20 种载体格式 × 8 类真实变换 = 160 个实测单元：写入 NF 标识 → 变换 → 用同一检查器复检。每格都有哈希与证据。

PASS=标签与签名都存活；LOST=检不到/验不过；N/A=该格式不适用。合成夹具，真实软件可能不同。
同样的变换，换标注策略再测一遍：只写元数据 36/77 存活；加可见标记 75/77；三层 75/77（10 格式 × 8 变换 × 3 策略 = 240 单元）。
| 策略 | 存活/可执行 | 存活率 | 说明 |
|---|---|---|---|
| metadata | 36/77 | 47% | NF 七字段 + SM3/SM2 |
| visible | 75/77 | 97% | 图片角标/文档页脚/音频提示音/视频角标 |
| layered | 75/77 | 97% | 元数据 + 可见 + sidecar（推荐） |
失败集中在 PDF 栅格化与 WAV 重采样；可见标记不是鲁棒水印，对抗性裁剪仍可能破坏。承诺边界是「受控闸门内存活 + 失效可定位」，不是「任何情况下保证」。
| 能力 | 结果 | 说明 |
|---|---|---|
| 二维码绑定（防移植） | 对抗 7/10 | ID + 内容哈希 + SM2 + dHash；裁剪/旋转/覆盖失败 |
| 不可见水印（DCT-QIM） | 对抗 5/10 | JPEG/缩放/模糊/噪声/调色通过；截图/裁剪/旋转失败 |
| 批量 / 监听 / 本地 API | 已实现 | batch、watch（可隔离失败）、serve（127.0.0.1） |
这些是实测结果，不是「绝对保证」；报告里写明了失败场景与边界。
