Let the agent's persona evolve freely, keep execution faceless and audited, and bridge the two through a governed contract
arXiv 2608.27427 (2026-08-27) names a pattern for agents in regulated settings: put persona and execution in separate trust domains joined by a contract bridge with approval matrices and DLP, so instructions and presentation can drift while the execution record stays traceable. Status summaries may cross the bridge, sensitive data may not, and 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, which is the concrete failure the pattern exists to catch.
