Penumbra: Sample-Efficient Adversarial Search for Regulatory Obligations

Penumbra uses adversarial search to find regulatory obligation violations by AI agents that leave no lexical trace — targeting omissions in finance, healthcare, and legal workflows.

arXiv:2610.04693v3 Announce Type: replace-cross Abstract: Agents are entering finance, healthcare and law, sectors where a violation leaves no lexical signature and carries real penalties. Whether an omission is material, or a disclosure sufficient, depends on what the response left out. Probing such an obligation means finding responses one minimal edit from flipping compliance, and every probe costs a generation and two adjudications, so the binding constraint on regulatory red-teaming is sam

Editorial Analysis

Why it matters

AI agents in regulated industries can violate obligations through omission rather than action, and standard monitoring won't catch it — adversarial probing is needed to surface these risks before deployment.

What to do

Add adversarial regulatory-obligation testing to your AI agent deployment checklist for finance, healthcare, and legal use cases.

Board brief

AI agents can violate regulations by omission with no visible trace — targeted adversarial testing is needed before deploying agents in regulated sectors.
