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. inspector.New constructs an Inspector from parsed AST files for node filtering and traversal
  2. inspector.Preorder traverses AST nodes in preorder filtering by specific node types
  3. inspector.WithStack traverses AST nodes maintaining the ancestor stack and allowing branch control
  4. intsets.Sparse performs insertion, membership testing, union, and difference operations on sparse integer sets
  5. analysis.Analyzer defines a modular static analysis pass with metadata and execution function
