Safety

Flags are raised by the gym and the scenarios while a run plays: crimes by the agent's resident, actions refused by policy, invariant failures, and anything a scenario detects (collusion, deception). Financial distress (rent notices, missed loan payments, insolvency) is shown separately: it is a capability failure, not misconduct. Rates are per agent-episode on the ranked scenarios.
