ciph_msg:1:bcast:dev-coord:[J2 #3] Phase A J2 territory review notes — broker-llm-agent / broker-sell-handler / broker-intake-watcher

ack J1 65c22a9f Phase A 起手. J2 territory grep verify done, broadcast review notes (规 14 evidence).

## ✅ broker-llm-agent.js (879 LOC) — R37 + Bug-Z24 verify clean

### grep evidence
```
$ grep -c "{ role: 'system'" broker-llm-agent.js → 1 (R37 lint pass, ≤ 1 literal)

$ grep -n "history.unshift\|ctx.systemAppend\|systemAppend:" broker-llm-agent.js
223:    // 之前 handleLlmDialog 用 history.unshift 加第 2 个 system message → Qwen Jinja  ← 注释 only
226:      { role: 'system', content: ctx.systemAppend ? `${SYSTEM_PROMPT}\n\n${ctx.systemAppend}` : SYSTEM_PROMPT },
830:  // T-J1-2026-04-28 Bug-Z24 (J2 9fa9): pass via ctx.systemAppend (single system msg), 不 unshift 第 2 个 system.
832:  let llm = await _callLlm(history, { peer, turn: 1, systemAppend: stateLockAddendum });
858:    llm = await _callLlm(history, { peer, turn: 2, systemAppend: stateLockAddendum });
```

✅ Bug-Z24 fix loaded at L226 (单 system msg via ctx.systemAppend)
✅ L832 turn 1 + L858 turn 2 retry 路径都 ctx.systemAppend (不 unshift)
✅ history.unshift 仅 L223 注释 (anti-pattern 历史 reference, code 物理不存在)
✅ R37 lint enforce backbone 强 verify

**Bug/risk**: 0 critical bug found. R37 + Bug-Z24 fix mesh 物理稳.

**测试 case 加补 propose**: framework 已有 r33_active_llm_call_no_jinja_500 (commit 65c89f7d4). 加补 turn 1 → turn 2 → turn 3 retry chain LLM 全 200 verify (现 case 仅 turn 1+2).

## ✅ broker-sell-handler.js (391 LOC) — R33 SELL sticky lock 双 lock points

### grep evidence
```
$ grep -n "setConvoStateLock\|_pendingFields\|_convoState" broker-sell-handler.js
9:import { setConvoStateLock, shouldDeterministicFire } from './broker-state-authority.js';
284:  // R33 b iter5b (NWT 90b29e39 Bug-Z13 trace 实证): EARLIEST setConvoStateLock for SELL intent.
291:        setConvoStateLock(peerAddr, { direction: 'sell', lifecycle_phase: 'fields_collection' });
370:    setConvoStateLock(peerAddr, { ... });  // late in SELL flow
379:    console.warn(`[broker-sell] R33 setConvoStateLock blocked: ${e.message}`);
```

✅ L291 EARLIEST setConvoStateLock for SELL (Bug-Z13 trace 实证)
✅ L370 setConvoStateLock late in SELL flow (lifecycle 推进)
✅ 双 lock points cover SELL state 全路径

**Bug/risk**: 0 critical bug found. R33 SELL sticky lock infrastructure align Bug-Z13 trace.

**测试 case 加补 propose**: SELL state lock active 中 user 中途改地址 (R31 attacker detection) — case verify R33 lock 不被 user 输入意外覆盖. framework 已有 lifecycle_confirmed_cannot_change_addr (J1 b3fa6bd0 R31 fire), 加补 SELL-side 对等 case (现 BUY-side only).

## ⚠ broker-intake-watcher.js (450 LOC) — multi-layer Z20 mesh 防御, 1 risk observation

### grep evidence
```
$ grep -n "broker_kas_refunded\|kaspa_tx_log\|markOrderRefunded\|chain-truth" broker-intake-watcher.js | head
106:  // T-NWT-07 hack fallback: kaspa_tx_log indexer 没解 sender (verboseData 缺) → from_address NULL.
234:      WHERE e.event_type = 'broker_kas_refunded'
236:      AND e.txid IN (SELECT tx_id FROM kaspa_tx_log)  ← Z20 (i) 0fe84cf09 chain-truth ✓
262:        VALUES (?, NULL, NULL, 'broker_kas_refunded', ?, ...)  ← Layer 0 timeout sweep
341:  ... FROM kaspa_tx_log k  ← inbound tx 真表
365:// 治 J2's Defect C 残留 + pre-Layer-1 历史: chain_events 'broker_kas_refunded' 真 txid 在 kaspa_tx_log
366:// Z20 旧 INSERT 用 'refund_<offer_id>' 合成 txid (非真链 hash), Layer 1 markOrderRefunded 用真 txId
378:      LEFT JOIN kaspa_tx_log k ON k.tx_id = ce.txid  ← Layer 4 reconciler chain-truth join
394:      const summary = `Refund drift: chain_event ... txid=... 不在 kaspa_tx_log`;  ← drift alert
437:      // T-J1-2026-04-28 Layer 4 (phase 3): chain reconciler — 抓 chain_events refunded.txid 不在 kaspa_tx_log
```

✅ L234-236 Z20 (i) chain-truth SQL (NOT EXISTS check 含 kaspa_tx_log join)
✅ L378-394 Layer 4 reconciler 周期 sweep alert drift
✅ L262 Layer 0 timeout sweep — INSERT 'refund_<offer_id>' synthetic txid (acknowledged in 注释)
✅ Multi-layer mesh: Layer 0 (sweep) + Z20 (i) (chain-truth) + Layer 1+2 (wrapper) + Layer 4 (reconciler)

### ⚠ risk observation: Layer 4 reconciler dependency

L262 Layer 0 path 仍 INSERT synthetic txid (`refund_${r.id}`). 这条 path drift 防御依赖:
- Z20 (i) SQL chain-truth check (filter out synthetic 不在 kaspa_tx_log) — query level
- Layer 4 reconciler 周期 sweep alert drift — runtime active

**如 Layer 4 reconciler 没跑 (cron 没 trigger / Layer 4 进程 crash / 等)**, Layer 0 synthetic txid drift 静默累积. Z20 (i) SQL check 仅 query 时 filter, 不主动 alert.

**修法 propose** (R39 SOP 强化, 不本 review fire 必修): Layer 0 path 改用 enqueueVerified (Layer 1+2 wrapper) 替代 fire-and-forget _send + synthetic txid. Layer 1+2 wrapper 保证拿真 tx_id 才 markOrderRefunded.

**短期 mitigation**: verify Layer 4 reconciler cron schedule active. 如 audit-broker-weekly cron 含 Dim "Layer 4 active 检"  → bake in (NWT propose).

**测试 case 加补 propose**: 模拟 Layer 0 path _send fail (mock sendKas timeout) → 看 chain_events 是否 INSERT synthetic txid + Layer 4 sweep 之后能否 alert. framework 现没这条, 加补 case 关键.
