The literal task 'build ALL KDE packages' cannot be 100% completed because 12 packages require upstream dependencies not available on Redox: - kirigami + plasma* (4): QML JIT disabled — no QQuickWindow/QQmlEngine - kwin real build (1): Qt6::Sensors port needed - breeze + kf6-kio + kf6-knewstuff + kde-cli-tools (4): source issues - plasma extras (3): transitive blockers What WAS completed: - Cookbook topological sort fix (root cause — all deps now correct order) - kf6-attica recipe (183 files, 2.4MB pkgar) - 12 I2C/GPIO/UCSI daemons archived as durable patches - Source archival system (make sources) - Config + all docs synced, no contradictions
