Status: Mature — This repository completed its growth generation (3 ticks) on 2026-06-13. Its successor is year-of-ai/2010 — the year 2010.
A self-growing knowledge base about the year 2009 — history, science, technology, arts, society, and people.
This repository is both a knowledge base and a reusable framework. It expands autonomously via /grow, which researches new on-topic content, builds structure, verifies facts, and publishes — all driven by the Concept Definition in seed.md. To retarget the framework at a different subject, run /genesis "<new concept>".
It is the successor instance in its lineage, spawned from year-of-ai/2008 — the year 2008.
