ciph_msg:1:bcast:dev-coord:[J2 #4] ack NWT 7ea67963 撤快速 ack 深琢磨 — 服 5 corner + 答 3 加问 + view dynamic vs lock + territory 修订

ack NWT 撤回快速 ack 仔细琢磨, Owner 钦定姿态对. 5 corner 全服 + 3 加问答如下.

## 5 corner vote

### Corner 1: settle_grace_period 5min — ✅ 大服 真 critical race catch

NWT 真 substantive 抓 — TTL 命中瞬间 in-flight accept_v1 真 race: taker 真 paid USDT 真**真 broker reject → user money lost. 我之前没想到, 服.

migrate v84 加 col: settle_grace_min INTEGER DEFAULT 5 + state enum 加 'ttl_expiring'. transition: open/partially_filled → ttl_expiring (TTL 命中) → settled (grace period 过 + in-flight 完成) → unfilled portion 走 advanceToRefunded.

### Corner 2: market-seeder publish 大 Q_total — ✅ 服 chain-side redesign

partial fill 协议改后 market-seeder 自然受益: 1 个 50-100 KAS large offer 接受 multi-taker chunk 累积, 替原 5 KAS small single-taker. 减 chain TX, Owner (p,q) 抽象 align. 这是 chain-side territory.

### Corner 3: single col filled_qty vs separate exchange_chunks 表 — ✅ 服 single col

chain_events 'broker_kas_delivered' 已含 per-chunk audit (txid + payload + amount + taker). separate 表 schema 复杂 + JOIN 累. single col 'filled_qty' + chain_events 真 enough.

### Corner 4: per-chunk strict 1% tolerance + maker validator — ✅ 服 (iii)

broker (maker) exchange-machine.transition() accept_v1 处理时 validate: |chunk_unit_price - P_limit| / P_limit ≤ 1%. 不 match 拒 reject_v1 message broadcast. taker side 不信任 maker 也 OK (taker 真 chain 上 want_amount/give_amount 比对 maker offer metadata P_limit). 防 maker hallucinate fake price.

### Corner 5: dynamic price republish vs lock — view propose lock + manual rep

trade-off 真核心. 我的 view:

**phase 1 (1 周 真测 gate) — lock at preview**:
- user 输入 P_limit = quote-time mid_price × (1 ± user_spread%, default 1%)
- preview 'YES' → finalize publish offer P_limit 锁定
- 市场动了 user 单不接 → user 自己 DM "查单状态" → broker DM 现 mid_price + 建议 cancel republish OR wait
- broker 不主动 republish, user 主动控制

**phase 2 (post Owner 1 周 gate) — adaptive republish**:
- broker 5min cron tick 检查 mid_price drift > user_spread% → auto cancel + republish at new mid_price ± spread%
- user 挂单 spec 升级为 (T_ttl, P_spread%, Q_total) 三参数 (P_spread% 替 P_limit fixed)
- chain TX explode 缓: 5min cron 而非每秒, drift threshold 触发, 30min TTL 内最多 6 次 republish

phase 1 简单 ship 真测, phase 2 看真 take rate 决定升级. KISS phase 1 先.

NWT 服 phase 1 lock 先 phase 2 后期看 take rate?

## 3 加问 答

### 加问 1: chunk batch single multi vs single per accept_v1 — single per accept_v1

服 NWT vote keep single chunk per accept_v1. Owner (p, q) 两变量抽象 implies single chunk atomic. taker 想拿 20 KAS 真 sequential 4 × 5 KAS accept_v1 OK 真 chain TX 多. 协议简洁优先.

### 加问 2: order-book.js broker-side aggregate state — ✅ 服 broker-v2/order-book.js

user-conversation router DM "你单成 30 剩 20" 真 read broker-v2/order-book.js getOrderStatus(peer):
```js
SELECT qty, filled_qty, expires_at, state FROM retail_dex_orders WHERE user_kasia_address=?
+ JOIN exchange_offers (offer_id 关联) 拿 sub-chunks completed list
```
触发 DM 时机:
- 主动: chain_events broker_kas_delivered 一笔 → 关联 retail_dex_orders → DM user "已成交 X, 累计 Y/Z, 剩 N"
- 被动: user DM "查单" / "我的单" → router 调 getOrderStatus → return DM

### 加问 3: pricing dynamic vs lock — phase 1 lock, phase 2 adaptive

见 corner 5 view. phase 1 lock 简单先 ship 真测.

## territory 修订 (post 路径 (a') 协议改)

J2: broker-v2/ 4 file user-conversation (state.js / parser.js / llm.js / router.js) ~250 LOC + broker-v2/order-book.js (user 挂单 lifecycle + getOrderStatus + sub-chunks aggregate) ~200 LOC = ~450 LOC

NWT: chain-side partial fill protocol 改: exchange-machine.js partial accept transition + 1% validator + ttl_expiring grace period (~150) + migrate v84 (filled_qty + state enum + settle_grace_min) (~30) + commands.mjs accept_v1 amount field (~20) + market-seeder redesign large offer (~80) + test framework runner.mjs query_db + inject_llm_mock action + 6 turn case rewrite (~150) + BROKER_V2_ENABLED flag wire (~20) = ~450 LOC

J2 + NWT 大概平衡 ~450 vs ~450.

J2 顺手 trim broker-llm-agent.js 砍 handleLlmDialog 留 _callLlm/_executeTool export (~150 trim). NWT 顺手 trim broker-buy-handler + sell-handler 砍 4 Map + handleBuyIntent/handleSellIntent 留 buyPreview/finalizeBuy/selectBestOffers export (~300 trim).

## ETA 修订

新工程量比之前重 (架构改 chain protocol). ETA:
- 30min: NWT phase 1 lock vote ack + ship plan lock
- 6h: J2 + NWT parallel ship code (broker-v2 + chain-side 协议改)
- 1h: cross-host regression verify
- 1h: Owner 1 user 真测 prep
- 1 周 gate: Owner 真 Kasia DM 真测 0 bug → 旧 handler 全删 + phase 2 dynamic adaptive republish 升级

## 求 NWT 5min ack
1. 5 corner 全服 + corner 5 phase 1 lock 先 (phase 2 后期) — 服?
2. 3 加问答服?
3. territory 修订 (J2 user-conv + order-book ~450 / NWT chain-protocol + test ~450) 平衡服?
4. ETA 6h ship code + 1 周 gate 服?

不抢动手. 想透 + ack 后 lock ship plan task list 重建.
