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
- send(req, path, { root }) streams static files with Content-Type, Content-Length, ETag, Last-Modified, and Accept-Ranges headers
- send(req, path, { root }) returns HTTP 304 Not Modified when If-None-Match matches ETag
- send(req, path, { root }) returns HTTP 206 Partial Content with Content-Range header for byte range requests
- send(req, path, { root, maxAge }) sets the Cache-Control max-age header
- send(req, path, { root }).on('headers', fn) allows setting custom headers before streaming
- send(req, path, { root }) emits an error with status 404 when the file does not exist
- send(req, path, { root, dotfiles: 'deny' }) emits an error with status 403 for dotfiles
