Review
The few places where your input makes everything else more accurate: untagged spending, transfers the matcher couldn't place, items that never arrived, and the rules that automate it all.
0 ambiguous groups
Outflows where the automatic matcher couldn’t decide between multiple same-amount inflows. Pick the right inflow for each, dismiss if it isn’t a transfer at all, or skip and come back later. The matcher will leave dismissed rows alone on future runs.
