EvidencePath Auditor
A governance dashboard that catches silent 'evidence drift' in enterprise AI used for document, contract, and claims analysis — flagging when a retrained model starts citing different passages, charts, or pages than its previous version even when the final answers still look correct.
AI governance, legal ops, and internal audit teams overseeing document-analysis AI
- Frozen-baseline regression suite that re-runs a curated library of document queries against both old and new model versions
- Channel-level diff that shows whether the new model relies more on text vs. tables vs. OCR vs. figures to reach the same answer
- Pre-deployment gate that blocks a model update if grounding drift exceeds an org-defined threshold
- Audit-ready report exporting evidence-channel shifts per query for regulators and internal review boards
The paper formalizes a failure mode most enterprises don't even know to test for, and as companies rapidly retrain or swap AI assistants this hidden drift is becoming a real legal and compliance liability.
Multiple recent articles, comparisons, and frameworks address AI model drift and governance; Stanford/RAG hallucination papers and legal RAG tools signal real enterprise concern about grounding shifts.6 Model Monitoring and Drift Detection Software Tools That Protect AI Accuracy ↗Hallucination-Free?

General-purpose AI monitoring/governance platforms (Arize, Fiddler, Arthur, Monitaur, Credo AI, Holistic AI) dominate; only academic/single-purpose prototypes like HalluGraph target evidence/citation grounding in legal RAG, leaving a narrow but contested niche.6 Best AI Governance Tools in 2026 - TextCortex ↗HalluGraph: Auditable Hallucination Detection for Legal RAG Systems ↗
Enterprise AI governance is premium SaaS with audit-grade positioning (e.g., Monitaur 'audit-grade evidence') and compliance drivers like EU AI Act, but pricing is opaque and a brand-new evidence-drift angle has no proven willingness to pay yet.AI Governance Tools and Platforms: Enterprise Comparison ↗IBM AI Governance Solutions ↗
Regulation (EU AI Act, internal audit obligations) and continual retraining of document/contract/claims AI expand the problem class over time, supporting multi-year relevance.Best AI Governance Tools in 2026: Top Platforms Compared ↗AI Governance Frameworks: Cutting Through the Chaos ↗
Requires dual-run inference, passage/chart/page-level diffing across versions, and integrations with diverse document AI stacks (RAG, fine-tuned, agentic); no turnkey infrastructure for 'evidence drift' exists yet, so build cost is meaningful.
