Building a Multi-Agent Brain Router: How We Unified 6 Business Units with Intent Classification and Supabase Memory

OPENING PARAGRAPH:
We built Luchin Jarvis OS—a unified agent orchestration layer that routes requests across 6 vertically integrated businesses (real estate, demolition, valet, credit repair, mineral rights, SaaS) using a central Brain Router with intent classification, TCPA-compliant policy gating, and persistent memory across Supabase. Here's the 9-file architecture we deployed on Vercel Flask: how we implemented lead entity resolution across lead_entities, lead_interactions, and strategy_memory tables; why we wrapped existing single-purpose agents into a tool registry instead of rebuilding; and what our weekly improvement loop looks like for refining classification accuracy. If you're scaling multiple conversational agents that need shared context, compliance guardrails, and deterministic routing—this is the pattern.
