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
- Carbon::createFromTimestamp() defaults strictly to UTC (+00:00) rather than inheriting date_default_timezone_get(), shifting local wall-clock hours unless timezone is explicitly specified
- diffInDays(), diffInMinutes(), and diffInSeconds() return float values with fractional precision (e.g. 18 hours = 0.75 days, 45 seconds = 0.75 minutes) rather than integer-truncated 0 values
- diffIn* without absolute flag returns signed negative floats when comparing against earlier timestamps
- Carbon::setTestNow() defensively clones the mock date argument, preventing subsequent in-place mutations on the original date variable from altering the active test clock
- CarbonPeriod::getStartDate() returns a protected date instance whose external mutation does not alter the period boundary
- Carbon::minValue() and Carbon::maxValue() are removed and throw UnknownMethodException
