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. FlagSet.SetNormalizeFunc installs a custom name normalizer that maps alternative flag name variations during lookup and parsing.
  2. FlagSet.Lookup retrieves flag definitions using either the original or normalized flag name variants.
  3. FlagSet.Parse matches command-line arguments written with underscores to flags registered with hyphens and sets their values correctly.
  4. FlagSet.GetNormalizeFunc returns the active normalization function, allowing direct invocation for custom name translation.
