Signature

function isAbortCause(cause: unknown): boolean;

Returns true for an Error carrying the non-enumerable Symbol.for('defjs.cause.aborted') brand, including ERR_ABORTED from another Core copy, or a DOMException named AbortError. An ordinary unbranded Error with that name does not match. Other values return false.

Pass the underlying fault.cause; this function does not unwrap faults. createNetworkFault uses this check to select NET_ABORTED. OpenTelemetry uses it to suppress caller-cancellation logs while preserving timeout logs.
