# Memory & Knowledge Workflow

> Store durable user memory and search saved knowledge.

Memory routes manage durable facts and preferences:

```http theme={null}
GET /api/v1/memory
POST /api/v1/memory
PATCH /api/v1/memory
DELETE /api/v1/memory
```

Knowledge search uses:

```http theme={null}
POST /api/v1/knowledge/search
```

Knowledge search may combine uploaded files, memory, notes, projects, and indexed document content depending on active capabilities and user state.

When vector search is disabled, route behavior should remain deterministic and avoid crashing the app shell.
