## Key Design Decisions

### 1. Story Detail Page Layout

**Decision:** Two-column layout with main content + metadata sidebar

**Rationale:**
- Consistent with Epic detail page design
- Separates core content from metadata
- Optimizes for 80% use case (reading details)

**Layout:**
```
┌────────────────────────────────────────────────┐
│ [Breadcrumb] [←] Story Title    [Edit][Delete] │
├────────────────────────────────────────────────┤
│ ┌─────────────────────┐  ┌──────────────────┐ │
│ │ Story Details       │  │ Metadata Sidebar │ │
│ │ - Description       │  │ - Status         │ │
│ │ - Acceptance Criteria│  │ - Priority      │ │
│ │ - Tasks (8)         │  │ - Assignee       │ │
│ │ - Activity Timeline │  │ - Parent Epic    │ │
│ └─────────────────────┘  └──────────────────┘ │
└────────────────────────────────────────────────┘
```

### 2. Story Creation Flow

**Decision:** Hybrid approach (Quick Add + Full Form)

**Quick Add (Inline):**
- For rapid Story creation
- Title + Priority only
- Inline form at top of Stories section
- Keyboard shortcut: `Cmd/Ctrl + N`

**Full Form (Dialog):**
- For detailed Stories
- All fields available (description, assignee, acceptance criteria)
- Accessed via [+ New Story] button

**Rationale:**
- Supports both quick workflows and detailed planning
- Reduces clicks for common case (simple Story)
- Maintains consistency with Epic creation pattern

### 3. Kanban Board Enhancements

**Decision:** Add contextual Story creation from Epic cards

**New Interaction:**
```
Hover over Epic card → [+ Add Story] button appears
Click → Inline Story form opens below Epic card
Create → Story appears in correct Kanban column
```

**Rationale:**
- Reduces navigation (no need to open Epic detail)
- Maintains context (Epic visible while creating)
- Faster workflow for batch Story creation

### 4. Task Management in Story Detail

**Decision:** Expandable Task list with inline creation

**Features:**
- Checkbox for quick status toggle
- Filters: Status, Priority, Assignee
- Sort: Priority, Status, Date, Assignee
- Drag to reorder
- Inline Quick Add Task

**Rationale:**
- Tasks are critical to Story completion
- Users need quick Task updates without navigation
- Aligns with "Flow" principle (minimize steps)

### 5. Activity Timeline

**Decision:** Show full change history with filtering

**Display:**
- Icon-based event types (status, assignment, comment)
- Relative timestamps ("2h ago")
- Filters: All, Changes, Comments, Assignments
- Infinite scroll / Load More

**Rationale:**
- Transparency: Users see all changes
- Collaboration: Track team activity
- Audit trail: Compliance requirement

## Risk & Mitigation

### Risk 1: Complex Task Management
**Issue:** Task list with filters, sorting, drag-drop is complex

**Mitigation:**
- Start with basic Task list (Phase 1)
- Add features incrementally (Phase 3)
- Use proven library (@dnd-kit) for drag-drop
- Extensive testing with real users

### Risk 2: Real-time Update Conflicts
**Issue:** Multiple users editing same Story simultaneously

**Mitigation:**
- Optimistic UI updates with revert on conflict
- SignalR broadcasts changes to all users
- Show "Someone else is editing" indicator
- Auto-refresh on conflict detection

### Risk 3: Mobile UX Complexity
**Issue:** Story detail page has many sections for small screens

**Mitigation:**
- Use tabs on mobile (Details | Tasks | Activity)
- Bottom sheets for forms (not full dialogs)
- Progressive disclosure (collapse sections)
- Swipe gestures for common actions

### Risk 4: Performance with Large Task Lists
**Issue:** Stories with 50+ Tasks may be slow

**Mitigation:**
- Virtual scrolling for Task lists (react-window)
- Pagination or "Load More" for Activity Timeline
- Optimize SignalR payload size
- Backend pagination for Tasks API

## Questions for Product Team

1. **Acceptance Criteria:** Should this be a simple checkbox list or rich text?
2. **Story Status Transitions:** Are all transitions allowed (e.g., Done → Backlog)?
3. **Task Limits:** Is there a maximum number of Tasks per Story?
4. **Batch Operations:** Priority for bulk Story creation/update?
5. **Integrations:** Will Stories sync with external tools (GitHub, Jira)?
6. **AI Features:** Should AI suggest Story breakdown or acceptance criteria?

---

## Next Steps

1. **Design Review:** Schedule with Product, Engineering, QA teams
2. **Prototype:** Create Figma interactive prototype (optional)
3. **User Testing:** Test flows with Lisa (PM) and David (Dev) personas
4. **Implementation:** Start Phase 1 (Core Story Detail)
5. **Iteration:** Gather feedback after each phase, adjust design
