How this identity was established
The linked mentions were joined only after documentary name forms, place, role, date range and surviving business evidence were reviewed together. The local Neruda Archives authority remains primary; a brand, business lineage, historical firm and modern company are not treated as identical without exact supporting evidence.
Future corrections are recorded as new, sourced decisions rather than silently overwriting earlier evidence.
