How this case is scored.
Public summaries describe the task and rubric without exposing hidden ground truth. Judges are rubric-defined and calibrated quarterly. Custom scoring dimensions on this case reward chain-of-custody citations.

- Judges: deterministic, paired with rubric checks.
- Safety: 14 adversarial probes baseline.
- Efficiency: tokens + latency, normalised to baseline agent.
