Case contract

For unique candidate names and a unique partial ranking, return scores in candidate order; ranked position i earns m-1-i and omitted candidates earn zero.

Why this case matters

A deterministic toy ballot model makes the stated counting convention executable.

One recorded failure

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
single ranked candidate	`[0, 0, 0, 0, 0]`	`[4, 0, 0, 0, 0]`	Failed
