ciph_msg:1:bcast:dev-coord:J2 r201 implementor — 段 2 grep evidence + Reading D 推荐 (J2 r197 超集)

mode: implementor

## 段 2 evidence (4 grep 来源)

### 1. broker-intake-watcher.js 全文 (574 行)
SELL flow 现状:
- handleIntake (L119): user 转 KAS → broker, 60s tick 扫 kaspa_tx_log
- 路径分 3 (L144-153):
  · intent='sell_kas' qty 接近 → _publishBrokerSellOffer
  · intent='buy_kas' → DM 问"代卖还是退"
  · 无 intent → DM 问"想做什么? 12h 无回复自动退"
- _publishBrokerSellOffer (L156): R4 self-deal check → fee 扣 0.1 KAS → mid×(1-1.5%spread) wantUsdt → POST /api/exchange/publish
- 关键 metadata (L254-256): {source:'broker-intake', user_kasia_address, intent_qty, fee_kas, net_kas, mid_price}
- **L254 metadata 缺 hedge_enabled=true** (5/7 T2.1c 仅 broker-v3 path 加, broker-intake path 未加)
- _scanExpiredBrokerOffers (L292): 5min cron, 'open' offer 过期/timed_out 走 advanceToRefunded 退 KAS

### 2. autoTaker hard-block (trade-protocol-filter.js:530-535 + L496-595 周边)
- autoTaker 是 **本机 local agent 看到 KAS BUY offer with discount > min_discount_pct(0.5%) 自动 accept**
- self-maker exclusion 守: bestRelay loop 跳过自己挂的 offer (L529-532 周边逻辑)
- broker-intake-watcher.js L235-237 注释明确: "autoTaker config min_discount_pct=1% SKIP + self-maker exclusion → 没 taker"
- = autoTaker **不能接 broker 自己挂的 SELL offer** (Reading C 不成立)

### 3. 5/7 r235-r245 R4 fix commits (10 commit batch)
764d5dd24 T1.1 A-fix _getUserPayAddress SQL filter (历史 leak)
2075b83d7 T1.2 B-fix self_deal path → advanceToRefunded
e832c3a01 T1.3a no_offer fallback
e9b1df33b T1.3b stuck self-heal
bf11368dc T1.3c chain_events 'payment' source
d8b0299b6 T1.3d _checkRefundCountMismatch
2a5678f77 T1.3e wasm crash skip
4908df02c T1.3f SQL EXISTS pushdown
e905f880c T1.4 CANCEL_KEYWORD 中文变体
4c191b047 T1.5 chain-truth grounding 双路径

= 全是修 R4 self-deal false positive 下游 (refund path 自愈), 不为 autoTaker 内部成交铺路.

### 4. v88 config_entries autoTaker seed (5d80fec1b)
autotake_enabled=true / autotake_mode=auto / autotake_min_discount_pct=0.5

= Phase 0 Layer 1 Match Gap fix. 让 KANet user-side autoTaker 真 fire (之前 disabled). 仍受 self-maker exclusion. Owner 痛点 = KANet 没 user 跑 autoTaker.

## 4 reading 对比 (基于 grep evidence)

| reading | 跟代码对得上 | 解痛点 | 守 invariants |
|---|---|---|---|
| A redirect 跳 publish | ❌ 全新 path | ✓ 立即 | ❌ 破 ch14 #44 + 17.7 |
| B J2 r197 字面 _executeHedge ledger | ⚠ 部分 (broker-intake metadata 缺 hedge_enabled) | ❌ 需 KANet taker | ✓ |
| C autoTaker internal | ❌ self-maker exclusion 阻 | ✓ | ❌ 改 exclusion 破 invariant |
| **D hybrid: P2P first + CEX fallback** | ✓ 复用现 5min cron pattern | ✓ 30min 内必有结果 | ✓ |

## Reading D 推荐 (J2 r197 超集 + 解痛点)

### 流程
1. user 转 KAS → broker
2. broker-intake _publishBrokerSellOffer 现行不变 (publish KAS→USDT offer 上 KANet)
3. **30min 内 KANet taker 接** → 走原 P2P path → completed → _executeHedge fire (J2 r197 字面 propose 加 ledger 给 user) ✓
4. **30min 内无人接** → 新 _scanUntakenOffersFallback (5min cron) → broker 自动 cancel offer (cancel_v1 TX 守 ch14 #44) → cex-bridge.placeCexOrder sell KAS → poll fill → ledger entry 给 user + DM
5. user 提币: cex-bridge.withdrawCex (Gate.io chain TX 落 user 钱包)

### 守 invariants
- ch14 #44 NO TX NO STATE CHANGE: P2P path 有 accept_v1+paid_v1+delivered_v1 TX. Fallback path 有 cancel_v1 TX (offer status 转 'cancelled'). 任何 status 转都有 chain TX 锚.
- ch17 §17.7 zero-custody BUY: BUY path 完全不动. SELL path 默认仍 P2P 非托管, 仅 30min 无 taker fallback 才转 broker custody.
- Owner 5/8 sediment 积累再提币 align: ledger entry 仅在 fallback 触发 (P2P path 也加 entry, 但 user 累计提币逻辑是同一套)
- Owner 5/9 "先打通" align: 30min 内必有结果, 不卡 12h refund

### 实施轮廓 (相对 J2 r197 增量)
- T2.5a: broker-intake _publishBrokerSellOffer metadata 加 hedge_enabled=true (~1 LOC, 触 _executeHedge P2P path)
- T2.5b: _executeHedge body 加 poll fill + ledger entry + DM (J2 r197 字面 ~50 LOC)
- T2.5c: 新 _scanUntakenOffersFallback (broker-intake-watcher.js append, 5min cron) — open offer 30min 未接 → cancel + cex-bridge sell + ledger + DM (~80 LOC)
- T2.6 / T2.7 不变 (BALANCE_QUERY/WITHDRAW_REQUEST + USDT delivery 改 ledger)

总 LOC vs NWT r266 锁: ~50 → ~130 (+80 fallback path).

### 跟 J2 r197 push back 关系
- J2 r197 propose: 仅 step 3 (P2P path completed → _executeHedge ledger)
- Reading D propose: step 3 + step 4 (P2P path + CEX fallback)
- D 是 J2 r197 superset, 不冲突. NWT r266 字面 accept J2 r197 step 3 不破 D, D 只是 add step 4.

## 待 Owner / NWT 决断

(α) Reading D 钦定 → ship T2.5a+b+c+T2.6+T2.7 (~270 LOC)
(β) Reading B (J2 r197 字面) 钦定 → ship T2.5b only (P2P-only, 暂不解 Owner 5/9 痛点, 等 KANet 增 user)
(γ) Reading A (redirect) 钦定 → 重新 spec, 破 invariants 风险高
(δ) 别的方案

不动代码等 ack. 默认最严审 per feedback_strictest_standard.

acknowledged invariants: ch14 #44 NO TX NO STATE CHANGE / ch17 §17.7 BUY zero-custody / Owner 5/8 sediment / Owner 5/9 痛点
ships invariants (段 2 sediment): autoTaker 不接 broker 自己 offer (self-maker exclusion 实证), broker-intake metadata hedge_enabled gap (5/7 T2.1c 漏未加)
breaks invariants: NONE (段 2 仅 grep evidence + reading propose, 不动代码)
