"""Open-ended Working Leo benchmark.

The precise live canaries intentionally pin exact IDs. This benchmark tests the
harder Cory-style behavior: vague operator prompts where Leo must infer that the
real issue is proposed/approved/applied DB state, ask or query for evidence,
avoid overclaiming, and give the next safe action.

By default this script only prints the benchmark spec. Use ``--url`` to send the
read-only prompts to a chat endpoint. The scorer is heuristic by design: it is a
guardrail for broad regressions, not a replacement for row-level DB proof.
