Apply History listed only counts - '13 matches · 13 transactions' - which reads
identically whether the run renamed a merchant or split every transaction with
another participant. Revert is destructive, so that is not enough to decide on.
Two additions. Migration 0017 records rule_id, rule_name and source on each run:
rule_name is denormalised so history stays readable after a rule is edited or
deleted, and there is no FK so deleting a rule cannot cascade away the audit
trail. Both write paths now populate it - the condition-matched run and the
selection-based quick action.
And rows expand to show the run's snapshot set against current values: which
transactions were touched and what changed on each. Rows changed by something
else since the run are called out, because reverting restores the pre-run value
and would discard that later edit.
Runs recorded before this show 'Unknown rule' - the rule they came from is not
recoverable.
