The core idea for yoagent-state comes from Yohei Nakajima and his ActiveGraph work.

This project is an independent Rust implementation inspired by that idea. It keeps the architecture small for yoagent and yoyo evolve, while preserving the important ActiveGraph-style primitives: append-only events, replayed graph projection, goals, tasks, observations, hypotheses, patches, artifacts, evals, decisions, policies, behaviors, packs, replay, and forks.

The guiding boundary is:

Git stores what changed.
yoagent-state stores why it changed, what tested it, and what it means.
