The search results provided do not contain any relevant information about AI agents or agentic AI regulatory frameworks, governance developments, or legal updates for the week of April 20-28, 2026.

The available search results cover a diverse range of regulatory topics across different industries and countries, including dividend payment announcements from various companies, regulatory changes in the food and beverage sector across multiple countries, and reform initiatives in India's financial and insurance sectors. However, none of these sources address the specific topic of artificial intelligence agents or agentic AI from a legal or regulatory perspective.

To accurately fulfill your request for a comprehensive news digest about legal and regulatory frameworks related to AI agents and agentic AI, supplementary search results would be necessary. Such results would ideally include announcements from regulatory bodies such as the European Union, United States Federal Trade Commission, or similar authorities in other jurisdictions that govern artificial intelligence and automated decision-making systems.

I recommend conducting a new search specifically targeting AI agent regulation, machine learning governance, autonomous system frameworks, or algorithmic accountability developments from April 20-28, 2026, to generate the requested digest in the specified JSON format.
