Fix a detail, add a fact, or just confirm something’s still right. A change goes live once two neighbors confirm it — and you earn karma for keeping the guide fresh.

Add a fact and it’s pending until two neighbors confirm it (or one Steward) — then it goes live and you earn the points. Confirming earns +1 right away, and you can’t confirm your own. Explainers are one neighbor’s take, so they post right away. A fact’s stamp turns from green to amber as it ages, nudging a re-check.
