Problem

The unfolded iPhone Duo's portrait sidebar is too narrow for PR titles and labels. Give its shared PR/Threads overlay a 350pt width and keep the floating navigation actions left-aligned within their original 280pt width.

Change

Constrain the native column to the same width so UIKit cannot shrink it back. Both lists keep their existing two-line title limits and trailing ellipsis.

Scope and approval

This is one layout change for the unfolded iPhone Duo's native portrait overlay: a 350pt PR/Threads list with the floating navigation actions kept within their existing 280pt width. Landscape sizing, title line limits, navigation behavior, and other clients are unchanged. The PR author requested this change. No upstream maintainer approval or triaged issue is linked; upstream maintainer approval of the default layout change remains pending, as flagged by Macroscope.

Verification

vp run check:changed upstream/main passed format, lint, both knip passes, mobile/scripts typechecking, and 16 existing layout tests. The focused layout and reserved-region run passed all 23 tests.

Runtime check on an unfolded Duo simulator in portrait (669×951pt), using the same device, backend, and data for both builds: the baseline overlay renders at about 280pt, and this branch renders it at about 350pt, with the tab bar unchanged at its original width. Tapping the dimmed content still dismisses the overlay.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — The portrait Duo sidebar now defaults to 350 wide, with fixed overlay column sizing and a 280-wide tab bar. Human review is required to confirm this change to the default layout experience.

Walkthrough

The portrait native workspace layout now uses a 350-point list-pane width when a hinge is present, unless a division region supplies its position. iOS workspace columns and sidebar tabs use the layout state to constrain widths when the primary sidebar overlays content.

Changes: Workspace Overlay Sizing

Layer / File(s)	Summary
Derive portrait hinge width apps/mobile/src/lib/layout.ts	For a native workspace with a hinge in portrait, deriveLayout sets listPaneWidth to 350 unless a division region supplies its position. Other cases retain the existing clamped calculation.
Apply iOS width constraints apps/mobile/src/features/layout/createWorkspaceStackNavigator.ios.tsx, apps/mobile/src/features/workspace/WorkspaceSidebarTabs.ios.tsx	WorkspaceColumns uses the layout list-pane width for its primary column constraints. WorkspaceSidebarTabs sets the tab bar maximum width to 280 when the primary sidebar overlays content.

Full details: Description check

Explanation

The description includes the required Problem, Change, Scope and approval, and Verification sections. However, it states that maintainer approval is pending, while the template requires a linked issue or explicit approval. The verification also conflicts with the objectives: native verification was blocked, and the after images are AI design mockups rather than runtime screenshots.

Resolution

Link the triaged issue or maintainer approval discussion and include the explicit approval comment. Correct the verification section to state that native verification was blocked, replace mockups with runtime screenshots, and report any remaining verification limitations accurately.
