Pets Governance — Council by Bloc STAR (3 seats): majority sweeps¶

Generated from pets_gov_bloc_star.yaml — do not edit by hand. Regenerate: python STARVote_LH_tabulation_engine/tools_adam/scripts/build_yaml_pages.py.

Method: Bloc STAR (multi-winner, majoritarian) · 3 seats · Expected winners: Dog, Fish, Cat

Scenario¶

One of six races in the Pets Governance election (BV2134, bvid kcf8vf; BV-confirmed). 22 voters split into a 13-voter MAJORITY ("Furries": Dog, Cat, Fish) and a 9-voter MINORITY ("Others": Bird, Rabbit, Hamster). This race fills a 3-seat Council by Bloc STAR — a MAJORITARIAN method. The majority's top three sweep every seat: Dog, Fish, Cat. The minority gets nothing. Contrast with the STAR-PR and STV races on the same ballots, where the minority earns a seat (proportional).

Ballots¶

Row 1 = candidate names; each later row is one voter's 0–5 scores (a N × prefix = N identical ballots).

Dog,Cat,Fish,Bird,Rabbit,Hamster
13: 5,4,4,1,0,0
9: 0,0,1,5,4,4
