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. intsets.Sparse stores non-negative integers and supports bitset operations including union, intersection, difference, and membership testing
  2. astutil.PathEnclosingInterval finds the path of AST nodes enclosing a specified source interval from innermost node to root file
  3. inspector.New constructs an AST inspector supporting type-filtered traversal with Preorder, Nodes, and WithStack methods
  4. typeutil.IntuitiveMethodSet computes all methods associated with a type including pointer receiver methods for value types
