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
- Running a failing command with --silent (VERBOSITY_SILENT) exits with code 1 but completely suppresses exception rendering, while --quiet (VERBOSITY_QUIET) renders the exception message to error output
- Under --silent verbosity, isSilent() is true, isQuiet() is false, and input interactive mode is forced to false
- InputOption::VALUE_NEGATABLE defaults to null (tri-state unset) when omitted rather than false, sets true on --flag and false on --no-flag, and accepts boolean defaults in 8.1 while throwing LogicException on non-boolean defaults
- ArgvInput greedily consumes the next token as the value for VALUE_OPTIONAL options without an equals sign, leaving subsequent required positional arguments unfulfilled
- ArrayInput requires '--' prefix for option keys; passing an unprefixed key sets a matching InputArgument instead and leaves the option at its default value
- In ArrayInput, the '--' delimiter key immediately terminates parsing of all subsequent arguments and options
- QuestionHelper::ask() in non-interactive mode executes question validators but silently skips normalizers on the default answer
- ChoiceQuestion with an associative choice map returns the matching key string rather than the choice label, even when selected by label
