DeerFlow 防循环源码：调用归一化、指纹和有界状态

// 仅模拟整数行范围，不是上游 Python 运行时。
function readBucket(path, start = 1, end = start) {
  const [lo, hi] = [start, end].sort((a, b) => a - b);
  return `${path}:${Math.floor((Math.max(lo, 1) - 1) / 200)}-${Math.floor((Math.max(hi, 1) - 1) / 200)}`;
}
console.log([readBucket("a", 1, 199), readBucket("a", 200, 1), readBucket("a", 201)]);
