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. modfile.Require parses direct and indirect dependencies with correct module path, version, and indirect flag
  2. modfile.File.AddNewRequire adds a Require entry with the specified path, version, and indirect status
  3. modfile.File.DropRequire removes the matching Require entry by module path
  4. modfile.File.SetRequire replaces all Require entries and formats consistently on round-trip parsing
