TxnEntityChanges Interface
The frontend transaction-change payload for onElementsChanged and onModelsChanged.
Iterate TxnEntityChanges to inspect their id, type, and metadata, or use filter to select by change type or class hierarchy.
Both payloads include metadata. Frontend changes also expose a per-change type, while backend changes are grouped into inserts, deletes, and updates; the compressed inserted, deleted, and updated sets remain available for bulk operations.
