traffic-guard

hemanth

1177

Security & Guardrails E2 · source reviewed

A Node/Python HTTP request gate combining local allowlists and verification with optional TypeSafe questions about bot behavior, attacks, spoofing, traffic category and risk.

JEV · Decision point

traffic-guard progressively evaluates requests against TypeSafe System One using Noul (`is_bot`, `is_attack`, `is_spoofed`), Choice (`traffic_type`), and Score (`risk_level`).

Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.

CLI & Pipelines E1 · source linked

Jev from Typesafe.ai is a "System One" AI model that returns **typed, calibrated judgments** instead of generating text. You define what to classify (a Choice), score (a Score), or verify (a Noul), and Jev returns a structured answer with a probability distribution — fast, cheap, and directly consumable by code.

JEV · Decision point

Jev returns a structured decision for the local program; consult the source for the exact decision policy.

Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.

High-Frequency & Simulation E1 · source linked

This is a **simulation**. It is not connected to, and cannot control, any real traffic signal — Hong Kong's Transport Department publishes no write API for that, only a read-only feed of sensor data. Everything downstream of that feed (the phase timing, the amber/all-red clearance, the safety limits) runs entirely in this process's own memory.
