Case contract

Given finite Python integer/float nonnegative RHS values and nonzero pivot coefficients, return basis index of the minimum exact represented rhs/coefficient over positive coefficients; tie by smallest basis index; None means unbounded.

Why this case matters

This deterministic solver-step model isolates an algorithmic invariant used by iterative optimization implementations.

One recorded failure
