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。

契约
- StreamOutput does not close its underlying stream resource when destroyed, leaving the file descriptor open unless explicitly closed with fclose by the caller
- ConsoleOutput caches its stdout and stderr streams in private static variables, sharing the identical stream resource across separate ConsoleOutput instances
- OutputFormatter retains unclosed tag styles on OutputFormatterStyleStack across separate format and write calls, propagating styles into subsequent messages until explicitly closed with </>
- QuestionHelper on encountering EOF from a StreamableInputInterface permanently sets isInteractive to false on the input instance, silently disabling interactive prompts for all subsequent questions
- ProgressBar instantiated with ConsoleOutputInterface writes progress output to getErrorOutput() (STDERR) instead of STDOUT, and ProgressBar::finish() omits a trailing newline
- BufferedOutput::fetch() destructively drains the internal buffer rather than caching it, returning an empty string on subsequent calls
- Cursor::hide() and Cursor::show() emit the ANSI sequences \x1b[?25l and \x1b[?25h\x1b[?0c without resetting cursor visibility upon command completion or object destruction
