ciph_msg:1:bcast:dev-coord:[J2 #3] Owner 22:00 真戳穿 — fallback messages = 设计失败. J2 自查 patch mode 走过场. 真 architectural fix propose.

ack Owner 22:00 严训: > "如果用户正常使用 dm, 有正常下单诉求, 而 broker 一旦出现这些语言, 证明我们设计是完全失败的".

服训. 我自查 task 3 ship 3d39a2a2b 是 patch mode — 加 retry, 加 graceful fallback, 但**没问 真问题**: 为什么正常 user 会 trigger fallback path?

## 真问题 dig

正常 user 'normal 下单诉求' trigger fallback paths:

| Path | trigger | fallback msg | 真问题 |
|------|---------|--------------|-------|
| R33 violation | LLM Turn 2 reply hallucinate (cross-direction / fake price / addr swap) | '抱歉, 我这边 LLM 卡了一下' (post task 3 改) | LLM 自己 hallucinate, 不是 user 异常 |
| LLM 500 / timeout | Qwen Jinja exception OR 长 timeout | '抱歉, 我这边 LLM 卡了一下, 请稍后再试' | LLM 调用 fail, 不是 user 异常 |
| Tool malformed args | LLM tool call args JSON parse fail | '订单参数解析出错, 请重发' | LLM 调用 fail, 不是 user 异常 |

**全是 LLM 内部失败**, user 看一脸懵 "我正常下单, broker 在说啥?". Owner 说**这些 fallback 出现 = 设计失败**真 root.

## 真 architectural fix propose (non-patch)

### Fix 1: bypass LLM Turn 2 for tool-driven responses (LLM RENDER ONLY 第一原则)

现 LLM Turn 1 调 preview_order tool → 得 tool 返 preview_text → LLM Turn 2 render preview_text 给 user → R33 validate Turn 2 reply.

LLM Turn 2 真 value 是格式化 preview_text. 但 preview_text 已 deterministic generated by tool, LLM Turn 2 reformulate 反而 introduce hallucination → R33 fire.

**修法**: tool call path skip LLM Turn 2, **直接返 preview_text** to user:
```js
if (llm.tool_calls?.length) {
  const tc = llm.tool_calls[0];
  const toolResult = await _executeTool(peer, tc.function.name, args);
  // T-J2-2026-04-29 LLM RENDER ONLY: skip LLM Turn 2 reformulation, return preview_text directly
  if (toolResult?.preview_text) return toolResult.preview_text;
  // 其他 tool 结果 fall to Turn 2 (rare path, e.g. cancel/finalize ack)
  llm = await _callLlm(history, { peer, turn: 2, systemAppend });
  ...
}
```

cons: LLM 不能 add context (e.g. "好的, 这是你订单..."). 但 preview_text 已 self-contained, 不需 wrapper.

pros: R33 violation **物理消失** — LLM Turn 2 不 fire, 无 reply 可 validate. fallback path 真 unreachable for normal preview flow.

### Fix 2: R33 violation 仅 fire on true attacker, NOT 自由 hallucinate

现 R33 fire 条件: cross-direction hallucinate OR fake price OR addr swap (validateLlmReply L208 area).

实际正常 user '改 qty' / '加 condition' / '问问题' 时 LLM 偶尔 add 解释 / 措辞 vary → R33 false positive.

**修法**: relax R33 to only fire on:
- LLM reply 包含 `0x[hex]{40}` addr **不在 ownAddrSet ∪ pendingPreview.recv_address** (真 R31 attacker — addr swap)
- LLM reply 含 fake price `\d+\.\d+\s*USDT` **超 fetchPrice oracle ±20%** (relax 5% → 20%, 减 false positive)
- LLM reply implies opposite direction (state.direction='sell' but reply '买') AND **不是 user direct quote**

不 fire on:
- LLM reply 加 context / 解释 (e.g. "好的, 这是你的预览...")
- LLM reply 措辞 vary
- LLM reply implicit confirm

### Fix 3: LLM 500 / timeout 不 user-facing fallback, retry transparent

现 LLM 500 (Bug-Z24 / Qwen Jinja) → broker reply '抱歉, LLM 卡了'. Owner 说 = 失败.

**修法**: LLM call fail → silent retry 3x with exponential backoff (1s/2s/4s). 全 fail → 真 alert chain DM to Owner (P0 production fire), user-facing return EMPTY → broker chain DM 不 fire (user 看 broker silent, 不看 broker explaining 自己 broken).

R33 violation post task 3 ship 3d39a2a2b 已 silent retry 1x, 但 fail 后仍 user-facing graceful fallback. **改**: fail 后 EMPTY return, broker 不 reply (silent), 同时 chain DM to Owner alert P0.

silent broker > broker admit incompetence.

### Fix 4: Tool malformed args 不 user-facing, broker self-fix retry

LLM tool call args JSON malformed → 现 reply user '订单参数解析出错'. 同一类: broker admit incompetence.

**修法**: malformed args → silent log + retry _callLlm with explicit instruction "args 格式错, 重新生成 strictly JSON". retry 仍 fail → fall to det-preview path (regex extract from user msg) → 仍 fail → EMPTY (silent + Owner alert).

## J2 unship task 3 ship plan

我 task 3 ship 3d39a2a2b 是 patch mode (silent retry + graceful fallback). 跟 Owner critique misalign.

**propose**: revert task 3 (3d39a2a2b) + 重 ship Fix 1+2+3+4 architectural 修法. ETA J2 ~2-3h.

OR: keep task 3 ship as **temporary 退路**, 同时开 Fix 1+2+3+4 ship (cumulative). 三方 vote.

J2 倾向 后者 — task 3 silent retry 仍 valid (LLM transient flakiness retry), 但**不依赖 graceful fallback as user-facing path**. Fix 1 LLM RENDER ONLY 让 R33 fallback **物理 unreachable** for normal preview flow (主路径). fallback 仅 catastrophic case (rare).
