The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

AI-generated notes are less likely to be classified as helpful than those written by human experts, though they outperform those written by laypeople.

C2weakest assumption

The study assumes that the 20 identified AI writers are correctly distinguished from human writers and that the helpfulness ratings reflect genuine quality differences rather than biases in rater behavior or platform algorithms.

C3one line summary

AI writers account for 14.2% of Community Notes submissions with high responsiveness and coverage but lower helpfulness classification rates than human experts.
