Summary by CodeRabbit

  • New Features

    • Native-v1 and wheels-v1 Gym environments are now supported.
    • Environment packages can provide agent and resource-server components, with automatic selection and configuration.
    • Agent configuration is optional when supplied by the environment package and serves as a fallback otherwise.
    • Gym execution profiles can use subprocess-based execution where supported.
  • Bug Fixes

    • Added validation for duplicate or conflicting component names.
    • Improved validation messages for invalid environment packages and FileSet references.
    • Prevented unsupported customer model declarations in environment packages.

📝 Walkthrough

Walkthrough

Native-v1 Gym packages now pass submission and runtime validation. The system inspects components, validates namespaces, composes Gym configuration, supports package-provided components with fallbacks, and selects subprocess execution profiles for Gym staging and evaluation.

Changes

Native Gym environment support

Layer / File(s) Summary
Package inspection and namespace validation
packages/sandboxed_gym/src/sandboxed_gym/environment_package.py, packages/sandboxed_gym/tests/fixtures/native_v1_custom_environment/*, packages/sandboxed_gym/tests/test_environment_package.py
Native-v1 packages are accepted. Component declarations and namespaces are inspected. Duplicate and cross-type names are rejected.
Evaluator target and sandbox configuration
plugins/nemo-evaluator/openapi/openapi.yaml, plugins/nemo-evaluator/src/nemo_evaluator/jobs/{agent_spec.py,gym_environment_package.py,gym_sandbox.py,environment_stage.py,agent_evaluate.py}, plugins/nemo-evaluator/tests/test_gym_environment_package.py, plugins/nemo-evaluator/tests/test_gym_sandbox.py
Environment-backed targets accept native-v1 packages. agent_config becomes conditional, and component-selection metadata provides package and fallback configuration paths.
Environment package composition and bootstrap
packages/sandboxed_gym/src/sandboxed_gym/runtime/gym_host_runtime.py, packages/sandboxed_gym/tests/test_gym_host_runtime.py
The Gym host validates selections, prepends package discovery roots, composes configuration paths, and configures the package before wheel installation and Gym import.
Execution profile selection and subprocess compilation
plugins/nemo-evaluator/src/nemo_evaluator/jobs/{agent_evaluate.py,agent_compiler.py}, plugins/nemo-evaluator/tests/test_agent_evaluate.py
Gym compilation resolves execution profiles and uses subprocess providers for staging and evaluation when selected.

Merge Risk: 🟡 Moderate · up to 1e69a

Gym evaluation compilation may validate storage against the wrong execution provider when duplicate non-subprocess profile names exist, potentially rejecting valid jobs or allowing jobs that later fail staging. Resolve provider-specific fallback selection before merge.

Resolve the fallback profile by provider.

When multiple non-subprocess profiles share a name, line 398 can select a provider different from the emitted cpu executor. The storage check can then use the wrong PVC configuration. Filter the profile by provider before calling require_fileset_sandbox_storage_identity.
