Assert the deadline-triggered workflow requeue.

This test calls operate directly and checks only node phases. Removing AddRateLimited would leave these assertions passing. No other inspected test covers this retry swap-back requeue path.

Suggested fix

 	newWorkflowOperationCtx(ctx, woc.wf.DeepCopy(), controller).operate(ctx)
 	total := time.Since(start)
+	key, err := cache.MetaNamespaceKeyFunc(wf)
+	require.NoError(t, err)
+	requeuesBefore := controller.wfQueue.NumRequeues(key)

 	for offset := time.Duration(0); offset < total; offset += total / 2000 {
 		sweepWoc := newWorkflowOperationCtx(ctx, woc.wf.DeepCopy(), controller)
 		sweepWoc.deadline = time.Now().UTC().Add(offset)

Update the deadline sweep test around
`newWorkflowOperationCtx(...).operate(ctx)` to assert that deadline handling
schedules a workflow requeue. Capture the workflow queue’s requeue count for the
workflow key before the sweep and verify it increases afterward, while
preserving the existing node-phase assertions.

Make deadline expiration deterministic in this test.

The completed-DAG fixture and NodeError assertion can detect the regression only if the retry swap-back path runs. The wall-clock sweep does not guarantee that. It can miss the narrow deadline window, and the test has no assertion or instrumentation for ErrDeadlineExceeded or branch entry. Use a test clock or expire the deadline after a fixed number of checkDeadline calls.

Update the deadline sweep in the completed-DAG test to deterministically reach
the retry swap-back path instead of relying on wall-clock timing. Use a test
clock or control the deadline after a fixed number of `checkDeadline` calls, and
assert that the deadline-expiration path is reached before checking that no node
enters `NodeError`.

Make the deadline trigger deterministic.

handleRetries checks the deadline only after next makes the retry child fulfilled. The test samples deadlines from a different reconcile duration, so no sample is guaranteed to fall between child fulfillment and retry re-entry. The old error-marking path can therefore remain untested while the sweep passes.

Use a deterministic callback or focused handleRetries test that expires the deadline after the child becomes Succeeded, then assert ErrDeadlineExceeded, a non-Error retry parent, and the child’s Succeeded phase. The zero-step guard prevents an infinite loop, but it does not guarantee coverage of the affected interval.

Replace the timing-based sweep in
TestRetryNodeDeadlineExceededKeepsSucceededChild with a deterministic deadline
trigger that expires after the retry child becomes Succeeded and before the
retry parent is re-entered. Assert ErrDeadlineExceeded, that the retry parent is
not Error, and that the child remains Succeeded.
