qmc2

• Path: arch/maintained/qmc2
• Build failure during the 2026-07-07 “build all packages for x86_64” private-repo release pass. Needs qt5-webengine, not in this arch/ tree – same as memory/kchmviewer.md/memory/qt5-webview.md (external-dependency class, see memory/dbmodel-qt4.md). Not fixed as part of this pass.
• 2026-08-02: deliberately deferred, not attempted – qt5-webengine needs a full Chromium source checkout+build (qtwebengine-chromium submodule), and available disk at the time was only ~22GB free, too tight to risk a multi-hour build failing partway through. Skip this one until there’s real headroom (30GB+ free is a safer bet) or a dedicated session for it.
