The clearest case in the domain where the bottleneck is coordination rather than computation. Detection takes minutes; resolution takes three days of email between teams in different time zones. Drafting the query with both sides' positions and the supporting document attached first time removes most of the round trips.
The query before sending, and the agreed resolution before either side posts a correction.
Post a correcting entry in either entity, or agree a resolution on behalf of a team. Both sides must own the agreement.
Both entities' ledger positions; applicable FX rate and convention; transaction documents; prior resolutions for the pair
Break analysis with the FX component separated from the residual, likely cause identified, and a drafted query with documents attached
The domain supports the pattern and no vendor in this model sells it. That is a statement about the market rather than about the pattern; v_agent_gaps lists them.
