Reference

Specifications, roadmaps, and factual material that should stay stable across edits elsewhere.

Note

If a reference page here conflicts with newdocs/, follow newdocs/.
This Sphinx section is being incrementally reconciled with the canonical newdocs tree.

Start here if the book feels thin: Documentation coverage matrix lists every major subsystem, where the code lives, what is already written in legacy HTML, and what is still missing from Sphinx.
