Noulgate
A decoupled action guardrail powered by Jev: any system sends what it was about to do and gets back allow, deny or review, with Jev answering typed Choice, Score and Noul questions and a deterministic policy engine composing the verdict from them.

Highlights
- Any system sends what it was about to do and Noulgate returns allow, deny or review; your code owns the verdict.
- Jev answers typed Choice, Score and Noul questions; a deterministic policy engine composes the verdict.
- v1 scope: stable HTTP contract plus Python SDK, policy packs user_message.v1 and tool_call.v1, mock and jev providers.
- Design only for now: the plan lives in PLANO.md and runtime code is not in the repository yet.
- MIT licensed; created 2026-10-11 and pushed 2026-10-16; 0 stars.
Watch out
README and GitHub metadata reviewed 2026-10-17; the repository documents a design rather than runtime code, and the captured excerpt ends mid-response in the contract preview, so the evaluation logic and policy semantics are unavailable.

A planned decoupled action guardrail powered by Jev: any system sends what it was about to do, and Noulgate returns allow, deny or review, with the calling code owning the final verdict.
Jev answers typed questions — Choice, Score and Noul — and a deterministic policy engine composes the verdict from them; Jev does not generate text, run tools or grant permission, it only supplies judgments.
The v1 scope lists two: user_message.v1 and tool_call.v1, over a stable HTTP contract and Python SDK, with mock and jev providers and a local console for inspecting answers and verdicts.
No. The README says the design and implementation plan live in PLANO.md and that runtime code is not in the repository yet; the default provider will be mock, needing no credentials and no network.
A POST /v1/evaluate request carries a policy_id, an action and a payload — for example policy tool_call.v1 with a refund tool, order arguments and proposed_by model — and the response carries a verdict such as review.
The README is explicit that it is a judgment layer, not a full security stack: keep authentication, schema validation, IAM and specialized PII detectors in the calling system.
The captured excerpt cuts off mid-response in the contract preview, so the full policy semantics and evaluation logic are not visible; the repo is MIT licensed, has 0 stars, and was pushed 2026-10-16.

A safety guardrail for coding agents (Claude Code, Codex, Cursor, Antigravity, Grok) that intercepts shell commands, script executions and file writes before they run. Its neural tier can use Liquid AI d1-3B, CLM, TypeSafe Jev cloud or pure rules; a deterministic tier blocks destructive patterns in under 0.1 ms.

Bl4ckk01/agent-guardrailPythonA proof-of-concept HTTP service for constrained decisions with a local MLX model: send text or JSON plus typed choice, score, or noul questions and it returns probabilities over the answers you declared — no generated text, no parsed model JSON.

snellingio/system-onePythonAn independent open-source pipeline that gives Jev vision: it detects and tracks objects in images, video, and RGB-D camera feeds, then asks Jev a typed question about each relevant object and prints the chosen answer with its confidence.

eullm/eullmPythonA local workbench that pairs OpenCV vision with Laya or Jev decision models: images are segmented and measured, hard rules settle the numbers, and the model gives the verdict — with one-click installers and an "open-source JEV" training path served at /v1/systemone.

uu889/laya-opencvPythonA local, non-autoregressive security guardrail suite powered by Convai Innovations' Laya model, returning typed decision probabilities for security inspection. It positions itself against Jev on latency and against generative LLMs on hallucination risk.
