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. semver.NewVersion parses semantic version strings and extracts major, minor, patch, prerelease, and build metadata components
  2. semver.StrictNewVersion parses strictly formatted versions and rejects invalid versions or leading v prefixes
  3. semver.NewConstraint validates whether versions satisfy range constraints and returns validation error lists
  4. semver.Collection sorts a slice of versions in ascending semantic precedence order
  5. semver.Version increment methods IncMajor, IncMinor, and IncPatch increment segments, reset lower fields, and clear prerelease metadata
