Interface

A boundary or contract between system components that defines how they communicate, exchange data, and interact. Interfaces abstract implementation details to enable modular system design, appearing across domains as REST APIs, smart contract ABIs, ROS topics, rendering APIs, and chat APIs. Interface design governs versioning, error handling, and protocol compliance.
