Misha can still reproduce. With limit=10000, server returns ~3000 items but claims ~4000 items_available.

2209-correct-items-available looks like a nice clean branch to me. Just one thing: in the test, the assignment for unique_uuids doesn't seem to actually ensure uniqueness, as far as I can tell. Should it? That'd be easy to do with a set operator, like unique_uuids = [] | resp['items'].collect { |i| i['uuid'] }.compact.

Either way, I think this is good to merge.
