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
- type-fest package.json defines package name as type-fest and version as 0.21.3 with types entry point
- type-fest base declarations export Except, SetOptional, and PackageJson symbols
- Except type definition is declared as strict Pick-Exclude utility restricting omitted keys to target object keys
- SetOptional type definition combines Except and Partial-Pick to make specified keys optional
- PackageJson type definition exports structured declarations including Scripts, DirectoryLocations, and Person
