<objective>
Add tests for utility components: GlobalImageHistory, GroupsOverlay, and ModelParameters.

Purpose: Test supporting UI components for history browsing, group visualization, and parameter editing.
Output: Test files covering component rendering, data display, and interactions.

<tasks>

<task type="auto">
  <name>Task 1: Add GlobalImageHistory component tests</name>
  <files>src/components/__tests__/GlobalImageHistory.test.tsx</files>
  <action>
Create comprehensive tests for GlobalImageHistory:
- Not rendered when closed/hidden
- Rendered when opened (panel visible)
- Toggle button to open/close
- Image grid rendering with thumbnails
- Empty state when no history
- Image click selecting/previewing image
- Delete image from history
- Pagination or infinite scroll (if applicable)
- Filter by type (image vs video) if applicable
- Date grouping or sorting

Mock useWorkflowStore for: imageHistory, loadImageHistory, deleteFromHistory.
Mock fetch for /api/load-generation endpoint.
  </action>
  <verify>npm test -- --run src/components/__tests__/GlobalImageHistory.test.tsx passes</verify>
  <done>GlobalImageHistory tests cover rendering, navigation, and deletion</done>
</task>

<task type="auto">
  <name>Task 2: Add GroupsOverlay and ModelParameters tests</name>
  <files>src/components/__tests__/GroupsOverlay.test.tsx, src/components/__tests__/ModelParameters.test.tsx</files>
  <action>
**Create GroupsOverlay.test.tsx:**
- Renders group backgrounds for each group in groups object
- Group color applied to background
- Group position and size from group data
- No rendering when no groups exist
- Group selection highlighting
- Z-index layering correct (below nodes)

**Create ModelParameters.test.tsx:**
- Basic rendering with parameter list
- Different input types based on parameter schema:
  - Number input for numeric params
  - Text input for string params
  - Select for enum params
  - Checkbox for boolean params
  - Slider for range params (min/max)
- Collapsed state (parameters hidden)
- Expanded state (parameters visible)
- Toggle collapse/expand
- Parameter value change calls onParameterChange
- Default values displayed
- Parameter descriptions/tooltips

Mock useWorkflowStore if needed.
Pass props: parameters (schema), values, onChange, collapsed, onToggleCollapse.
  </action>
  <verify>npm test -- --run src/components/__tests__/ passes utility component tests</verify>
  <done>GroupsOverlay and ModelParameters have comprehensive test coverage</done>
</task>

Before declaring plan complete:
- [ ] `npm test -- --run` passes all tests
- [ ] `npm run build` succeeds without errors
- [ ] Image history navigation tested
- [ ] ModelParameters input types tested
</verification>

<success_criteria>

- All tasks completed
- All verification checks pass
- No TypeScript errors
- ~15-20 new tests for utility components
- Phase 17 complete: all 34 components have test coverage
</success_criteria>

<output>
After completion, create `.planning/phases/17-component-tests/17-11-SUMMARY.md` with:
- Total test count increase
- Component coverage summary
- Any patterns established
- Ready for Phase 18 (API Route Tests)
</output>
