Time Travel And State Forking For Execution Replay And Branching

Build resilient language agents as graphs.

Unique: Provides first-class time travel and forking capabilities by treating execution history as queryable state, enabling developers to fork from any past checkpoint without manual state reconstruction. This architectural pattern is unique among agent frameworks and enables powerful debugging and experimentation workflows.

vs others: Enables execution replay and branching that imperative frameworks cannot support without external state management, and provides stronger debugging capabilities than frameworks without complete execution history.
