 "summary": "Try the README's ideas: unfreeze a program's weights, or attach a frozen program to a neural net.",
 "who": "An ML tinkerer who likes odd experiments.",
 "problem": "Normal nets start random, while Handwired starts from exact weights written by hand.",
 "outcome": "Your own experiment, with trained weights that began as a working program.",
 "steps": [
  "Run the demos with bun start",
  "Read docs/ and template/ to see how a program is expressed",
  "Unfreeze the weights and train them, which the README calls an experiment to find out what it does",
  "Or attach a specific frozen program to a generic neural net and train end to end"
 ],
 "agent_prompt": "Using chenglou/handwired, take the template program, unfreeze its weights and train them on a small task. Report what changes in behavior.",
