本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

HOW- 目标
- Parse C99 source declarations into a FileAST hierarchy, manage typedef scoping with isolated state per invocation, and track source coordinates with CParser.parse in pycparser 2.22.

契约
- CParser().parse parses C99 source declarations into a typed FileAST hierarchy preserving node coordinates and declaration structures.
- CParser().parse isolates typedef symbol table scope across successive parse calls on the same instance, raising ParseError when undeclared types are referenced.
- CParser().parse recognizes #line preprocessor directives and overrides source file and line coordinate attributes accordingly.
- CParser().parse requires preprocessed C source input, raising ParseError on unsupported preprocessor directives and raw comments.
- CParser().parse parses empty input strings into a FileAST instance with an empty declaration list.
