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. deleteCookie sets Set-Cookie header with empty value, Max-Age=0, and default path /
  2. deleteCookie returns the existing cookie value from incoming Cookie header
  3. deleteCookie applies options including path, domain, secure, httpOnly, sameSite, and partitioned
  4. deleteCookie handles secure prefix by prepending __Secure- and setting Secure attribute
  5. deleteCookie handles host prefix by prepending __Host-, setting Secure attribute, and ignoring domain
  6. multiple deleteCookie calls append multiple Set-Cookie headers on response
