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
- assert intervalToDuration omits zero-value duration units instead of populating zeros
- assert intervalToDuration returns signed negative units for inverted intervals instead of throwing RangeError
- assert intervalToDuration returns an empty object for invalid date inputs without throwing RangeError
- assert isWithinInterval and areIntervalsOverlapping silently normalize inverted intervals instead of throwing RangeError
- assert eachDayOfInterval returns a descending date array for inverted intervals instead of throwing RangeError
- assert roundToNearestMinutes returns Invalid Date on out-of-range nearestTo without throwing RangeError
