## Implementation Strategy

### Reuse Epic Pattern Strategy

**Key Insight**: Story detail page is 85% similar to Epic detail page

Reuse Plan:
1. Copy Epic detail page structure → Story detail page
2. Adapt Epic form enhancements → Story form
3. Reuse Epic card patterns → Story card component
4. Copy Epic status/priority logic → Story metadata

**Benefits**:
- **Consistency**: Visual and interaction consistency across the app
- **Speed**: 50-60% faster development through code reuse
- **Quality**: Proven patterns, fewer bugs
- **Maintenance**: Shared components easier to maintain

### Story vs Epic Differences

**Key Distinctions**:
1. **Stories have Tasks**, Epics have Stories
2. **Stories are smaller**, typically 1-2 week effort
3. **Stories have acceptance criteria**, Epics have high-level goals
4. **Stories assignable to individuals**, Epics to teams
5. **Stories more granular tracking**, Epics high-level progress

**Implementation Impact**:
- Story detail shows **Task list** (not Story list)
- Story form includes **acceptance criteria** field
- Story cards show **Task count** (not Story count)
- Story hierarchy: Epic → **Story** → Task

## Backend API Verification Checklist

Frontend team should verify these before Day 1:
- [ ] GET /api/v1/stories/{id} returns Story with all fields
- [ ] GET /api/v1/stories/{id}/tasks returns Task list
- [ ] POST /api/v1/tasks with storyId creates Task correctly
- [ ] PUT /api/v1/stories/{id} accepts all fields
- [ ] DELETE /api/v1/stories/{id} cascades to Tasks
- [ ] Multi-tenant isolation works (cannot access other tenant Stories)
