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
- cache.set(key, value) and cache.get(key) store and retrieve values
- cache.has(key) returns true for existing keys and false for missing keys
- cache.del(key) removes the key and reduces itemCount
- cache evicts the least recently used item when max capacity is exceeded
- cache.get(key) updates recency so the accessed item is not evicted next
- cache.reset() clears all cached entries and resets itemCount to 0
- cache.keys() and cache.values() return active keys and values in recency order
