# Polish: Error Handling

## Find
- Silent catches: `grep -rn "catch.*=>.*{}" --include="*.vue" --include="*.ts" src/`
- Empty try/catch: `grep -rn "catch.*{$" -A1` looking for immediate `}`
- Missing error states in views: check each view has `errorMessage` ref

## Fix Pattern
```typescript
.catch((err) => {
  console.error('[ComponentName] operation failed:', err)
  errorMessage.value = err instanceof Error ? err.message : 'Operation failed'
})
```

Template: `<p v-if="errorMessage" class="text-red-400 text-sm mt-2">{{ errorMessage }}</p>`

## Backend
- Replace `unwrap_or_default()` on serialization with proper error propagation
- Consistent RPC error structure: `{ error: { code: string, message: string } }`

## Verify
Both should return zero: silent catches and empty catch blocks.
