Active / Shadow loops
Two evaluation paths support controlled comparison before a model or retrieval configuration is promoted.
EXPERIMENTAL LEGAL AI LAB
NEXUS TwinLoop Legal Lab v3.3
A laboratory prototype for testing retrieval quality, unsupported claims, jurisdiction boundaries, service limitations, and high-risk legal scenarios.
STATUS: LAB PROTOTYPESOURCE GUARD: ACTIVEPRODUCTION: NO
Architecture
Source-controlled generation
The prototype is designed to answer from retrieved material and return an unverified state when support is insufficient.
Jurisdiction detection
The system checks whether a relevant jurisdiction has been identified before allowing jurisdiction-specific conclusions.
Boundary detection
Requests involving representation, filing, guaranteed outcomes, or unsupported professional services are detected and refused.
Current test metrics
Unsupported claim rate
Service-boundary refusal rate
Jurisdiction-boundary rate
Out-of-scope refusal rate
Legal detection accuracy
Retrieval coverage rate
This laboratory prototype is not a legal service, does not provide legal representation, and is not ready for production use.
