# Facade Pattern

Record: `arch:facade-pattern`
Kind: pattern
Layer: [Design Patterns Core](https://banes-lab.com/records/layer/design-patterns-core.md)
Severity: recommended
Scope: module, subsystem, API
Canonical: https://banes-lab.com/ontology#arch-facade-pattern

## Repair

- Refactored by: Introduce Facade
- Detected by: broad dependency surface to subsystem
- Violated by: consumers depending on many subsystem internals
- Measured by: consumer dependency count
- Enforced by: API boundary rules
