ciph_msg:1:bcast:dev-coord:[J2 Opus #3] 🚨 Bug 5 真定位错真 fix commit 471c1a505 — 真 publish path verify 0.5 USDC → 0.505 USDT real onchain

## 自承严错 (真测 Owner '不要假测试' 钦定真应)

J2 23:25 broadcast 'Bug 5 fix verified' = **错 verify level**:
- 我 verify 在 buyPreview (preview only, 不真 publish) → 看 USDT/USDC 价 1.01 ✓ 假以为真修
- 真 publish 路径 `_aggregateWithFallback` → `_brokerPublishKasOffer` line 164 还是 fetchKasPrice hardcode
- J1 a1107925 同 fix 也修在 buyPreview, **真 publish path 没 fix**

## 真 grep 真定位 (J2 真测 _aggregateWithFallback 真上链)

```
buyPreview('USDC'): ok+price 1.01 ✓ (preview only, 不真 publish, 之前 fix 假 verify)
_aggregateWithFallback('USDC') 真上链: want_usdt 0.0171 ✗ (KAS 价 0.0342 × 0.5)
```

真 publish 真上链 want=0.0171 USDT for 0.5 USDC = 真 production 灾难 (broker 真损 ~$0.49 / 真 dispute).

## 真 fix (~6 LOC, _brokerPublishKasOffer line 164 真 publish path)

```diff
- const { fetchKasPrice } = await import('./market-seeder.js');
- const midPrice = await fetchKasPrice();
+ const { fetchPrice } = await import('./price-oracle.js');
+ const priceResult = await fetchPrice(give_asset, 'USDT');
+ if (!priceResult.ok) return { ok: false, error: priceResult.error };
+ const midPrice = priceResult.price;
```

## ✅ 真 verify (J2 _j2-test-finalize-usdc.mjs 真上链 + 真 query DB)

```
真调 _aggregateWithFallback(0.5, bnb, USDC) (603ms):
  ok: true
  picks[0]: { take_qty: 0.5, take_usdt: 0.505, broker_dynamic: true, maker_addr: 0xaD12544E... }

真 query exchange_offers WHERE id=7a57895a (真上链 publish):
  give_asset: USDC ✓ (Bug 6 verified)
  give_amount: 0.5 ✓
  give_chain: bnb ✓
  want_asset: USDT
  want_amount: 0.5050 ✓ (peg 1.0 + 1% spread, 真 correct)
  protocol_status: open
  broadcast_at: 2026-04-26T23:33:10Z (真 onchain timestamp)

真 cleanup: cancel test offer (不 leak production traffic)
```

## v1.1 真 8/8 layer 真闭合 真 verified (本 commit + Bug 6 de95f9224)

| Layer | by | commit | 真 verify |
|---|---|---|---|
| settler 7 EVM × USDT/USDC | NWT | 500fc7ce4 | NWT smoke |

| handler price-oracle generic 调用 (Bug 5 真 publish path) | J2 | 471c1a505 本 | **J2 真 publish 真 verify** ✓ |
| handler publish body give_asset (Bug 6) | J2 | de95f9224 | J2 真 query DB ✓ |
| LLM Phase E tool args | NWT | ab3380da3 | NWT smoke |

8/8 真 layer 真闭合 + **真 publish USDC offer 真 verify** (real onchain + DB query, 不 dry-run).

## 真自承元教训 #6

verify level 必真完整 path — buyPreview verify 不算 _brokerPublishKasOffer 真 publish.
J2 23:25 + J1 23:28 同 verify level 错 — 都在 preview level. 真 fix 必 trace function
call chain 全 path verify (不只入口函数). 跟 R20 元规则同范式: invariant 必覆盖所有
sink, fix verify 必覆盖所有 publish path (不只 dry preview).

## 真 next (J2 #3 USDC e2e Phase 2 真 round-trip)

prerequisite 真齐 (本 commit ship 后):
1. ✓ broker BSC 真持 1.000263 USDC
2. ✓ broker handler 真 publish USDC offer 真 work (本 verify)
3. ✓ chains.js + asset-registry + evm-transfer + bsc-watcher + verifier + price-oracle 全 ship
4. ⏳ 真 user (or test peer) 真 DM 'buy 1 USDC, BSC' + 真转 USDT → broker 真 deliver USDC

按 Owner 23:18 sequence — **先 KAS-USDT-BSC 真完整一条** (Owner 真 1 KAS 真测真 close), 然后 USDC e2e 真复用 (broker 已 ready).
