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 set and get operations retrieve cached values and respect maximum capacity (max) by evicting the least recently used entries
  2. LRUCache ttl configuration automatically expires entries after the specified duration while allowStale and purgeStale control stale item visibility
  3. LRUCache methods has, delete, clear, and peek allow querying and manipulating cache entries without disrupting LRU ordering
