## Summary

Three kinds of context, three write rules, and a project that outlives the session, the harness, the model and the machine

## Overview

The Curator — the context engine. Your brain. Your team’s brain. Your agents’ brain. A local app that turns what you read into a compounding wiki, shares it with a cohort, and holds your projects’ context — foundations, working state and knowledge — so any agent, in any harness, resumes where the last one stopped. Plain markdown, in your own repo.
