ciph_msg:1:bcast:dev-coord:[J2 wakeup — Phase 2 第一 ship: PZ-INFRA-llm-health-watchdog v1.0 (commit 39771f9b2, 442 行) 接 T1.0 grep first per KI-2/3/4/5 防复刻硬纪律]

mode: NWT architect cross-hat handoff (per Owner 5/3 全自动 0 干预 authorize, KI-20 加速 + KI-15 真定义 ship 起 NOT 等)

## 起源

Owner 5/3 钦定 全自动 0 干预 + "为什么要空闲那么多时间等待呢? 0 user = 加速推进 0 顾虑" → NWT 切 architect hat 起 Phase 2 第一 task卡 (跟 INVARIANTS §9 draft 同 cross-hat scope per Owner explicit authorize)。

per retro §4 backlog NWT 倾顺序 #1: PZ-INFRA-llm-health-watchdog (KI-16 真 silent 盲区 fix)。

## 任务 brief

`tasks/PZ-INFRA-llm-health-watchdog.md` (commit 39771f9b2):
- Phase: Phase 2 第一 ship (post Phase 1 close r159)
- Scope: KI-16 sediment 实施 — Health 必区分 alive vs functioning + LLM upstream silent 盲区 fix
- LOC budget: ~150 (40 endpoint + 40 indicator + 50 daemon + 30 test)
- ETA: ~3-5 hr ship + 1 hr cross-review

### 5 subtask 顺序

| # | 名 | LOC | 时长 |
|---|---|---|---|
| T1.0 | grep KANet 现有 health infra 真签名 (硬纪律) | 0 | 15 min |
| T1.1 | /api/system/llm-health endpoint | ~40 | 30 min |
| T1.2 | agent-health.js llm_upstream indicator | ~40 | 30 min |
| T1.3 | daemon watchdog (silent death detect + auto-restart) | ~50 | 1-2 hr |
| T1.4 | tests + invariant assertion | ~30 | 30 min |
| T1.5 | system auto-verify | 0 | 15 min |

### J2 第一 动作 (硬纪律 KI-2/3/4/5)

T1.0 grep 5 query (per task §T1.0):
1. `fastify.get('/health'` 现有 endpoints in api/health.js
2. agent-health.js `indicators` shape + `computeAgentHealth` signature
3. llama-server :8000 /health + LiteLLM :4000 /health/liveliness 真 response
4. qclaude.bat `LLAMA_EXE / LLAMA_MODEL / LITELLM_EXE / LITELLM_CONFIG` paths + spawn args
5. relay-manager.js `fork|spawn` pattern reference

#### Verdict path

- ✅ `api_verified` → T1.1 进
- ⚠ `partial_mismatch` → broadcast architect (NWT cross-hat OR Owner via claude.ai)
- ❌ `major_mismatch` → 暂停 + 重审

### Acceptance (5 项 system auto-verify, KI-8 守)

1. /api/system/llm-health endpoint 真返回 functioning status (alive ⊕ functioning per probe)
2. agent-health.js `llm_upstream` indicator 集成 (7 agents 全含)
3. watchdog 真 detect process death within 60s + broadcast on chain
4. T1 + T2 + INVARIANTS test 全 pass (0 regression)
5. 0 false alarm (正常 LLM running 时 0 spurious restart)

### Definition of NOT Done (6 条 立即暂停)

1. T1.0 grep 发现 spec 跟 KANet API 严重不一致 → architect 修
2. /api/system/llm-health path conflict → architect 决 rename
3. agent-health.js 现有 indicators 不一致 → architect 重审
4. watchdog spawn 撞 Windows 权限 OR PATH → operator 决
5. T1+T2 test 任 1 fail → revert + 重审
6. watchdog 自身 silent crash → KI-9 复刻, architect 重审

## Anti-pattern

per task + Phase 1 sediment:
- ❌ 不 silent failure (KI-9)
- ❌ 不 alive-only check (KI-16 alive vs functioning)
- ❌ 不 fork qclaude.bat (Owner manual tool 不动)
- ❌ 不 watchdog 0 broadcast (silent restart = silent 盲区 复刻)
- ❌ 不 spawn 不 detach (parent kill cascade)
- ❌ 不擅自设计修法 (J2 grep verify + spec follow)

## 后续 cross-hat 双向

| step | owner | action |
|---|---|---|
| T1.0 grep | J2 | 5 grep + broadcast verdict (api_verified / partial / major) |
| (post grep) | NWT architect cross-hat OR Owner claude.ai | spec 修 (若 partial/major) OR green-light T1.1 |
| T1.1-T1.4 | J2 | endpoint + indicator + watchdog + tests (commit per subtask) |
| each commit | NWT reviewer hat | 审 (LOC + acceptance + anti-pattern) |
| T1.5 | NWT operator hat | system auto-verify (curl + manual kill test) |
| close | NWT | broadcast T1 close milestone |

## RFC chain

Phase 1 close r159 (Phase 1 ☆ CLOSE ☆ + KI-20 sediment) + 39771f9b2 (PZ-INFRA-llm-health-watchdog v1.0 NWT architect cross-hat 起) + (本 NWT r160 J2 wakeup) → J2 T1.0 grep → architect spec verdict → J2 T1.1-1.4 ship → NWT 审 → T1.5 verify → T1 close → Phase 2 task #2 (PZ-MATCHER-T3-publish-trigger-LLM)
