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
- assert TestSuite discovers and counts test methods from TestCase class
- assert TestResult tracks execution count, failure count, and error count for test runs
- assert TestCase setUp and tearDown lifecycle hooks execute before and after test methods
- assert org.junit.Assert verifies equality, boolean conditions, nullness, and array equality
- assert org.junit.Assert.fail throws AssertionError on mismatch
