Cast Sense — source-grounded coaching product
A coaching product that answers from a curated source library and live environmental conditions instead of from a model’s memory. Sources are embedded and retrieved with pgvector; answers cite what they came from; and when the sources are thin the product says so instead of inventing something that sounds right.
This is the reference build for the Scalable Infrastructure pillar. Everything I would put in a client RAG pipeline is running here first, on my own budget.
