Golden record
A synthesized canonical record produced by merging the contributing source rows for one real-world entity.
A golden record represents one customer (or vendor, or product) and pulls its field values from the underlying source rows that the entity resolution engine determined refer to the same real-world entity.
A golden record is not just "pick a system and trust it." Each field gets its value via a survivorship rule — "most recent updated" for contact info, "highest source priority" for legal name, etc. The record carries lineage back to every source row it summarizes, so any field can be traced + audited.
The number of golden records is always less than or equal to the number of source rows (because duplicates collapse into one). The ratio of source rows to golden records is one of the engine-quality signals operators watch over time.
