# Type-Specific Detail Views - Quick Start

## 🚀 What Was Built

Phase 1 adds intelligent routing to type-specific detail views for Requirements, Tests, and Epics.

---

## 📁 Files Created

1. **EpicDetailView** → `/frontend/apps/web/src/views/details/EpicDetailView.tsx`
2. **ItemDetailRouter** → `/frontend/apps/web/src/views/details/ItemDetailRouter.tsx`
3. **Updated index** → `/frontend/apps/web/src/views/details/index.ts`
4. **Updated route** → `/frontend/apps/web/src/routes/projects.$projectId.views.$viewType.$itemId.tsx`
5. **Documentation** → `/frontend/apps/web/docs/TYPE_SPECIFIC_DETAIL_VIEWS.md`

---

## 🎯 How It Works

### Before
All items used the same generic `ItemDetailView`.

### After
Items route to specialized views based on type:

```typescript
ItemDetailRouter
├── requirement → RequirementDetailView (purple theme)
├── test → TestDetailView (green theme)
├── epic → EpicDetailView (deep purple theme)
└── others → ItemDetailView (fallback)
```

---

## 💡 Usage

### In Components
```tsx
import { ItemDetailRouter } from '@/views/details';

<ItemDetailRouter item={item} projectId={projectId} />
```

### In Routes
Already integrated! Just navigate to:
```
/projects/123/views/table/epic-456
```

The router automatically shows the correct view.

## 🎨 Views Summary

| Type | View | Theme | Key Features |
|------|------|-------|--------------|
| requirement | RequirementDetailView | Purple | EARS patterns, quality metrics, ISO 29148 |
| test | TestDetailView | Green | Execution, coverage, flakiness tracking |
| epic | EpicDetailView | Deep Purple | Business value, timeline, story breakdown |

---

## 🔧 Type Guards

The router uses these to determine the view:

```typescript
isRequirementItem(item) // → type === "requirement"
isTestItem(item)        // → type === "test" | "test_case" | "test_suite"
isEpicItem(item)        // → type === "epic"
```

From `@tracertm/types` package.

## 📊 Epic View Tabs

1. **Overview** - Business value, stories, completion %
2. **Epic Specification** - Objectives, scope, constraints
3. **Timeline** - Start/end dates, progress bar
4. **Stories** - User story links, themes
5. **Acceptance Criteria** - Success criteria, risks

---

## 🔗 Data Fetching

Each view uses specialized hooks:

```tsx
// Epic view
const { data: epicSpec } = useEpicSpecByItem(projectId, item.id);

// Test view
const { data: testSpec } = useTestSpecByItem(projectId, item.id);

// Requirement view
const { data: reqSpec } = useRequirementSpecByItem(projectId, item.id);
```
