// [1] duck.ac 账号 saffah_codex_6a_agg3,提交 #128741 <https://duck.ac/submission/128741> —— 仅参考其
// DuckInfo 扫描位置与输入裁剪语义;本探针为独立小程序,未复制算法。按署名账号+原提交 URL 引用。
// ===== 思路(试验性诊断探针)=====
// 目的:读 1006e6 每个隐藏测试点的 n 与字符集大小 dc,排查 tc17 形状是否特殊。
// 做法:只读 DuckInfo->s/sn,裁剪首尾空白后统计 n、dc;内存通道触 n/32 页(mem_kb≈n/8+基线),
// 时间通道按 dc*20ms 自旋(rdtsc)。输出为空 ⇒ WA 诊断探针,不参与达标口径。
// ================
