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
- Calling `T.must(false)` returns `false`, proving `T.must` only rejects nil, while calling `T.must(nil)` fails.
- `T.must(nil)` raises `TypeError` in this version.
