Dropped routes make surviving token weights sum to less than one · case 04

Dropped routes make surviving token weights sum to less than one.

Member previewVariant 4 · 3 implementations · 6 checks per implementation

Case contract

Routes [token,expert,weight] arrive in order; accept up to capacity per expert, then normalize each token’s accepted weights.

Why this case matters

A deterministic toy router makes this dispatch decision independently inspectable.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
