Type Alias TypeId 

pub type TypeId = String;

Stable, language-independent identifier for a named type definition. Must be unique within the enclosing schema-graph. Conventional format is a dot-separated namespace path (e.g., "myapp.users.user"). Each SDK provides a default derivation rule (typically based on the local language’s type name); cross-language interop requires the same type-id on every side, which users can pin via the SDK’s named attribute.
