Every public item, with its chain of custody

55 public items (corpus 2026.9). Each page shows the scenario, the quoted primary-source passages the key rests on, the derivation or the compute that produced it, the adversarial verification record — verifier models, verdicts, citations — and the version history. A further 28 items are held out and never published. Any public dispute is resolvable by inspection; see the challenge policy.
