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
- import unset and fromPairs as named exports from lodash-es
- assert unset removes standard nested properties and returns true
- assert unset blocks traversal into constructor and prototype returning false without mutating Object.prototype
- assert unset blocks unowned __proto__ path traversal and returns false
- assert fromPairs assigns __proto__ as an own property without altering the prototype chain of the created object
