污染修復情況（2026-08-11）

修復方式：污染掃描（詞庫驅動，/data/sdg_data/sdg_pipeline/lexicon/lexicon.yaml）→ scan-triage 逐筆人工判讀「真污染 / 誤報」→ 只修真污染；簡繁/大陸用語為逐詞判讀替換，非 OpenCC 整篇轉換（避免把已正確的繁體改壞）
修復範圍：僅修改 assistant 角色內容（user/tool/system 未動，訓練時本就被 mask）
本次修復筆數：污染清理 25 筆 + 「方程→方程式」用語修正 128 處
完整逐筆 before/after 對照：見 cleanup_0811_before_after.jsonl（污染清理）、fangcheng_fix_0811.jsonl（方程→方程式）
