From now on I beg acceptance of the following principle which is enforced rather strictly in Norway, and that further comments are made in recognition of this principle:
When a player has UI in the form of a missing alert (or other misinformation) from his partner he is required to continue his auction just as he would have done had the alert (or correct information) been given, i.e. he must assume that partner just forgot to alert and did not really misunderstand his call. He is specifically forbidden to base any of his further calls on the possibility, however high, that partner misunderstood his call except when the auction itself makes it clear that there are no other possibility.
If you are going to beg acceptance of a principle not written in the laws, then I suggest you need to cite an authority, such as WBF minutes or local regulation.
What exactly do you mean "is enforced rather strictly in Norway"?
First: We are very suspicious when somebody makes a call that apparently is artificial and then the partnership tries to convince opponents and/or directors that they have no agreement on this call.
If they can show convincing evidence of no partnership understanding, not even by partnership experience, fine. However, in that case they will need a convincing explanation on why they used the artificial call in the first place.
Otherwise we tend to rule that they indeed have the agreement (or understanding) that is consistent with their use of the artificial call and that they have provided opponents with misinformation.
Second: If there is an apparent misunderstanding within a partnership we do not allow a player to become aware of his mistake from anything other than the legal calls and plays. Alerts, missing alerts, questions, explanations whatever (you name it) are extraneous information, and once a player receives any such information and this information could be what helped him realize his mistake we do not allow him to act accordingly, but require him to continue his auction and play subject to his original mistake.
If subsequently we rule that he may have been awakened by such UI and consequently saved his side from a bad result we do adjust the result back to what should be expected had he not been awakened.
We consider being in full compliance with the laws on duplicate bridge.
In the case under discussion this means that North/South is considered to have the agreement that 2
♦ is a transfer bid, that North is mistaken and has given MI to opponents and UI to partner by not alerting and that South is not allowed to correct 2
♦X to 2
♥ unless he always would have done so if for instance North had alerted the 2
♦ transfer bid and then passed.
