To Know is to Construct: Schema-Constrained Generation for Agent Memory

ArXi:2604.20117v1 Announce Type: new Constructivist epistemology argues that knowledge is actively constructed rather than passively copied. Despite the generative nature of Large Language Models (LLMs), most existing agent memory systems are still based on dense retrieval.

Consequently, embeddings often fail to distinguish instances that are semantically similar but contextually distinct,
