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
- After redefining a typed method without adding a new `sig`, `T::Private::Methods.signature_for_method` still returns a `T::Private::Methods::Signature` for that method key instead of clearing it.
- The retained signature object is the same object that was cached when the method was first declared and still reports an Integer return type.
