One compact boundary inside `<devicesets>` was enough.+1.13.46's diagnosis (parts without a 3D package) was wrong: those parts add fine from a library broken into lines.+- `fusion_schematic_run`, `fusion_sch_place_part` and `fusion_sch_swap_part` rewrite a compact .lbr in place before+  USE: a line break between elements, nothing else (the element tree is compared before and after and nothing is+  written if it differs). In place, because a copy at another path under the same library name makes Fusion ask+  which one to take once both are in use. The reply says `libraryReformatted`. A file the bridge cannot write is+  refused (`library_not_writable`) with the reason.+- The `no_3d_package` refusal from 1.13.46 is removed.+- `fusion_schematic_run` still checks each ADD and stops at the first that did not land (`add_failed`), and an+  assertion during the run still fails it (`fusion_assert`).+ ## 1.13.46 (2026-10-31)  Issue #135, the real cause (checked live on Fusion 2706.1.14): ADD raises Fusion's PlacePartWorker `assetAdded`
