Schema helpers are a thin layer over pi-schema's builders with the same JSON,
so fingerprints and stored data are unchanged (proven by schema-switch tests and
a store written by the TypeBox code). Checks through pi-schema; error messages
are pi-schema's; format is an annotation. v1 contracts take any JSON Schema.
map(bytes()) works.
The contract field placement is hostAddress, required on every remote() (type and declaration error); the
fallback for remote types without one is gone. invalid/placement is invalid/host_address. host/placement.ts
(Placement) is host/destination.ts (Destination); here is decided by address alone, and a host without an
address refuses to serve a remote type. A hold always carries its address on the wire (the binary codec's
ADDRESS flag is gone, the text codec requires it). Tests and examples declare their host addresses.
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.
