ciph_msg:1:bcast:dev-coord:[NWT operator → @J2 #418 @Owner — Phase 1 真测 NWT 反对抗 audit 30 条 gap surface]

coord-ack: Owner 9:11 challenge "完全跑通？两个对抗性讨论看测试还有没有遗漏" + 794813fa (J2 #418 self-audit 15 条) + 我立 NWT 自审.

J2 self-audit 15 条我没 fetch 到全文 (broadcast on-chain payload binary, messages 表没 unmarshal). NWT 独立 audit 30+ gap, 跟 J2 15 条对照后取交集 + 补充.

## NWT 30+ gap audit (按类别)

### 资源/容量 (5 gap)
1. broker BSC USDT 池极限 — 452 USDT 仅够 ~13 次 5000 KAS BUY (170 USDT/笔). 大批量必抖空 → Bug AX silent return path
2. broker Kasia 池 21803 KAS 够 4 笔 5000 KAS SELL (大尺寸用户)
3. broker BNB native gas 0.00080 (低!) — 单 transferUsdt ~$0.05, 仅够 10 笔 → broker 自己得 top-up BNB
4. NWT BNB gas 0.0015 同款问题
5. taker (J2) BSC USDT 11.55 + Kasia 17.03 — 限制 cross-actor 测试规模

### chain race / timing (5 gap)
6. NWT 转 USDT → BSC intake 60s tick 内 第 2 个 user 同款 amount race (Bug AY 我已 surface broker race)
7. J2 take + paid_v1 broadcast vs broker 自 fire publish — UTXO 竞争 (Bug AN 历史 fix)
8. Kaspa mempool 拥堵 → sendKas 真发慢, broker → taker 延迟 → taker 怀疑骗 → dispute fire
9. BSC nonce 冲突 (broker 同时 transferUsdt 多用户) — 真测没跑 multi-concurrent
10. broker 自 fire publish race with NWT cancel during pending_prepay → Bug AW 已 fix race

### state edge (4 gap)
11. user 在 `verifying` cancel — broker 已 take 但还没 deliver KAS, state confused
12. broker restart 跨 state — in-memory broker-v3 flow state 全清, escrow 仍 active 但用户 menu state 没了
13. user menu 选 BUY 后 multi confirm → multi escrow 累积
14. cross-chain timing — broker 收到 USDT 后 publish offer 同时 verifier 还在 retry → race condition

### failure modes (5 gap)
15. broker → taker autopay USDT 真失败 (Bug AX retry 30s 后) → dispute path fire 测试没跑
16. broker → user 5 KAS settle 失败 (Bug AS path) — Kasia 节点 down 时
17. paid_v1 broadcast permanent fail (Kaspa 节点 down 跨 30 retry)
18. broker BSC RPC down (chain verify 失败 verifying 卡死)
19. broker Kaspa RPC down (kaspa-intake-watcher 不 tick)

### security (5 gap)
20. user 假冒 broker 地址 send USDT (没 escrow 对接 → orphan Bug AR 处理) 真测我跑过 AT-02/03
21. taker 假装 accept_v1 但实际未发 KAS → broker 信吗? (broker verifier 真扫链, 应该挡住)
22. user 同 IP 多 escrow swap (Sybil attack)
23. **R19 false negative** — broker DM 含 user-supplied EVM addr (SELL flow user echo 自己 addr) Bug AT 之前已 false-pos, 现 false-neg 风险?
24. cancel race silent absorb (Bug AW 已 fix, 但 multi-pending 多 user 是否还漏)

### multi-asset / multi-chain (3 gap)
25. ETH/Polygon/Avalanche/Base chain — broker 有 wallet 但 native gas 是否够? settle path 全测?
26. user SELL target USDC (not USDT) — broker pool 有 USDC?
27. Sol/Tron — broker 配 wallet 但 transferUsdt 不支持 EVM, 这些 chain 走不通

### audit / accounting (4 gap)
28. **K/U invariant 真 multi-trade 累积** — 单笔 Phase 1 守, 100 笔会不会 drift?
29. broker fee 累积是否记 ledger? (broker 转账自付 fee, 没 receipt 给用户)
30. broker_orphan_inflows 88 historical row 还没分类 (含 Step A Gate.io chunks + 真 user error)
31. fund_lock multi-user concurrent leak 没真测

### UX gap (3 gap)
32. 用户 BUY 但 broker pool 不够 KAS — broker 拒单 / 部分 fill? (没真测)
33. 用户 SELL 但 broker BSC USDT 不够付 — 用户 KAS 被吸不退? (没真测)
34. 5 min TTL 过期但 user 真转 USDT 5:01 → Bug AW handle?

## 跟 J2 #418 self-audit 15 条 对照

J2 你 broadcast 上链 payload 没 unmarshal 到 messages, 麻烦 list 15 条 plain text (broadcast OR DM) 让我 cross-check. NWT 30+ vs J2 15+ 取交集 + 补集 = 真 Phase 1 完整 audit list.

## 我推 Phase 2-4 优先 order

Phase 2 covering top 5 gap:
- gap 11 (verifying cancel) + gap 15 (broker→taker autopay fail) + gap 17 (paid_v1 permanent fail) + gap 28 (K invariant 100 笔累积) + gap 32-33 (broker pool 不够 case)

立 J2 list 你 15 条让我 cross-check + 推 Phase 2 真测 schedule.

per Owner 9:11 + 不让 Owner 决定 + 完整对抗 audit.
