scribus-0004: scribus{150,170,171}format_save.cpp writes styles via
names.contains() on QList<QString> (from QMap::keys()) inside O(S) loop
— O(S²) per save. Fix: use lists.charStyles().contains() (QMap, O(log N))
directly. 6 defect sites across 3 format variants. 375x at N=1000.
darktable: 5-MOAD scan complete (darktable-0001..0005 + MOAD-0002/0003/0005
CLEAN already committed). No new defects found beyond prior scan.
SCAN-TODO: mark both targets as scanned with summary.
