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 setSignedCookie signs and attaches cookie with HMAC-SHA256 signature to context response
  2. assert setSignedCookie supports cookie options such as path, maxAge, httpOnly, secure, and sameSite
  3. assert setSignedCookie supports secure and host cookie prefixes with __Secure- and __Host- names
  4. assert getSignedCookie verifies and extracts valid signed cookie value
  5. assert getSignedCookie returns false when cookie signature is tampered or verified with incorrect secret
  6. assert getSignedCookie returns undefined when requested signed cookie is not present
