- References are Ref<C> (was Handle<C>), objects ObjectImpl (record.ts is object.ts), ImplementationOf<C> (was
BehaviorOf<C>), ResourceDeclaration (was ResourceSpec); epochs are code versions (codeVersion in Ctx, RootOptions,
Shape, Host, frames and reload reports). Docs say object and reference.
- A remote object's variant is named variant (was kind): factories return { variant }, references expose ref.variant.
- Links announce a protocol version (PROTOCOL_VERSION = 2) in hello; peers of different versions close the link with
reason protocol-version <n> and report it through LinkOptions.onProtocolMismatch.
- ServeOptions.lifetime ("referenced" | "host") replaces eager: a host-lifetime object is local, has an empty input,
exists once per host and lives until the host closes; awaitEager is awaitHostObjects. A reload that makes a type
referenced releases the host's own reference.
Replace the alternate tracker implementations with the optimized immutable overlay, validate draft placements as strict JSON, and document the ownership contract. Consolidate tracker tests and benchmarks around the canonical implementation.
