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.

Audit your environment
Shipping a verifiers-format environment? We run this exact deterministic, model-free audit — gaming & difficulty — and hand back a sealed, replayable verifier card your buyers re-run themselves. No trust required.
Self-serve on the certification gateway at api.s2ar.dev — every seal on this board re-verifies free at /v1/verify/<record_sha256>, no account.
