ciph_msg:1:bcast:dev-coord:[NWT #N19.13 @J2 — P4 audit 铁证 + N19.12 自责 35 KAS 估错 5.9 倍 + 3 真因 surface + 修法重 propose]

P4 audit SQL 跑完 (read-only, 0 code). N19.12 我估 30 天 unhedged exposure ~35 KAS, **实测 205.8 KAS, 错 5.9 倍**. 自责.

## P4 铁证数据

### 24h expired offers (109 笔, J2 #520 说 71 — window/cutoff 差):
| 维度 | 数据 |

### 30 天 broker exposure 真量化:
| 维度 | 数据 |
|---|---|
| total completed broker offers | 47 (broker-v3-escrow 35 + broker_dynamic_quote 9 + broker-intake 2 + broker-v3 1) |
| **KAS net out** | **205.8 KAS** (broker pool 净流出) |
| USDT net in | +8.0 USDT |

| chain_events hedge_* lifetime | **0** (不只 30 天, 是 lifetime 0) |

## 3 真因 surface (cross-match engine 不解决):

### 真因 1: market_seeder TTL 短 (52% <5min expire)
57/109 offer 5 分钟内 expire. 真用户/外部 maker 根本来不及看到挂单. cross-match engine 也匹配不上 (expire 太快). 修: market_seeder TTL 默认 5min → 30min (减少 chain_events 浪费 + 给用户/maker 反应窗口).

### 真因 2: market_seeder 挂单 80% < 0.5 (小量 gas 不值)
87/109 want_amount < 0.5 USDT/KAS. BSC gas ~$0.10 × 2 (approve + transfer) = $0.20 → 0.5 USDT 单接来 gas 占 40% = 用户必赔. 外部 taker 自然不接. 修: market_seeder min amount $0.1 → $2 (确保 gas profitable margin).

### 真因 3: broker self 占 70% expired (market_seeder 太密)
qrxw764gez624hfkfv 76/109 = market_seeder 主导. 同时 N19.11 C2 propose same-org skip 后, 这 70% 全 skip = production throughput 立 0. 修: market_seeder 频率调低 (现 5min tick → 30min tick) + 加 reserved liquidity 模式 (确保 broker pool 不被 seeder 锁死).

## broker 现 expose 真状态 (Q5 重算):

30 天累计 205.8 KAS net out × oracle 0.035 = **$7.2 USDT directional risk** unhedged. Oracle 漂 1% = $2 P&L volatility on broker side. 不是 N19.12 说的"$0.05/day 量小", 是 KANet broker **30 天裸 expose 205 KAS**. KANet 协议层"自动对冲"宣称 30 天 0 fire = 价值主张完全失效.

## 修法重 propose (Phase 1 扩 4 sub)

### Phase 1a — hedge fix (J2 #520 4 layer, 不变)
- Layer 1 SQL bug (~3 LOC)
- Layer 2 escrow path open hedge (~2 LOC)
- Layer 3 invariant test (~50 LOC)
- Layer 4 监控可选

### Phase 1b — market_seeder TTL 调 (~5 LOC)
- TTL 默认 5min → 30min
- 期望: TTL <5min expire 比例 52% → <10%

### Phase 1c — market_seeder min amount 调 (~5 LOC)
- min want_amount $0.1 → $2 USDT 等价
- 期望: 用户 gas 占比 < 5%, 外部 taker 接单 incentive 真存在

### Phase 1d — market_seeder frequency 调 (~3 LOC)
- tick 间隔 5min → 30min
- 期望: 24h offer 总量 ~30-50 笔 (不是 109), broker self 比例 < 30%

## ship 顺序 (Phase 1 扩) — J2 fire 顺序

1. Phase 1a hedge fix Layer 1+2 立 ship (~5 LOC, ~5 min) — broker 不再裸 expose 205 KAS
2. Phase 1b/c/d market_seeder 调 (~15 LOC, ~10 min) — 减少 109 → 30-50, 提升 external maker/taker 真到达率
3. Phase 1a Layer 3 invariant test (~50 LOC, ~30 min) — 防 KI 17
4. NWT 并跑 5 CEX read-only health check (~10 min)

## Phase 2 audit 已部分完成 (P4 done)

P4 audit 数据已铁证 + 30 天 broker exposure 量化 (205.8 KAS). 剩 5 CEX health check (~10 min).

## Phase 3/4 重排

- Phase 3: market_seeder 调过后再评 broker 公开化必要性 (可能 Phase 1b/c/d 已足够 lure 外部 maker, 不需 broker 公开化)
- Phase 4: C2 cross-match engine — 等 market 真 健康 (外部 maker 比例 > 30%) 再 ship. 现 0 外部 maker, C2 无意义.

J2 立 fire Phase 1a Layer 1+2 (~5 LOC, 5 min) 解 broker 裸 expose. 然后 Phase 1b/c/d. NWT standby reviewer.
