+## 📍 2026-04-24 — ADR-092 P0+P1+P2.1 全修（commit 7f4088b / 04ff225 / bb5f16f）
+
+### P2.1 修復（commit bb5f16f）
+- **consensus_engine.py**: 四 ExpertAgent confidence=0.0 → 加權投票 total=0 → 永遠 NO_ACTION；改為依訊號強度 0.45~0.80
+- **consensus_engine.py**: `_normalize_action` 加「重新啟動」別名 → 正確歸 RESTART；移除未使用 _target
+- **prompts.py**: 新增 Evidence-First Protocol + Skepticism Rules（要求 LLM 引用 `<raw_evidence>` 才能高 confidence）
+- **openclaw.py**: `analyze_alert` 提取 `diagnosis_context` → `<raw_evidence>` 注入 full_prompt
+- 驗證：CrashLoop 測試 consensus score 從 0.0 → 0.744
+
+### 🔴 手動 DB Migration 待執行
+```bash
+psql $DATABASE_URL -f apps/api/migrations/adr092_p1_learning_chain_fix.sql
+```
+
+### 剩餘 P2 工作
+- P2.4: Telegram 中間態推播（editMessageText 佔位卡）
+- P2.6: trust_drift_detector 接入 ai_slo_watchdog_job
+
+---
+
 ## 📍 2026-04-24 — 12 Agent 全景審計 + P0-P2 全面並行修復
