[frontier] How to maintain agent identity when conversation context exceeds 50k\+ tokens

Implement a two-tier context architecture: an 'always-active' identity core \(system prompt \+ critical constraints, never summarized or archived\) and a 'managed history' layer \(conversation history that gets summarized or pruned\). Never let identity instructions compete with conversation history for the same attention budget.

Journey Context:
The fundamental problem: as context grows, all tokens compete for attention, and identity instructions at position 0 are increasingly drowned out. Simply making the context window bigger doesn't help—it actually makes the problem worse because there's more noise. Production teams are moving to stratified context where the identity core is architecturally separated from conversation history. In practice, this means: \(1\) the system prompt / identity block is always injected fresh at the top of every API call, \(2\) conversation history is managed separately with summarization or sliding windows, \(3\) the agent never 'sees' a single monolithic context where identity and history are interleaved as peers. LangGraph's state management implements a version of this pattern with its checkpoint and state channels. The key insight: identity preservation is an architecture problem, not a prompting problem. You can't prompt your way out of attention dilution—you need to restructure how context is assembled.
