The 2026-06-21 assessment was written before the persistence work landed and got two load-bearing facts wrong. Both are corrected here against the branch itself rather than from recollection: 1. It called OCCT "a dependency mainline OrcaSlicer has never carried" and built its whole conclusion on that. False: deps/OCCT/ exists at the merge-base, and upstream already links it from Format/STEP.cpp, Format/svg.cpp and Shape/TextShape.cpp. The real dependency diff is one line -- BUILD_MODULE_ModelingAlgorithms OFF -> ON -- costing a measured 3.77 MiB of Windows DLLs (TKFillet + TKOffset; TKBool already arrives transitively via DataExchange). 2. It described the vendored SolveSpace solver as LGPL. False: src/libslic3r/slvs/LICENSE is GPL-3.0. Harmless for us, but a licence must not be misstated in a document aimed at upstream. It also claimed no changes to Model, which stopped being true when 3MF recipe persistence added a std::string there. The rewrite replaces prose estimates with counted figures: 138 new files, 23 modified upstream files at +457/-75, nothing deleted, 99.3 % of the diff in new files. That reframes the ask from "adopt a CAD kernel" to "widen a build flag you already carry", which is the argument that actually has a chance upstream.
