The DSL enforces validation and mapping rules at compile time, reducing runtime errors as emphasized in the key features and examples.

Supports chaining with and/or operators and methods like matchAny, allowing for readable, complex business logic without boilerplate code.

Provides a fluent API for data transformation between models with customizable converters, streamlining model-to-model conversions as shown in the mapping example.

Rules output plain text syntax trees via Readable#readable, aiding in debugging and documentation, as demonstrated in the syntax tree section.

Includes AssertJ-based assertions for validating rule behavior, making it easier to write and maintain tests for validation logic.
