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
- Resolve io() URL pathnames as namespaces rather than HTTP paths, multiplex distinct namespaces over a shared Manager and transport, isolate namespace disconnections, and transmit auth payloads within packet 40 rather than HTTP handshake headers

Contract
- assert io() parses URL pathname as socket namespace and routes HTTP requests to /socket.io/ rather than URL path unless path option is explicitly set
- assert io() calls sharing the same origin reuse a single Manager instance and underlying transport connection unless forceNew is true
- assert disconnecting one multiplexed namespace leaves sibling namespaces and the underlying Manager transport connection open
- assert auth option is transmitted inside Socket.IO packet 40 payload rather than HTTP handshake query parameters or headers
- assert socket.emit returns the socket instance for chaining while socket.timeout on a disconnected socket begins immediately and rejects with operation has timed out
