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. difflib.Diff computes element-by-element diff records between two string sequences
  2. difflib.Common indicates elements present in both sequences
  3. difflib.LeftOnly indicates elements unique to the first sequence
  4. difflib.RightOnly indicates elements unique to the second sequence
  5. difflib.DiffRecord String formats delta indicator and payload
  6. difflib.HTMLDiff formats string sequence differences into HTML table rows
