In a single development session, we shipped three phases of a cognitive architecture that transforms Abby from a stateless RAG chatbot into a persistent, intelligent, context-aware research assistant. She now remembers who you are, routes complex questions to a more powerful brain, traverses clinical concept hierarchies, and warns you when your data has gaps. This post tells the complete story — the problems we solved, the architecture we built, and the engineering decisions behind 188 passing tests across 60+ new files.

Abby now has two brains. Simple queries stay local on MedGemma (fast, free). Complex reasoning escalates to Claude via API (powerful, cloud). A PHI sanitizer blocks any patient data from leaving the network, and a cost tracker with circuit breaker keeps spending within budget. Researchers get smarter answers on hard questions without compromising privacy or breaking the bank.
