The header tells clients where to poll after a 202 response from a long-running operation.

## Impact

- **Area:** API

A long-running operation without the standard Location header violates the RPC contract.

## LintDiff Equivalent

This rule corresponds to the LintDiff rule [LroLocationHeader](https://github.com/Azure/azure-openapi-validator/blob/main/docs/lro-location-header.md).

## ❌ Incorrect

```tsp
@armResourceOperations
interface Employees {
  delete is ArmResourceDeleteWithoutOkAsync<Employee, EmployeeProperties, LroHeaders = {}>;
}
```

## ✅ Correct

```tsp
@armResourceOperations
interface Employees {
  delete is ArmResourceDeleteWithoutOkAsync<Employee, EmployeeProperties>;
}
```

## Suppression

Suppress per the RPC guidelines; otherwise use the standard Async templates.
