TL;DR — I ran a personal wiki inside Claude Code for a month and shipped it as Hypomnema (npm install -g hypomnema). It's MIT, plain markdown + git, no vector DB, no API keys. The core is 14 lifecycle hooks that wire the wiki into Claude Code so it maintains itself — auto-commit, auto-push, session-state injection, lookup signals, compact-time guards. The most acute thing a month of dogfooding surfaced — AI behavior corrections rotting across three hand-synced storage layers — gets a fix that ships with this first drop. This is the field report.
