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 store and retrieve key-value pairs while respecting maximum capacity by evicting least recently used entries
- LRUCache peek inspects cached values without updating the recency order
- LRUCache has and del verify existence and delete individual entries from the cache
- LRUCache forEach and rforEach iterate entries in most-recently-used and least-recently-used order
- LRUCache keys and values return arrays of keys and values in order from newest to oldest
- LRUCache dump and load serialize the cache state and restore entries into a separate cache instance
- LRUCache dispose callback is triggered when an entry is evicted due to capacity or deleted
- LRUCache reset removes all entries and resets cache length and itemCount to 0
