Structuring domain modeling in Laravel involves defining a PSR-4 layout under app/Domains to separate core entities like Person, Context, Cycle, and Evidence from infrastructure concerns, ensuring sustainable architecture.

In domain-driven design, an Eloquent model typically represents a persistable entity with identity, whereas a value object is an immutable concept without identity. This Skill specifies which domain objects like Evidence should be Eloquent models versus value objects.

You should use a derived projection like 9BOX in domain modeling when you need to calculate performance management outcomes from immutable facts. The 9BOX serves as a projection derived from core entities rather than being a primary domain object itself.

You should not use Eloquent models for all domain entities in Laravel. This approach clarifies which specific domain objects like Evidence should be Eloquent models versus value objects to maintain clear domain boundaries and enforce DDD principles.

The best way to separate domain logic from UI concerns in Laravel is to model domain concepts within an app/Domains structure using DDD principles, providing a clear path for services and repositories while keeping UI and infrastructure concerns out of the domain model.
