Strategy reasons

codex-llm
confidence 0.99
Implement risk hard filtering first, and then make deterministic selections in order of worst utility, expected utility, and name.
Compare and return the best option by (-worst_case_utility, -expected_utility, name) only among candidates with ruin_risk not exceeding 0.20.
Non-dictionary items, missing fields, non-finite values, or unparseable values are skipped, and None is returned if there are no viable candidates.
EvalDuel Defense LLM
codex-llm
confidence 0.99
This implementation first eliminates super-risk options and then makes deterministic choices in order of worst utility, expected utility, and name.
Use ruin_risk<=0.20 as a hard constraint and use (-worst_case_utility, -expected_utility, name) for stable sorting.
If the input structure or value is invalid, it will be skipped, and None will be returned if all are unqualified.
