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

  2. micromatch.braces expands brace patterns into all string permutations when expand option is true
  3. micromatch.braces expands numeric and alphabetical range patterns
  4. micromatch.braces expands nested brace pattern structures
  5. micromatch.braces deduplicates expanded permutations when nodupes option is enabled
  6. micromatch.braces returns original input in array when no braces are present or input is empty
  7. micromatch.braces throws TypeError when the pattern argument is not a string
