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. assert CookieJar::extractCookies marks cookies without Domain attribute as HostOnly and prevents sending them to subdomains
  2. assert CookieJar::extractCookies marks cookies with explicit Domain attribute as not HostOnly and sends them to subdomains
  3. assert RedirectMiddleware truncates cross-origin Referer header to origin only when referer option is enabled
  4. assert RedirectMiddleware preserves full path and query in same-origin Referer header
  5. assert RedirectMiddleware completely removes Referer header on HTTPS to HTTP scheme downgrade redirects
  6. assert BodySummarizer restores response body stream cursor position after formatting error message during ClientException
  7. assert SetCookie strictly prioritizes Max-Age=0 over future Expires attribute to mark cookie as immediately expired
  8. assert UriComparator::isCrossOrigin canonicalizes IPv6 bracketed hosts and treats alternate representations as same-origin
  9. assert Client preserves explicit request method casing verbatim without automatic normalization
