Report #35697

[frontier] Agent drifts from original debugging persona to generic helpful assistant; resetting loses all session context

Implement Session Bifurcation: Periodically snapshot agent state \(system prompt \+ key context fragments\) to immutable checkpoint store \(e.g., Redis with TTL\). When drift detected \(via lexical analysis or shadow prompting\), spawn new agent instance from last known-good checkpoint, replay summarized history with identity reinforcement \( tags\), and continue session seamlessly.

Journey Context:
Traditional 'reset' loses conversation history. Simple 'remind' messages are ignored. Bifurcation treats the agent session like a git repository—branching from known-good state. The replay mechanism must be intelligent \(summarization with identity preservation\), not raw message replay. This requires infrastructure to manage agent lifecycle \(containerized instances or stateless functions with hydrated context\). Tradeoff: adds ~500ms-2s latency during bifurcation event and requires checkpoint storage. Alternative 'continue anyway' leads to progressive capability degradation.
