Whether anything was recorded about a Client since you last looked, from one statement, with nothing derived.
GET
How far a Client’s recorded facts reach: the latest moment anything was recorded about the Client — its Loans, every act and retraction on them, its Receipts and their reversals — and how many such facts there are. Nothing is derived to answer it; it is one statement.
