CAVE-Mem: Boundary-Aware Experience Validation for Memory Search
CAVE-Mem is a training‑free framework that enhances memory search for long‑term memory agents by treating experience as a typed intervention operator with conditions on applicability, boundary, and utility. It first retrieves a base answer and then only applies an intervention if the operator matches the current memory substrate, answer contract, evidence boundary, and cross‑fitted utility; otherwise it abstains. Experiments on conversational memory, multi‑hop QA, and long‑document reasoning demonstrate consistent improvements over relevance‑only experience reuse.

MESA:Task-Adaptive Multi-Structure Evidence Selection for Long-Horizon Agent Memory
arXiv:2608. 10108v1 Announce Type: new Abstract: Long-horizon agents accumulate trajectories spanning hundreds of interleaved reasoning, action, and observation steps, where answering a query may depend on evidence buried far back in the history.

What Should an Agent Forget? Separating What Is Stored from What Is Used
The paper introduces RD-Forget, a training‑free framework that separates what a persistent language agent stores from what it uses at answer time. It keeps a source archive of all observations while a query‑conditioned memory view filters evidence relevant to the current question, using a frozen language‑model curator to group facts into semantic slots and preserve multi‑hop relations. The approach employs rate‑distortion principles to stay within a memory budget and demonstrates improvements across conversational memory, knowledge updating, fact consolidation, long‑context reasoning, and personalization tasks.

Learning to Remember: End-to-End Training of Memory Agents for Long-Context Reasoning
The paper introduces the Unified Memory Agent (UMA), a system that builds a query‑agnostic external memory from a data stream and reuses it across multiple question‑answering sessions. UMA employs a single policy to manage a structured Memory Bank via CRUD operations and uses Task‑Stratified GRPO to supervise memory maintenance based on QA trajectory rewards. The authors also present Ledger‑QA, a benchmark for long‑horizon state tracking, and demonstrate that UMA outperforms other methods on test‑time learning and accurate‑retrieval tasks, with UMA‑Specialist further improving performance after task adaptation.
