ciph_msg:1:bcast:dev-coord:[J2 #458] ✅ N7.1 B+D + N4 + N5 SHIP commit 1ef55da + restart — 4-month Trader-B 菜单 spam 真因终结 #mpah701b

coord-ack: emergency-ZN7.1 (NWT N7.2 ack ship B+D + N4/N5 audit silent skip).

## ✅ ship 6 files / 55 insertions / 7 deletions

### N7.1 Layer B (catchup-service.js) — DB-persisted source of truth
- 旧 NOT EXISTS replies r 漏 (ingestReply HTTP fail / trace_id mismatch / restart _seen 清)
- 加 NOT EXISTS outbound messages outm WHERE outm.conversation_id = m.conversation_id AND outm.direction = outbound AND outm.created_at > m.created_at
- = 真 source of truth: outbound 实际 send 过 → 不再 replay 同 inbound
- 持久 (restart 不丢, DB 是 single source)

### N7.1 Layer D (state-machine.js + router.js + conversations.js) — in-process idempotent guard
- per-user _seenInboundTxids Map<user_id, Map<txid, ts>> + TTL 1h
- processInput 新 opts.inbound_txid arg → _idempotentGuard → return { reply: null, _idempotent_skip: true }
- router 短路 return null (silent skip, log 单行 不再 spam)
- relay ai.mjs 已有 txId 透传 → conversations.js → broker-v3/index.js → router.js → state-machine.js

### N4 + N5 (KI-12 silent skip 第 14+15 次, NWT 真链 audit 抓)
- N4 trade-protocol-filter.js _evaluateAutoTake rep_block: txid offerId.slice(0,12) 截 extexch- prefix 共享 → UNIQUE silent ignore. Fix: full offerId.
- N5 trade-protocol-filter.js handlePaid + order-machine.js: accepted → paid 直跳 + transition result 必 check, false 不记 false-positive chain_event.

## 4-month Owner 真痛终结

`Trader-B 一会儿自动发菜单 一会儿单子回复也没有发出去` (Owner 真测 multiple 截图)
真因 = catch-up replay 同 inbound source_txid → state-machine 再走 → 菜单 spam.
Layer 1 (relay _seen): in-memory only restart 清失忆.
Layer 2 (catchup-service NOT EXISTS replies): replies table 写 fail / trace_id mismatch 时漏判.
Layer B + D = 持久 (DB) + belt-and-suspenders (内存 1h TTL).

## 验证路径

NWT 真链 N7.1 case 重放:
1. ExtClient send DM "1" txid=T1 → Trader-B 走 BUY flow step 1 → DM ASK_QTY
2. console restart (模拟 _seen 清失忆)
3. catch-up loop /ingest/unreplied-messages 拉 → 旧 code 仍 return T1 (replies 表 fail) → relay replay → spam
4. 新 code Layer B: outbound exists in same conversation → NOT returned by catchup. silent.
5. 假设 Layer B 漏 (extreme edge): Layer D _seenInboundTxids 命中 T1 → state-machine return null → 无 spam.

## restart live

- console PID 3844 listening :3100 ✓
- broker-v3 router 透传 inbound_txid ✓
- catchup-service Layer B SQL 重写 ✓

J2 standby NWT 继续 T11-T12 + T-OTC settle real-chain test.
