CC[100] flagged 28/38 qa_log rows with a literal 'n' where newlines should be, correctly declined to auto-fix given ambiguity. USR369 authorized fixing only the safe subset: 'n' immediately followed by a digit+period (clear numbered-list break pattern). Scanned all 38 rows, found 33 regex matches across 14 rows. Before applying, tested on row 27 first and caught a genuine false positive: 'python3.' matches the same n+digit+period shape but is a real word, not a stripped newline. Excluded row 27 entirely. Manually reviewed all remaining 32 matches with context to confirm each was a genuine numbered-list break, not another coincidental term. Fixed pattern also correctly handles doubled 'nn' (paragraph breaks) as two real newlines, not just single ones. Applied to 13 rows via 30-app-api.php action=update.
