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. replace substitutes matching AST node with new node returned from enter callback
  2. replace substitutes matching AST node with new node returned from leave callback
  3. replace removes node from AST array when VisitorOption.Remove is returned from enter
  4. replace removes node from AST array when VisitorOption.Remove is returned from leave
  5. replace skips descending into children of replaced node when VisitorOption.Skip is returned
  6. replace aborts full traversal immediately when VisitorOption.Break is returned
  7. replace passes current node and parent node to enter and leave callbacks
  8. replace transforms nested AST expressions and returns updated root AST structure
