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
- When Settings.defaultZone is overridden, Info.normalizeZone('system') and DateTime.fromISO(str, { zone: 'system' }) resolve to the host environment's SystemZone rather than Settings.defaultZone, while 'default' resolves to Settings.defaultZone instead of creating an invalid DateTime.
- Info.normalizeZone('system') equals SystemZone.instance and does not equal Settings.defaultZone when defaultZone is changed
- Info.normalizeZone('default') equals Settings.defaultZone and is valid
- DateTime.fromISO with zone 'system' produces a valid DateTime with zoneName equal to SystemZone.instance.name rather than Settings.defaultZone
- DateTime.fromISO with zone 'default' produces a valid DateTime with zoneName equal to Settings.defaultZone
- DateTime#setZone('system') resets zone to SystemZone.instance.name while DateTime#setZone('default') resets zone to Settings.defaultZone
