Automerge and Yjs

Automerge and Yjs are CRDT libraries. HyperToken uses Automerge underneath its Chronicle and adds game-oriented conventions: immutable Tokens, Stack/Source, Space, Engine dispatch, agents, rules, provenance, persistence, and optional network adapters.

Those abstractions are useful only when they match the domain. Use Automerge or Yjs directly for a general collaborative document, especially when their data types and ecosystem are a better fit. HyperToken does not replace either library; it is a domain layer with its own conflict and document-growth costs.
