What problem does it solve?

Type-driven domain modeling reduces runtime errors by representing domain invariants as compile-time guarantees and unrepresentable invalid states.

Core Features & Use Cases

• Domain wrappers for primitives to prevent confusion and enforce boundaries
• Validated construction (smart constructors) to guarantee invariants
• Workflows as functions and state machines to model lifecycles
• Type-level error handling and bounded contexts to reduce runtime checks

Quick Start

Create a domain model by wrapping a primitive, implement a smart constructor with validation, and compose it into a type-safe workflow.
