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
- assert iterating over EventSource(response) yields ServerSentEvent instances from a text/event-stream response
- assert ServerSentEvent parses custom event types, last event ID, retry interval, and multiline data payloads
- assert ServerSentEvent.json() deserializes JSON payloads from the event data field
- assert EventSource raises SSEError when response Content-Type is not text/event-stream
- assert EventSource raises SSEError when a single event exceeds max_event_size
