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. assert ignore() creates and returns an Ignore instance
  2. assert ignore.isPathValid validates relative paths and rejects invalid, absolute, or non-string inputs
  3. assert Ignore#add registers gitignore rules from strings, arrays, and other Ignore instances with method chaining
  4. assert Ignore#ignores returns true for ignored paths and false for non-ignored or negated paths
  5. assert Ignore#filter filters an array of file paths and returns only unignored paths
  6. assert Ignore#createFilter returns a predicate function suitable for Array#filter matching Ignore#filter behavior
  7. assert Ignore#test returns an object with { ignored, unignored } boolean flags reflecting matching gitignore rules
  8. assert ignore with ignorecase option controls case sensitivity in rule matching
  9. assert ignore with allowRelativePaths option accepts relative paths with leading dot-slash
