## Repair

- Refactored by: Coordinate via Choreographed Events
- Detected by: a central coordinator coupled to all participants
- Violated by: one orchestrator commanding every step of a cross-service flow
- Measured by: orchestrator fan-out coupling
- Enforced by: [architecture review](https://banes-lab.com/records/arch/architecture-review.md)
