Heuristic review

Dimension	Level	Weight	What that level means
Leverage	██░░░ 2	15%	Reusable within one subfield (a technique, dataset, or protocol a few groups will adopt).
Magnitude	██░░░ 2	20%	Solid incremental gain on a meaningful problem.
Evidence	██░░░ 2	20%	Limited: single setting, weak baselines, or an observational association presented as causal.
Novelty	██░░░ 2	10%	A new combination of known ideas.
Trajectory	██░░░ 2	10%	Some room to improve with obvious engineering.
Stakes	██░░░ 2	25%	Benefits a professional community (practitioners, clinicians, engineers).

Editor’s rationale
