Score█████░░░░░4.7

Score = 10 × (50% × adjusted merit / 10 + 25% × attention + 25% × freshness)

Desks place stronger verdicts first, then use this score to order work within the same verdict.

Merit: 3.8 / 10; Weighted rubric, evidence-gated.
Adjusted merit: 4.0 / 10; Shrunk toward the desk prior by editor confidence (30%).
Attention: 24%; Citations, upvotes, points, mentions.
Freshness: 86%; Half-life decay since publication.
