How it's built
Gemini on Vertex AI · Go backend on Cloud Run · Next.js frontend on Cloud RunRouterGemini 3.8 Flash
Checks which origin rules apply. Pharmaceutical and USMCA rulings go to their own rules; other questions outside substantial transformation go to a person.
Origin engineGemini 4 Argon
Reads the 5 most similar CBP rulings dated before the case date (BM25 over the public rulings) and predicts the origin CBP would likely assign, with its reasons.
Triage0.92 bar
At or above the bar the answer is auto-accepted; below it, it asks CBP-style questions and goes to review.
Plannersearch
Enumerates moves of operation groups between the plants you list and re-runs the engine on each.
Verifier agentGemini 4 Argon
For every move, searches for an earlier ruling that supports it and one that contradicts it. Only moves it supports past the bar are shown as plans.
Ask agentGemini · ADK
Answers questions about the case with tools to read the case and rulings, and re-runs the engine for what-ifs.
Product facts in, a broker-ready plan out: every answer cites the rulings it read, nothing reads rulings dated after the case, and a daily spend cap keeps model costs bounded. The engine, router and verifier are measured above; the held-out numbers use rulings the system never saw.
