# The knowledge hub

> The knowledge hub is the organizational memory Cerebrum's agents draw on. Every answer is grounded here.

## What lives in it

* Hand-written documents.
* Imported content from your team's existing tools (with the right connector).
* Synthesized rollups — Q\&A pairs, retrospectives, summaries.
* Agent diary entries — decisions and reasoning captured as work happens.

## How it's organized

Every document has a *scope* — a path like `cerebrum/components/worker` or `your-project/overview`. Scopes form a tree: the first segment is a domain (a product, a project, a topic), and deeper segments narrow down within that domain.

Agents filter retrieval by scope prefix. Asking for context "under `cerebrum/`" returns only Cerebrum-scoped documents. Asking under another project's scope returns only that project's content.

## How retrieval works

Documents are chunked by heading and embedded into a vector database. When an agent needs context, the platform pulls the most relevant chunks — filtered by sensitivity tier, scope, and time — and includes them in the prompt with citations back to source documents.

## How content stays current

* **Manual edits** through the admin surface. Edits sync to the search index within about a minute.
* **Connector pulls** that sync from your team's other systems on a schedule.
* **Agent diaries** that capture decisions automatically as workers execute jobs.

Once a document is in the hub, every agent's next answer can use it.
