Pick any line to see why it is the way it is: the commit, the pull request and issue it came from, and what the agent was thinking.

API and MCP server, Rust identity service, registration, site redesign1//! Types and service interfaces shared by every g1t service.

3//! Each service has a module here holding the data it exchanges and the
4//! arguments of each of its methods. Services and their callers depend on
5//! this crate, never on each other's code.
