What it does
- A stable identity, not a throwaway cluster id. Every entity gets a stable entity_id (UUIDv7) that persists across runs as new data arrives. Records are absorbed, entities merge or split, but the id an entity earns is the id downstream syste
- Whole-record provenance. Every field of the golden record traces back to the source record that won it: which source, when it was last seen, and which survivorship strategy picked it. The values it *didn't* pick stay visible rather than bei
- Governed by construction. Conflicting values collapse to one best value by an explicit survivorship policy (most-complete · source-priority · most-recent · majority-vote); every identity change lands in an append-only event timeline; and th
