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
- jest.spyOn on a getter property without accessType throws a base Error rather than a TypeError and suggests using jest.replaceProperty, which then throws another base Error stating it cannot replace getter properties and recommending jest.spyOn(object, property, 'get').
- jest.spyOn(object, getterName) throws an Error instance where err instanceof TypeError is false
- jest.replaceProperty(object, getterName, value) throws an Error instance recommending accessType 'get'
- jest.spyOn(object, getterName, 'get') successfully creates a getter mock that permits mockReturnValue
