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, set, has, delete, and clear operations manage key-value pairs with max capacity eviction and track cache size
- LRUCache ttl and purgeStale manage time-to-live entry expiration with allowStale option
- LRUCache maxSize with custom sizeCalculation calculates total entry size and evicts items when size limit is exceeded
- LRUCache dispose callback is invoked on entry eviction, deletion, and overwrite with key, value, and eviction reason
- LRUCache fetch method asynchronously retrieves and caches values with concurrent request deduplication
