▸ Magik
Rebuilding the FreeCAD-wasm PySide binding stack with NATIVE wasm exceptions (new-EH / try_table, -fwasm-exceptions -sWASM_LEGACY_EXCEPTIONS=0) to match the JSPI + wasm-EH toolchain (qt-jspi is try_table). Mixed EH => invalid module, so EVERY C++ archive must be new-EH with ZERO 'U invoke_' symbols. Env: source /opt/toolchains/emsdk/emsdk_env.sh AND export LD_LIBRARY_PATH=/home/magik6k/lcad-wasm/pyside-port/libshim (host shiboken6 needs the libclang shim). Working dir /home/magik6k/lcad-wasm/pyside-port. The build scripts there ALREADY have the new-EH flags applied. QtCore was already rebuilt new-EH (build/m2-qtcore/, validated). VERIFY each output archive: (a) it exists + has its PyInit symbol; (b) new-EH: emnm <archive> | grep -c 'U invoke_' MUST be 0 (invoke_ = JS-EH leftover = fail); (c) optional: extract one .o, link 'int main(){}' + the .o with 'em++ -fwasm-exceptions -sWASM_LEGACY_EXCEPTIONS=0 -sJSPI -sERROR_ON_UNDEFINED_SYMBOLS=0' and node -e 'WebAssembly.validate(...)' == true. Report the archive path, PyInit symbol presence, invoke_ count (must be 0), and pass/fail. BUILD the QtWidgets binding new-EH (needs QtGui's freshly-rebuilt gen dir). Run: cd /home/magik6k/lcad-wasm/pyside-port && MOD=QtWidgets \ TYPESYSTEM=/tmp/pyside-setup/sources/pyside6/PySide6/QtWidgets/typesystem_widgets.xml \ GLOBALH=/home/magik6k/lcad-wasm/pyside-port/globals/QtWidgets_global.h \ XGENINC="/home/magik6k/lcad-wasm/pyside-port/build/m2-qtcore/gen/PySide6/QtCore /home/magik6k/lcad-wasm/pyside-port/build/qtgui/gen/PySide6/QtGui" \ bash build-module.sh -> build/qtwidgets/libQtWidgets_wasm.a (PyInit_QtWidgets, 194 wrappers). VERIFY 0 invoke_. Report.

thinking
I'll start by exploring the environment and understanding how the build is set up.
Fable
I'll start by verifying the environment and the QtGui gen dir dependency, then run the QtWidgets build.

Now let me run the QtWidgets build in the background since it compiles ~194 wrappers.
