Opener starts with 1♦ and then rebids 1♠ after a 1♥ response, and this is defined as showing an unbalanced hand, a good agreement IMO.
Responder then bids 2♣, GF and artificial.
Opener has already stated that he is unbalanced. If he had 4351 or 4360, I assume that he is not an idiot and would next bid 2♥. Failing to do that, we can eliminate that option.
If Opener rebids 2♠ at this point, he presumably has 5♠/6♦.
If Opener started with 4054, he would surely bid 3♣ at this point.
The only hand patterns left seem to be 4252 (if that is possible), 4153, or hands with six diamonds. However, the 2NT rebid has not been used, which seems to also cover some of this territory.
It seems to me, therefore, that Opener only have five diamonds when his clubs suck.
Assuming this, then I agree with Zelandakh that 3♣ really should be used (in theory) as a continuing notrump probe but 2NT as assured club values but extras and interest. Opener could then repeat his diamonds, and then a serries of nice calls should get this to the ideal contract, assuming an intelligent approach.

And we ask police officers, prosecutors, defense lawyers, and citizens to enforce or abide by it? The legislature continues to write unreadable statutes. Gibberish should not be enforced as law."
