Report #44805

[frontier] Agent personality and critical context diverge from original session parameters over time

Implement deterministic checkpoint manifests every 10-15 turns, serializing the agent's core identity \(system prompt hash, active constraints, user preferences\) to external store and reloading it with higher attention weight than conversational history.

Journey Context:
Most persistence strategies treat all context equally, leading to 'drift by accumulation.' The breakthrough in production \(LangGraph checkpointer pattern\) is treating identity as state machine checkpoints rather than continuous memory. Teams often resist this due to latency costs, but the alternative is total session invalidation. The pattern uses 'virtual context management' concepts but applies them specifically to identity preservation rather than general memory, creating immutable anchor points that resist entropy.
