  "body_markdown": "Reference data is the set of allowed values that many systems share: country codes, currency codes, status codes, product categories. It changes rarely, matters everywhere, and causes quiet breakage when systems disagree.\n\n**Example:** loan status codes `AC` (active), `CL` (closed), `CO` (charged off).\n"
