Dual-fork mandate: port the parametric-recipe 3MF persistence from snaporca-cad commits ed19eac+147e1c4 so a saved project reopens with the editable CAD feature tree, not just the baked mesh. Shared kernel/format/GUI (identical to snaporca-cad): - CadDocument serialize_recipe/deserialize_recipe (cereal BinaryArchive, versioned) + CadFeature split save/load + imported_solid<->BRep string. - Model::cad_recipe carried through 3MF zip entry Metadata/SnapOrca_cad.bin (writer + binary-verbatim reader branch). - DesignPanel on_commit() stamps the recipe; on_tab_shown() rehydrates a loaded project via load_recipe() (deserialize -> feed_bodies + refresh_tree). Mainline-only adapters (no snaporca-cad counterpart — Catch2 v3 vs v2): - tests/libslic3r/test_caddocument.cpp: <catch2/catch_all.hpp> + `using Catch::Approx;` (v3 scopes Approx under Catch::). - tests/libslic3r/CMakeLists.txt: register test_caddocument.cpp (the original CAD port had left it out of the test build). Verified on behemoth (snaporca-deps toolchain): libslic3r_tests clean; [CadDocument] 17/18 (only the pre-existing tangent-to-circle SIGABRT fails, identical to snaporca-tkz); K1 serialize round-trip + version-reject pass (13 assertions); new [3mf] "CAD recipe blob survives a 3mf save/load cycle" passes byte-for-byte; orca-slicer GUI links clean (186/186, DesignPanel.cpp compiled). Interactive :10 click-through pending (no Design-tab automation). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01BVzKmX6Y1aEteit1HTXG4Q
