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

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. websocket.NewConfig creates a valid WebSocket configuration with URL, Origin, and protocol version
  2. websocket.Handler converts a function into an http.Handler that serves WebSocket connections
  3. websocket.Dial establishes a WebSocket client connection to a server with specified origin
  4. websocket.Message.Send and websocket.Message.Receive transmit and receive text string payloads
  5. websocket.Message.Send and websocket.Message.Receive transmit and receive binary byte payloads
  6. websocket.JSON.Send and websocket.JSON.Receive serialize, transmit, and deserialize structured data
