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.

HOW- Goal
- Test Guzzle requestAsync timing with MockHandler: delay blocks before promise return, on_stats is deferred until wait and observes a 500 response before http_errors rejects, transport throwables become handler error data, and invalid on_stats is rejected eagerly.

Contract
- assert MockHandler applies a numeric delay synchronously before Client::requestAsync returns while the returned middleware promise and on_stats callback remain pending
- assert waiting the promise invokes on_stats exactly once with the same response, effective URI, synthetic 0.0 transfer time, empty handler stats, and no handler error data
- assert on_stats observes a fulfilled 500 response with null handler error data before http_errors rejects wait with ServerException over the same response
- assert a queued transport throwable yields no response, is preserved as handler error data, and is rethrown as the same object by wait
- assert non-callable on_stats throws InvalidArgumentException at the Client::requestAsync call site before returning a promise or consuming the MockHandler queue
