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 gettz('') returns a tzinfo instance, not None
- assert gettz('') matches gettz() default local timezone
- assert gettz(':') returns the local timezone
- assert gettz() with empty TZ env var returns the local timezone
- assert datetime.now(gettz('')) produces a timezone-aware datetime
