Heuristic review

DimensionLevelWeightWhat that level means
Leverage██░░░ 215%Reusable within one subfield (a technique, dataset, or protocol a few groups will adopt).
Magnitude██░░░ 220%Solid incremental gain on a meaningful problem.
Evidence██░░░ 220%Limited: single setting, weak baselines, or an observational association presented as causal.
Novelty██░░░ 210%A new combination of known ideas.
Trajectory██░░░ 210%Some room to improve with obvious engineering.
Stakes██░░░ 225%Benefits a professional community (practitioners, clinicians, engineers).

Editor’s rationale

Heuristic triage from title and abstract text only, not a reading of the paper. No strong cues found.
