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. goutils.Abbreviate returns the original string unchanged when string length does not exceed maxWidth
  3. goutils.Abbreviate returns an error when maxWidth is less than 4
  4. goutils.Abbreviate handles empty string input when maxWidth is valid
