NgRx state persistence de-serialization failure under production minification

When implementing a custom meta-reducer for state persistence, functional discrepancies often emerge between local development and production environments. While the local environment successfully hydrates the state from local storage, the production build frequently encounters runtime errors or inconsistent data during the initialization phase.

The issue appears linked to the aggressive minification and property mangling performed during production-grade builds. If the de-serialization logic relies on specific object keys that are altered during the build process, the meta-reducer fails to map the stored string back to the current state model. Furthermore, there is a lack of a native, built-in versioning schema for persisted objects, making it difficult to handle schema mismatches when a user returns to the app with stale data in their browser.

• How can developers ensure that serialized state keys are protected from property mangling without disabling minification?
• What is the recommended pattern for implementing partial state migrations within a meta-reducer when the schema evolves?
