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. expr.Constant represents typed constant values such as bool, int64, and string
  2. expr.Expr constructs abstract syntax tree nodes for expressions including ident and call
  3. expr.ParsedExpr holds parsed expression AST and source info serializable via protobuf
  4. expr.Type defines primitive, list, and map type specifications
  5. expr.CheckedExpr associates AST nodes with resolved types and reference maps
