+
+## Story: Frontend: DiffControlBar comprehensive interaction tests
+
+### Pass Criteria
+
+- [x] At least 28 total tests (including existing 23) covering additional interaction edge cases
+  - Result: 32 total tests (19 existing + 13 new)
+- [x] WORKDIR display text verified
+  - Test: `__WORKDIR__ displays as My Working Directory in base branch selector`
+  - Test: `displays "My Working Directory" for __WORKDIR__ branch` (existing)
+- [x] Disabled state comprehensively tested
+  - Test: `disables all controls when disabled prop is true` (existing)
+  - Test: `all controls are enabled when disabled prop is false`
+  - Test: `disabled prop overrides individual button enable conditions`
+  - Test: `delete button is disabled when no workspace is selected`
+  - Test: `save button is disabled when currentWorkspacePath is empty`
+- [x] All tests pass with `npm --workspace apps/desktop run test`
+  - Result: 307 tests pass across 21 test files (0 failures)
+
+### New Tests Added (13)
+
+1. `delete button is disabled when no workspace is selected`
+2. `delete button is enabled when a workspace is selected`
+3. `save button is disabled when currentWorkspacePath is empty`
+4. `workspace selector shows unsaved label with folder name when no workspace selected`
+5. `workspace selector shows "Unsaved Workspace" when no path provided and no workspace selected`
+6. `workspace options display name and folder name`
+7. `selecting empty workspace ID calls onWorkspaceSelect with empty string`
+8. `workspace selector shows fallback text for unknown workspace ID`
+9. `workspace selector has title attribute showing workspace path`
+10. `workspace selector title shows selected workspace path when workspace is selected`
+11. `__WORKDIR__ displays as My Working Directory in base branch selector`
+12. `all controls are enabled when disabled prop is false`
+13. `disabled prop overrides individual button enable conditions`
+

+- Guardrails reviewed: yes
+- No-commit run: false
+- Commit: 7789299 test(desktop): add DiffControlBar comprehensive interaction tests
+- Post-commit status: clean
+- Verification:
+  - Command: npm --workspace apps/desktop run test -> PASS (307 tests, 21 files)
+  - Command: cargo test --manifest-path apps/desktop/src-tauri/Cargo.toml -> PASS (44 tests)
+  - Command: cargo clippy --manifest-path apps/desktop/src-tauri/Cargo.toml -- -D warnings -> PASS
+  - Command: npm run web:build -> PASS
+- Files changed:
+  - apps/desktop/src/components/DiffControlBar.test.tsx (expanded from 19 to 32 tests)
+- What was implemented:
+  - Added 13 new interaction tests to DiffControlBar.test.tsx for a total of 32 tests
+  - New tests cover: delete button enable/disable based on workspace selection, save button disabled without path, unsaved workspace label variants, workspace option display format, fallback for unknown workspace IDs, workspace selector title attribute, WORKDIR in base selector, comprehensive enabled/disabled states, disabled prop overriding individual conditions
+- **Learnings for future iterations:**
+  - The existing test file had 19 tests (not 23 as stated in story). The 28 target was still met and exceeded.
+  - DiffControlBar uses conditional rendering for unsaved/fallback options in the workspace selector
+  - The workspace title attribute uses selectedWorkspace.path falling back to currentWorkspacePath
