[frontier] Identity dilution when compressing context via RAG or summarization

Maintain a separate, non-compressible 'Identity Stack' containing the original system prompt, first user message, and key identity-defining exchanges. When compressing middle context via summarization or RAG, ensure the Identity Stack is concatenated at the END \(most recent position\) of the compressed context. Never summarize the Identity Stack.

Journey Context:
Standard context compression treats all tokens as equal information density, but identity is often established in early 'rapport chemistry' that is never repeated. When you compress turns 5-45, you lose the 'flavor' of turns 1-3 that defined the agent's voice and boundaries. Teams try putting rigid personas in system prompts, but this creates robotic, non-adaptive agents. The Identity Stack preserves the specific interactional 'chemistry' of early turns without token bloat, leveraging the recency bias by placing it at the end.
