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
- Server class is exported and instantiates with metadata and capabilities
- Server connects to Client via InMemoryTransport and completes handshake
- Server tool handlers process tools/list and tools/call requests
- Server prompt handlers process prompts/list and prompts/get requests
- Server resource handlers process resources/list and resources/read requests
- Server sends tool list changed notifications to client
- Server rejects requests for undeclared capabilities with standard MCP method not found error
