Top-level properties

Property	Type	Required	Notes
entity	string	yes	Entity Engine entity name the rows belong to. Must already exist (ship it in metadata/entities/ if the plugin owns it).
keyFields	array	yes	The natural-key fields that uniquely identify a row. On re-install, a row matching all keyFields is updated (only if a non-key value changed); otherwise inserted. Never produces duplicates.
source	string		The plugin id. Stamped into a seeded_by field when the entity has one.
rows	array	yes	The rows to upsert. Each is a plain field map for the entity - no tenant id (the installer supplies it).
