Over opener's raise, responder has two questions: does opener have a minimum or a maximum; and does opener have three card support or four card support.
1D 1H 2H 2N and 1D 1H 2H 3D are non-forcing game tries. Opener is allowed to pass with a minimum with three hearts.
Sorry for the confusion.
Yes, a lot of confusion, but not your fault - you explained things very clearly, more than once.

Auction (A) is not the same as Auction (B).
Auction (A), if we ignore for our purposes all slam tries, psyches, etc, and concentrate only on the case when Opener has an invitational hand, does not exist. If Opener A invites, and Responder A rejects the invitation, Opener A cannot logically do anything except Pass.
Auction (B) is quite different. It is possible for Responder B to have a hand that
- wants to be in 4H every time Opener has 4 hearts, but
- is happy to play 3D when Opener is minimum with 3 hearts.
So, when opener bids 3H, a 4H bid by responder is not the logical impossibility it was in auction A, but is the bid responder will make when he wants to be in game opposite all 4 card holdings.
Not sure why this is difficult. Perhaps some people misread the original post, concentrating on the (max, min) meaning of the 3D try, and overlooking the (3H, 4H) meaning.
OP was asking, it seems to me, whether the hand in question is suitable for bidding 4H whenever opener is known to have a 4 card suit.
That's impossible. No one can give more than one hundred percent. By definition that is the most anyone can give.
