ยงConsensus

[NU6.3 onward] The enableCrossAddress flag of flagsOrchard MUST be 0.

An Orchard bundle can never carry this flag off the wire: bit 2 is rejected at deserialization for the Orchard pool in every tx version (only the Ironwood pool permits it). So this is a defense-in-depth check that also covers an in-memory-constructed bundle.
