OpenFOAM OSWorld Benchmark

This gated dataset contains OSWorld-style, long-horizon OpenFOAM and ParaView tasks. Each release task combines deterministic CFD evidence and engineering decision criteria with a substantive native ParaView state and scientific image deliverable. CLI assistance is allowed, but the final GUI evidence is graded.

Current release tasks

The current five-task set is:

1. of_battery_coldplate_release_review_v4
2. of_fda_nozzle_re5000_validation_review_v4
3. of_hvac_thermal_comfort_acceptance_v1
4. of_porous_barrier_transient_assessment_v1
5. of_edge_compute_thermal_qualification_v1

Task definitions are in harness/tasks/; matching guest assets are in harness/assets/. The task JSON contains the locked SHA-256 for its asset.

The other task JSON and asset versions are retained as reproducible benchmark history. They are not current release candidates. The rejected/ directory is an explicitly withdrawn evaluator experiment and must not be used as a task.

Repository layout

• harness/tasks/: OSWorld-style task JSON files.
• harness/assets/: guest-visible task assets.
• intermediate_design/: bilingual review-stage scenario and GT-policy materials; these are maintainer documents, not agent-visible task inputs.
• reference_private/: answer-side GT, deterministic oracles, source snapshots, asset builders, and task generators. Do not expose this directory to an agent during an evaluation run.
• audit.py: rebuild, evaluator-replay, leakage, PNG-contract, and lint audit.
• HANDOFF.md: detailed version history and harness handoff notes.
• rejected/: withdrawn research artifacts, clearly separated from releases.

Evaluation boundary

During a benchmark run, the agent should receive only the selected task JSON, its matching asset, and the configured VM snapshot. reference_private/ is included in this repository because it is needed by benchmark maintainers to audit exact answers and regenerate artifacts; it is not guest input.

The instructions shown to agents are intentionally concise. Physical definitions, acceptance thresholds, and blank deliverable templates are stored inside each task asset. Method tutorials, command sequences, and answer values are excluded from guest-visible assets.

Answer-isolated public trial

public_trial/ is the safe solver-facing distribution. It contains sanitized task JSON files and the complete matching guest assets, but no evaluator, expected values, private GT, oracle, score code, or answer-side source snapshot. The directory is also available as public_trial/Openfoam-Osworld_Benchmark-public-trial.tgz for direct distribution. See public_trial/manifest.json for locked file hashes and guest deliverables.

Current edge-compute correction

of_edge_compute_thermal_qualification_v1 uses net_exhaust_mass_flow_kg_per_s, defined as the signed face-flux sum with net outward flow positive. Its state evaluator accepts native ParaView files where ServerManagerState is bare or wrapped by GenericParaViewApplication or ParaView.

Validation

From the repository root in the original Orion workspace:

/diskarray/home/tl688/orion/envs/orion/bin/python codex/openfoam/claude_handoff/audit.py

The audit verifies task/evaluator array consistency, generated JSON parity, asset hashes, deterministic GT replay, perfect-submission scoring, neutral identifiers, tutorial and answer leakage, native-state contracts, full PNG decoding, adversarial blank/missing-panel rejection, and the harness's actual score.py lint.

Licensing note

The benchmark bundle contains derived and frozen evidence from multiple scientific sources and OpenFOAM tutorial material. Consult the provenance in the private builders and the applicable upstream licenses before redistribution or commercial use. The repository metadata therefore uses license: other rather than asserting a single license for every artifact.
