+- [x] TaskApiClient with CRUD methods
+- [x] Axios interceptors for authentication
+- [x] Error handling and validation
+
+### AC2: React Query Hooks ✅
+- [x] useEpics, useCreateEpic, useUpdateEpic, useDeleteEpic
+- [x] useStories, useCreateStory, useUpdateStory, useDeleteStory

+
+## Implementation Summary
+
+### Files Created
+1. **API Client Services** (lib/api/pm.ts) - Already existed
+   - epicsApi with full CRUD operations
+   - storiesApi with full CRUD operations
+   - tasksApi with full CRUD operations
+
+2. **React Query Hooks** (lib/hooks/)
+   - use-epics.ts - Epic query and mutation hooks with optimistic updates
+   - use-stories.ts - Story query and mutation hooks with optimistic updates
+   - use-tasks.ts - Task query and mutation hooks with optimistic updates
+
+3. **Form Components** (components/projects/)
+   - epic-form.tsx - Epic creation/editing form with Zod validation
+   - story-form.tsx - Story creation/editing form with parent epic selection
+   - task-form.tsx - Task creation/editing form with parent story selection
+
+4. **Hierarchy Visualization** (components/projects/)
+   - hierarchy-tree.tsx - Tree view with expand/collapse functionality
+   - work-item-breadcrumb.tsx - Breadcrumb navigation for Epic → Story → Task
+
+5. **Export Index** (components/projects/index.ts)
+   - Centralized exports for all project components
+
+### Technical Highlights
+- TypeScript type safety throughout
+- Zod schema validation for all forms
+- React Query optimistic updates
+- Hierarchical data loading (lazy loading stories/tasks on expand)
+- Responsive UI with Tailwind CSS
+- Loading states and error handling
+- JWT authentication integration
