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
- event.listen registers listener function on Engine target and event.contains confirms registration
- event.remove unregisters listener function from Engine and raises InvalidRequestError when removing non-registered listener
- event.listens_for decorator registers listener function on Engine target for before_cursor_execute
- event.listen with named=True passes event arguments as keyword arguments to listener function
- event.listen with retval=True allows listener function to transform executed SQL statement and parameters
- event.listen and event.remove register and unregister ORM Session class-level event listeners
