PriorityFresh is a semantic, actionability-first caching policy designed for offline emergency warning systems. Within the AWARE system's simulation environment, PriorityFresh optimizes which alerts to retain and surface under constrained connectivity. Experiments indicate improved actionability-first performance without harming efficiency. A separate Priority Forecasting model is used only to synthesize realistic alert sequences for controlled experiments and does not influence caching or push decisions.
