Sovereign Execution Brokers: Enforcing Certificate-Bound Authority in Agentic Control Planes

Giving AI agents the ability to modify cloud infrastructure, databases, or deployment pipelines introduces a dangerous gap: a model that reasons incorrectly or gets manipulated could execute irreversible, high-impact actions. Existing security frameworks authorize identities, but they do not enforce that a specific certified action plan is what actually gets executed. The Sovereign Execution Broker sits between an agent's intentions and real-world infrastructure mutations, verifying that every action matches a certified contract before it proceeds. This architecture is particularly relevant for DevOps automation, cloud cost management agents, and any agentic system operating in environments where unauthorized mutations carry serious consequences.
