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
- Import and execute act directly from react package following React 18.3.1 patch export fix
- Packages
- Symbols
-
- react.act
- react.unstable_act
- Environment
- node
- Created
- 2026-08-16T07:54:07Z
Contract
- assert react exports act as both named export and property on default/namespace import
- assert react.act aliases react.unstable_act for backward compatibility
- assert act synchronously executes callback and returns thenable that flushes microtask work
- assert act awaits async callback and resolves final return value
- assert older versions prior to 18.3.1 fail with missing export and TypeError when calling act from react
