| simulate_scenario | What-if Monte Carlo: modeled expected premium vs refund/loss over a horizon. |
| check_swap | Pre-trade check an agent runs before it signs: modeled route quality, price-impact / slippage band, modeled MEV/execution exposure where observable, and a… |
| get_preflight_record | Fetch one persisted preflight evidence record by record_id (owner-scoped to the configured key's account). The record embeds the original check response… |
