A .rdbview is a zip of model.rdb/ (the lossy IFC data DB — the rdb serializer skips IfcRepresentationItem) + model.ifcview (baked geometry). The viewer could produce them but not open them. - extractRdbview(): unzip a .rdbview (QZipReader) into a session temp dir keyed by a hash of path+mtime+size (reused on re-open), returning the extracted model.rdb. The producer's layout means sidecarPath(model.rdb) resolves the sibling model.ifcview automatically, so it then loads exactly like any pure .rdb: geometry from the sidecar, data from the .rdb via ifcopenshell::file(FT_AUTODETECT). No SceneLoader/engine changes. - detail::loadModels() resolves each source path through it before queueModels (both fresh-open and project reload go through here), so the Federation persists the .rdbview while the loader gets the extracted .rdb. - cleanupRdbviewCache() clears stale extractions at startup. - .rdbview is offered under "Add Geometry" (the file picker; "Add IFC Database" is a directory picker), not "Add IFC File" — it's a lossy viewer bundle, not a source IFC.
