From the hub's dated sync history: new results as they are added, and SOTA stars as they are awarded or move.

This page ranks every result ChatPPG has recorded for sleep staging on walch-applewatch, measured by Cohen's kappa (sleep staging agreement). Alias: `kappa` (kept in Rank-axis / axis_id for slug stability; exporter canonicalizes to `cohen_kappa`) (lower is better). Each number is copied from the publication cited in its row, and ranks apply only within this dataset and metric and this protocol group.

Evaluation protocol: Apple Watch / consumer devices vs PSG
