[frontier] Agent conflates user instructions with its own internal monologue, leading to authority confusion and instruction entanglement

Use Russian Doll Architecture: strict isolation of core identity prompts from conversational context with explicit XML/delimiter separation between user content, assistant reasoning, and identity metadata, preventing cross-contamination

Journey Context:
In extended sessions without strict message boundary enforcement, agents begin to treat their own previous outputs as user instructions or vice versa, leading to 'authority confusion' where the agent follows its own past suggestions as if they were user commands. Simple delimiters like 'Assistant:' fail because the model processes them as content. The Russian Doll Architecture uses nested, non-overlapping context segments where the core identity exists in a 'read-only' system segment that is never exposed to the conversational history, while the conversation exists in a separate 'read-write' segment. This is enforced by the inference engine's message API structure, not just prompt formatting. Alternatives like 'chain of thought' prompting actually worsen the problem by mixing reasoning and identity. This pattern requires specific API support \(like OpenAI's message roles or Anthropic's system prompts\) to enforce the isolation at the architecture level.
