🧠 How CrossFire works
CrossFire is a structured playset generator — structure, reduction and exact cost.
A < B < C < D
Every four-distinct-digit Pick 4 box can be sorted this way. CrossFire divides it into:
A | BC | D
A
Low
The smallest digit in the sorted box.
BC
Middle pair
The two inside digits, in ascending order.
D
High
The largest digit in the sorted box.

What CrossFire is — and isn't
Selecting LOW + MIDDLE + HIGH is not three independent confirmations. Those three choices together define complete Pick 4 boxes. CrossFire exists for structure, number reduction, playset generation, exact cost, coverage visualization, historical organization and budget control — never for prediction.
