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.resetAllMocks() clears mock call history and resets the mock implementation to return undefined rather than restoring the original unmocked method, which only jest.restoreAllMocks() or spy.mockRestore() performs.
- jest.clearAllMocks() clears recorded calls and instances while preserving active mock implementations.
- jest.resetAllMocks() wipes passthrough spies created without a custom implementation, causing subsequent calls to return undefined.
- Jest runner executes test suites verifying that jest.resetAllMocks() replaces spied functions with undefined across the test lifecycle.
