### AI overview

The excerpt outlines a Go package design approach combining role-based authorization, API organization, and request handling. It describes using Rego scripts to define access rules based on roles and user IDs, separating exported functions from internal ones with a "double equal barrier," and using inline functions for tasks such as cache lookups. For errors, it recommends a consistent pattern for signaling issues, including authentication errors, to aid debugging. It also describes passing user claims through context from middleware to handlers, keeping business logic isolated from web-specific concerns. The excerpt provides no detailed code or full-document coverage.
