// 输入修剪语义(首尾空白/NUL 裁剪)与 DuckInfo 扫描位置;本探针为独立小程序,未复制算法代码。
// 许可:上述为 duck.ac 公开提交;本件按署名账号+原提交 URL 引用思想。
// ===== 思路(试验性诊断探针 v2:volatile 触页防止死代码消除)=====
// 目的:读出 1006 每个隐藏测试点的形状统计量:不同字符数 dc 与跑段数 nr。做法:只扫描输入
// (不跑算法),把 dc 与 nr 编码为触页数:pages = dc*1024 + nr/64,提交页“内存”列反读
// (mem_kb ≈ pages*4 + 基线)。输出为空 ⇒ WA 诊断探针,不参与达标口径。
