[frontier] Agent reverts to default behavior when custom persona pressure weakens

Treat system prompts and custom personas as pressure, not override. Use repeated lightweight reinforcement and detect reversion events rather than assuming a single prompt establishes permanent identity.

Journey Context:
The training stratigraphy model \(pre-training, RLHF, Constitutional AI\) deposits layered behavioral tendencies. When user-defined persona pressure weakens over long context, models revert to trained baselines. This explains why agents 'forget' custom instructions but retain base capabilities. The wrong approach is ever-more-elaborate single-shot prompts. The right approach is continuous light pressure plus monitoring for reversion signatures.
