* io/xref.rs — replaced the 7-line "BlockRecord::is_loaded turned out to be unreliable" rationale with a one-liner. The reverted experiment lives in git history (e88a946,0996b75). * refedit::RefEditSession.insert_handle — set at construction but never read; the "kept for future REFCLOSE DISCARD" TODO can come back via git history when that feature lands. * scene::mod — dropped the placeholder MeshModel re-export; nothing outside `mesh_model` consumes the bare name and MeshLodSet is the pipeline-facing type now.
