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
- verify vitest.vi.fn and vitest.vi.spyOn mock functions in pkg:npm/vitest@3.2.7

Contract
- vi.fn() creates mock functions that track call arguments, return values, and call counts
- vi.fn() supports mockReturnValue and mockReturnValueOnce overriding return values
- vi.fn() supports mockResolvedValue and mockResolvedValueOnce for async mock resolution
- vi.spyOn() intercepts object methods while preserving initial behavior until overridden
- mockClear resets recorded calls and results while preserving custom implementations
- mockReset on vi.spyOn reverts to initial method implementation while keeping the spy active
- mockRestore detaches the spy and restores original method on the target object
