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
- LRUCache get and set operations retrieve cached values and respect maximum capacity (max) by evicting the least recently used entries
- LRUCache maxAge configuration expires entries after duration while allowStale and prune manage stale item retrieval and cleanup
- LRUCache length calculation tracks weighted item sizes and triggers eviction when total length exceeds max capacity
