I'm not sure that this CSP models effectively any used ocaps system. It
seems to me that most of them, if not all, are concurrent. That is,
while Alice waits for Carol's response, Bob can still send Carol a
request.

That seems the way authority is described here so far. It's pretty
conservative but you better be exagerating the authority of some
subjects than underestimating it.

Conservatively,
