Nodes this run added inside a container: a new container's own subtree, and children merged into a container already on canvas. Undone before the top-level nodes, so nothing is left orphaned in the graph.
Edges this run added.
Top-level nodes this run added.
The nodes the pivot was run on. Empty for an origin-less pivot, and what a save payload carries as "which event does this attach to".
OptionalrestageWhat this ingest took out of the staged set. Only the newest ingest is ever re-staged, so this is a record of what could be restored rather than a promise that it will be.
How many of this run's elements have been written to the source system — nodes, children and edges together. A surface reads it to warn before an undo rather than after: undo takes things off the canvas and issues no compensating write, so what was saved stays saved upstream.
Children merged into a node already on canvas, so redo can merge them again.
Elements already on canvas that this run vouched for without adding.
One ingest, undoable as a unit. Holds the raw payload as well as the ids, so redo re-lands the recorded delta without refetching or re-gating.
