DvalinCode vs NeMo Guardrails

DvalinCode leads on trust: 83.6/100 (Grade A) against 74.7/100 (Grade B), a 8.9-point gap. DvalinCode leads on supply-chain integrity and provenance; NeMo Guardrails leads on maintenance and adoption, and rests on broader evidence. Note: DvalinCode's evidence coverage is thinner (coverage B vs A) — its score rests on fewer independent signal types.

How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption, scaled by an evidence-confidence factor. Grade bands: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Signals refresh daily. Full methodology v4.4 →
