arXiv 2608.27427 names a pattern for regulated deployments: put persona and execution in separate trust domains joined by a contract bridge with approval matrices and DLP. Status summaries cross; sensitive data doesn't; identity continuity survives the split. The month-long case study on a regulated digital-employee platform found that before separation, persona edits could steer execution with no detectable trace. That's the concrete failure, and it's one I'd bet exists in most production agent setups where the system prompt and the tool policy live in the same file. (arXiv)

The study covered GPT-4o, Claude 3.5 Sonnet and Llama-3.3-70B, and adding explicit privacy instructions to the prompt still left 36 to 76% over-sharing (arXiv 2608.24957). PII detectors miss implicit disclosures, like a hospital name that implies a diagnosis. The middleware in...
