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
- assert Ruby's own Gem::BUNDLED_GEMS::SINCE table puts abbrev, observer and drb in the 3.4.0 wave, ostruct, benchmark and logger in the 4.0.0 wave, and set on no wave at all
- assert a library from the wave that already landed raises LoadError naming it unless the Gemfile declares it, while the declared one loads and lands its Array monkeypatch
- assert Ruby emits the add-it-to-your-Gemfile notice through Warning.warn and still raises the LoadError in the same run
- assert a library from the next wave loads without a Gemfile entry but warns about 4.0.0, and stays absent from the resolved bundle
- assert declaring a default gem is a real version pin, because the interpreter's own copy still exists and the Gemfile decides which one runs
- assert Set resolves through the bundle by autoload, with no require anywhere
- assert an OpenStruct key overwrites the method it collides with, so class returns the data, method stops taking an argument, and only [] and to_h read safely
- assert OpenStruct overwrites __send__ too, warning that this may cause serious problems, and then refuses an argument
- assert a missing OpenStruct key reads as nil through both accessors while to_h.fetch raises KeyError
- assert Set dedupes by eql? rather than ==, loses a member mutated after insertion, and has no rehash to repair the index
