Combine weights are normalized across unrelated tokens · case 02

Combine weights are normalized across unrelated tokens.

Member previewVariant 2 · 3 implementations · 6 checks per implementation

Case contract

Rows [token,expert,weight]; return rows in order with each weight divided by its token total.

Why this case matters

A deterministic toy router makes this dispatch decision independently inspectable.
