# Circuit Breaker Pattern

Record: `arch:circuit-breaker-pattern`
Kind: pattern
Layer: [Correctness Core](https://banes-lab.com/records/layer/correctness-core.md)
Severity: contextual
Scope: dependency call, service
Canonical: https://banes-lab.com/ontology#arch-circuit-breaker-pattern

## Repair

- Refactored by: Add Circuit Breaker
- Detected by: high failure dependency calls without breaker
- Violated by: continuing calls to failing dependency
- Measured by: breaker trip rate, downstream error rate
- Enforced by: [resilience policy](https://banes-lab.com/records/algo/resilience-policy.md)
