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
- JestHook isUsed reports false initially and true when a listener is registered for a hook
- JestHook emitter onFileChange invokes all registered onFileChange subscribers with the file system object
- JestHook emitter onTestRunComplete invokes all registered onTestRunComplete subscribers with the aggregated results
- JestHook emitter shouldRunTestSuite returns true when no listeners are registered or when all listeners return true
- JestHook emitter shouldRunTestSuite returns false when any sync or async listener returns false
- TestWatcher tracks watch mode and initial uninterrupted state
- TestWatcher setState updates interrupted state and emits change event
- BaseWatchPlugin provides default plugin lifecycle methods and KEYS defines standard ANSI key sequences
