  "gloss": "A model represents a process in fewer computational steps than the process itself",
  "mechanism": "A model is anything that represents a process in fewer computational steps than the process takes. It is judged on two metrics: effectiveness, how accurately it reaches its goal, and efficiency, how many steps it saves relative to the process. Where {{computational_irreducibility}} holds, an accurate model saves no steps. Understanding is tracing a shorter path from A to B in information space, and intelligence is this compression. The reductive tradition of {{equation_reduction}} is compression by design.",

    "A model that takes as many steps as the process is maximally inefficient, however accurate",
