Maintainers will ask what the Design tab costs before they will look at the diff, so measure it rather than assert it. The headline correction: the OCCT delta is THREE toolkits, not two. The comment in deps/OCCT/OCCT.cmake claimed "TKFillet + TKOffset (3.77 MiB, Windows only)". Walking OCCT's own adm/MODULES and each toolkit's EXTERNLIB shows ModelingAlgorithms holds twelve toolkits, that eight of them are built either way because DataExchange (the STEP path upstream already ships) depends on them, and that the true delta is TKFeat, TKFillet, TKOffset and TKXMesh — of which TKXMesh is never produced. So three archives are built: 7.40, 5.38 and 4.42 MiB. TKFeat is the interesting one. Nothing in the Design tab references it and it is absent from the TKFillet/TKOffset dependency closure, so it is built for nothing — OCCT's module flag is all-or-nothing per module. On static-link platforms that is build time and zero shipped bytes. Two numbers are deliberately absent, marked as absent, and not approximated: the Windows DLL delta needs a Windows build (snaporca-gix), and a clean-build time delta needs the deps prefix built twice on one machine. The old 3.77 MiB figure is withdrawn rather than reused — it covered two of the three toolkits. Also recorded: the vendored solver is 9,339 lines under GPLv3 with its LICENSE preserved, which combines into this AGPLv3 fork without difficulty (AGPLv3 §13), and it is live code driving every sketch constraint — not a carried corpse.
