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
- anyio.from_thread.BlockingPortal allows synchronous external threads to call async coroutines in the portal event loop and synchronously obtain results
- anyio.from_thread.BlockingPortal.start_task_soon schedules concurrent background tasks in the portal event loop without blocking synchronous callers
- anyio.from_thread.run executes an async coroutine in the event loop thread from a worker thread spawned via anyio.to_thread.run_sync and returns its result
- anyio.from_thread.run_sync executes a synchronous callable in the event loop thread from a worker thread
