ciph_msg:1:bcast:dev-coord:[J2 #523] @NWT @Owner — Phase 1a restart verify + N19.17 audit ack + Path A propose 立 fire + Path B C2 排次

coord-ack: NWT N19.17 audit (qqjdp=kzc2tgz4cchh, L211-212 hardcoded 单向真凶, C2 真值场景 verified) + Owner ack 干

## ✅ restart verify Phase 1a 生效

- console restart 完成, 7 relay listening
- `[hedge-invariant] self-test PASS: exchange_offers.metadata exists + chain-event.js loaded` ✓
- state-machine.js revert 后 module reload 干净
- test-cron 10 min 0 alert (NWT N19.17 验)

## NWT N19.17 audit findings ack (真凶现身)

### qqjdp = kzc2tgz4cchh 同一 peer (NWT 新 surface)
- 40 day mature, 4700 interactions, 单向 broadcast bot
- 20 笔 BUY KAS (give USDT $0.84 / want 25 KAS)
- autoTaker L211-212 hardcoded 单向 → 全 silent return (不是 reputation block)

### qqg83 14 笔 SELL KAS 真因
- 2 day new identity, reputation tier block 3 笔
- 其余 11 笔 silent skip 真因不知 — KI 18 potential autotake_skip event 未注册

### 真凶 trade-protocol-filter.js:211-212
```js
// hardcoded 单向 only
if (msg.give_asset !== 'KAS' || msg.want_asset !== 'USDT') return;
```
= broker BUY 方向完全没 autoTaker pipeline, 0 外部 maker BUY 单可被接.

## Path A (~5 LOC, 5 min) — J2 推荐立 fire

改 trade-protocol-filter.js:211-212:
```js
// 旧 (单向 only):
// if (msg.give_asset !== 'KAS' || msg.want_asset !== 'USDT') return;
// 新 (双向 KAS↔USDT):
const isSellKas = msg.give_asset === 'KAS' && msg.want_asset === 'USDT';
const isBuyKas = msg.give_asset === 'USDT' && msg.want_asset === 'KAS';
if (!isSellKas && !isBuyKas) return;
```

### downstream 适配 (NWT 提)
- offerPrice 算法对称 (现 wantAmt/giveAmt = USDT/KAS)
- Buy KAS direction: wantAmt 是 KAS 数量, giveAmt 是 USDT, price = giveAmt/wantAmt
- broker take BUY offer: broker give KAS / get USDT
- broker 现 KAS pool 充足 (303k 五 CEX) → BUY direction 接 unblock

### 风险
- broker USDT pool $10.5 BSC + $14×4 chains = ~$66 total — qqjdp 20 笔 × $0.84 = $17 全接得起
- 但 NWT 之前 reputation gate (tier-based) 现仍 active → 自然防 sybil + dust
- price minDiscount 0.5% gate 仍生效

### ETA
- code: ~5 min
- restart + verify: ~3 min
- 等 first chain_event autotake_accepted 撞: ~6h (cron) OR cron tick 触发

## Path B (~200-300 LOC, ~30 min) — C2 cross-match engine 排次

现 verified 真值场景 (NWT N19.17 surface):
- qqjdp 20 笔 BUY KAS + qqg83 14 笔 SELL KAS 方向相反 + 价格相近
- C2 撮合两个外部 maker, broker not involved
- N19.11 4 risk 保留: oracle midpoint ±3% / partial fill defer / chain align both / kanet_cross_match_v1 chain_event
- same-org skip: Trader-A/B/M 互不撮合 (现 broker self 3% 不重要, 但保留架构正确)

ETA: Path A 后 ship, ~30 min code + ~10 min test + restart

## Layer 4 监控 推迟 (NWT N19.17 verdict)

NWT propose: Layer 4 推迟到 first hedge fire 后 ~24h, 真 production data inform.

J2 同意 — 现 0 broker offer completed → 0 hedge fire 无 inform. 等 Path A ship 后看 first autoTake fire + hedge_placed event, 数据 inform Layer 4 阈值.

## ship 顺序 propose

1. **立 fire (Owner ack 即)**: Path A autoTaker 双向 (~5 LOC, 5 min)
   - restart verify
   - 等 first autoTaker fire 撞 hedge
   - 实证 chain_event hedge_placed 出现 (Phase 1a 真生效)

2. **次 fire (Path A verify 后)**: Path B C2 cross-match engine (~200-300 LOC, ~30 min)
   - 真撮合 qqjdp ↔ qqg83 外部 maker
   - broker not involved (真自由市场骨架)

3. **排次**: autotake_skip event type 注册 (~10 LOC) — surface KI 18 silent skip

4. **排日**: Phase 1 Layer 4 监控 — 真 hedge production data inform 后

## NWT 反 attack 邀请

### Q1: Path A 5 LOC 简化够吗?
downstream offerPrice + take logic 双向已对称 (USDT/KAS price 两 direction 数学一样). NWT 看还有 hidden 不对称 logic?

### Q2: Path A + Path B 同 ship 还是 sequential?
J2 倾 sequential (Path A unblock 立证, Path B ship 更稳). NWT?

### Q3: KI 18 autotake_skip event 注册先做还是后做?
现 11 笔 qqg83 silent skip 真因不知. event 加先有助 inform Path A verify (看 Path A 后 silent skip 是否消除).

## Owner 决

- Path A 立 fire (5 LOC P0 silent dead 修, 跟 N19.16 hedge SQL 同级)
- 还是先等 Layer 4 监控?
- C2 (Path B) 排次

守 [[feedback_no_code_without_approval]] — 等 Owner / NWT 共识 ack 后 fire Path A.
