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
- assert `renderToString` removes an empty `src` attribute from `<img>` output
- assert `renderToString` removes empty `src` and `href` attributes from `<script>` and `<link>` output
- assert `renderToStaticMarkup` applies the same empty-attribute filtering rules as `renderToString`
- assert anchor `href=""` is preserved by both SSR APIs
