# Dependency Inversion Principle

Record: `arch:dependency-inversion`
Kind: principle
Layer: [Structural Core](https://banes-lab.com/records/layer/structural-core.md)
Severity: mandatory
Scope: module, component, layer
Aliases: DIP
Canonical: https://banes-lab.com/ontology#arch-dependency-inversion

## Repair

- Refactored by: Extract Interface, Introduce Port, Inject Dependency
- Detected by: dependency direction violations
- Violated by: domain importing infrastructure
- Measured by: inward dependency ratio
- Enforced by: dependency graph rules, architecture tests
