What it is
A real-time risk triage gateway for crypto exchange deposits and withdrawals. It screens each transfer event using Jev for triage while deterministic Java code makes the final decision. For developers building exchange risk systems.
How it uses Jev
Jev answers four typed questions per transfer: risk_level (score), pattern (choice), should_freeze (noul), and route (observation only). The answers are used by Java GateLogic with pFreeze, cHigh, cLow, and highRiskOrdinal to compose the final action (auto-pass, manual review, or freeze).

Technique worth stealing
Keep composition in code: Jev triages, deterministic code decides, with hard-rule veto and degrade to manual review.
Try it
Requires JDK 17+ and Maven. Run `mvn spring-boot:run` then `./demo.sh` for mock mode.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
