SyncChange class

One row in a SyncEnvelope.

tableName is the local table name (matches EntityMeta.tableName). pk is the primary key value (serialised as a String for transport). payload is the row data (a Map<String, Object?> of column names to values) — for delete changes, this is null. version is a monotonically increasing number (e.g. a millisecond timestamp) used for last-write-wins conflict resolution.
