# Composability

Record: `arch:composability`
Kind: principle
Layer: [Structural Core](https://banes-lab.com/records/layer/structural-core.md)
Severity: recommended
Scope: function, component, system
Canonical: https://banes-lab.com/ontology#arch-composability

## Repair

- Refactored by: Normalize Interface, Extract Component, Introduce Adapter
- Detected by: non-chainable APIs, incompatible contracts
- Violated by: [hidden side effects](https://banes-lab.com/records/lex/hidden-side-effects.md), [incompatible interfaces](https://banes-lab.com/records/lex/incompatible-interfaces.md)
- Measured by: composition count, interface compatibility
- Enforced by: contract tests, type checks
