at 951×669 landscape, both folded and unfolded. Forcing the layout flag in JS does not help: on a hinge device UIKit picks overlay or tile from the real orientation. The changed path (overlay sidebar) only exists in real portrait, so I have no before/after captures.
  • cannot-verify ios-device: unfolded iPhone Duo in portrait. To check: Sidebar button → Settings → General, then press the sidebar button on General and confirm the Settings list slides back in. In landscape, confirm General still has no sidebar button.

On an unfolded iPhone Duo in portrait, the thread sidebar overlays the page
and closes as a Settings page opens, leaving that page with no back button,
no sidebar button and no tab bar. #24766 dropped the Settings page's sidebar
toggle to keep the beside-the-page header clean; restore it only while the
sidebar overlays content. A page's own left header items still win.

Walkthrough

The iOS workspace navigator can add a sidebar header item to settings screens when the primary sidebar overlays content. Existing custom header-left items take precedence.

Changes: Settings sidebar access

Layer / File(s) Summary
Add the sidebar item to settings
apps/mobile/src/features/layout/createWorkspaceStackNavigator.ios.tsx
ColumnScreen adds the sidebar header item when sidebarToggle is enabled and the slot options do not define unstable_headerLeftItems. The settings slot enables this option when the primary sidebar overlays content.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix · Severity of issue fixed: Medium

Suggested reviewers: t3dotgg, maria-rcks

Merge Risk: Low · up to eefa8

Settings users hear a misleading “thread sidebar” label in VoiceOver; replace it with a neutral sidebar label. The issue is localized and does not block navigation.

Full details: Description check

Explanation

The description includes the required Problem, Change, Scope and approval, and Verification sections. It explains the defect, implementation, scope, checks performed, reproduction attempt, and verification limitation. It does not include before-and-after screenshots because the overlay layout could not be reproduced, but it documents that limitation and provides manual verification steps.

Full details: Linked Issues check

Explanation

Issue #28447 requires a way back from Settings detail pages when the primary sidebar overlays content. The change passes sidebarToggle only for the Settings slot when layout.primarySidebarOverlaysContent is true. ColumnScreen then supplies useWorkspaceSidebarHeaderItem() through unstable_headerLeftItems. Existing leading items take precedence. The flag is absent when the sidebar tiles beside the page, and the change is limited to the iOS navigator. The PR reports that the changed-head format, lint, knip, typecheck, and React compiler checks pass.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff changes one iOS layout file. The added hook usage and conditional header option directly implement issue #28447. The precedence check preserves existing page header items, and the layout-mode gate preserves the landscape behavior requested by the issue. No unrelated product behavior or platform change is present.

Minor · Functional Correctness · Quick win

Use a Settings-specific sidebar label.

The shared hook labels this button “Show thread sidebar” or “Hide thread sidebar,” but it controls the Settings list here. This misleads VoiceOver users. Use a Settings-specific label or a neutral sidebar label. (raw.githubusercontent.com)

Thanks, @juliusmarminge, for fixing this. Main now covers the same escape route: #27086 (29db71bf25) gives Settings detail pages the shared sidebar toggle through their pane header, including the overlay layout. Closing this as already covered.
