Summary

  • keep collapsed folders closed when the Shell file tree refreshes after filesystem changes
  • discard stale expanded descendants beneath a collapsed ancestor before replaying tree state
  • replace the cramped Shell and chat working-directory warning with clearer copy and a responsive action card

Root cause

The tree persisted expansion state on a debounce. A filesystem refresh could reset the tree before the latest collapse snapshot was reported, and nested directory handles could still carry expanded state that reopened their parent.

The fix tracks the live model state synchronously, normalizes descendants beneath collapsed folders, and uses that snapshot during resetPaths.

Verification

  • Shell UI test suite: 34 files, 334 tests passed
  • Shell UI production build: TypeScript check and bundle passed
  • Harness Console: collapsing a folder followed by a real filesystem refresh leaves it collapsed
  • Harness Console: working-directory mismatch copy wraps cleanly and keeps Use for chat as a separate action at split-panel width
  • git diff --check

Summary by CodeRabbit

  • Improvements

    • File tree expansion state is now preserved more reliably when navigating, refreshing, or updating directory contents.
    • Collapsed folders remain collapsed while expanded folders continue to be restored appropriately.
    • Working-directory messages now use clearer, more consistent wording.
  • Style

    • Review messages now support inline actions with improved borders, hover and focus states, truncation, and responsive stacking on smaller screens.
  • Tests

    • Added coverage for directory expansion restoration and updated working-directory message expectations.

Review Change Stack

📝 Walkthrough

Walkthrough

Changes

The change centralizes expanded directory path tracking, updates working-directory message text, and adds responsive styling for review messages with inline actions.

Directory expansion state

Layer / File(s) Summary
Expanded directory path tracking
shell/ui/src/page/tree-expansion.ts, shell/ui/src/page/FilesTab.tsx, shell/ui/src/page/__tests__/tree-expansion.test.ts
expandedDirectoryPaths resolves directory paths, keeps expanded ancestors consistent, and is used by expansion snapshots. FilesTab synchronizes the live expansion reference in an effect. Tests cover collapsed descendants.

Working-directory messages

Layer / File(s) Summary
Working-directory message wording
shell/ui/src/page/working-dir-scope.ts, shell/ui/src/page/__tests__/working-dir-scope.test.ts
The messages use sentence-separated wording and state that chat has no working directory yet.

Review message layout

Layer / File(s) Summary
Responsive review message layout
shell/ui/styles.css
Review messages with inline actions use a two-column layout on wide containers and a stacked layout below 720px.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 52ff9

The PR is mergeable with explicit follow-up: disabled inline review actions may still look interactive and show hover styling while saving, creating a bounded UI usability issue without affecting the underlying action safety.

Poem

A rabbit checks the folders in line
Collapsed paths now rest just fine
Messages speak with clearer cheer
Buttons fit when screens draw near
Fresh tests guard each change
Hop by hop, the tree stays in range

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Add a disabled state for .shui-review-inline-action.

ReviewPane.tsx renders this class with disabled={saving}. These rules keep cursor: pointer and apply the hover background to disabled buttons, so the inline action appears available while saving. Add a :disabled override after :hover with a non-interactive cursor and neutral background.

Proposed fix
 [data-iii-ui="shell"] .shui-review-inline-action:hover {
   background: var(--color-surface-hover);
 }
+[data-iii-ui="shell"] .shui-review-inline-action:disabled,
+[data-iii-ui="shell"] .shui-review-inline-action:disabled:hover {
+  cursor: default;
+  background: var(--color-bg);
