 T-102 已证明 canonical 链接可进入目标商品。T-103 在 PKG110 / Android 16 / 拼多多 8.17.0、goods_id `937122477375` 上确认：规格面板由详情页精确唯一的“快要抢光”打开；T-110 已把该证据/版本绑定入口批准为受控导航。面板刚打开时目标颜色“黑色CHA(纯棉)”和尺码“M(建议100-115)”自动选中。

 2026-08-04 T-103 入口父链收紧完成：提交 44586fe，合入主分支 ce9d6ca。入口只允许精确唯一“快要抢光”子节点及五层已取证可点击 PDD 祖先链，实际点击仍取子节点中心；“免拼购买”独立容器为硬拒绝。独立审计复算证据 hash、验证 focused 32 / full 112 tests 和完整 init 均 PASS。最终真机运行曾安全失败且未发布输出目录；随后只读诊断发现系统通知栏覆盖，app_current 虽仍报告 PDD，但节点树 64 个节点全部属于 SystemUI。下一次必须由人先完全收起通知栏并停在 PDD 首页再运行；T-103 保持 DOING，不把这次失败或入口截图确认误记为完整验收。

+- 人工复跑先因 NotificationShade 覆盖和 USB/Wi-Fi 双 ADB 通道同时在线而安全失败；收敛为仅保留 Wi-Fi ADB、拼多多前台为 HomeActivity 后，仍以 generic failure 安全停止且未发布证据目录。
+- 主线提交 `870e5f8` 为真机 CLI 增加只来自固定白名单的 failure stage；异常正文、serial、路径与 XML 均不回显，hostile getter、`str` 子类和 setter 全部失败闭合为 `unknown`，原异常类型、finally 安全调和、单击不重试与失败不发布语义保持不变。
+- 独立终审 PASS；T-103 33 tests PASS，client 全量 233 tests PASS，仓库根 `init.ps1` PASS。
+- 尚待项目所有者使用新 CLI 再次真机复跑；T-103 保持 done=false / Doing，并继续保留 needs_device 与 needs_human_review 门禁。
