Quantization: Output zero point is scaled with the accumulator · case 05

The output zero point changes with the requantization multiplier.

Case contract

Requantize centered input codes by multiplier/2**shift, then add output zero point in output-code units. Inputs follow this explicit integer toy contract; ties use Python round-to-even where rounding is required.

Why this case matters

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