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. TestPathPatterns can be constructed with pattern strings and correctly reports isSet, isValid, toPretty, and toJSON
  2. TestPathPatterns reports isValid as false when given an invalid regex pattern
  3. TestPathPatternsExecutor created from empty patterns matches any absolute path within or outside rootDir
  4. TestPathPatternsExecutor matches paths against relative pattern strings against rootDir
  5. TestPathPatternsExecutor correctly handles patterns with leading dot-slash prefix matching relative to rootDir
