# Environment Parity

Record: `arch:environment-parity`
Kind: principle
Layer: [Resource Core](https://banes-lab.com/records/layer/resource-core.md)
Severity: recommended
Scope: dev, test, staging, production
Canonical: https://banes-lab.com/ontology#arch-environment-parity

## Repair

- Refactored by: Containerize, Externalize Config, Use IaC
- Detected by: works-in-dev-only defects
- Violated by: environment-specific behavior not config-driven
- Measured by: [environment drift](https://banes-lab.com/records/lex/environment-drift.md)
- Enforced by: environment drift checks

## requires
