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
- BaseReporter is a constructible class providing lifecycle hooks and error management
- CustomLifecycleReporter subclasses BaseReporter to capture onRunStart, onTestStart, onTestCaseResult, onTestResult, and onRunComplete events
- BaseReporter exposes getLastError and manages internal errors recorded via _setError
- utils.formatTestPath formats test file paths relative to project root configuration
- utils.relativePath splits test path into dirname and basename based on root configuration
- utils.getSummary formats test suite and snapshot counts from aggregated results
- utils.getSummary throws when showSeed is true but seed is undefined
