Architecture Overview

The current repository topology is:

flowchart LR
  Portal[apps/portal Astro] --> Docs[Starlight docs]
  Portal --> APIReference[Scalar API reference]
  ProductFrontend[frontend/vectorhub React Vite] --> API[backend1/Client Robyn API]
  ProductFrontend --> WS[WebSocket /ws]
  API --> MetadataDatabase[Gel / EdgeDB]
  API --> VectorStore[Qdrant]
  API --> Workdir[__workdir__ document files]
  API --> CloudAux[backend1/Cloud auxiliary backend]

backend1/Client is the main app backend. backend1/Cloud exists and is still relevant for cloud/embedding flows, but it is documented as auxiliary/experimental.
