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.

Agents get guardrails, run credentials, an audit log, a context hub, repository instructions and mentions; security upkeep; snake_case API1//! Every response the REST routes give, run through the converter the API
2//! sends them with, checked for `camelCase` that would leak out.
3//!
4//! The samples are the reference's example responses, put back into the
5//! `camelCase` the services send (as serde's `rename_all` writes it) and,
6//! where an operation returns a contract type, decoded into that type and
7//! encoded again, so that every field the type has is sent, not only the
8//! ones an example shows.
