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 Container#index returns 0-based index of child Node in Root container
  2. assert Container#index returns 0-based index of Declaration or Comment in Rule container
  3. assert Container#index returns numeric argument as-is when number is passed
  4. assert Container#index returns -1 when target node does not belong to the container
  5. assert Container#index resolves index correctly for proxy-wrapped nodes and parsed AST children
