There are some conflicts.

NetworkBehaviour.Prediction

//other similar
anyChanged |= (transform.position - _lastCheckedTransformProperties.Position).sqrMagnitude > v3Distance;

NetworkObject.Prediction

bool hasChanged = (transform.position - prtp.Properties.Position).sqrMagnitude >= v3Distance;

It's unsure if to compare float3 or Vector3. If you're using specific libraries (presumably Unity math) make sure these changes work with and without it please.

StripedRingQueue
Is missing #if THREADED_TICKSMOOTHERS wrap.
