Every change creates a new version instead of overwriting prior state. Earlier snapshots remain queryable, so you can answer what the system believed at any point.
Before vs after
Before: a row update erases the old value unless you added custom history tables. After: each correction is appended as a new observation, so historical state is preserved by default.
# Current snapshot
neotoma entities search --query "Ana Rivera" --entity-type contact
# Historical lineage
neotoma observations list --entity-id <entity_id>
This aligns with event-sourcing principles: the observation log is authoritative, snapshots are derived views. See
