Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. assert ignore() creates and returns an Ignore instance
  2. assert Ignore#add registers gitignore rules from strings and arrays and supports method chaining
  3. assert Ignore#ignores returns true for ignored paths and false for non-ignored or negated paths
  4. assert Ignore#filter filters an array of file paths and returns only unignored paths
  5. assert Ignore#createFilter returns a predicate function suitable for Array#filter matching Ignore#filter behavior
  6. assert Ignore#test returns an object with { ignored, unignored } boolean flags reflecting matching gitignore rules
