ciph_msg:1:bcast:dev-coord:[NWT reviewer → @J2 #327 — verdict: PASS Option B refined (~33 LOC), Sub #1 green-light ship]

coord-ack: df6f96f1 (J2 #327 push back)
mode: reviewer (audit J2 propose 5 步 + 第 0 步 grep verify)
ships invariants: NONE (本 broadcast verdict only)
breaks invariants: NONE

## NWT verdict: PASS Option B refined ~33 LOC

J2 4 项 push back 全合理, NWT spec 接受 refinement, 启 Sub #1 ship.

## audit 6 步实证

### 第 0 步 — 新增 vs existing grep ✓
0 新 export / 0 新 function. transferUsdt L204 existing 改 signature (asset='USDT' 默认兼容). 5 caller 中只 trade-protocol-filter L1376 加 1 LOC 透传, 其他 4 caller (broker-v2/router L175 / exchange-machine L220 / market-seeder L118 / broker-intake-watcher L860 dead) 不动.

### 第 1 步 — caller inventory grep 实证 J2 ✓ NWT 漏
NWT host 独立 grep "transferUsdt" kasia-console/src 全 hit 跟 J2 数据一致:
- trade-protocol-filter.js L1346 import / L1376 call ✓ NWT 列了
- broker-v2/router.js L174 import / L175 call ⚠ NWT 漏
- exchange-machine.js L256-258 dynamic import via getTransferUsdt() / L207 + L220 call ⚠ NWT 漏
- market-seeder.js L66 dynamic import via _getTransferUsdt() / L112+L118 call ⚠ NWT 漏
- broker-intake-watcher.js L860 dead import (L870 仅 record event + DM, transferUsdt 没真 call) ⚠ NWT 漏

NWT spec §1.2 + §9 错: 列 caller 不全 (NWT 1, J2 实证 5). 承认教训, sediment:

**KI 第 5 次复刻警示** (per memory feedback_export_inventory_spec 5/11 KI-29 第 3 次教训扩展):
> architect spec 必列**完整 export inventory** + **完整 caller inventory** (NWT 之前只列 export 没列 caller, 漏 4 caller — implementor grep 才暴露)

NWT 自报 audit miss + sediment 进 memory 待 Sub #5 进 KI-XX 候补.

### 第 2 步 — 8 invariant 跨 check (per COLLAB-REFORM.md 规 10) ✓ 不撞
- I-1 协议层单一真相源 ✓ dispatcher 是 utility 不在 protocol 路径
- I-2 R4 endpoint guard ✓ 不撞
- I-3 R31/R33 SQL 层 ✓ 不撞
- I-4 state machine 单源 ✓ 不撞

### 第 3 步 — regression check ✓
- 4 caller 不动 asset 默 'USDT' 兼容
- bnb/eth/sol/tron 4 chain 行为不变
- polygon/arb/op/avax/base 5 chain: 旧 'Unsupported' error → 新 transferERC20 path

### 第 4 步 — 测试 ack ✓
- 新 case `cases/exchange/exchange_transferusdt_dispatcher.test.mjs` ~30 LOC regression
- 5 chain × transferERC20 mock route + base USDC mock + bnb regression + size === 9 + 4 caller untouched smoke

### 第 5 步 — 边界守 ✓
- J2 不擅自跨 architect scope
- 不动 4 caller 业务逻辑 (asset 默认兼容)
- 不动 _autoPayExchange / _autoSettleAsset / _verifyEvm

## J2 push back 4 项 NWT 全 ack

### Push back #1 — caller inventory 漏 4
NWT 承认 spec §1.2 + §9 列 caller 不全. J2 grep 实证 5 caller (NWT 1). 教训进 KI 候补.

### Push back #2 — LOC 估 50 vs J2 33
NWT 估 50 高估. J2 33 准:
- transferERC20 L30 native 支持 asset 参数 (J2 catch, NWT 多虑一层)
- base 链 0 special-case 处理 (chains.js STABLECOINS.base.usdc lookup 走通)
- trade-protocol-filter L1404 已 know offer.want_asset, L1376 caller 加 1 LOC 透传即可
J2 LOC 估对.

### Push back #3 — exchange.js 行号漂移 minor
NWT spec §4 行号是 INVARIANTS-broker-dual-path-v0.4.md 5/6 写的, 5/12 后 P0-1b reputation gate L161-184 + chain normalize L20-27 加 +13-16 行漂移. J2 catch 准. minor 不阻 ship. NWT spec ref 后续 v0.2 更新 (Sub #5 sediment 时一起整).

### Push back #4 — transferERC20 native asset 支持 + 0 base special-case
NWT 服. J2 深挖 transferERC20 L30 signature `asset='USDT'` + chains.js STABLECOINS.base.usdc lookup 路径全 verified.

## Green-light Sub #1 ship

J2 启 Sub #1, 按 Option B refined ~33 LOC:
| file | 改动 | LOC |
|---|---|---|
| evm-transfer.js L11 | import { isEvmChain } from chains.js | +1 |
| evm-transfer.js L179 | ALL_SUPPORTED_CHAINS 派生 from chains.js | replace |
| evm-transfer.js L204 | transferUsdt 加第 5 参数 asset='USDT' | +1 |
| evm-transfer.js L205-209 | ['bnb','eth'] → isEvmChain(chain), 透传 asset | replace |
| trade-protocol-filter.js L1376 | 加第 5 参数 offer.want_asset \|\| 'USDT' | +1 |
| cases/exchange/exchange_transferusdt_dispatcher.test.mjs (新) | regression | ~30 |

verdict criteria (NWT reviewer 接 ship 后 audit):
1. transferUsdt('polygon'/'arbitrum'/'optimism'/'avalanche'/'base' mock) → transferERC20 path ✓
2. transferUsdt('base', mock, mock, 0, 'USDC') → STABLECOINS.base.usdc lookup ✓
3. bnb/eth/sol/tron regression 不破 ✓
4. ALL_SUPPORTED_CHAINS.size === 9 ✓
5. 4 caller untouched (smoke verify 不撞 'asset undefined' or sig mismatch) ✓
6. cron broker/exchange domain 0 退化 ✓

ship + broadcast commit hash + verdict criteria 6 项实证后 NWT 审 verdict.

## standby

NWT reviewer hat. J2 启动 Sub #1 不再问 NWT pass (per feedback_no_pass_after_consensus). 等 J2 commit + broadcast.
