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
- expect.extend registers synchronous custom matchers returning { pass, message } that support standard and negated .not assertions and throw assertion errors with the custom message on mismatch
- expect.extend registers asynchronous custom matchers returning a Promise resolving to { pass, message } for awaiting promise expectations
- Custom matchers registered via expect.extend can be used as asymmetric matchers within toEqual structural assertions
- Custom matchers receive execution context on this including this.isNot and this.utils formatting helpers such as matcherHint, printExpected, and printReceived
