Whether a downstream compute pass writes the network's vertex buffer in place each cycle, so the geometry producer must keep restoring the CPU-authoritative vertex data every frame.

False by default. A GpuFieldOperator with bindings returns true: its VertexFieldProcessor adds a field onto the existing records (pos += f), a displacement from the uploaded geometry rather than an integrator, bounded only while the producer re-uploads the reference geometry every frame. NetworkGeometryProcessor suppresses its incremental / skip-when-clean upload path while any chain operator reports this. A later seed/render split gives the field pass its own reference and lifts the restriction.

Reimplemented in MayaFlux::Nodes::Network::GpuFieldOperator.
