One deterministic game contract for human play, agent evaluation, and independent verification of exact runs.
As agents and world models move from answering questions to acting over time, evaluation needs environments where decisions change what happens next. Games make planning, adaptation, memory, cooperation, and failure visible inside a controlled world.
A Game-as-a-Benchmark product is both playable and measurable. People and agents reach the same versioned rules; scores summarize performance; portable evidence preserves how each result was produced.
Use one product reducer for the renderer, authoritative host, bots, tournaments, and replay. Compose reusable mechanisms without surrendering your rules, content, presentation, or commercial policy.
Build your first game →Expose structured observations and legal actions, evaluate single or multiple agents, and publish the result with evidence of the exact run. You retain task design, score meaning, held-out content, and claims.
Build an evaluation →Reproducing an evaluation repeats its inference cost and produces a new stochastic sample. It does not check the published run.
GAOS preserves canonical reducer inputs, results, signatures, and chains so an independent verifier can re-simulate the exact recorded run:

independent verificationGAOS makes the historical verifier portable as a product-owned, content-addressed kit. GAOS checks and executes the kit; the product preserves and publishes it; an independent manifest, catalog, or allowlist authorizes its digest. If required verifier material is unavailable, the result is unverifiable—not silently trusted. v1.0 freezes that evidence contract while keeping product-specific hosted adapters outside the standard SDK.
