Module 4: A deep dive into the code

So far you have watched the full pipeline run end to end: preprocessing, embedding, uploading, and searching vector data and metadata on-chain.

This module takes you inside the architecture and implementation. You will see how the Rell backend connects to the Vector DB extension, how complete movie metadata is kept next to the vectors, and how the Python client communicates with your Chromia chain.

You will step through the same code the demo runs. Along the way, the lessons point out where the design is flexible, so you can adapt it to your own use case.
