Concepts

Core ideas worth modelling before you write code. Each topic is self-contained — skim the one you need.

• Architecture — How the persona, the request enricher, ScaiMatrix, ScaiDrive, and the inference pipeline fit together.
• RAG strategies — Three retrieval strategies — single_step, multi_step, agentic — when to use each, and how source weights, top-k, and min-score interact.
