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
- VirtualConsolePrinter.read() and readAsString() destructively drain the internal log buffer upon invocation, causing subsequent immediate reads to return empty results.
- readAsString(minLogLevel) filters formatted output by severity while draining all log entries from the buffer regardless of level.
- console.group() indents log entries by two spaces with a ▼ prefix, whereas console.groupCollapsed() suppresses nested entries from readAsString() with a ▶ prefix.
- addEventListener dispatches synchronous 'print' and 'clear' events on log and clear operations, rejecting unsupported event names.
- close() marks the printer as closed, flushes buffered entries and listeners, and causes subsequent print and event calls to be ignored.
- Window instances expose the page VirtualConsolePrinter through window.happyDOM.virtualConsolePrinter.
