+-- Table with historic business ledger; basically, when the exchange
+-- operator decides to use operating costs for anything but wire
+-- transfers to merchants, it goes in here.  This happens when the
+-- operator users transaction fees for business expenses. purpose
+-- is free-form but should be a human-readable wire transfer
+-- identifier.   This is NOT yet used and outside of the scope of
+-- the core auditing logic. However, once we do take fees to use
+-- operating costs, and if we still want auditor_predicted_result to match
+-- the tables overall, we'll need a command-line tool to insert rows
+-- into this table and update auditor_predicted_result accordingly.
+-- (So this table for now just exists as a reminder of what we'll
+-- need in the long term.)
