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. getDefaultWatermarks returns default percentage thresholds of 50 and 80 for statements, functions, branches, and lines
  2. createContext initializes a reporting context with default directory 'coverage' and default watermarks
  3. createContext applies custom reporting directory, customized watermarks, and custom sourceFinder
  4. Context.classForPercent classifies percentage values into low, medium, or high buckets according to configured watermarks
  5. Context.classForPercent returns unknown for unrecognized metric keys
  6. Context.getSource delegates to sourceFinder function to retrieve file content
  7. ReportBase executes report traversal across coverage tree invoking onStart, onSummary, onDetail, onSummaryEnd, and onEnd lifecycle methods
