To my mind we should follow the claim statement as far as possible. Declarer has made a pretty unequivocal statement about the next 4 cards she intends to play. Of course she can't discard two diamonds from dummy but this doesn't prevent or preclude the play of the next 4 cards as in the claim statement.
Is there guidance on how far we should follow claim statements in cases like this?
Yes, there is, you're looking for:

Suppose a player claims, and part of his claim is to discard a club on dummy’s diamond. Unfortunately he will have to follow suit at that time: how does the Director rule?
The revoke is not accepted by the Director, so he follows the claim statement up to the revoke, and then treats it as though there was no further statement. However, if a later part of the claim appears to be valid he should take account of that in his considerations. The same applies for any other irregularity embodied in a claim

Sometimes the deal would become clear if it were played out. At such times the Director does not assume a player would have taken a line that has become irrational by seeing the cards played.
In this case, it seems to me that declarer would immediately notice the problem when the first club in played and defence reject the revoke and will then take careless but not irrational lines which involve a cross-ruff, since that is a later parrt of the claim which appears valid. Given it's clearly at most careless (and possibly the percentage line) to play for split honours, I'd rule a diamond trick to defence.
