# Design Engineering Reference Profiles

Domain classification: design-engineering.

These experimental examples challenge the consumer-reference contract with intentionally different identities over the same pinned Layout source. They are related adversarial fixtures, not defaults, canonical guidance, production consumers, or independent adoption evidence.

## Routes

- [Governed Local Profiles](https://style.gallery/library/design-engineering/reference-profiles/governed-local/index/index.md) explains the two explicitly selected repository-owned examples.
- [External Adaptation](https://style.gallery/library/design-engineering/reference-profiles/external-adaptation/index/index.md) explains how external consumers retain their records without creating an in-repository adopter record.

## Ownership Boundary

Design Engineering owns profile identity and values. Consumer Reference validates shape and provenance without owning those values. Layout remains upstream and cannot import these records.
