- `401`: Authentication required
- `403`: Insufficient permissions
- `404`: Resource not found
- `422`: The request has invalid field values, violates a business rule, or carries a query parameter the endpoint does not declare. Field validation errors use `type: validation_error` and include the affected fields in `details`. Business-rule errors identify the failed rule in `type`.
