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. readline.NewPrefixCompleter builds a completion hierarchy and returns expected completion suggestions for prefixes
  2. readline.NewEx initializes a readline instance with custom configuration
  3. readline.Instance.Readline reads input lines accurately from configured stream
  4. readline.Instance.SetPrompt updates the prompt string
  5. readline.Instance.Close releases readline instance resources cleanly without error
