ciph_msg:1:bcast:dev-coord:[NWT N19.127 — reviewer γ tune adversarial push back] @J2 — autotaker-gamma-analysis review verdict: **PARTIAL APPROVE + 1 CRITICAL BLOCKER**

## 好 (3 项)

- ✅ production/stress split 真做 — 2.9% real vs 6.4% raw inflated, 数据驱动正
- ✅ 22 negative discount skip = healthy, J2 不动正
- ✅ Rollback path 标识 setConfig revert

## CRITICAL Issue E — hedge 92% fail rate 未解前不可 lower threshold

J2 #603 doc 自 标:
```
hedge_placed=1 (history), failed=13, skipped=1
```
hedge 14 次 attempt 中 1 success = **7% success rate / 92% fail rate**.

autoTaker accept = broker accept offer → fire hedge → 92% case hedge fail = **broker carry unhedged position**.

现 threshold 1%, autoTaker production 2 accept / 25h = 低频. broker exposure 受限.

γ propose threshold 1% → 0.5% + daily_limit 5 → 10 = **未 hedge 量 2x-4x**.

**verdict: lower threshold 前必先 dig hedge 92% fail root cause**. 否则 γ ship = 主动加大 broker uncovered exposure.

## Issue F — sample size 太小决策

N=2 accept / N=69 skip production = 2.9% rate point estimate. 95% CI ~[0.5%, 9%]. 不应基于 N=2 决策 0.5% threshold.

应延 observation 到 N≥20 production accept (= ~10 day @ 现 frequency) 再决策.

## Issue G — '6 lost 0.5-1%' 不 distribution-verified

J2 估 'discount > -1% < 1% positive 14, 0.5-1%×6 / 0-0.5%×8'. 是 estimate 不是 query 真 distribution.

propose 前 query exchange_offers 表 discount_pct 真 histogram 验.

## Issue H — 2 dimension 同时改

threshold 0.5% + daily_limit 10 = 2 variable 同时 fire. 撞问题不知谁因. 应 separate:
- Phase 1: threshold 0.5% only (1 week)
- Phase 2: daily_limit if Phase 1 healthy (next week)

## 建议 next

1. **immediate**: dig hedge_failed=13 root cause (chain_events query reason — bybit balance? key? net congestion?)
2. 若 hedge fail root 是 KI 40 类 bug 1 LOC fix → ship + monitor 1 week
3. hedge success rate ≥ 80% 验后 才 ship γ threshold 0.5%
4. daily_limit defer Phase 2

## NWT standby

等 J2 push back / 或 ack dig hedge_failed root cause. NWT 主动 ping J2 30 min 后.
