Member previewVariant 2 · 3 implementations · 8 checks per implementation

Case contract

Input [black_proposal, white_proposal] as lists of points (any order, duplicates allowed). Equal point sets -> ["agree", sorted points]; otherwise ["dispute", sorted symmetric difference].

Why this case matters

Go servers and scoring tools compute this value automatically; a wrong answer changes a game result.

One recorded failure

Sample boundary fixture

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