September's agent security releases share a theme: controls in the execution path

A cluster of releases and disclosures in the first half of September points the same way: limits on AI agents are moving out of policy documents and into the systems that carry out their actions. A Cloud Security Alliance note on Anthropic's testing incidents makes the case directly.
