External reproduction #2: Ubuntu/Linux + Python 3.11

[weich97]

Goal

Run the TradeArena v0.2 no-key external reproduction pack on a fresh Linux environment with Python 3.11 and report whether the deterministic artifacts reproduce cleanly.

Target

• Repository: weich97/TradeArena
• Release tag: v0.2.0
• Expected path: outputs/reproduction/v0_2_external/manifest.json

Commands

git clone https://github.com/weich97/TradeArena.git
cd TradeArena
git checkout v0.2.0
python3.11 -m pip install -e ".[dev]"
python scripts/validate_benchmark_spec.py benchmarks/v0.2/spec.json
python scripts/run_external_reproduction_pack.py --output-dir outputs/reproduction/v0_2_external
python scripts/check_release_readiness.py

Acceptance Criteria

Please report:

• Linux distribution, kernel, CPU architecture, Python version, and install method.
• Commit/tag used and whether the working tree was clean before running.
• Full command log, including any failed command and traceback.
• outputs/reproduction/v0_2_external/manifest.json path and key fields.
• Benchmark spec canonical hash.
• Trajectory reproducibility hash and file SHA-256.
• Audit report, Agent Autopsy Dashboard, failure autopsy, and benchmark-row artifact hashes.
• Whether live APIs, downloaded market data, private fills, or broker data were used.
• Whether outputs/examples/audit_report.html and outputs/examples/agent_autopsy_dashboard.html opened successfully in a browser or via a local static-file preview.

Expected Reproduction Target

The no-key trajectory reproducibility hash should match:

sha256:bf3b1084aeec89f3bf0f99ab91b6c16a989dc8c8a29d9e93c8c72109548e442f

If it does not match, attach the manifest and logs so we can classify the drift.
