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. RequestVarsReplacer expands http.vars placeholders set via context variables
  2. RequestVarsReplacer evaluates standard HTTP request placeholders including method, host, header, and query parameters
  3. VarsMiddleware sets context variables and expands nested placeholders in variable values
  4. VarsMatcher correctly matches requests based on variable values and placeholder criteria
  5. SetVar with nil value removes the variable from the request context and replacer returns empty string
