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. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. send(req, path, { root, index: 'home.html' }) serves the custom index file when requesting a directory
  2. send(req, path, { root, extensions: ['html', 'txt'] }) serves the file with a matching extension when omitted from the request path
  3. send(req, path, { root, immutable: true, maxAge: 86400000 }) includes the immutable directive in the Cache-Control header
  4. send(req, path, { root, acceptRanges: false }) omits the Accept-Ranges header and ignores Range request headers
  5. send(req, path, { root, cacheControl: false, etag: false, lastModified: false }) suppresses Cache-Control, ETag, and Last-Modified response headers
  6. send(req, path, { root, dotfiles: 'ignore' }) emits a 404 Not Found error when accessing dotfiles
  7. send(req, path, { root, index: false }).on('directory', fn) emits the directory event when requesting a directory with index disabled
