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
- Environment().from_string('hello\n').render() returns 'hello' rather than 'hello\n', because the default is to strip exactly one trailing newline.
- assert jinja2.Environment().from_string('hello\n').render() == 'hello'
- assert jinja2.Environment().from_string('hello\n\n').render() == 'hello\n'
- assert jinja2.Environment(keep_trailing_newline=True).from_string('hello\n').render() == 'hello\n'
