Questions about envelope validator
What does the validator check in X12?
It checks ISA13/IEA02, GS06/GE02, ST02/SE02, declared group and transaction counts, and each ST-through-SE segment count.
Does a green result certify compliance?
No. It only reports the specific structural relationships shown in the evidence list.
