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 environmentMatchGlobs is ignored in Vitest 4 and test files without docblocks default to node environment
- assert per-file @vitest-environment happy-dom docblocks initialize window and document before setupFiles execute
- assert @vitest-environment node docblocks override project-level happy-dom configurations back to node
- assert setupFiles execute sequentially in array index order within each isolated test file context
- assert globals:false leaves describe, it, expect, and vi undefined on globalThis while preserving DOM globals in happy-dom
- assert globals:true exposes describe, it, test, expect, and vi globally without explicit imports
