# Development record Every feature cycle in this project produces a design spec and an implementation plan, both committed rather than thrown away, so you can read why the code looks the way it does — including the arguments that were considered and rejected. The roadmap — phases of feature cycles derived from the two-repo rewrite brief — and the current phase live in `ROADMAP.md` in this checkout. ```{toctree} :maxdepth: 1 :caption: Design record :glob: specs/* plans/* research/* ```
