export type Model = {
  complete(input: ModelInput): Promise<ModelOutput>;
  stream(input: ModelInput): AsyncIterable<ModelToken>;
};

export type ModelInput = {
  prompt: string;
  frame?: GraphFrame;

StateWeave passes a serialized GraphFrame as prompt and the structured frame as frame. Provider adapters should stay thin and avoid leaking provider-specific concepts into the SDK surface.
