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. sign generates a signed JWT string with three base64url-encoded segments for a given payload and secret
  2. decode parses token header and payload without verifying signature
  3. verify validates token signature and returns the payload, rejecting invalid secrets or tampered tokens
  4. jwt middleware authenticates requests with valid Bearer token and injects jwtPayload into context
  5. jwt middleware rejects requests with missing or invalid Bearer tokens with 401 Unauthorized
