1//! OpenAPI-based route generation for MockForge
2//!
3//! The authoritative `OpenApiRouteRegistry` and all `build_router_*` methods
4//! are defined in this file. Sub-modules provide additional utilities:
5//! - `builder`: Helper functions for building routers from specs
6//! - `generation`: Route generation utilities
7//! - `validation`: Request/response validation types and logic
8//!
9//! Note: `registry` sub-module contains an abandoned partial refactoring with a
10//! duplicate `OpenApiRouteRegistry` type. Use the one from this module.
