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
- Yallist creates a doubly linked list from an iterable array of elements
- push and unshift insert elements at tail and head updating length
- pop and shift remove elements from tail and head returning their values
- toArray returns an array of list elements in order
- removeNode removes a specific node from the list and updates pointers
