### Issues Found

#### 🟡 Minor Issues

1. **Assignee Selector Limited** (Medium Priority)
   - Only shows current user
   - No team member list
   - **Fix**: Fetch team members from API (e.g., /api/projects/{id}/members)
   - **File**: `story-form.tsx:332-336`

2. **No Assignee Name Display** (Low Priority)
   - Form only stores assigneeId

   - **Fix**: Add assigneeName field to Story type, populate on backend

3. **Tags Not Pre-populated for Project** (Low Priority)
   - User must type all tags manually
   - No suggestion based on existing project tags
   - **Fix**: Add tag autocomplete with existing tags

### Recommendations

1. **Enhance Assignee Selector**
   ```tsx
   // Fetch team members
   const { data: teamMembers } = useQuery({
     queryKey: ['team-members', projectId],
     queryFn: () => projectsApi.getMembers(projectId),
     enabled: !!projectId,
   });

   // Display in dropdown
   <SelectContent>
     <SelectItem value="">Unassigned</SelectItem>
     {teamMembers?.map((member) => (
       <SelectItem key={member.id} value={member.id}>
         <div className="flex items-center gap-2">
           <Avatar size="sm">
             <AvatarFallback>{member.initials}</AvatarFallback>
           </Avatar>
           <span>{member.fullName}</span>
         </div>
       </SelectItem>
     ))}
   </SelectContent>
   ```

2. **Add Tag Autocomplete**
   ```tsx
   // Fetch existing tags
   const { data: existingTags } = useQuery({
     queryKey: ['project-tags', projectId],
     queryFn: () => projectsApi.getTags(projectId),
   });

   // Use Combobox component for autocomplete
   <Combobox
     options={existingTags}
     value={field.value}
     onChange={field.onChange}
     placeholder="Add tags..."
   />
   ```

3. **Validation Improvements**

   - Add max number of acceptance criteria (e.g., 20 items)
   - Add max number of tags (e.g., 10 tags)
   - Add tag length validation (e.g., 2-50 chars)

**Test Cases**:
1. **Task List in Story Detail** ✅
   - TaskList component renders in Story Detail page
   - Receives correct storyId prop
   - Tasks are scoped to current story
   - Loading/error states propagate correctly

2. **Task Updates Reflect in Story** ✅
   - Creating task refreshes story details
   - Deleting task refreshes story details
   - Task status changes visible immediately (optimistic updates)

### ✅ Story 1 ↔ Story 3 Integration (PASS)

**Test Cases**:
1. **Edit Story Opens Enhanced Form** ✅
   - Edit button opens StoryForm with story data
   - All new fields (acceptance criteria, tags, story points) are editable
   - Form prefills with existing data
   - Updates are saved correctly

2. **New Fields Display (Needs Implementation)** 🟡
   - Acceptance criteria NOT displayed in Story Detail

---

## Performance Analysis

### React Query Optimization

**Caching Strategy**:
- Stories: staleTime 5 minutes
- Tasks: staleTime 5 minutes
- Automatic cache invalidation on mutations
- Optimistic updates for better UX

**Optimization Opportunities**:
1. Add prefetching for story navigation
2. Consider longer stale time for stable data
3. Add infinite scroll for large task lists

### Component Rendering

**Optimizations**:
1. TaskCard uses useState for expand/collapse (no re-render parent)
2. TaskList filters/sorts in component (no API calls)
3. Proper use of React.memo candidates:
   - TaskCard (re-renders on every task update)
   - AcceptanceCriteriaEditor (re-renders on form changes)
   - TagsInput (re-renders on form changes)

**Recommendations**:
```tsx
export const TaskCard = React.memo(TaskCardComponent, (prev, next) => {
  return prev.task.id === next.task.id &&
         prev.task.status === next.task.status &&
         prev.task.title === next.task.title;
});
```

   - Tab moves between inputs
   - Focus management on add/remove

4. **Tags Input** ✅
   - Enter adds tag
   - Backspace removes last tag
   - Proper focus management

### ✅ Screen Reader Support (PASS)

**Test Cases**:
1. **Semantic HTML** ✅
   - Proper heading hierarchy (h1, h3)
   - Landmark elements (nav, main, aside implied by layout)
   - Buttons have accessible labels
   - Links have descriptive text

2. **ARIA Attributes** ✅

   - Loading states have aria-busy (implicit in skeletons)

3. **Form Labels** ✅
   - All form fields have FormLabel components
   - FormDescription for additional context
   - FormMessage for error feedback

### 🟡 Areas for Improvement

1. **Task Card Expand/Collapse**
   - Add aria-expanded attribute
   - Add aria-label for expand button

2. **Task Checkbox**
   - Add aria-label describing the task
   - Current: relies on visual context

3. **Filter/Sort Dropdowns**

### Medium Priority Issues: 2

1. **Story Detail Missing New Fields Display** (Story 1 + Story 3)
   - Location: `app/(dashboard)/stories/[id]/page.tsx`
   - Impact: Acceptance criteria, tags, and story points not visible in detail view
   - Workaround: Edit story to view these fields
   - Estimated Fix Time: 1-2 hours

2. **Assignee Selector Limited to Current User** (Story 3)
   - Location: `story-form.tsx:332-336`
   - Impact: Cannot assign stories to team members
   - Workaround: Manually set assigneeId in database
   - Estimated Fix Time: 3-4 hours (requires API endpoint)

### Low Priority Issues: 4

1. **Assignee Name Display**
   - Shows assigneeId instead of user name
   - Estimated Fix Time: 1 hour (backend + frontend)

2. **Task Description Missing in Quick Add**
   - Quick add only has title, priority, hours
   - Estimated Fix Time: 30 minutes

3. **No Task Status Filter**
   - Filter only has All/Active/Completed
   - Estimated Fix Time: 1 hour

4. **Tags Not Pre-populated**
   - No autocomplete for project tags
   - Estimated Fix Time: 2 hours
