What it is
Dub is an open-source link attribution platform for short links, conversion tracking, and affiliate programs. It is used by marketing teams at companies like Twilio, Buffer, Framer, Perplexity, and Vercel.
How it uses Jev
In malicious-link-check.ts, Jev is called before a short link is created. The URL is gated by a typed verdict rather than a blocklist, but the README does not specify the state, questions, or how the result is used in code.
Technique worth stealing
Gate short-link creation with a typed verdict instead of a static blocklist.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
