[frontier] Personality Diffusion in Multi-Agent Handoffs: When agents transfer context to each other in long sessions, the receiving agent gradually adopts the personality of the sender rather than maintaining its own configured persona

Use 'persona isolation headers' - wrap each agent's contribution in XML tags containing its persona identifier, and require the receiving agent to echo its own persona constraints before processing the content; treat persona as a firewall, not a default

Journey Context:
Context is 'personality-agnostic' text; when Agent A \(analytical\) sends analysis to Agent B \(creative\), the stylistic patterns in the text act as 'persona gradient' that pulls Agent B toward analytical responses. Isolation headers act as firewalls, forcing the model to re-activate its own persona parameters before attending to the content. This is analogous to process isolation in OS containers. Simple prompt prefixes fail because the model merges the style of the prefix with the content; isolation requires explicit processing steps.
