What it is
DiffJury is a web app that fetches a public GitHub pull request and uses Jev to judge merge risk, review depth, and whether design or security review is needed. It is for teams that want to triage PRs before assigning a human reviewer.
How it uses Jev
On the server, POST /api/review sends the PR title, body, diff, and optional CI log and linked issue to TypeSafeClient.systemOne. Jev returns answers for nine typed questions (risk, review_depth, needs_design, needs_security, merge_blocker, missing_tests, docs_debt, blast_radius, verdict). The UI shows risk bars, noul probabilities, and a verdict.

Technique worth stealing
Use one Jev systemOne call with multiple typed questions to get calibrated probabilities for PR triage.
Try it
npm install, set TYPESAFE_API_KEY in .env.local, npm run dev, open http://localhost:3000.
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.
