pub const UNATTRIBUTED_PRODUCT_ID: u32 = 0;Expand description
The csg_failures key used for records that belong to no single product:
the boolean processors’ own logs (swept once per element by
crate::GeometryRouter::drain_processor_failures) and
PENDING_MAPPED_BOOL_FAILURES. Zero is not a valid IFC express id, so it
cannot collide with a real product.
