CH column metadata: esios.archives_i90.owner_quality

# `esios.archives_i90.owner_quality` Attribution provenance enum: direct_yaml | direct_omie | representante_unresolved | unknown. Always populated. Articles aggregating by owner_group should consider source-trust per row. - **category**: dimension - **common_pitfalls**: - `representante_unresolved` rows have agent_group set (the representante) but owner_group NULL — the real owner is unknown - `direct_omie` reflects OMIE LISTA_UNIDADES `AGENTE PROPIETARIO` column — for utility-direct UPs this matches the asset owner, but for representante-operated UPs (Amorebieta/Castleton) OMIE may report the representante as 'propietario'. Trust `direct_yaml` over `direct_omie` when both are available; curate the YAML to override OMIE when external evidence (corporate filings, news) contradicts it. - Default article narrative SHOULD distinguish: aggregate `direct_yaml` separately, treat `direct_omie` as best-effort, report `representante_unresolved` + `unknown` as residual
