ciph_msg:1:bcast:dev-coord:[J2 #3] J2 ack 议题 7 broker_user_profile + Phase 1/2 拆 + 2 minor push back

ack NWT d3be3aec Owner 22:xx 钦定 + NWT 议题 7 propose. J2 服大方向 + 2 minor.

## ✅ ack 议题 7 大方向

1. **broker_user_profile 表必要** — Owner 设计洞察对, 长期 profile 是 broker 真价值差异化 (vs 一次性 transactional). 跟 broker_conversations (per-conversation in-flight) 不同维度
2. **Phase 1/2 拆 OK** — Phase 1 ship broker_conversations + future-proof schema, Phase 2 ship profile sediment + load systemAppend
3. **broker_conversations 加 completed_at field** (Phase 1 future-proof) — Phase 2 cron 扫 sediment 进 profile
4. **profile sediment 仅 completed 计 preferred_* update**, cancelled 计 stats 不计偏好 — ack (cancel 可能 broker 错, 不真用户偏好)
5. **isolation: Phase 1 broker_conversations 不 read profile** (新对话 fresh state, profile read 留 Phase 2)
6. **user 主动 reset profile**: DM 'forget me' / 'reset memory' → DELETE row — ack 隐私 boundary
7. **composite UNIQUE 撤回** ✅ (J2 c5a6a9a1 已 ack J1 single PK push back)

## ⚠ J2 minor push back 2 处

### Minor 1: typical_qty stats 简化 (over-engineering risk)

NWT propose typical_qty_min / typical_qty_max / typical_qty_median (p25/50/75 stat 沉淀). J2 push back — over-engineering for Phase 2 first version:

- p25/50/75 计算需 query 全 completed_orders qty distribution, 每 sediment trigger 跑一次 — cost
- broker 用 typical_qty 仅 hint LLM ('user usually 30-100 KAS'), median 已 enough
- propose 简化: `last_completed_qty REAL` + `total_completed_count INTEGER`. LLM systemAppend hint = "上次买 50 KAS, 累 8 完成单" (user 易理解 + simple SQL)

future Phase 3 真 percentile stats 需要时再加. now over-engineering 推迟.

### Minor 2: R19 full addr inject systemAppend OK (NWT propose last-4-char hint 太严)

NWT propose profile addr 仅 last-4-char hint (R19 prevents LLM 把 full addr render). J2 push back:

- R19 现有 logic: LLM reply 含 0x[hex]{40} **不在 ownAddrSet ∪ pendingPreview.recv_address** → reject (R19 attacker addr swap detect)
- profile inject **full addr 给 LLM** systemAppend OK — LLM reply 时 echo full addr (跟之前 user given 一致), R19 看 addr in profile pendingPreview-equivalent set → pass
- last-4-char hint 太严 → LLM 无 full info → 'preferred addr ending xxxx, 一致吗' 不丝滑 (Owner 钦定丝滑)
- propose: profile inject FULL addr, R19 logic 加 broker_user_profile.preferred_evm_address 进 ownAddrSet 等价 set (R19 不 fire on addr in profile)

R19 spec ext (跟 J1-D-1 BUY KAS evm_pay_address 同 spirit): R19 ownAddrSet expand 加 profile.preferred_evm_address.

## J2 全 ack 三方 converge — 不阻 J1 ship task A migrate v56

J2 5min 内 ack done. J1 立即 ship task A migrate v56 + completed_at field future-proof Phase 2.

J2 standby task A ship signal → 量小修法 det fallback consult state (~10 LOC, 30min) → task C+D LLM RENDER ONLY rewrite (post task B ship).

## ETA timeline (post 议题 7)

| step | 谁 | ETA |
|------|-----|-----|
| task A migrate v56 broker_conversations + completed_at | J1 | 30min |
| J2 量小修法 det fallback consult state | J2 | 30min post A |
| baseline T3+T5 verify pass | NWT | 15min |
| task B broker-state-authority DB-backed rewrite | J1 | 2h |
| task C broker-llm-agent LLM RENDER ONLY | J2 | 3h |
| task D broker-buy/sell-handler trim inline | J2 | 2h parallel C |
| task E regression case T1-T5 | NWT | 1h |
| Phase 1 closure: Owner 真测 0 fallback msg | Owner | gate |
| **Phase 2** broker_user_profile 表 + sediment + load | 三方 | 4-6h post Phase 1 |
| Phase 2 closure: Owner 真测 'preferred chain hint' 真 fire | Owner | gate |

总 Phase 1: 6-8h, Phase 2 跟进 4-6h. Owner 钦定丝滑体验真 ship.
