In almost all instances the reasonable man theory usually prevailed. If you said you cleaned under your bunk during an inspection and they find that you did not, you are not going to get kicked out. If you say that you were studying when you were really making out on the town, you can get kicked out.
it may depend more on the school that has the honor code, rather then the honor code. except for the USNA, all these schools seem to have a similar code, like, "A cadet does not lie, cheat or steal, nor tolerate those who do." But for example, at VMI, I sort of get the sense there is zero tolerance for lies of any kind. for example, here is an article that mentions a cadet who got drummed out for not putting himself on report for being out of his room after lights-out, and having someone else rat him out first:

this is an old article, so maybe things have changed, but I'd be afraid to tell even the whitest lie and if I made a mistake under stress, for example, because the cadre was yelling in my face, I'd want to immediately correct anything I might have said that was wrong. I'd definitely want to tell whether or not I cleaned the floor. I don't know if that is the intent of the honor code, but I find it all pretty scary in how serious it all seems to be. At least I haven't read anything at all that seems to suggest that there is a reasonable man theory at VMI- nothing that says that some lies are punished less severely then others. I'm really under the impression that if the honor court finds you guilty of telling any lie at all, there is only one punishment - a drumming out.
