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. UnifiedDiff struct configures line diff comparison with source and target line slices, file names, timestamps, and context line count
  2. GetUnifiedDiffString generates unified diff formatted text including file headers, hunk range metadata, deletion prefixes (-), insertion prefixes (+), and surrounding context lines
  3. GetUnifiedDiffString returns an empty string when the compared line sequences are identical
  4. WriteUnifiedDiff formats and writes unified diff text with tab-separated timestamp headers directly to an io.Writer
  5. UnifiedDiff with Context set to 0 outputs hunk modifications without surrounding context lines
