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 context manager enables programmatic clock manipulation via move_to and tick, applies tz_offset strictly to local time without altering UTC, and restores outer scopes upon exit
- assert calling tick() without arguments advances the frozen clock by exactly 1 second while tick(delta) supports int, float, and timedelta increments
- assert move_to() immediately updates datetime.datetime.now() and datetime.datetime.utcnow() to the specified string, datetime, or date target
- assert tz_offset shifts datetime.datetime.now() while datetime.datetime.utcnow() and time.time() remain bound to the unshifted UTC timestamp
- assert nested freeze_time context managers cleanly override the frozen clock in inner blocks and restore outer frozen state on exit
- assert FakeDatetime and FakeDate instances returned during time freezing maintain full inheritance and isinstance compatibility with datetime.datetime and datetime.date
