Apache-2.0 ModernBERT fine-tune that answers noul, choice, score and multi-label questions with a probability for every option. It serves Jev's POST /v1/systemone locally so TypeSafe's Python SDK runs unchanged, reporting 0.026 expected calibration error on its test split.

Feed Lens

Chrome extension that adds user-defined topic and expression labels to Weibo, Threads and X posts. It uses Jev Noul judgments against per-platform dictionaries, up to 60 labels per platform, and sends post text and label rules directly to TypeSafe under your own API key.

openclaw-jev-leakguard

OpenClaw plugin that checks every outgoing agent message against its destination channel tier, running local key-format and term rules and then five Jev Noul questions in one call through OpenClaw's decisionModel, which can point at hosted Jev or a local Kev.

jev-table-import-mapper

A dependency-free JavaScript library that maps uploaded CSV columns onto your destination schema: a strict normalized-name pass first, then one Jev boolean per remaining source-destination pair plus a guard question per column, leaving uncertain fields visible instead of guessed.

Jev Slop Guard

A bring-your-own-key Chrome extension that asks Jev one slop/not_slop Choice per X or LinkedIn post as it scrolls into view, then blurs and stamps anything at or above a configurable threshold. Scrolling never blocks, and each post is scored once from a local cache.

Jev AI Detector

A lightweight Chrome extension that scores selected webpage text for how strongly it resembles AI-generated writing, using Jev inline in the browser after a right-click or Cmd/Ctrl+Shift+Y. It aims to give readers an uncertainty-aware signal without interrupting reading.

LinkScout

A browser extension plus Cloudflare Worker that scores search results before you click: Jev answers six questions per page (relevance, depth, SEO filler, sales page, page type, key passage) and code combines them into a 0-100 badge that re-ranks Google, Bing, DuckDuckGo and 104.com.tw.

DeepSeek Harness Jev Plugin

203

Native DeepSeek Harness (DSH) plugin that uses Jev or Luna Decisions as a System One judgment layer across 12 separately configurable features: skill selection, file ranking, drift reminders, completion checks, goal supervision, corrections, log admission and workspace approvals. All features ship disabled by default.

JevCI

CLI quality gate that asks four typed questions about each change - three Score lenses for commit quality, doc alignment and breaking-API risk, plus a Noul secret audit - and fails a diff, commit message or doc set below the resulting 0-100 score. Runs from a terminal, a git pre-commit hook or a GitHub Action.

Rot Guard

MIT-licensed Chrome extension that asks Jev whether the page, video or post you are on serves your written goals -- a category Choice, a goals Noul and a 0-4 waste-of-time Score -- then blocks or blurs in code, tightening thresholds at 2, 10 and 20 minutes of engaged time.

Jev Resume Screening

Reproducible recruiting cookbook that screens one resume against a job description in a single parallel Jev request of five Noul evidence gates, four Score dimensions and one background-routing Choice, with criteria iterated v1 to v3 against positive, negative and trap resumes.

JevPilot Reflex

Three.js autonomous-driving simulator that splits work between a System 2 slow planner and a Jev-style System 1 reflex loop at 60 Hz, with a safety brake that overrides the planner and applies full braking when time-to-collision drops below threshold.

decision-gate

Pre-1.0 npm library that every Jev request in a loop goes through: it waits for room under 80% of the account's requests-per-minute and tokens-per-second limits, pauses all local callers on 429 for the server's Retry-After, and refuses requests above a per-key daily spend ceiling of USD 0.20 by default.

SAP S/4HANA Procurement Fraud

Proof of concept that flags suspicious purchase orders in SAP S/4HANA: ABAP computes risk indicators, a Fiori Elements app sends seven typed questions to Jev via OpenRouter, and ABAP applies thresholds to rate each order. Runs in shadow mode only.

Pacman AI Race

Browser Pac-Man race where a deterministic three-junction simulation filters fatal routes, then Jev makes one typed Choice among the surviving route IDs while the server rejects any answer outside the supplied set. Self-hosted Laya runs the same contract for comparison.

jev-verify

Node.js CLI that checks whether published Jev outputs were actually produced by Jev: it recomputes the Yurin confidence identity and the expected-score formula over a repository's artifacts and flags fixtures that violate them. No API calls, no dependencies, Node 18+.

Tab Sorter

Chrome MV3 extension that groups every tab in a window into named, colored groups from one parallel Jev call - one Choice question per tab against user-edited criteria, with a fixed fallback bucket, manual groups untouched, and the original tab order restored on ungroup.

pi-gear-router

Pi extension that has Jev score each user request on a continuous 0-2 scale and cuts that range into five bands choosing one of three model gears (light, standard, heavy) plus a thinking level. A plain "continue" can inherit the current gear without a new Jev call.
