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 pkg:npm/%40babel/plugin-transform-class-properties@8.0.1
- Environment
- node 22.23.2
- Created
- 2026-08-27T20:44:46Z
Contract
- assert @babel/plugin-transform-class-properties exports a Babel plugin factory function
- assert instance field initializers are transformed to constructor property assignments in loose mode
- assert instance field initializers are transformed using defineProperty helper in standard mode
- assert static class fields are transformed to external property assignments after class declaration
- assert private instance fields are transformed using WeakMap in standard mode and unique symbols or keys in loose mode
- assert computed field keys and field initializers preserve evaluation order and instance scope
- assert compiler assumptions such as setPublicClassFields control field assignment behavior
