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 @freeze_time with as_arg=True executes sync functions twice due to an unbranched else clause in _call_with_time_factory, failing required positional arguments with TypeError on the second call
- assert @freeze_time with as_kwarg passes the time factory once on sync functions but wrap_coroutine silently drops as_kwarg on async coroutines
- assert @freeze_time with as_arg=True passes the time factory once to async coroutines without double execution
- assert @freeze_time on a class wraps public methods but skips __init__, private methods, staticmethods and classmethods which continue reading the real host clock
- assert auto_tick_seconds advances the clock by its step duration on every read of datetime.now(), time.time(), date.today(), time.monotonic(), and time.time_ns()
- assert generator and callable time_to_freeze arguments are evaluated once upon entering the freeze rather than dynamically on each clock read
- assert tick=True unfreezes time passage to real-time progression from the frozen start rather than stepping in fixed increments
