  "description": "Paper validation: every rule from the reference rule_engine_instruction.txt (ids 1–17) expressed in the generic model. Stage slugs carry the reference rule id in a comment-style suffix. Notable translation choices: (a) reference 'manual' rules (9–12) are separate stages against the RAW source so they see rows the primary chain never saw — matching the reference semantics; (b) all the manual SQL preprocessing (LPAD, RIGHT(card,4), unit renames, quote stripping) lives in the templates' normalize steps, not here.",
