  • recommendations.jsonl: every comment counted as a recommendation. Comment id, author, date, target item, label (rec, aged_well, aged_poorly), strength 1–3, verbatim quote, and the comment’s HTML as HN serves it.
  • labels.csv: the classifier’s verdict on all 41,033 candidate links, including the ones it rejected.
  • links.csv: all 397,309 comment→HN item links we found, with the rule that dropped each one (if any).
