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
- A Viper instance using delimiter `::` returns `db.local` for `service::db::host`, and `Sub("service")` also returns `db.local` for `db::host`.
- When delimiter-specific lookup on the sub-tree works, it proves `Sub()` preserved lookup behavior instead of silently falling back to parentless key parsing.
