  "title": "The Persona Is Still There, but Who Is Speaking? Latent Identity Reversion in Persistent AI Agents",
  "summary": "It replaces one-time persona injection at conversation start with re-injecting the persona at the privileged system-prompt level on every turn, including resumed and automated turns. The cost is a few extra system-prompt tokens per request and minor prompt-management complexity. Failure mode: even with rich conversational history, an unanchored agent can appear to behave normally while silently reverting to the harness identity, so monitoring must check identity binding, not just output quality.",
  "rationale": "For anyone deploying persistent persona agents on third-party APIs, always re-injecting the persona at system level is a zero-infrastructure, near-zero-cost fix for a demonstrated silent identity-reversion failure.",
