License & attribution

Code is MIT, but problem statements are copyrighted competitive-programming content — we ingest scores only, never problems. Leaderboard JSONs are unlicensed facts, attributed and linked.

What we ingest

Per-problem pass@1 records from performances_generation.json, aggregated over contamination windows (v5/v6 vintages kept separate). The project has been dormant since 2025-08 — held for historical value; fresh coding signal arrives via other sources.

partial = run finished but some rows are blocked on identity review — nothing is published until every referenced model/agent/benchmark is resolved.

Snapshots are immutable raw payloads — every published number traces back to one. Re-fetching an identical payload bumps the re-fetch time instead of storing a duplicate. Scores from this source appear on benchmark profiles and model pages with this source linked.
