# nemo_gym.verification

Helpers that resources servers share for verifying submissions.

judge calls an LLM judge and routes a failed judge call to the failures sidecar (`call_judge`,
`judge_failsafe`); verifier_fixture runs in-process contract tests of a server's verifier; and
sandbox_verification grades a submission in a fresh, single-use sandbox. sandbox_verification uses only the
provider-neutral API; core sandbox APIs and providers live in `nemo_gym.sandbox`.
