The Mining tab's earnings card walked all N wallet transactions on every frame to total Today / Yesterday / All time and pick the 4 most recent rows: four string compares per transaction plus a memo search on receives. It also ran localtime and mktime every frame to find local midnight. The pass is now a pure function behind a one-slot cache keyed on WalletState::tx_revision, the transaction count, the filter pill, the Solo/Pool mode, solo support and local midnight, with a 2 s maximum age as a safety net. It reruns only when one of those changes or the 2 s age runs out, instead of every frame. The totals are bit-identical (same loop, same summation order), and crossing local midnight still moves Today into Yesterday at once. Local midnight is recomputed only when the clock second changes, through the shared util::localTime; a failed localtime now yields a zeroed struct instead of an uninitialised one. The "x ago" labels and Est. Daily are still computed per frame. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
