  "title": "MemCalib: Benchmarking and Optimizing Memory Use in LLM Agents",
  "summary": "MemCalib-RL replaces generic post-training (GRPO, on-policy self-distillation) for memory-use behavior with an ordered bidirectional counterfactual credit-assignment algorithm that separates over-use and under-use signals and localizes credit via exact atom ablation. It costs a full RL training run on 8B to 35B-parameter models, which exceeds a single 24 GB GPU and requires counterfactual ablation infrastructure and training data; API-only users cannot apply it. After adoption it can fail if the calibrated behavior does not transfer to the deployed memory system or if the residual directional skew between over-use and under-use persists on out-of-distribution tasks.",
  "rationale": "The core contribution requires RL post-training of mid-scale models that is infeasible on the reader's constrained infrastructure, so the practical value lies in tracking the MemCalib benchmark as an evaluation tool rather than adopting the training method now.",
