**Lines**: 62, 66  
**Error**: `Type 'T' does not satisfy the constraint 'QueryResultRow'`  
**Fix**:
```typescript
// Change from:
export async function query<T = unknown>

// To:
export async function query<T extends QueryResultRow = QueryResultRow>
```

#### 2. Database Package - Unknown Type in Union
**File**: `packages/database/src/client.ts`
