## Summary

A follow-up seven weeks after the Shared Brain launch. The author's own wiki has 3,305 nodes and 15,095 edges at v3.0.6.

## Overview

The road from a single idea in a GitHub gist to a knowledge system two chapters deep: a personal Second Brain that has been stable since April, and a Shared Brain that just came through five structured hardening phases and is waiting on the one test that matters most. This article picks up directly where “The Shared Brain: When Second Brains Start Thinking Together” left off.
