Discover how material moves between tanks and plan two safe target arrangements.
Identify the hidden valves
There are four conserved material units. Two stages run in order. Each sends min(capacity, source quantity − threshold), never below zero. Material arriving in stage 1 is available in stage 2.
Your stage 1 model
Your stage 2 model
Plan two safe deliveries
A pump moves one unit before the stages run. Birch must finish every tick at 2 or less. Reach each exact target in at most four ticks.
Start 4 / 0 / 0 → Target 1 / 1 / 2

Experiment, make a prediction, and check your solution when ready.
Need a hint?
A pulse of one unit versus two reveals a threshold. After you identify the valves, waiting can be an effective control.
