## Repair

- Refactored by: Modularize Internally, Add Boundaries
- Detected by: cyclic packages, high global coupling
- Violated by: unclear internal boundaries
- Measured by: module boundary health
- Enforced by: modular monolith rules

## Requires

- [Unified Deployment Boundary](https://banes-lab.com/records/lexicon/unified-deployment-boundary.md)

## Reinforces

- [Operational Simplicity](https://banes-lab.com/records/lexicon/operational-simplicity.md)

## Enables

- [Transactional Simplicity](https://banes-lab.com/records/lexicon/transactional-simplicity.md)
