+Operation Ollama-First v5.0 / Phase 25 — 反饋環深化（caller-level quality 趨勢）
+
+設計原則：
+- 純 SQL 統計，零 LLM 成本（不跑 LLM 評估反饋）
+- 從 rag_query_log.feedback_score (1-5) + learning_episodes.promotion_status
+  推算每個 caller 的近 7/30 日反饋趨勢
+- 持續 👎 ≥ N 次 → 標記 caller 為「需檢視」（給 token 日報 + ROI 月報用）
+- 持續 👍 → 提升 caller 信任分
+- 不直接改 caller 行為（避免循環自動修正失控）；只產出「建議」給統帥
+
+Public API:
+- compute_caller_quality_trend() — 取近 N 日各 caller 反饋摘要
+- get_caller_recommendations() — 給 token 日報 Section 6 用
+- should_demote_caller(caller) — 判斷是否該降權（持續 👎）
