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
- Passing a function to form action or button formAction in react-dom/server emits a javascript:throw error URL and injects an inline submit listener replay script
- Passing a string URL to form action renders the string attribute verbatim and omits the reactFormReplay script
- useFormStatus during server rendering always returns pending false, data null, method null, and action null across parent and child components
- react-dom/server transforms controlled select value props into selected attributes on matching child options while stripping value from select
- react-dom/server renders controlled textarea value props as inner text content and strips the value attribute from the textarea tag
- react-dom/server strips suppressHydrationWarning attributes from server-rendered markup while preserving boolean data and aria attributes
