## When to Apply

- Adding or modifying NgRx stores, reducers, or effects
- Writing selectors for state selection in components
- Managing collections with `@ngrx/entity`

## Rules

| Rule | Impact | Description |
|------|--------|-------------|
| Keep Reducers Pure | HIGH | No side effects in reducers; move HTTP calls to Effects |
| Use Feature Selectors | MEDIUM | Memoized selectors that recompute only when inputs change |
