brain/knowledge/index.md
Durable context for this repo. Every folder here is a page in Craftspace, and every page here is a file in the repo, so the team reads the same thing whether they open GitHub or the app.
This page is a spine: one line per Area, pointing at the page that holds it. Hard-to-reverse calls live as Decisions, not here.
Add one folder per Area that fits what this project actually holds — an engineering project grows different
ones than a sales project does. decisions/ is the only one every repo starts with. Replace these examples
with your own and keep the shape: bold name, then the one line that says what a reader will find there.
One Area owns exactly one page, and that page is a glossary spine: one line per term, defining what the term IS. A term that outgrows its line graduates to its own file beside the page. Search before you write — a second page for an Area that already has one is the failure this structure exists to prevent.
<area>/index.md is the page for <area>; a file beside it is that page's child.
