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.

Case
HOW- Goal
- Unmocking a transitive dependency dynamically under Jest's module system requires both removing the mock definition via dontMock and invalidating the parent's require cache via resetModules.

Contract
- jest.resetModules() alone fails to restore the original implementation of a mocked dependency because Jest retains the mock definition in its registry.
- Calling jest.dontMock() to remove the registry entry and jest.resetModules() to clear the parent require cache successfully restores the original dependency.
