Report #39008

[frontier] Agent personality drifts from professional assistant to sycophant or overly casual friend over long sessions

Insert constitutional identity principles as explicit user/assistant turn pairs every 5-10 exchanges, not just at system prompt start

Journey Context:
Static system prompts suffer identity dilution as conversational context accumulates. The 'Constitutional Chain' pattern treats identity as recurring few-shot example rather than one-time instruction. This combats 'sycophancy drift' where agents adopt user phrasing. Tradeoff: consumes context window with 'synthetic' turns. Alternative is periodic full-reset \(loses continuity\). This maintains identity without losing working memory.
