+ * @title SelfRegisterSqrtTaskMiddleware
+ * @notice Middleware for managing sqrt computation tasks with self-registering operators
+ * @dev Uses SelfRegisterOperators for operator management because it allows permissionless registration.
+ * Task validation is done by a single validator chosen at task creation time because this avoids
+ * having to iterate over all operators, making it more gas efficient and avoiding potential DOS attacks.
