 - `ai_call_logger` caller registry：registry 匯入失敗仍不阻擋 LLM 遙測，但已改為 warning + stack。
 - Observability route：promotion review RAG 相似查詢、PPT audit history 缺表、host health probe 寫入、MCP 24h summary 缺表等 fail-safe 區塊已改成 debug/warning log，不再完全靜默。
 - Google Drive import：`services/import_service.py` 的日期 `IN (...)` 刪除/驗證查詢已改為 SQLAlchemy bind params，不再把 DataFrame 日期值拼進 SQL 字串。
+- OpenClaw Bot：中文字型下載、趨勢同期 DB 查詢、匯入格式業績預覽解析等 best-effort 區塊已補 debug/exception/warnings，避免真正錯誤完全無跡可查。
