Summary

When the sidebar is collapsed and the user clicks a project, the session list updated silently behind the hidden panel — no visual feedback, nothing appeared to happen. The user had to manually re-open the sidebar to see the result.

Selecting a project implies intent to browse its sessions. The sidebar should open automatically to reflect that.

Root Cause

Project selection is handled in two separate store actions:

• selectRepository — triggered by dashboard project cards
• selectProject — triggered by the command palette and keyboard shortcuts

Neither action accounted for the sidebar being collapsed when called.

Fix

Added sidebarCollapsed: false to the set() call in both selectProject and selectRepository. The change is atomic with the selection itself — the sidebar opens at exactly the same moment the session list updates.

// selectProject (projectSlice.ts)
set({
  selectedProjectId: id,
  sidebarCollapsed: false, // Ensure session list is visible when a project is selected
  ...getSessionResetState(),
});

// selectRepository (repositorySlice.ts)
set({
  selectedRepositoryId: repositoryId,
  selectedWorktreeId: worktreeToSelect.id,
  selectedProjectId: worktreeToSelect.id,
  activeProjectId: worktreeToSelect.id,
  sidebarCollapsed: false, // Ensure session list is visible when a project is selected
  ...getSessionResetState(),
});

Files Changed

Test Plan

• Collapse the sidebar (Cmd+B or the toggle button)
• Click any project from the dashboard — sidebar should open automatically
• Open the command palette (Cmd+K), select a project — sidebar should open automatically
• Selecting a session within an already-open sidebar is unaffected
