Relurpic Internals
The maintainer's book: walk the building itself — the machine-checked architecture, the governance engine, the sandbox, and the knowledge substrate.
Book 2, for potential contributors and maintainers. Book 1 put you in the kitchen; this one walks you into the building. The blueprint checks itself: fifteen domains, the direction of every import, and the split between the two special directories are machine-checked law, not convention. By the last chapter you will have opened a pull request that passes every gate.
