Use current codes once, then measure five comparable Cash runs.
Use the ordered Cash methods: current one-time codes first, then five comparable runs with confidence labels, stuck-state fixes, and the player-input calculator link. Keep uncertainty notes for multipliers and quests, and leave unknown payouts unclaimed. Plan from the conservative result, not the best run, because the game does not publish a permanent Cash-per-minute table.
For ghost driver money fast, use current in-game Cash results, test repeatable runs, and reject unverified multiplier promises.
