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
- Structs containing PhantomPinned without #[pin] or #[project(!Unpin)] silently implement Unpin, allowing safe Pin::get_mut
- Fields annotated with #[pin] PhantomPinned or structs declared with #[project(!Unpin)] correctly inhibit Unpin
- project_replace returns PhantomData for pinned fields to prevent moving pinned values
- PinnedDrop executes safely on pinned struct drop
