From question to verified answer — how Lawmadi OS works
Every legal query passes through a 4-stage pipeline to produce verified answers. Each stage has independent failure detection and recovery. If verification fails, the system blocks the answer (Fail-Closed policy).
NLU intent analysis assigns the optimal leader from 60 specialists while simultaneously searching Vertex AI Search and the statute cache for relevant laws and precedents. 3-tier routing classifies queries: greeting, non-legal, or legal.
Injects the assigned leader's core statutes (LAW_BOOST), links delegation clauses and enforcement decree forms via 3-tier comparison, and pre-fetches full article text from the DRF API to maximize accuracy.
Gemini 3.5 Flash generates answers via real-time SSE streaming, using the leader's persona and RAG context. Responses follow a 5-step framework: Empathize, Diagnose, Action Roadmap, Safety Net, and Closing.
Every statute, precedent, and constitutional court decision cited in the answer is cross-verified in real-time against Korea's National Law Information Center (law.go.kr) DRF API. If unverified citations exceed 0.1%, the answer is blocked. Verified corrections replace text in real-time.
Lawmadi OS is designed like an operating system with 8 independent layers, each performing a specialized role.
All answers are grounded in Korea's official legal databases (Single Source of Truth). Self-generated inference or fabrication is strictly prohibited.
