fb0c72db42 feat(ai-router): 推翻 A2 鐵律 — DIAGNOSE primary 改 Ollama 本地優先
Some checks failed
CD Pipeline / build-and-deploy (push) Failing after 2m26s
統帥鐵律 2026-04-29:「主要優先用 111 主機的 Ollama」
+ feedback_ai_autonomous_direction.md:以本地免費 LLM 為主
+ feedback_ollama_111_only.md:Ollama 唯一主機 = 111

## 推翻 A2 (2026-04-27 INC-20260425) 的事實基礎

**舊事實**:Ollama = CPU-only deepseek-r1:14b @ 238s(不可用)
**新事實**:prod Ollama 111 = M1 Pro Apple Silicon GPU + qwen2.5:7b-instruct
           VRAM 8.2GB 全載入,ctx 32k,實測 hi prompt 0.54s

**雲端全死**(2026-04-29 prod log 證據):
- OpenClaw 188:8088 → 500 Internal Server Error
- Gemini → 429 Too Many Requests(配額爆)
- Claude → 404 Not Found(model claude-3-haiku-20240307 過期)

**不推翻 A2 → 100% incident llm_failed → AI 自動修復永遠不啟動**

## 修改範圍(最小、安全、可驗證)

### ai_router.py
- `_diagnose_fallback_chain`: OLLAMA 第一順位(取代「永久排除」舊註解)
  順序:[OLLAMA, OPENCLAW_NEMO, GEMINI, CLAUDE]
- `_intent_provider_overrides[DIAGNOSE]`: OPENCLAW_NEMO → OLLAMA
- 不動 _full_fallback_chain(避免影響 RESTART/SCALE/CONFIG/DELETE)
- 不動 _tool_calling_fallback_chain
- 不動 complexity_map(critic M2 留待後續)

### openclaw.py
- 注入 task_type="diagnose" 到 alert_context(critic C2 真根因)
- 修復 ai_providers/ollama.py:77 timeout 對齊問題:
  - 有 task_type → OLLAMA_DIAGNOSE_TIMEOUT_SECONDS=200s
  - 沒有 → OPENCLAW_TIMEOUT=30s(不夠 qwen2.5:7b 推理)
- prod log 看到 latency_ms=120014 的根因
- 用 dict(alert_context) 複製,不污染原 context

## Regression Test 同步更新(5 個)

A2 鐵律守門 test 全部反映新鐵律:

- test_p0_diagnose_routing.py::test_diagnose_override_is_ollama
  (原 test_diagnose_override_is_openclaw_nemo)
- test_ai_router_diagnose_fallback.py::test_diagnose_fallback_chain_ollama_primary
  (原 test_diagnose_fallback_chain_no_ollama)
- test_ai_router_diagnose_fallback.py::test_diagnose_route_primary_is_ollama
  (原 test_diagnose_route_fallback_chain_excludes_ollama)
- test_ai_router_diagnose_fallback.py::test_diagnose_route_sync_primary_is_ollama
  (原 test_diagnose_route_sync_fallback_chain_excludes_ollama)
- test_ai_router_diagnose_fallback.py::test_build_fallback_chain_for_intent_diagnose_with_ollama_primary
  (原 test_build_fallback_chain_for_intent_diagnose_no_ollama)
- test_ai_router_failover_integration.py::test_router_uses_failover_for_diagnose_ollama_primary
  (原 test_router_does_not_use_failover_for_openclaw_nemo)

每個 test docstring 都記載歷史脈絡 + 推翻原因。

## 驗證

- 1608 unit tests 全綠
- LLM 路徑 16 個 test 全綠(含 6 個 A2 守門 test 更新版)
- complexity_scorer / failover_manager / intent_classifier 不受影響

## 期望 prod 行為(部署後驗證)

incident 進入 → DIAGNOSE intent → primary OLLAMA (qwen2.5:7b on M1 Pro GPU)
  失敗才 fallback → OpenClaw 188 → Gemini → Claude
  Ollama 用 200s timeout(之前 30s 不夠)
  → AI 自動修復終於可以啟動,不再 100% llm_failed

## 已知債(後續處理)

- models.json:21 ollama.default 仍是 deepseek-r1:14b(critic C1,但 prod 已自動 route 到實載 model)
- complexity 4/5 仍寫死 gemini/claude(critic M2)
- Gemini API key 在 prod log 明文(需輪換 + sanitize)

fefe4c21cd fix(inc-20260425): A1+A2 後續 — Solver/Critic timeout + auto_repair 接線 + Runbook + Grafana
Some checks failed
CD Pipeline / build-and-deploy (push) Has been cancelled
延續 595629c0 INC-20260425 修復,補三段 Agent + 全鏈路觀測:

A1 後續 — Solver/Critic 三段 timeout 接線:
- solver_agent.py: AGENT_SOLVER_TIMEOUT_SEC=20.0(env override)
- critic_agent.py: AGENT_CRITIC_TIMEOUT_SEC=15.0(env override)
- protocol.py: 三 Agent 共用 observe_agent_step() 包裹呼叫
  · success/timeout/error outcome label
  · histogram 寫入 aiops_agent_step_duration_seconds

A2 後續 — auto_repair_service 改用 _diagnose_fallback_chain:
- auto_repair_service.py +46 行 — 切換 DIAGNOSE 路由到新 chain(NEMO→GEMINI→CLAUDE)
- 完全避開 Ollama CPU 238s 二次 timeout

新增 metrics:
- core/metrics.py +59 行 — 配合 observe_agent_step 的 histogram bucket + label cardinality

新增測試 (862 行):
- test_agent_step_timeouts.py (475) — 三 Agent 各 timeout 邊界 + outcome label
- test_ai_router_diagnose_fallback.py (387) — _diagnose_fallback_chain 正確序

新增配套:
- docs/runbooks/RUNBOOK-AGENT-STEP-LATENCY.md (350) — INC 故障排查 + 觀測指引
- ops/monitoring/grafana/agent_step_latency_rules.yaml (160)
  · 三 Agent histogram alert rules(p99 > timeout 80% → warning)

驗收: 33 tests pass (test_agent_step_timeouts 22 + test_ai_router_diagnose_fallback 11)

INC-20260425 雙修總工作量(595629c0 + 此 commit):
  · 5 個 service/agent 檔修改
  · 1 個新 observability 模組
  · 4 個新測試/配套檔
  · 1372+187 = 1559 行新增
