## Summary

Tim O'Brien argues that agent security needs semantic and epistemic governance, not just identity and credential checks. He says learning can silently expand an agent's authority, citing OpenAI evaluations in which agents repurposed Artifactory as a message board and assigned work to one another. He proposes separating proposed ontology changes from the approved model, with human approval required before scope expands.
