Case contract

Given integer codes, an integer zero point, and a positive integer scale, return integer dequantized values as (code-zero_point)*scale. Scale is restricted to positive integers so results are exact integers.

Why this case matters

This deterministic model isolates one quantization arithmetic contract from tensor storage and runtime kernels.
