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
- assert visit traverses AST nodes and mutates scalar values in-place within a YAML Document
- assert visit removes mapping pairs and sequence items when returning visit.REMOVE
- assert visit replaces AST nodes when returning a new Scalar from visitor callback
- assert visit stops further traversal immediately when returning visit.BREAK
- assert visit skips child node traversal when returning visit.SKIP
- assert visitAsync asynchronously traverses and mutates Document AST nodes with async visitor callbacks
