+# analyze_enum_trace.py - 分析客户端「枚举读取」打点：确认读 enum 时字节游标是否推进
+#
+# 数据来源：镜像站 module_24635.js 的 Kt.t7h 补丁（枚举读器）。它记录
+#   {enum: 枚举 kClass 名, pos0/pos1: 读前/读后的字节游标, bit: nullmap 位游标}
+# 节流 POST 到 serve.js 的 /__dump__/enum_trace.json。
+#
+# 判读：
+#   pos1 - pos0 == 0 → 该枚举不占字节（与源码 EnumCodecInfo/Kt 空实现一致）；
+#   pos1 - pos0 != 0 → 客户端确实为这个枚举读了字节，说明宽度不是常量。
+#
+# 用法: python tools/analyze_enum_trace.py [--names names]
