What it does

A TrainLCD contribution that adds Jev-based reranking to its Functions workers.

How you can use it

A developer can adapt this project's testing script. It uses an outside AI service called TypeSafe. The service checks if proposed train stations actually match what a user asked for. Your developer can run these tests safely before updating the real app. This helps them see if the AI makes good choices.

To borrow this method, your developer needs an access key that connects the app to TypeSafe. The working app double-checks the choices only once for every chat message. This rule stops users from waiting too long for a reply.
