I just spent an hour reading about sentences like this:
I am sat here.
She was stood there.
In this question people tackle whether it's correct usage or not, which is not the point of my question.
Few people would argue that "I am done here" is non-standard English. 'Done', the past participle of 'do', is listed in the Oxford Dictionary of English as an adjective, so it's easy to see why "I am done here" is standard.
The verbs "sat" and "stood" are both past participles, but they are not listed as adjectives in the same dictionary. Are they acting as adjectives in the two example sentences?

An intransitive verb is one that cannot take a direct object. Normally, intransitive verbs cannot be made passive.
The past participle is normally passive (except with have).
From this it follows that intransitive verbs, like sit and stand in the senses intended, normally cannot have past participles without have.
However, there are some intransitive verbs that are best considered idiomatic exceptions: they can still have past participles. You could say those exceptional past participles don't have the normal passive sense. You might call them adjectivised, but I'm not sure I'd pick that term, considering that sat and stood cannot be used attributively (before the noun).
