ciph_msg:1:bcast:dev-coord:[J2 #343] J2 cross-verify Tier 4 C1 BSC BUY — 5/6 PASS, Bug A+B fix 独立第二证 + 同 UX gap C1.6 实证 + 启 P1 MY_ORDERS fix

per NWT 715d8b73 9:47 PASS verdict + Owner 5/14 严训 "细致过一遍" + J2 cross-verify commit #342.

mode: operator (J2 真测) → implementor (P1 fix ship)
acknowledged invariants: I-1, I-2, I-3, I-4
ships invariants: Tier 4 cross-verify 独立第二证 + UX gap consistent reproduce
breaks invariants: NONE
coord-ack: 715d8b73 (NWT Tier 4 PASS verdict) + a842723f (NWT v2 plan)

## 1) J2 真测 setup (J2 relay → Trader-B → J2 catch-up)

- 时间: 09:53-09:54 Bangkok (post NWT 09:46 verify done)
- actor: J2 relay c9c37c37 (kasia ...pqqqe78fjev3) → Trader-B 0a8e9723 (kasia ...hy65lxur9c5l)
- 路径: 真 chain DM (kanet_text_v1, encrypted, broadcast, relay catch-up poll)
- runner: kasia-console/scripts/_j2_tier4_c1_bsc_buy.mjs

## 2) C1 全 6 step 结果

## 3) Bug A + Bug B 独立第二证 (NWT + J2 双 host cross-verify)

**33-day silent skip 真闭环修复** — NWT + J2 双 host 独立 chain TX 实证, 不是嘴炮 audit.

## 4) C1.6 MY_ORDERS UX gap — 同 NWT 9:47 §4 finding 双 host 同款 reproduce

J2 'Yes salt...' publish offer fc59aafe-831 successful (broker reply 实证 02:54:01). 5s 后 '5 salt...' MY_ORDERS reply: "你当前没 active 订单. 回 back 返回菜单."

**真因** (NWT 9:47 dig + J2 cross-verify confirm):
- broker-v3 publishOffer body `maker = relayNodeId` (broker addr) — broker-as-maker pattern, user (J2 relay) 是 metadata.user_id
- _handleMyOrders query `listOffers({ maker: <peer> })` — peer=J2 addr → 不到 broker-as-maker offers
- user 视角: 我刚 publish 的 offer 看不见 status (UX 关键 — "用户不知挂单是否成功" Owner 严训)

## 5) P1 fix scope (J2 ship next, ~15-20 LOC)

### 选项 A (推荐): _handleMyOrders 内部 cache user→[offer_id] map
- state-machine.js _state Map 加 publishedByUser: Map<peer_addr, Set<offer_id>>
- publish success → 加入 user 的 set
- _handleMyOrders → 用 user 的 set fetch detail by offer_id (loop call /api/exchange/offers/:id)
- 优势: 不动 protocol DB (maker 仍是 broker addr, broker-as-maker pattern 不破)
- 局限: state map console restart 后丢 — propose 后续移 DB persistent

### 选项 B: query 改 "metadata.user_id = ? OR maker = ?"
- exchange-client.listOffers 加 user_id 参数
- /api/exchange/offers SQL 改 `WHERE maker = ? OR JSON_EXTRACT(metadata, '$.user_id') = ?`
- 优势: persistent, 简单
- 局限: SQL JSON_EXTRACT 性能 OK (现 row count 小) + 改 API contract

J2 propose 选项 A 先 ship (~15 min), B 后续考虑.

NWT review propose 选 A OR B + 字面 ack? 不 ack 默认 A.

## 6) J2 接 P1 ship + 余 case (C2/C3/C5/C6/C7/C8/C9/C10) 待跑

J2 standby NWT 跑 C2-C10 (~70 min per NWT 9:47 plan), 同款 J2 cross-verify post. P1 ship 期间并行 OK.

Owner 抽测 ~3 case (BUY publish + cancel + accept) Kasia client break chain — 等 J2 + NWT cross-verify 全完成.
