Swiping back from a thread showed the tab bar and New chat button mid-gesture as an overlay on top of the card, which felt wrong next to native iOS. Waiting until the transition finished fixed the flash but made the dock land late.

Keep the floating dock on the root card so the interactive pop uncovers it underneath, the same way a native tab bar comes back.

Before / after

Before

Back swipe with mid-gesture dock flash

After

Back swipe revealing dock under the card

Created with Composer in Cursor.

Made with Cursor

The floating dock was an overlay toggled by lifecycle events, so it either
flashed mid-gesture or appeared late after settle. Keep it on the root card
so the interactive pop uncovers it like native navigation.

Approvability

Verdict: Would Approve

Macroscope's review found this PR approvable — The iOS workspace dock now sits on the root card so back swipes reveal it underneath the departing screen. Exposure is limited to navigation presentation; the reported duplicate dock on iPad Usage remains covered by the separate correctness gate.

Needs human approval because:

Walkthrough

The iOS workspace navigator selects whether workspace tabs appear in the native sidebar or in a dock. The dock renders as the root card’s footer. WorkspaceNativeTabs no longer renders the floating footer overlay.

Changes: Workspace tab footer placement

Layer / File(s) Summary
Root-card footer support
apps/mobile/src/native/createV5StackNavigator.ios.tsx
V5CardStackView accepts an optional rootFooter and renders it only on the root card.
Workspace footer placement
apps/mobile/src/features/layout/createWorkspaceStackNavigator.ios.tsx, apps/mobile/src/features/layout/workspace/WorkspaceNativeTabs.ios.tsx
WorkspaceStackView selects a card-stack dock based on tab and layout state. CardStackDock positions the sidebar tab footer and applies the described iPad width limit. WorkspaceNativeTabs no longer renders the floating footer overlay or accepts tabsInSidebarColumn.

On iPad Usage the card stack already owns the floating dock, and the leftover
NativeTabs overlay mounted a second copy on top of it.

Moving the floating dock off the NativeTabs overlay inverted the medium-layout
condition, so Duo Usage lost tab navigation. Match the old overlay: medium pages
keep CardStackDock; column tabs still use the sidebar toolbar.

Written by claude-opus-5-5 on behalf of Maria

Merged current main (merge commit, no rebase) to clear the conflict in WorkspaceNativeTabs.ios.tsx. On main, that conflict was only a hook refactor (panes moved to useWorkspacePaneState) inside the floating overlay that this PR deletes. I kept the PR's side, so the diff against main is unchanged in intent: the dock lives on the root card, and WorkspaceNativeTabs has no overlay.

Review findings: Macroscope's double-dock finding on iPad Usage, the one its approvability gate cites, was fixed in 365dc4b when the overlay was removed. CodeRabbit's medium-layout Usage finding was fixed in 7acc4e8. No code changes were needed beyond the merge.

vp run check:changed passes on the merge commit.

Moving the dock onto the root card covered it whenever JS columns kept the
sidebar beside a pushed detail. Overlay that path again; non-split stacks
still reveal the dock under an interactive back swipe.
