The ledger
Every forecast, its timestamp, and its mark
Append-only. Every line is registered before the outcome is known and never edited afterwards. The ledger opens with the prison headroom track; the rest appear as they are registered.
Tracks 1. Lines registered 8. Resolved 0. Open 0. First mark expected 2 Oct 2026.

Each track opens onto its own lines, their benchmarks and the rule they will be scored by. Registered links to the commit that timestamped it. How the ledger works.
