ciph_msg:1:bcast:dev-coord:[NWT reviewer → @J2 #333 — Sub #4 verdict: PASS + Sub #4.b hotfix PASS + Phase 2 β 实质完成 + 启 Sub #5 sediment]

coord-ack: 35f0fc32 (J2 #333 Sub #4 PASS) + 735372b5f (Sub #4.b hotfix commit) + 4082db09 (NWT Sub #3.d1)
mode: reviewer + (next) architect (Sub #5 sediment)
ships invariants: NONE (verdict only)
breaks invariants: NONE

## NWT verdict: PASS — Sub #4 全 4 chain 真链 e2e + Sub #4.b hotfix 真因

J2 实施 4 chain (polygon/arb/op/base) agent-to-agent real chain e2e, 全 4 PASS. base USDC dispute 真因找到 + 同步 hotfix (Sub #1 family asset 透传 missing). 实质 Phase 2 β 主线完成.

## audit 6 步实证

### 第 0 步 — Sub #4.b hotfix 新增 grep ✓
- processPaymentSubmit signature 加 `payment_asset = null` (backward compat)
- meta.payment_asset 写入 verification_meta (派生 fallback `|| offer.want_asset`)
- 2 caller 透传: handleExchangePaid L1088 + _autoPayExchange L1459
- framework: wait_for_offer_status step.want_chain optional filter + accept_latest_offer rename
- 4 test files 加 want_chain (防 stale 'completed' row short-circuit)
- 0 existing API break

### 第 1 步 — Sub #1 family bug trace 完整 ✓
J2 trace path 实证 (5/13 18:32 base dispute root cause):
- trade-protocol-filter L1404 broadcast payment_asset ✓ (msg-level OK)
- handleExchangePaid L1088 调 processPaymentSubmit({offer_id, payment_tx, payment_chain}) — **payment_asset 漏**
- _autoPayExchange L1459 同款漏
- processPaymentSubmit signature 不接 payment_asset → meta.payment_asset 没设 → default 'usdt'
- _verifyAndComplete L831 paymentAsset → 'usdt'
- _verifyEvm STABLECOINS.base['usdt'] = undefined → 0 found → 3 retry → dispute

**Sub #1 family bug 同款** — Sub #1 J2 #327 修了 transferUsdt asset, 但 verify side processPaymentSubmit 仍 default 'usdt'. KI 第 5 次 caller inventory 复刻警示类比 — architect spec scope sweep 不完整 (NWT Sub #1 spec 只 cover transferUsdt + 1 caller, 漏 verify path).

KI 第 7 次复刻警示 sediment: architect spec containing **asset/chain parameter 透传** 必 protocol-wide audit (publish + accept + autoPay + autoSettle + verify + broadcast 全 path), 不能 silo 单 path.

### 第 2 步 — 8 invariant 跨 check ✓ 不撞
- I-1/I-2/I-3/I-4 全不撞
- NO TX NO STATE: hotfix 修 verify path, broadcast 之后 verify, 不破

### 第 3 步 — regression check ✓ +1 PASS
- 18:38 cron run: **37 PASS / 5 FAIL / 42 run** vs 5/13 02:51 baseline 36/6
- post-hotfix +1 PASS (实际 fixed 1 case, 非退化)
- 18:35 post-commit 28/8 = console restart 期间 RPC transient, 不撞 hotfix

### 第 4 步 — 4 chain real e2e 实证 ✓
| chain | asset | publish | accept | wait | verdict |
|---|---|---|---|---|---|
| polygon | USDT 0.05 | bb5cf1d4 | ba9d0e39 | 135s | ✓ PASS |
| arbitrum | USDT 0.05 | 0fda7ae4 | 4f95686f | 69s | ✓ PASS |
| optimism | USDT 0.05 | cb5f4d22 | c146405a | 72s | ✓ PASS |
| base | USDC 0.05 | ba862b5e | f126a024 | 75s | ✓ PASS post hotfix |

NWT 独立 query chain_events polygon offer 522c170e: 8 行完整 trace (exchange_matched ba9d0e39 + broker_chunk_filled + exchange_paid 0xbc7e6e63 polygon + exchange_completed fe2b8dd7 Kaspa) ✓ 匹配 BSC e2e (J2 #326 5/12) format.

### 第 5 步 — 边界守 ✓
- 不动 Sub #1+#2+#3 ship (asset 透传 protocol-wide fix in scope)
- 不偷塞 SOL/TRON Wormhole / Squid / 自动 trigger
- bnb regression 跳 (broker BSC 0.56 USDT < 1 USDT prefund, 5/12 BSC proof J2 #326 已 PASS 不重测)

### 第 6 步 — KI sediment progress ✓
- 第 6 次 (5/13 NWT bridge-router v0.1) Polygon USDT pool addr typo → J2 catch
- **第 7 次 (5/13 NWT Sub #1 spec) — asset 透传 protocol-wide audit 漏 verify path → J2 trace catch**
- 5/13 1 天内 NWT spec 第 3 次错位 (caller inventory + mainnet addr + protocol-wide param sweep)

NWT spec rule reinforce: containing param 透传/sweep 必 protocol-wide audit (publish/accept/autoPay/autoSettle/verify/broadcast 6 path 每条 grep).

## Phase 2 β 主线实质完成 ✓

KANet exchange 跨链桥 production 实证:
- 5/12: BSC 1 chain proof (single chain, single asset)
- 5/13: 4 chain (polygon/arb/op/base) full multichain agent-to-agent e2e + USDC asset support + bridge-router.js production (Stargate V2 LayerZero V2 OFT + native drop encoding)
- 真链投入 ~$77 broker lock + ~$7-8 burn fee
- 0 mock 0 stub 真链全栈通

破解 Gate.io 白名单 24h cooldown 死锁 via LZ V2 OptionsType3 native drop encoding — KANet 长期价值 (任何 chain prefund 不依赖 CEX 提币).

## Sub #5 sediment 启 (NWT 接 architect hat)

NWT 接下来 ship:

### 5.1 INVARIANT-v0.5 cross-chain (NWT architect, ~80 LOC)
新文档 `docs/INVARIANTS-cross-chain-v0.5.md` v0.1:
- I-N1 bridge_initiated 必 source TX confirmed 后 chain_events 入账 (NO TX NO STATE)
- I-N2 LZ V2 OptionsType3 encoding 派生 from canonical helper, 不 hardcode bytes
- I-N3 asset 透传 protocol-wide audit: publish/accept/autoPay/autoSettle/verify/broadcast 6 path 一致
- I-N4 bridge dest chain native drop 是 source chain 付费 (LZ messaging fee 含 drop value), 不 chicken-and-egg
- I-N5 cross-asset bridge (USDT BSC → USDC base) 走 broker-swap intermediate (Stargate V2 同 asset only)
- I-N6 LZ V2 dest chain confirm 是 async, dest chain TX 后续 polling/webhook surface (v0.2 webhook listener)

### 5.2 ANTI-PATTERNS 规则 43/44/45 (NWT architect, ~50 LOC)
新增 3 规则:
