Quality47

NoveltyiHow surprising the Jev use is versus an obvious typed-decision call. Generic mentions score low; a new primitive scores high.40
UsefuliHow reusable the technique is for another builder. Toys score low; a production-quality idea scores high.64
SubstanceiHow much concrete evidence supports the claim: code, numbers, demo, architecture. Hype scores low.34

Quality is Jev’s judgment of the idea. Likes, reposts and views do not affect it. Relevance is a separate gate.
