fix(ios): land the Mac-surface selection store state the UI already uses - #10296
azooz2003-bit wants to merge 1 commit into
Conversation
04ff18e shipped WorkspaceDetailView code driving store.selectedMacSurfaceID / selectMacSurface(_:), a private-across-files effectiveConnectionStatus read, and a TerminalPickerMenuActions preview call missing selectSimulatorStream, but the store state itself never landed, so CmuxMobileShellUI does not compile (hidden until #10287 and #10290 fixed the modules before it). Implements the state to the contract its own test (MobileShellCompositePreviewTests) already specifies: explicit selection independent of terminal selection, cleared on workspace switch. Verified locally: CmuxMobileShell (with tests) and CmuxMobileShellUI build for arm64-apple-ios18.0-simulator. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
📝 WalkthroughWalkthroughThe mobile shell now clears Mac-surface selection when the workspace changes. It exposes independent Mac-surface selection APIs. Related UI code adds simulator-stream picker support and module-level access to connection status. ChangesMac surface selection
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to Mac-surface selection can become stale when workspace membership or surfaces change, potentially directing UI actions to the wrong surface. Merge should wait for selection reconciliation or explicit owner acceptance of this bounded correctness risk. Possibly related PRs

Reconcile surface selection when workspace topology changes.
selectedMacSurfaceID is cleared only when selectedWorkspaceID changes. However, workspaces.didSet at Lines 381-385 does not reconcile selection, and selectedWorkspace falls back to workspaces.first at Lines 1469-1473. If the selected workspace is removed or its surfaces change while the stored workspace ID remains unchanged, the UI can apply the old surface ID to the fallback workspace.
Move this reconciliation into the workspace-topology update path. Clear or validate selectedMacSurfaceID against the resulting workspace, and update selectedWorkspaceID when the selected workspace no longer exists. As per path instructions, “maintain one authoritative structured identity source” and avoid stale values that can route UI actions to the wrong surface.
