【全景檢測：12-agent 並行掃描定位 4 大 bug 與 1 個 P0 連鎖回歸】

Bug 1（P0 silent failure）— governance_agent.check_trust_drift
  原 `await db.commit()` 縮排錯在 async with 區塊外（8 空格 vs 12），
  session 已 auto-commit 關閉，二次 commit 拋 InvalidRequestError 被吞，
  governance_trust_drift_auto_deprecated log 從不出現。修：commit/log 移回 with 內。
  附 AST regression guard test 擋退化。

Bug 2 — flywheel_stats_service / W-3 fresh deploy 假告警
  Redis 空時 total_exec=0 → rate=0.0 → watchdog `< 0.30` 立即觸發
  「飛輪成功率 0%」假告警。修：total_exec < FLYWHEEL_MIN_SAMPLE(10) 回 None，
  watchdog 判 None 跳過 W-3。Prometheus sentinel 用 NaN（非 -1.0）
  避免觸發 ops/monitoring/alerts.yml:775 等 3 份 prom rule 的 `< 0.1`
  條件造成 2h 後假告警連鎖。前端 type 同步 number | null。

Bug 3 — failover_alerter dedup key
  原 key 只看 event_type 不看 payload，trust_drift 4→25 IDs 變動全被
  1h dedup 吞掉。修：dedup key 加 sha256(impact subdict)[:8]，event_type
  sanitize 防特殊字元污染 Redis key。

Bug 4 — ai_slo_watchdog_job W-4 evolver 全封存初始化誤報
  原邏輯 approved==0 即告警，未排除「playbooks 表初始化中」場景。
  修：_count_approved_playbooks 回 (approved, total)，total==0 → skip。

【執行結果】
- 39 個相關 unit test 全過（test_failover_alerter / test_governance_agent /
  test_trust_drift_watchdog / test_check_trust_drift_commit_outside_context_poc）
- 6 個關鍵路徑實測：NaN sentinel / float 渲染 / hash 區分性 / dedup 同 impact
  相同 hash / datetime 容錯 / 4 檔 py_compile 全過

【調度教訓 — 留作未來改進】
- 12-agent 並行調度時，vuln-verifier 與 fullstack-engineer 競態
  導致 vuln-verifier 讀到已修代碼誤判 NOT REPRODUCIBLE。
  未來：vuln-verifier 應在 fullstack 之前執行，或用 git show HEAD~1 對比修復前。
- fullstack-engineer 引入 P0 regression（f-string 內嵌 ternary 非法 format spec），
  critic 抓到 + Prom sentinel 連鎖 — 證明 critic 審查必要不可省。

trust_drift previously fired alerts forever for playbooks stuck below
the 0.2 threshold. With user authorization for governance-class
auto-fixes, check_trust_drift now retires playbooks that have been
unused for 30+ days (or never used and created 30+ days ago) by
flipping status to 'deprecated' before alerting.

Alerts now report drifted_count, auto_deprecated_count, and the kept
playbook_ids that still need human review (those in their 30d trial
window). Existing alert noise from the four currently-drifted
playbooks should drop to whatever fraction is genuinely in trial.

c5753e1c57 fix(critic-review): KMWriter 名實統一 + Alertmanager 修抑制 + drift checker AST 化 
critic PR review 揭示已 push commits 的 7 個 blocker，本 commit 全部修復。

## C1 + C2 + M1 + M2 + M3 — KMWriter 真正統一契約（critic 最嚴重 5 條）

### C1 km_writer.py:194 — backfill 自打臉修
- 裸 asyncio.create_task(_backfill_path_a_approval) → await _backfill_path_a_approval_safe()
- 同步 await + 獨立 DLQ km:backfill:dlq + try/except 不阻塞主寫入
- 新增 km_backfill_reconciler_job.py（每 5 分鐘掃 DLQ）+ ENABLE_KM_BACKFILL_RECONCILER flag
- 防 Path B 比 Path A 先完成 → related_approval_id 永遠 NULL 的 race

### C2 km_writer.py:391 — KM_WRITE_AWAIT=false 路徑收緊
- 從 ensure_future（fire-and-forget 比舊版同步寫更糟）
- 改 await writer.write(retry=1, timeout=2.0)（仍 await 但只試一次、超時短）
- docstring 明確標註「緊急回滾用，不保證可靠性」

### M1 decision_manager.py:2178/2203 — 移除 _fire_and_forget 旁路
- 兩處 _fire_and_forget(executor.write_execution_result_to_km(...))
- 改 await asyncio.shield(...) + BaseException 保護（防上層 cancel 中斷）
- KM_WRITE_AWAIT=true 在這條路徑終於真正 await

### M2 incident_service.py:1099 — 自製 path 加 retry+DLQ
- 原本 if settings.KM_WRITE_AWAIT: await asyncio.wait_for else create_task
- 改 3 次指數退避 retry + DLQ 保護（呼叫 km_writer 私有 helper）

### M3 km_writer.py:166 — 冪等聲明對齊實作
- knowledge_repository.create() 加 UPSERT 路徑（pg_insert ON CONFLICT DO UPDATE）
- KnowledgeEntryCreate / KnowledgeEntryRecord 加 path_type 欄位
- migration: ADD COLUMN path_type + partial unique index uix_knowledge_incident_path

## M4 alertmanager.yml — equal: [] 收緊（critic 防爆炸抑制）
- OllamaInstanceDown / KMConverterDown 抑制加 equal: ['cluster'] 約束
- 防多 cluster 場景下任一 Ollama down 誤抑全 AI/SLO 告警

## M5 Alertmanager 版本驗證（已確認 v0.31.1，遠超 v0.22+）

## M6 governance_agent.py — health score 區分 skipped vs ok vs violated
- check_slo_compliance 加 _meta {violated_count, skipped_count, ok_count, all_skipped, status}
- run_self_check: SLO 全 skipped 時獨立發 governance_slo_data_gap 告警
  （不污染 self_failure 計數，因為 no_data 是 emitter 未實作不是治理機制故障）

## M7 scripts/check_config_drift.py — 改 AST 解析
- regex 改 ast.parse 找 Settings ClassDef AnnAssign Field(default=...)
- 避免多行 list / default_factory= / 含跳行字串的 false negative
- 4 欄位（AI_FALLBACK_ORDER / ARGOCD_URL / PROMETHEUS_URL / OLLAMA_URL）全對齊

## 新增測試
- test_km_writer_backfill_reconciler.py: 7 cases（C1 reconciler + safe helper）
- test_km_writer_idempotent.py: 5 cases（M3 path_type 注入 + UPSERT 分支）

## 驗證
- 1585 unit tests 全綠（+13 從 1572）
- amtool check-config SUCCESS（8 inhibit_rules / 2 receivers）
- drift checker AST-based 4 欄位全對齊
- Alertmanager v0.31.1 確認支援新語法

## 期望影響
- KMWriter 名實統一：飛輪閉環 KM 寫入路徑 100% 可靠
- M4 抑制爆炸風險解除
- 治理層不再對 SLO no_data 靜默
- drift checker false negative 風險解除

715dc3cb91 fix(observability): P0 假警報止血 + ConfigMap drift 對齊 + 治理工具 
12-Agent 全景診斷觸發的 P0/P1 觀測層修復。

## P0 假警報止血（4 SLO 雪崩根因）
- governance_agent.py:306 — 空 result 不再 fallback 0.0，改 continue + log warning
  根因：Prometheus 查無資料（emitter 未實作 / rule 未部署）被誤判為 SLO=0
  必觸發 violated=True 噴 4 條假告警

## P0 鬼魂按鈕守門
- telegram_gateway.py:1654 — LLM 動態按鈕 Redis 失敗時 btn_list.clear()
  first_row（批准/拒絕，HMAC nonce 無狀態）由 caller 1488 永遠保留
  feedback_no_ghost_buttons.md 三缺一鐵律對齊

## ConfigMap drift 修復（3 處）
- config.py:683 PROMETHEUS_URL: 188→110（drift checker 揪出 = SPF-4 部分根因）
- config.py:705 ARGOCD_URL: 125→121（T0 G3 已知）
- config.py:375 AI_FALLBACK_ORDER: 補 nvidia 對齊 ConfigMap

## P1 Alertmanager 升級（amtool SUCCESS）
- ops/alertmanager/alertmanager.yml: deprecated → v0.27+ 新語法
  - match/match_re → matchers
  - source_match/target_match → source_matchers/target_matchers
  - group_by 加 team label（防 SLO 雪崩 4 條同秒推）
  - PostgreSQL/Redis inhibit 補 equal: ['instance']（防爆炸抑制）
- 新增 3 組因果抑制：
  - OllamaInstanceDown → SLO_*/AI_*（30 分鐘）
  - KMConverterDown → SLO_KMGrowthRate*
  - SLO_*_FastBurn → SLO_*_(Medium|Slow)Burn

## 治理工具落地
- scripts/check_config_drift.py: ConfigMap vs code default drift 檢測
  揪出 PROMETHEUS_URL drift 是 SPF-4 根因（governance_agent 連 188 而非 110）
- scripts/health_check_session.sh: 11 服務 + 4 SSH + drift + git 全景驗證

## 驗證
- 1552 unit tests 全綠
- amtool check-config SUCCESS（8 inhibit_rules / 2 receivers）
- drift checker 4 欄位全對齊
- health check 11 服務全可達

ed205489c1 feat(p3.2-tests+ci-schema): model_version 測試 + CI test_schema 對齊 + Grafana SLO Dashboard
Some checks failed
CD Pipeline / build-and-deploy (push) Failing after 1m20s
Details 
P3.2 配套測試 + CI 環境同步 + ADR-100 Grafana 視覺化：

CI test_schema 補齊（解 1162-1172 阻塞之延伸）:
- setup_test_schema.sql 加 ai_provider_version_history 表
- 對齊 production p3_2_provider_version_history.sql（已 K8s exec 上線）

新增測試 (636 行):
- test_model_version_probe.py (387) — Provider 探測單元測試
- test_model_version_tracker.py (249) — Tracker 整合測試
  · 4 個 DB-dependent tests 標 @pytest.mark.integration
  · 15 unit + 4 integration（unit step 跳過 integration class）

新增配套:
- ai-slo-dashboard.json (496 行) — Grafana 儀表板
  · 對應 ADR-100 SLO 規則的 4 大面板：
    自主修復成功率 / 飛輪閉環延遲 / 治理事件 / Provider 健康度

修改:
- governance_agent.py +122 行 — SLO 指標暴露 + retrieve metric 整合

Tests: 15 passed (probe + tracker unit), 4 deselected (integration class)

Production 部署狀態:
- p2_decision_fusion_columns.sql ✅ K8s exec 完成（commit c58bdd0c）
- p3_2_provider_version_history.sql ✅ K8s exec 完成（this commit）
- 兩個 production migration 都已上線，CI test_schema 同步補齊

cc547736ab feat(wave6-8): P2.1 fusion + P2.2 governance + P2.4 consensus + Wave 7/8 BLOCKER 修復 
承接 Wave 6/7/8 多 engineer 在 agent 限額前完成的代碼，補 commit 解 production
HEAD 隱性 import error（decision_fusion 已被 decision_manager 引用但檔案 untracked）。

新增（後端核心）:
- decision_fusion.py (562 行) — P2.1 方法 III（OpenClaw + Hermes + Elephant 三 LLM 融合）
- aiops_timeline.py + aiops_timeline_service.py — critic B4 修復
  /api/v1/aiops/timeline endpoint，DB 存取抽到 service 層遵守 leWOOOgo 積木化
- migrations/p2_decision_fusion_columns.sql + rollback — approval_records fusion 欄位

修改（後端整合）:
- decision_manager.py — fusion 三斷鏈修補（critic B1+B2+B3）：
  · B1: 寫 _evidence_snapshot_ref 到 token.proposal_data
  · B2: fusion 前計算 complexity_score 並寫 token
  · B3: fusion composite 寫 token.proposal_data["decision_fusion"]
- auto_approve.py — fusion + consensus 認識（critic B3+B5）：
  · composite > 0.7 → auto_execute_eligible bypass min_confidence
  · source=consensus_engine + score>=0.6 → 規則可信路徑
- consensus_engine.py — db-fix _save_consensus 重用 agent_sessions
- governance_agent.py — db-fix _alert PG 寫入 ai_governance_events
- approval_db.py — fusion 3 欄位 + 2 partial index + CheckConstraint
- db/models.py — schema 對齊 migration
- core/config.py — vuln #1 修復：OLLAMA_URL/_FALLBACK_URL field_validator
  拒絕公網 IP + 外部域名，僅允許私網/loopback/K8s SVC 白名單
- core/feature_flags.py — P2 fusion + consensus flags
- main.py — governance_agent lifespan 啟動
- failover_alerter.py — Wave8-X2: in-memory dedup fallback（Redis 拒絕後不 fail-open）
- ollama_*.py — metrics 整合 + recovery 改善
- auto_repair_service.py — verifier 接線

新增（測試 2438 行）:
- test_decision_fusion.py / test_governance_agent.py / test_consensus_integration.py
- test_p2_db_fixes.py / test_wave8_fusion_fixes.py
- test_config_url_validation.py（vuln #1 12 tests）
- test_failover_alerter.py +Wave8-X2 in-memory dedup 補測

驗收: 116 tests pass (decision_fusion + wave8_fusion + config_url + consensus +
                      governance + p2_db_fixes + failover_alerter)

Conflict resolution:
- 3 檔（config.py + auto_approve.py + decision_manager.py）git stash pop 衝突
  保留 stashed (engineer 最終版)，補回 ValueError 「公網 IP」字樣對齊 test

Note: 此 commit 解 production HEAD 隱性 import error
仍未修: vuln #4 prompt injection / debugger B14 quota fail-closed
       / B25-B26 drain_pending_tasks / B8 governance fail alert

2c57b71db9 feat(wave5-p2): GovernanceAgent 4 項自檢 + Ollama 健康告警規則 + Prometheus metrics 整合
All checks were successful
CD Pipeline / build-and-deploy (push) Successful in 10m45s
Details 
MASTER plan_complete_v3.md Wave 5 P2.2 + P2.3 完成（multiple engineers 在限額前完成代碼，補 commit）：

P2.2 — GovernanceAgent 4 項自檢:
- governance_agent.py (342 行) — 每 1 小時自檢循環:
  · trust_drift（信任度漂移檢測）
  · knowledge_degradation（知識退化檢測）
  · llm_hallucination（LLM 幻覺檢測）
  · execution_blast_radius（執行爆炸半徑檢測）
- main.py lifespan: asyncio.create_task(run_governance_loop()) 啟動
  try/except 包裹，schedule 失敗不阻斷主流程
- failover_alerter.py: alert_governance(event_type, payload) 1h dedup
  四類事件 → Telegram MarkdownV2 告警

P2.3 — Ollama 健康規則 + Prometheus Metrics:
- ops/monitoring/ollama_health_rules.yaml (148 行):
  · OllamaHealthDegraded / OllamaPrimaryDown
  · OllamaFailoverTriggered / GeminiQuotaExceeded
  · 補 Prometheus 取資料的 alert rules
- core/metrics.py (57 行):
  · GEMINI_DAILY_CALL_COUNT / GEMINI_DAILY_QUOTA Gauge
  · OLLAMA_FAILOVER_TRIGGERED_TOTAL Counter
  · OLLAMA_CURRENT_PRIMARY_IS_OLLAMA Gauge
- ollama_failover_manager.py:
  · _check_gemini_quota: 每次 check 同步更新 Gauge（讓 Prometheus 取最新值）
  · select_provider: failover 時 inc Counter + 切 Primary Gauge
  · try/except 包裹，metric 失敗不阻斷主路由

E2E 測試:
- test_failover_e2e_dispatch.py (365 行)
  完整 dispatch 路徑：health check → failover decide → alerter → metrics

Tests: 54 passed (e2e_dispatch + failover_manager + failover_alerter)
