Claim labels
Official means a primary publisher, platform or developer source states the fact. Preview-verified means a named outlet reports observing it in a preview build. Guide-credited means the answer comes from a named, published walkthrough. Editorial means the page describes this site's method or recommendation.
Puzzle solutions
A solution is published when a named outlet has documented it, and it is shown at the top of the page. The page credits that outlet. When two walkthroughs disagree, both readings are shown. If a patch changes a step, the page says which patch, and the change is dated in the update log.
Corrections
Material errors are corrected with a dated update note. Missing data is treated as unknown, never as zero, absent or impossible.
