Markdown content — everything under architecture/, agent-runtime/, api-protocol/, development/, frontend/, plugins/, product/, etc. This is what agents and humans read.
VitePress site — .vitepress/config.ts, package.json, package-lock.json. These drive the rendered documentation site.
Local preview
cd docs
npm install
npm run dev # preview on http://localhost:5173
npm run build # static build to docs/.vitepress/dist/
Conventions
New top-level docs must be linked from PLAN.md, README.md, and CLAUDE.md — otherwise agents can't find them (see .claude/ memory feedback_cross_reference_docs.md).
edit-history/YYYY-MM-DD.md is append-only log of significant changes; don't rewrite history.
archive/ holds one-shot analyses and retired docs — kept for context but not maintained.
Why site tooling lives here (not in docs-site/)
VitePress expects its config at <root>/.vitepress/config.ts where <root> is also the content directory. Splitting tooling into a sibling docs-site/ would require a non-trivial srcDir shim and break relative links in .vitepress/config.ts. Keeping both together is the pragmatic choice; this README is the tradeoff ledger.
