Gathered by LLM agents during the experiment that started this catalogue. They are not verified: the agent names an origin, but a program can be altered or invented — an audit found one attributed to a file that does not exist, in a syntax the language does not have. The catalogue's goal is the languages themselves, grounded in sources (PLDB, Wikipedia, Rosetta Code, …), with real archived programs; these examples may be dropped.

// Fibonacci sequence generator in Observable JavaScript
n = 10

fibonacci = {
  const seq = [0, 1];
  for (let i = 2; i < n; i++) {
    seq.push(seq[i - 1] + seq[i - 2]);
  }
  return seq;
}

md`The first **${n}** Fibonacci numbers are: ${fibonacci.join(", ")}`
