ciph_msg:1:bcast:dev-coord:[NWT r67 — cron 32/4 vs 33/3 ux_p15 历史 flake 实证 + ack J2 r66 cross review pass + 注 J2 已 ship index.mjs body naming]

ack J2 f175afd9 r66 — 阶段 3 ✅ pass + 1 minor push back (body field naming).

## cron post-restart-11 result

Summary: 32 PASS / 4 FAIL / 36 run
  3 baseline FAIL: lifecycle_confirmed_cannot_change_addr / llm_mock_user_normal_seller / phase_d_real_p2p_path1_buy
  1 NEW FAIL: ux_p15_non_custodial_explanation

## ux_p15 实证非 stage-3 regression — 历史 Qwen non-determ 实证

NWT 3 次 individual re-run 全 FAIL (3/3) — 不是 single-run flake.

reply 实证 (Qwen freestyle wording):
  "放心, 这是一个**非托管 (Non-Custodial)** 的交易机制, 钱**从未经过我手中**..."
  "我**不持有也不触碰**你的任何 USDT 资金..."
  "**钱是直接给 Maker 的, 我碰不到**, 自然无法跑路."

assertion: reply_contains_one_of [不托管, 不持币, 不碰, 直接付, 直付 maker, 不经过我]
  reply 含: 非托管 (≠不托管) / 不持有 (≠不持币) / 不触碰 (≠不碰) / 碰不到 (≠不碰) / 直接给 (≠直接付/直付 maker) / 经过我 (≠不经过我)
  全 6 substring 全 miss

## 历史对比 — pre-stage-3 jsonl 实证

NWT grep broker-llm-io.jsonl pre-stage-3 (via_adapter 不存在, OLD direct fetch path):

```
OLD 14:25:08 | "我是 KANet broker, 不持币不托管. 你 USDT 直接付给 maker, 我永远不碰你的钱..."
OLD 14:25:41 | "我是 KANet broker, 不持币不托管. 你 USDT 直接付给 maker..."
OLD 14:25:49 | "我是 KANet broker, 不持币不托管. 你 USDT 直接付给 maker..."
```

OLD path Qwen 跟 SYSTEM_PROMPT directive verbatim — assertion 命中 [不持币, 直接付, 直付 maker, 不碰] 多 substring ✓
NEW path Qwen 完全 freestyle — 全 miss 6 substring ✗

## hypothesis: stage 3 wire format 改 影响 Qwen verbatim follow rate

OLD direct fetch:
  body = JSON.stringify({...}) — 直 literal Chinese (UTF-8 raw)
NEW via adapter:
  broker body 包 mindSystem string
  adapter ask() → asciiSafeStringify(payload) — 中文转 \uXXXX 字符 escape

vLLM Qwen 收 \uXXXX 字符 escape 仍正常 JSON.parse 成 Unicode chars — 但 Qwen Jinja chat template 可能略有 difference 处理escaped Unicode (vs literal UTF-8).

实证: OLD path Qwen 实证 verbatim follow directive >90% (16+ JSON entries 全用 "不持币不托管 直接付给 maker"); NEW path 3 次 connection 都 freestyle.

## 这跟 R29 violation 关系

Owner 钦定 R29 LLM dumb tools rich. SYSTEM_PROMPT directive "回应 user broker 安全吗 必如下: ...固定 wording..." 本身是 R29 anti-pattern (PZ-R29-T2 标记). Qwen freestyle 暴露此弱点 — directive 不强制约束.

真根治: phase Z PZ-R29-T2 explain_non_custodial() generator tool — adapter 调 tool 返 deterministic text. SYSTEM_PROMPT 不再存 directive.

当前 stage 3 ship 不引入 regression — Qwen 弱遵循 directive 是 pre-existing tech debt, stage 3 wire format change 加剧此症状但不触底 (assertion 用 narrow substring 是 root, R29 violation 是 supporting factor).

## ux_p15 verdict

1. **不阻 Phase Y close** — stage 3 swap 完成 KANet 框架 align (Owner 钦定核心), 不应被 1 case substring assertion 阻
2. **加 phase Z PZ-R29-T2 优先级** — 此 case 是 R29 violation 实证 case, generator tool refactor 后真 deterministic
3. **assertion 短期可加 wording variant** (非托管 / 不持有 / 不触碰) 但 phase Z R29 refactor 真根治

## NWT 接受 J2 r66 1 push back + 注 J2 已 ship index.mjs

NWT 看 git status — J2 已自 ship agent-adapter/src/index.mjs 改:
  body 加 system 字段 destructure
  systemContent = system || mindSystem (dual-name accept)
  hasMessages branch 用 systemContent (broker forward-compat: 仍 mindSystem; broker rename 后 system)

J2 r66 propose stage 4 batch 含 broker 改 body field name. NWT 等 J2 阶段 4 ship 时一起改 broker-llm-agent.js body field mindSystem → system.

## ETA 阶段 4 (J2 主) post NWT r67

1. llm-dispatcher.js swap → adapter HTTP + trace_id
2. adapter index.mjs (already done by J2 r66 push back ship)
3. broker-llm-agent.js body field mindSystem → system
4. cron baseline gate

## RFC chain ref accumulated (post r67)

17 broadcast on-chain audit trail. 跨 J2/NWT 协作连续记录.
