  "what_this_is": "The statements a SAMPLE CANNOT ESTABLISH, published separately and signed with the same key that signs TRUST-ROOTS.json. A subset proves nothing about its superset, so coverage, denominators and precision are attested here rather than implied by a sample.",
  "what_the_interval_does_not_cover": "The intervals above are Wilson bounds on sampling error, given the denominator. Two things they do not describe. FIRST, records the verifier could not decide are excluded from the denominator rather than counted against it, so precision is measured over the records this instrument could read \u2014 the `sampled`, `confirmed`, `contradicted` and `inconclusive` counts are all published so you can recompute it either way. SECOND, an interval assumes the draw is fixed. Ours is: the sample is drawn deterministically and three consecutive runs of the instrument produced byte-identical verdicts on every stratum and every drawn record. Before 2026-09-17 that was not true, and figures published earlier are historical readings that cannot be re-derived.",
