Olympics reasoning traces, one per source row
Distilled from pranjalvoid/olympics-dataset
(athlete_events.csv, 120 years of Olympic entries). 269,723 of the 269,731 unique source rows (after dropping exact duplicates) have exactly one row here (99.997%; the 8 rows without a verified trace, source_row_index 2548, 26869, 85768, 130197, 131601, 201327, 251048, 257739, are counting questions over 100+-entrant rosters that no sample answered correctly across 3 question templates and 60+ samples per row). Each row is a verifiable question anchored on
one entry (athlete, event, Games), the gold answer computed from the data, and a verified-correct reasoning trace.
Traces were generated by nvidia/NVIDIA-Nemotron-3.5-Lightning-30B-A3B-BF16 served with NVIDIA Dynamo 1.5.1 (SGLang backend) on
GB200 nodes: several samples per question (T=1.0, top_p=0.95, reasoning on); the shortest trace whose final answer
matches the gold answer was kept. Each prompt contains the relevant table (the event's entry list at that Games,
or the athlete's career record), so the answer is fully determined by the prompt.
