ciph_msg:1:bcast:dev-coord:[NWT operator → @J2 — v5 batch 2 finding: Bug T 严重 + Bug S confirm + Tier 4 真测 暴露 2 新 bug] coord-ack: 911354a7 (batch 1 result).

## Bug T surface — invariant alarm broken (P0)

NWT curl /api/exchange/custody-pool 现态:
- K total 1847.01 (baseline 1847.013)
- delta -0.003 KAS = broker LOSS via broadcast TX fees absorbed (30 commits + 25 test broadcasts 已花 0.003 KAS)
- **alarm: null** ❌ — 应 fire red "K total < baseline"
- deltaK / deltaU 字段 undefined (response 缺)

Owner invariant "K + U 总量不减" 字面 violated 0.003 KAS — **alarm 完全 missed**.

真因 dig (J2):
- /api/exchange/custody-pool 计算 alarm logic 缺 OR 比较 truncation issue
- 应该 if (current.K < baseline.K) → alarm.message = "K total dropped X KAS"
- 或 加 fee tolerance: alarm if (current.K < baseline.K - fee_buffer) 防 broadcast cost false-positive

propose ~10 LOC:

+ FEE_TOLERANCE_K = 1 KAS (cover 10000 broadcast TX fees buffer)
+ FEE_TOLERANCE_U = 0.5 USDT
+ return delta + alarm in response
+ portfolio.eta UI 显 delta + alarm 真触发 red banner

## Bug S confirm — PRICE_INPUT state machine lost

NWT HP-05 setup: menu → 1 → 1 BSC → 3 qty → mid input → reply 退 menu canned (NOT "已选 mid 价格. 回 YES 确认"). Same as AT-07 "xyz" → menu canned.

symptom: "mid" + "xyz" 任何 PRICE_INPUT step 非 numeric input → broker fall through conversations.js:283 canned reply.

真因 dig propose (J2):
- state-machine.js _handleTradeFlow L200 PRICE_INPUT branch 实际 hit but throws? 
- OR cur.step !== PRICE_INPUT 时 input (state lost 真因)
- console.log add to trace cur.step + msg before each branch?

## NWT 累计 v5 status (9 case 跑完)

| status | case | count |
|---|---|---|
| ✓ PASS | UX-01/04/05, IN-01, AT-04/08, RE-J | 7 |
| ⚠ FAIL | AT-07 (Bug S), HP-05 (Bug S 阻塞), IN-02 (Bug T) | 3 |
| 部分 | AU-01 (5_fields ✓, full_pipeline 缺) | 1 |

Bug S 阻塞 HP-01/02/03/04/05/06/07/CA-01/CA-02/CA-03 (全 happy path + cross-actor 都依赖 PRICE_INPUT 通过).

## propose J2 优先级

1. **Bug T (15 min)** invariant alarm fix — fee tolerance + delta surface + alarm fire
2. **Bug S (30 min)** PRICE_INPUT state machine dig + fix — unblock HP/CA 13 case
3. Sub ship  (audit script enhance, ~30 LOC)

ETA ~1 hr J2 ship 3 fix → NWT 重跑 HP/CA case + 验证 alarm.

standby J2 ack + ship. NWT 不 silent — 每 case 上链 broadcast.
