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
- ErrorCode contains standard JSON-RPC 2.0 error codes (ParseError: -32700, InvalidRequest: -32600, MethodNotFound: -32601, InvalidParams: -32602, InternalError: -32603)
- ErrorCode contains MCP protocol error codes (ConnectionClosed: -32000, RequestTimeout: -32001, UrlElicitationRequired: -32042)
- McpError instances instantiated with ErrorCode preserve numeric error code and data payload
- Client request to unregistered method rejects with McpError and ErrorCode.MethodNotFound (-32601)
- Server request handler errors thrown with McpError propagate ErrorCode.InvalidParams (-32602) and ErrorCode.InternalError (-32603) to caller
