# Model fallback decision tree drill brief

Use this brief to rehearse how the operating team responds when a model, provider, route, or policy gate fails. Fallback is not just a technical route; it includes owner decision, customer impact assessment, monitoring window, and return-to-normal criteria.

## Drill sequence

- Pick one trigger: outage, latency, quality, cost, policy, or incident.
- Activate the fallback route and record the owner decision.
- Confirm degraded behavior, logs, and customer impact.
- Decide when normal routing can resume.
