# Self-Healing Architecture

> The ability of a system to detect a failed component from its health signals and restore it without human action.

Listed in [Architecture principles](https://banes-lab.com/api/records/architecture.md), after [Feature Toggle](https://banes-lab.com/records/architecture/feature-toggle.md) and before [Health Checks](https://banes-lab.com/records/architecture/health-checks.md).

## Repair

- Refactored by: Add Health Checks, Add Restart/Remediation Policy
- Detected by: recurring manual recovery steps
- Violated by: detectable failure without automated remediation
- Measured by: MTTR, auto-recovery success
- Enforced by: orchestration policy, runbooks
