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
- DateTime.fromISO and DateTime.utc parse valid ISO strings and maintain date components
- DateTime.fromISO marks unparsable strings as invalid with unparsable reason
- DateTime arithmetic with plus and minus produces new instances while keeping original instances immutable
- DateTime startOf and endOf correctly adjust time boundaries
- DateTime toFormat and toISODate produce properly formatted date strings
- DateTime diff calculates accurate day and hour differences as Duration objects
- Duration fromObject converts and scales time units accurately
- Interval fromDateTimes creates valid intervals and accurately determines containment and overlap
