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.

Case
HOW- Goal
- verify findUpStop in pkg:npm/find-up@5.0.0
- Packages
- Symbols
-
- findUpStop
- Environment
- node 22.23.2
- Created
- 2026-08-26T11:17:29Z
Contract
- assert findUpStop is exported and equals findUp.stop symbol
- assert findUp halts asynchronous directory traversal and resolves to undefined when matcher returns findUpStop
- assert findUp.sync halts synchronous directory traversal and returns undefined when matcher returns findUpStop
- assert returning findUpStop at initial search directory halts traversal immediately without checking parents
- assert createStopAtDirectoryMatcher stops synchronous traversal at boundary marker
- assert createAsyncStopMatcher stops asynchronous traversal at boundary marker
- assert directory traversal continues upward to find target when findUpStop is not returned
