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. ansi color constants like Reset, Red, Green, and LightBlue provide standard ANSI escape sequences
  2. ansi.Color formats strings with foreground color and style attributes, resetting at the end
  3. ansi.ColorCode returns ANSI escape sequence for composite foreground, background, and text attributes
  4. ansi.ColorFunc returns a reusable closure that applies precompiled ANSI color styling to strings
  5. ansi.DisableColors disables ANSI code generation and returns plain unstyled strings
