Data Fields inherited from BRepGraphInc::BaseDef
uint32_t	OwnGen = 0
	Own-data mutation counter, incremented ONLY when the entity's own definition fields change (tolerance, point, flags, etc.). NOT incremented by descendant changes. Used by VersionStamp for persistent identity staleness detection.

uint32_t	SubtreeGen = 0
	Subtree mutation counter, incremented when own data OR any descendant data changes. Propagated upward via markParentSubtreeGen(). Used by TransientCache and shape cache for hierarchical freshness.

uint32_t	LastPropWave = 0
	Wave counter from the last propagation that visited this node. Used as a re-visit guard in markParentSubtreeGen() to prevent exponential blowup on diamond topologies. Compared against BRepGraph_Data::myPropagationWave.

bool	IsRemoved = false
	Soft-removal flag.

Detailed Description

Product entity: reusable shape definition (part or assembly). Children are managed uniformly via OccurrenceRefIds:

A part product has one occurrence whose ChildDefId is a topology root node.
An assembly product has occurrences whose ChildDefId values are other products. Products carry no location or orientation - those live on references.
