Field notes
YOINK adds frontmatter to ordinary Markdown notes so a claim can name its deadline, test, confidence, and data source. Its settlement command later records the source reading and outcome in the same file, while the vault view counts alive and dead notes, unresolved links, and due claims. The displayed demo contains 35 notes, 14 alive, 21 dead, and a Brier score of 0.388. The page also states that the $YOINK token is not live yet.
