  "summary": "The meaning should survive when the colour does not.",
  "kind": "checklist",
  "body": "Add a meaningful label, symbol, pattern or other non-colour cue. Keep that cue consistent and understandable in context. This addresses colour dependence; contrast, accessible names and text alternatives still need their own checks.",
  "limits": [
    "An unexplained icon can be as ambiguous as a colour. Do not assume that adding any symbol makes the information accessible."

  "example": "A reconciliation table replaces red-only rows with an Error status and a short reason, while retaining colour as an optional aid.",
