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. spew.Sdump formats primitives, structs, and nested pointers with full type information and field names
  2. spew.ConfigState with DisablePointerAddresses omits pointer memory addresses from dump output
  3. spew.ConfigState with SortKeys produces deterministic sorted output for map entries
  4. spew.ConfigState with MaxDepth limits traversal depth of nested structures and emits max depth reached
  5. spew.Fdump writes formatted deep dumps directly to an io.Writer
  6. spew.Sprintf formats structs using spew-specific verbs such as %#+v with type annotations
