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
- Comparing Equatable objects containing maps with disjoint keys like {'keyA': null} and {'keyB': null} evaluates to false because missing keys are checked with containsKey rather than resolving to null.
- Equatable props map comparison correctly checks key existence when values are null.
