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 fresh Ruby process started with `RUBYOPT=-rset` starts normally and can construct `Set`, while the same process started with `RUBYOPT=-rsorted_set` exits before executing the script body with `cannot load such file -- sorted_set`.
- This runtime resolves `set` as `1.1.1`, so the startup failure is caused by the missing `sorted_set` preload, not by an unexpected `set` version.
