Reward Integrity Index

Can an RL environment’s reward be satisfied without doing the task — and how hard is the task really? One deterministic instrument reads both, and you re-run every result byte-for-byte. No model in the loop to have a conflict of interest.

Don't trust us — re-run the seed.

Difficulty certificates

Model-free difficulty: how much search a fixed, seeded solver burns to reach a real solution, ranked against an independent oracle. Higher ρ = the certificate tracks true difficulty — the same searcher, the other end of the dial.

Delegation board

Which coding models we trust to delegate real work to: each model runs the same agentic tool loop over the same mined task bank (hidden tests, honesty audit), so honest-solve and cheat rates are comparable. Rank = spend per honestly solved task — the price of a unit of trustworthy work.
