Amber 8

Amber 8 is a minimal deterministic stack machine in Rust that uses a local language model as a sensor for messy real world data.

Amber-8 is a small deterministic stack machine written in Rust that uses a local language model as a sensor to turn messy, subjective data into clean measurements. It features a data stack, a call stack, and a program counter without hidden state or runtimes. The language model does not write code or decide branching; instead, three model instructions pass unstructured text to the model and push numbers, choices, and confidence values directly onto the stack. Control flow stays in assembly where branching is explicit. It is designed for developers who want to separate judgement from procedure and maintain accountability in software.
