NanoJev: a 0.6B open-source Jev replica

NanoJev is a 0.6B open-source replica of Jev that takes states and questions and returns complete probability distributions with zero output-token decoding. Ships with model weights, dataset and an end-to-end training pipeline, plus a side-by-side demo running Jev, NanoJev and untuned Qwen through Snake and a 50x50 maze.

NanoJev eliminates the target with one shot while Jev and Untuned Qwen fail, shown side by side on the same game clock
