Types and State Serialization

Connection types are number, boolean, string, event, widget, and table. Connections require exactly matching types and each input accepts at most one edge.

Persistent values support Lua nil, booleans, finite numbers, strings, and acyclic tables. Table keys must be strings or integers. The maximum table depth is 16 and all program data shares the four-megabyte limit.

Functions, userdata, threads, cyclic tables, non-finite numbers, fractional numeric keys, and unsupported Java values are rejected. A serialization failure fails only the invocation and preserves the last committed state and outputs.

State is copied into an invocation. ctx:set_state stages a replacement; successful callback return commits the entire staged map. Yielded callbacks keep staged changes private until resumption completes.
