AF178SI - la etiqueta del catalogo resuelve a un chasis distinto del que el vehiculo apunta, posible duplicado de catalogo

Candidate catalog defect surfaced as a by-product of the MOVILBA-574 measurement, filed separately because it is not the display question and must not be resolved by whichever way that one is ruled. Reported by coder04-mba-l-ca 2026-09-24 relaying the db measurement: among the rows where the catalog label and the book text differ in spelling, resolver-vs-FK agreement is 0 mismatches for the same propulsion EXCEPT one - dominio AF178SI, where the CATALOG LABEL ITSELF resolves, through rutap.chasis_resolver, to a chassis id different from the one the vehicle carries. That is a different shape from the other 733/734 rows: everywhere else the two strings are two spellings of one chassis, here the catalog's own text points at a second catalog row. ESTABLISH: (1) the vehicle's chasis_id, the catalog label behind it, and the id that label resolves to, in BOTH bases, with the fabricante and unidad_propulsora shown, since the chassis business key is the TRIPLE (fabricante_normalizado, modelo_normalizado, unidad_propulsora_id) and a fuel equivalence holds only WITHIN a fixed manufacturer; (2) whether the two catalog rows are genuinely two chassis or one duplicated - decided against the manufacturer's technical designation, NOT against the resolver, which cannot answer it: the resolver is what wrote the FK, so asking it whether the FK is right returns agreement no matter what the data quality is; (3) whether any OTHER vehicle points at either row, and how many. If it is a duplicate, the fix is a catalog decision with an owner and an id kept, not a silent re-point of one vehicle - and note that a hard DELETE of an opciones row strips the label from the _archive rows that reference it, with no FK to stop it, so count the _archive references BEFORE proposing any removal.
