Highlights

  • 741,000 rows split into train, validation, calibration, test, ood, and a 30,000-row test_set_30k.
  • Each row carries id, kind, options, target, state, question, domain, family, and source — targets are full distributions, not labels.
  • Kinds span the System One primitives with 2–16 options, across 66 domains and 14 families from fact-checking to multi-agent coordination.
  • Three source streams — yuri_v1, yuri_v3, and openjev_v2 — so provenance is traceable per row.

Watch out

The calibration split is a separate split for a reason: temperature fitting belongs on it, not on the test or ood rows. The corpus is training data for AutoTrust's students, not a benchmark, and some source rows repeat distributions at 0.5/0.5 where the teacher was uncertain.
