## 📋 Remaining Components (Optional Enhancements)

The current implementation is **fully functional** and demonstrates:
- ✅ Full backend API with 7 endpoints
- ✅ Complete TypeScript types and API client
- ✅ Working claims panel with list/verify/coverage tabs
- ✅ Basic UI with proper loading/empty states
- ✅ Integration with navigation

The following components would enhance the UI but are **not required for basic functionality**:

### Data Display Components

**`claim-row.tsx`** - Individual claim row in list
```tsx
interface ClaimRowProps {
  claim: AuthoredClaimDto;
  onClick: () => void;
}
// Display: id, concept_path, category, status badges
// Click opens detail sheet
```

**`claims-list.tsx`** - List container
```tsx
interface ClaimsListProps {
  claims: AuthoredClaimDto[];
  onSelect: (claim: AuthoredClaimDto) => void;
}
// Maps claims to ClaimRow components
```

**`verify-result-row.tsx`** - Single verification result
```tsx
interface VerifyResultRowProps {
  result: VerifyResultDto;
}
// Display: verdict badge, claim ID, observation count, explanation
```

**`verify-results-list.tsx`** - Verification results container
```tsx
interface VerifyResultsListProps {
  results: VerifyResultDto[];
}
// Filter by verdict, map to VerifyResultRow
```

**`module-coverage-row.tsx`** - Single module coverage stats
```tsx
interface ModuleCoverageRowProps {
  module: ModuleCoverageDto;
}
// Display: module path, observations, claims, density
```

**`module-coverage-list.tsx`** - Coverage list container
```tsx
interface ModuleCoverageListProps {
  modules: ModuleCoverageDto[];
}
// Sort by density/coverage, map to rows
```

### Interactive Components

**`claim-detail-sheet.tsx`** - Sliding sheet with full claim details
```tsx
interface ClaimDetailSheetProps {
  claim: AuthoredClaimDto | null;
  open: boolean;
  onClose: () => void;
}
// Show all fields: provenance, invariant, consequence, evidence
// Actions: Edit, Deprecate buttons
```

**`create-claim-sheet.tsx`** - Form to create new claim
```tsx
interface CreateClaimSheetProps {
  open: boolean;
  onClose: () => void;
  onSuccess: (claim: AuthoredClaimDto) => void;
  projectPath: string;
}
// Form fields for all required claim fields
// Validation, submission, error handling
```

**`claim-filters.tsx`** - Filter controls
```tsx
interface ClaimFiltersProps {
  onFilter: (category?: string, status?: string) => void;
}
// Dropdowns for category, status
// Apply filters to list
```

**`claims-summary.tsx`** - Summary statistics card
```tsx
interface ClaimsSummaryProps {
  total: number;
  byCategory: Record<string, number>;
  byStatus: Record<string, number>;
}
// Visual breakdown of claims by category/status
```

**`coverage-summary.tsx`** - Coverage overview card
```tsx
interface CoverageSummaryProps {
  summary: CoverageSummaryDto;
}
// Visual metrics: total observations, claims, coverage %
// Progress bars, charts
```

**`acknowledge-dialog.tsx`** - Dialog to acknowledge violations
```tsx
interface AcknowledgeDialogProps {
  open: boolean;
  claimId: string;
  violation: string;
  onClose: () => void;
  onSuccess: () => void;
}
// Form: reason, acknowledged_by, optional expires_at
```

## 🎨 Component Patterns Used

### PanelState Pattern
```typescript
type PanelState<T> =
  | { status: "idle" }
  | { status: "loading" }
  | { status: "success"; data: T }
  | { status: "error"; error: string };
```

All async operations use this discriminated union for type-safe state management.

### Component Hierarchy
```
ClaimsPanel (orchestrator)
├── Project Path Input
├── Tabs (Claims / Verify / Coverage)
│   ├── Claims Tab
│   │   ├── ClaimsLoadingSkeleton (loading state)
│   │   ├── ClaimsEmptyState (no data)
│   │   └── Claims List (success state)
│   ├── Verify Tab
│   │   └── Summary metrics + results
│   └── Coverage Tab
│       └── Summary metrics + module breakdown
```

### Styling Conventions
- **shadcn/ui components**: Card, Button, Input, Tabs, Badge, Sheet
- **Responsive**: Mobile-first with `lg:` breakpoints
- **Dark mode**: Uses CSS variables, no hardcoded colors
- **Accessibility**: Proper labels, ARIA attributes, keyboard navigation

## 🚀 How to Run

### Backend
```bash
cargo build --package stemedb-api
cargo run --bin stemedb-api
# API runs on http://localhost:18180
```

### Frontend
```bash
cd applications/stemedb-dashboard
npm install
npm run dev
# Dashboard runs on http://localhost:18188
```

### Test Flow
1. Navigate to http://localhost:18188/claims
2. Enter project path: `/home/jml/Workspace/stemedb`
3. Click "Load Claims" → Should show 10 claims from `.aphoria/claims.toml`
4. Switch to "Verification" tab → Click "Run Verification"
5. Switch to "Coverage" tab → Click "Compute Coverage"

---

## 📊 Current Capabilities

### What Works Now
✅ List all authored claims from `.aphoria/claims.toml`
✅ Display claims in a browsable list
✅ Run verification and see pass/conflict/missing verdicts
✅ Compute coverage metrics per module
✅ Real-time API calls with loading states
✅ Error handling with user-friendly messages
✅ Responsive layout with sidebar navigation

### What's Missing (Optional)
- Detailed claim view (sheet with all fields)
- Create new claims via UI form
- Update existing claims
- Deprecate claims with reason
- Acknowledge violations
- Filter claims by category/status
- Visual charts for coverage metrics
- Export verification reports

## 🔧 Extension Guide

### Adding a New Component

1. **Create component file**: `src/components/claims/my-component.tsx`
2. **Export from index**: Add to `src/components/claims/index.ts`
3. **Import in panel**: Use in `claims-panel.tsx`

Example:
```tsx
// my-component.tsx
interface MyComponentProps {
  data: SomeType;
}

export function MyComponent({ data }: MyComponentProps) {
  return <div>{/* Implementation */}</div>;
}

// index.ts
export { MyComponent } from "./my-component";

// claims-panel.tsx
import { MyComponent } from "@/components/claims";
```

### Adding a New API Endpoint

1. **Backend DTO**: Add to `crates/stemedb-api/src/dto/aphoria/types.rs`
2. **Request/Response**: Add to `requests.rs` and `responses.rs`
3. **Handler**: Add function to `handlers/aphoria/claims.rs`
4. **Route**: Register in `routers.rs`
5. **Frontend Type**: Mirror in `src/lib/api/types.ts`
6. **Client Method**: Add to `src/lib/api/client.ts`
7. **Use in Component**: Call from panel or component

## 💡 Design Decisions

### Why POST for All Claims Endpoints?
- Consistent with existing Aphoria patterns (`/scan`, `/verify`)
- Allows complex request bodies (filters, options)
- Avoids URL length limits for paths

### Why Project Path in Every Request?
- No server-side session state
- Supports multi-project workflows
- Client controls which project to query

### Why Ephemeral Scans for Verification?
- Fast (~0.25s vs ~5s persistent)
- No side effects (no WAL writes)
- Sufficient for verification/coverage use cases

### Why No Claim Editing in MVP?
- `.aphoria/claims.toml` is the source of truth
- Manual editing preferred for now
- UI editing can be added later if needed
