Run Experiment

Execute an existing Experiment Definition locally and finish with evidence from its canonical artifacts. Keep runtime readiness, regression testing, direct Policy Runner workflows, and managed submission outside this skill.

Read the checked-out documentation

Before composing a command, read:

• docs/pages/concepts/concept_arena_experiments.rst for Experiment structure and override rules.
• docs/pages/quickstart/arena_experiment.rst for the maintained local example.
• docs/pages/quickstart/environment_variations.rst when listing or applying variations.

Treat the current checkout as the source of truth. If this skill differs from the documentation or runner CLI, follow the checkout and report the mismatch.

Use typed YAML as the primary interface. Accept legacy JSON only as a pass-through compatibility path; do not create new legacy configurations or apply Hydra overrides to them.
