DreamBench-SWE: A Multi-Session Memory-Hygiene Benchmark for Software Agents

Read the original on arXiv AI →

DreamBench‑SWE is a multi‑session benchmark designed to evaluate software agents’ memory hygiene, where later tasks rely on evidence from earlier sessions and are scored by executable hidden oracles. The study reports results from an original scaled v2 fold and a preregistered v2.1 successor audit, detailing performance across various memory configurations and conditions. The findings confirm that DreamBench‑SWE can discriminate between different memory setups, but do not establish superiority, equivalence, or broad generality of any external‑system mechanism.

LSREP: A Longitudinal State-Replay Protocol for Evaluating Conversational Memory, with ICE v2 as an Audited Local-First Architecture

The paper introduces LSREP, a Longitudinal State‑Replay Evaluation Protocol designed to assess how conversational memory evolves over time, incorporating ordered replay, lifecycle schedules, repeated probes, evolving reference answers, and mechanism‑fidelity checks. It applies LSREP to ICE v2, a local‑first memory middleware, and reports that on three ordinary‑density datasets ICE v2 achieves near‑zero mean quality difference from vector‑RAG while using fewer fragments but slightly more prompt tokens, yet fails catastrophically on a dense dataset. In a public diagnostic, ICE v2 underperforms pure vector‑RAG on LongMemEval, revealing significant multi‑session and temporal failures and a quality‑cost trade‑off rather than superior efficiency.
