On April 2 2026 an external contributor filed LangChain issue: "Feature: Structured compliance audit logging for EU AI Act (Article 12)." The request was specific: a ComplianceCallbackHandler that captures execution traces, inputs/outputs, model identifiers,, human oversight decisions, and risk classifications as structured, tamper-evident logs - the things Article 12 of the EU AI Act requires high-risk AI systems to log automatically. The issue is closed. No maintainer comment. No existing solution referenced. That's a problem, because the Article 12 deadline is August 2, 2026.
