The Log is the Agent: Event-Sourced Reactive Graphs for Auditable, Forkable Agentic Systems
Summary
The paper introduces ActiveGraph, an event-sourced runtime where an append-only log is the source of truth and a deterministic projection of that log forms the working graph. Agent behaviors react to graph changes and emit new events, enabling deterministic replay, cheap forking, and full lineage from high-level goals to individual model calls. With an open-source Apache-2.0 implementation and reproducible demos, the work offers a promising architecture for auditable and potentially self-improving AI agents.
