Architecting Conversational Data Systems for Stateless LLM APIs: The Hydration Proxy Pattern

A new arXiv paper submitted on 1 Sep 2026 proposes the Hydration Proxy Pattern, an architecture that decouples session persistence from stateless LLM APIs to enable enterprise platforms to manage conversational state and semantic memory while maintaining platform sovereignty over data. The paper also introduces the Context Stabilization Mandate to resolve the tradeoff between sovereign state management and KV caching.

While statelessness enables horizontal scalability for AI providers, it forces client applications to manage the entire burden of conversational state and semantic memory. The work identifies the Hydration Proxy Pattern, an architecture that decouples session persistence from the reasoning engine. The framework ensures platform sovereignty over conversational data while enabling secure, multi-stage semantic grounding. We further propose the Context Stabilization Mandate to resolve the tradeoff between sovereign state management and KV caching. References & Citations Loading...
