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. Queue initializes empty with size 0 and peek returning undefined
  2. enqueue adds items to queue and increments size
  3. dequeue removes and returns items in FIFO order until empty
  4. peek returns the next item without removing it
  5. clear resets queue to empty size 0
  6. Queue instance is iterable with for...of and spread without mutating queue
  7. drain yields and removes all items in FIFO order until queue is empty
