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