On the other hand though, there's no rule which prohibits writing:

nuHIvbe' rIntaH

nuHIvlaw' rIntaH

For reasons I can't understand, there's something weird in "they've not attacked us and it cannot be undone".

They had just one chance to attack us, but they let it slip by, and now they won't get another chance.

And it's even weirder to hear "seemingly/apparently they attacked us and it cannot be undone".

The evidence suggests that the enemy launched a full-scale assault on the home world while were were out here on the frontier. That means we're at war now.

I mean, how can you say that the attack cannot be undone, if you can't be sure it happened in the first place ?

But if it DID happen, you know it happened with finality.

Let alone the fact that we *can* write:

nuQaHneS rIntaH

Where we have the type-7 {-taH} being preceded by the type-8 {-neS}. Of course, they're on different words, but neverthless the "feel" I always got from the {rIntaH} was that it is a member of the type-7 verb suffix family.

To use rIntaH is to use a variant of the sentence-as-object construction. Suffix order is arbitrary and irrelevant when suffixes are on different words. rIntaH is not a suffix and should not be thought of as a suffix.
