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

Contract
- type-fest package.json defines package name as type-fest and version as 0.13.1 with types entry point
- type-fest index declarations export Merge, MergeExclusive, and RequireAtLeastOne symbols
- Merge type definition combines two types overriding keys of the first type with the second type using Except and Extract
- MergeExclusive type definition creates mutually exclusive key union type using Without helper
- RequireAtLeastOne type definition creates type requiring at least one key while keeping remaining keys optional
