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
- DriverManager::getConnection() throws DriverRequired when passed a raw 'url' parameter without driver or DsnParser
- Connection::executeQuery() throws MissingNamedParameter if named parameter keys include a leading colon ':'
- Connection query and execution methods throw TypeError if passed integer type constants instead of ParameterType or ArrayParameterType enums
- ArrayParameterType::INTEGER expands array values in IN (?) clauses and safely converts empty arrays [] to IN (NULL)
- Connection::fetchOne() returns null when a column is SQL NULL but returns false when no matching row exists
- Connection::fetchAssociative() returns false on missing rows while fetchAllAssociative() and fetchFirstColumn() return empty arrays []
- Connection::insert, update, and delete return the integer count of affected rows
