 GhostScope 是一个 **面向源码语义的用户态追踪器**。有 DWARF 调试信息时，它可以在不由调试器控制目标暂停的前提下，按函数、源码行或指令粒度设点，打印真正重要的信息，并输出源码感知的调用栈。
 
-支持范围以及可信输出所依赖的不变量，统一定义在[设计保证与可信性模型](docs/zh/design-contract.md)中。
+C 的端到端覆盖最完整。对于 Rust 目标，GhostScope 为常用值提供定向支持，并会对应用、标准库和 inline backtrace 栈帧中的符号进行 demangle。准确的支持边界见[源语言支持现状](docs/zh/scripting.md#源语言支持现状)和[使用限制](docs/zh/limitations.md#1-语言支持)。

 GhostScope is a **source-aware userspace tracer** for live Linux processes. With DWARF debug info, it lets you attach at function, source-line, or instruction granularity, print the values that matter, and emit source-aware call stacks without debugger-controlled suspension of the target.
 
-The supported operating envelope and the invariants behind trustworthy output are defined in [Design Guarantees and Trust Model](docs/design-contract.md).
+C has the strongest end-to-end coverage. For Rust targets, GhostScope provides targeted support for common values and demangles application, standard-library, and inline backtrace frames. See [Source Language Support](docs/scripting.md#source-language-support) and [Limitations](docs/limitations.md#1-language-support) for the exact boundaries.
