SIMPLE humanoid evaluation

This integration follows the RoboDojo-derived service conventions. Its native humanoid controllers, 36-value commands and task scoring remain distinct.

The current v2 interface removes RSI's additional joint-target range rejection. It forwards finite physical targets through the original controller without clipping; native physics and controller limits remain unchanged. Optional model target guards belong in AgentPolicies/, not the SIM service. Frozen v1 records retain their old protocol and outcomes; see the action contract.

This benchmark can run as an independent SIM service via server.py. Start from server.example.json, adjust deployment paths/GPU before launch, and follow the shared server workflow. The server owns native reset/control/scoring; the evaluator uses the client, and the model receives only permitted observations. Native service-mode validation is separate from adapter availability.

The server excludes its episode-local cache/ from artifact transfer. The adapter assigns this directory to native runtime caches (including Omniverse texture caches and Torch extension builds); it is not rollout evidence. The exclusion is recorded in session receipts and the captured launcher. Native originals are retained, while observations, videos, logs, metrics and provenance remain exported. This affects new launches only: existing frozen runs keep their original inventories and cached files, without retroactive pruning.

SIMPLE is the whole-body humanoid benchmark from Physical Superintelligence Lab, not SimplerEnv or HumanoidBench. The simple_humanoid adapter connects a sensor-driven policy to G1's native AMO/SONIC whole-body controllers.

The released inventory has 12 tasks. The default campaign selects BendPickMP and OpenFaucetTeleop; explicit task_scope="released-12" selects all 12 once each. These are fast task selections, not the native domain-randomization/episode schedule. See task scope and EVALUATION_PROTOCOL.md.

The catalog is protocol data consumed by the service; native assets stay outside the package at configured deployment paths. bench_server/adapter.py delivers only the declared RGB/joint observations and translates public actions into the private worker protocol. native_worker_client.py launches and closes the pinned worker without defining tasks or model behavior. server.main(argv=None) uses the service-owned source inventory independently of campaign task selection. Model decisions and results stay in AgentPolicies/<profile>/. The catalog bytes, task/reset identities and protocol IDs are preserved when changing this directory layout. The public interface guide is reusable benchmark context. Historical reports, checklists and evidence caveats live in the anonymous code-agent results. The canonical adapter lives in bench_server/adapter.py; task selection lives beside the protocol in bench_server/protocol/plan.py.

Prepare the environment

The source pin is 5e3d6f84e85343e34e9bca8d157f0d7813231185, with Python 3.10, Isaac Sim 4.5 and MuJoCo 3.3.6. Native AMO/SONIC controllers and fixed locomotion weights are environment dependencies, not the high-level policy being evaluated.

Provision the upstream runtime, controller weights, robot assets, released evaluation metadata and referenced HSSD scenes under their respective licenses. environment/upstream.json records source, compatibility-patch, controller and asset-manifest requirements. simple_released_tasks.json binds task/backends and released resets.

A portable all-assets installer is not yet available. Installing RSI alone is insufficient. Adapter path defaults remain site-specific: explicitly pass simple_root and eval_root for a compatible local materialization. The worker uses <simple_root>/.venv/bin/python. Do not bypass source/asset checks to use a different release.

Run one task/backend per adapter. Check GPU capacity before initialization: controller contexts may appear on other visible GPUs, so choosing a renderer index is not complete isolation.

Check the integration

These inventory checks do not import a simulator:

PYTHONPATH=. python -B benchmarks/simBenchmarks/SIMPLE/checks/test_inventory.py -v
PYTHONPATH=. python -B benchmarks/simBenchmarks/SIMPLE/checks/test_instruction_contract.py -v
PYTHONPATH=. python -B benchmarks/simBenchmarks/SIMPLE/checks/test_server_launcher.py -v
PYTHONPATH=. python -B benchmarks/simBenchmarks/SIMPLE/checks/verify_inventory.py \
  --inventory benchmarks/simBenchmarks/SIMPLE/bench_server/protocol/simple_released_tasks.json

Run checks/test_boundary.py in the pinned native environment for runtime-dependent checks. environment/diagnose.py performs reset, stabilization, rendering and one measured hold with zero policy calls. Its CLI currently uses site-specific adapter path defaults and the two default task identities; a relocated deployment must use explicit adapter paths in evaluator-owned diagnostic setup. Diagnostic measurements are not a policy feature or capability score.

Evaluate one selected task

Configure the paths and one task in a local copy of server.example.json. Set the evaluator-only token following the shared server workflow, then launch the stable entrypoint with a fresh result directory:

python -B -m benchmarks.simBenchmarks.SIMPLE.server \
  --parameters /absolute/simple-server.json \
  --seed 20260907 --episodes 1 --port 8765 \
  --output-dir /absolute/model-results/simple_humanoid/new-run/server

The server starts without resetting the simulator. A trusted model-owned driver connects to the declared schedule and performs the single reset/attempt. Its policy receives the permitted observation/action interface, without the service credential or private score/reset metadata. Keep client records beside server records in the selected model's results namespace. Native full-mode support is not implied by this service entrypoint.

For the model-owned native-vector driver, follow NATIVE_CONTROL.md. See the evaluation workflow for source capture and closed-record reporting.

The selection plan freezes preselected tasks; its launcher also requires deployment-compatible runtime paths. Retain each task's single outcome, including failures and environment errors. Full native episode/DR coverage and a portable asset bootstrap remain unsupported.
