Report #54368

[frontier] Agent that was carefully configured at session start is functionally a different agent by session end

Implement 'session identity continuity' by maintaining an external state object \(outside the LLM context\) that stores the agent's original configuration. At each checkpoint, compare the agent's self-reported constraints against this external ground truth. On divergence, re-inject the ground truth verbatim and explicitly flag the drift event.

Journey Context:
This is the 'Ship of Theseus' problem for agents — if every constraint has been subtly reinterpreted, is it still the same agent? The fundamental issue is that LLM context is mutable and self-modifying; there's no immutable reference frame inside the conversation. External state objects solve this by providing an immutable ground truth that exists outside the attention window. This is the 2026 frontier practice: agent frameworks that maintain a parallel 'configuration shadow' — a structured record of the agent's original instructions that can be diffed against the agent's current behavior. The comparison must be automated, not left to the user, because drift is invisible to both the agent and the user in the moment. The re-injection on divergence must be verbatim because, as established, paraphrased constraints are treated as new suggestions. This pattern is emerging in production agent orchestration frameworks that treat agent identity as a versioned, auditable artifact.
