## 1. System Overview
|
|||
|
|
|
|||
|
|
kontextual-engine is a **headless knowledge system** that enables persistent storage, transformation, retrieval, and AI-driven operation of structured and semi-structured knowledge across heterogeneous data sources.
|
|||
|
|
|
|||
|
|
This FRS defines the **externally observable functional behavior** of the system.
