Detailed Description

One atomic modification event recorded in the graph's history log.

A HistoryRecord captures what happened during a single call to BRepGraph::ApplyModification():

• OperationName identifies the algorithm ("Sewing", "FilletEdge", ...).
• SequenceNumber provides total ordering of events.
• Mapping records the topological fate of each affected node: original -> [replacement1, replacement2, ...] (split) original -> [same_node] (modified in place) original -> [] (deleted)

The history log is append-only within a graph's lifetime.
