Elixir implementation of the A2UI protocol core engine: versioned message envelopes, catalog schemas, surface state, data model, and processing of agent-to-renderer updates.

The modules are layered:

• primitives: A2UICore.Version, A2UICore.Pointer, A2UICore.Identifier, A2UICore.Error;
• wire: A2UICore.Message and the operations it decodes to;
• schema validation: A2UICore.Schema;
• state: A2UICore.State.Surface, A2UICore.State.DataModel;
• catalogs: A2UICore.Catalog, A2UICore.Catalog.Basic;
• resolution: A2UICore.Resolution.NodeResolver, A2UICore.Resolution.DataContext;
• processing: A2UICore.Processor;
• function calls: A2UICore.RPC.

Start with A2UICore.Processor and the processing guide.
