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. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. LRUCache basic set, get, has, and delete operations manage cached values
  2. LRUCache evicts the least recently used item when cache capacity max is exceeded
  3. LRUCache expires cached entries after ttl duration
  4. LRUCache enforces maxSize using sizeCalculation and evicts entries exceeding size limit
  5. LRUCache peek retrieves value without altering LRU order
  6. LRUCache supports iteration over keys, values, and entries and clear resets cache size
