The next object runtime moves from the private repository into pi: src/next (contracts, hosts and objects, documents, derives, links and relays, routines and jobs, the store) with its tests and examples in test/next, src/next-node (Node compression), and its design in docs/next (design.md, the decision log decisions.md, the slice plan slices.md, slice specs, books and benchmarks). AGENTS.md gets its code style. Not exported: the API changes with every slice until it has an entry point.
