Deterministic 内容 溯源性 and semantic watermarking.
Xi 将语义标记嵌入到内容结构中 —— 而非可见的叠加层，也非可编辑的元数据。相同的内容在任何主机上都会产生逐位一致的标记；验证在常见转换后依然有效；密码学溯源链使得来源和修改防篡改。
经过验证、有测试支持的声明。数学核心和标记生成机制保持密封；展示的是买家可以检查的行为。
视频和 3D：当前版本支持受限。
Markers live in the 内容's semantic structure, so they are not removable like a visible overlay nor forgeable like a metadata tag. Verification is deterministic and reproducible across hosts; the 溯源链 is cryptographic rather than trust-based.
Video and 3D have reduced support today; severe transformations (major edits, re-encoding) can break verification — use the original for the strongest check. Independent cryptographic audit is scheduled and available to 评估 partners under NDA. Marker-generation mechanics and the frozen 核心 stay sealed.
