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.

Issues and pull requests replace intents and attempts1//! The work service: issues, pull requests, comments and sessions.
Work service in Rust, with RFC 3339 timestamps2//!
3//! Other services reach it over `POST /rpc/<method>`; see
4//! `g1t_contracts::work` for the methods and their arguments. It also
5//! consumes its queue of events from the bus.
