Pinned environment and command

• Python requirement: exactly 3.12.x
• Resolver and runner: uv
• Lockfile: uv.lock
• Scientific dependency: numpy==2.3.2
• Fixed command: uv sync --frozen && uv run python repro/src/run_logdiff.py --output-dir .openresearch/artifacts --seeds 25
• Baseline compute estimate: one CPU core, under five minutes
• Baseline backend policy: local, supervised through orx exp run

The run log records the branch Git SHA, actual visible CPU allocation, Python and NumPy versions, deterministic seed list, and wall-clock runtime.
