# Information Hiding

Record: `arch:information-hiding`
Kind: principle
Layer: [Structural Core](https://banes-lab.com/records/layer/structural-core.md)
Severity: mandatory
Scope: class, module, package
Canonical: https://banes-lab.com/ontology#arch-information-hiding

## Repair

- Refactored by: Introduce Facade, Hide Module, Restrict Exports
- Detected by: internal packages imported externally, exposed persistence models
- Violated by: exposing implementation details, shared internals
- Measured by: internal API exposure, dependency leakage
- Enforced by: package visibility, module export rules
