This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- 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
