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 @wrapt.lru_cache on an overridden subclass method calling super().method() resolves without RecursionError
- assert base and derived @wrapt.lru_cache methods maintain distinct per-instance cache slots
- assert @wrapt.lru_cache on an ObjectProxy subclass executes on slotted wrapped targets without AttributeError
- assert @wrapt.lru_cache on an ObjectProxy stores cache state on the proxy without polluting the wrapped __dict__
- assert multiple ObjectProxy instances wrapping the same target maintain isolated per-proxy caches
