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.
MIT-0

Contract
- assert InMemoryTransport.createLinkedPair links client and server communication in-process
- assert Client.connect executes automatic initialize handshake, emitting initialized notification and populating getServerCapabilities
- assert Client.registerCapabilities and Client.connect throw if invoked on an already connected client instance
- assert callTool returns content array and resolves with isError true rather than throwing for application tool errors
- assert server McpError preserves explicit ErrorCode while unhandled exceptions are mapped to ErrorCode.InternalError
- assert requests exceeding timeout reject with ErrorCode.RequestTimeout and DEFAULT_REQUEST_TIMEOUT_MSEC is 60000ms
- assert pending in-flight requests reject with ErrorCode.ConnectionClosed when the transport is closed
