Two aspects you missed...
Recognizing a disproportion is also a fundamental cue for laughter -- and while that's an element in several forms of humor, it can operate outside a social context entirely. A related form is the "mock threat", as exemplified by tickling. (That is, someone is forcibly touching you, but you know it's not really an attack.) One psychologist I know commented that "laughter is a gasp followed by a sigh of relief".
Also, in transactional psychology, laughter can be merely a "stroke" in various games or scripts.
