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.Parse parses a go.mod file into a File struct with module path and Go version
  2. modfile.File.AddRequire adds a required dependency module path and version to the modfile
  3. modfile.Format formats a modfile.File AST back into standard go.mod formatted bytes
  4. modfile.File.DropRequire removes an existing requirement from the modfile AST
  5. modfile.File.AddReplace adds a module replace directive to the modfile AST
  6. modfile.Parse returns an error when parsing malformed go.mod content
