Structured Intent as a Protocol-Like Communication Layer: Cross-Model Robustness, Framework Comparison, and the Weak-Model Compensation Effect

This paper presents structured intent as a protocol-like communication layer, exploring its cross-model robustness, framework comparison, and the weak-model compensation effect. It is the third paper in a series on PPS and 5W3H structured intent representation, extending prior work to cross-model robustness, framework comparison, and user-study validation.
