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
- start_blocking_portal context manager runs an async event loop in a background thread
- BlockingPortal.call executes an async coroutine from synchronous thread and returns the result
- BlockingPortal.start_task_soon spawns a concurrent async task inside the portal event loop
- BlockingPortal.wrap_async_context_manager adapts an async context manager for use in synchronous threads
- BlockingPortal cleans up and stops the portal background thread upon exit
