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. txtar.Parse parses txtar-formatted byte data into an Archive with comment and file entries
  2. txtar.Format serializes an Archive back into byte data preserving file boundaries and content
  3. astutil.Apply traverses AST nodes invoking pre and post functions and allows node inspection
  4. astutil.AddImport adds an import specification to an AST file
  5. astutil.DeleteImport removes an existing import specification from an AST file
  6. astutil.RewriteImport rewrites import path from old path to new path in an AST file
